What is Network?
• A network consists of two or more computers
that are linked in order to share resources (such
as printers and CDs), exchange files, or allow
electronic communications.
• The computers on a network may be linked
through cables, telephone lines, radio waves,
satellites, or infrared light beams.

Different Types of Networks
• Depending upon the geographical area covered
by a network, it is classified as:
– Local Area Network (LAN)

– Metropolitan Area Network (MAN)
– Wide Area Network (WAN)

– Personal Area Network (PAN)

Local Area Network (LAN)
• A LAN is a network that is used for communicating among
computer devices, usually within an office building or home. • LAN’s enable the sharing of resources such as files or hardware devices that may be needed by multiple users
•
• Is limited in size, typically spanning a few hundred meters, and no more than a mile
• Is fast, with speeds from 10 Mbps to 10 Gbps

• Requires little wiring, typically a single cable connecting to each device
• Has lower cost compared to MAN’s or WAN’s

Local Area Network (LAN)
• LAN’s can be either wired or wireless. Twisted pair,
coax or fibre optic cable can be used in wired LAN’s.
• Every LAN uses a protocol – a set of rules that governs how packets are configured and transmitted.

• Nodes in a LAN are linked together with a certain
topology. These topologies include:
– Bus
– Ring
– Star

• LANs are capable of very high transmission rates (100s
Mb/s to G b/s).

Local Area Network (LAN)

Advantages of LAN
• Speed
• Cost
• Security
• E-mail

• Resource Sharing

Disadvantages of LAN
• Expensive To Install

• Requires Administrative Time

• File Server May Fail

• Cables May Break

Metropolitan Area Network (MAN)
• A metropolitan area network (MAN) is a large
computer network that usually spans a city or a
large campus.
• A...

    ...NETWORK TYPES Esteban Solorzano-Vivar Wilmington University WIS.200.B2N01.SP2013 March 13, 2013 Introduction In today’s world, computers have had a quite impressive evolution. Computers are not only needed to do homework, but they have also become essential tools for work, social life, and everyday tasks. With the help of technology, computers now allow us to share information (emails, documents, etc.), resources and software applications in just seconds. This sharing often occurs through a network, which has become a fundamental aspect of technology today. The purpose of this paper is to explain how computers are linked with each other and the type of technology needed to build a network. What is a network? A network is a set of various computers that have an interconnection in order to share hardware, software, data, and resources using a communication medium between them (ComputerNotes). A network connects computers by means of cabling systems, specialized software, and devices that manage data traffic. Types of Networks The four main types of networks are: Local Area Networks (LANs), Campus Area Networks (CANs), Metropolitan Area Networks (MANs), and Wide Area Networks (WANs). The use of each type of...

    ...Jason Laborin 1/22/15 NT1210 Strong Unit 2 Lab 2.3 Network Types and Topologies Exercise 2.3.2 PAN: Personal Area Network is a new type of network that describes two or more devices that are located on your person and normally connect to one another via Bluetooth. LAN: Local Area Network created by a group of devices in close proximity to one another and are normally located inside the same building or structure MAN: Metropolitan Area Network high speed private networks which are created by one or more dedicated point to point links between multiple locations WAN: Wide Area Network connects two or more LANs that can be located large distances from one another, even across the globe. Exercise 2.2.3 Network topologies are often defined as the logical organization of the interconnected devices. Exercise 2.3.4 It would take one messages to get from A to D, and it would take the same to send from D to A. and the added wouldn’t have no initial effect on the network. Exercise 2.3.5 From A to B it would take two message. The central hub would take two messages to get from A to B, when using the switch it would take one message from A to B. there would be very little effect when adding a node between C and D because it is connected to a central devices like A and B. Exercise 2.3.6 It would only take one instant...

  • Introduction to Network Types Essay

    ...INTRODUCTION TO NETWORK TYPES Research Paper #1 Prepared for Professor Jewett Prepared by Anissa Truitt COOP Semester: Spring 2007 The article basically describes the different types of networks. It states "nearly every type of design is referred to as an ¬area network". The main networks discussed are, LAN and WANs. According to the article, these were the original categories of area networks. LAN, which stands for Local Area Network, connects devices over a relatively short distance via a network. WAN, which stands for Wide Area Network, spans over a large physical distance; hence the word "wide". An example of a LAN can be found within a school, office building or even in a home. The main technologies used in this type of network are Ethernet, and Token Ring. Basically, an Ethernet cable connects each computer to the network via a hub tat is connected to the (ISP) Internet Service Provider, through the router of course. LAN is operated in limited space. Token Ring is the topology used within a LAN network. In a Token Ring, uses a ring topology whereby the data is sent from one machine to the next and so on around the ring until it ends up back where it started. It also uses a token passing protocol which means that a machine can only use the...

    ...TYPES OF COMPUTER NETWORKS: A computer networks is a communication system connecting two or more computers that work together to exchange information & share resources. A network may consist of microcomputers or it may integrate microcomputers or other devices with large computer. Networks can be controlled by all nodes co-ordinarily & supply all resource. These networks differ in geographical size. There are three important types of networks. 1. Local Area Network 2. Metropolitan Area Network 3. Wide Area Network 1. Local Area Network: A computer is connected to other computer with cables and other means & make communication possible between them is called network. The network, which connects one or more computers within a limited distance of one another perhaps within the same building or within the same office premises, is known as Local Area Network. This requires special software NetWare, LAN Cards (Ethernet Card), cables and connectors etc required for connecting computers included in it. Many organisations need multi-user environment, which allows sharing of data as well as expensive resources like printers and storage. Following figures shows the multi-user system, which includes LAN. A local Area Network is a system of...

  • Types of Networks Essay

    ... Types of Networks Title of Paper Networks are the connections between two devices. How they are interconnected changes the type of network, while the principle is the same as our communication. Networks are made to exchange information in the shortest path possible with the best replication of the original data. Local Area Networks (LAN), Wide Area Networks (WAN), Campus Area Networks (CAN), Metropolitan Area Networks (MAN) and Home Area Networks (HAN) are all varieties of how devices can be interconnected to each other over a variety of distances (Peter Norton / University of Phoenix,  2006). The smallest network consists of just two devices connected to each other through some medium either a wireless method like Bluetooth™ or a cabled connection with Category 5 twisted pair cable, known as CAT-5. This smallest setup is known as a Local Area Network, which is not connected to a global information system like the internet (Peter Norton / University of Phoenix,  2006). WANs are geographically separated systems that are on the same network, these systems connect over public utilities but can appear to each other as a logical neighbor by using a technology known as Virtual Local Area Network (VLAN) (CISCO, n.d.).  Not all WANs will contain a VLAN.

    ...computers are hacking and pirating in the networks is very easy and it can lead to information damage or robbery and also if one compute is affected by a virus it can spread to the other easily.  3. What technology allows computer networks without wires? Wireless networking allows computer networks without wires. 4. Describe the difference between a LAN and a WAN. LAN is local area network, it consists of a group of networked computers that all located in one building. But WLAN is wide area network, it is a group of networked computers located in a variety of locations in a large geographic area. So WLAN is a larger network system. 5. Name and describe two ways that computers communication with one another The first way is a client/server network. All computers connect to one server with switches. And the server is powerful computer, the user of one computer can send documents to another computer with the server. The second way is the peer-to-peer network. It doesn’t have a server, every individual node act as clients and servers, and they connect to each other with the switch. 6. Name the two main network topologies Bus topology and star topology 7.
