It depends on the particular simulator. You need to be more specific in your question.

What is the difference between intel 8085 and zilog Z80?
1.8085 has multiplexed data lines where as Z80 does'nt has multiplexed lines. 2.8085 operates at 3-5MHz clock freq,But clock frequency of Z80 is 4-20MHz. 3.8085 contains 74 instructions and Z80 has 158 instructions. 4.8085 has 5 interrupts but Z80 has only 2. 5.8085 has no index register but Z80 has 2. 6.8085 contains SIM & RIM instructions, but Z80 does'nt .

Can a PC accept more memory than its address line permits?
For current hardware, the answer would be "typically no". Modern computers have so many address lines that there is little chance that more memory could be needed than was possible to add within the constraints of the address bus. With microcontrollers and older computers, though, this is not the case. By means of a technology called "bank switching", it is possible to have more memory available than the address lines can support. In the days of the Z80, a chip with 16 address lines and 65,536 maximum bytes of memory, computers were available with three 48K memory banks in addition to the native 64K bank, for a total of 212,992 bytes of addressable memory. A standard called LIMM EMS was available in the days of the IBM PC/AT that would allow the same sort of additional memory. The way these systems work is by defining a window in the standard address space, and then allowing the processor to select the extended memory that it wants to see in that window. Selecting the memory is typically "out of band", meaning that the processor writes a page number to an I/O port, for instance, and then that page of memory becomes visible in the defined window.
List some information about the Z80 processor and the transistors it contained?
Z80 contained 8.500 transistors. See the site I linked below for more information.

What is advantage of rotate with carry in z80?
The Z80's rotate-with-carry instructions, RRC and RLC, for Rotate Right and Rotate Left, are great for taking action based on individual bits being set or cleared. If you start with a clear carry flag, then get a byte from wherever, then you can rotate left or right one bit at a time. The bit you want to examine will eventually be in the carry. Then, execute a JP C, (location) or JP NC, (location) to jump based on whether or not the bit is set. (Of course, you could also use JR). The beauty of RLC and RRC is that they don't destroy the byte that you are using - after doing enough rotates, the byte will be as it was before.
What component of the computer keeps track of the address in memory of the programming instruction being executed?
A stored-program computer at least needs to know which instruction it has to execute next. Other memory addresses of special significance are e.g. the top of one or more stacks, or addresses to be used by instructions.To keep track of such addresses, all CPUs have one or more registers; for instance the address of the next instruction is stored in the instruction pointer, a.k.a. program counter. Which and how many registers of a CPU are designated to keep addresses depends on the CPU type. The Z80 for instance has a program counter, a stack pointer, two index registers and an indirect address register doubling as 16 bit accumulator, while the contemporay 6502 only has a program counter and a stack pointer.
When did Microsoft and apple become compitable?
Apple and Microsoft have a long history of compatibility. They merged their names for AppleSoft Basic in 1977. In 1980 produced a RAM card that added 16KB of memory to the Apple II computer and a Microsoft SoftCard which added a Z80 processor so it could run the CP/M operating system.
Why is the Op-code the first part of an instruction loaded into the instruction register of the CPU?
Not necessarily. Some processors (Z80, for example) allow "prefixes" before the op-code.
Program in TI Basic for the 15 MHz Z80 instead of for the 6 MHz Z80?
The TI-83 Plus has a clock speed of 6MHz. The newer TI-83 Plus Silver Edition and the entire TI-84 Plus series have a 15MHz clock speed, but usually run at 6MHz for compatibility with the older 83+. Assembly programmers can switch between the two speeds with a simple command. Unfortunately, BASIC programmers can not. They can use an assembly program that will do it for them, though.
What do you mean by an 8-bit microprocessor?
8 bit architecture means that the processor computes 8 bits at a time. these 8 hold instructional characterists for the processor to operate. higher bits ( we like to say wider) allow for a larger library of instructions are much more memory references.
