A Rare Think

As a householder you seemingly draw on electricity to power a number of things in and close to your own place of residence. While heating your home tends to be the greatest monthly outgoing both in terms of home energy usage, your own homes’ monthly electricity tariff may also reflect common appliances which are powered by electricity as well. Read on and you may spy quite a few tried-and-true tips for cutting down energy – and, in addition, money; get into a habit of following them and you and your family will probably be pleasantly shocked thanks to the magnitude of the reward in your own next regular bill.

In cases where a home is not insulated well, energy gets out. As you most likely aren’t keen on the idea of heating the immediate surrounding areas, buy top quality insulation and also get it fitted by professionals. Do this and it may have an incredibly helpful impact on your own energy charge each month.

Fill in cracks in your home’s walls. Energy also regularly escapes from small cracks & gaps around window sills door ways, ducts and pipes. Draw on caulk or weather stripping in order to cover up & cram in these cracks; less heat will be wasted and you’ll use less electricity however regularly you get your bill.

Turn down the thermostat. On extraordinarily blistering days and nights it’s enticing to set the home’s heating all the way up. Then again, you’re going to pay for that luxury once your home energy tariff travels to you in the mail. Leave your own thermostat close to 48C so that you don’t end up wit a higher bill than you might otherwise have done.

Turn down the water heater. Putting the home’s water in your water heater very hot might be a wasteful idea. Turn the thermostat on your water heater down to around 48 C in order to enjoy lower monthly home energy demands.

Bundle up. In cases where you’re outstandingly chilly, don’t 5 up the home’s thermostat; instead, bundle up in a couple of layers of clothing. Wrap yourself in a thick blanket for additional warmth.

Conserve energy, 3 washing clothes and also dishes. Tumble dryers and other washing machines often need gas and electricity to run. Consistently wash full set of clothes & crockery in order that you have to use these machines as infrequently as possible. Keep the lint traps in your dryer clean and line-dry your clothes whenever possible. Set your dish washing machine to use less hot water & don’t Exploit its dryer function.

Invest in energy efficient appliances. If it’s been a while since you’ve bought a new dishwasher, water heater, tumble dryer or other major appliance; you should know that newer models are much more energy economical. Whilst it is true that you might well pay more money to purchase one new, they will curb your gas tariff in the medium term. It might be worth contacting your energy supplier to find out if they can offer further assisitance.

Contact your energy supplier. Innumerable utilities firms now offer their customers additional listings on saving energy, so it may be worth contacting them or seeing whether they suggest either free promotional information or gadgets in order to improve your family’s dwellings effectiveness.

UK based Internet service provider TalkTalk has come up with a service for home movers who want to skip the lengthy process of applying for a new broadband connection while shifting houses.

The TalkTalk Home Mover Service, as it has been aptly named, can be availed by current TalkTalk customers for £29.99, while new customers can do the same for £59.99. This eliminates the need for signing up to BT as a bridge service while moving to a non-cable area (click for more info on cable broadband).

According to TalkTalk’s estimates, in the process of signing a 12-month contract with BT and then cancelling it before its expiry date so they could return to TalkTalk’s services, customers end up spending around £120. However, with TalkTalk’s Home Mover Service, the entire responsibility for getting an Internet service up and running in the new home lies with TalkTalk, and the customer pays far less than £120.

TalkTalk’s managing director, Wendy Becker, said that TalkTalk was glad to reduce the worries of home movers with this new service. Most of the hassle of broadband migration, and indeed most of the cost, will now be borne by the company, and home movers can be assured of getting a functional home phone and Internet connection in quick time.

TalkTalk’s current customers can access the Home Mover Service by calling the customer support at 0870 444 1820. This should be done as soon as possible once the moving date is known, and at least fourteen days in advance. New customers can use the dedicated number 0800 049 1424 to sign up for the service.

Most full-time office workers have an employer-provided e-mail account, and chances are, it’s with Microsoft Outlook. Many of us send and receive dozens of e-mails per day. Here are some tips about making the most of Outlook’s substantial capabilities when you are the sender. Not taking advantage of what is available is like keeping your brand new Ferrari continually in first gear.

If you think you are already on the Outlook fast track, at least slow down long enough to check out the points lower in the list (arranged roughly from most to least important). Since nearly all of us are self-taught in our Outlook expertise, we are all at different levels. Now, let’s rev ‘er up and see what she’ll do!

