Printed circuit board of a DVD player. Part of a 1984 Sinclair ZX Spectrum computer board, a printed circuit board, showing the conductive traces, the through-hole paths to the other surface, and some electronic components mounted using through-hole mounting. A printed circuit board (PCB), also called printed wiring board (PWB), is a medium ...
A motherboard (also called mainboard, main circuit board, MB, base board, system board, or, in Apple computers, logic board) is the main printed circuit board (PCB) in general-purpose computers and other expandable systems. It holds and allows communication between many of the crucial electronic components of a system, such as the central ...
Process control block. A process control block (PCB), also sometimes called a process descriptor, is a data structure used by a computer operating system to store all the information about a process. When a process is created (initialized or installed), the operating system creates a corresponding process control block, which specifies and ...
CSE. Computer science and engineering (CSE) or Computer Science (CS) also integrated as Electrical engineering and Computer Science (EECS) in some universities, is an academic program at many universities which comprises approaches of computer science and computer engineering. There is no clear division in computing between science and ...
A circuit built on a printed circuit board (PCB). An electronic circuit is composed of individual electronic components, such as resistors, transistors, capacitors, inductors and diodes, connected by conductive wires or traces through which electric current can flow. It is a type of electrical circuit. For a circuit to be referred to as ...
Circuit design. The process of circuit design can cover systems ranging from complex electronic systems down to the individual transistors within an integrated circuit. One person can often do the design process without needing a planned or structured design process for simple circuits.
Science and technology. Polychlorinated biphenyl, an organic chlorine compound, now recognized as an environmental toxin and classified as a persistent organic pollutant. Printed circuit board, a board used in electronics. Plenum chamber burning, in some jet engines. Papillary carcinomas of the breast, rare forms of the breast cancers.
Chip on board (COB) is a method of circuit board manufacturing in which the integrated circuits (e.g. microprocessors) are attached (wired, bonded directly) to a printed circuit board, and covered by a blob of epoxy. [1] Chip on board eliminates the packaging of individual semiconductor devices, which allows a completed product to be less ...
