Inside a Computer - Computer Components

Computer the best machine that helps to solve the longest calculations and has automated the most tire some processes is build up of the basic components such as a central processing unit, disk drives, keyboard, monitor, mother board and other such important components that functions parallel with each other. The functions of each of these basic components are different and are very important for proper functioning of the computer that ultimately proves useful to us. Computer system consists of input and output devices, however he basic components of a computer system are:

Central Processing Unit - Concisely known and understood as the CPU, this unit is the brain of any computer system. A computer system cannot exist without the CPU and this is because it contains all the sub basic units such as the arithmetic unit and others that performs all the mathematical and other operations.

Computer

Motherboard - This is the part of the computer to which all the hardware is connected to. It consists of processors and other sub processors that perform very important memory related operations. There are various kinds of motherboard available depending on the configuration of computer system required.

Random Access Memory - This part of the computer system also widely known as RAM is connected to the motherboard. As quite obvious from the name itself, RAM stores the data temporarily and the data stored also can be accessed from RAM. Data from here can be moved to a permanent storage such as compact disks and hard disks.

Monitor - This is also considered as the most versatile and important part of a computer system and is one of the output devices. This is the part where user can see and input the desired results and data to the computer. The various operations that are desired and the result of any mathematical calculation can be viewed on the monitor. In short, this is the user interface through which the user and the computer can communicate to each other.

Keyboard - Keyboard is an input device component through which a user can input the data and this data can be of any type depending on the type of input. The use of keyboard can be varied depending upon the type of use. For example it can also be used as a gaming device while playing games etc.
Hard Drive - The data that was stored temporarily in the RAM can be moved and stored in the hard disk drives. The size of the hard disk drives can be varied depending upon the use and the requirement of the user.

Disk Drives - These can be considered to be an optional component of a computer system. If a user needs to read a data from a floppy drive, USB drive or a compact disk drive then disk drives can be installed, again depending upon the use and requirement of the user.
The above mentioned components when assembled properly forms a computer system that can be used for various purposes such as basic office record keeping, surfing internet, communication, automation of works etc.

6 Tips To Best Computer Buy

Buying a new computer can become a tedious task these days as many of us tend to get confused or simply don't know how to choose the best computer from the wide range available. Here are 6 tips to best computer buy:

1. The first and logical thing to do is determine exactly where you will be using your computer from. Do you plan to use it at home, or do you travel with business often? After you answer this question you know if you want a desktop computer or a notebook.

Computer

2. The next thing to do is determine your budget. There is a wide range of both desktop and notebook computers to choose from so they can cover any budget. Desktop computers can cost anywhere between 0 and 00 (Note that many sites don't list the monitor in the cost, so read carefully before clicking the checkout button), while notebooks between 0 - 00+. Decide on how much money are you willing to spend and continue to the next step.

3. Now it's time to determine what will you be using the computer for. Are you buying it for your kid to play video games, watch movies or do you plan to use it for work or internet surfing? Of course you can buy a computer and use it for all of those things but for example if you plan to use it just for business then you needn't buy a computer with the best video card on the market.

4. Are you going to store photos, Microsoft Office documents, mp3 files, video files etc.? You need to think about this to determine what hard drive your computer needs. If you'll be using it to store photos and Office files then you need something in the range of 60GB but no more. If you plan to store many video and audio files then a 220GB hard drive would be more appropriate.

5. Another very important thing to consider, which many people overlook, is how often do you replace your computer? This is very important because most new computers come with a special OEM license for Microsoft software. As this license cannot be used on any other computers, if you change your computer often then it would be a waste of money to buy each end every one of them with the software and pay for it every time. If you change your computer often it would be wise to purchase a retail copy of the Microsoft software and save money.

6. Buy a ready made computer or create your new computer by selecting all the parts yourself? In my opinion, if you're a person who changes their computer often then buying a ready made one is the perfect choice for you. If you don't plan on changing the computer then it would be wise to create it yourself at a local store or even on some sites on the internet. This is because all the big computer companies use proprietary components and if you buy a ready made one it is usually harder to upgrade later.

This problem is extremely stubborn and will keep happening time and again whenever you are working on something important or playing games. But how to stop your computer from freezing?

To stop your computer from freezing, you need to know the causes of the problem first. There are two major causes of the freeze problem. The first common cause is that you run too many programs at the same time. RAM resource is limited when you start a dozens of programs on your computer. Each program will fight for RAM. And then your computer runs out of every single bit of you RAM. So it would freeze up because there is no RAM left to execute a single task.

Computer

The better way to avoid this situation is to update your RAM or not to run many programs at the same time. But in another case, your RAM usage is lower than 100% and you run only one or two programs at a time, your computer still freezes up randomly. How come this happens?

