Disadvantages of memory segmentation:
External fragmentation is present
Costly memory management algorithms.
Segmentation finds free memory area big enough.
Paging keep list of free pages.
Segments of unequal size not suited as well for swapping.

8086 micro processor memory segmentation and advantage and rules?
hhh
How segmentation and pipe lining in 8086 are related to each other?
The process of dividing total memory sizes to the segment of various sizes is called segmentation. The device which is used to fetch,decode and execute is called pipe lining.
What is segmentation in computer memory?
memory segmentation is the process of dividing the computer memory into different overlapping segments.
What are the advantages AND disadvantages of geographic segmentation?
importance of geographic segmentation
What is segmentation in computer architecture?
Segmentation is part of physical memory ares.
Advantages and disadvantages of market segmentation?
what is the advanteges and dis advanteges of market segmentation?
Why memory to memory acess is not possible in 8086 micro processor?
Memory to memory access is certainly possible in the 8086/8088 microprocessor. Look at the repeated string copy instructions.
Write short notes on segmentation?
segmentation is scheme in which the logical memory is broken into a number of variable length blocks called SEGMENTATION.
Why you Use Memory Segmentation In 8086 Microprocessor?
The 8086/8088 is a 16 bit processor running on a 16 bit (8086) or 8 bit (8088) bus with a 20 bit address bus. In order to obtain the extra 4 bits of addressibility, Intel designed segment registers that are effectively multiplied by four and then added to the 16 bit offset address generated by the instruction. This yields 64K segments of 64KB each, although they overlap each other at a distance of 16 bytes.
Why 4 bit address bus is grounded?
The data bus in the 8086 is 16 bits in size, while the address bus is 20 (16bits would only address 64KB of memory, an extra 4 bits allows to address the total of 1MB, this is done trough segmentation of the memory). To form a multiplexed of data bus and address bus, four bits of 8086 address bus are grounded.
What is the highest memory address?
The highest memory address in the 8086/8088 is FFFFFH.
What is memory interfacing in 8086 microprocessor?
The 8086/8088 is a 16 bit computer running on a 20 bit address bus. Processes use a segmented memory architecture to access one of four 64kb memory segments from a physical space of 1mb.
