Name: Rataa Jariyasakdipong Room: M.2/6 No.6 Vocabulary: Network Terms LAN Local Area Network : Multiple personal computers connected on a network MAN Metropolitan-Area Network : MAN is a network that is utilized across multiple buildings. A MAN is much larger than the standard Local-Area Network (LAN) but is not as large as a Wide Area Network (WAN) and commonly is used in school campuses and large companies with multiple buildings. WAN . Wide Area Network : A network that extends over a long distance. Each network site is a node on the network. CAN Campus Area Network : The modern education system, one way or another, aims to form students' abilities to work with information. It is no coincidence that the prior areas of education development pay special attention to form skills of information processing, which later becomes the mainstay of professional activity of graduates in the information society, a necessary component of information culture. In such circumstances, students will acquire the necessary knowledge to express themselves creatively, learn to evaluate the accuracy of the information, develop critical thinking, and distinguish information and knowledge. PAN Personal Area Network : PAN, is a localnetwork designed to transmit data between personal computing devices (PCs), personal digital assistants (PDAs) and telephones. Gaming devices, like a game console system, may also be set up on a PAN. PROTOCOL A set of rules for the exchange of data between a terminal and a computer or between two computers. FIREWALL Software or hardware that guards against unauthorized access into an internal network; keeps internal network secure while allowing communication with the rest of the internet. BANDWIDTH When referring to a data connection,bandwidth, communication speed, orconnection speed is the total maximum transfer rate of a network cable or device. Essentially, it is a measurement of how fast data can be sent over a wired or wireless connection, usually measure in bits per second. GATEWAY When referring to a network, a gateway is an address used as an entry point into another network. For example, 166.70.10.1 could be used as a gateway. It is common for an IP address ending with .1 and .2 to be a network's gateway. The gateway is commonly the address of a network device such as a network router. NETWORK TOPOLOGY Network Topology is the schematic description of a network arrangement, connecting various nodes(sender and receiver) through lines of connection. BUS TOPOLOGY. Alternatively referred to as a line topology, a bus topology is a network setup in which each computer and network device are connected to a single cable orbackbone. The following sections contain both the advantages and disadvantages of using a bus topology with your devices. RING TOPOLOGY ring topologyis a computer network configuration where the devices are connected to each other in a circular shape. Each packet is sent around the ring until it reaches its final destination. Ring topologies are used in both local area network (LAN) and wide area network (WAN) setups. The picture to the right is a visual example of a network using the ring topology to connect several computers together. MESH TOPOLOGY A network setup where each computer and network device is interconnected with one another, allowing for most transmissions to be distributed, even if one of the connections go down. This topology is not commonly used for most computer networks as it is difficult and expensive to have redundant connection to every computer. However, this topology is commonly used for wireless networks. Below is a visual example of a simple computer setup on a network using a mesh topology. TREE TOPOLOGY Tree Topology integrates the characteristics of Star and Bus Topology. Earlier we saw how in Physical Star network Topology, computers (nodes) are connected by each other through central hub. And we also saw in Bus Topology, work station devices are connected by the common cable called Bus. After understanding these two network configurations, we can understand tree topology better. In Tree Topology, the number of Star networks are connected using Bus. This main cable seems like a main stem of a tree, and other star networks as the branches. It is also called Expanded Star Topology. Ethernet protocol is commonly used in this type of topology. The diagram below will make it clear. STAR TOPOLOGY star topology is one of the most common network setups. In this configuration, everynode connects to a central network device, like a hub, switch, or computer. The central network device acts as a server and the peripheral devices act as clients. SERVER For a local-area network, a hierarchical model in which one or more computers act as dedicated servers and all the remaining computers act as clients. The server fills requests from clients for data and other resources. ISP Internet Service Provider : ISP is a company that provides Internet access to users or subscribers of its service. An ISP gives you an Internet account (access to the Internet), e-mail address, web space for a web page for around $20.00 U.S. dollars a month. Prices may vary in other countries.

ETHERNET Originally known as Alto Aloha Network,Ethernet is a widely used local-area network (LAN)protocol originally created by Xerox PARC in 1973by Robert Metcalfe and others (U.S. Patent # 4,063,220). Being the first network to provide Carrier Sense Multiple Access / Collision Detection (CSMA/CD), Ethernet is a fast and reliable network solution that is still widely used today. Below is a listing of different standards of Ethernet and additional information about each of them. NETWORK A network is a collection of computers, servers, mainframes, network devices, peripherals, or other devices connected to one another allowing for data to be shared and used. A great example of a network is the Internet, connecting millions of people all over the world together. Below is an example image of what a home network with multiple computers and other network devices all connected to each other and the Internet.
