| Maybe RS232 is the common way to solve your topic. And u can find the program anywhere.

If you can, I would ecourage you to build/buy a development board with RS-232 port ( http://www.pjrc.com/tech/8051/board3/schematic.html ) which includes some very usefull additional features such as for example SRAM ..
Using a monitor program you will be able to upload/download contains of this SRAM, run programs dowloaded to SRAM and many more ..
Check out this link:

try first the parallel port instead of the serial just to get used to the interfacing as parallel is easier to understand and in assembly is easier to get data, serial is more complex in acquiring data as you have to wait that buffer is full and respond to the interrupt, more work
enjoy

RS232 interface can generate interrupts and it needs few wires, but it will cost more because of a external RS232 level -shifter (such as max232) is needed.
parallel port need almost no externel components, but it is diffcult to handle the realtime applications because of no interrupt will be generated if you use the parallel port.

hi,
concern the following program and circuit
ORG 30H
INI:
MOV TMOD,#21H
MOV TH1,#0A0H ;9600 BAUD
MOV SCON,#50H ;8 BIT UART MODE
MOV TH0,#HIGH(-50000)
MOV TL0,#LOW(-50000)
SETB TR1
MAIN:
JB RI,SERIAL
JMP MAIN
;==================
SERIAL:
CLR RI
MOV A,SBUF

Assalamo Allykum !
You can do this by using parallel port as well as serial port.
But asyou are new to Microcontroller then use Parallel port for your convenience, and usr At89C52 rather than AT89C51, because of memeory size because you are interfacing the data transfer from the PC.
www.8052.com
it is a good site and it will help you a lot.
TAke CAre
Wish you a good luck.

| it is simple just put a mediator between 8051 and PC that is max232 IC and connect it to PC this will do the job

Assalam
Akbar, better u ask this question in new topic ....
because the ATKeybaord is working on I2C protocol having data clk Vcc GND lines
please check the following website

| first try to understand at what protocal does the keyboard works then by using the 8051 core i think it is possible to communicate the micro controller with the computer keyboard
