K:

See Kilo

KA:

See Keep Alive

KA BAND:

Term used to identify communications frequencies in the 20-30GHz range.

kbps:

Kilobits per second, 1,000 bits per sec; equal to 10 to the third power.

KBS:

Kilobytes per second, 1,000 bytes/sec

KEEP ALIVE (KA):

Identifies a message used in the Link Management Interface (LMI) frame relay port to verify link integrity.

KERMIT:

A term used for Columbia University's flexible, asynchronous file transfer protocol used for Personal Computer (PC) communications.

KEY:

   In reference to a database, a Key would be an identifier for a single collection of data, such as a record, a row, or an object. In history it could be the Key part of Key and Sounder, Morse code.

KEYBOARD DIALING DATA ADAPTER:

The facility that initiates data and voice calls from Data Terminal Equipment (DTE) through a data adapter.

KEYBOARD LANGUAGE:

The language used when typing on the keyboard. Some programs that are designed for the Windows platform recognize this setting. When a user adds a new keyboard language, a keyboard layout for that language is also added.

KEYBOARD LAYOUT:

A keyboard arrangement that accommodates the special characters and symbols used in different languages: Keyboard layouts affect which characters appear when a key is pressed on the keyboard. If a user changes the keyboard layout the characters that appear on the screen may no longer correspond to the characters that are printed on the keyboard keys.

KEYING:

A method of encoding the data carrier through signal modulation: In terms of past maintenance activity this could refer to the keying of a signal for test purposes.

KEYING (MODEM):

Another term for the process of modulating a carrier signal in order to encode binary information

KG:

See Key Generator

Khz:

Kilohertz, one thousand Hertz (frequency)

KILO (K):

A prefix (term): Designates one thousand times a specific unit

KSR:

Keyboard Send / Receive: On-line terminal capable of transmitting and receiving. See ASR.

KU BAND:

Microwave radio frequencies in the region of 10 to 20 gigahertz, portions of which are used for satellite operations at 12 to 14 gigahertz and local terrestrial ‘bypass’ at 10 and 18 gigahertz.
