The Internet is a global system of interconnected computer networks that use the standardized Internet Protocol Suite (TCP/IP) to serve billions of users worldwide. It is a network of networks that consists of millions of private and public, academic, business, and government networks of local to global scope that are linked by copper wires, fiber-optic cables, wireless connections, and other technologies. The Internet carries a vast array of information resources and services, most notably the inter-linked hypertext documents of the World Wide Web (WWW) and the infrastructure to support electronic mail. In addition it supports popular services such as online chat, file transfer and file sharing,gaming, commerce, social networking, publishing, video on demand, andteleconferencing and telecommunications. Voice over Internet Protocol (VoIP) applications allow person-to-person communication via voice and video.

The origins of the Internet reach back to the 1960s when the United States funded research projects of its military agencies to build robust, fault-tolerant and distributed computer networks. This research and a period of civilian funding of a new U.S. backbone by the National Science Foundation spawned worldwide participation in the development of new networking technologies and led to thecommercialization of an international network in the mid 1990s, and resulted in the following popularization of countless applications in virtually every aspect of modern human life. As of 2009, an estimated quarter of Earth’s population uses the services of the Internet.

When the internet was first created?

In 1973, the U.S. Defense Advanced Research Projects Agency (DARPA) initiated a research program to investigate techniques and technologies for interlinking packet networks of various kinds. The objective was to develop communication protocols which would allow networked computers to communicate transparently across multiple, linked packet networks. This was called the Inter netting project and the system of networks which emerged from the research was known as the “Internet.” The system of protocols which was developed over the course of this research effort became known as the TCP/IP Protocol Suite, after the two initial protocols developed: Transmission Control Protocol (TCP) and Internet Protocol (IP).

Which country was responsible for the idea of the internet?

What is an ISP(internet service provider)?

An ISP might provide dial-up service, cable, DSL, or other types of Internet access. Some ISPs are local while others are national. A national ISP will provide access throughout most of the nation, while a local ISP will only serve subscribers in a limited geographical region.

Who was the first ISP?

What is a Web Browser?

A web browser is a software application for retrieving, presenting, and traversing information resources on the World Wide Web. An information resource is identified by a Uniform Resource Identifier (URI) and may be a web page, image, video, or other piece of content.^[1] Hyperlinkspresent in resources enable users to easily navigate their browsers to related resources.

Although browsers are primarily intended to access the World Wide Web, they can also be used to access information provided by web servers in private networks or files in file systems.

The major web browsers are Internet Explorer, Mozilla Firefox, Apple Safari, Google Chrome, and Opera.

Find out which is the most popular browser?

1. Internet Explorer
2. Firefox

Explain what a domain name is?

A series of alphanumeric strings separated by periods, such as www.hmco.com, that is an address of a computer network connection and that identifies the owner of the address.

What is an IP address?

An Internet Protocol (IP) address is a numerical label that is assigned to devices participating in a computer network utilizing the Internet Protocol for communication between its nodes. An IP address serves two principal functions in networking: host identification and location addressing. The role of the IP address has also been characterized as follows: ”A name indicates what we seek. An address indicates where it is. A route indicates how to get there.”

What is my IP address?

202.145.1.5

What is a firewall and why is it necessary?

A firewall is a blocking device to stop others accessing something from your computer. To protect your computer hard drive.

What are the things to enable you to connect to the internet?

To connect to the internet you simply need a modem, an ethernet cable, and a high speed internet connection. the connection can be set up by your cable company, phone company, or a private Internet provider. Of course a computer is needed to view the internet but to connect you simply need the three things above.

How does broadband works?

You buy it from a internet provider than when you get the modem you plug it in and it will send signal’s down telegraph poles to the Internet Service Provider (ISP) and they will connect you then you are ready to go start surfing!!!

What does FTP stands for?

FTP stands for File Transfer Protocol. It most commonly uses ports 20 and 21.

FTP is usually used to send files from computers to hosting webservers when creating a website. It can also be used as a means of “downloading” files from other servers. FTP is sometimes used to send files from one computer directly to another.

FTP can be quite dangerous if not properly configured because malicious black-hat hackers can send trojans or other spyware to unsuspecting users or sites. Most firewalls do a reasanable job of protecting against this type of attack.

To use ftp, you need an ftp program. Many good ones are free including:

• Cute ftp
• Secure ftp
• Smart ftp

b) We should gather the wires in a secure place where nobody will trip on them.

health and safety at work

2.) Investigation and Analysis- Once the company have identify the problem, the company will start to investigate how the old system works and the problem it is causing by using some variety of techniques that include:

 Questionnaires and interviews

 Observing people actually using the existing system

 Paper trail

 Once the company have investigate the problems, the company will then carefully analyse how the existing systems work. They will look at alternative methods such as:

 System Diagrams

 Data Flow Diagrams

 Process diagrams

3.)Design the system- Now that the company have agreed on the requirements, designing the system will take place. In the design phase, the screen layout is designed, the error messages are written, menu buttons are chosen, Font style, Size, and color are picked, what documents to be printed out and what hardware will be needed.

4.)Develop the system- This phase is where the system starts to be written by the software programmers. They follow the requirements specification from the design stage and start to create the new system.

 5.)Test the system- Once the system has been coded, it need to be tested by a team of testers to see if the system is working properly.

6.)Evaluate the system- Now that the system is up and running for real, it is important to evaluate it.
