Task 1.1:        

Describe how the internet operates and give 8 examples of how it is used by several selected contrasting business organisations.

How the internet works.

The internet and the worldwide web

The World Wide Web and the internet is not the same thing, and they are often confused with being the one and same.

However, the internet existed long before the www (World Wide Web).

The internet refers to the massive network of computers stretching all over the world. The word internet also found its origin trough this, the word comes from the two words interconnected, and network.

Though we can all connect with each other trough internet, all the computers are not connected to the one and same mega computer. For each network there is one or several computers that hold the information that is needed to access all the information. This arrangement is known as the client-server architecture.

Servers and clients

The internet works on the basis that some computers act as ‘servers’. These computers offer services for other computers that are accessing or requesting information, these are known as ‘clients’

The term "server" may refer to both the hardware and software (the entire computer system) or just the software that performs the service. For example, Web server may refer to the Web server software in a computer that also runs other applications, or, it may refer to a computer system dedicated only to the Web server application. For example, a large Web site could have several dedicated Web servers or one very large Web server.

Internet service providers (ISPs)

An internet service provider is a business that offers Internet access service for both businesses and individuals. The main function of an ISP is to provide a link to the worldwide web. Many ISPs these days also host websites and offer email services. Examples of ISPs are Wanadoo, Tiscali and @ Home

Protocols

A protocol is a particular way of doing something. When the internet was first being developed by scientists, they made a common agreement about how computers would speak to each other. What emerged from this agreement is a set of protocols that everyone using the internet must follow, there are several different protocols which I will explain here:

Domain names

Because IP addresses are 12 digit numbers, not everyone could easily remember these names. Therefore web servers hold lists of human readable names called domain names. An example of such a domain name  would be http://www.msn.com.

Internet Society

The Internet Society is a global voluntary group that works to coordinate and develop an accessible Internet and its underlying technology. It was founded in 1992 and is based in Virginia, USA.

Worldwide Web Consortium (WC3)

Although no one actually owns the worldwide web, there are leading bodies which try to ensure it develops in an open and accessible way, so that it will benefit as many people as possible. A major contributor is the Worldwide Web Consortium and they amongst others attempt to define web standards. A web standard is made up of elements and structures. The purpose of developing a core of web standards is to ensure as far as possible that web based content is designed and structured in such a way that the greatest benefit will be gained by the greatest number of web users.

Networking of computers

In the simplest terms, a network consists of two or more computers that are connected together to share information. All networking, no matter how complex, builds off this simple system. Though this may seem like a basic idea, the concept was a major achievement in communications.

Computer networks have spread fast, they have revolutionized they way we live and do business. Networking technology -how we create networks- is also still improving.

So a network is basically a series of computers that connect with each other, either trough cables or wireless.

Intranet

The intranet is a private network inside an organization that conforms to the same standards as the Internet but that is only for use inside the organization. The intranet will only be accessible to those members or employees who have authorization to use it. Its web sites may look and act exactly like those found on the Internet, but they are designed so that they cannot be accessed without proper authorization. So when an organisation confines its own network, we call this an intranet. This network is only accessible to people within the organisation.

Extranet

The extranet is a private network that uses the Internet protocols and the public telecommunication system to securely share part of a business's information or operations with suppliers, vendors, partners, customers, or other businesses. An extranet can be viewed as part of a company's Intranet that is extended to users outside the company. This is almost the same as an intranet, when the intranet is protected with a password, and accessible from the outside, then it becomes an extranet.

Apart from the different types of networks, we also have different types of technology that form the computer networks.

Wireless networks

While the term wireless network may technically be used to refer to any type of network that is wireless, the term is most commonly used to refer to a telecommunications network whose interconnections between nodes is implemented without the use of wires, such as a computer network (which is a type of communications network). Wireless telecommunications networks are generally implemented with some type of remote information transmission system that uses electromagnetic waves, such as radio waves, for the carrier and this implementation usually takes place at the physical level or "layer" of the network. (For example, see the Physical Layer of the OSI Model).

Wi-Fi (Wireless Fidelity)

This technology uses no physical wires in connecting computers with each other.

The name Wi-Fi originates from the words Wireless Fidelity, it uses specified radio frequencies to send and receive data. These days, more and more wireless laptops are being used, they have to be connected and able to work with Wi-Fi. These laptops contain wireless access cards that are able to connect to other cards on other laptops directly, hereby creating a point to point connection. The main advantage about Wi-Fi is that it uses no wires, so no more unhandy wires under carpets inside the house.

Bluetooth

Bluetooth is a low speed, short range wireless, protocol designed to allow a variety of enabled gadgets to connect with each other. If a device has a Bluetooth chip installed and is within 10 meters of another device with a Bluetooth chip installed, they can connect with each other using a small “personal area network”. Once the devices are connected, each of the device announces their presence on the network after which they can exchange files with each other.

Now that I have explained how networks work, I will explain even more alternate ways of connecting.  A reporter in September 2006, by Informa Telecoms and Media, predicted that by the end of 2006 there would be 2.1 billion mobile subscribers. Mobile web communication is going to be big business in the near future, so here I’m going to tell something about this new technologies.

