There are several components within a computer that help make it faster and more powerful. Below is a list of the main hardware components that help contribute to the performance of a computer. Keep in mind that even the software running on the computer may impact the speed of a computer.

Processor (CPU)
Computer CPUThe overall speed or clock speed of the computer and how fast it is capable of processing data is managed by the computer processor (CPU). The computer will be much faster and more powerful when it is capable of executing more instructions every second. For example, the first computer processor was the Intel 4004, which was only a 740 kHz processor and capable of processing approximately 92,000 instructions per second. Today’s processors are multi-core GHz processors capable of processing over 100 billion instructions per second.

Although today’s computers can execute billions of instructions every second, the processor is usually waiting for those instructions from the slower types of memory in the computer. Because RAM and the hard drive are slower than the CPU, computer processors and motherboards use cache to transfer data between the processor, memory, and components in the computer. Cache is the fastest type of memory and a computer with more L2 cache or L3 cache is capable of storing more instructions and send those instructions to the processor more efficiently.

Memory (RAM)
A computer with more memory (RAM) will be capable of storing more programs that are currently running in memory. If your computer runs out of memory, the computer must swap unused data stored in memory to your hard disk drive until it is needed again. By adding this extra step and because the hard drive is the slowest type of memory your computer can become much slower if it does not have enough memory.

BUS speed
The bus speed of the motherboard can increase or decrease the speed at which data is being transferred between all the hardware components in the computer. For example, a Front Side Bus (FSB) of 66 MHz is going to be much slower than a 400 MHz FSB. If the computer has a slow bus, the processor has to wait longer for the instructions, which makes the computer run slower.

Hard drive
Crucial SSDThere are several components of a hard disk drive that can make it slower or faster, which makes your computer run slower or faster overall.

For example, a hard drive can cause a computer to be slower because of the moving parts inside the hard drive, which results in slower read and write times from and to the hard drive. However, a newer and faster solid state drives (SSD) have no moving parts, which results in faster read and write times from and to the hard drive.

Below is a list of different factors that contribute to the speed of a hard drive.

  • An SSD drive has no movable parts, which makes it much faster than a traditional HDD.
  • Older computers use EIDE (ATA) cables and ports to connect the drives, which have a much slower transfer rate than the SATA cables and ports used in newer computers.
  • The RPM of the HDD is how fast the platters inside the hard drive spin. A 5400 RPM hard drive will be much slower than a 7200 RPM drive.
    Since cache is the fastest type of memory, a hard drive with a larger cache allows data to be handled more efficiently when it’s transferred between the computer and the hard drive.

Video card
If you play the latest computer games, a powerful video card with its own CPU (GPU) and its own memory makes the game run faster. These types of video cards help with the performance of the computer by taking on the responsibilities of processing the 3D rendering and other complex tasks. The more powerful the video card is, the better it can render the 3D graphics and the faster it can handle the overall processing of graphics for the game.
The interface of a video card is also a contributing factor to the performance of the video card. For example, older AGP video cards are much slower than newer PCI Express video cards.

Tips for Speeding Up Your PC
Few things are as frustrating as dealing with a slow, sluggish computer. When a computer is brand new, it works wonderfully well. Over time, though, its performance can slowly begin to worsen. This happens for a number of reasons, but the biggest culprits are things like spyware, adware and other computer threats that are unwittingly downloaded along with other content while online. You don’t have to download thousands of MP3s, movies or other items to experience these problems, either – nobody is immune to them. Instead of accepting the situation, there are plenty of techniques and strategies that you can use to make it better – a few of the best ones are outlined below.

Strategy #1: Clean Your Computer’s Windows Registry

The biggest cause of slow, sluggish PC performance is errors and problems within its Windows registry. Adware, spyware and other threats usually target the registry, damaging or misplacing important files within it. When it comes to PC cleaning, a daily Windows registry cleaning should be at the top of your list of priorities. However, this should never be done manually – there are too many opportunities for major errors that could seriously damage your PC’s operating system. Instead, invest in a high-quality Windows registry cleanup program and configure it to run once per day – you won’t believe the difference that it makes.

