"microprogramme”—

A sequence of elementary instructions, maintained in a special storage, the execution of which is initiated by the introduction of its reference instruction into an instruction register.

"most immediate storage"

The portion of the "main storage" most directly accessible by the central processing unit:

(a) For single level "main storage", this is the internal storage; or

(b) For hierarchial "main storage”, this is:

(1) The cache storage;

(2) The instruction stack; or

(3) The data stack.

"multi-data-stream processing"-

The "microprogramme" or equipment architecture technique which permits processing two or more data sequences under the control of one or more instruction sequences by means such as

(a) Parallel processing; or

(b) Structured arrays of processing elements.

"net capacity"

Of a drum, disk or cartridge-type streamer tape drive, or a bubble memory:

The total capacity designed to be accessible to the "digital computer" excluding error control bits.

"non-volatile storage"/

A storage device the contents of which are not lost when power is removed.

"other peripheral device"--

A "data device" which is:

(a) Peripheral to a central processing unit--"main storage" combination; and

(b) Not an input/output control unit-drum, disk or magnetic tape drive or bubble memory combination.

"principal element"-

A "digital computer" or "related equipment” which is:

(a) Either "embedded" or "incorporated" in another equipment or system; and

(b) In replacement value more than 35 per cent of the replacement value of the total equipment system, i.e. including the "digital computer" or "related equipment".

"programme"

A sequence of instructions to carry out a process in, or convertible into, a form executable by an electronic computer.

"real time processing"-

Processing of data by an electronic computer in response to an external event according to time requirements imposed by the external event.

"related equipment"-

Equipment "embedded" in, "incorporated" in, or "associated" with electronic computers, as follows:

(a) Equipment for interconnecting "analogue computers" with "digital computers”;

(b) Equipment for interconnecting "digital computers";

(c) Equipment for interfacing electronic computers to "local area networks" or to "wide area networks";

(d) Communication control units;