That must be caused by your registry. Yes, it is. Some people just upgrade their RAM to 8 G or higher when they come up against freeze/lockup problem. But unfortunately, many of them are still bothered by it. They don't know registry errors are the real troublemakers.

Registry is one of the vital parts of Windows system that contains vital information. The information in it tells your computer how to implement every task, including how to start and shut down, how to run a program and so on. But registry is very easy to damage by many matters, such as improper install and uninstall of program, incorrect operations by you, virus, malware and so on. When your computer runs over time, your registry is loaded with errors and incorrect information. Consequently, your computer starts running slow and freezing frequently.

Define Computer Hardware

It is quite well known that the working of the computer is pulled by hardware and software. One can define computer hardware as the electronic, magnetic, and electric devices that carry out the computing functions. Hardware is the physical components of the computer like microprocessor, hard disks, RAM, and motherboard. The peripheral devices such as monitor, mouse, keyboard, printer, and speakers can also be included in the list of hardware parts. The programs that run on the computers like Windows, C++, and Photoshop are the software parts of the computer. A good example for an easy understanding of hardware-software definition is music CDs. The actual compact disk is the hardware, while the songs and music in the CD are the software parts.

There is another way to define computer hardware. Hardware devices are the executors of the commands provided by software applications. For example, let us see what happens when you click the print button of the web browsing software. The software application provides a command to the processor, which is the central part of all computer hardware. Processor in turn checks for an attached printer. If the printer is ready, the software will get a positive response from the processor. Then the software application provides instruction to the printer via the processor to print the web page. In that sense, hardware parts are the foot soldiers and software applications are the commanders in the digital operation that takes place within a computer.

Computer

The main player of computer hardware is undoubtedly the microprocessor. It is the sun in the solar system of computer hardware devices. It is the central component and all other components work around it. It is an integrated chip on which a number of functions are incorporated. Two specifications determine its efficiency. One is its processing speed, which is measured in gigahertz. The other is its bit rate. Commonly available processors are 32 bit and 64 bit. The bit rate is a measure of the efficiency of a processor to carry out multiple operations at the same time.

One cannot define computer hardware without mentioning the two types of memory used in computers. One is permanent memory. It refers to the magnetic storage capacity of hard disk. It is measured in gigabytes. The second is RAM or random access memory. This memory is able to store data only when the computer is switched on. The memory will lose all the data when the computer is switched off.

Another important product that one should mention when one defines computer hardware is motherboard. It is the electric and electronic circuit board on which all the other components are inserted. There are several other kinds of products such as sound card, video card, network card, and modem that complete the hardware spectrum.

Why Does My Computer Keep Freezing?

I'd take a wild guess that at one point or another, you've called a friend and asked them "Why does my computer keep freezing?" More people than not have experienced their computer freezing up on them. It's not a fun thing when it happens, and getting it fixed quickly is certainly at the top of your list of priorities. The longer the freeze lasts the more chance there is for further damage to your computer. This is why finding out what's wrong, and fixing it right away, is so important.

Did I Make My Compute Freeze?

Computer

If you're wondering if it was your fault that your computer froze up, join the club. Everyone thinks they've done something wrong, and the result is that their computer freezes. More often than not it has absolutely nothing to do with you. If you did play a role in it, it was probably because you opened an infected email or downloaded something from an unsecured website. In any event, your computer is freezing and it needs to be fixed.

What Might Have Caused The Problem?

Sometimes your computer freezes because it's been infected with malicious programming. Removing this will clear up the problem. It could be that a program that you recently loaded onto your computer is the culprit. Sometime a new program doesn't sit well with the ones that are already on your computer, and as a result, your computer freezes. There are actually a whole bunch of different reasons your computer might be freezing up on you. Computers can freeze for common reasons, and the most common is that something has happened to your computers registry.

Can My Computer Be Fixed?

Once the shock has worn off, and it has become quite obvious that your computer is somehow messed up, the next question is usually whether or not you can get it fixed. Most times the answer is yes.

Every computer has a registry. This is where all the vital information that allows your computer to function is stored. The information is in the form of files and entries that are, unfortunately, susceptible to damage. In the majority of cases of computer problems, the registry has been compromised somehow and needs to be repaired. The good news is that it can be repaired.

Preventing Your Computer From Freezing Both Now And In The Future

There is a piece of software called a registry cleaner that can solve your freezing problems, and quickly. This type of program will scan every inch of your computers registry and find the problem. It will fix it for you also if you want it to. Considering that each time you encounter a problem with your computer the answer lies somewhere in your registry, this is a valuable tool to use when trying to find the problem and fix it.