1. Know when to call and when to e-mail.

   The rule of thumb is, the less intrusive you are the better, which is definitely e-mail. If you need to transmit and/or receive information in a hurry, however, a phone call is better. But what if you know the recipient is tied up in a conference call though still in their office? You might be able to reach them by e-mail without interrupting their call. E-mail also works better if your target is away from the office, especially if you know they have a Blackberry. If a dialogue between you is necessary, a phone call is probably more efficient.

2. Carefully craft your subject line.
   

   Unfortunately, too few people give their subject line the attention it deserves. How many times do you get an e-mail with a blank subject line or one that is unhelpful, like “message for you”? Since many of us scan our inbox without the reading pane turned on, the subject line and name of the recipient is how we determine whether to open the message.
   Make your subject line convey the most vital information in about six to eight words. If that number of words is the entire content of your message, consider letting the subject line carry the entire message. If you choose this option, end the subject line with ““, which stands for “End of Message.”

3. Carefully word your e-mail
   
   Remember Rudyard Kipling’s famous poem, which begins:
   

   I keep six honest serving-men
   
   They taught me all I knew);
   Their names are What and Why and When
   And How and Where and Who.

   These six features should be prominent in your e-mail messages. If at all possible, put them all in the opening paragraph, because, unfortunately, many people read the first paragraph
   of an e-mail and then scan the rest of the message. If the highly pertinent material is not in the opening paragraph, they will probably miss it.

4. Make a habit of reading over the e-mail before you send.
   
   Just a few seconds of proofreading could save you the embarrassment of misspelled words or tangled grammar. Sometimes the mistake materially changes the message, as in leaving out the “not” in the sentence, “I will not be able to work
   overtime on Thursday evening.” Give yourself some reassurance, and save yourself a lot of grief.
5. Learn how to recall a message.
   
   Have you ever discovered, three seconds after you hit “Send”, that your outgoing message has a serious error? You can recall your message, and, if you do it immediately, you stand a good chance of retrieving your mangled message without your recipient’s knowledge of your mistake. Here’s how to recall a message:
   • Go to the “Sent” folder and open the message from there.
     NOTE: You have to actually open the message. You will not be able to access “Recall” from the Inbox’s reading pane.
   • With the cursor in the “Message” field, select “Recall this message” from the Actions menu.

6. Set the levels of importance and sensitivity.
   Outlook provides three options to identify the relative importance of your message: high importance, signified by a red exclamation point; low importance, indicated by a blue downward arrow; and normal, the default setting. Just use the high-importance icon sparingly; no one listens when you cry “Wolf!” too often.

   The same holds true for the sensitivity levels (confidential, private, personal, and normal). Both of these bundles of options are available in a dialogue box that pops up when you select the “Options…” menu (it only appears when you are Composing a message). If you select one of the levels other than “Normal,” a pre-set message will appear above the “To/From” rows with the preset messages. Because it appears there, however, and not in the message window itself, an inattentive recipient can easily overlook it. You might desire, therefore, to repeat the sensitivity or importance message within the message window.

7. Flag your message for follow-up.
   
   While composing your message, if you click on the menu icon that looks like a pennant on a stick, a dialogue box will appear that permits you to select from a variety of options to identify what kind of response you are expecting. Your options include: Call, Do not forward, Follow up, For your information, Forward, No response needed, Read, Reply, Reply to all, and Review. You also
   have the option of setting the day and time (in 30-minute increments) for the response deadline.

   Once more, when the recipient gets your e-mail, all of this information will appear as a column within the Inbox if that column is turned on and above the “To/From” rows of the message itself. Keep in mind that your recipient might easily overlook this information unless you repeat it in the message window. In e-mail communications, a little redundancy is a good thing.



8. Use read receipt requested when your message requires an immediate response.
   

   That same “Options…” dialogue box permits you to check “Delivery receipt” (almost never needed for internal e-mailing) and “Read receipt requested.” Requesting a read receipt accomplishes two purposes: it lets you know that the recipient opened your message, and it conveys to them a sense of importance and urgency. If these two purposes do not pertain to your message, uncheck read receipt requested.

   Remember that the recipient can by-pass your request either by reading your message from the reading pane or by choosing not to return the receipt. Requesting a read receipt, however, can be useful if you are unsure whether the recipient is available. If
   no receipt from your urgent messages gets back to you, you’d better try making a phone call.

