An interactive keyboard layout for Macintosh that shows for each typeface the characters available in uppercase, lowercase, and with option keys. The user picks a font from a pull-down menu, and the characters of that font show on the keyboard. Pressing the shift key will show the uppercase layout, and pressing the option key or option-shift will show additional characters. The equivalent utility for Windows is Character Map.
key cap
The top part of a keyboard key.
kilobaud
One thousand baud.
kerning
Reducing the spacing between certain pairs of letters in a proportional-pitch type to improve the appearance of the line of type. Proportional-pitch fonts often have automatic kerning of certain letter pairs; in a good type program, the operator can adjust the automatic kerning for style preference, or can kern individual pairs as needed. For example, A and V look better next to each other if they are moved closer together than, for example, A and B.
kilobyte
(k, KB, Kb; also Kbyte or K-byte). One thousand bytes (103) or 1024 (210) bytes. A unit of measurement used for computer file sizes.
kilobit
(Kb, Kbit, K-bit, kbit). One thousand bits (103) or 1024 bits (210). A unit of measurement of the capacity of memory integrated circuits. Not to be confused with kilobyte.

Explanation : Kernel, in computer technologies, is the central part in most computer operating systems for the management of the system's resources and the communication between hardware and software components. As a basic component of an operating system, a kernel provides abstraction layers for hardware, especially for memory, processors and I/O that allows hardware and software to communicate. It also provides software facilities to userland software such as process abstractions, inter-process communication and system calls. Kernel may also mean an essential subset of a programming language or core language, in terms of which other constructs are (or could be) defined.
