It's easy to understand and implement programmatically, using a Queue data structure, where a new process enters through the tail of the queue, and the scheduler selects process from the head of the queue.

First Come First Serve, is just like FIFO(First in First out) Queue data structure, where the data element which is added to the queue first, is the one who leaves the queue first.

In the "First come first serve" scheduling algorithm, as the name suggests, the process which arrives first, gets executed first, or we can say that the process which requests the CPU first, gets the CPU allocated first.

Longest Remaining Time First Scheduling.The Greedy Selection will be to assign least bit length program code to the most frequent personality. It assigns variable-length little bit codes to various figures.

The Greedy Choice can be to choose the advantage that attaches the two units and will be on the smallest pounds path from source to the place that includes not however integrated vertices.Ĥ) Huffman Code:Huffman Coding is usually a loss-less data compresion technique. We keep two models: a collection of the vertices already integrated in the sapling and the place of the vertices not really yet incorporated. The shortest path tree can be constructed up, advantage by advantage. The Greedy Selection is usually to choose the smallest weight advantage that attaches the two sets.ģ) Dijkstra's Shortest Path:The Dijkstra's algorithm will be very identical to Prim'beds criteria.

We sustain two pieces: a place of the vertices already incorporated in MST and the set of the vertices not really yet incorporated. 2) Prim's Minimum amount Spanning Shrub:In Prim'h algorithm furthermore, we generate a MST by picking edges one by one.
