Computer Networks
Today's computer networks are very important because they are part of human needs, and computer networks help us to work and communicate with each other even though they are widespread. Without a computer network, we will not be able to access the Internet, so a computer network is very important for today's life. For more details, let's consider the review below.
Understanding computer networks, according to experts
1. Jaafar Noor Yudianto (2007)
According to Ja`far Nur Yudiyanto, a computer network is a system consisting of computers designed to be able to share resources (printers, CPUs), communication (e-mail, instant messages), and access to information (web browser).
2. Umi Proboyekti
According to Umi Proboyekti stated that a computer network is a large group of computers that are divided and interconnected in carrying out their duties. For example, it can be said that two computers are connected if they can exchange information.
3. Anonymous
According to Anonymous, computer networks are known as separate computer groups that are bound together using communication protocols through communication media so that you can share data, information and programs and use them with devices such as printers, hard disks, etc. In addition, a computer network can also be interpreted as a group of a number of communication terminals located in different locations consisting of more than one interconnected computer.
4. Abdul Qadir (2003)
According to Abdul Qadir (2003), a computer network is a relationship between two nodes (generally in the form of computers) or more whose main purpose is to exchange data.
5.Tananbaum (2002)
According to Tanaenbaum Computer Network is a set of hardware and software in a system that has certain rules to regulate all its members in conducting communication activities. Computers that are connected to the network become one node on the network. Whereas the host is generally defined as a computer connected to a network that can provide network services (network service).
6. Eyas Al-Saeed
According to Isas Al Saeed, a computer network is a system where many computers are connected to each other, so you can share the information and resources you have.
7. Madcoms
According to Madcoms, a computer network is a collection of many computers and other supporting equipment, which are connected in one unit and connected to each other.
8. Techi Wire House
According to Techi Wira House states that a computer network is a group of two or more computers connected to each other, with certain connections
9. Kristanto (2003)
According to Kristanto (in Tiranda, 2014) states that a computer network is a group of independent computers connected to each other, using communication protocols so that all computers connected to each other can share information, programs and resources and can also use each other devices other together, namely Hard drive printers, etc.
9. Wikipedia
According to Wikipedia, Indonesia determines that a computer network is a system consisting of several computers (more than one computer) designed to be able to share resources and communicate with each other and also be able to access information with each other.
10. Zymon Machajewski
According to Zymon Machajewski he stated that computer networks are computers that are connected to each other that are intended to share or share alias resources. Internet resources are one of the most widely used and widely used resources in computer networks today.
1. Ring Topology
Ring topology is one type of ancient topology, but it is quite effective to handle the creation of local networks from a small number of computers. Ring topology will allow a packet of data or information to be accessed by client computers in a particular ring cycle. So, a new information can be accessed by client number 4, after being accessed by client numbers 1, 2, and 3 first.
2. Bus Topology
Bus topology is a type of topology that is quite cheap, because it only uses a kebel and also a connector to build a local network. The bus topology uses connectors and terminators to make a local network work.
3. Star Topology
Star topology is a type of topology that is widely used, on local networks. Star topology allows one server to serve more than two client computers simultaneously, with the help of network hardware, such as switches and hubs.
4. Tree Topology
Tree topology allows several small local networks in one building to be combined so that it becomes a single large local network. In addition to the tree topology it can also be possible to connect computers on a network with different levels or hierarchies. Suitable for use of LAN networks in high rise buildings.
5. Mesh Topology
Mesh topology is a type of local network topology that allows each computer to feedback to each other. Not suitable for use on large LAN networks, because it will complicate supervision.
Local area network, abbreviated as LAN, is a network that has a location of only about 100 meters. This one network is often used within a company, because the company uses a LAN network where within a company that uses a LAN network to take advantage of facilities to share confidential company data.
2. MAN (Metropolitan Area Network)
Metropolitan Area Network, abbreviated as MAN, is bigger than LAN network, which is a maximum of 10 s.d. 50 kilometers. This MAN network is used by a company that has branches in just one city.
3. WAN (Wide Area Network)
WAN abbreviated Wide Area Network is a computer network that has coverage between continents, by crossing a geographical boundary of the country and public property. WAN is usually used to connect two or more local networks so that users can communicate with other users even in different locations.
4. Internet (Interconnected Network)
Interconnected Network, abbreviated as the Internet, is a computer network that has a very broad reach to all regions of the earth. The internet is often used to share information globally that includes education, entertainment, technology, and others.
5. Wireless
Wireless Network this one is the simplest because it does not use cable. Which in its operation only relies on a radio technology (frequency). What is often also called a WLAN network (Wireless Local Area Network) or we often use Wi-Fi.
Understanding computer networks
A computer network is a communication network that allows computers to exchange data. The purpose of computer networks is to be able to achieve its goals, by each network komupter can provide and request services (services). The party who receives / requests the service is called a client and the person providing the service is called a server. The design is called a client-server system, and is used in almost all computer network applications.Understanding computer networks, according to experts

Computer Network Topology
Computer network topology is the design of a computer network, which determines how data packets and also information are transmitted between computers in the network. For creating a local network (LAN), there are several topologies that can be implemented, which are as follows:1. Ring Topology
Ring topology is one type of ancient topology, but it is quite effective to handle the creation of local networks from a small number of computers. Ring topology will allow a packet of data or information to be accessed by client computers in a particular ring cycle. So, a new information can be accessed by client number 4, after being accessed by client numbers 1, 2, and 3 first.
