Networking

A  computer network  is a set of connected computers. Computers on a network are called  nodes . The connection between computers can be done via cabling, most commonly the Ethernet cable, or wirelessly through radio waves. Connected computers can share resources, like access to the Internet, printers, file servers, and others. A network is a multipurpose connection, which allows a single computer to do more. Computer networks can be broken down historically into  topologies , which is a technique of connecting computers. The most common topology today is a  collapsed ring . This is due to the success of a network protocol called the Ethernet. This protocol, or a network language, supports the Internet, Local Area Networks, and Wide Area Networks.  A  star topology  is a design of a network where a central node extends a cable to each computer on the network. On a star network, computers are connected independently to the center of the network. If a cable is broken, the other comput

Operating system

Now we are going to explain the basics of OS.This is an interface between a computer user and hardware.It is very important as it works as a middleman making sure both hardware and sogtware.Correctly there are 4 essential managers of every OS and they all coork together like team to get jobs completed. First, Memory managment is the function that controlling and coordinating memory location and either allowsted or free blocks to varoius programms to optimize overall system perpormance.These are 4 types of technique ways to manage memory 1. Single configous allocation. 2. Partiction allocation 3. Paged memory management 4. Segmented memory management all this techniques has their own advantages on their own. In hardware memory management involves components that physically store data such as RAM(Random access Memory ), VRAM(Virtual Random Access Memory), GRAM(Graphic Random Access Memory) chips, memory caches and flash based SSPs(Sold Store drives) Part1: The basic unit of softw

Modern iT trends

Information technology IT is the application of computers to store, study, retrieve, transmit, and manipulat   data or information, often in the context of a business or other enterprise.   IT is considered a subset of information and communications technology ICT. In 2012, Zuppo proposed an ICT hierarchy where each hierarchy level "contain[s] some degree of commonality in that they are related to technologies that facilitate the transfer of information and various types of electronically mediated communications. - Open philosophies Open development breaks the data center down into its lowest-level components, which fit together by open standards. Still, with less than 2% of enterprise applications designed for horizontal scaling, enterprise IT should avoid lifting legacy apps onto open infrastructure. Instead, put new workloads on building-block infrastructure, and renegotiate your hardware contracts to get ready for more open-standard hardware and software. - Software-defi
