What does the word 8 bit processor mean?
In computer architecture, 8-bit integers, memory addresses, or other data units are those that are at most 8 bits (1 octet) wide. Also, 8-bit CPU and ALU architectures are those that are based on registers, address buses, or data buses of that size. Eight-bit CPUs normally use an 8-bit data bus and a 16-bit address bus which means that their address space is limited to 64 KBs. This is not a "natural law", however, so there are exceptions. The first widely adopted 8-bit microprocessor was the Intel 8080, being used in many smart cards and hobbyist computers of the late 1970s and early 1980s, often running the CP/M operating system. The Zilog Z80 (compatible with the 8080) and the Motorola 6800 were also used in similar computers. The Z80 and the MOS Technology 6502 8-bit CPUs were widely used in home computers and game consoles of the 70s and 80s. Many 8-bit CPUs or microcontrollers are the basis of today's ubiquitous embedded systems. There are 28 (256) possible values for 8 bits.(in binary) About 55% of all CPUs sold in the world are 8-bit microcontrollers or microprocessors http://en.wikipedia.org/wiki/8-bit

64bit processors have most registers specially the integer registers as 64bit. It can handle 64bit wide internal and external data. All internal and external buses may or may …not be 64bit wide.. - Neeraj Sharma
It means the processor is able to handle a 32bit wide data at a time.
Intel 8008 was world's first 8 bit microprocessor.
The internal parts like registers and ALU use data in 8-bits in a 8 nit processor and so in a 16 bit and 32 bit processor the use 32 bit data.....the BUS which carries data fr…om one part of a proceesor to another has 8-lines in a 8 bit processor,16 lines in a 16 bit and 32lines ina 32 bit one.....because all these bits have to be transmitted simultaneously.
No, it is a 32-bit processor in the sense of using 32-bit virtual addresses and having 32-bit general purpose registers and ALU that operates on those 32-bit GPRs. It does fea…ture "MMX Technology", which can process 64-bits of information at a time by reusing the FPU's registers, however, in the more common usage, it is not considered a 64-bit processor due to the lack of 64-bit virtual address space and 64-bit GPRs.
8bit 16 bits 32 bits and 64 bits and 128 bits imply a broadside [parallel] output of that many bits of digital information on a buss output. these bits represent a word output…. therefore the longest the word the more information can be processed at a time imply more bits the faster the computer or data flow.
The year of 1972.
The 8085 is called an 8-bit processor because the integers andmemory addresses it could handle were 8 bits in width. The 8086could handle 16-bit integers and memory addresses.…
An 8 bit microprocessor is a 'microprocessor' which only has an 8 bit wide databus.
As technology has moved on from 8 - bit the only use for it now is hobby
Embedded processors still use 8 and 16 bit, especially if it's legacy hardware being supported. General purpose desktops have been 32 or 64 bit for awhile.
8 bit ALU and most of data processing registers will be 8 bit
In Computer Hardware
Most kinds of data is organised into 8-bit blocks, so a processor of any bit width (4, 8, 16, 32, 64, etc) will need to be able to handle 8-bit (byte-wise) data.
In Computer Terminology
An 8 bit processor can transmit one letter at a time. In the ASCII code, each of the first 127 combinations of bits has a special standard meaning. The last 127 is given a spe…cial meaning. So an an 8 bit processor can transmit 256 bits at a time. An A is 65 bits. A 16 bit processor can transmit two letters at a time. A B is 66 bits. An E is 69 bits. It can transmit a B and an E. By definition that is considered a word. A difference exists between the way computer people use the language and normal people use it. Actually, a piece of equipment called a bus attached to the processor does the actual transmitting.
In Software Engineering
When you say that a computer has a 16 bit processor, you mean that the fundamental data size of the accumulator and registers is 16 bits. Examples of 16 bit processors include… the DEC PDP-11, the Intel 8086/8088, and the MODCOMP Classic, circa 1980.
In Intel 8085
Because the bus size is 8 bit.. There are multiple answers to this.. One may say that the processor is capable of processing 8 bits of data at a time so its an 8 bit pro…cessor.
