One kHz (KiloHertz) is equal to 1,000 Hertz, which is a measurement of frequency.

Ku-Band refers to the bandwidth of electromagnetic wave between 12 GHz to 14 GHz, which is primarily used in satellites operating at 14 GHz uplink and 11 GHz downlink in supporting braodband TV and Direct Broadcast Satellite (DBS) system (DSS).

Keyboard is the input device that enables user to enter data into a computer, control cursor and pointer locations, and to control the dialog with the computer.

A killer micro is a microprocessor-based machine that infringes on mini, mainframe, or supercomputer performance turf. Often heard in "No one will survive the attack of the killer micros!", the battle cry of the downsizers. Used especially of RISC architectures.

Keyboard, Video, Mouse (KVM) switch is a hardware device that enables a single keyboard, video monitor and mouse to control multiple computer. Although multiple computers are connected to the KVM, only one can be controlled at a time. Modern devices have also added the ability to share USB devices and speakers with multiple computers. KVM switches are popular among users who have upgraded their home PC systems and want to still use their old computers but do not want to invest in a second keyboard, monitor and mouse. KVM switches are also used by business to save money when one person uses more than one computer and in server farms where it is only necessary to periodically access each separate server in the farm one at a time.

Kazaa Lite K++ is a later versions of Kazaa Lite included K++, which added a memory patcher that removed search limit restrictions, multi-source limits, and set one's "participation level" to the maximum of 1000. KaZaA Lite K++ has the ability to resume downloads, play files, block your IP address from the RIAA. Kazaa Lite K++ is obsolete and replaced by Kazaa Lite Resurrection (or simply Kaza Lite).

Kazaa Lite Resurrection, also known as Kazaa Lite, is a P2P file sharing client that supports the FastTrack P2P network. Kazaa Lite Resurrection is to continue the development forward on the now obsolete Kazaa Lite K++ application. Kazaa Lite Resurrection technology utilizes the core of Kazaa Media Desktop (KMD) and runs on Windows. Kazaa Lite Resurrection does not contain any adware or spyware. It also offers numerous improvements over KMD such as no bit-rate limits, expanded support for multi-source downloads, and additional P2P tools.

Kazaa Lite Revolution is an alternative, unauthorized FastTrack P2P network client. Kazaa Lite Revolution, instead of Kazaa Media Desktop, may be used to connect to FastTrack. Revolution is sometimes advertised as an improved version of KMD. Their appearance is similar, but Revolution removes all advertising and adds several new features and tools. Kazaa Lite Revolution is a different application from Kazaa Lite Resurrection.

Kazaa, also spelled as Kazzaa, is a free, peer-to-peer file sharing service over the Internet. To use Kazaa, a person downloads and installs a software client of Kazaa. Kazaa clients communicate with various registration servers, using Internet protocols, to identify files for sharing or download. The Kazaa P2P network holds peer registration information and then brokers connections between any two peer clients for file sharing.

Kazaa Lite, also known as K-Lite, is a peer-to-peer file-sharing computer program. Kazaa Lite is an unauthorized modification of the Kazaa Media Desktop application which excludes adware and spyware and provides slightly extended functionality. It became available in April, 2002. It can be downloaded free of charge, and, as of mid-2005, is almost as widely used as the official Kazaa client itself. It connects to the same FastTrack network and thus allows to exchange files with all Kazaa users