9. Turn off receipt requested and read receipt requested, especially when e-mailing to large group.
   
   Turning on receipt requests unnecessarily is a good way to flood your Inbox with meaningless messages, especially if you e-mail goes out to a large group. Do yourself and them a favor: uncheck it in the “Options…” dialogue box.

By learning how to use Outlook–or whatever e-mail application you have–more effectively, you can boost your productivity with little or no cost. Happy e-mails to you!

Now a days managing files and folders on PCs seems to be a critical task for network administrators and data storage managers due to huge capacity hard disks and millions of files and folders.

This article will help you in two ways

1. Understand the disk space allocation and wastage.

2. Understand how to manage your disk space.

Topics covered

• 1. What is File Allocation Table (FAT) ?
• 2. Disk Efficiency and FAT.
• 3. What is Wasted Space. ?
• 4. Solution.

What is File Allocation Table

The FAT is a roadmap, or index, that points to the location where all the information in files is stored on a floppy disk or hard drive. The FAT is extremely important because the system uses it to store and retrieve files containing information.

When you save a file in Windows, it is stored in multiple pieces (in clusters made up of multiple sectors) on the disk. Windows also saves the roadmap, or index, that points to these clusters in two copies of the FAT (File Allocation Table). The FAT contains the directions to all the pieces of your files, so that applications can find them again later

Disk Efficiency and FAT.

Every file on your system is stored in clusters in your hard drive, the maximum of one file can be stored in a particular cluster, so this results in wastage if the file is under the cluster size. The current FAT version (FAT16) organises files in 32K clusters in drives over 1.2gig, while FAT32 will use a minimum cluster size of 4K. This means that a 3K file wastes only 1K of disk space on FAT32, while it wastes 29K of space on a standard FAT system. This wastage can result in over 50% of a 2gig drive being wasted. See the table below.

What’s a cluster and why does cluster size matter?

The whole problem of wasted space arises from the fact that DOS allocates file space in “clusters”. Clusters are sequentially numbered on the disk, starting at 0, and cluster numbers are used both in the FAT (file allocation table) and in the individual directory entry for each file.

Allocation by clusters means some space on the disk will be wasted. Regardless of the actual length of a file as reported by the DIR command, the file will actually occupy a whole number of clusters on the disk. So a 1-byte file will actually use a whole cluster, a file that’s 1 cluster plus 1 byte long will use 2 clusters, and so on.

Is this serious? It can be, depending on the pattern of file sizes on your disk. For instance, if you have an 2GB disk with 5,000 files on it, about 100 MB of your disk is being wasted. And the figures can be much worse, depending on the pattern of your usage. One user reported copying 450 MB of files to a 1.6 GB disk and having them take up 600 MB! As your disk approaches being full, you may wish you could squeeze some extra space out of it instead of buying a new disk.

How does cluster size depends on hard-disk size?

As mentioned above in the table the cluster size for various partition sizes so that you can make intelligent choices about how to partition your hard disk.

From the above table we see that even 2.1 GB drive is over the 1023 kilo-byte limit for 16 KB clusters and therefore its cluster size (unpartitioned) is 32 KB. With a 32 KB cluster, even a 1-byte file will use 32 KB of disk space. A file whose length is 32,769 to 65,536 bytes will likewise use two clusters (64 KB), and so on for higher file sizes.

Even so, you may be inclined to think this is no big deal. But think about it: if you have a 2.1 GB drive with 5,000 files, you’re probably wasting about 160 MB.

How are cluster sizes determined?

Clusters are always some power of 2 times 512 bytes, but just which power of 2 depends on the disk size. Why should this be so? I mentioned above that clusters are numbered sequentially. The problem is that the directory structure and the FAT have room for only 16 bits for a cluster number. Since the largest unsigned number that will fit into a 16-bit field is 2^16-1 = 65535, the disk can hold at most 2^16 = 65536 clusters. This gives the formula

disk size

cluster size = ———, rounded up to a power of 2

65536

In general the wasted space per file will be half a cluster.

—–

What is Wasted Space?

Whenever a file is created, space will be allocated to the file in the form of clusters. A cluster can be of 8 KB , 16 KB or 32 KB depending upon your hard disk partition size. Following is the chart for cluster size.

FAT FAT32

Partition Size Cluster Size Partition Size Cluster Size

128 – 256 MB

4 KB

1 – 8 GB

4 KB

257 – 512 MB

8 KB

8 – 16 GB

8 KB

513 – 1024 MB

16 KB

16 – 32 GB

16 KB

1025 – 2048 MB

32 KB

>32 GB

32 KB

So the formula for wasted space is Wasted Space = Allocated Space – Actual File Size.

