What is the computer system which is connected for sharing of data?
A computer network is a system that connects numerous independent computers in order to share information (data) and resources. The integration of computers and other different devices allows users to communicate more easily. Show Criteria of good network:
Goal Of Networking:
Types of NetworksDivision based on the communication medium
Division based on area covered
Point To Point: Connects two connecting devices through transmission media. Switched: A switched WAN is a network with more than two ends. Based on types of communication
Based on the type of architecture
Network Topology1. Bus Topology: Every computer and network device is connected to a single cable in a bus topology network. Linear Bus topology is defined as having exactly two terminals. Advantages
Disadvantages
2. Ring Topology: The topology is named ring topology because one computer is connected to another, with the final one being connected to the first. Exactly two neighbors for each device. A signal is passed along the ring in one direction. Each ring incorporates a repeater. Advantages
Disadvantages
3. Star Topology: Each device in a star topology has a dedicated point-to-point link to a central controller, which is commonly referred to as the HUB. There is no direct connection between the devices. Traffic between the devices is not allowed in this topology. As an exchange, the controller is used. Advantages
Disadvantages
Example: Used in high-speed LANs 4. Mesh Topology: Every device in a mesh topology has dedicated point-to-point connectivity to every other device. The term “dedicated” refers to the fact that the link exclusively transports data between the two devices it links. To connect n devices, a fully connected mesh network contains n *(n-1)/2 physical channels. Advantages
Disadvantages
Example: connection of telephone regional office in which each regional office needs to be connected to every other regional office. 5. Tree Topology: The topology of a tree is similar to that of a star. Nodes in a tree, like those in a star, are connected to a central hub that manages network traffic. It has a root node, which is connected to all other nodes, producing a hierarchy. Hierarchical topology is another name for it. The number of Star networks is connected via Bus in Tree Topology. Advantages
Disadvantages
Networking DevicesBasic hardware interconnecting network nodes, such as Network Interface Cards (NICs), Bridges, Hubs, Switches, and Routers, are used in all networks. In addition, a mechanism for connecting these building parts is necessary, which is usually galvanic cable and optical cable are less popular (“optical fiber”)The following are the network devices :
InternetThe internet is a larger network that allows computer networks controlled by enterprises, governments, colleges, and other organizations all over the world to communicate with one another. As a result, there are a tangle of cables, computers, data centers, routers, servers, repeaters, satellites, and wi-fi towers that allow digital data to go around the world. The Internet is a vast network of networks that functions as a networking infrastructure. It links millions of computers throughout the world, creating a network in which any computer can talk with any other computer as long as they are both linked to the Internet. The Internet is a global network of interconnected computers that communicate and share information using a standardized Internet Protocol Suite. Sample QuestionsQuestion 1: List the advantages and disadvantages of the internet. Solution:

Which is used to share the data of the computer?A computer network or data network is a telecommunications network which allows computers to exchange data. In computer networks, networked computing devices exchange data with each other using a data link. The connections between nodes are established using either cable media or wireless media.
What is the system of many computers connected together to share information called?A computer network is a set of computers connected together for the purpose of sharing resources. Computers and devices that allocate resources for a network are called servers. Computer networks support an enormous number of applications and services such as access to the World Wide Web and digital video.
What is the system of connected computers?Transmission Control Protocol/Internet Protocol (TCP/IP) is a suite of protocols used by all computers connected to the Internet to communicate with each other. You can think of the Internet as a big network of computers and other devices connected to it.
Which devices are shared in a computer network?Computer networks share common devices, functions, and features including servers, clients, transmission media, shared data, shared printers and other hardware and software resources, network interface card(NIC), local operating system(LOS), and the network operating system (NOS).
