1D

One dimensional, having a single dimension (such as length).

1GL

First generation computer language, namely machine code. cf 2GL.

10Base-2

The 10Base-2 standard (also called Thinnet) uses 50 ohm coaxial cable (RG-58 A/U) with maximum lengths of 185 meters. This cable is thinner and more flexible than that used for the 10Base-5 standard. The RG-58 A/U cable is both less expensive and easier to place. Cables in the 10Base-2 system connect with BNC connectors. The Network Interface Card (NIC) at each computer requires a T-connector allowing two cables to be attached to adjacent computers. Any unused connection must have a 50 ohm terminator. The 10Base-2 system operates at 10Mbps and uses baseband transmission methods. The terminator at one end should be grounded.

10Base-5

Thick coaxial Ethernet cable (Ethernet over Thick-net coax).

10Base-T

Unshielded twisted pair network cable.

10GbE

10 Gigabit Ethernet. 10 Gigabit Ethernet was ratified on 12th June 2002 as a supplement to the 802.3 standard the defines Ethernet.

21CN

21st Century Network. A British Telecom project for migrating telephony services from PSTN to an end to end IP based network.21CN is designed to support voice, video and data services.

24/7

24 hours a day, 7 days a week.

2D

Two dimensional. Having two dimensions.

2D6

Two six sided dice. The abbreviation 2D6 is used in some games to indicate the use of two standard six sided dice.

2GL

Second generation computer language, namely assembler. Assembler allows mnemonic programming, which represents each machine code instruction with an easier to remember mnemonic.

2K3

Abbreviation for 2003. Normally used to indicate a version of a Microsoft product. So depending on the context 2K3 may mean Windows 2003 (server) or Exchange 2003.

2L8

Chat abbreviation meaning "Too Late".

3D

Three dimensional. Having three dimensions.

Normally taken as height, width and depth, but the actual names and meanings of the three dimensions may depend on the application or context.

3D6

Three six sided dice. The abbreviation 3D6 is used in some games to indicate the use of three standard six sided dice.

3DES

Triple DES. Enhancement to DES encryption where the data is encrypted through three parses through the DES algorithm. It uses a 168bit key.

3G

Third generation mobile phone/network.

3GL

Third generation computer language. Also known as "high-level" languages. It includes C, C++, Java, Basic, Fortran, Pascal and others. A third generation language compiles a program written in the language into machine code.

4D

Four dimensional. Having four dimensions.

Four dimensional is often taken as height, width, depth and time, but the actual names and meanings of the four dimensions depend on the application or context.

4GL

Fourth generation computer language. A software language intended to be much closer to natural language than 3GLs.

5GL

Fifth generation computer language. Generally considered to be any visual programming environment where drag-and-drop techniques can be used to build up a GUI application. Normally based on a 3GL or 4GL language. 5GL therefore includes Delphi, Visual Basic etc.

//

1. Part of an address specification. Such as in "http://www.cryer.co.uk". Most web browsers take "//" to mean "http://", assuming the http protocol where none is explicitly specified.

2. To be continued. Possibly German in origin or use.
