Local Network Topology LAN (Local Area Network Topology)
Local Network (LAN) for Purposes of Information And Communication With computer networks, each job is expected to be completed quickly. Computer network capable of connecting computers to other computers. One of the computer network is the Internet. The Internet is the network technology giant that has become a reality in information and communication needs of millions of people in this world. In its first development, computer networks are still using coaxial cable. Now, the network was built with the cable of optical fiber (Fiber Optics) or wireless communication (wireless) TCP / IP (Transmission Control Protocol / Internet Protocol) is a group of protocols that manage computer data communications on the Internet. The computers that connect to the internet to communicate with TCP / IP, because it uses the same language differences in types of computers and operating systems is not a problem. Computer PC with Windows operating systems can communicate with Macintosh computers or with a Sun SPARC running Solaris. So, if a computer using TCP / IP and is connected directly to the internet, then the computer can be connected with computer anywhere in the world that is also connected to the internet.
The characteristics of computer networks:
1. share hardware (hardware).
2. sharing software (software).
3. sharing of communication channels (internet).
4. sharing data with ease.
5. facilitate communication between network users.
Computer Networking
Computer network is a set of computers connected together and can share resources, such as printers, CDROMs, exchange files, and electronic communications between computers. The relationship between computers in a network can use the media cable, telephone, radio, satellite or infrared light (infrared).
Type of computer networks are divided into two classifications, based on technology and distance-based trasmisi.
A. Types of Computer Network Based Transmission Technology.
The type of network based transmission technology is divided into two, namely broadcast networks and point-to-point.
Here's the description:
1. Broadcast Network This network uses a single communication channel that is used all the computers or machines that connect to this network together.
2. Network Point-to-Point Network consists of several computers or machines which often have a much different route because of its distance. In the send packets from a source machine to a destination, the packets of this type must be through the intermediary machine that can be through many routes.
In general, local network or networks that are geographically small tend to use broadcast networks, while larger networks can use the Network Point-to-Point.
B. Types of Computer Network Based on Distance.
Type of distance-based network is divided into three, namely the Local Area Network (LAN), Metropolitan Area Network (MAN) and Wide Area Network (WAN).
Here's the description:
1. Local Area Network (LAN)
Local Area Network (LAN) is the number of computers linked together in one particular area that is not so broad, as in one office or building. Broadly speaking there are two types of network or LAN, the network Peer to Peer and Client-Server networks. In peer to peer network, every computer connected to the network can act both as workstations and servers. While on the network Client-Server, only one computer that acts as a server and other computers acting as workstations. Between these two types of networks each have advantages and disadvantages, in which each will be explained.
LAN is composed of several basic elements that include hardware and software components, namely:
* Physical Components of Personal Computer (PC), Network Interface Card (NIC), cable, network topology.
* Components of the Network Operating System Software, Network Adapter Drivers, Network Protocols.
This is known as area networks, namely network limited to a small area, such as the office environment in a building, school, or college. In a LAN network, there is one computer called a server, whose function is to provide software services (software), managing network activity and save the file. In addition there are servers connected to another computer in the network (network) is called the workstation (client). In general LAN technology using the media untruk cable connects computers that are used.
LAN can be distinguished by three characteristics, namely size, transmission technology, and topology. Transmission technology that can be used is a single-cable transmission. In normal LAN, the transmission speed of around 10 - 100 Mbps (megabits / second), and a small error factor. Topology used is usually the bus topology, Star and Ring.
2. Metropolitan Area Network (MAN)
This network is more extensive than the LAN network and reach among regions within provinces. MAN network linking smaller networks, such as the LAN environment that leads to a larger area. For example, some banks that have a network of computers in each branch can relate to each other so that customers can conduct transactions at branches and in the same province.
3. Wide Area Network (WAN)
This network covers a large area and is able to reach the provincial boundaries of existing states and even other dibelahan earth. WAN network to connect one computer to another computer by using a satellite or undersea cable. Topology is used WAN topology erratic in accordance with what would be used. Network Topology (Form Network) Network Topology is the physical description of the pattern of relationships between network components, including servers, workstations, hubs / switches and cables

general network topology
There are three kinds of commonly used network topology, the Bus, Star and Ring. Network Topology Topology is a pattern of relationship between the terminal in a computer network. This pattern is closely associated with the method of access and delivery medium used. Topology that is highly dependent on geographical location of each terminal, the quality control needed in the communication or messaging, as well as the speed of data transmission.
a. Point to Point (Point to Point).
Point to point network is the simplest network but can be used widely. Once the network is simply this, that often are not considered as a network but only an ordinary communication. In this case, both nodes have the same level position, so that any node can initiate and control the relationship in the network. Data directly sent from one node another conclusion as the recipient, for example between the terminals with the CPU.

b. Star Network (the Network Stars).
In a star configuration, some existing equipment will be connected into a central computer. Existing controls will be concentrated at one point, such as manage the workload and arrangement of existing resources. All links must be related to the center if you want to distribute any other conclusion that the intended data. In this case, when the center was down, then all the terminals will also be disrupted. Star network model is relatively simple, so widely used by the per-bank-right which usually has many branches that spread dipelbagai location. With the configuration of these stars, then all sorts of activities that exist in the branch offices it can be controlled and coordinated well. In addition, education also took great advantage of this star network in order to control the activities of their pupils.
c. Ring Networks (Network Ring)
In this network there are several devices interconnected with each other and will eventually form the chart as well as a ring. Ring network does not have a point that acts as a central regulator or data traffic, all nodes have the same level. The data sent will go through several nodes, so arrive at the destination node. In presenting the data, the network can move in one or two directions. However, existing data to keep moving in one direction at a time. First, the message that there will be delivered from point to another in one direction. When encountered a failure, for example there is damage to existing equipment, existing data will be sent by way of a second, that message and then transmitted in the opposite direction, and could eventually end up at destination. Such configuration is relatively more expensive when compared with the star network configuration. This is due, every node that is going to act as a computer that will overcome every application that it faces, and must be able to share resources on the existing network. In addition, this system is more suitable for use in systems that are not centralized (decentralized-system), which is not necessary to have a certain priority.
d. Tree Network (Network Tree)
In tree networks, there are several levels of nodes (node). Central or higher level node, another node can set a lower level. Data sent to the central node first. For example to move from computer to computer node to node-3-7 as well as in the figure, the data must pass through node-3, 5 and node-6 before ending in node-7. Keungguluan network tree model like this is, to the formation of a group that is required at all times. For example, companies can form a group consisting of terminal accounts, as well as on other groups formed to terminal sales. The drawback is, if the node is higher then does not work, then another group who are below it eventually also became ineffective. The workings of this tree network is relatively slow.
e. Bus Network Configuration
known as the bus-network, which is suitable for areas that are not too broad. Each computer (each node) will be connected by a communication cable through an interface. Each computer can communicate directly with computers or other equipment contained within the network, in other words, every node has an equal footing. In this case, the network is not dependent on the existing computer center, so that when one device or one node is destroyed, the system can still operate. Each node which is having its own address or natural. So for access to data from one node, the user or the user simply mentioning the address of the node in question.

f. Plex Network (Network Combination)
Is the network truly interactive, where each node has the ability to directly access not only to computers, but also with equipment or other knot. In general, this network has a shape similar to a star network. Organization of existing data using the de-centralization, is to perform maintenance, use centralized facility
