Installation of Computer Hardware and Software

Advancement in computer technologies make changes in the software and hardware of the computer. A computer has two parts one is software that constitutes the programs that run in it and the other one is hardware that constitutes the hardware part of computer like monitor, keyboard and all the peripheral devices that are connected to it.

Here below installation of both hardware and software in computer is describes in a very simple way:

Computer Software Installation:

The functioning scheme of your computer is an significant factor to be advised when you establish any software.

External Hardware

The external hardware includes all the peripherals that are connected to the desktop computer externally, through different ports. These are USB, serial and parallel port, firewire, bluetooth, PS/2 and PC card. The external hardware installation can be done by a normal user, even without much knowledge of computers. Be careful when you connect hardware to computer that is hardware is connected to the computer after switching it off.

Internal Hardware

Connection of internal hardware is not easy as external hardware.It is complicated and requires some basic knowledge about the computer internals. The CPU cabinet is opened by removing the side panels of the cabinet. Identify the slot in which you have to plug your hardware. Plug in the hardware that is to be installed and ensure that it has fit properly into its slot. The side panel and the screws are replaced into their original places and all the wires are connected to their respective slots. The power cord can then be plugged into the mains and the computer can be switched on.

Computer Firewall

Computer Firewall a very important tool which a common user have but don’t know how to use it. Computer is indispensable need of human. Computer firewall is an important security tools provided to protect computer form external threats likes virus, malware, spyware etc. As we have internet as major information provider you can find absolutely correct data with instances.

The computer firewall performs the following functions:
