Course Project Part 4—Memory Management and Virtual Memory

Continuing with the course project, this week, you will study how various OSs perform memory management and provide support for virtual memory.

Tasks

Using the South University Online Library or the Internet, research memory management, virtual memory of OSs, deadlock modeling, and distributed OSs.

Based on your research, complete the following tasks:

• For the scenario at Acme Toys Inc. described in Week 1, read the requirements again. In the Microsoft Word document from W3 Assignment 2, to your analysis of OSs (three OSs for workstations and servers), add to the discussion with regard to memory management, virtual memory, deadlock modeling, and distributed OSs. Support your analysis with reasons.
• For each listed OS, discuss the requirements for size of virtual and physical memories.

Support your responses with examples.

Scenario:

Acme Toys, Inc. is a leading toy manufacturer. As part of its expansion plan, it purchased a new building for its headquarters, which will house all the departments of the company. Apart from the usual departments, such as marketing, sales (with telemarketing capability), accounting, and IT, the building will also house the R&D, manufacturing, and distribution departments.

The company wants to set up a network to enable employees to communicate and share resources. The company requires workstations and server computers. The servers should provide support for:

• A multiuser environment
• Multiple processors
• Various types of applications
• High security
• High memory requirements

In addition, the network should be able to support high-level, multiuser applications that will run simultaneously. The profiles of employees range from a sales executive who is not computer savvy to IT professionals and people in the R&D department who are technology savvy. Due to the diverse user profiles, the company also needs to consider the ease of use of the OS.

The IT department is in the process of designing the processing requirements of computers. Although the entire company will be networked, a separate network is required for the R&D department because of security reasons. In addition, the manufacturing department plans to expand its network within the next six months by fifty percent.

As a member of the IT team, you need to recommend the best OSs for workstations and servers on the network. You need to consider the ease of use of various OSs based on user profiles. Your report must provide a rationale for the proposed OS and compatibility issues, if any, if you propose using multiple OSs.
