Wikipedia (http://en.wikipedia.org/wiki/Computer_literacy): Computer literacy is defined as the knowledge and ability to utilize computers and related technology efficiently, with a range of skills covering levels from elementary use to programming and advanced problem solving. Computer literacy can also refer to the comfort level someone has with using computer programs and other applications that are associated with computers. Another valuable component is understanding how computers work and operate.

We define Computer literacy as the knowledge and ability to utilize computers and related technology efficiently, with a range of skills covering information and data management, interfacing between computer and humans, programming, and advanced problem solving. We also include a basic understanding how computers work and operate.

Sessions: Every Thursday, 1:00-2:00 PMLocation: Engineering Systems Building, Room 2010A

Participation: Voluntary, no credits, but should be regularly

•Active participation in the sessions•Plan to provide problems to be solved•Can be solved with any appropriate programming language/tool•Should not use (too much) existing packages but rather be own work

Learning Goals:•have basic understanding of how computers work and operate•be able to select level of using computers appropriately for a given problem•have the skills to analyze a problem, prepare methodology to solve the problem using computers•be capable of coding algorithms in a preferred coding language and test/validate the application

Operating system: “An operating system (OS) is software that manages computer hardware and software resources and provides common services for computer programs. The operating system is an essential component of the system software in a computer system. Application programs usually require an operating system to function.”

Application: Application software is a set of one or more programs designed to carry out operations for a specific application. Application software cannot run on itself but is dependent on system software to execute. Examples of application software include MS Word, MS Excel, a console game, a library management system, a spreadsheet system etc.
