Name: Date: Northampton Community College CISC 231 – Data Communications and LANs (CCNA 1) STUDY GUIDE FOR CHAPTER 2 1. What is the purpose of a network protocol? A network protocol defines rules and conventions for communication between network devices. Protocols for computer networking all generally use packet switching techniques to send and receive messages in the form of packets. 2. Define the role of an intermediary device in the network. Communication to run smoothly across

receiver doesn ’t have to be present or aware of the sender ’s intent to communicate at the time of communication; thus communication can occur across vast distances in time and space. Communication requires that the communicating parties share an area of communicative commonality. The communication process is complete once the receiver has understood the message of the sender. 1.3 Definition Of Computer Communication Network Computer Communication Network is to allow moving information from one

in China would be simplest to interface Atlanta with a satellite. LANs at every area could be set up with Ethernet systems working at rates up to 100Mbps‚ allowing the packet switching‚ latency‚ and the channel capacity to be more efficient. In packet switching‚ data is separated into smaller bundles before being conveyed. Having smaller bundles allows every bundle to pick their own particular ways to the planned area‚ this permits resources to be reallocated as the needs grow. ACME will require

Logical and Physical Network Design Logical and physical network designs are critical components in the successful development and implementation of today ’s networks and allow for the proper planning and structuring bettering enhancing the concept associated with networks. In order to better understand how the two concepts of a logical design and physical design work hand-in-hand‚ let ’s first look at what the concepts entail. A logical design is a concept‚ thought or theory as to how you

down. Kudler faces challenges that includes redundancy in the network‚ loss of data‚ viruses‚ hackers‚ and a backup connection. Each store will maximize efficiency of how computers communicate by installing a WAN (wide area network)‚ LAN (local area network)‚ or WLAN (wide local area network). The company is upgrading to a Cseries aggregation service router as a WAN solution. The router delivers many advantages such as high performance‚ integrated software enabled services‚ and software redundancy

there is no hands on training associated with the course. I do not feel like concepts and design ideas are a great resource to actually learn how to use any of the systems but they do give a pretty good idea. Cabling SpecificationsEthernet is a Local Area Network (LAN) technology with a transmission rate of 10 Mbps and has a typical star topology. Computers and devices must wait-and-listen for transmission time on the network as only one device can transmit at any one time. In order to operate with

Chapter 7 Lab Exercise 7.1.1 Part of the distinction between LAN and WAN networks is ownership. Why is it impractical for an organization to own the entirety of a WAN? Why is it favorable for an organization to maintain ownership of the entirety of a LAN? Use your textbook and Internet research to compose your answer A) There are no limitations on WANs so they can be custom built for the size of the organization. For the purpose of organizational expansion. Exercise 7.1.2 Given the problems with
