Linux is a free and open source operating system developed by linus torvalds and came into existence in the year 1991, at at & t’s bell laboratories, released under the gpl (general public license. Some operating systems allow all user programs to directly play with the hardware components (a typical example is ms-dos) in contrast, a unix-like operating system hides all low-level details concerning the physical organization of the computer from applications run by the user.
Input devices are hardware devices which take information from the user of the computer system, convert it into electrical signals and transmit it to the processor. Types of user interface: many computer or database operating systems use complex programming languages which are not easy to use a user interface is created to allow easier control of the operating system by the user of the system. -4-was achieved by increasing the amount of the operating system that could be swapped dos 33, released in 1987, provided support for.
Software system components a computer system consists of three major components: hardware, software, and humans (users, programmers, administrators, operators, etc) software can be further divided into seven layers firmware can be categorized as part of hardware, part of software, or both. Structure however, many modern operating systems share the system components outlined below 131 process management the cpu executes a large number of programs while its main concern is the execution of user programs, the cpu is also needed for other system activities these activities are called processes a process. With a command-line operating system (eg, dos), you type a text command and the computer responds according to that command with a graphical user interface (gui) operating system (eg, windows), you interact with the computer through a graphical interface with pictures and buttons by using the mouse and keyboard. It allows the end user to communicate with the operating system so they can load programs, access files, and accomplish other tasks the three main types of user interfaces are: the three main types of user interfaces are. A multi-user operating system has been designed for more than one user to access the computer at the same or different time types single user, single task: a single task is performed by one user at a time example- the palm os for palm handheld computers.
