The OUT instruction on the 8085 uses 10 T cycles, 3 for opcode fetch, 1 for opcode decode, 3 for port address fetch, and 3 for port data store. Any wait states encountered are above and beyond that.

Why the name 8085 Why the name 8085 for microprocessor?
8085 is a microprocessor designed by Intel
When 8085 processor was invented?
The 8085 was introduced by Intel in 1977.
Why 8085 microprocesseor cannot have more than 256 instruction?
Intel designed the 8085 as a 8 bit computer, with the opcode byte as the first byte of the instruction. As such, there are only 256 possible values for the first opcode byte. (28 = 256) As implemented, Intel provided only 83 different instructions.It is possible, however, in general, that secondary opcode space be usable, so the "8 bit" rule might not necessarily apply, but Intel chose to not implement any of them on the 8085, like they did on the 8086/8088.
What the Difference between accumulator and register?
The accumulator is a general register that holds a value. It is also a special register that can be used as the target for the result of various arithmetic or logical computations. For instance, if you wanted to add two numbers, you could load the first into the accumulator, add the second to the accumulator, and then store the accumulator where wanted. The instruction register is an internal register that holds the value of the instruction opcode in order for the 8085 to decode and process the instruction. While it is shown on the Intel block diagram for the 8085, it is not directly accessible by the running program - it is for internal use only by the 8085.
What is the instruction for exit in 8085 microprocessors?
There is no exit instruction in the 8085. Do you mean return, as in from a function or interrupt? If so, the instruction is RET.
What the Difference between accumulator and instruction register?
Examples: /360: no accumulator 8080: A 6800: A and B 8086: AX ...
What is the data size in Intel 8085?
The data size in the 8085 is 8 bits.
Is there a multiply instruction?
Not in the 8085.
