- first-generation computer
The first type of computers. They used valves, mercury delay lines, electrostatic memories and had very limited storage. - flag
This is an indicator that has two states, often called set or unset. It enables the program to record whether a particular event has occurred, for example whether (or not) a list of numbers has been sorted, whether an interrupt has been detected (or not detected). In a high-level language a variable may be used as a flag. If a Boolean or logical data type is used, the two states, true and false, are equivalent to the flag states set and unset. To begin with the flag may be unset (false) and when a particular case is detected it is set (true); when the action has been completed it is unset again (back to false). - flame

Software created by Macromedia - flat file database
A database held as a table and stored in a single file. The data will be structured with a row for each record and a column for each field. This allows only very simple structuring of the data, which can only be considered as a two-dimensional table (hence - flat screen

The type of, for example, a variable which is used to store float numbers. - floating-point numbers
Numbers which are expressed as a binary or decimal fractional value, together with an integer exponent. - floppy disk
A removable magnetic disk which is used to store data and is often used to transfer files from one computer to another or as a backup device for small files. Once available in 5.25 and 8 inch formats, the floppy disk is now only commercially used in its hard cased 3.5 inch version. It has a small capacity of only 1.44 Mb. - flowchart

When a function or procedure is used, the calling program must pass parameters to it. The formal parameter links the data in the calling program to its use in the function or procedure. - formal specification
