hello guys, well come to my blogger
for all my friends who want to visit my blogger, I thank you, because it really helped me, for all my friends who are looking for what is a fundamental network here I will explain a little about what is a fundamental network.
Fundamental Computer Networks
Network Definition
A network is a set of devices and nodes (hosts) that are connected to each other and can communicate with each other. The constituent components start from the client, server, hub, switch, router, and the media used to connect these devices.
In simple terms the network can be interpreted as a method used to connect between one another simultaneously with a particular purpose. In its application, the network can be used for a variety of things, such as exchanging information, exchanging data, conducting network conversations, television, and others.
Network Making Objectives
Exchange information between each other in available networks.
Search for information needed in one network.
Share or exchange data between each other in one network.
Backup data in the event of a disaster somewhere.
Network Distribution
Based on geography
1. Personal Area Network (PAN)
Personal Area Networks are often abbreviated as PAN, are computer networks based on geographical range used for communication with other computer equipment (for example printers, modems, handphones, PDAs, Bluetooth etc.).
2. Local Area Network (LAN)
Local Area Network, is a personal computer network that bisects areas in one room, a building or campus. The reach of a local area network (LAN) computer network is around 10 Km and the transmission media on this computer network is in the form of cable. But there are also those that do not use cables and are called wireless LANs. LANs are often used to connect personal computers and workstations in the office of a company or factory to use together resources (resources, eg printers) and exchange data.
3. Metropolitan Area Network (MAN)
Basically technology used in computer networks Metropolitan Area Networks (MAN) is almost the same as Local Area Networks (LAN). The difference is that the area coverage of the Metropolitan Area Network is greater than the Local Area Network, the range of metropolitan area networks ranges from 10-45 Km. Usually metropolitan area networks are used to connect offices, campuses or banks located in one city and different locations so that they can be used for private or public purposes. This network generally uses transmission media with microwaves or radio waves. But there are also those who use leased lines.
4. Wide Area Network (WAN)
Wan is a wide area network that is the internet that has a very wide network coverage that covers the whole world.
5. Internet
Actually there are many networks in the world, often using different hardware and software. People who are connected to the network often hope to be able to communicate with other people who are connected to other networks. This desire has resulted in the emergence of different and compatible networks. Usually to use this network a machine called a gateway is needed. Gateway is used to connect and carry out the necessary translations, both hardware and software. This connected set is called the internet.
Based on the Network Topology
1. Mesh Topology
Mesh topology or mesh topology is a form of relationship between devices where each device is connected directly to other devices in the network. As a result, in the mesh topology each device can communicate directly with the intended device (dedicated links).
2. Star Topology
Star topology or star topology is a form of network topology in the form of convergence from the middle node to each node or user. Star topology includes low-cost network topology.
3. Bus Topology
Bus topology is a topology that is widely used in the use of cable mushrooming. By using the T-Connector (with a 50ohm terminator at the end of the network), the computer or other network devices can easily be connected to each other.
4. Ring Topology
Ring topology or ring topology is a network topology in the form of a series of dots, each of which is connected to two other points, so as to form a circular path forming a ring. In the ring topology, data communication can be interrupted if one point experiences interference. The FDDI network anticipates this weakness by sending data clockwise and counter-clockwisethe same. Ring topology is used in networks that have high performance, networks that require bandwidth for time-sensitive features such as video and audio, or when performance is needed when a large number of computers are connected to the network. Tree Topology Tree topology or tree topology is a combination of characteristics between star topology and bus topology. This topology consists of a collection of star topologies that are connected in a bus topology as a backbone or backbone path. Computers are connected to the hub, while other hubs are connected as backbone paths. This networkology is also called a multilevel network topology. This topology is usually used for interconnection between central and different hierarchies. For the lower hierarchy it is depicted at a low location and the higher up has the higher hierarchy. This type of network topology is suitable for computer network systems.
6. Hybrid Topology Combining several topologies. One main cable connects each connection point (computer) that is connected to a connector called the T-Connector and at the end must end with a terminator. The connector used is BNC type (British Naval Connector), actually BNC is the name of the connector instead of the name of the cable, the cable used is RG 58 (Thinnet Cable). The installation of the busloaded bus topology is very simple and inexpensive but as many as it can only consist of 5-7 computers. Based on how it works: 1. Client-Server Network Client-Server Network is a computer network that connects between server computers and client computers directly. Or in other words the client computer is directly connected / connected to the server without any routing process.
2. Peer to Peer Network Peer to peer network is a network that connects similar devices such as computers to computers directly without any other media such as routers, switches, hubs or others. This network transmission usually uses crossover UTP cable or uses wireless. For example, an Ad Hoc network that is connected to wireless.
Now, my friend's post this time may be useful.
Wassalamu'alaikum Wr. Wb. and see you later
