UNIX is an operating system. It is a stable, multi-user, multi-tasking system for servers, desktops and laptops.
UNIX systems also have a graphical user interface (GUI) similar to Microsoft Windows which provides an easy to use environment. However, knowledge of UNIX is required for operations which aren't covered by a graphical program, or for when there is no windows interface available, for example, in a telnet session.
This course gives coverage in following areas
1. Memory Command
2. Network Command
3. System Management
4. Process Management
5. Compress Files & Folders
6. Record Scrips
