- - - - The command line interface is an interface the user needs in order to have different commands regarding the input and output and then a task is preformed this is called the command line argument.
        
        Gui stands for graphical user interface some of the desktop interfaces are windows menus etc, wimp is a commonly used acronym in traditional Guis .
        
        The command line interface are entered into the computer it requires very little processing and can save on the need for an expensive graphics card for expert users who know commands its a lot faster to enter commands.
        
        Voice activation is to do with like Siri and can be used to send voice messages to friends or family which can be useful however it can have some disadvantages where it may not send the message you want it to send.
        
        Menu driven interface are often used by devices that have a dedicated function including a mp3 players ATM machines self service checkouts.
  - - - Memory management is a crucial function of an operating system that handles the allocation and deallocation of memory spaces to various processes. It ensures efficient utilization of memory, maintains data integrity, and
      - minimizes fragmentation issues.
      - When the ram is full the app that you are using the least will be placed in the virtual memory but when you want to use it again it will be changed with the one you have interacted with the least recently .
      - Virtual memory is where all the apps are placed when the ram is full and not used anymore. And then when you want to use it again and it will replace instead of a map your not using.
  - - - A multitasking operating system allows multiple tasks or processes to run simultaneously on a computer, enhancing efficiency and user experience. Unlike single-tasking systems, which can only handle one task at a time, multitasking systems enable users to perform various activities concurrently, such as downloading files, browsing the internet, and listening to music
        Multi tasking is where you are using many different apps at once for example listening to music as well as working on homework can be multi tasking the. The device will use the 2 different apps at different times although it may seem that it is both being used at once however if you have 3 different apps open it would go ABC and if you was finished with c app it would go ababababab until you are finished with the applications
  - - - File managements is he process of organising storing and retrieving digital files
      - Creating logical structures and systems to facilitate easy categorization searching and retrieval of files
      - Controlling data files stored on could or device .
      - Disk management is an extension of Microsoft that allows full management of the disk based hardware recognised by windows
      - Its used to manage the drives installed in a computer like hard drives internal and external optical disk drives, and flash drives it can be used to partition and format drives assign drives letters , and much more.
      - You can rename open copy move save search for and sort and delete files.
- - - - Encryption software is a type of software that prevents unauthorized access to information cryptography is the practice of securing information by transforming it into a unreadable format which can only be converted back into its original from by someone who posses the correct decryption key .
        One type of encryption software would be symmetric key ciphers these use the same key for both encryption and decryption they are efficient and commonly used for encrypting data at rest examples include aes ( advanced encryption standard) and des ( data encryption standard ) .
    - - Defragmentation software also known as a defragmenter addresses this issue by consolidating fragmented data and organizing it into contiguous regions this process reduces the amount of movement required by the read write heads they improve the overall performance of the storage device
        
        Defragmentation works by analysing the disk and moving the data across then compacting it;.
        
        Benefits of defragmentation is improving the performance increasing the lifespan the efficient software is caused by optimizing the disks space by consolidating fragmented files and freezing up contiguous blocks of space.
    - - Data compression is the process of encoding information using fewer bits than the original representation it aims to reduce the size of the data files enhancing the storage efficiency and speeding up data transmission compression can be either lossless or lossy.
      - examples
        
        all examples
        
        WinRAR (Windows)
        
        MacRAR (macOS)
        
        PeaZip (supports more than 150 file formats)
        
        7-Zip (open-source)
        
        Bandizip
        
        Express Zip
        
        Ashampoo Zip Free
  - - - Disk clean-up tools are utilities designed to remove unnecessary files from a computer's hard drive, freeing up storage space and potentially improving system performance. These tools scan for temporary files, system files, and other data that can be safely deleted without impacting the operating system.
        
        Types of files removed:
        
        Temporary files: Files created by applications or the operating system that are no longer needed.
        
        System files: Files related to the operating system that are not essential for its functioning.
        
        Recycle Bin contents: Deleted files that are still stored in the Recycle Bin.
    - - Disk formatting is the process of preparing a data storage device such as a hard disk drive, solid-state drive, floppy disk, memory card or USB flash drive for initial use. In some cases, the formatting operation may also create one or more new file systems.
        
        File Systems: Common file systems used for formatting include FAT32, NTFS, exFAT, and EXT4.
        
        Formatting Tools: You can use various tools to format disks, such as Disk Genius, Windows built-in formatting utility, and Disk Part.
        
        Purpose of Formatting: Disk formatting is typically done to prepare a storage device for initial use, clean the disk, or free up space.
- - - - Proprietary software, also known as closed-source software, refers to software that is owned by an individual, company, or organization. The source code of proprietary software is not made available to the public, making it impossible for users to modify, distribute, or study the code.
      - examples
        
        Microsoft windows etc.
  - - - Open Source Software (OSS) refers to software that is released with a license that allows users to freely use, modify, and distribute the software and its source code. This means that anyone can inspect, enhance, and share the software, fostering a collaborative and transparent development environment
