What is the difference between context switch and process switch?
when ever an interrupt occurs, it saves the context of the program being executed & sets the PC to the starting address of the interrupt handling program. now after servicing the interrupt if the same process is resumed which was being interrupted then we will say a context switch has occurred.
But imagine after servicing the interrupt if a new process is to be executed then some more work is required, that is it has to save some more information from the PCB to keep reference to resume its execution and we say process switch has occurred..!!

after hr
A logical shift moves bits left or right. After a left shift, the high-order bit is lost while a zero is inserted in the low-order bit. After a right-shift, the low-order bit is lost and a zero inserted in the high-order bit. The left (<<) and right (>>) shift operators are binary operators; the first operand is the value being shifted, the second operand is the number of bit positions to shift. Thus x << y will left shifts all the bits of x by y bit positions.
Pass by value.

What are the disadvantages of low level language?
There are several disadvantages in low level programming languages

- It is very difficult to program in low level language.
- It is difficult to understand the pre-existing program if it is written in low level language.
- It is difficult to modify the program.
- It is difficult to debug the programs.
- It is difficult to fix the errors in the program.
- It is difficult to find and fix the semantic errors.
