You are not alone…
![Page 39: Chp 5 tech. revolutions and its effect on business](https://reader035.vdocuments.us/reader035/viewer/2022062617/54c0f2d84a7959873b8b45e3/html5/thumbnails/39.jpg)
Computer Networks• A computer network is a system for communicating
between two or more computers and associated devices. It is an interconnection of computers for the purposes of sharing information and resources.
• A popular example of a computer network is the internet, which allows millions of users to share information
• Computer networks can be classified according to their size:– Personal area network (PAN)
– Local area network (LAN)
– Metropolitan area network (MAN)
– Wide area network (WAN)
![Page 40: Chp 5 tech. revolutions and its effect on business](https://reader035.vdocuments.us/reader035/viewer/2022062617/54c0f2d84a7959873b8b45e3/html5/thumbnails/40.jpg)

Personal Area Network• A PAN is a network that is used for
communicating among computers and computer devices (including telephones) in close proximity of around a few meters within a room
• It can be used for communicating between the devices themselves, or for connecting to a larger network such as the internet
• PAN’s can be wired or wireless PAN’s can be wired with a computer
bus such as a universal serial bus: USB (a serial bus standard for connecting devices to a computer, where many devices can be connected concurrently)
PAN’s can also be wireless through the use of bluetooth (a radio standard designed for low power consumption for interconnecting computers and devices such as telephones, printers or keyboards to the computer) or IrDA (infrared data association) technologies
![Page 42: Chp 5 tech. revolutions and its effect on business](https://reader035.vdocuments.us/reader035/viewer/2022062617/54c0f2d84a7959873b8b45e3/html5/thumbnails/42.jpg)
• 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
![Page 43: Chp 5 tech. revolutions and its effect on business](https://reader035.vdocuments.us/reader035/viewer/2022062617/54c0f2d84a7959873b8b45e3/html5/thumbnails/43.jpg)
Types of Networks
Wide-area network (WAN) A network that connects local-area networks over a potentially large geographic distanceMetropolitan-area network (MAN) The communication infrastructures that have been developed in and around large citiesGatewayOne particular set up to handle all communication going between that LAN and other networks
![Page 44: Chp 5 tech. revolutions and its effect on business](https://reader035.vdocuments.us/reader035/viewer/2022062617/54c0f2d84a7959873b8b45e3/html5/thumbnails/44.jpg)
Types of Networks
Local-area networks connected across a distance to create a wide-area network
![Page 45: Chp 5 tech. revolutions and its effect on business](https://reader035.vdocuments.us/reader035/viewer/2022062617/54c0f2d84a7959873b8b45e3/html5/thumbnails/45.jpg)
LAN basics LAN’s can be either wired or wireless. Twisted pair, coax or
fiber optic cable can be used in wired LAN’s Nodes in a LAN are linked together with a certain topology.
These topologies include: Bus Ring Star Branching tree
A node is defined to be any device connected to the network. This could be a computer, a printer, a router, etc.
A Hub is a networking device that connects multiple segments of the network together
![Page 46: Chp 5 tech. revolutions and its effect on business](https://reader035.vdocuments.us/reader035/viewer/2022062617/54c0f2d84a7959873b8b45e3/html5/thumbnails/46.jpg)
A Network Interface Card (NIC) is the circuit board that has the networking logic implemented, and provides a plug for the cable into the computer (unless wireless). In most cases, this is an Ethernet card inserted in a slot of the computer’s motherboard
The Network Operating System (NOS) is the software (typically part of the operating system kernel) that communicates with the NIC, and enables users to share files and hardware and communicate with other computers. Examples of NOS include: Windows XP, Windows NT, Sun Solaris, Linux, etc..
![Page 47: Chp 5 tech. revolutions and its effect on business](https://reader035.vdocuments.us/reader035/viewer/2022062617/54c0f2d84a7959873b8b45e3/html5/thumbnails/47.jpg)
Types of Networks
Ethernet The industry standard bus technology for local-area networks
![Page 48: Chp 5 tech. revolutions and its effect on business](https://reader035.vdocuments.us/reader035/viewer/2022062617/54c0f2d84a7959873b8b45e3/html5/thumbnails/48.jpg)
Network Topologies
Bus Topology Each node is connected one after the other (like christmas
lights) Nodes communicate with each other along the same path
called the backbone
![Page 49: Chp 5 tech. revolutions and its effect on business](https://reader035.vdocuments.us/reader035/viewer/2022062617/54c0f2d84a7959873b8b45e3/html5/thumbnails/49.jpg)
Ring Topology The ring network is like a bus network, but the “end” of the
network is connected to the first node Nodes in the network use tokens to communicate with each
other
Backbone
![Page 50: Chp 5 tech. revolutions and its effect on business](https://reader035.vdocuments.us/reader035/viewer/2022062617/54c0f2d84a7959873b8b45e3/html5/thumbnails/50.jpg)
Star Topology Each node is connected to a device in the center of the
network called a hub The hub simply passes the signal arriving from any node to
the other nodes in the network The hub does not route the data
Hub
![Page 51: Chp 5 tech. revolutions and its effect on business](https://reader035.vdocuments.us/reader035/viewer/2022062617/54c0f2d84a7959873b8b45e3/html5/thumbnails/51.jpg)
Branching Tree Topology
![Page 52: Chp 5 tech. revolutions and its effect on business](https://reader035.vdocuments.us/reader035/viewer/2022062617/54c0f2d84a7959873b8b45e3/html5/thumbnails/52.jpg)
Access Control Methods
Two primary access control methods exist for computers to communicate with each other over the networkToken based accessCarrier Sense Multiple Access with Collision
Detection (CSMA/CD)
![Page 53: Chp 5 tech. revolutions and its effect on business](https://reader035.vdocuments.us/reader035/viewer/2022062617/54c0f2d84a7959873b8b45e3/html5/thumbnails/53.jpg)
Token based access
Used in bus and ring network topologies (token ring)Each computer in the network can only send its data
if it has the token. This prevents collisions that occur when data is sent at the same time over the network
The token is a special pattern of bits/bit in a frame that is directly detectible by each node in the network
A computer may only transmit information if it is in possession of the token
The message is sent to all other computers in the network
![Page 54: Chp 5 tech. revolutions and its effect on business](https://reader035.vdocuments.us/reader035/viewer/2022062617/54c0f2d84a7959873b8b45e3/html5/thumbnails/54.jpg)
Types of LAN’s
The three most popular types of LAN’s are:Token ringEthernetFDDI (Fiber Distributed Data Interface)
![Page 55: Chp 5 tech. revolutions and its effect on business](https://reader035.vdocuments.us/reader035/viewer/2022062617/54c0f2d84a7959873b8b45e3/html5/thumbnails/55.jpg)
Operation of token ring
As an example, suppose node # 1 wants to send information to node # 4 over the network
Initially, an empty frame (network packet) circulates in the network

