4004 is the first general purpose microprocessor by Intel
4004
6 general purpose registers.i.e., B,C,D,E,H,L
Microprocessor consists of different types of registers. They special purpose registers, general purpose registers, address registers, floating point registers and constant registers.
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
to initialise the chip in microprocessor....that is for which purpose we are going to use it......

Most modern cell phones contain two different computers and a microwave transmitter/receiver. The first computer uses a standard general purpose microprocessor for general data handling and call management purposes, the second computer uses a special purpose microprocessor called a digital signal processor (DSP) for handling voice processing and often photo compression/decompression processing. Of course there is also a battery, display, and touch sensor array.
