Regression Testing

Image
  Regression Testing – Software Engineering       Regression Testing is the process of testing the modified parts of the code and the parts that might get affected due to the modifications to ensure that no new errors have been introduced in the software after the modifications have been made. Regression means the return of something and in the software field, it refers to the return of a bug.

Explanation of what is Basic Blocks of computer. Block Diagram of Computer   Hello friends! in this article, we will explain the block diagram of a computer and its various components. With technology upgrading rapidly, now computers have now become part of our daily lives. From performing basic operations like watching a movie to high-level functions like manufacturing a car. The computers are doing it all. But have you ever thought about how does a computer works? What processes go inside it?  What are the fundamentals of a computer? Just like the other machines, the computer has also a basic architecture. It comprises multiple elements. These elements process the input and produce the desired output.  Let us look at the basic block diagram of the computer.Then, we will understand how each part contributes to its functioning.   Block Diagram of a Computer  Input  All the data received by the computer goes through the input unit. The input unit compr...

what is topology in networking and their uses in practical life with example

Image
  A Network Topology is the arrangement with which computer systems or network devices are connected to each other. Topologies may define both physical and logical aspect of the network. Both logical and physical topologies could be same or different in a same network. Point-to-Point Point-to-point networks contains exactly two hosts such as computer, switches or routers, servers connected back to back using a single piece of cable. Often, the receiving end of one host is connected to sending end of the other and vice-versa. If the hosts are connected point-to-point logically, then may have multiple intermediate devices. But the end hosts are unaware of underlying network and see each other as if they are connected directly. Bus Topology In case of Bus topology, all devices share single communication line or cable.Bus topology may have problem while multiple hosts sending data at the same time. Therefore, Bus topology either uses CSMA/CD ()technology or recognizes one host as Bus ...
