Why 8051 is called 8 bit?
Because its a microcontroller with an 8 bit data bus width.
Explain about pin diagram of 8051 micro controller?
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 >>
What is mean by registers in micro controller?
Registers are a special type of memory that are dedicated to micro-controllers (or CPUs). Controllers have register-memory for speed.The slowest part of any computer is the bus. The bus is the wiring that connects different components. In this case the micro-controller and main memory. While main memory and the micro-controller are both very fast, the wiring between them is slow.Should the micro-controller have to be slow to compensate for the slow wiring?The solution is to have register-memory. Memory physically part of the micro-controller that allows the controller to use it instantly. The controller can then move data from a register to RAM as soon as the bus is available.Register-memory comes from the concept of a Cash Register [1879]. A cash register is used to perform transactions and store money on it's way to a vault the same way a CPU or micro-controller stores data on its way to main memory.
Is 8051 programming is a programming language?
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.
What is the external data memory capacity of 8051 and why?
65536 bytes, because the 8051 family has a 16 bit external address buss.
Why 8051 is called 8 bit micro controller?
A: Because it can only control 8 bits of data.
What is purpose of ram in 8051 micro controller?
the internal RAM is for data storage and for many applications is all that is needed.
Why the frequency is 11.059 Hz in 8051 micro-controller?
First let me make you correct it's not 11.059 Hz it's 11.0592 MHz and we select? this crystal because it makes 8051 Microcontroller to be compatible with IBM standard PC(baud rate 9600) to transfer data.

What is fullform SBUF?
if you are talking about micro controller, it is "serial buffer". it is used to store the the data if RAM is full! just like queue.

What is buffer in microprocessor?
By using buffer along with micro-controller, it is possible to reduce the effect of 'back EMF' or 'Spiking Effect'. The capacity of any micro-controller is to sink or source current up to 25mA and its ports gets damaged if it is more. So buffer protects ports of micro-controller getting damaged. And it is possible to get appropriate data trans-receiving by using buffer in micro-controller.Sachin Joshi
What does data Controller mean?
A data controller is a person who controls the data.
How do you determine which pin on a micro controller is analog or digital?
just check data sheet of the ic and you will get relevent information more than you want
How many address lines and data lines there in 8051?
12
