Hello and welcome you all to this new video. So SJF or Shortest Job First is also a CPU scheduling algorithm. As the name suggests it prioritizes scheduling based on the burst time. So the process that needs less execution time will be scheduled first. It significantly reduces the average waiting time problem that we face in first come first serve scheduling algorithm. It is a solution on convo...

Hello and welcome you all to this new video on my channel making it simple. So there are many scheduling algorithms, each work on different scheduling principle, basically that means which process will get executed by CPU and in which order. FCFS, our today’s algorithm schedules the process based on their arrival time. Similar to ticket counter, whoever will come first will be sent for the CPU ...

Hello Guys! We know that a database table can have n number of records present. If this data is not well organized or if it contains redundant data. Data manipulation like insertion, updation or deletion on such tables can cause various anomalies or problems. Solution on these anomalies is the process called normalization. This normalization process is used to remove or minimize the redundancy ...
