Hard to say.
- The Colossus (1944) built to break German High Command teletype cyphers processed 8 bits of the code stream at a time. But only 5 of the 8 were encrypted character data.
- Many 1950s business computers operated on characters instead of words, but these were usually 6 bit characters not 8 bit characters.
- The IBM 7030 Stretch (1961) defined a byte a a variable length of 1 to 8 bits.
- The IBM System 360 (1964) defined a byte as 8 bits. The 360 was also the first computer to address memory at the byte/character level, regardless of the size or type of data being accessed. The 360/20 and 360/30 implementations used microcoded 8 bit processors to interpret the System 360 instruction set, but other versions of the 360 used processors with larger word size (both microcoded and hardwired logic implementations).
- During the minicomputer era CPUs were frequently either 12 bit (e.g. DEC PDP-8) or 16 bit (e.g. DEC PDP-11, Data General Nova) but there may have been some 8 bit CPUs in this period.
- Intel's 8008 (1972) was the first 8 bit microprocessor CPU.

Who invented ink?
The Chinese invented the black mose at first and then when the Egyptians found out, they took the idea and change it a little bit and called it ink.
What is the difference between 7-bit ASCII and 8-bit ASCII?
ASCII is a 7 bit code developed and standardized by the telegraph industry for use on teletypes as a replacement for their older Baudot 5 bit code. The computing industry when they adopted ASCII extended it in several different nonstandard ways to an 8 bit code because after 1964 (when the IBM System 360 was introduced) the standard computer memory unit had become the 8 bit byte.
Who invented the glass eye?
glass master jenkins invented the glass eye
Original ASCII codes were 7 bit or 8 bit?
ASCII is a 7 bit code. There are many nonstandard extensions of ASCII to 8 or 9 bits by various computer companies. ASCII was developed to replace the obsolete 6 bit BAUDOT teletype code and was never originally intended for use on computers.
What part of china was the umbrella invented in?
Yes, the Chinese invented the Umbrella during the Wei Dynasty in the late B.C. era.
Was atari 2600 4 bit?
No, there were no 4-bit consoles. The 2600 uses the 8-bit 6507 CPU and an 8-bit bus.
Can a 16-bit CPU process 2 bytes at a time?
14
How many data buses does a CPU have?
it has 8 data buses and 16 adress buses....that is why it an 8 bit microprocessor
How many bits are contained in the A register of a 8085 CPU?
8085 is a 8 bit microprocessor and so A register which is also known as accumulator is also 8 bit.
What made the 8088 Intel CPU special compared to its predecessors?
The 8088 was a 16 bit microprocessor implemented on an 8 bit databus.
How does the CPU identify between 8 bit and 16 opertion?
Each assembly/machine instruction has a unique value which indicates what operation is to be performed, what addressing mode, etc. Typically one of these codes or bit(s) within the code would indicate if this were a 16 bit code. In this way, if the CPU received an 8 bit code with no extension for 16 bit mode, it would run the 8 bit code (assuming that when 8 bits instructions were written it didn't have to be future/forward compatible).
When was 4 bit 8 bit 16 bit 32 bit and 64 bit micro processors invented?
The year of 1972.
Which is the fastest a 64 bit CPU 32 bit CPU 16 bit CPU?
64bit, It can use more than 3gb of ram, while 32bit can utilise only 3gb.
Where was the CPU invented?
china
What is the difference between 32 bit and 64 bit CPU?
The difference between a 32 bit and 64 bit CPU is the speed in which a computer will read and process the information. A 64 bit CPU will read much quicker and can handle the memory usage better than a 32 bit.
When the first CPU invented?
1971.
Who invented the CPU of computer?
a taco
