1GL
|
First generation programming language.
Also known as machine code. Essentially this is programming in binary.
Fortunately this is no longer a skill required in the IT industry. Ultra old
school.
|
1st Line Support
|
When the user reports a problem, this
is the point where the IT department first attempts to resolve the problem.
Some help desks endeavour to provide first line support. Some are simply call
loggers.
|
24x7
|
A term used to mean all-day and
everyday. Usually used in the context of service availability.
|
2GL
|
Second generation programming
language. Also known as assembler. Considered as very low level and old
school. Assembler programmers can be found in the world of real-time
development.
|
2nd Line Support
|
If 1st line support
cannot solve a user’s problem, it is handed to 2nd line
support. These people usually work
within the IT department.
|
2½G
|
Not quite 3G. A term used to describe
wireless cellular technology that offers Web access, but without offering the
full functionality of 3G. Eg. GPRS. Used with email reading devices such as
the Blackberry.
|
3G
|
Wireless broadband. Third generation
mobile telephony providing full multimedia to the palm top device. It is a regulated technology and so
service providers need to acquire 3G licences.
|
3GL
|
Third Generation programming
Language. A type of programming language that is characterised by the use of
English words like IF, THEN, ELSE and GOTO.
Very powerful but poor on the user interface and database access side
of things. Created in an era before the arrival of PCs with good-looking GUI
interfaces.
|
3rd Line Support
|
If the problem cannot be solved by
2nd line support it will go to 3rd line support. If 3rd line cannot solve the
problem, it cannot be solved.
|
4G
|
Broadly speaking it is 3G only
faster. However it embraces IP networking and places great emphasis on
quality of service, security and cost.
|
4GL
|
Fourth Generation programming
Language. Similar to 3GLs but have better capability regarding GUI
development and database access. e.g.
Visual Basic, Visual C++.
|
5GL
|
Fifth Generation programming Language. These languages promised a
future underpinned by artificial intelligence and robotics. Their window of
opportunity has now closed so they are only of historical interest today.
Examples of 5GLs include Prolog and Lisp.
