LITERATURE REVIEW
WHAT IS INTERNET
The internet is a vast network of computer networks. A wide world collection of network and gateways that uses the TC/IP suite of protocols of communication with each other according to cashman and shally (2000), the internet is not owned or founded by any one individual, institution, organization or government. It is not a commercial service. The internet is however directed by the internet society (ISOC).
ORIGIN OF THE INTERNET
In late 1960’s a group of scientists at the US department of Defense Advanced Research Project Agencies (ARPA) wanted to share information with others working on similar research project many of whom were government contractors working at universities.
Thus ARPA net was developed to link this university. When people at this institution discovered the enormous utility of a network that linked them with their colleagues around the world the project mushroomed.
As the network expanded through the 1970’s members of the computer industry began to participate and the internet became an online heaven for computer researchers and academics. This decentralized network called ARPA net created by the Department Of Defense in 1969 to facilitate communication in the event of a nuclear attack was eventually linked to other network including Bitnet, Usenet and NStnet thus forming what is called the internet (www. Ask.com)
SERVICES PROVIDED BY INTERNET
There are several or quite a number of services provided by the internet that make it easier to share information. They are:
WWW: Stands for the World Wide Web. This part of the net contains the website you can visit. You can see web pages with the help of special program called browser with the help of a gently used browser. The most frequently used browser are Microsoft internet explorer and Netscape navigator both are free.
Website owners can submit relevant keywords, title and descriptions for their sites to search engines, directories or guides. These are special sites that do nothing but index and categorize other web site by key words title descriptions so you can search for them.
E-MAIL: E-mail stands for electronic mail it’s the most used marketing vehicle on the internet. This easy to function combines text processing and the possibilities. A mail box at your ISP receives and stores electronic messages that you download once you are connected. And you can send electronic messages to others. Your ISP will give detail on how to set the parameter for your incoming and outgoing mail boxes (French 1995)
NEWS GROUPS: Newsgroups, are meeting places for people discussing a special topic you can read and send messages about the topic. There are newsgroups about almost any kind of subjects. The subjects are more or less categorized. You can recognize a main group of related topic by the first characters of the group.
ALT = Alternatives
BIZ = Business
REC = Recreation
Biz, forsake tells you that you can post messages to this newsgroup that are not moderated. This means that if you post message to the group it can be read, unchanged by every certain etiquette. And if your message does not comply with this your can get in real trouble. The other members may flame you which means you will receive some very nasty letters (www.ask.com).
INTERNET SECURITY
This is the practice of protecting and preserving private information’s and resources on the internet (www.ask.com)
INTERNET SECURITY PROBLEMS
Internet suffers from severe security problems and site that ignore these problems face some significant risk. That internet will attack them aim that they provide intruders with a staging ground for attacks on other networks. Even sites that do observe ground security practices face Problems with new vulnerabilities in networking software and the persistence of some intruders.
PROBLEMS OF INTERNET SECURITY
The internet has suffered from a significant and widespread security problems. A number of factors have contributed to the poor security of the internet, the lapses included:
(I) VULNERABILITY OF TCP/IP SERVICES
A number of the TCP/IP services are not secured and can be compromised by knowledgeable hackers; services used in the local area network management are especially vulnerable.
(II) CASE OF SPOOFING AND SPYING
The majority of internet traffic unencrypted mail, relatively inexpensive equipment and capture using common software can monitor password and file transfer.

SYSTEMS ANALYSIS
INTRODUCTION
In this chapter, the process carried out in each session of Access Point Communication Limited will be listed. The detailed analysis of the existing system and the data flow diagram (DFD) of the existing systems of cyber café and the computer institute sections will be discussed in this section coupled with weakness and strength. Also the reason for a new system and expectations from this new system will be discussed in this chapter.
RESEARCH METHODOLOGY
Obviously research methodology refers to the method employed in various aspect of the course of the project, the following research are adopted for the project.
- The structured system analysis and design methodology (SSADM) will be adopted throughout the analysis and design stage.
- Interviewing and discussing with the staff of internet administrators of Access Point Communication Limited (cyber café department) located at Umuahia Abia state.
DETAILED ANALYSIS OF THE EXISTING SYSTEM
Analyses are concerned with two things: the project definition and the system study, according to Sprague and Carlson (1988). The purpose of a system analysis definition in DSS construction is to identify problem and a set of capabilities that users consider helpful in arriving at decision of the matter at hand, and then the solution is sort after.
CHAPTER FOUR
SYSTEM IMPLEMENTATION AND DOCUMENTATION
SYSTEM IMPLEMENTATION
System implementation is the planned and orderly conversion from an existing system to a new one. It involves five tuning system elements in order to maximize efficiency and productivity. Parts of the task include completing documentation and evaluating the final design to make sure that the system meets designed goal and objectives.
The task list may be developed specifying what must be done: The task list for implementation of the new internet café automation system is as followed;
- Specifying hardware and software requirement
- Evaluate system test-run
- Prepare change over time table
- Under take system maintenance
CHAPTER FIVE
SUMMARY, CONCLUSION AND RECOMMENDATION
SUMMARY
In all, this project together with its fruits aimed at saving the management of Access point communication Limited, the trouble and difficulties in running an internet café manual. Apart from the many benefits acquiring from the full. Internet development software which were highlighted in the introduction chapters of this project a lot of barriers has been broken and extra feature achieved in this direction include:
