Installing, Configuring, Managing, and Troubleshooting a PC

TComputers have become a critical part of our lives; therefore, system administrators need to ensure that the computers in their organization function smoothly at all times. For this, organizations need system administrators who have a thorough understanding of installing, configuring, and troubleshooting different computer components and peripherals, including those of laptops and personal computing devices. Since a computer cannot function with hardware alone, system administrators must also be able to install and configure operating systems. Knowledge of the fundamentals of networking, network connectivity options and methods, and network security methods enables system administrators to set up and manage networks for data sharing and communication. Since a loss or misuse of data from computers can be catastrophic, system administrators should also be able to implement security mechanisms to safeguard computers and networks from various security threats.

Fundamentals of Linux Operating System

Linux has evolved as a Unix-based operating system with GUI. It is a low-cost alternative to other expensive operating systems for small as well as large organizations and desktop users. Because of these features, many organizations are adopting this operating system and the number of Linux users is also increasing. The objective of this module is to familiarize students with the Linux platform and provide sufficient knowledge to make them power users. The end users can use shell-scripts to automate tasks in Linux using commands such as cp, mkdir, and rm. They can exchange information with other users with various utilities. Linux also offers utilities to compress and decompress files, which will enable users to reduce the size of huge files that need to be sent over the Internet.

Protocols and Internetworking Standards

Organizations are building heterogeneous, enterprise-wide networks consisting of personal computing devices such as laptops, desktops, ultra- notebooks, tabs and servers communicating via LANs, WANs, and Wireless Networks. Switches and routers are the critical building blocks for this environment. More and more companies today are moving towards building a large enterprise framework where all the branch offices and divisions are interconnected resulting in smooth flow of information via any means or media. Organizations have a separate budget allocated towards setting up and supporting a strong and robust hardware and networking infrastructure. These organizations require professionals who can manage their network and proactively handle configuration and security issues.
