It is program status register.It i 8 bit ,bit addressable register.It consists of four maths flag.
Intel
The microcontrollers have an 8-bit data bus. They are capable of addressing 64K of program memory and a separate 64K of data memory. The 8051 has 4K of code memory implemented as on-chip Read Only Memory (ROM). The 8051 has 128 bytes of internal Random Access Memory (RAM). The 8051 has two timer/counters, a serial port, 4 general purpose parallel input/output ports, and interrupt control logic with five sources of interrupts. Besides internal RAM, the 8051 has various Special Function Registers (SFR), which are the control and data registers for on-chip facilities. The SFRs also include the accumulator, the B register, and the Program Status Word (PSW), which contains the CPU flags. << SHARMILA TANDEL (B.E) ELECTRONICS >>

65536 bytes, because the 8051 family has a 16 bit external address buss.
You need a reset circuit in the 8051, as in every logic circuit, in order to ensure that it starts up in a known state.

Psw is a file format associated with programs. Microsoft uses the .psw file format. It can be used in mobile word processing.

how many interrupts in 8051
because i said so thats why
A PSW makes about 18 dollars an hour to start but that can vary.
What is the role of a PSW helping a person with down syndrome
avr is high speed cmpar to 8051.in 8051 there are less number of instructions
The 8051 runs on +5vdc.

Yes, 8052 family is upgraded version of 8051 family
