Introduction to Network Types

LAN, WAN and Other Area Networks


One way to categorize the different types of computer network designs is by their scope or scale. For historical reasons, the networking industry refers to nearly every type of design as some kind of area network. Common examples of area network types are:
  • LAN - Local Area Network
  • WLAN - Wireless Local Area Network
  • WAN - Wide Area Network
  • MAN - Metropolitan Area Network
  • SAN - Storage Area Network, System Area Network, Server Area Network, or sometimes Small Area Network
  • CAN - Campus Area Network, Controller Area Network, or sometimes Cluster Area Network
  • PAN - Personal Area Network
  • DAN - Desk Area Network
LAN and WAN were the original categories of area networks, while the others have gradually emerged over many years of technology evolution.
Note that these network types are a separate concept from network topologies such as bus, ring and star.

LAN - Local Area Network

A LAN connects network devices over a relatively short distance. A networked office building, school, or home usually contains a single LAN, though sometimes one building will contain a few small LANs (perhaps one per room), and occasionally a LAN will span a group of nearby buildings. In TCP/IP networking, a LAN is often but not always implemented as a single IP subnet.
In addition to operating in a limited space, LANs are also typically owned, controlled, and managed by a single person or organization. They also tend to use certain connectivity technologies, primarily Ethernet and Token Ring.

WAN - Wide Area Network

As the term implies, a WAN spans a large physical distance. The Internet is the largest WAN, spanning the Earth.
A WAN is a geographically-dispersed collection of LANs. A network device called a router connects LANs to a WAN. In IP networking, the router maintains both a LAN address and a WAN address.
A WAN differs from a LAN in several important ways. Most WANs (like the Internet) are not owned by any one organization but rather exist under collective or distributed ownership and management. WANs tend to use technology like ATM, Frame Relay and X.25 for connectivity over the longer distances.

LAN, WAN and Home Networking

Residences typically employ one LAN and connect to the Internet WAN via an Internet Service Provider (ISP) using a broadband modem. The ISP provides a WAN IP address to the modem, and all of the computers on the home network use LAN (so-called private) IP addresses. All computers on the home LAN can communicate directly with each other but must go through a central gateway, typically a broadband router, to reach the ISP.

Other Types of Area Networks

While LAN and WAN are by far the most popular network types mentioned, you may also commonly see references to these others:
  • Wireless Local Area Network - a LAN based on WiFi wireless network technology
  • Metropolitan Area Network - a network spanning a physical area larger than a LAN but smaller than a WAN, such as a city. A MAN is typically owned an operated by a single entity such as a government body or large corporation.
  • Campus Area Network - a network spanning multiple LANs but smaller than a MAN, such as on a university or local business campus.
  • Storage Area Network - connects servers to data storage devices through a technology like Fibre Channel.
  • System Area Network - links high-performance computers with high-speed connections in a cluster configuration. Also known as Cluster Area Network.

What is a Network topology

A topology – is the characteristic of a communication network that is concern both with the physical configuration of the cabling that is used to inter connect communicating system and the logical way in which system view the structure of the network. Topology is the therefore physical or logical arrangement of computers
Factors to consider when selecting a topology
  1. Cost – whatever transmission medium is chosen for a Local Area Network has to be physically installed in the building, this maybe a lengthy process including the installation cables and raceways. For a Network to be cost effective one would strive to minimize installation cost. This may be achieved by using the proper hardware linking the cables, good modems, cost effective computers to reduced cost
  2. Flexibility – one of the main benefit of a local Area Network is it ability to have the data processing and peripheral nodes distributed around a given area. This means that the computing power and equipment can be located close to the ultimate users. Because the arrangements of furniture, internal walls etc in the offices is often subject to change. The topology should allow for easy reconstruction of the network which involves moving existing nodes and adding new nodes
  3. Reliability – The topology chosen for the network can help by allowing the location of the fault to be detected and to provide some means of isolating the faults
 

Types of Network Topologies

Network star topology also known as Radial topology
This topology consist of a central nodes to which all other nodes are connected, star topology is used in most existing information network involving data processing and voice communication. In many cases when a building is wired with a star topology, faced cables radiate out from the centre to intermediate connection point to wiring cables. This allows sufficient connection point to be provided for one sub – area, while providing flexibility in their allocation within that area
star topology
 
Advantages of star topology
  • Diagnostic and isolation of problem is easy
  • Easy to add a new computer system to the network
  • Failure of one workstation does not affect the entire network
  • Uses a single access protocols
  • Provide ease of service
  • Is very fast
Disadvantages of star topology
  • There is central node dependency
  • Becomes expensive when purchasing the nodes
  • Always requires very long cable length when connecting many nodes
 

