Correct Answer :   Wired Equivalent Privacy

WEP stands for Wired Equivalent Privacy. It is a security algorithm for IEEE 802.11 wireless networks. Introduced as part of the original 802.11 standards ratified in 1997, its intention was to provide data confidentiality comparable to that of a traditional wired network. It was superseded by Wi-Fi Protected Access (WPA) in 2003.

Correct Answer :   Protocol

In information technology, a protocol is an agreement between the communicating parties on how communication is to proceed. Violating the protocol makes communication more difficult, if not impossible. A protocol is the specialist set of rules that end points in a telecommunication connection.

Correct Answer :   Integrated circuit

IC stands for Integrated Circuit. It is a set of electronic circuits on one small plate (“chip”) of semiconductor material, normally silicon. Also known as chip or microchip, ICs are the heart and brains of most circuits and are are a keystone of modern electronics.

Correct Answer :   Cache

The memory buffer used to accommodate a speed differential is called cache. It is a hardware or software component that stores data so future requests for that data can be served faster. Cache serves to add fast memory between the CPU and main memory.

Correct Answer :   Content-addressable Memory

Content-addressable memory (CAM) is a special type of computer memory used in certain very-highspeed searching applications. It is also known as associative memory. It compares input search data (tag) against a table of stored data, and returns the address of matching data (or in the case of associative memory, the matching data).

Correct Answer :   Ctrl + Alt + Delete

The three-finger salute refers to the original PCcompatible system command to reboot or restart a computer by pressing three keys simultaneously: Control, Alt and Delete. The three-key combination of Control-Alt-Delete is specifically designed to be impossible to execute with one hand in order to avoid the potential for accidental reboots. It was developed by David Bradley.

Correct Answer :   To receive and redirect communication signals

A communications satellite works like a relay station: signals transmitted by the ground stations are picked up by the satellite’s receiver antennas, the signals are filtered, their frequency changed and amplified, and then routed via the transmit antennas back down to Earth. The redirected signals are received by ground stations, also called earth stations and further processed to extract the base band signals.

Correct Answer :   Watson

Watson is an IBM supercomputer that combines artificial intelligence (AI) and sophisticated analytical software for optimal performance as a "question answering" machine. The supercomputer is named for IBM's founder, Thomas J. Watson.

Correct Answer :   7

The modern Internet is not based on OSI, but on the simpler TCP/IP model. However, the OSI 7-layer model is still widely used, as it helps visualize and communicate how networks operate, and helps isolate and troubleshoot networking problems.

Correct Answer :   Linux

A new breed of embedded technology is emerging using customized versions of the Android operating system. At first blush, Android may sound like an odd choice as an embedded OS, but in fact Android is already an embedded OS, its roots stemming from Embedded Linux.
