Because it is expensive and give profits to business.
An 8 bit microprocessor is a 'microprocessor' which only has an 8 bit wide databus.
Because it is an 8-bit microprocessor.
The Intel 8080 was the first microprocessor using an 8 bit databus.
8 bit input is given to Intel 8085 microprocessor.
MC6800
It is depended on how many bits the processor can process simultaneous... Means 8 bit microprocessor can process 8 bit of data simultaneously... & also it has 8 line data bus.. to transfer the data between memory & IO devices.... In same way for 64 bit..
8085 is a 8 bit microprocessor designed by Intel Co.
The 8085 is an 8-bit microprocessor. Even though there are some 16-bit registers (BC, DE, HL, SP, PC), with some 16-bit operations that can be performed on them, and a 16-bit address bus, the accumulator (A), the arithmetic logic unit (ALU), and the data bus are 8-bits in size, making the 8085 an 8-bit computer.
Register size and address buss siez.
Even though the 8085 is an 8 bit microprocessor, it can address 64K memory, because it has a 16 bit address bus.
b/c the 8085 microprocessor is the first 8 bit microprocessor which Intel is produces in 1877 and this is the first general purpose 8 bit microprocessor. there was an 8 bit general purpose register before 8085 named as 8008 but this microprocessor is not functional 8 bit microprocessor
