Computer Networks
Network is between two or more computers connected each other they can exchange data. For example a network allows computers to share files, users to message each other. Computer network topology is the way various components of a network for example (link, connect) which is different systems and nodes are connected and communicate with each other.
A network is a set of devices, software, and cables that enables the exchange of information between them. Host devices are computers, servers, laptops, Personal Digital Assistants (PDAs), or anything a person uses to access the network. A topology describes the layout of a network. There are several topologies (Star, Ring, Bus and mesh).
A Computer network consists of

LAN configuration consists of:
O A file server - stores all of the software that controls the network, as well as the software that can be shared by the computers attached to the network.
O A workstation - computers connected to the file server (Mac or PCs). These are less powerful than the file server
O Cables - used to connect the network interface cards in each computer. METROPOLITAN AREA NETWORK (MAN)
Metropolitan Area Network (MAN) covers larger geographic areas, such as cities. Often used by local libraries and government agencies often to connect to citizens and private industries. WIDE AREA NETWORK (WAN)
Wide Area Networks (WANs) connect larger geographic areas, such as London, the UK, or the world. In this type of network dedicated transoceanic cabling or satellite uplinks may be used.
ADVANTAGES OF NETWORK
• Speed. Sharing and transferring files within Networks are very rapid. Thus saving time, while maintaining the integrity of the file.
• Cost. Individually licensed copies of many popular software programs can be costly. Networkable versions are available at considerable savings. Shared programs, on a network allows for easier upgrading of the program on one single file server, instead of upgrading individual workstations.
• Security. Sensitive files and programs on a network are passwords protected (established for specific directories to restrict access to authorized users) or designated as "copy
Once one of the computers is properly configured as a file server, users can access the storage by mapping the drives on the respective computers. The file server will be mapped as a drive and users can store, edit and access files directly from the shared storage disk. The disk will be connected to each computer. For example, when a user needs to access any file from the file server, he/she can access the drive that will now be mapped on the every computer (Science - Opposing Views, 2014).
1)A network is when two or more computers are connected together and are able to share data and communication.
This allows you to share centrally stored files to all of your connected computers easily. It also makes sharing a printer much easier than transfering everything to one computer as a gateway.
i) Disk : file server, virtual disk server, feature on interest server and so on
Files are stored at server disk. Clients do read and write operations on the network.
It is generally limited to a geographic area such as a writing lab, school, or building. Rarely are LAN computers more than a mile apart. In a typical LAN configuration, one computer is designated as the file server. It stores all of the software that controls the network, as well as the software that can be shared by the computers attached to the network. Computers connected to the file server are called workstations. The workstations can be less powerful than the file server, and they may have additional software on their hard drives. On many LANs, cables are used to connect the network interface cards in each computer; other LANs may be wireless.
I would define a network as a group of computers that are connected together with physical cables or wireless capabilities along with a series of peripheral devices such as, routers, switches, servers or printers etc…for sharing data, software and other resources between different users. When talking about bandwidth, it is a range of frequencies or wavelengths in which data is transmitted. With digital devices, bandwidth is calculated by bits per second or bytes per second and with analog devices, by cycles per second, or hertz.
Server: The server acts as the main computer. It had high end hardware just like the workstations, but
The first topology represented is the Ring topology. A ring topology is a network in which all traffic moves in only one direction because of this the speed is faster than some other topologies, even as network traffic increases. Due to the configuration of a ring topology the resources of the network are available to every device and the cost of setup can be lower than some of the more complicated topologies. However, the configuration of the Ring topology is also a disadvantage. Since a file sent to any device within the network has to pass through every device, if one device fails the entire network goes down. (Ethernetpedia)
Computer Network: A LAN (local area network) that connects computers in a house, at school or at work.
Client Server is a computer system where a central server provides data of networked workstations.

A network is the way to communicating throughout the internet; also, it is connected to the group of computers that allow to sharing the information through a network. Not only that network is just for sharing the information though connected of group computers, but for internet that including social media, game online, telecommunication, programming that would be require network for professional career, and more that can be any in the real world, even that can be also for security throughout network to protect whoever uses network for personal and business. A network is a-must
Network Operating systems: A Network operating system is the software, which runs on the server. It allows the server to control functions within a network. This could include users, groups and security. Some examples of these operating systems are Windows, Linux and Mac OS.
This is one of the crucial advantages of networking computers. Everyibe can find and share data because of networking. This is beneficial for large organizations to maintain their information in an
