In 8086 Carry flag, Parity flag, Ausiliary carry flag, Zero flag, Overflow flag, Trace flag, Interrupt flag, Direction flag, and Sing flag.

stack is portion of RAM used for saving the content of Program Counter and general purpose registers.

LIFO stacks, also known as "push down" stacks, are the conceptually simplest way of saving information in a temporary storage location for such common computer operations as mathematical expression evaluation and recursive subroutine calling.

IPV4 Internet Protocol Version 4 has 32 bits of address.

An interrupt which can be never be turned off (ie. disabled) is known as Non-Maskable interrupt

TRUTH TABLE FOR HALF ADDER

A    B  SUM  CARRY

0    0    0         0

0    1    1         0

1    0    1         0

1    1    0         1

INPLEMENTATION:

For SUM, The two inputs A and B are given to XOR gate.

For Carry, The two inputs A and B are given to AND gate.

In case of Move A to B it will move whatever the value of A into B.It mean it will move numeric, alphanumeric and alphabatic value.

In case of COMPUTE B=A it will assign the value of A into B. But in case of compute only numeric value will be compute.

Cache momory is a small high-speed memory. it is used for temporary storage of data & information between the main memory and the CPU(center processing unit). The cache memory is only in RAM.

Cache memory is random access memory (RAM) that a computer microprocessor can access more quickly than it can access regular RAM. AS the microprocessor processes data, it looks in the cache memory and if it finds the data there.
