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 >>

its a 40 pi ic chip

The Pic Controller has many advantages over a 8051. The main advantage is the editing capabilities. Another advantage is the high resolution.
Answer It is both 8 bit processors in a 40 pin package but it is not pin compatible, it have almost the same functions but it is very difficult to compare the two because it is not the same family.
See the related link below. It is build by using 8051 microcontroller, you can also get the source code from there.
8051 programming refers to the Intel 8051 micro-controller. This is a small computer on a single chip having electronic input output that is used to control simple machinery.The 8051 uses an instruction set consisting of binary codes and data that may be used to describe the algorithms that the microprocessor runs. These instructions are published by Intel with a set of mnemonic words that are designed to enable the programmer to remember the instructions. These mnemonics are not part of a formal programming language because they have no syntax apart from the instruction and data values for each command that the processor might execute.The instructions could be placed in any order such that no particular algorithm is expressed.A formal programming language however requires structure and syntax that describes the algorithm as an abstract concept apart from the system that might run the program. A programming language, such as C, C# or Java will be portable across machines but 8051 assembly code will only run on that processor.In short then, the 8051 assembly code is not a programming language as such.
how temperature is measured using 8051 micro-controler?
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.
constructed on a single chip is called micro processor constructed on a single board is called micro controller
A: Because it can only control 8 bits of data.

the internal RAM is for data storage and for many applications is all that is needed.
the 8051 is a micro controller the buttons tell the 8051 to do something there is an ir led on an output bit of the 8051 that shines on the tv ir detector it pulses a code the tv knows or window fan, ac , vcr, dvd the other output bits are used to scan multiple buttons like the difference between a rotary and touch tone Phone ive seen them with tms1000 and z8 thermostats may have 68hc11 it has 8 channel a/d right on it circuit diagram is very trivial its all in how you pulse the led
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.

They are mainly four ports in 8051MC. port 0 port 1 port 2 port 3
Draw the pin diagram of 8051 and explain the functioning of each and every pin.