PDA (Personal Digital Assistant)

Personal digital assistants (PDAs) are handheld computers, but have become much more versatile over the years. PDAs are also known as pocket computers or palmtop computers. PDAs have many uses: calculation, use as a clock and calendar, accessing the Internet, sending and receiving E-mails, video recording, typewriting and word processing, use as an address book, making and writing on spreadsheets, scanning bar codes, use as a radio or stereo, playing computer games etc. Newer PDAs also have both color screens and audio capabilities, enabling them to be used as mobile phones (smart phones), web browsers, or portable media players. Many PDAs can access the Internet, intranets or extranets via Wi-Fi, or Wireless Wide-Area Networks (WWANs). Many PDAs employ touch screen technology.

3G mobile phones

The 3G phones are the ‘third’ generation of mobile phones. These devices use WAP (Wireless Application Protocol) technology to offer an ‘always on’ connection to data service as well as a range of other features. These phones are able to send and receive data by connecting to the internet, although they connect much slower then their broadband counterparts.

Smart phones

A smart phone is either a PDA that has a mobile phone capabilities or a mobile phone with PDA features. A smart phone therefore combines the feature of both.

Uses of the internet and word wide web by business organisations.

The web is now a key aspect of business life for a growing number of businesses. Nevertheless, there are still some large businesses today that do no have a website; the could be called ‘site less’ or ‘sightless’ if you prefer. Eventually, all business will be on the Internet. They will all have a ‘ web presence;  I. In just about every case, their websites will be interactive, meaning that visitors can make use of the information, change it and get something back.

We saw earlier that the Internet is a lot older than the world wide web. However, it’s the ‘web;’ that has made the Internet such a valuable tool for business. This is because business can do many things using the Internet and the world wide web.

Procurement

This means buying. Businesses that are seeking to make profits have to ‘procure’ the thing they need to pursue their activities.

Research

Businesses need to be aware of things that are happening around them. Modern business managers are under increasing pressure to provide everything that customers need or want. They have to be competitive in their market, otherwise they risk being overtaken by events.

Promotion

Businesses have increased spending on Internet advertising, particularly using banner ads and pop-ups. The newer mobile channels are a big potential advertising opportunity too, with some new techniques employed to persuade people to look at the ads.

Customer service

Customers service is about meeting the needs and wants of every single customer. Businesses may have exactly the same products that do exactly the same thing, so how do we choose? Today there is software that can offer businesses templates and techniques for offering excellent customer service on the Internet. People who shop online expect the very highest standards in care. Delivery, product descriptions, frequency asked questions, catalogues, images and added design services are all features of the web. ‘Contact us’ pages can also help. In a last resort, telephone contact can be made with the online business.

Uses of related mobile technology

The beauty of mobile technology is that it allows people to use information technology without being tied of the office. Many organisations have staff that work away from their office. The availability of Wi-Fi, 3G mobiles and PDAs has enabled fast communication in a much more flexible way. Mobile technology can improve the speed of service that can be offered to clients.

Uses of related mobile technology by business organisations.

Voice over Internet Protocol

VoIP services convert your voice into a digital signal that travels over the Internet. If you are calling a regular phone number, the signal is converted to a regular telephone signal before it reaches the destination. VoIP can allow you to make a call directly from a computer, a special VoIP phone, or a traditional phone connected to a special adapter. In addition, wireless "hot spots" in locations such as airports, parks, and cafes allow you to connect to the Internet and may enable you to use VoIP service wirelessly.

Increasing penetration and speed

The Internet is a global phenomenon and the numbers of people using it grows day by day. The increasing in availability and access to the internet is a major trend that encourages businesses to get online. However, there are still parts of the world where Internet ‘penetration’ –i.e. the percentage of the population who have regular Internet access- is low, as can be seen in the table below.

Connection speeds are increasing as technology improves, which makes it even more desirable for businesses and individuals.

Falling cost

Other factors can encourage greater access and use of the Internet. The cost of broadband connection is falling, which encourages more people and businesses to

use the web and get more from it.

As businesses see opportunities and realise that greater numbers of people are accessing the web, and as costs, speed and reliability continue to improve

(As they are) the Internet evolution is likely to accelerate.

Reasons why people use the Internet

How internet is used by:

Wikipedia

Wikipedia is like a huge encyclopaedia where you can do research about thousands of subjects and it is available in 10 different languages. http://

Hotmail

Email offers a cheap and easy alternative to traditional methods of correspondence. It's faster and easier than writing letters and cheaper than using the telephone. Of course, there are disadvantages too. It's not as personal as a handwritten letter and not as reliable either. http://www.hotmail.com

E-bay

Internet shopping is still in. It takes a very good marketing strategy to actually make money out of selling items over the Web, but that doesn't stop lots of people from trying. The security of on-line shopping is still questionable, but as long as you are dealing with a reputable company or Web Site the risks are minimal.  

Rabobank
