What is the IP pointing register's default memory segment?
CS
What is the SP pointing register's default memory segment?
The default segment for SP (Stack Pointer) relative memory accesses in the 8086/8088 is SS (Stack Segment).
A Explain the use of Code Segment CS and data segment DS register in 8086 microprocessor?
Code segment (CS) is a 16-bit register containing address of 64 KB segment with processor instructions. The processor uses CS segment for all accesses to instructions referenced by instruction pointer (IP) register. CS register cannot be changed directly. The CS register is automatically updated during far jump, far call and far return instructions. Data segment (DS) is a 16-bit register containing address of 64KB segment with program data. By default, the processor assumes that all data referenced by general registers (AX, BX, CX, DX) and index register (SI, DI) is located in the data segment. DS register can be changed directly using POP and LDS instructions. Code segment (CS) is a 16-bit register containing address of 64 KB segment with processor instructions.

What is the use of the extra segment in a 8086 processor?
extra segment is a 16-bit register containing address of 64KB segment, usually with program data. By default, the processor assumes that the DI register points to the ES segment in string manipulation instructions. ES register can be changed directly using POP and LES instructions. It is possible to change default segments used by general and index registers by prefixing instructions with a CS, SS, DS or ES prefix. any corrections most welcome
What is default port for ip?
TCP has no default port. Individual applications - such as FTP, DNS, or Telnet - do have default ports.
Why cant' a segment register be used as a byte register?
There are only a certain (few) number of operations that you can perform on a segment register. Specifically, you can push/pop, and move. That's it. Besides, arbitrarily manipulating segment registers will impact your execution environment - think about what could happen to your program if you changed CS - bad, very bad, unless you also changed IP - and that is called a far jump.
What is inter segment branch instruction?
The intersegment branch (or far branch) in the 8086/8088 is a branch where both the Instruction Pointer (IP) and the Code Segment(CS) registers are loaded at the same time. You can branch anywhere in memory with an intersegment branch. Contrast this with an intrasegment branch (or near branch) where only the IP register is loaded. Since the CS register is not loaded, the domain of the branch is only the 64kb segment currently selected by CS.
What are segment?
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.
