1. What purpose does the OSI stack perform? Is used by equipment vendors, Internet services providers and cable television (catv) service provides when designing and implementing telecommunications networks. 3. What are the advantages of organizing the functions of th OSI module into layers?
TCP is the transport layer protocol that links the application layer to the network layer. TCP breaks the data into smaller packets, numbers the packets, ensures each packet is reliably delivered, and puts the packets in the proper order at the destination. IP is the network layer protocol and performs addressing and routing. IP software is used at each of the computers through which the message passes through; IP routes the message to the final destination. TCP/IP is the transport & network layer protocol used on the Internet.
Also, the Customer Tracking System’s ability to interface with Webstore is important to the project. a. What entities are identified in the previous scenarios? Can you think of additional entities? What interrelationships exist between the entities?
The first is a T-1 link and the second is a 128-Kbps link. When setting up the site links for replication, what should you do to ensure that the 128-Kbps link is used only if the T-1 is unavailable? A: Set a cost of 1 for the T-1 and a cost of 5 for the 128-Kbps link. 4. You are a consultant working on a site plan for a medium-sized organization.

An entity relationship diagram (ERD) is a tool that depicts the flow of data through a system and the work or processing performed by that system. Answer: False Page: 317 LOD: Medium Rationale: A data flow diagram (DFD) is a tool that
Networking 337 Exam 1 Cards What are properties of WANs? connects backbone networks and MANS. The _________ layer performs error checking which is redundant with the function of the _________ layer. transport, data link Which is a function of the transport layer? breaking long messages into several smaller messages The primary reason for networking standards is to: ensure that hardware and software produced by different vendors can work together ___________ refers to the spreading of the signal that different parts of the signal arrive at different times at the destination.
Prevention depends on the circuit being used. Such preventions are (Fitzgerald 124-125): 1. Shielding: insulating wires 2. Relocating Cables: Keeping network cables separate from power cables 3. Multiplexing: Based on frequency and guardbands size will require altering the FDM 4.
2) What is the main advantage of direct face-to-face communication, as against communication through circulars or memos? 3) What makes technical communication different from general communication ? 4) How important is it to be able to communicate? 1) Read the above conversation carefully if you were Vikas, how would you answer all the questions asked by the interviewer.

What data elements are and why they are important There are two different types of data elements such as: 1) Elementry data elements - Defined by the built in values of data type and lenght 2) Reference data elements - Make use of reference variables mostly used in other ABAP objects Data element is a data dictionary which can be created or modifed by using a process which is called SE11. The purpose of data elements are they are designed to find the characteristics of a table field or a component of a structure. Data element is a term where a process of the functions take place over networks just like protocols. Frames and Packets: To avoid delay during the process of transmitting data to another network, the networks change the amount of data that can be transferred across which is called switching. The amount of units that the data is sent in is called packets.
