S
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
They are programs normally run by these sites which browse your site and add what it finds to tis database of subjects and pages. Spiders can create a heavy load on a www site and virtually overload it by progressively through every document, requesting these documents at a very rapid rate.

7. Syntax Errors
Occur when rules or syntax of a programming language are not followed. Such program errors typically involve incorrect punctuation, incorrect word sequence, undefined terms or misuse of terms.
8. SCSI
Small computer systems interface introduced by the American National Standards Institute (ANSI). A SCSI connects PC’s to Peripherals and to other PC’s and LANs. 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 It has superseded EDO RAM.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.
T
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.
