working of microprocessor
Answers
A microprocessor -- also known as a CPU or central processing unit -- is a complete computation engine that is fabricated on a single chip. The first microprocessor was the Intel 4004, introduced in 1971. The 4004 was not very powerful -- all it could do was add and subtract, and it could only do that 4 bits at a time. But it was amazing that everything was on one chip. Prior to the 4004, engineers built computers either from collections of chips or from discrete components (transistorswired one at a time). The 4004 powered one of the first portable electronic calculators.
MICROPROCESSOR
A microprocessor is a digital electronic device in which millions of transistors are designed using integrated circuits as integrated circuits or ICs. This also serves as the CPU or CPU, the central processing unit of the computer. The invention of integrated circuits was the way forward for the creation of a microprocessor.
Before microprocessors came into existence, CPUs were built by connecting individual electronic components or by circuits with small-scale integration. The first microprocessor was built in the 1960s. It was then used to compute binary coded decimal BCD in electronic calculators. Later, 6 and 7 bit microprocessors were used in terminals, printers and automation devices.
There are mainly two large microprocessor manufacturing companies in the world - Intel INTEL and AMD. Among these, processors of Intel company are used more. Each company gives different code names according to the technology and capacity of the processors, such as Intel's main processors are Pantium 1, Pantium 2, Pantium 3, Pantium 4, Celeron, Core to Duo etc. Amd The major processors of the company are K-5, K-6, Athelon etc.