We will take an example of file which is of 900 bytes in size and your partition type is – FAT and its size is 1024 MB. So the allocated space for your file will be 16384 bytes or 16 KB whether you store 900 bytes or 1 byte in the file. So the wasted space in this case will be

Wasted Space = 16384 – 900 = 15484 bytes.

So the conclusion is : Lesser the file size, more the wasted space.

Solution

So to analyze how our disk space is being wasted we need a smart program which will show us the space hogging files and their locations.

We are working with File system softwares since last 2 years. We have developed a powerful disk space analysis and cleaning software – DiskAnalyzer Professional 1.5 which allows you to take control of your disk space and reclaim gigabytes of lost disk space.

According to most people, there are two types of hard drives: those that have failed and those that will fail. But for folks who use Data Recovery Services, there is a third type of hard drive: one that does not fail.

A hard drive is the most vulnerable part of a computer; it has moving gears and is hence prone to wear and tear. So when you need hard disk data recovery, you must deeply consider the service and practice of the various repair companies in your area. A company that has been around the block more than a few times is ideal.

But more importantly, experts that ask questions and appreciate your situation are a necessity; companies that approach your needs in an impersonal way simply cannot diagnose your computer problems properly. For example, an expert who is on hand to ask specific questions about your hard disk will know whether or not to go about repair with mere software or through more professional means.

There are a variety of problems that lead to hard drive failure. If the hard drive is part of a mirror set, mirrored stripe set, or stripe set with uniformity, then all you will need to do is replace the drive – any lost data will mechanically regenerate.

A local service company can handle all your concerns though. Fixing a hard drive yourself is a tedious process, requiring lots of time and even research. Your next-door neighbor might be a computer geek, but that doesn’t mean his or her advice is remotely accurate. After all, a computer can fail for many different reasons and they are not always easy to pinpoint.

The ideal solution is usually to replace a failed drive and re-establish your backup. This does not always work though, as many people find the necessary backup is outdated or sometimes, non-existent.

If a hard drive is beyond repair, data recovery is obviously not an option. So prepare for unexpected charges; you might have to buy a whole new drive. In this case, just be careful when replacing it, as you don’t want to lose your data.

If you’ve been kicking around the idea of building your own computer, it actually isn’t a bad idea. It’s easier than you might think, and you can probably come out with a system that gives you more kick for your money, than you’d see in retail, or those made-to-order places. There are mainly two ways you’re going to see the benefits here:

1. You can see the money you’re going to save on this right up front. Just do a search on Cnet.com under “Compare Prices” for any random PC component you see in the stores, and you’ll know what I’m talking about. In most cases, you’ll cut out the full-retail markup, and then some. You’ll find brand new, sealed, in-box items lower online than you’ll ever find in any store.

2. The quality of the parts you’re getting is much better than what they put in pre-assembled, store-bought computers. You’ll know which brands mean quality. You could have a Creative sound card and a video card made by ATI or nVidia; the price difference is negligible, and we’re dealing with quality and performance standards that dwarf any no-name components they put in store bought systems, so they can keep their costs down. Many times, computer manufacturers like just use a cheap motherboard that has everything, your sound, video, etc., integrated into it; you get a third-rate version of everything.

Here are the main parts, or the basic building blocks for what you’ll need when you build your own computer.

1. A Motherboard. I talked about this a little earlier. All computers have one, but a good motherboard is just a fast connector that’ll hold lots of memory and extra slots for expansion components. Steer clear of motherboards that have “built-in” this or “integrated” that, because they’re almost always of lousy quality. It does help to have all your USB ports, keyboard plugs etc., on your motherboard, however. I have an onboard LAN that works pretty well, since a LAN is a LAN, but there were some driver issues with it when I put it together.

2. The Processor, or CPU. This is the “brain” of your computer. The kind of CPU that you can get depends on the kind of board that you picked out. The market is pretty much Intel Pentium 4 or AMD. Most people who are interested in higher power and long-term use tend to opt for the Intel.

3. Video Card. This is easy. Your motherboard either has a PCI Express video slot (newer and faster, but no real benefit yet) or an AGP 8X slot. Are you a hardcore gamer or someone who just uses a PC for a little email and word processing every now and then? This is the major question that’ll tell you the video card you need. Obviously the more intense and rigorous your video and graphics demands, the more video memory your card will need.

