Hello Readers uptill now we are very much clear with the computer basics ,in the last section we have seen Computer memories and its types and various uses ,Now what left is the Computer Input OutPut Ports, lets discuss about the Various computer input out put ports and cables over here.
Just to Give you basic overview Port are available at the rear or front of your Computer Box,its main function is to plugin pheripheral device through Cable into Computer Box,So it is the point of interface.
There are Various Ports Available ,you must be aware of some of theme as we frequently use them in our life.
First of All lets Talk about the Seriol Port and Parallel Port, then we will discuss the rest of the ports available
- Using serial port data is transmitted one bit at a time through a single wire.
- The data transmission speed is quite slow.
- it is commonly known as communication (COM) ports or RS232C ports
- devices like mouse and modem are use these Ports
- It Can Send 8 Bits at a time Simulteneously
- Data Transmission is Faster than serial Ports
- printers, scanners, CD writers connected using these Ports
1 PS/2 Ports:
- 6-pin, low-speed serial connections commonly used to connect a keyboard and mouse
2 VGa Monitor Port
- Video Graphics Array is used to connect the monitor to the computer.
4 ethernet Port
- There is a built in Ethernet port on most computers to connect it to a wired network. Ethernet ports are also
found on all popular broadband routers.
5. S-Video Port
Short for Super-Video, a technology for transmitting video signals over a cable by dividing the video information into
two separate signals
6 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. USB card readers are typically faster than cameras or readers
that connect to the serial port, but slower than those that connect via FireWire which is an external bus standard that
supports data transfer rates of 12 Mbps. A single USB port can be used to connect up to 127 peripheral devices, such
as mouse, modems, and keyboards. USB also supports Plug-and-Play installation and hot plugging.
7 firewire Ieee 1394 Port
FireWire is a cabling technology for transferring data to and from digital devices at high speeds. Some professional digital cameras and memory card readers connect to the computer over FireWire. FireWire card readers are typically faster than those that connect via USB. Also known as IEEE 1394, FireWire was invented by Apple
Computer, but is now commonly used with Windows-based PCs as well.
8 Mini audio Jack
Audio connectors are used to affix cables to other audio equipment, providing electronic signal transference and
grounding protection,Used to connect Audio Device Like Speakers etc
In this type of port, data is transmitted through Infrared waves. For infrared transmission the device and the computer both must have infrared ports. These allow computers and peripherals to communicate serially over an Infrared link rather than over cables. The remote control of our TV sets uses the same technology. For wireless
data communication between computers and various peripheral devices we use infrared ports.
Bluetooth is used to connect mobile phones, computers and PDAs using a short range wireless connection. This technology uses radio waves to transmit data between any two devices. The devices that are Bluetooth enabled contain a small transceiver chip that allows them to communicate with other Bluetooth enabled computer or device.
Data can be exchanged at the rate of about 2 megabit per second.
