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.
A sending device initiates the transmission of data, instructions, and information while a receiving device accepts the items transmitted.
Microcomputers, minicomputers, and mainframes all can serve as sending and receiving devices.Besides, Internet appliances and Web enabled handheld computers and devices (e.g., cellular telephones and pagers) can also serve as sending and receiving devices.
3. Describe uses of computer communications.
4. List advantages of using a network.
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 you uploaded data onto5. 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 is a communications model in which each party has the same capabilities and either party can initiate a communication session.
Peer-to-peer (P2P) computing or networking is a distributed application architecture that partitions tasks or workloads between peers.
6. Describe the various network communications standards.
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. These software send and receive data over telephone lines through modems. The communication software allows computers in different geographical regions to communicate with each other through terminal emulators, file transfer programs, chat and instant messaging programs.
8. Describe various types of lines for communications over the telephone network.
9. Describe commonly used communications devices.
Radio Telephone systems Pagers Navigation systems PDA's (Personal Digital Assistant) Computer10. Discuss different ways to set up a home network.
Wired Network
To set up a home network that is wired, you will need to have a network card in each computer, a router, and enough cables to connect them all. You will also need the documentation that came with your router.
- Step 1 - Connect the cable from your internet modem to the port on the router labeled either uplink, or internet in most cases.
- Step 2 - Connect the first computer to anyone of the other ports.
- Step 3 - Log into your router refer to the information that came with your router. This is usually done by entering 192.168.0.1 or 192.168.1.1 into your address bar. Your documentation will tell you which one.
- Step 4 - Enter the username and password that is instructed by your router documentation.
- Step 5 - You should now be in the router setup. Enter all the information for internet, you will need the protocol, PPPoE in this case, the username and password from your internet service provider. Click on Save when done.
11. Identify various physical and wireless transmission media.
For physical transmission Media there are:
Twisted-Pair Cable Coaxial Cable Fiber-Optic CableFor wireless trasmission media there are:
Broadcast Radio Cellular Radio Microwaves
