wnenever a mechanical puch button is pressed or released once, the mechanical components of the key not changed the position smootly, it take some time to released it.this is c/as kydeboucning.
You will need a 8051 device programmer that connect to a PC with software to drive the programmer
The at89c52 are ones that are more advanced. This means that they are programmable compared to the 8051 which is not. So this makes a really big difference.
a powerful feature of 8051 I/O ports is their capability to access individual bits of the port without altering the rest of the bits in that port. of the four 8051 ports we can access either the entire 8 bits or any single bit without altering the rest
Are you referring to the original Intel 8051, or one of the many variants? The 8051 has weak internal pullups on the i/o pins, and can source only about 60 ua, but can sink 1.6 ma, still not much when it comes to driving the led in an opto. Some 8051-based dervatives can sink much more current. Atmel's 89C2051 for instance, can sink up to 20 ma per i/o pin. This can directly drive most optos.
In general, personal preference and experience is what it comes down to. There are some PIC's that have built in RF systems; I don't believe there are any 8051's with this capability.

how many interrupts in 8051
because i said so thats why
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
The 8051 is a micro-controller series, basically a computer on a chip. A system based on the 8051 series micro-controller is simply that, a device or series of devices that operate under control of one or more 8051 micro-controllers.
8051 is a CISC but having less number of instruction as comared to ARM which is RISC.CISC
how temperature is measured using 8051 micro-controler?

Atmel's family say that 8051 controller follows the von-nuemann architecture. because register to register operation not possible in all 8051 family. if it is harvard means, it must support register to register transfer.Hence it concludes that 8051 followed by von-nuemann or Princeton architecture...