4. Memory. Memory or RAM (Random Access Memory) is easy too. The main size ram you’ll find that goes with what’s still the most common new computer motherboard size (the Pentium compatible, socket 478) is the standard DDR 184 pin memory stick. Whether you need DDR 333, DDR 400, or DDR 533 (mhz, frequency and speed really) depends on the board you chose. Some handle all of them, some handle just a few, so be sure to read that part of the box, (or online description).

5. Sound Card. This is probably one of the easiest parts to pick out and add. Most standalone sound cards you’ll see out there (the best way to go) are pretty good in the digital sound that they’ll give you. I would go with Creative Labs, who I mentioned earlier, because they’ve been around since the mid 80’s; they’ve got this right. Almost every one sold and made today is the PCI slot, the most common motherboard slot, so it’s pretty hard to pick a sound card that won’t work.

6. Hard Drive. This is your main storage on your PC. It holds all of your files, games, pictures, operating system, everything. I would make sure I had at least 160 gigs of space, even if I weren’t a power user. This sounds like a lot but you’ll find that just in everyday PC use, that space gets eaten up fast. There are a few quality names out there that most people know, like Western Digital and Seagate.

7. Chassis / Computer Case. It’s good idea to get a case that comes with the power supply already in it, so you won’t have to deal with the annoyance of buying one separately and fitting it in. Plus, the power supply warranty (and they do go out sometimes) is by the same people who made your case, so they’re easy to track down. The only big consideration is that you need to get a case that supports the new generation boards (socket 478 and 775 for power users) because the power supply has this special 4-pin plug that any motherboard made in the past 5 years needs or it won’t even boot up. But still, the biggest part of your computer case selection is going to be cosmetics and personal style, so pick one you like!

8. Other Drives. Once the main parts are together and your system’s up and running, you can pick and choose what extras you like or need – everything from CD or DVD burners to MP3 hubs and advanced audio hookups.
With a little smart shopping, and little close attention to quality brands, you can build one affordable, high-performance PC in a snap!

Phil Moyers, owner of Build Your Own Computer Plan shows computer novices how to save a ton of money by putting together fast, high performance PC’s of their own with handpicked, quality parts.

MCSE stands for Microsoft Certified Systems Engineer. What is this term, really? While the term sounds like a degree that you would get in Microsoft, it is not really an engineering degree, per say. In fact, that is one of the biggest complaints about this learning process. Nevertheless, MCSE is a training course of sorts that is designed to teach individuals who want to learn how to handle various aspects of Microsoft skills. The goal is to have a group of people who are knowledgeable in the areas that Microsoft is specific. Let’s explain.

Microsoft developed this type of training to allow individuals to get a specific training course, or several in various types of skills that pertain to Microsoft. The thing about this training is that it is specific to Microsoft. While you may learn to install a program in another course which would teach a broad range of information about all ways in which to do so, in the MSCE, you will learn strictly how it is done through Microsoft.

So, How Does MSCE Work?

In most cases, the training can be done in several ways. Students can take classes through certified teachers in school or they can study on their own. Some individuals feel that they have enough experience in the various uses of Microsoft to be able to take the test without taking a training class. The test is given at specific areas at specific times. In order to be considered, you must pay a fee of about $125 for each of the tests and certifications that you plan to take. The tests range in knowledge levels and in most cases, it is wise to take the training courses for MSCE prior to taking the test as it can be quite challenging.

You will find more information about MSCE throughout the web.

What are the best things to look for when you’re shopping for IT training? This article gives you five surefire ways you can tell if your IT training will be the best it can be – before you spend any money!

1. Try Before You Buy. Request free samples of the training if possible, so you know what you’re buying before you get it. Make sure that the content you’re getting will give you the training you need.
2. Check the Content. Most training only focuses on exam knowledge. This type of training won’t help much on the job because it doesn’t teach you how to apply your certification in the real world. Also, be wary of training that’s nothing more than a thinly-disguised electronic copy of a book. This training is a high-cost alternative that doesn’t give you more than you would get by reading the book yourself.

   The best training will give you complete certification knowledge, then show you how to apply that knowledge on the job to do your work successfully.

