Being a good server administrator means that you understand your systems from the ground up â both the software and the hardware. Today's server hardware is sophisticated and specialized to support multiple users, applications and processors, as well as provide fault tolerant, highly available services. This course begins the look at server hardware architecture, starting with server system boards, chassis, memory, and the brain of the server â the CPU. The course also describes the various types of expansion cards and the supporting architectures and explains when...
Overview/Description
To take full advantage of expensive server hardware, a full featured network operating system (NOS) should be employed. Network operating systems provide vital services, such as e-mail, file sharing, DHCP, DNS, and other necessary components of a functional enterprise network. This course covers the different types of network operating systems, including Windows NOS and UNIX/Linux flavors. It also describes the basic and advanced configurations to make the NOS useable. One of the most important aspects of NOS software â security â is also covered in this course along...

As an inherently multi-user system, Linux requires a way to manage disk usage by different users, and does so through quotas. Linux file system security is managed though user and group permissions and ownership. Files in Linux can be linked in a flexible way through the use of hard and symbolic links. This course covers quotas and file level security, and the use of links and the locations of system files and other important file locations. This course is part of a series that prepares the learner for CompTIA Linux+ exam LX0-101 and Linux Professional Institute (LPI)...
