A 4 bit microprocessor is a device that integrates the function of the Central Processing Unit (CPU) of a computer unto one semiconductor chip or integrated circuit.
The first Intel 4-bit micrprocessor, and arguably the first ever microprocessor was the the 4004, introduced in 1971.
1971!it was 4004!
Because it is an 8-bit microprocessor.
An 8 bit microprocessor is a 'microprocessor' which only has an 8 bit wide databus.
8 bit input is given to Intel 8085 microprocessor.
The disadvantage of the bit slice microprocessor is that it is slow that it why it was slow with earlier processors.
The question is unclear, but it looks like it meant to ask when the first microprocessor was invented. That was the Intel 4004, invented in 1971. It was the first single chip microprocessor, and the first microprocessor available commercially. The 4004 was a 4 bit processor, with a 12 bit address bus and an 8 bit opcode. Everything was multiplexed, 4 bits at a time, in 8 clock cycles per instruction.
it is a 16 bit microprocessor & it has 40 pin .
The main advantage of a 64 bit operating system is that it can make use of all the features and performance of a modern 64 bit microprocessor. If you run a 32 bit operating system on a modern 64 bit microprocessor the operating system will not be able to make use of any 64 bit features of the microprocessor and the performance will not be what the microprocessor is capable of.However a 64 bit operating system WILL NOT run at all on a 32 bit microprocessor (or one with a smaller word size) as the microprocessor does not implement the 64 bit features needed for the operating system to work.Note: in the not too distant future microprocessor manufacturers will release 128 bit microprocessors, which will require 128 bit operating systems to use all the features and performance of these microprocessors.
The Intel 8080 was the first microprocessor using an 8 bit databus.
8085 is a 8 bit microprocessor designed by Intel Co.
The Intersil 6100 family consisted of a 12-bit microprocessor and a range of peripheral support and memory ICs.