3. Research the Company. Look for customer comments on the training company’s website, brochures, etc. Also, do a Google search to see what customers have to say when they’re not being featured in promotional material.
4. Look for Engaging Training. Compare the free samples you’ve found: which are engaging and easy to learn from? Because training can be a long process, you want an instructor that holds your attention, gives a great learning experience, and delivers tons of content without sounding like they’re reading from a textbook.
5. Find Training That Works For You. There are many types of training out there, such as books, classes, sample tests and videos. Books are usually the cheapest option, but they can be hard to follow and many people find themselves easily distracted when studying with them. Because classes are instructor-led, they can be engaging and easy-to-follow, but they can be very expensive and inconvenient. Sample tests often only determine if you know the material or not, and are better used to test the knowledge you have than for actually learning.

   Training videos are a great option for many people because they are instructor-led and easy to follow. They are a cost-effective alternative to classes, plus they’re very convenient, allowing you to train on your own time and to keep the content so that you can use it as an ongoing reference.

How can a super small garage type start-up company with just a good idea and some brains launch put together a team of seasoned entrepreneurial know how to launch a new product. Well one idea is stock options. Recently I was asked to assist a small entrepreneur with a project, which would eventually turn into a new personal tech product. The company had no money and could not pay me for my knowledge. Indeed I had known this an not asked for anything. Yet the young entrepreneur said to me; “I request that you must accept some type of financial comp from this venture. Stock options, etc, etc.”

Realizing of course that this was a sincere gift of goodwill and also showed a level of integrity, which is rare I replied

“I am not interested in money really, but I also realize that it is fair thing to do and in the long-run best for all concerned. I would accept stock options, but that is entirely up to you. I am not requesting anything to assist you, but I would like one of these devices once perfected and an additional strap to mount it on a Mountain Bike. I believe this is one of the coolest little gadgets I have ever heard of.”

It was therefore agreed and it solved a simple problem, a garage start-up generally has limited funds you see? For me, well I am mostly into the challenge of winning. This product can do a lot of things and the possibilities are endless meaning as long as the entrepreneur will walk before he runs then he should be able to look thru all the other doors as he goes later on down the road and see which ones might make sense in the future to for his little growing start-up company to go thru.

You see his little personal gadget is a product that would make sense for security professionals, space endeavors, healthcare costs, decreasing domestic problems, dietary issues, protection of our people, landfills filled with batteries, industry, you name it. We must understand that even a simple little high tech gadget can make a huge difference and really become something some day.

Indeed anytime you can have that level of impact on a civilization you indeed deserve a percentage of some of the efficiencies that you bring to the table. Bill Gates for instance, deserves his cut of the efficiencies he has brought to the World. So therefore taking stock options might be a really good way to recruit the people you need early on to really make one hell of a company. Think on this.

As man learns to make machines that no longer rely on animal
or human power, he finds that he has to develop some means to
manage and control them. Powerful machines let loosed by
themselves will create havoc and destruction.

Control systems have been developed for machines or processes
so as to reduce the chances of failure and to provide the
required results.

Basically, there are open loop control systems and close loop
control systems.

Open loop systems are those where the controller action is not
related to the final result. This means that there is no
feedback to the controller to adjust the control action. A
simple example is when you fill up a tank using a garden hose.
As long as the tap is opened, the water will flow. The height
of the water in the tank will not make the tap close.

However, when you see the tank becoming full and decide to
close the tap, you are adding the element of feedback to the
loop. It then becomes a closed loop. But it is a human
controlled closed loop.

Closed loop systems use feedback from the final result to
adjust the control action accordingly.

But how would you like to stand in one position, watch the
process going on and operate valves, or switches according to
the conditions you want? This is very tiring, isn’t it?

Moreover, human beings are prone to fatigue, boredom, and
misjudgment. Manual control works very well only if the speed
of the response is very slow, and the result is not very
critical or important. Human controlled systems can become
very unreliable.

Machines are made to replace humans in most control systems
today.

The basic feature of any control system consists of 4 elements.
These are the measuring element, the controlling element, the
set value, and the correcting element.

The measuring element provides a means of detection/measurement
of the conditions required. This is the “eyes” or “ears” (or
other senses) of the system.

The controlling element is the place where all the decisions on
what actions to take are being made. It can be considered the
“brains” of the system. It must make decisions based on certain
guidelines or values required. The set values are inputted into
the system by humans.

The correcting element is where the correction to the process
is done. It can be considered like the “hands” or “feet” of the
system. It must take certain physical actions to bring the
processes back to the set value.

Well folks, be in control!
