File Management Definition
Process carried out by operating system creating, organising and accessing files and folders on a computer system.
Interrupt Handling Definition
Interrupt events require the immediate attention of the central processing unit the OS manages it, so it is handled in a timely manner.
User Interface Definition
A user interface is how the user interacts with the operating system.
Peripheral Management Definition
Process carried out by OS managing the way peripherals (Hardware) interact with the software.
Device Driver Definition
Piece of software used to control a piece of hardware, peripherals (Hardware) require device drivers in order to be used by the operating system.
Memory Management Definition
Process carried out by OS allocating the main memory between different programs that are open at the same time.
Multitasking Definition
Process made possible by OS simultaneously managing system resources to give the user the perception of being able to us multiple programs at the same time.
Providing a Platform For Running Applications Definition
Operating systems provide a platform on which application software can run, this is mainly by allowing software to access system resources.
System Security Definition
OS provides various security features such as: Password-Protected System Accounts, A Firewall, Virus Scanning and File Encryption.
User Management Definition
Is a process carried out by the OS enabling different users to log onto a computer maintaining their individual settings and access levels.
What is an example of File Management?
Naming files (unique file names and extensions, e.g. report.docx).
Storing files in folders/directories.
Retrieving files when a program/user needs them.
Managing permissions (who can read/write/delete).
Preventing conflicts (e.g. two programs accessing the same file).
What is an example of Interrupt Handling
You are typing on a keyboard.
Each keypress sends an interrupt to the CPU.
The CPU stops its current task and runs the ISR to register which key was pressed.
Then the CPU goes back to its previous job (e.g., running your word processor).
What is an example of User Interface
NLI (Natural Language Interface)
GUI (Graphical User Interface)
CLI (Command Line Interface)
Menu Interface
What is an example of Peripheral Management
Transmits data to hardware, Allocates data to buffers
What is an example of Device Drivers
Printer driver, keyboard driver and mouse driver
What is an example of Memory Management
Operating system allocates memory to processes
What is an example of Platform For Running Applications
Allows applications to run on a computer
