QUIZ 7

1. Discuss the components required for successful communications.

Sender, beneficiary, and a atmosphere. That's in the order of the most chief definition of the components of computer network.

2. Identify various sending and receiving devices.

Sending device initiates the transmission of data, instructions, and information while a receiving device accepts the items transmitted.

·        Microcomputers

·        Minicomputers

·        Mainframes

·        Internet appliances and web enabled handheld computers

3. Describe uses of computer communications.

Computer-mediated communication (CMC) is defined as any communicative transaction that occurs through the use of two or more networked computers^.While the term has traditionally referred to those communications that occur via computer-mediated formats (e.g., instant messages, e-mails, chat rooms), it has also been applied to other forms of text-based interaction such as text messaging^. Research on CMC focuses largely on the social effects of different computer-supported communication technologies. Many recent studies involve Internet-based social networking supported by social software.

 4. List advantages of using a network.

-share software

-share information with others on networks

-share peripherals

-speed of sharing software and information files

-cheaper than buying individual software and hardware for each standalone especially -if for a school, network software often offers deals for amount being purchased

-security, files can be copy inhibit mode

-centralized software management- software being loaded onto one computer but also -this loads software to entire network at one time

-electronic mail(e-mail) between network users, ideal for office memos

-flexible access- access you files from any computer on the network unlike standalone -which would mean only being able to access your data from the one computer youuploaded data onto

 5. Differentiate among client/server, peer-to-peer, and P2P networks.

Client/server-describes the relationship between two computer programs in which one program, the client, makes a service request from another program, the server, which fulfills the request.

Peer-to-peer (P2P)-computing or networking is a distributed application architecture that partitions tasks or workloads between peers. Peers are equally privileged, equipotent participants in the application. They are said to form a peer-to-peer network of nodes.

6. Describe the various network communications standards.

Networks may be classified according to a wide variety of characteristics such as medium used to transport the data, communications protocol used, scale, topology, organizational scope.

7. Explain the purpose of communications software.
Communication software is used to provide remote access to systems and is also used to exchange messages in text, audio and video format for the purpose of communication.

8. Describe various types of lines for communications over the telephone network.

Telex, Fax and dial-up Internet communication.

9. Describe commonly used communications devices.

Radios are communication systems that send and/or receive electromagnetic waves and consist of a transmitter, receiver, and antenna. Pagers are electronic communications devices that are used to notify or alert a user. Other types of communication devices include navigation systems, such as global positioning systems (GPS) instruments and radar systems. GPS communication devices receive satellite communications and use it to provide position information. Radar communication devices use synchronized transmitters and receivers to send radio waves and detect their reflections from objects, surfaces and sub-surface structures.

10. Discuss different ways to set up a home network.

Home Network Overview

11. Identify various physical and wireless transmission media.

Transmission media - Enables computers to send and receive signals to one another
