Ethernet - Ethernet (this name comes from the physical concept of ether) is a frame-based computer networking technology for local area networks (LANs). It defines wiring and signaling for the physical layer, an. Used . d frame formats and protocols for the media access control (MAC)/data link layer of the OSI model. Ethernet is mostly standardized as IEEEs 802.3. It has become the most widespread LAN techno. Used . logy in use during the 1990s to the present, and has largely replaced all other LAN standards such as token ring, FDDI, and ARCNET. ...

Analog signal - An analog or analogue signal is any variable signal continuous in both time and amplitude. It differs from a digital signal in that small fluctuations in the signal are meaningful. Analog is usually t. Used . hought of in an electrical context, however mechanical, pneumatic, hydraulic, and other systems may also use analog signals.

The word "analog" implies an analogy between cause an. Used . d effect, voltage in and voltage out, current in and current out, sound in and frequency out.

An analog signal uses some property of the medium to convey the signal's information. For example, an ...

Amplifier - The amplifier can be considered to be any device that uses a small amount of energy to control a larger amount, although the term today usually refers to an electronic amplifier. The relationship of t.
