Asymmetric Digital Subscriber Line

communication networks by utilizing the different security protocols as well as protecting data of the computer systems. Symmetric-key ciphers and public key ciphers find their applications in fields governing data encryption, authentication and digital signatures. Further becoming an essential part of the embedded systems involving programmable network devices as there is a rise in the connectivity of the networks which increases the role of cryptography algorithms from servers to sensors and smartcards

1–10 Mbps downstream and 256 Kbps to 1 Mbps upstream.” Since the capacity is shared, a user can only see this when no other computers on their segment are active. (Fitzgerald, 348-349). Wireless DSL is a type of fixed wireless which requires a line of sight between communicating transmitters. Unfortunately; this makes its application limited, because in order to be effective, it requires tall buildings or towers. Most multitenant buildings such as hotels, remote office buildings and apartments

Asymmetric cryptographic algorithms, such as RSA, encrypt symmetric keys in key exchange protocols and in hybrid cryptographic systems. Furthermore, entities A and B can now use end-to-end confidentiality and integrity services without the cooperation of any third entity. For example, users can exchange secure e-mail and securely access Web content on an intranet without the immediate cooperation of a mediating server such as CA. Author in [17] introduced a new combined cryptographic method called

Network operating systems also have their own protocols

a. Explain how the bank organization could be benefited due to the implementation of computer networks and how the resources could be utilized in an efficient manner with the computer network  The Benefits of having computers networks for organisation are: • Users can access their files from any network. Within the network covered, expensive devices such as laser printers or scanners can be shared. • The software and resources within the area of networks can be well organized and centrally managed

Oligopolistic is a market structure which under the imperfect competition. According to Sloman & Garratt, oligopoly is only few large firms share a large portion of industry and control the market. When we hear that a term about “Big three”, “Big four” or “Big five” it can be set down as oligopolistic industry. In the oligopoly market competition, depends on the firms produce homogeneous or differentiated products and it will be categorize as homogeneous oligopoly or differentiated oligopoly. As

INTRODUCTION In this assignment I will talk about internet services, describe a few computing terms as HTTP, WWW and other, then I will talk about security and what could cause the trouble on your machine and then, I will put all of the useful links in bibliography. WEB ARCHITECTURE Internet Service Providers (ISP) To connect to the Internet, you need an ISP. It is the company that pay for each months to use the Internet. If you use a modem to connect to your ISP, (point-to-point protocol) connection

Techniques for transmitting a digital signal over an analogue medium include: a) Frequency c) Amplitude e) None of the above b) Phase d) All of the above 4.A paradigm for electronic communications where a message is broken up into blocks of data of limited size which are then transmitted one

packet switching technology and it’ networks are connection-oriented which is useful to gather information regarding circuit switching. It supports integration of voice, data services, and video on a single network. ADSL is stand for Asymmetric Digital Subscriber Line (ADSL) which is used data related residential service. Which means layer 3 packet is segmented into fixed length 53byte cells, in it 48 bytes of information and 5 bytes of header (overhead) information. So that it allows very fast switches

A local area network (LAN) is a computer network that connects computers in an area with limited space such as a home, school, computer laboratory, or office building, using network media. A Wide Area Network, or WAN, is made up of many computer networks connected together, often over the Internet. In most cases, the networks in WANs all belong to the same company or school. A Metropolitan area network, or MAN for short, is a computer network that connects multiple other Local area networks (LANs)
