The document provides an overview of key concepts in data communications including:
1. Data communication involves the transfer of data from one machine to another so that the sender and receiver interpret the data correctly. Protocols provide rules for different operating systems to share resources.
2. The effectiveness of data communication depends on delivery, timeliness, and accuracy of data transfer without errors or alterations.
3. Components of a data communication system include the message, sender, medium, receiver, and protocols governing the exchange.
4. Computer networks can be classified as local area networks (LANs), metropolitan area networks (MANs), or wide area networks (WANs) based on their size, geographic range, and
Computer network Introduction
This document provides an introduction to computer networks. It defines a computer network as a group of connected devices that can exchange data, such as computers, printers, and other nodes. Each node has a unique address. Networks use distributed processing to divide tasks among multiple computers, providing advantages like security, faster problem solving, and collaborative work. The basic elements of a computer network include at least two computers, a transmission medium, communication protocols, and network software. The document then discusses the history and applications of computer networks.
COMPUTER NETWORK
A computer network connects multiple devices using cables or wireless connections. There are several types of networks including LAN, WAN, MAN, and others. Networks can be configured in different topologies such as bus, star, or ring. Common transmission media for wired networks include twisted pair cables, coaxial cable, and fiber optic cables. Computer networks provide benefits like sharing resources and connectivity but also have disadvantages such as cost and potential single point of failures.
Network Fundamentals1.pptx
The document discusses different types of computer networks. It describes local area networks (LANs) as connecting hosts in a single office or building over short distances. Wide area networks (WANs) connect devices over longer distances, spanning towns, states or countries, and are typically run by telecommunications companies. Metropolitan area networks (MANs) provide connectivity over areas like a city or campus. LANs use switches to direct traffic to specific hosts, while WANs can be point-to-point connections between two devices or switched networks combining multiple point-to-point links.

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.
Computer network note
ARPANET was the first wide-area packet switching network developed in the late 1960s under the U.S. Defense Department to connect research computers and allow for more effective communication. It served as the basis for the modern Internet and implemented the TCP/IP protocol. A computer network connects computers together to share resources, data, and applications over various connection types. Key network components include network interface cards, servers, routers, bridges, hubs, switches, and gateways. Modern computer technologies that utilize networks include artificial intelligence, data science, the Internet of Things, blockchain, and edge computing.
