CIE 33 REVIEW QUESTION
1. What “language” must a microcomputer talk in order to interface with the Internet?
Ans= some form of TCP/IP
2. What kind of applications might use a sensor to local area network layout?
Ans= Assembly line robotic control devices, oven temperature controls
3. Why is network architecture useful?
Ans= allows for compatibility between products and allows products to interoperates.
4. List the seven layers of the OSI model.
Ans= *Application *Presentation *Session *Transport *Network *Data link *Physical
5. List the five layers of the TCP/IP protocol suite. How do the layers of the OSI model compare with the layers of the TCP/IP protocol suite?
Ans= *Application layer: - Equivalent to OSI application and presentation layers. *Transport layer: - Equivalent to OSI transport layer. *Network Layer: - Equivalent to OSI network layer. *Network Access: - Equivalent to OSI data link and physical layers.
6. What are some of the more common applications found in the TCP/IP protocol suite?
Ans= Hypertext Transfer Protocol (HTTP) to allow Web browsers and servers to send and receive World Wide Web pages
■ Simple Mail Transfer Protocol (SMTP) to allow users to send and receive electronic mail
■ File Transfer Protocol (FTP) to transfer files from one computer system to another
Telnet to allow a remote user to log in to another computer system
■ Simple Network Management Protocol (SNMP) to allow the numerous elements within a computer network to be managed from a single point
7. What is the difference between a logical connection and a physical connection?
Ans= In logical connection exist only in the software, while a physical connection is one that exist only in hardware
8. How does convergence apply to the communications industry?
Ans= In form of media press and public speaking.
9. What is the decibel loss of a signal that starts at point A with a strength of 2000 watts and ends at point B with a strength of 400 watts?
Ans= 10*log10
