keyboard (pointing mouse, trackball, joystick), scanning (fax machine, image scanner), and
voice-recognition devices. Output is by screen (CRT, flat-panel display), printer
(dot-matrix, laser, ink-jet), and sound, processing and memory hardware consists of the
CPU (the processor) and memory. Secondary storage stores data on floppy-disk, hard-disk,
optical-disk, and magnetic tape devices. Communication devices include modems) for
enabling computers to talk over phone lines), cable, and fax modems. Hardware consists
of all machinery and equipment. In a computer system, the hardware includes, among other
devices, the keyboard, the screen, the printer, the computer or processing devices, the
mouse, and more. When you connect your computer devices, such as a printer and the screen
to you computer, you connect a cable from the devices to the port (a connector) that
appears on the back of you computer. Depending on the device, the type of cable you use to
connect the device to you PC will differ.
Your Computer's Port
A port is a connector that let you connect a device to your PC. These devices include
your monitor, a mouse, printer, keyboard, and other accessories. In the back of you PC,
you will find several different ports through which a cable run to connect the divices to
your computer.
The male and female ports.
The ports are designed as either male or female ports. Some ports are designed to plug
into a cable, while other are designed for a cable to be plugged into the port. Ports and
cables are classified as male or female, based on whether they plug in or are plugged
into. A male cable or connector contains visible pins that plug in. On the other hand, a
female cable or connector does not have such pins. If your computer has a female port, you
need a male cable to connect and if it has a male port, you need a female cable. There is
a gender changer that is also available in the market. It is used to change the cable from
female to male or from a male to female to fit you computer need. The other difference in
a port is the number of pins it has. |
