Expect five gadgets are organized in a work topology. What number of links are required? What number of ports are required for every gadget? 3. What is the distinction between a web and the Internet? 4.When a gathering makes a neighborhood call to another gathering, is this a point-to-point or multipoint association? Clarify your answer. 5. You have three PCs associated by an Ethernet center at home. Is this a LAN, a MAN, or a WAN? Clarify your answer. 6. In a transport topology and ring topology of 8 gadgets, what occurs on the off chance that one of the hubs is unplugged? 7. Match the accompanying to at least one layers: a. Course assurance b. Stream control c. Gives access to the end client d. Characterizes outlines e. Mechanical, electrical and useful interface f. Set up, oversees and ends meetings 8.What are the obligations of the system layer in the Internet model? 9. What is the contrast between a port location, an intelligent location and a physical location? 10. Characterize period. Characterize recurrence. 11. In Europe, the force they use at home has a recurrence of 50Hz. What is the time of the sine wave in ms? 12. The recurrence of a sign is 140 KHz, ascertain the comparing time frame. 13. The time of a sign is 12 miniaturized scale seconds, what is its recurrence? 14. The time of a sign is 100 ms, what is its recurrence in kilohertz? 15. Discover the information bit stream of the accompanying diagrams [pic][pic] 16.Draw the chart of Polar RZ plot for the bit streams, (a) 01001, and (b) 00110011001 17. Draw the chart of NRZ-L and NRZ-I conspires for the accompanying information streams (a) 111100001 and (b) 001100110101 18. Draw the diagram of Polar Manchester and Differential Manchester; Bi-stage AMI and Pseudo ternary for the bit streams, (a) 010011001 and (b) 00110011 19. A simple sign conveys 2 bits for each sign component. On the off chance that 2000 sign components are sent every second, discover the bit rate. 20. A simple sign has a piece pace of 12000 bps and a baud pace of 3000 baud. What number of information components are conveyed by each sign component?