Let’s see an animation of the token ring
![Page 57: Chp 5 tech. revolutions and its effect on business](https://reader035.vdocuments.us/reader035/viewer/2022062617/54c0f2d84a7959873b8b45e3/html5/thumbnails/57.jpg)
CSMA/CD
Usually used in a bus topology Used in Ethernet LAN’s Unlike the token ring, all nodes can send whenever they have
data to transmit When a node wants to transmit information, it first “listens” to the
network. If no one is transmitting over the network, the node begins transmission
It is however possible for two nodes to transmit simultaneously thinking that the network is clear
When two nodes transmit at the same time, a collision occurs The first station to detect the collision sends a jam signal into the
network Both nodes back off, wait for a random period of time and then re-
transmit

Fiber-Distributed Data Interface (FDDI)
Fiber-Distributed Data Interface (FDDI) provides a standard for data transmission in a local area network that can extend in range up to 200 kilometers (124 miles).
The FDDI protocol uses as its basis the token ring protocol.
In addition to covering large geographical areas, FDDI local area networks can support thousands of users.
As a standard underlying medium it uses optical fiber (though it can use copper cable, in which case one can refer to CDDI).
FDDI uses a dual-attached, counter-rotating token-ring topology.
![Page 62: Chp 5 tech. revolutions and its effect on business](https://reader035.vdocuments.us/reader035/viewer/2022062617/54c0f2d84a7959873b8b45e3/html5/thumbnails/62.jpg)
Fiber-Distributed Data Interface (FDDI)
An FDDI network contains two token rings, one for possible backup in case the primary ring fails.
FDDI has a larger maximum-frame size than standard 100 Mbit/s ethernet, allowing better throughput.
A small number of devices (typically infrastructure devices such as routers and concentrators rather than host computers) connect to both rings - hence the term "dual-attached".
Host computers then connect as single-attached devices to the routers or concentrators.

Advertising Model
The web advertising model is an extension of the traditional media broadcast model. The broadcaster, in this case, a web site, provides content (usually, but not necessarily, for free) and services (like email, IM, blogs) mixed with advertising messages in the form of banner ads. The banner ads may be the major or sole source of revenue for the broadcaster. The broadcaster may be a content creator or a distributor of content created elsewhere. The advertising model works best when the volume of viewer traffic is large or highly specialized.

The manufacturer or "direct model", it is predicated on the power of the web to allow a manufacturer (i.e., a company that creates a product or service) to reach buyers directly and thereby compress the distribution channel. The manufacturer model can be based on efficiency, improved customer service, and a better understanding of customer preferences. [Dell Computer]

Affiliate Model
In contrast to the generalized portal, which seeks to drive a high volume of traffic to one site, the affiliate model, provides purchase opportunities wherever people may be surfing. It does this by offering financial incentives (in the form of a percentage of revenue) to affiliated partner sites. The affiliates provide purchase-point click-through to the merchant. It is a pay-for-performance model -- if an affiliate does not generate sales, it represents no cost to the merchant. The affiliate model is inherently well-suited to the web, which explains its popularity. Variations include, banner exchange, pay-per-click, and revenue sharing programs. [Barnes & Noble, Amazon.com]

Community Model
The viability of the community model is based on user loyalty. Users have a high investment in both time and emotion. Revenue can be based on the sale of ancillary products and services or voluntary contributions; or revenue may be tied to contextual advertising and subscriptions for premium services. The Internet is inherently suited to community business models and today this is one of the more fertile areas of development, as seen in rise of social networking.

Subscription Model
Users are charged a periodic -- daily, monthly or annual -- fee to subscribe to a service. It is not uncommon for sites to combine free content with "premium" (i.e., subscriber- or member-only) content. Subscription fees are incurred irrespective of actual usage rates. Subscription and advertising models are frequently combined.

Utility Model
The utility or "on-demand" model is based on metering usage, or a "pay as you go" approach. Unlike subscriber services, metered services are based on actual usage rates. Traditionally, metering has been used for essential services (e.g., electricity water, long-distance telephone services). Internet service providers (ISPs) in some parts of the world operate as utilities, charging customers for connection minutes, as opposed to the subscriber model common in the U.S.