A registry cleaner is quick, efficient, and affordable for any budget. If you're wandering around your home or office mumbling to yourself "Why does my computer keep freezing?" then you need to get yourself a registry cleaner and fix the problem once and for all.

Diagnosing Bad Computer Memory

Sometimes when your computer starts acting "funny" it can be a sign the memory is damaged. The good news is memory for computer systems is inexpensive and easy to replace.

Why Does Memory Fail?

Computer

When compared to other components, memory for computer systems has a very low failure rate. It has no moving parts, unlike a hard drive, and isn't subject the heat stresses the processor or video card are. However there are a number of problems that can damage memory.

Static electricity is a common culprit. If you were in there replacing some component and forgot to discharge static from your hand just one time, you might have sent an electric shock too weak to feel but strong enough to damage the delicate microcircuitry. However even if you have never had the case open, there are other possible causes.

A power surge can damage memory for computers. Some people expect a surge will be dramatic, with sparks and smoke, but in fact it can cause subtle damage that may take days to show up. Even if you have a surge protector, you still might have "dirty" power, which is electricity with unsteady voltage. This is especially true in older buildings. Finally, dust can get inside the case and short out memory contacts.

Signs of Bad Memory

Trying to diagnose computer problems can be frustrating since there are so many components that could be the cause. Software, viruses or a faulty Windows installation could be at fault as well. Failure of memory for computer systems has some distinct symptoms that stand out.

The infamous Blue Screen of Death (BSoD) is often a sign of hardware problems. If your computer locks up with a blue screen containing cryptic messages, this is a BSoD. If it happens just once then it may just be a fluke, but if it happens repeatedly that points to serious problems. Spontaneous reboots or system freeze can also indicate hardware problems.

An important question is when it happens. If it happens only when playing certain graphic-intensive computer games, that could be a sign of a memory problem. BSoDs or reboots during other memory intensive operations such as compiling software, video editing or viewing large images also are symptoms of memory problems.

Testing and Fixing The Memory

There are a number of utilities that can confirm the existence of memory errors, such as Microsoft's Windows Memory Diagnostic. By running a memory test utility, you confirm the error is actually in the memory and not some other component. By removing all memory modules except one and testing each one in turn, you can isolate which module is the problem.

Once you have confirmed the memory problem, replace the damaged module. Reseating the memory module may fix the problem, but this is often temporary. If the module is damaged, it should be replaced. Memory for computer systems in inexpensive, so don't take the chance a damaged module could corrupt important data.

How to Speed Up a Sluggish Computer? Here Are Solutions For You to Speed Up Your PC

Do you want to speed up your sluggish computer because of its lower-efficiency? In my opinion, every one wants to work with a computer which runs fantastically fast. Here are some solutions that you can do in daily life to speed up PC if you do not want to reinstall or pay too much to upgrade hardware.

First, do not run too many programs at Windows startup. Lots of programs load at once when booting up the computer will make the computer run desperately slow because of the insufficient system resources and memory. Go to Start, Run, type "msconfig" and press "Enter" to access System Configuration Utility, check "Startup" tab and uncheck the programs that do not need to run at Windows startup.

Computer

Second, do not use the ActiveDesktop. Otherwise, the system will run extremely slow. Open Group Policy by typing "gpedit.msc" within "Run" ->User Configuration ->Administrative Templates -> Desktop -> locate and disable Active Desktop.

Third, reasonably set the virtual memory, which always affect system's and applications' reading speed. So do remember to set the size of the virtual memory as three times of machine's own memory, for example, if your memory is 32M, and the virtual memory should be 96M. This can be set by following the steps below: Start -> Control Panel -> System-> Advanced -> Performance -> Settings -> Advanced within the popping-up window -> "Change" next to "Virtual memory".

Fourth, to speed up your slow computer, you should regularly run a disk defragmentation. After being used for a much longer time, numerous file creation, changes and deletion will result in many intermittent sectors, which causes the non-continuous files on the hard drive. In this way, the hard disk head has to move too much when trying to read/ write related data. This will greatly make computer run sluggishly. By defragmenting the hard disk, all non-continuous files will be rearranged and placed close at the same place. It is recommended that you should defragment your computer once a week if possible.

Fifth, regularly repair registry errors. Registry is the most important component for system and applications installed on the computer. They will run improperly if there is something wrong with the registry. Besides, registry errors will always result in system sluggishness, freezing and random crashes. So to successfully speed up your PC, you should have a trusted registry cleaner in hand in order to repair the invalid, corrupted registry entries.

How to Speed Up a Sluggish Computer? Here Are Solutions For You to Speed Up Your PC

In conclusion, even though there are kinds of solutions to speed up PC, with a good habit of computer usage in daily life, you can always enjoy a faster computer. If you find that your computer runs desperately slow, do remember to regularly optimize Windows registry.
