Question: LK can you let me know of the ports in rear of computer casing.

By MAx from Sentul

Well, There you go, these are the standard mainboard ports tat mostly you can see back at your pc casing.

SERIAL PORT

(where you insert in the serail version mouse )

USB Port

Universal Serial Bus: a protocol for transferring data to and from digital devices. Many digital cameras and memory card readers connect to the USB port on a computer. A single USB port can be used to connect up to 127 peripheral devices, such as mice, modems, and keyboards. USB also widely supports Plug-and-Play installation (reducing the need to install special software for connectable devices) and hot plugging (removing and adding of devices without the need to switch off or restart your machine).
These days, you're likely to find USB ports on the front of your machine, as well as the back, as USB devices are universally popular and are in frequent use. Older USB ports will typically be USB 1.1, supporting data rates of up to 12Mbps. Just about every USB device and computer sold these days will work at the high-speed specification of USB 2.0, capable of transferring data at a rapid 480Mbps.

RJ-45 Ethernet port

A local-area network (LAN) architecture developed by Xerox Corporation in cooperation with DEC and Intel in 1976. Ethernet uses a bus or star topology and supports data transfer rates of at least 10 Mbps, with higher rates on Fast Ethernet and Gigabit Ethernet standards. Ethernet is the most widely implemented LAN standard.
A modern version of Ethernet, called Fast Ethernet (or 100Base-T), supports data transfer rates of 100 Mbps, typically compatible with standard Ethernet connections.
The best new major version is Gigabit Ethernet, supporting data rates of 1 gigabit (1,000 megabits) per second.

PS/2 Ports

The PS/2 Ports are simple, 6-pin, low-speed connections commonly dedicated to a keyboard and mouse. Although these ports may look identical at first glance, they are not interchangeable, so you'll need to attach the keyboard and mouse to their respective PS/2 port. Luckily, all modern computers have colour-coded connectors, with keyboards designated as light purple, with a computer mouse using green.If you elect to use a USB keyboard and mouse, you can typically disable the PS/2 ports in the system's CMOS setup and free the PS/2 system resources for other devices.

Modem RJ-11 Jack

The presence of this usually indicates that you have an internal modem, giving you up to 56kps internet access through dial-up. RJ-11 is short for Registered Jack-11, a four- or six-wire connector used primarily to connect dial-up modems and other telephone equipment. RJ-11 connectors are also used to connect some types of local-area networks (LANs), although RJ-45 (Ethernet) connectors are more common.

VGA Monitor Port

Video Graphics Array: used to connect a CRT monitor to the computer.


Mini Audio JACK

With just about every sound card, you get three 3.5mm sockets. The green socket is known as the 'line-out' socket, and is the most commonly used, as it outputs audio from the PC. Ready for headphone or speaker usage. The blue socket is 'line-in' and as the name suggests, does the opposite of line-out, by acting as an audio input, so you can play audio and have it recorded in certain PC sound programs, using this connection. The pink socket is also an audio input device, and is designated for analogue microphones.

DB 25 parellel Port

The parallel port is not usually supported on modern PCs. Typically used for printers, the modern range of printing equipment has preferred to use USB connectivity for single PCs, with network capabilities via Ethernet and wireless for a growing number of network-enabled printers. You'll find some printers do include parallel connections for older computers.

Well, there is more ports but these are the mostly used and available in personal computers and laptops.

Thanks for you mail Max,

keep mailing.