Strategy #2: Remove Unneeded Files
Every time you log on to the Internet or otherwise use your computer, temporary files are generated. They are usually only needed once; however, they don’t disappear on their own. Instead, they accumulate over time until they are cluttering up your computer’s file system and affecting its performance. While it’s possible to remove these files one-by-one, it’s much easier and quicker to use a PC cleaning tool that’s designed for the purpose. Try to do so about one time per week to keep your computer humming along with ease.

Strategy #3: Remove Unneeded Programs
Like many people, you probably download and try out many different programs each month. How many of them do you actually end up using on a regular basis? Chances are, not very many of them. By getting into the habit of uninstalling unused and unneeded programs, you can keep your computer’s file system a lot less cluttered. In turn, your PC’s performance will improve dramatically. You can optimize your computer in this way by using its Add/Remove Programs feature. Its location varies by operating system, but you should be able to find it somewhere in the Control Panel.

Strategy #4: Empty the Recycle Bin

When you click “delete” on a file or a program, it doesn’t go away for good – not immediately, anyway. Instead, it sits in a kind of purgatory in your computer’s Recycle Bin. As things pile up in the Recycle Bin, your computer can start exhibiting some very annoying problems. If sluggish startups and frequent crashes are occurring with increasing frequency – and your computer’s recycle bin is very full – go ahead and empty it. From then on, get into the habit of doing so about one time per week. This small but important strategy can make a huge difference.

Strategy #5: Perform a Disk Defragmentation

Windows isn’t very efficient when it comes to storing files. It actually splits them up, depositing them into whatever spaces are available. The more spaced apart the pieces of a file are, the harder your computer has to work to make them run. The Windows disk defragmentation system tune-up utility works to piece all of those files back together again. The process is a long one, though, and only needs to be done about four times per year. Set it up to run automatically once every three months. By doing so, you’ll be able to keep your computer running in tiptop shape.

When it comes to keeping your computer running optimally, small but regular maintenance is the best way to go. Protecting your PC only does so much; even the most careful Internet users in the world unintentionally download malicious software from time to time. By using basic system tune-up tools, cleaning your computer’s Windows registry regularly, performing regular file-cleaning maintenance and otherwise optimizing your PC, you should be able to keep it in like-new condition for a lot longer. Even if your computer has been performing slowly for some time, beginning this regimen is sure to produce results. In the end, you’ll be able to enjoy a computer that flies along – instead of one that spins its wheels.

Computers have become a staple of our world, continuously undergoing development, changes and updates. There are pretty a lot of things that we can do with them. A huge part of computer usage comes from personal computer usage. People type, chat, surf the net, watch shows, download files, play games and do a lot of other things in the computer.
People utilize the computer to surf the internet which successively endangers it to a number of unwanted and harmful programs, and viruses. System maintenance is essential to make certain that it is working properly.
The computer system is not so much different from our automobiles regarding maintenance. Just like our engines, we perform typical structure check-ups or bring them to special service outlets to get fixed. Aware of the computer’s significant part in our office and daily life, we should constantly make sure that there are no unwanted matters that could alter or cause it to break down.
Two Kinds Of Maintenance Computers Go Through:

Preventive Maintenance.
Preventive maintenance includes common computer security and cleanups that prevent potential PC errors. Simple actions like scanning, virus removal, disk defragmentation, disk error correction and file organization are applied. Preventive maintenance also includes motherboard and other components clean up to prevent related problems.

Corrective Maintenance.
While preventive maintenance’ devotion to keeping the system safe from potential technical problems, corrective maintenance’ devotion is diagnosing and fixing existing problems. Corrective maintenance may require repairing parts or even replacing them with new ones. Computer technicians are specifically trained to carry on repairs and configuration assistances, but it is likewise advisable to visit computer maintenance or repair centers that are knowledgeable with the type of operating system or computer.
Scheduled computer maintenance is important to guarantee that it is secure and is functioning properly, especially for businesses and organizations that bank expectantly on computer networks. Finding an adept computer and IT professional is priceless in ensuring that the actions and important data stored in the communication systems will not stolen nor leaked. Computer maintenance and assistance providers help your organization increase its productivity.

