(Bayonet Nut Coupling) A commonly used plug and socket for audio, video and networking applications that provides a tight connection. Using a mount somewhat similar to the way a bayonet (knife) is mounted onto the end of a rifle, BNCs are used to connect a variety of different coaxial cable types.

The BNC (Bayonet Neill–Concelman) connector is a miniature quick connect/disconnect radio frequency connector used for coaxial cable. It features two bayonet lugs on the female connector; mating is fully achieved with a quarter turn of the coupling nut.

Cache memory is an intermediate form of storage between the ultra-fast registers and the RAM. The CPU uses cache memory to store instructions and data that are repeatedly required to execute programs, thereby improving the overall system speed and increasing the performance of the computer. Maintaining frequently accessed data and instructions in the cache helps in avoiding the need to access the slower DRAM repeatedly. CACHE memory is widely used for memory caching. Cache memory is basically a portion of memory made of high speed static RAM (SRAM) instead of the slower and cheaper DRAM which is used for main memory.

ADSL (Asymmetric Digital Subscriber Loop) ADSL connects millions of home Subscribers to the internet at megabits/sec Rates over the same telephone local loop that is used for plain old telephone service. In Sec. 2.5.3, we described how a device called a DSL modem is added on the home side. It sends bits over the local loop to a device called a DSLAM (DSL Access Multiplexer), pronounced "dee-slam," in the telephone company's local office.
