Different Kinds Of Computer Systems

The brilliance of the computer can not be praised an excessive amount of, since it is true. Recently, the device is apparently getting smaller and much more portable, which may have seemed to be an impossibility taking into consideration the size of the very first computers. Computers now can be found in different sizes and are thus get categorized into quite a number of categories with respect to the criteria used to group them.

With regard to how the commands in the computer are executed, we get three types of computers, and they are, the analog, digital and hybrid computers. The analog computers used mechanical energy to execute commands and are not in use today. The digital computer was an improvement as it is able to perform more than one task at a time. The hybrid computer is a combination of the two types of computers and works by converting the signals that are analog to digital.

The mainframe computers refer to the computers that are used for operations that are quite bulky (as the computer is quite bulky in nature, and occupies quite some space). They are mostly in use in the offices of large corporations, and are used instead of numerous small servers. The microcomputers refer those computers that are much smaller than the mainframes. These usually use a microprocessor to carry out its operations. The regular desktop computers could be regarded as microcomputers, and thus this means that the microcomputers are best for use for single individuals.

There are lots of computers that are best for use by single individuals and it would be best to look at what is there for then in the market. The desktop computers are those that are for use in a particular place as they are not portable. Most of them are found in offices or homes. The laptop could be said to be a portable version of the desktop as it is able to perform all the duties that could be accomplished on the desktop, only that they operate on rechargeable batteries. The Personal Digital Assistant (PDA) refers to a handheld computer that consists of a touch screen. It could perform such duties as playing music, storing data, access the internet. The tablet computer is much larger than the PDA, but is not preferred due to their nature of being limited on the use of software. The supercomputers are those that are particularly designed to perform highly specialized tasks such as quantum physics calculations.
