Computer Peripherals To Accelerate The Performance Of Your Pc.

Computer peripheral is a term that is sometimes referred exclusively for devices that are connected externally, generally those that are connected through some form of computer bus like the USB. Its most common examples include joysticks, printers and scanners.

However in a mixed opinion, some people say, internal devices like the video capture cards are not really computer peripherals since they are added inside the computer case. In their opinion the term peripherals is exclusively reserved for devices that are hooked up externally to the computer. It is arguable however whether PCMCIA cards qualify as peripherals under this biased definition. Because there are some hard wares that go fully inside the laptop, while some others like WiFi cards, have external appendages.



Due to these deliberations, the term is hardly used these days. Earlier these were used to refer to things like floppy disk drives and modems. Now a day抯 most of these devices are integrated inside the computer's case. Over and above the external devices typically function on their own such as mp3 players and cell phones.