Bus Topology also known as Linear Topology

bus topology
 
It is the simplest method of networking computers. It consists of a single cable known as a trunk, backbone or segment that connects all the computers in the network. Each system is directly attached to a common communication channel. Signal that is transmitted over the channel makes up the messages.  As each message passes along the channel each system receives it, after receiving the message each system examine the destination address contained in the message, if the destination address tells a particular system that the message is addressed to it, that system accepts and process the message, if the message address tells the computer that the message is intended for another system, that computer will ignore the message
On a bus topology signals are send to all the computers in the network to keep the signal from bouncing back and forth along the cable a terminator (British Naval Connector) is placed at the end of the cable. In a bus topology only one computer can send data at a time, therefore the more computers in a bus the slower data transmission in the network
Advantages of Bus topology
  • Cheap because of its simplicity
  • Requires a short cable length
  • Easy to expand the network
  • Simple to setup compared to Star and Ring topology
  • There is no chances of data collision since one computer transmit at a time
  • Locating cable fault in a bus topology is relatively easy
  • Bus topology is ideal for one to many data transmission
  • Signal on the cable are bidirectional hence reaches all the nodes
Disadvantages of Bus topology
·         Fault diagnosis is difficult in a bus topology – detection of fault may have to be performed from any point in the network
·         Fault isolation is difficult – if fault in the node is detected  the node can simply be removed but if the fault is in network medium itself and entire segment of the Bus must be disconnected to isolate the fault
·         Repeater configuration – When a Bus type  network has its backbone intended for using a repeater, configuration maybe necessary thus may involve tailoring cable length, adjusting terminator etc
·         Computer nodes must be intelligence – each node on the network is directly connected to the central Bus. This means that each node must have method of deciding and detecting its own data
   Ring Topology

Computer Software Definition

Software is a generic term for organized collections of computer data and instructions, often broken into two major categories: system software that provides the basic non-task-specific functions of the computer, and application software which is used by users to accomplish specific tasks.
System software is responsible for controlling, integrating, and managing the individual hardware components of a computer system so that other software and the users of the system see it as a functional unit without having to be concerned with the low-level details such as transferring data from memory to disk, or rendering text onto a display. Generally, system software consists of an operating system and some fundamental utilities such as disk formatters, file managers, display managers, text editors, user authentication (login) and management tools, and networking and device control software.
Application software, on the other hand, is used to accomplish specific tasks other than just running the computer system. Application software may consist of a single program, such as an image viewer; a small collection of programs (often called a software package) that work closely together to accomplish a task, such as a spreadsheet or text processing system; a larger collection (often called a software suite) of related but independent programs and packages that have a common user interface or shared data format, such as Microsoft Office, which consists of closely integrated word processor, spreadsheet, database, etc.; or a software system, such as a database management system, which is a collection of fundamental programs that may provide some service to a variety of other independent applications.
Software is created with programming languages and related utilities, which may come in several of the above forms: single programs like script interpreters, packages containing a compiler, linker, and other tools; and large suites (often called Integrated Development Environments) that include editors, debuggers, and other tools for multiple languages.


Computer Hardware Definition

Hardware is a comprehensive term for all of the physical parts of a computer, as distinguished from the data it contains or operates on, and the software that provides instructions for the hardware to acoomplish tasks. The boundary between hardware and software is slightly blurry - firmware is software that is "built-in" to the hardware, but such firmware is usually the province of computer programmers and computer engineers in any case and not an issue that computer users need to concern themselves with.
A typical computer (Personal Computer, PC) contains in a desktop or tower case the following parts:
  • Motherboard which holds the CPU, main memory and other parts, and has slots for expansion cards
  • power supply - a case that holds a transformer, voltage control and fan
  • storage controllers, of IDE, SCSI or other type, that control hard disk , floppy disk, CD-ROM and other drives; the controllers sit directly on the motherboard (on-board) or on expansion cards
  • graphics controller that produces the output for the monitor
  • the hard disk, floppy disk and other drives for mass storage
  • interface controllers (parallel, serial, USB, Firewire) to connect the computer to external peripheral devices such as printers or scanners

Internet

This is the world-wide network of computers accessible to anyone who knows their Internet Protocol (IP) address - the IP address is a unique set of numbers (such as 209.33.27.100) that defines the computer's location. Most will have accessed a computer using a name such as http://www.hcidata.com/. Before this named computer can be accessed, the name needs to be resolved (translated) into an IP address. To do this your browser (for example Netscape or Internet Explorer) will access a Domain Name Server (DNS) computer to lookup the name and return an IP address - or issue an error message to indicate that the name was not found. Once your browser has the IP address it can access the remote computer. The actual server (the computer that serves up the web pages) does not reside behind a firewall - if it did, it would be an Extranet. It may implement security at a directory level so that access is via a username and password, but otherwise all the information is accessible. To see typical security have a look at a sample secure directory - the username is Dr and the password is Who (both username and password are case sensitive).


Intranet

This is a network that is not available to the world outside of the Intranet. If the Intranet network is connected to the Internet, the Intranet will reside behind a firewall and, if it allows access from the Internet, will be an Extranet. The firewall helps to control access between the Intranet and Internet to permit access to the Intranet only to people who are members of the same company or organisation.

In its simplest form, an Intranet can be set up on a networked PC without any PC on the network having access via the Intranet network to the Internet.

For example, consider an office with a few PCs and a few printers all networked together. The network would not be connected to the outside world. On one of the drives of one of the PCs there would be a directory of web pages that comprise the Intranet. Other PCs on the network could access this Intranet by pointing their browser (Netscape or Internet Explorer) to this directory - for example
U:\inet\index.htm.
From then onwards they would navigate around the Intranet in the same way as they would get around the Internet.

Extranet

An Extranet is actually an Intranet that is partially accessible to authorised outsiders. The actual server (the computer that serves up the web pages) will reside behind a firewall. The firewall helps to control access between the Intranet and Internet permitting access to the Intranet only to people who are suitably authorised. The level of access can be set to different levels for individuals or groups of outside users. The access can be based on a username and password or an IP address (a unique set of numbers such as 209.33.27.100 that defines the computer that the user is on).
