Mell Why computer is called programmable?
A computer is a programmable machine that receives input, stores and manipulates data, and provides output in a useful format. Many electronic devices are computers that perform only one operation, but they are still following instructions that reside permanently in the unit.
What does it mean to say a computer is programmable?
a. A device that computes, especially a programmable electronic machine that performs high-speed mathematical or logical operations or that assembles, stores, correlates, or otherwise processes information. b. Such a device along with peripherals, especially a monitor, keyboard, and mouse. 2.
Why does a computer need program?
Programming languages use classes and functions that control commands. The reason that programming is so important is that it directs a computer to complete these commands over and over again, so people do not have to do the task repeatedly. Instead, the software can do it automatically and accurately.
Why was the first programmable computer important?
Colossus, the first electronic digital programmable computing device, was used to break German ciphers during World War II. It is seen here in use at Bletchley Park in 1943.
What is the first programmable computer?
ENIAC
ENIAC, in full Electronic Numerical Integrator and Computer, the first programmable general-purpose electronic digital computer, built during World War II by the United States.
What makes a computer a ” programmable ” computer?
programmable computer. Also found in: Dictionary, Thesaurus, Medical, Financial. A redundant term, because what makes a computer a computer is that it follows a set of instructions. Many electronic devices are computers that perform only one operation, but they are still following instructions that reside permanently in the unit.
What is the function of a programmable logic device?
A programmable logic device ( PLD) is an electronic component used to build reconfigurable digital circuits. Unlike integrated circuits (IC) which consist of logic gates and have a fixed function, a PLD has an undefined function at the time of manufacture.
What was the first fully programmable digital computer?
Colossus was the first combining digital, (partially) programmable, and electronic. The first fully programmable digital electronic computer was the ENIAC which was completed in 1946.
What are the functions of a programmable controller?
The most basic function of a programmable controller is to emulate the functions of electro-mechanical relays. Discrete inputs are given a unique address, and a PLC instruction can test if the input state is on or off.
