  Top 8051 Microcontroller Interview Questions And Answers      1. What is 8051 Microcontroller ? Answer: The Intel 8051 microcontroller is one of the most popular general-purpose microcontrollers in use today. It is an 8-bit family of microcontroller developed by Intel in the year 1981. This microcontroller was also referred to as “system on a chip” because it has 128 bytes of RAM, 4Kbytes of ROM, 2 Timers, 1 Serial port, and four ports on a single chip. 8051 microcontroller allows CPU to work on 8bits of data at a time.n case the data is larger than 8 bits then it has to be broken into parts so that the CPU can process conveniently. 2. What are applications of 8051 microcontrollers? Answer: The constant growth in information technology has provided many benefits of making use of a microcontroller, integrated circuits, embedded chips, microprocessors, etc. With these technologies, work is done faster and complexity is reduced. The 88051 microcontrollers are used in electronic and
