What is the purpose of segment registers?
It is basically used to enhance the speed of execution of the computer system, so that the processor is able to fetch and execute the data from the memory easily and fast. The Bus Interface Unit (BIU) contains four 16 bit special purpose registers (mentioned below) called as Segment Registers.
What is the purpose of segment registers in 8086 register?
The segment registers of 8086 are: CS (Code Segment): Code segment (CS) is a 16-bit register that is used for addressing memory location in the code segment of the memory (64Kb), where the executable program is stored. 8086 has eight general purpose registers.
How many types of segment registers are there?
2) Segment Registers There are 4 segment registers in 8086 Microprocessor and each of them is of 16 bit. The code and instructions are stored inside these different segments.
What are segment registers explain with example?
Segment Registers A 16-bit Code Segment register or CS register stores the starting address of the code segment. Data Segment − It contains data, constants and work areas. A 16-bit Data Segment register or DS register stores the starting address of the data segment. It is implemented as a ‘stack’ data structure.
Why extra segment is used?
The es (Extra Segment) register is an extra segment register. 8086 programs often use this segment register to gain access to segments when it is difficult or impossible to modify the other segment registers. The ss (Stack Segment) register points at the segment containing the 8086 stack.
What is market segmentation advantages and disadvantages?
(i) The marketer can spot and compare marketing opportunities. Differences in customer response to different marketing tools serve as the basis for deciding on the allocation of market funds to different customer groups.

- Difficulty in Distribution:
- Heavy Investment:
- Promotion Problems:
- Stock and Storage Problems:
What are the advantages and disadvantages of paging over segmentation?
The biggest advantage of paging is that it is easy to use memory management algorithm. Paging may cause Internal fragmentation. Segmentation method works almost similarly to paging, only difference between the two is that segments are of variable-length whereas, in the paging method, pages are always of fixed size.
