(1)becoz the memory space in the chip will be low so we need an extenal memory for storing a data
(2)the accessing 8 bit is faster in microprocessor due to parallel processing
For a 3/8 bolt, you should use a 3/8 drill bit.
You use a 0.875 bit or a 7/8 bit . They are the same size.
For a 3/8 bolt, you should use a 5/16 drill bit.
As technology has moved on from 8 - bit the only use for it now is hobby
With a bit of a cheat: 88 + 8/8 = 89
It can process 8 bit data simultaneously ... In pcs we use 64 k bit which means it can process 64 bits of data at a time :)
I would use a 5/8 drill bit which is almost exactly 16mm.
8 bit registers cannot be used as 16 bit registers. The reverse works, however, as the 16 bit general purpose registers of the 8086 and 8088 can be used as pairs of 8 bit registers. AX is divided into AH (high 8 bits) and AL (low 8 bits), and BX, CX, and DX are similarly divided.Operations on 16 bit and operations on 8 bit registers are similar. So you can do add ah, bl, just as you could do add ax, bx.
An 8 bit microprocessor is a 'microprocessor' which only has an 8 bit wide databus.
Because IBM wanted to build a computer with an 8-bit data bus. The 8086 and 8088 are the same processor, with the 8086 running on a 16-bit data bus, and the 8088 running on an 8-bit data bus. This allowed IBM to make the most use of older designs that supported 8-bit data buses, such as the 8080, the 8085, and the Z80.
For drilling into metal, use a Phillips head drill bit that is 1/8 inch in size.
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.
