Here you will learn about difference between preemptive and non-preemptive scheduling in os. Preemptive Scheduling Preemptive Scheduling means once a process started its execution, the currently running process can be paused for a short period of time to handle some other process of higher priority, it means we can preempt the control of CPU from …

Here you will get program for hamming code in C and C++. Hamming code is a popular error detection and error correction method in data communication. Hamming code can only detect 2 bit error and correct a single bit error which means it is unable to correct burst errors if may occur while transmission of …
Here you get encryption and decryption program for hill cipher in C and C++. What is Hill Cipher? In cryptography (field related to encryption-decryption) hill cipher is a polygraphic cipher based on linear algebra. Invented by Lester S. Hill in 1929 and thus got it’s name. It was the first cipher that was able to …

Here you will get program for bucket sort in C and C++. In bucket sort algorithm the array elements are distributed into a number of buckets. Then each bucket sorted individually either using any other sorting algorithm or by recursively applying bucket sort. Take example shown in below image. Elements are distributed among buckets Then, …
Here you will get checksum program in C and C++. A checksum is a error detection method in Data Communication. It is used for errors which may have been introduced during transmission or storage. It is usually applied to an installation file after it is received from the download server. The actual procedure which yields …
Here you will learn about first fit algorithm in C and C++ with program examples. There are various memory management schemes in operating system like first fit, best fit and worst fit. In this section we will talk about first fit scheme. What is First Fit Memory Management Scheme? In this scheme we check the …
Here you will learn about best fit algorithm in C and C++ with program example. Memory Management is one of the services provided by OS which is needed for Optimized memory usage of the available memory in a Computer System. For this purpose OS uses 3 methods:- First Fit Best Fit Worst Fit In this …
Here you will get the program for caesar cipher in C and C++ for encryption and decryption. I will also list some of its advantages and disadvantages. What is Caesar Cipher? It is one of the simplest encryption techniques in which each character in plain text is replaced by a character with some fixed number of …
