ntel invented the 8051 architecture a long time ago, and garnered some hobbyist interest with the 8052BASIC chip, which contained a basic interpretter in masked ROM and allowed one to build a very small BASIC based computer. Since then the architecture has been licensed and/or stolen by MANY vendors, and good things have happened to it. It's been shrunk, expanded, speeded up, made lower power, had peripherals added, increased memory, flash and eeprom (and even ferromagnetic ram) added. Most variants are somewhat harder to find than PIC or AVR chips
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.
how temperature is measured using 8051 micro-controler?
A: Because it can only control 8 bits of data.

constructed on a single chip is called micro processor constructed on a single board is called micro controller
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...
the internal RAM is for data storage and for many applications is all that is needed.
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.
Well, honey, a PIC controller typically has a faster execution speed and lower power consumption compared to an 8051. Plus, PIC controllers often have a larger variety of peripherals and are more cost-effective for certain applications. But hey, at the end of the day, it all depends on what you need for your project, so pick your poison wisely.

There is no bootloader available for at89s51(atmel version of 8051)....bcos of absence of bootloader section in at8s51....but u can always use bootloader if u have p89vrs51...this is also an 8051 based controller but it has a bootloader section in it....
They are mainly four ports in 8051MC. port 0 port 1 port 2 port 3
