Computers today are a very important piece of equipment used by 90% of the population, whether it is in business or at home they have become a must for almost every one. Computer knowledge is increasing as anyone who has one wants to know how to use it effectively. Computers or PCs are systems are designed to be used on a regular basis, but unlike laptops or mobile, they cannot be easily carried everywhere. It is a system that is fixed in a single place due to the huge amount of components within.
Separate screens and keyboards are available with Desktop computers. The display screen on top to save space that is used a workstation which is used in earlier models. Some early models were almost as big as the room they were located in and absolutely huge. Then its size is reduced after the evolution of minicomputers and making them more like the size of refrigerators. It was not until the late 90's that the size of a single number on the workstation. The fully programmable workstations and HP 9800 were among the top teams fully programmable desktop size to be invented.
In turning them into fully programmable workstations the components played a very crucial role. Within the workstations the motherboard plays the most important role and the mother board is the backbone of the PC because the use of the motherboard decides that what kinds of components are to be used for the PC and processor also becomes the heart of the desktop computers. The speed of the system consists of processor because High processor speeds increase the speed of the computer and helps in getting the work done at a faster. It is assumed to have a processor with a high speed as it gets the PC running fast. The speed of the processor is measuring in Gigahertz.
Memory is the device which plays an important role in running the program and computer cannot perform its work without memory device because the memory affects the performance of it directly. It is used to access the memory and all memory depends on RAM device. Your desktop performs smoothly on operating the various functions at a particular time owing to this greater access of the RAM. All data is stored in the hard disk device and a hard disk has the space available of around 160 GB that is extendable Hard disks. Here are external hard disks available as well and that is to have a great space to store data about all the information. That is why it reduces the risk about of losing the data consist of information.
The device Memory is to run the program in the computer and computer do not perform its work without the memory device and that is directly affects the performance of it that is also use to access to the memory. The memory device depends on the random access memory device. It is advisable to have greater access to the RAM for the desktop without problems in the functioning of a range of functions at a given time. Likewise, the hard drive is the device that stores all data in it. Usually, a hard disk has available space of 160 GB. Hard drives are renewable. A user can expand the hard drive to suit your preferences. In addition, there are external hard drives available. It is considered to have a large space to store all information and data. Therefore reduces the risk of losing data. The keyboard and the mouse also important components of it and these are designed to the compatible of the screen. Now keyboards, mouse and screens are also available which has wireless access data. The monitor is also its vital
place for accessing data that is a source of displays the images and data. Now today monitors has two forms. In two forms one is the flat screen and another one is the cathode ray tube. Each completes and device has a vital role and has its own individual purpose for it.
