Memory cell (binary)

The memory cell is the fundamental building block of computer memory . The memory cell is an electronic circuit that stores one bit of binary information and it must be set to store a logic 1 (high voltage level) and reset to store a logic 0 (low voltage level). Its value is maintained / stored until it is changed by the set / reset process. The value in the memory can be accessed by reading it.

Flip-flop (electronics)

In electronics , a flip-flop or latch is a circuit that has two stable states and can be used to store state information. A flip-flop is a bistable multivibrator . The circuit can be made to change state by signals applied to one or more inputs and will have one or two outputs. It is the basic storage element in sequential logic . Flip-flops and latches are fundamental building blocks of digital electronics systems used in computers, communications, and many other types of systems.

Digital timing diagram

digital timing diagram is a representation of a set of signals in the time domain. A timing diagram can contain many rows, usually one of them being the clock. It is a tool that is ubiquitous in digital electronics, hardware debugging, and digital communications. Besides providing an overall description of the timing relationships, the digital timing diagram can help find and diagnose digital logic hazards .

Digital electronics

Digital electronics and digital (electronic) circuits are electronics that handle digital signals (discrete bands of analog levels). All levels within a band of values ​​represent the same information state . In most cases, the two voltage bands are one and the same voltage. These correspond to the false and true values ​​of the Boolean domain . Because of this discretization , relatively small changes to the analog signal levels of the discrete envelope, Continue Reading “Digital electronics”

Digital cross connect system

digital cross-connect system (DCS or DXC) is a piece of circuit-switched network equipment, used in telecommunications networks, that allows lower-level TDM bit streams , such as DS0 bit streams, to be rearranged and interconnected among higher-level TDM signals, such as DS1 bit streams. DCS units are available as both T-carrier and E-carrier bit streams, as well as newer SONET / SDH bit streams.
