The 8051 is a microcontroller, not a microprocessor. To add or subtract, use the ADD or SUBB opcodes.

disadvantages:1.It has limitations on the size of data. 2.Most Microprocessor does not support floating-point operations. 3.over heating physically, 4. not bit addressable,
OTP 8051 refers to a specific type of microcontroller based on the 8051 architecture, which is programmed using One-Time Programmable (OTP) memory. This means that once the program is written to the chip, it cannot be modified or erased, making it ideal for applications where the code is finalized and will not need updates. OTP 8051 microcontrollers are commonly used in embedded systems for tasks like control, automation, and data processing. Their limited reusability is compensated by their reliability and simplicity in design.
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.
the 8051 microcontrroller is the name doesnt matter easy or not....but the maiin and imp diff between both is at89s51 represents the 8051 chip no....along with the name of company i.e atmel, so all n all both are same thing ...... 89c51 have RISC architecture and contains less no of opcodes which are easy for programming. so iti is preferred than 8051.

write it in 8085
8 bit
how temperature is measured using 8051 micro-controler?

hai
b/c the 8085 microprocessor is the first 8 bit microprocessor which Intel is produces in 1877 and this is the first general purpose 8 bit microprocessor. there was an 8 bit general purpose register before 8085 named as 8008 but this microprocessor is not functional 8 bit microprocessor

there are 74 instruction sets in the 8085 up which consist of 246 bit pattern.
how many interrupts in 8051
because i said so thats why
