This passage will elaborate on Qos definition, its indicators and advantage in terms of network bandwidth allocation. Network devices may be inter-network or intra-network. Create files and store them in one computer, access those files from the other computer (s) connected over the network. The levels are: Data link level - e.g. A computer network is a collection of two or more computer systems that are linked together. An introduction to network topology. These have the address of all hosts stored, as well as the host which is . They can range from simple networks consisting of two computers to networks connecting millions of devices. What started as a series of "hello world" examples has evolved into an entire discipline with books, professional certifications and dedicated career paths. On an internet, each host has an address of the form n/h where n is the network number and h is the number of the host on network n. Here are a few terms to get started: A network: A group of devices that can communicate with each other over links. Each host has a unique address . The term "network infrastructure" refers to all the different components that go into building a computer network. Usually there can be from 2 to hundreds or even thousands of computers on the network. An introduction to networking 1. LAN. There are . Some devices are installed on the device, like NIC . Each of these links can be present or absent, so there are 2. Listen. Resource sharing: Resource sharing is the sharing of resources such as programs, printers, and data among the users on the network without the requirement of the physical location of the resource and user. We use a WAN connection to reach other remote LANs or servers on . Connect a printer, scanner, or a fax machine to one computer within the network and let other computers of the network use the machines . . Learn to perform basic computer networking tasks such as DSL connectivity, configuring connections to an ISP and creating a private network. Security and reliability will be very important (minimize false alarm or misalarm) Home networks may be wired or wireless A computer network comprises two or more computers that are connectedeither by cables (wired) or WiFi (wireless)with the purpose of transmitting, exchanging, or sharing . They need to speak the same language. The purpose of having computer network is to send and receive data stored in other devices over the network. Major concepts, such as OSI and TCP/IP models, network . Computer networking refers to interconnected computing devices that can exchange data and share resources with each other. It should be attempted on question paper and returned to the supervisory staff after the prescribed time. 9.4 Dynamic Host Configuration Protocol (DHCP) 9.5 Domain Name System. Network hardware uses cables to connect the different devices (for a wired network) and junction boxes like routers, switches, and gateways. Computer networking involves the linking of different computer devices (known as hosts) by others and interfaces designed to ensure effective connection, security, and sometimes, integrity.
