What is verification in software testing ?Verification in software testing is a process of finding whether or not the output of a particular phase of SDLC meets the implementation steps. It is process oriented here the major concern is to ensure that                                                                         “ Are we building the product right ?”During verification process in software testingwe mainly check that whether or not all the requirements are listed properly.

File management in operating systemToday in this post I am going to discuss about file concept in os and file management in operating system. In this post we will learn about different types of files in operating system.What is file ?Generally  a file is a collection of records. A file can also be defined as a named persistent sequential (structured) data repository. The basic idea behind the creation of a file is  that files can be used to store data for long periods of time, and specifically.  File as a collection of related information is recorded on the secondary storage like magnetic disk. Magnetic tape and optical disk.Attributes of file Under this heading we will learn ...

What is thrashing ?Today I am going to introduce about thrashing in os. So what is thrashing in os ? Thrashing is a state which occurs when a process is spending more time in paging or swapping than its execution. In thrashing state CPU is so much busy in swapping that it can not respond to user program as much as it required.Causes of ThrashingThrashing is not good for performance point of view. Now I will tell about the causes of thrashing actually Initially when the CPU utilization is low, then process scheduling mechanism, loads multiple processes into the memory at the same time in order to increase the degree of multi programming.So now in this situation we have more number of processe...

Cache Mapping TechniquesToday in this cache mapping techniquesbased tutorialfor Gate  we will learn about different type of mapping techniques used in cache memory. These techniques are used to fetch the information from main memory to cache memory. There are three type of mapping techniques used in cache memory. Let us see them one by oneThree types of mapping procedures used for cache memory are as follows -(i) Associative mappingThe fastest and most flexible computer used associative memory in computer organization. The associative memory stores both the address and content (data) of the memory word. This permits any location in cache to store any word f...
