An operating system has three main functions: (1) manage the computer's resources, such as the central processing unit, memory, disk drives, and printers, (2) establish a user interface, and (3) execute and provide services for applications software. ... Thus you both establish a user interface and execute software.

UNIX and LINUX isn't that hard to learn. As Kraelis said if you're proficient in DOS and command lines then you'll be just fine. You just have to remember some simple commands (ls, cd, cp, rm, mv, grep, vi, several others) and some of the switches for them.

Disadvantages of file processing. The file processing system is good when there is only a limited number of files and data in are very less. As the data and files in the system grow, handling them becomes difficult. ... Data Redundancy: – There are no methods to validate the insertion of duplicate data in the file system.

With the layered approach, the bottom layer is the hardware, while the highest layer is the user interface. The main advantage is simplicity of construction and debugging. The main difficulty is defining the various layers. The main disadvantage is that the OS tends to be less efficient than other implementations.

"Perhaps the major disadvantage is the processing and data overhead. There is processing overhead because as many as seven modules (OSI model) are invoked to move data from the application through the communications software. There is data overhead because of the appending of multiple headers to the data.

The main difference between UNIX and DOS is that DOS was originally designed for single-user systems, while UNIX was designed for systems with many users. ... Because UNIX and MS-DOS were developed at the same time they share some common syntax, and the UNIX neophyte will be happy to find many common commands and concepts.

“Linux is the most secure OS, as its source is open. Anyone can review it and make sure there are no bugs or back doors.” Wilkinson elaborates that “Linux and Unix-based operating systems have less exploitable security flaws known to the information security world.
