Quantum computing is a cutting-edge field of computer science that harnesses the principles of quantum mechanics to perform computations. Unlike classical computers, which use bits as the basic unit of information (0 or 1), quantum computers use quantum bits or qubits. Qubits can exist in a superposition of states, representing both 0 and 1 simultaneously,…
Virtualization is the process of creating a virtual, rather than physical, version of something, such as an operating system, server, storage device, or network resource. This technology enables multiple virtual instances to run on a single physical machine, allowing for more efficient utilization of hardware resources. In computing, virtualization is primarily used to: Types of…
Cloud computing refers to the delivery of computing services—such as servers, storage, databases, networking, software, and analytics—over the internet (“the cloud”) to offer faster innovation, flexible resources, and economies of scale. It typically involves renting resources rather than owning them outright. With cloud computing, users can access computing power and data storage on-demand, without needing…
Binary code is the language of computers, representing data and instructions using only two symbols: 0 and 1. It is the foundation of all digital technology and forms the basis of how computers store, process, and transmit information. Each digit in binary code is called a “bit“. which is a contraction of “binary digit.” Just…
Wireless communication refers to the transmission of data or information without the use of physical wires or cables. It utilizes electromagnetic waves such as radio frequencies, microwaves, or infrared light to carry signals between devices over varying distances. Wireless communication enables devices to communicate with each other remotely, facilitating connectivity and data exchange in various…
Point-to-Point Protocol (PPP) is a communication protocol commonly used in computer networking to establish a direct connection between two nodes, typically over a serial communication link. PPP is often employed for connecting a computer (or network of computers) to the Internet through a dial-up connection or other types of point-to-point links. PPP provides a standard…
A common network protocol called File Transfer Protocol (FTP) is used to move data over a computer network between a client and a server. One of the first protocols created for the internet was intended to make file transfers between various systems more effective. FTP uses a client-server architecture, in which a single computer serves…
Telnet, short for Telecommunication Network, is a protocol used for connecting to remote computers over a network, typically the Internet. It allows users to access a command-line interface on a remote host and execute commands as if they were directly connected to that host. A client and a server create a connection for Telnet to…
Internet Protocol, commonly known as IP, is a fundamental communication protocol that facilitates the exchange of data across networks, forming the backbone of the modern Internet. It serves as a set of rules and conventions governing how devices on a network identify and communicate with each other. The primary function of IP is to enable…
The World Wide Web (WWW), commonly known as the Web, is a global system of interconnected documents and resources that are accessed via the Internet. It is a vast information space where users can browse and interact with content using web browsers. The concept of the World Wide Web was introduced by Sir Tim Berners-Lee…
