Data Communication

A strong data communication system relies on many factors. In addition to the individual components of which it is made, it relies on and is propelled by networking systems. In this assignment, you will look at a real-life example of a data communication system. Refer to the “Case Study: Data Communication at Walmart” on pages 134-135 of your textbook as you complete this assignment.

Write a 1-2 page paper that includes the following components:

Answer Questions 1-4 (See Below)

Assess what the likely components of Walmart’s system are.

Explain how various networking concepts (bandwidth, routing, routers, and the client/server model) either are being or could be used to meet Walmart’s networking needs.

This should be in original content and please reference any references used. Total pages is 2 - 2.5

Below is the Case study

CASE STUDY 6-1 Data Communication at Walmart

Walmart has made several changes in its data communication systems to improve its suppliers' access to sales and inventory data. For example, the company added a customized Web site for its suppliers, such as Mattel, Procter & Gamble, and Warner-Lambert. Walmart's goal is to improve efficiency in order to keep prices low and maintain a high level of customer service. With WaImart's network, suppliers can access sales, inventory, and forecasting data over extremely fast connections. To ensure confidentiality of data, a sophisticated security system has been implemented to prevent suppliers from accessing data about one another's products.

Walmart has also added Web-based access to its RetailLink system so suppliers can use information in the database. Other data communication applications at Walmart include automated distribution, computerized routing, and electronic data interchange (EDI).18,19

Walmart uses the latest in wireless technology in its operations for warehouse management systems (WMS) to track and manage the flow of goods through its distribution centers. Another application of wireless technology is for controlling and monitoring forklifts and industrial vehicles that move merchandise inside its distribution centers. The Vehicle Management System (VMS) is the latest application of data communication in Walmart. Among other features, the VMS includes a two-way text-messaging system that enables management to effectively divert material-handling resources to where they are needed the most. (The VMS works effectively with RFID systems.) According to Walmart, the VMS has improved safety and has also significantly improved the productivity of its operations.

Answer the following questions:

1. How has Walmart improved its data communication systems for suppliers?

2. What are some typical data communication applications at Walmart?

3. What are some of the applications of wireless technology at Walmart?

4. What are some of the features and capabilities of the VMS?