Defragmenting your computer’s hard drive is the equivalent of keeping your dresser drawers organized. (Eg. Can you tell that we love using clothes and closet references?) If you love clothes as much as we do, you probably like to know where each of your favorite items is at all times. This is why you have dresser drawers dedicated to similar items of clothing: socks and undies in one drawer, tank tops and t-shirts in another drawer, sweatshirts and sweatpants in another drawer, and so on.
Imagine how hectic it would be trying to put an outfit together if you didn’t have specific drawers dedicated to like items and instead simply threw clothes in random drawers just to get them out of the way? It would probably take you twice the time to get ready in the morning (oh, the horror).
Your computer’s hard drive works in the same way. Generally, similar items are grouped, or written, together on the hard drive, making it easier for your computer to locate the information it needs to run a program or perform a task. But over time files can become fragmented or separated—thrown into random dresser drawers. When this happens, it takes your computer longer to scan the hard drive to locate those blocks of information it needs to perform a task, which decreases the computer’s speed and performance.
That’s where defragmentation comes in. When you defragment the hard drive, your computer regroups those similar items together again, which allows your computer to locate what it needs faster, subsequently speeding up response time.

How do I defragment my hard drive?

If your computer is making a lot of noise or running extra slowly, it could mean that it’s time to defragment the hard drive (or simply “defrag” in industry lingo). To defrag your hard drive:
Go to the Start Menu

  • Click on “My Computer” or “Computer”
  • Highlight the C: Drive, but do not double-click on it
  • With the C: drive highlighted, right click the mouse
  • Click on “Properties”
  • Click on the “Tools” tab
  • Under Defragmentation, click “Defragment Now”
  • Depending on how long it’s been since your hard drive was last defragmented, the process could take anywhere from 15 minutes to several hours. You will not be able to use your computer during this time, so you might want to defrag right before bedtime. By the time you wake up, your computer’s hard drive will be neat and tidy!

The Random Access Memory modules inside a computer store temporary data for the Central Processing Unit. Data that cannot be stored inside the RAImportance of RAM and Speed
The Random Access Memory modules inside a computer store temporary data for the Central Processing Unit. Data that cannot be stored inside the RAM must be accessed from the hard drive, slowing down the machine. More RAM means that more programs and larger files can be used simultaneously without any impact on performance.

How RAM Works
Computer RAM is used to store information that the system needs quickly. This includes open files and data related to open programs. Running several programs simultaneously, running one or two complex programs, or opening up a series of large files (such as photos or videos) can quickly fill up the available space. Once the RAM is all used up, the hard drive must be used as a replacement. As data cannot be loaded from the hard drive as quickly, tasks such as opening programs and files take longer to complete.

How RAM Affects Performance
The RAM does not change the speed of the CPU. Nor will adding more RAM necessarily speed up your computer. However, your computer will slow down whenever the RAM is full. Therefore having as much RAM installed as possible is important for maintaining the performance of a system. Working with larger files, working with complex software (such as video editors and games) and running many programs at once all require more RAM than average day-to-day tasks. Browsing the Web, working with smaller documents and checking email require only a small amount of memory.

Upgrading RAM Modules
Upgrading RAM in a desktop computer is a relatively straightforward process. Existing RAM modules can be replaced, or you can add additional ones. The module slots are typically located close to the CPU socket. Consult the motherboard manual or manufacturer’s website for details of compatible RAM modules that will work with your system. Once new modules are purchased, they can be slotted into place by applying firm, even pressure until the plastic holders snap into place. The system must be turned off and unplugged from a power source before RAM is fitted or replaced. Installing RAM inside a laptop is more difficult because of the smaller spaces involved, but some manufacturers do allow access to the module slots.

Your computer might not come with as high of a price tag or as many moving parts as your car, but laptops and desktops require just as much regular maintenance to keep running efficiently and securely. Desktops come with lots of peripherals that need regular upkeep and cleaning
