A flat-panel display (FPD) computer monitor A cathode-ray tube (CRT) computer monitor A computer monitor is an output device that displays information in pictorial or textual form. A discrete monitor comprises a visual display , support electronics, power supply, housing , electrical connectors , and external user controls.
The AND gate is a basic digital logic gate that implements the logical conjunction (∧) from mathematical logic – AND gates behave according to their truth table. A HIGH output (1) results only if all the inputs to the AND gate are HIGH (1). If all of the inputs to the AND gate are not HIGH, a LOW (0) is outputted.
The term can also be used as part of an action; to "perform I/O" is to perform an input or output operation. I/O devices are the pieces of hardware used by a human (or other system) to communicate with a computer. For instance, a keyboard or computer mouse is an input device for a computer, while monitors and printers are output devices.
A monochrome display is a type of CRT common in the early days of computing, from the 1960s through the 1980s, before color monitors became popular. [4] They are still widely used in applications such as computerized cash register systems. Green screen was the common name for a monochrome monitor using a green "P1" phosphor screen.
The interface is primarily used to connect a video source to a display device such as a computer monitor, though it can also be used to transmit audio, USB, and other forms of data. Unline HDMI, DisplayPort is open source. drive bay A standard-sized area within a computer case for adding hardware (hard drives, CD drives, etc.) to a computer.
Jack appears identical to more common three-contact stereo audio-only 3.5 mm TRS connector. DisplayPort: DisplayPort (DP) was designed to replace VGA, DVI, and FPD-Link and standardized by VESA. [2] It is primarily used to connect a video source to a display device such as a computer monitor.
Each logic gate is designed to perform a function of Boolean logic when acting on logic signals. A logic gate is generally created from one or more electrically controlled switches, usually transistors but thermionic valves have seen historic use. The output of a logic gate can, in turn, control or feed into more logic gates.
In digital electronics, a NAND gate (NOT-AND) is a logic gate which produces an output which is false only if all its inputs are true; thus its output is complement to that of an AND gate. A LOW (0) output results only if all the inputs to the gate are HIGH (1); if any input is LOW (0), a HIGH (1) output results.
