The status register holds the values of "flags" - bits indicating information about the state of the processor. Usually the bits indicate one of three possible outcomes of an arithmetic function: zero, carry, or overflow.
A "Zero" flag means that the result of an operation was "zero" - for example adding equal positive and negative numbers or that a logical evaluation returned a FALSE result.
A "Carry" flag can be used to allow operations on a data element comprised of more than one "word" by allowing an increment or decrement to be "carried" between a "word" of lower significant value and a "word" of higher significant value.
An "Overflow" flag is used to indicate that the results of an operation will not fit within the limits of a register width using twos complement representation.
Many systems also use the status register to indicate whether the result of an operation is negative or positive.
Some systems also have flags for overflow between 'nibbles' (half a byte), odd or even results, whether an operation is executing in 'supervisor mode', or interrupt enable bits.
All of these flags are normally set or cleared when an operation is completed. The register values can then be used to test for jumping/branching conditions.
The status register in a computer system is used to store information about the condition or state of certain aspects of the processor, such as arithmetic operations, overflow, and carry flags. It helps in determining the outcome of operations and controlling the flow of program execution based on the results of these operations.

Processor status word ( PSW ) in the case of 8085 refers to the collection of the values of the flag register and accumulator. It is used with the command push: PUSH PSW With this command, the proccessor saves the value of accumulator (A) and the values of the flag bits to the stack.
It is a memory register inside the CPU. The function is to hold the current microinstruction. The microinstruction is the bits that drive the control signal and drive the data path.
There is no PC register in the 8086/8088. It is called the IP register by Intel and it stands for the Instruction Pointer. It contains the address of the current/next instruction to be executed.
