1. SNMP (Simple Network Protocol)

It allows network administration to connect to and manage network device.

2. SCSI (The Small Computer System Interface)

The Small Computer System Interface (SCSI) is a set of parallel interface standards developed by the American National Standards Institute (ANSI) for attaching printers, disk drives, scanners and other peripherals to computers.

3. Swapping

Storing    programs     on    disk,    and    then transferring  these programs  into main storage  as and when they  are  needed.  The  technique   is used  to process   large programs,  or several  programs  with limited  memory.

4. Synchronous Transmission

In synchronous   transmission,   a group  of characters   is blocked  in same  way  as records  are blocked  on magnetic tape. A header and trailer  are then added  to each block to convert  it into a frame . The header contains  synchronization   information   used by the receiving  device  to set its clock  in synchronism  with sender end clock.  It also  contains   information   to  identify  the  sender  and  receiver.   The  header   is followed   by  a block  of characters  containing  actual  message  to be transmitted.

5. Spiders or Web Robots

Upto 7 devices excluding the OC can be attached through a single SCSI connection, linking them together(Known as daisy chain)  Only 1 device at a time can transmit through thee SCSI connection – the devices are prioritized.

9. SDRA (Synchronous Dynamic Random Access Memory)

It is a type of RAM capable of speeds of about 55 Mhz. It has superseded EDO RAM.

10. SLIP (Serial Line Internet Protocol)

It is basically a standard which enables a user to connect to the internet using a modem and a telephone line.

11. SOHO (Small Office Home Office)

It describes those business that are either run from home or in a small office. OK you may well have you gone to the trouble of including this definition in a glossary of PC and Internet terminology. The reason is that software and hardware companies will promote  their products as being suitable for the SOHO market. Please do not confuse this with the SOHO market in London.

12. SQL (Structured Query Language)

It is a standard for managing, retrieving, changing and deleting records from relational data bases.

13. SVGA (Super visual graphics array Video Adaptor)

A SVGA monitor   up to 1280X1024 pixels using over 16million different colours.


1. Transducer

A  device   capable   of  changing   signals  from analog  to digital  form,  or vice-versa.

2. Transponder

A  device   mounted   on  a  communication satellite   that  receives,   amplifies,   and  retransmits   signals from earth stations.

3. Tele-medicine

It is phone based and internet based advice to a patient. The phone or a computer near a patient can also record the pulse rate, ECG, temperature, and blood pressure.

4. T-I

It is a leased line internet connection. The speed at which data can be transmitted is 1.45 megabits per second.

5. T-3

It is a leased line internet connection. The speed at which data can be transmitted is 45 megabits per second.

6. TWAIN (Technology without interesting name)

A standard interface used with devices such scanner.
