How many register in 2K memory chip?
Registers represent the number of memory locations. A 2K memory chip has 2x1024=2048 memory locations. Hence there are 2048 registers in a 2K memory.
What is data segment memory and code segment memory?
Code Segment, in which all the application code is stored Data Segment, that holds the global data
What are registers in assembly language?
Registers are memory locations on the microprocessor itself (not in main memory). In RISC architectures generally most operations (add, multiply, etc) must take there input from registers and write their output to a register. Since registers are located directly on the microprocessor, they represent the fastest form of memory in the computer, and also the type of memory available in the least quantity.
What is the difference between register stacks and memory stacks?
Registers are normally memory spaces internal to the processor or very close to it. They are generally faster than main memory and will be small in size and will hold very frequently used data.Register stacks are a set of such register memory locations.Memory refers to computers main memory outside CPU. It is used to keep data and programs. Memory stack is a series of memory locations.The difference between register stack and memory stack is...

What are segment registers?
In the x86 processor architecture, memory addresses are specified in two parts called the segment and the offset. One usually thinks of the segment as specifying the beginning of a block of memory allocated by the system and the offset as an index into it. Segment values are stored in the segment registers. There are four or more segment registers: CS contains the segment of the current instruction (IP is the offset), SS contains the stack segment (SP is the offset), DS is the segment used by default for most data operations, ES (and, in more recent processors, FS and GS) is an extra segment register. Most memory operations accept a segment override prefix that allows use of a segment register other than the default one.

How does an 8088 microprocessor generate physical address?
8086 has memory divided into segments.Each segment has its particular register like ES, DS, SS, CD (extra segment, data segment, stack segment and code segment).These registers hold the base address BA.Now, there two base registers(BX and BP) and two index registers(SI and DI) in 8086. These registers hols the effective address EA.Now Physical address PA is sum of EA and BA.That is,PA = BA+EA
What are the function of segment register?
The segment register in the 8086/8088 provide a base address for any memory access. There are four segment registers, CS - Code Segment, DS - Data Segment, SS - Stack Segment, and ES - Extra Segment. Each in used in the context of a particular instruction and contains the base address of the memory segment divided by 16. This allows the processor to access up to 1 MB of memory, though only in segments of 64 KB at a time.
