| Karaoke | The singing of popular songs to prerecorded music.

| Kbps | Kilobits per second (thousands of bits per second). A unit of measurement for modems that indicates the speed at which data is transferred. One kilobit is equal to 1,024 bits, but is commonly rounded to 1,000 bits. |
| Keyboard | An input device used to type programs, instructions and data into the computer. Similar to the keys on a typewriter. |
| Keyboard Shortcut | A keystroke or combination of
keystrokes that is used as a substitute for a longer series of keystrokes or
mouse clicks. Using keyboard shortcuts allows you to keep your fingers on the
keyboard instead of having to reach for the mouse. They can save time and frustration.
An example is using CTRL+S to save a document in Microsoft Word. You simply
press these two keys together to save the document without having to reach for
the mouse and click on an icon or menu item. CTRL+S works in many other
programs as well.

| Keylogger |
This is a form of spyware. Once a
keylogger is installed on a computer it can record every keystroke that is made
on that computer and transmit it back to the person who created the keylogger. The
purpose of a keylogger is to steal passwords, bank account numbers, and other
personal information.

| Kilo-Mega-Gigabyte | A computer does all its computing with on/off switches, therefore it works in the binary number system, which has just two unique digits, 0 and 1. The off position is represented by 0; the 1 represents on. All computer memory and storage systems are also calculated in binary. There are three commonly used measurements, a kilobyte, a megabyte, and a gigabyte.
Kilobyte (K or Kb) – in decimal systems, kilo stands for 1,000 but in binary systems a kilo is 1,024 (2 to the 10th power). It is, however, often used to loosely represent 1,000. The original IBM PC came which 64 K, which means that the main memory could store or process 65,536 bytes, or characters of information at any one time.
Megabyte (M or Mb or Meg) – a megabyte is 2 to the 20th power or 1,048,576 bytes. If your current computer has 256 Mb of memory, that means that the main memory can store or process approximately 268,435,456 bytes or characters of information at any one time. Quite an improvement over the original IBM PC!
Gigabyte (G or Gb) – a gigabyte is 2 to the 30th power or 1,073,741,824 bytes. A gigabyte is equal to 1,024 megabytes.

| Kilobyte | Technically, a kilobyte is 1024 bytes. This is, however, often rounded to a thousand bytes. |
| Kiosks |
A small structure with a computer
screen that you stand in front of and interact with. Kiosks are often used in airports to print out boarding passes
and assign seats. They have also become popular for printing pictures.
