Topology Tree

9:06 AM Computer Networking 25 comments

Tree topology is the topology of computer networks is shaped like a tree. In the tree topology all the computers do not have the same position. Computers that higher position control computer underneath it, so the computer network is dependent on computers that higher position. For the same computer kedudukanya called peer topology. See the picture below Tree Topology...

Topology STAR

9:59 PM Computer Networking 4 comments

Star topology is the topology of the most popular. Star topology is a network topology of the most frequently used. Such topology is usually in apikasikan in schools, office buildings, or university. In a star topology, centralized control and all links must pass through the center of the channel data to all nodes or a computer of his choice. Central node is called the primary station or server and the other part is called the secondary station or client. In the star topology, which disrupted the...

Topology RING

12:32 AM Computer Networking 5 comments

Ring topology is the topology of computer networks that is shaped like a ring, all computers connected to each other and uninterrupted. The drawback of this topology is that every node in the network will always come and manage the information passed in the network, so if there is a disturbance in a node then the entire network will be disrupted. The advantages of Ring topology is not collision or collisions such as data transmission on the bus topology, since only one node can transmit...

Topology BUS

10:52 PM Computer Networking 1 comment

BUS topology is old technology, connected by a cable in a line topology of computer networks that use coaxial cable and use a BNC connector. At each end of the BUS topology there is a 50 Ohm terminator as an end connections. BUS topology advantages include the installation and pemeliharaanya cheap. BUS topology weakness that is less reliable, if one network is broken then all tissues will die. Topology BUS...

5:33 PM Computer Networking 3 comments

Computer network topology is the architecture of a computer network or a picture of the relationship between the planning of dams computer Local Area Network LAN or Wide Area Network WAN. There are several types of computer network topologies are used. 1. BUS topology 2. RING topology 3. STAR topology 4. TREE topology 5. MESH topology 6. HYBRID topol...

Router

5:22 PM Computer Networking 8 comments

The router is a computer networking device that is capable of transmitting data or information from one network to another are different. The router will find the best path to send a message based on the destination address and source address. This process is called routing. Each router knows its local network addresses. The router's capabilities include the following. 1. The router can translate information between LAN Local Area Network and Internet 2. The router will find an alternative path...

Bridge Computer Network

12:45 PM Computer Networking 1 comment

Bridge functions the same as the repeater function in a computer network but the bridge is more intelligent than repeaters. Bridge works at OSI layer 2. Bridge can connect a computer network having a different transmission. For example bridges can connect computers using Ethernet Baseband networks and computer networks that use Ethernet Broadband.Bridge is...

Repeater

12:15 PM Computer Networking 2 comments

Repeater is a device that works at layer 2. Repeater is a device used to amplify signals in a computer network. Repeater will receive signals from a Local Area Network LAN segmentand then transmit back to the same signal strength. In this way the network LAN Local AreaNetwork can be a lot. The use of repeaters between two or more segments require...

Switch

3:39 PM Computer Networking No comments

Switch is a concentrator that has a better traffic management in comparison with the hub.Switches are network devices that work layer of data-link, similar to a bridge, or often referred to as a multiport bridge function to connect multiple LAN segments within a larger network. Compare also with the hub. Switches have the ability to determine the destination MAC address of the packet. Rather than passing the packet to all ports, switches forward it to the port where he addressed.Thus,...

HUB

11:45 AM Computer Networking No comments

The hub is a concentrator on a computer network. Which serves to unite the network cablesfrom each workstation, server, or other device. different hubs with switches. Hub with connections in one direction, meaning that if the computer has to take turns if you want tocommunicate with each other, like a walkie talkie. HUB Symbol HU...

Ethernet Card / Network Interface Card

11:48 PM Computer Networking No comments

Ethernet Card is a card that is used for the interconnection network between computerswith the other network devices. How it works ethernet cards based on a broadcast network,every node in a network receives every transmission of data sent by a node to another.every ethernet card has a 42 bit address at all familiar with...

Cable

11:35 PM Computer Networking No comments

There are several types of cables used and the standard data communication in computer networks. These cables must be tested before eligibility before marketed and in use. Keep in mind that nearly 85% of failures in the computer network because of an error inthe communication media used, including cables and connectors as well as kiualitaspemasanganya. Types of cables used in computer...

Computer Network Hardware

5:30 PM Computer Networking No comments

In establishing the network is both a Local Area Network (LAN) and Wide Area Network (WAN), we need a media hardware and software. some media hardware needed to build a computer network. 1. Cable 2. Ethernet Card 3. Hub 4. Switch 5. Repeater 6. Bridge 7. Rou...

WAN (Wide Area Network)

5:17 PM Computer Networking No comments

This type of computer network is a network that already uses wirelless transmission,satellite, or fiber optic cable, as network coverage is broader than Local Area Network (LAN) Wide Area Network (WAN) and Metropolitan Area Network MAN. Notonly covering one city or inter-regional inter-state but is now reaching even the world. WAN is usually more...

Metropolitan Area Network (MAN)

4:37 PM Computer Networking No comments

This type of computer network has a larger scale than the network computer Local Area Network. Computer Network Metropolitan Area Network (MAN) usually covers the entirecity, province or state. for example, a network of several corporate offices within a large citywhich is connected to a computer network with each other. Metropolitan Area Network...

Local Area Network (LAN)

3:55 PM Computer Networking No comments

Local Area Network (LAN) is a computer network is the smallest. Computer network that isrestricted to relatively small areas. Generally limited by the environmental area, such as schools, offices, or buildings. The distance between nodes on a Local Area Network (LAN) the maximum is 100 m. Local Area Network (L...

Types of computer networks

3:42 PM Computer Networking No comments

The types of computer networks In general, a computer network is divided into 3 types: 1. Local Area Network (LAN) 2. Metropolitan Area Network (MAN) 3. Wide Area Network (W...
