Software (Two types of software (Application software (Examples (Database,…

- - - - Backup
        
        Backup utilities create a copy of files and programs just in case they get corrupted or deleted
      - Defragmentation
        
        Fragmentation utilities software gathers data from the same file/app and stores it in order to make it easier for the hard drive to access the information
      - Compression
        
        Compression utilities reduces the original size of a file or set of files. This can be useful wen uploading or/and downloading documents.
      - Formatting
        
        Disk formatting utilities prepare storage media such as a hard disk, drive or USB Flash drive for its first use. This is used to destoy data
      - Extraction
        
        Extraction utilities are used with compressed files to turn them into the original files. This is because compressed files cannot be launched.
      - What is it?
        
        Is one form of system software, which carries out configuration and maintenance tasks
    - - Print spooling
        
        During large print jobs, the computer will have the pages ready for the printer faster than the printer can produce them. The operating system keeps each page in a queue ready for printing. this process is called print spooling
      - Security
        
        operating systems can give users secure access to a computer's storage and other hardware through usernames and passwords, biometric scanning or personal access cards. this process is called authentication. Operating systems can provide software firewalls to authorize or prevent network data from remotely accessing a service or application
      - Resource management
        
        System resources include internal components such as the processor and graphics card, and external devices, such as printers. As well as allocating memory, the operating system ensures that system resources are made available to applications when they are required. If a system resource is already being used by another application, then the operating system may say that the required resource is in use and place the additional request in a queue. For some resources such as printers , the operating system can tell the user when the resource becomes available
      - Memory management
        
        Memory management utilities allocate the required amount of memory (RAM) to one or more applications. When the application no longer requires the memory space, the operating system makes the space available for other applications to use
      - What is it?
        
        the operating system (OS) allows the user to control and manage the computer's hardware
  - - - Word processing
        
        Lets users create documents that mostly include words, but also some images. They can also include tables, hyperlinks, equations, simple drawings, shapes, and charts. An example of word processing software is Writer from the LibreOffice application suite.
        
        Some allow people to work together on a document. Comments can be added to the text so that others can understand the writer's intention and give feedback. The software can also track any changes made to the document, giving others the option to accept and reject those changes.
        
        When do we use it?
        
        when righting down documents
      - Desktop publishing
        
        when do we use it?
        
        It is very similar to the word processing software. The main difference is the way which the software allows users to work with complicated page layouts. An example of DTP software is adobe InDesign
      - Spreadsheet
        
        when do we use it?
        
        when righting down calculations.
        
        User can use and create formula and unctions to perform automatic calculations on values that can be entered and changed later. There, features allow spreadsheets to be used to model financial scenarios and answer 'what if?' questions.
      - Database
        
        when do we use it?
        
        to enter edit and search data of any kind
        
        Some systems can also produce reports that dynamically display real time changes to the data as it updates
        
        DBMS software features include:
        
        Data entry forms so that users can input data
        
        Query editors so that users can select all data that meets certain criteria
        
        Report builders so that users can display data in a more readable format
        
        An example of DBMS software is Oracle My SQL.
      - web authoring
        
        When do we use it?
        
        We use it to create web pages that include text and images. The pages are output as Hypertext Markup Language (HTML)
        
        There are web authoring software such as Dreamweaver that are called WYSIWYG "What You See Is What You Get", because the published page will look very similar to the page the user edits in the web authoring software. These are editors that people with little or no HTML experience can use in order to create there own HTML code.
        
        HTML code is read and displayed by web browsers such as Google Chrome, Microsoft edge or Mozilla Firefox. Another good example would be the browser you are using right now.
      - Image editing
        
        Graphics editors
        
        When do we use it?

        Resizing, aligning or moving shapes and lines
        
        Vectorising images (That is, converting or tracing bitmap graphics to vector graphics)
        
        Altering the colour of shapes, lines and fill areas

    - - Apps are usually downloaded from servers on the internet. Some devises, like smartphones and tablets, operating systems that provide access to app stores. Some of these only make apps available to users after the store has checked the quality of the app and has ensured that the app does not include storage media like DVDs.
    - - Software applications (apps) allow users to produce a digital product, such as a presentation or image, or carry out specific tasks that are not related to the operating system.
