Import and Export (Strategic Commodities) Regulations

[1988 Ed.

[Subsidiary]

"firmware".

See "microprogramme".

"gross capacity"-

The product of:

(a) The maximum number of binary digit (bit) positions per unformatted track;

and

(b) The total number of tracks including spare tracks and tracks not accessible to the user.

"hybrid computer"--

Equipment which can:

(a) Accept data;

(b) Process data, in both analogue and digital representations; and

(c) Provide output data.

"image digitizer"--

A device for directly converting an analogue representation of an image into a digital representation.

"image enhancement"

The processing of externally derived information-bearing images by algorithms such as time compression, filtering/extraction, selection, correlation, convolution or transformations between domains (e.g. Fast Fourier Transform or Walsh Transform). This does not include algorithms using only linear or rotational transformation of a single image, such as translation, feature extraction, registration or false colouration.

"incorporated" in equipment or systems-

(a) Can feasibly be either:

(i) Removed from such equipment or systems; or

(ii) Used for other purposes; and

(b) Is essential to the operation of such equipment or systems.

"local area network”-

A data communication system which:

(a) Allows an arbitrary number of independent "data devices" to communicate directly with each other; and

(b) Is confined to a geographical area of moderate size (e.g. office building, plant, campus, warehouse).

"main storage"--

The primary storage for data or instructions for rapid access by a central processing unit. It consists of the internal storage of a "digital computer" and any hierarchical extension thereto, such as cache storage or non-sequentially accessed extended storage.

"maximum bit packing density”.

The density of recording specified in accordance with the appropriate ANSI or ISO Standard (e.g. ANSI X3.14-1979, ISO 1862–1975; ANSI X3.22–1973; ISO 1873-1976; ANSI X3.39–1973; ISO 3788–1976; ANSI X3.48–1977; ISO 3407–1976, ANSI X3.56–1977/ISO 4057-1979; ANSI X3.54–1976).

"maximum bit transfer rate"-

(a) of a drum or disk drive (Ridmax) is the product of:

(1) The maximum number of binary digit (bit) positions per unformatted track; and

(2) The number of tracks which simultaneously can be read or written, divided by the rotational period;

(b) of a magnetic tape drive (Rumax), is the product of:

(1) The "maximum bit packing density";

(2) The number of data bits per character (ANSI) or per row (ISO); and

(3) The maximum tape read/write speed.
