A network is a collection of computers and devices connected together so that data can be shared between them. Even a single computer can be considered part of a network when connected to the internet, as the internet itself is a network of networks. Computer networks typically connect devices physically using cables, or wirelessly, and use IP addresses to identify each other. Personal area networks connect devices close to an individual, like between a phone and laptop, while local area networks connect devices in a small area like a building. Metropolitan and wide area networks connect across larger distances.

Data Communication & Network
Computer networks can be classified based on their geographical span, interconnectivity, administration, and architecture. They range from personal area networks (PANs) covering 10 meters around a device, to local area networks (LANs) within a building, to metropolitan area networks (MANs) within a city, to wide area networks (WANs) spanning countries, to the largest network, the internet, which interconnects networks worldwide. Networks allow sharing of resources like printers and storage, as well as exchange of information via email, webpages, and other applications.

Computer networking
A computer network connects multiple devices together to share resources. The main advantages of a network include resource sharing, reliable data storage through backups, and centralized storage of files. There are different types of networks including personal area networks (PANs), local area networks (LANs), metropolitan area networks (MANs), and wide area networks (WANs). Networks require transmission media like cables or wireless signals to connect devices and transfer data. Common network devices that help facilitate networking include network interface cards, hubs, switches, repeaters, and routers.
Computer Network Second Edition
ARPANET was the first wide-area packet switching network developed in the late 1960s under the US Advanced Research Projects Agency (ARPA). It served as the basis for today's internet by linking computers located at Pentagon-funded research institutions. A computer network connects computers together to allow for sharing of resources like files, printers or internet access. The main types of computer networks are LAN, PAN, MAN and WAN, which differ based on the maximum distance they can connect and examples of each are provided.

This document provides an overview of computer networking concepts. It defines a network as any collection of independent computers that communicate over a shared medium. The key types of networks discussed are LANs (local area networks connecting devices within a short distance), MANs (metropolitan area networks spanning a city), and WANs (wide area networks extending long distances using various communication lines). The document also outlines common networking devices, terminologies, and the needs and advantages that networks provide for resource sharing, communication, and accessing remote databases.

10 New Web Application and Security.pptx
Web application security is the process of protecting websites and online services against different security threats that exploit vulnerabilities in an application’s code . Common targets for web application attacks are content management systems Web application security is important to any business as it helps to keep web applications functioning smoothly and protect businesses from cyber vandalism, data theft, unethical competition, and other negative consequences . Web applications may face a number of attack types depending on the attacker’s goals, the nature of the targeted organization’s work. A web application (web app) is an application program that is stored on a remote server and delivered over the internet through a browser interface. Web services are web apps by definition and many, although not all, websites contain web apps.

A computer network is a digital telecommunications network that allows network nodes to share resources. In computer networks, computer devices exchange data with each other using connections (data links) between nodes. These data links are established via network cables such as wire or fiber optics , or wireless media such as Wi-Fi .
Network computing devices that launch, route , and terminate data are called network nodes. [1] Nodes are often identified by network addresses and can include network hosts such as personal computers , phones , and servers , as well as network hardware such as routers and switches. Two such devices can be said to be interconnected when one can exchange information with the other, whether they are directly connected to each other or not. In most cases, application-specific communication protocols are layered (i.e., carry a payload ) over other general communication protocols . This formidable collection of information technology requires skilled network managers to keep all network systems running well.
Class viii ch-1 networking concepts
This document provides an overview of computer networking concepts. It defines a computer network as a group of computers that are connected together to share data and hardware resources. The main components of a network include network interface cards, cables, hubs, switches, and wireless access points. There are several types of networks defined by their size, such as personal area networks, local area networks, metropolitan area networks, and wide area networks. Network topologies determine how devices are arranged and connected, and common topologies include star, ring, bus, and mesh. Security measures like login credentials and access rights help control unauthorized access to network resources.

The document provides an overview of the history and components of the Internet. It discusses how the Internet originated from separate computer networks established by the US government in the 1960s to share information. The networks eventually merged and adopted common communication protocols, marking the birth of the Internet in 1983. The key components that enable the functionality of the Internet are packets, which break up data for transmission, and protocols, which allow different systems to communicate. The document also outlines several hardware components that make up networks, including modems, routers, firewalls, hubs, switches, and wireless access points.

A computer network connects two or more computers to allow sharing of resources and communication. It can be a local area network (LAN) spanning a single building, or a wide area network (WAN) across continents. The main components are computers, cables or wireless connections, network cards, and network operating software. Computer networks provide benefits like sharing hardware and software, communication, and accessing data remotely, but also have disadvantages such as high installation costs and potential points of failure. Networks can be organized as peer-to-peer, with each computer sharing directly, or client-server with dedicated server computers providing centralized resources to client computers. Common network types include LANs, WANs, MANs, PANs, and
