SESSION 1 (8051 MICRO-CONTROLLER)

                                     Lets begin session(1) with 8051 micro controller.                       

For  deep knowledge you can follow the above link .All details are available  in this link.

Basic description about 8051 micro controller is given below-

8051 – This version of micro-controller is cheaper and available from various manufacturers. The manufacturers use  micro-controller for mass production because the price per unit is very cheap.

The main features of 8051 micro-controller are:               
  

  • RAM – 128 Bytes (Data memory)  
  •  ROM – 4Kbytes (ROM signify the on – chip program space)    
  • Serial Port – Using UART makes it simpler to interface for serial communication
  • Two 16 bit Timer/ Counter
  • Input/output Pins – 4 Ports of 8 bits each on a single chip.
  •   6 Interrupt Sources
  •   8 – bit ALU (Arithmetic Logic Unit)
  •   Harvard Memory Architecture – It has 16 bit Address bus (each of RAM and ROM) and 8 bit Data Bus.
  • 8051 can execute 1 million one-cycle instructions per second with a clock frequency of 12MHz

what do you think about IOT?

Internet of thing (IOT) is a technology connecting devices,machines,tools to internet by means of wireless technologies. Over 9 billion things connected to internet,as of now. Things connected to the internet are projected to cross 20 billion in the near future. In future  IOT market share will increase to high level. Day by day  companies and developers are working on it .Now every thing is developing. Machines are doing work automatically and we can control them by our smart phone ,tablet from any where in this  earth. Because of Iot we can say that we are living in a new world where without men power we can control a machine . Our homes are also becomes smart .By using IOT our home doors are becomes automatic,we can control our ac and fans by our own smart phone , we can operate our washing machine ,water motor and geyser from our office/work place. #reference-nptel online cousre
