What Are the Main Components of a Computer System?

We all know that computers are complex devices, machines made out of an amalgam of electronic parts and components. But which computer components are essential for a computer to run? Modern PCs can still function fully without Bluetooth or a floppy disk drive. Here is a list of computer components that a computer system cannot do without.

What Are the Main Components of a Computer System?

* Motherboard

The motherboard is a very basic unit in any computer system. This is the computer component to which all other internal computer components are attached. It links all the other main components of a computer system together. Consequently, motherboards are sometimes referred to as the "heart" of a computer system.

* CPU

The centralprocessing unit or CPU is the computer component responsible for running programs and applications on the computer. Without a CPU in your computer, you will not be able to do any tasks--you cannot boot to an operating system, you cannot play music, videos and games, and you cannot do any word processing. For a computer to function, it has to have a CPU.

* RAM

Random Access Memory or RAM is another vital computer component. It is the storage Media where a computer temporarily stores files and information that it can pull at random when running programs and applications. Together with the CPU, RAM determines the computer's speed. A computer with a large RAM and a mediocreCPU can actually run faster than a computer with a Powerful but low CPU RAM.

* HDD

As opposed to the RAM, the hard disk drive or HDD stores computer files and data long-term. Even without Power, the hard drive still retains the files stored inside it. The hard drive can store important system files like the operating system, program files and other data. It can also be used to store mp3s and videos. If the computer runs out of RAM, it will temporarily use the hard drive as virtual memory bank.

* Video Card

A video card allows a computer to display images on the computer monitor. It helps speed up the rendering of images onScreen and contributes to clearer and detaiLED pictures. PC gamers andMultimedia software users will find a high-end dedicated graphics card helpful in running graphics-intensive programs smoothly.

* PSU

The power Supply unit or PSU supplies all computer components with power. It converts the high voltages from an AC power outlet to lower voltages that are safe for internal computer components. Without a PSU, computer and its components will not be able to power up.

A computer can also benefit from an optical drive to read and play CDs and DVDs, a network card and router for connecting to the Internet, and peripheral devices such as Printers and scanners. The motherboard, CPU, RAM, HDD, video card and PSU are, however, the main components that make up a computer system.

Latest Technology in Computer Hardware

The rate at which new computer hardware products are arriving in the market is simply mind boggling-. As the technology advances, the size and the price of the devices come down, while the efficiency and capacity increase. The scenario is the same in all cases, whether it is about internal components like processors, motherboard, RAM, graphics card and hard disk or for peripheral accessories like mouse, keyboard, and monitors. Personal computers became popular only before about three decades back. But already there are huge piles of outdated and antique hardware components and devices. This is a tribute to the tremendous rate of development of latest technologies in computer hardware field. Perhaps, the newest entrant into the archeological catalogue ofcomputer peripherals is > CRT monitors. The sleek looking LCD monitors are spreading like computer viruses.

Data storage devices have attracted considerable attention of the technology developers. New kinds of storage devices such as newer versions of flash memory cards, hard disks using latest technology and disks of ever-increasing capacity are the results of advancement in latest technology in compute hardware. The memory size of the random access memory (RAM) cards is soaring to enable the smooth functioning of graphics animation software packages and streaming video websites. Also, computer motherboards have undergone substantial changes over the years. More and More functions are being added to the motherboard. Also, despite theincredible improvement in performance and functionalities, the price of these components has actually fallen steadily.

The most vital component of a computer is the microprocessor. It is in this field that a battle of latest technologies in developing computer hardware takes place. The pace of development of microprocessor increases as the competition between the major processor chip manufacturing companies, Intel and AMD, intensifies. Both the companies are engaging in a neck and neck competition and continuously outdo each other in introducing new technologies.

The error will be a reflection of low memory problems with RAM or Virtual memory. Often, this error can be easily reversed by freeing up memory for your system's use. This article will show you to speed up your memory functions with just a fewclicks.

Before you begin freeing up memory, you must test to see if your low memory error is being caused by faulty RAM hardware. If the RAM hardware has be damaged, it may need to be physically replaced. Follow the instructions below to test your memory.

2. Click "System".
3. Click "Advanced System Settings"
4. Under Performance, Click "Settings".
5. Under "Visuals Effects",
6. Choose "Adjust for best performance".

As previously stated, programs need memory. There is no way around this fact. If you have tons of programs running silently in the background, these programs are silently creating low memory environment. When Windows loads, it also loads start up programs. Eliminating startup programs is one of the best ways to end low memory errors. This tweakwill also speed up your shutdown process. You can cut your start up programs load to bare bones by altering your "msconfig" also known as your start up program configuration. Here is how:
