A 4-bit synchronous counter using JK flip-flops. In a synchronous counter, the clock inputs of the flip-flops are connected, and the common clock simultaneously triggers all flip-flops. Consequently, all of the flip-flops change state at the same time (in parallel). For example, the circuit shown to the right is an ascending (up-counting) four ...
In data transmission, parallel communication is a method of conveying multiple binary digits ( bits) simultaneously using multiple conductors. This contrasts with serial communication, which conveys only a single bit at a time; this distinction is one way of characterizing a communications link . The basic difference between a parallel and a ...
High-Level Data Link Control (HDLC) is a communication protocol used for transmitting data between devices in telecommunication and networking. Developed by the International Organization for Standardization (ISO), it is defined in the standard ISO/IEC 13239:2002. HDLC ensures reliable data transfer, allowing one device to understand data sent ...
Asynchronous circuit ( clockless or self-timed circuit) [1] : Lecture 12 [note 1] [2] : 157–186 is a sequential digital logic circuit that does not use a global clock circuit or signal generator to synchronize its components. [1] [3] : 3–5 Instead, the components are driven by a handshaking circuit which indicates a completion of a set of ...
PC100 is a standard for internal removable computer random-access memory, defined by the JEDEC. PC100 refers to Synchronous DRAM operating at a clock frequency of 100 MHz, on a 64-bit-wide bus, at a voltage of 3.3 V. PC100 is available in 168-pin DIMM and 144-pin SO-DIMM form factors. PC100 is backward compatible with PC66 and was superseded by ...
Asynchronous system. The primary focus of this article is asynchronous control in digital electronic systems. [1] [2] In a synchronous system, operations ( instructions, calculations, logic, etc.) are coordinated by one, or more, centralized clock signals. An asynchronous system, in contrast, has no global clock.
Synchronous conferencing or synchronous computer-mediated communication (SCMC) is any form of computer-mediated communication that occurs in real-time; that is, there is no significant delay between sending and receiving messages. [1] SCMC includes real-time forms of text, audio, and video communication. SCMC has been highly studied in the ...
Asynchronous serial communication is a form of serial communication in which the communicating endpoints' interfaces are not continuously synchronized by a common clock signal. Instead of a common synchronization signal, the data stream contains synchronization information in form of start and stop signals, before and after each unit of ...
