The most fundamental part of an operating system. The kernel stays resident in memory at all times, often hidden from the user, and manages system memory, the file system, and disk operations.
The processor mode that allows full, unprotected access to the system. A driver or thread running in kernel mode has access to system memory and hardware.
Driver for a logical, virtual, or physical devices.
The typewriter-like set of keys used to input data and control commands to the computer. Most keyboards use a QWERTY layout, and may also have a calculator-like numerica keypad off to one side, as well as a set of cursor-movement keys.
A small amount of system memory used to store the most recently typed keys, also known as the type-ahead buffer. Some utility programs let you collect a number of keystrokes or commands and edit or reissue them.
Most computers use a keyboard based on the traditional QWERTY typewriter-like keyboard.
In the IBM PC and DOS computers, the most common keyboard currently used has 101 keys, with 12 function keys arranged over the top of all the other keys.
A plastic card that fits over certain keys (usually the function keys) on the keyboard to remind you how to use them. These templates are specific to an application, and can be very useful if you are an occasional user, or you are learning to use the program.
A prefix indicating 1000 in the metric system. Because computing is based on powers of 2, in this context kilo usually means 2(to the tenth), or 1024. To differentiate between these two uses, a lowercase k is used to indicate 1000 (as in kHz), and an uppercase K to indicate 1024(as in KB).
Abbreviated Kb or Kbit. 1024 bits(binary digits).
kilobits per second
Kbps. The number of bits,or binary digits, transmitted every second, measured in multiples of 1024 bits per second. Used as an indicator of communications transmission rate.
