64 bit. the size of accumulator will always equal to the size of processor. e.g 32 bit processor has 32 bit accumulator.

Actually on some computers the accumulator(s) are larger than the processor word size. Some examples are:
Some computers do not have accumulator(s), these fall into three main groups:
Comparison between micro processor Intel and Motorola
The Selective Service Act, although the definition you give of it is a bit misleading.
A fair bit
I was just reading that the size of the deck where the Pilgrims lived was 68 feet by 22 feet, but there was a small boat stored there (30 by 6) so the living space was quite a bit smaller.

The main advantage of a 64 bit operating system is that it can make use of all the features and performance of a modern 64 bit microprocessor. If you run a 32 bit operating system on a modern 64 bit microprocessor the operating system will not be able to make use of any 64 bit features of the microprocessor and the performance will not be what the microprocessor is capable of.However a 64 bit operating system WILL NOT run at all on a 32 bit microprocessor (or one with a smaller word size) as the microprocessor does not implement the 64 bit features needed for the operating system to work.Note: in the not too distant future microprocessor manufacturers will release 128 bit microprocessors, which will require 128 bit operating systems to use all the features and performance of these microprocessors.
The size of the accumulator is the same,means 64bit.
Generally, the bit size of a processor is indicated by the size of the accumulator, which is, most times but not always, the same as the internal data bus size. The 8086/8088 processor, for instance, is a 16 bit processor. The 8085 is an 8 bit processor. The 80386 is a 32 bit processor. The Q6600 Core2 Quad is a 64 bit processor. (These are just examples.)
Accumulator is a general purpose register.it is a 8 bit register in 8085. it stores the temporary results of a current operation doing by 8085.it is also called 'A' register
The 8086/8088 processor is called a 16 bit processor because its basic architecture is 16 bits wide. Its registers and accumulator are 16 bits wide, and the primary data it manipulates without extra work is 16 bits wide.
the accumulator is an 8-bit register then is part of the arithmetic/logic unit(ALU). this register is used to store to store 8-bit data and to perform arithmetic & logical operation. the result of an operation is stored in the accumulator. the accumulator is also identified as register A.
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.
8085 is a 8 bit microprocessor and so A register which is also known as accumulator is also 8 bit.
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.
The memory unit's size that depends on the processor is the bit.
bit size is a wordlength of one memory location
It is an 8 bit register which is accessable to programmer and is main fuction is to perfom all arithmetic and logical function.
A means accumulator , it is used to store 8 bit data not address because address is of 16 bits .
