Justify that the virtual memory of 80386 is 64TB?
Max length of memory segment =4GB there r 8KB number of descriptor in GDT and 8KB in LDT . So total numbr of descriptors=16KB 4GB*16KB =64TB
What IC 80386 is?
The 80386 was a third generation version of the 8086/8088 microprocessor. The second generation was the 80286, adding protected mode. The 80386 added 32 bit mode, virtual 8086 mode, and flat 32 bit protected mode.The 80386 fixed the problem of the 80286 where existing object code was not compatible in protected mode because the meaning of the segment registers changed. The 80386 allowed the operating system to run in protected mode while presenting the process with a virtual 8086 environment where the segment registers worked as before. This was a stop-gap measure that worked until the full implementation of a true 32 bit flat memory model operating system and software.
What is the difference between 8086 and 8088 microprocessor regarding there pin diagram?
The differences are given below: 80286 1. Low data bus width (16 bit) 2. Returning from protected mode to real mode is hard and complicated. 3. Small RAM/Memory 80386 1. High data bus width (32 bit) 2. Easy for 80386 3. Big RAM / Memory (Real memory = 4GB and virtual memory= 64TB)
Difference between 8086 and 80386?
There are several differences between the 8086 and the 80386. Two notable differences: 1.) the 8086 is a 16 bit computer, while the 80386 is a 32 bit computer, and 2.) the 8086 does not support virtual addressing while the 80386 does.8086 is 8 bit processor and 80386 is 16 bit processor
What is the word size of the Intel 80386?
The Intel 80386 is a 32-bit processor.
Is it possible to interface more than 64K memory using 8085?
In order to interface more than 64K of memory using the 085, you would need an external address register, perhaps maintained by the 8255, which contained an offset register for part of the memory address space. This would be similar to how the 8086/8088 processors implemented expanded memory before using the 80386 and above processors.

How do you switch from real mode to protected mode in 80386?
To switch from real mode to protected mode in the 80386, set the PE bit in the MSW in CR0, and then immediately execute a JMP to flush the prefetch queue.
