Why 16-bit processor is used to process 8-bit data?

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.


How does 8086 determine wheather instruction is 8 bit or 16 bit?

based on the size of the data bus they determine whether it is a 8 bit or 16 bit . here in 8086 it has 16 bit data bus hence it is called as 16 bit microprocessor


What is the bit rate for the signal in which 8 bit lasts 16 ns?

Bit rate = 8 / (16 * 10-9) bits/second


Is 8-bit ISA forwards-compatible with 16-bit ISA?

Most 8-bit ISA cards should work in a 16-bit slot (unless they are hardwired to an incompatible IRQ or have a skirt on them). Some 16-bit ISA cards can operate in an 8-bit slot, but most will not.


How can you say whether the controller is 8-bit controller or a 16 bit controller?

the uc is 8 bit or 16 is depended on ALU and speed of process and seeing the ports


How do you use 8 bit register as 16 bit register?

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.


How many bits in 8085 microprocessor?

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.


Isa is a which bit technology?

8/16


Why 8085 cannot be 16-bit microprocessor?

Because it is an 8-bit microprocessor.


Which expansion slot type started as an 8 bit architecture and expanded to 16 bits?

The ISA slot started as 8-bit, and then evolved to 16-bits.


How do you add and subtract an unlike fraction?

first you need to find the common bottom bit e.g 9/8 +6/16. first you need to do 8 times _ equals 16 and the answer is 2 so now whatever you do to the bottom you have to do to the top so the question is now 18/16 + 6/16 witch is 24/16


What is the width of a bus?

a. 8 bit b. 16 bit c.32 bit d.64 bit
