In electrical and safety engineering, hazardous locations (HazLoc, pronounced haz·lōk) are places where fire or explosion hazards may exist. Sources of such hazards include gases, vapors, dust, fibers, and flyings, which are combustible or flammable. Electrical equipment installed in such locations can provide an ignition source, due to ...
The Model 33 keyboard generates the seven-bit ASCII code, also known as CCITT International Telegraphic Alphabet No. 5, with one (even) parity bit and two stop bits, with a symbol rate of 110 baud, but it only supports an upper-case subset of that code; it does not support lower-case letters or the `, {, |, }, and ~ characters.
v. t. e. In computing, input/output ( I/O, i/o, or informally io or IO) is the communication between an information processing system, such as a computer, and the outside world, such as another computer system, peripherals, or a human operator. Inputs are the signals or data received by the system and outputs are the signals or data sent from it.
The Windows Code Page 1252 was an extension of ISO/IEC 8859-1 (8859 Part 1 or "ISO Latin-1") standard, so it had the degree sign at the same code point, 0xB0. The code point in the older DOS Code Page 437 was 0xF8 (248 decimal); therefore, the Alt code used to enter the symbol directly from the keyboard is Alt+ 248. Lookalikes
Both Eagle Computer and Columbia were sued by IBM for copyright infringement of its BIOS. They settled and were forced to halt production. Neither the Columbia nor the Eagle were nearly as IBM PC DOS compatible as Compaq's offerings. Commodore SX-64. The first full-color portable computer was the Commodore SX-64 in January 1984.. Atari STacy
A computer keyboard is a peripheral input device modeled after the typewriter keyboard which uses an arrangement of buttons or keys to act as mechanical levers or electronic switches. Replacing early punched cards and paper tape technology, interaction via teleprinter -style keyboards have been the main input method for computers since the ...
Power-on self-test. A power-on self-test ( POST) is a process performed by firmware or software routines immediately after a computer or other digital electronic device is powered on. [1] POST processes may set the initial state of the device from firmware and detect if any hardware components are non-functional.
A quiet, silent or fanless PC is a personal computer that makes very little or no noise. Common uses for quiet PCs include video editing, sound mixing and home theater PCs , but noise reduction techniques can also be used to greatly reduce the noise from servers.
