084f2db8c6 Unlike aGUIoperating system, a command line only uses akeyboardto navigate by entering commands and does not utilize amouse. First, they act as resource managers for the underlying hardware, allowing multiple users and applications to share resources such as CPUs, memories, peripheral devices, the network, and data of all kinds USER INTERFACE Character user interface CUIis another name for acommand line.Sometimes referred to as thecommand screenor atext interface, thecommand lineis auser interfacethat is navigated by typing commands prompts, as opposed to using the mouse to perform a command. For example, users who have Microsoft Windows may find trivial tasks such as renaming 100 files in afoldera very difficult task; however, this is something that can be done in a matter of seconds through a simple command at the command line. These directories may contain files and other directions. Linux,Unix,Windows OS are some example of multitasking operating system. Batch Operating System:-A batch system is one in which jobs are bundled together with the instructions necessary to allow them to be processed without intervention Multi-programming Operating System As machines with more and more memory became available, it was possible to extend the idea of multi-programming (or multiprocessing) as used in spooling batch systems to create systems that would load several jobs into memory at once and cycle through them in some order, working on each one for a specified period of time. Additionally, users do not need to know anyprogramming languages.
Allocates and de-allocates the device in the efficient way. De-allocates processor when processor is no longer required. The collective facilities are often known as file system. Programs responsible for this task is known as the I/O controller. Device Management OS manages device communication via their respective drivers. Decides which process gets the device when and for how much time. Because of their ease of use, GUI operating systems have become the dominant operating system todays end-users. There are different type of Multi-programming Operating System, some main stream are discussed below. Allocates the processor (CPU) to a process. packet) traffic and queues, controls access by multiple users to network resources such as files, and provides for certain administrative functions, including security.
