Chapter 1. The TCP/IP and OSI Networking Models Page 1 of 22 Chapter 1. The TCP/IP and OSI Networking Models This chapter covers the following exam topics: Operation of IP Data Networks Recognize the purpose and functions of various network devices such as Routers‚ Switches‚ Bridges and Hubs. Select the components required to meet a given network specification. Describe the purpose and basic operation of the protocols in the OSI and TCP/IP models. Welcome to the first chapter in your

Data in 4G traffic is centric‚ data traffic channel increase instead of voice traffic channels. In wireless link user demand for services with the implementation of Asymmetric Digital Subscriber Line (ADSL) and fiber optic access system. System designer for wireless communication system need to cope the problemS

1 What are two reasons for physical layer protocols to use frame encoding techniques? (Choose two.) to identify where the frame starts and ends* to distinguish data bits from control bits* to reduce the number of collisions on the media to increase the media throughput to provide better media error correction 2 Which statement is correct about multimode fiber? Multimode fiber commonly uses a laser as a light source. Multimode fiber cables carry signals from multiple connected sending

model divided into layers To make it easier to understand how networks work‚ write protocols for networks‚ and to create standards for networks 13. Why is the TCP/IP considered an "open" network model It is not owned by any specific organization and shares details of how it works with all 14. The function of a Routers in networking is to Move data between separate LAN’s‚ often by linking them to WAN lines in a network 15. What is "Encapsulation" A way to address data to cross over any

Which of the following protocols are examples of TCP/IP network access layer protocols? B. Ethernet(Missed) C. PPP(Missed) 3. The process of HTTP asking TCP to send some data and make sure that it is received correctly is an example of what? B. Adjacent-layer interaction(Your Answer) 4. The process of TCP on one computer marking

the following: o On which layers of the OSI model do WAN protocols operate? o What are some of these protocols? o On which OSI layers do switches and routers operate? o If routers reside at more than one layer‚ what is the difference between the OSI layers? When one looks at the seven layers of the OSI model‚ one can determine that layer three is where the WAN protocols operate on. Layer three is known as the Network Layer. The Network Layer performs several routing functions

Concept/NTC-360 June 19‚ 2011 Fernando Casafranca Here are the short answer responses for the following terms: • Synchronous and asynchronous 1 SYNCHRONOUS Synchronous systems negotiate the communication parameters at the data link layer before communication begins. Basic synchronous systems will synchronize both clocks before transmission begins‚ and reset their numeric counters for errors etc. More advanced systems may negotiate things like error correction and compression.
