How do pointer work in c program?
Pointer can be defined as variable that is used to store memory address , usually the location another variable in memory. Pointers provide a means through which memory location of a variable can be directly accessed.
What are the Functions of the memory buffer register?
In other words, MAR holds the memory location of data that needs to be accessed. When reading from memory, data addressed by MAR is fed into the MDR (memory data register) and then used by the CPU. When writing to memory, the CPU writes data from MDR to the memory location whose address is stored in MAR. The Memory Address Register is half of a minimal interface between a microprogram and computer storage. The other half is a memory data register. Far more complex memory interfaces exist, but this is the least that can work.
What is the difference between main and auxiliary memory?
The major difference between main memory and auxiliary memory is that main memory is directly accessed by CPU but the auxiliary memory is not accessed by the CPU directly.For this the data is first transferred to main memory from auxiliary memory and then from main memory the data is transferred to the CPU for further processing.

What is auxiliary memory give an example of auxiliary memory?
The major difference between main memory and auxiliary memory is that main memory is directly accessed by CPU but the auxiliary memory is not accessed by the CPU directly.For this the data is first transferred to main memory from auxiliary memory and then from main memory the data is transferred to the CPU for further processing. Some examples of auxiliary memory would be disks, external hard drives, USB drives, etc.
Does rom a primary storage?
Yes. ROM (Read Only Memory) is a primary memory. BIOS is a Read Only Memory and is directly accessed by the cpu just like RAM (Random Access Memory). So it is a primary storage.
What does ram memory do?
the function of a memory ram is to store memory that can be accessed later on.
Maximum memory address space that the processor can access directly if it is connected to a 16-bit memory?
Max. memory address space= 216 X 2 bytes = 128 Kbytes

Can a pendrive act as a RAM?
A pendrive cannot act as ram. RAM's memory is volatile and directly connected to the motherboard. A pendrive can only act as physical memory.
How can the memory other than four 64KB segments be accessed by 8086?
You can access any location in memory. You need only to load its segment address and then refer to its offset address, using the appropriate segment register.
Can I get free desktop downloads?
If it is just being accessed from memory, you better not change your wallpaper until you've used the "Print Screen" feature to save it some place else. Unfortunately, you are SOL on this one, since you've overwritten the original, (same as if it was deleted) there is no way to get it back or access its location directly from memory as you would if it was still stored in a folder.
