16、the identity of the United Kingdom of law on the identity of the living person data processing. In Britain, it is the main regulations for the protection of personal data. Although the bill itself does not mention the privacy, it is through the British law into the EU data protection directive 1995,

17、 the Directive requires Member States to protect the basic rights and freedoms, in particular their privacy, personal data processing.The bill will be the United Kingdoms law is defined as the identification of biological data processing. Government procurement and personal or corporate information,

18、 must comply with the laws and procedures of data protection, and to minimize duplication of collection. Data protection law requires that Member States to protect the basic rights and freedoms of the people, in particular the right to privacy of personal data processing. In order to ensure the legi

19、timacy of the collected information, the purpose and the scientific process of collecting legitimacy is collected.Example, Crown Catering Services company should use this behavior. It can better protect the enterprise data and information, reduce enterprise risk. For example, the establishment of th

20、e company database.

21、 become a model from which several other countries, including Canada and the Republic of Ireland, have drawn inspiration when subsequently drafting their own information security laws.The Act introduced three criminal offences:Unauthorised access to computer material.Unauthorised access with intent

22、to commit or facilitate commission of further offences.Unauthorised modification of computer material.Example, Crown Catering Services company should use the Computer Misuse Act. Companies must take adequate security measures to prevent unauthorized access. For example, the company can train the sta

23、ff of the management, and set a password for the computer. It can help companies to better protect and develop their own security.4.0 data communication systemsA local area network (LAN) is a computer network that interconnects computers within a limited area such as a home, school, computer laborat

24、ory, or office building, using network media. The defining characteristics of LANs, in contrast to wide area networks (WANs), include their smaller geographic area, and non-inclusion of leased telecommunication lines.A wide area network (WAN) is a network that covers a broad area (i.e., any telecomm

25、unications network that links across metropolitan, regional, national or international boundaries) using leased telecommunication lines. (Ban Wei, 2002 year) Business and government entities utilize WANs to relay data among employees, clients, buyers, and suppliers from various geographical location

26、s. In essence, this mode of telecommunication allows a business to effectively carry out its daily function regardless of location. The Internet can be considered a WAN as well, and is used by businesses, governments, organizations, and individuals for almost any purpose imaginable.The Internet is a

27、 global system of interconnected computer networks that use the standard Internet protocol suite(TCP/IP) to link several billion devices worldwide. It is an international network of networks that consists of millions of private, public, academic, business, and government packet switched networks, li

28、nked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries an extensive range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), the infrastructure to support email, and peer-

29、to-peer networks for file sharing and telephony.The local area network is a limited distance within the network usually within a geographic location. Wide area network is a large-scale network, which can be controlled and shared resources. It is bigger than a local area network. Internet is global,

30、the most extensive. It can obtain a large amount of information resources, to understand the market demand survey. Three data communication system has its own advantages, so it should be combined with each other, the development of enterprises will be better.5.0 Benefits of data communication system

31、sLocal Area NetworkThrough the sharing of software and hardware, local area network can reduce the cost. Therefore, companies can share resources, such as printers, to save costs. Secondly, the local area network provides an opportunity to communicate with others, which means that the manager can co

32、mmunicate with the local area network more easily. Third, local area network allows companies to set permissions, so different levels of management can share different information and files.Wide Area NetworkWAN is more convenient, when a company needs a long distance communication. Wide area network

33、 transmission speed is good, the transmission of large amounts of data. and transmission range is wider .It can help companies solve the problem of remote communication and management. In addition, the wide area network can save time and money.InternetThe Internet provides a wealth of information resources and se
