Across
- 2. (9,6) required to make the computer work. It allows applications to communicate with hardware. It deals with opening and closing files, saving and deleting files. It controls how the computer uses resources (memory, input devices, output devices, storage devices).
- 6. (7) These are similar to database records and can store multiple different values E.g. firstname, surname, address, etc.
- 7. (15) This puts together files that have been split (fragmented).speeds up the process of reading from or writing to the hard drive as the read-write head does not have to move to several places.
- 9. (12,8)Everyday programs, e.g. Word processing, spreadsheets, accounting software, etc.
- 10. (8,9) A type of system software. Perform specific tasks E.g. Disk Defragmentation, File management, file compression, backup. These support the operating system. Some come with the operating system, some can be purchased separately.
- 11. (7,4,9) WIMP environment (Windows, Icons, Menus, Pointers) They use a lot of memory and processing power. It can be slower to use than a command-line interface if you are an expert user. They can be irritating to experienced users when simple tasks require a number of operations. They are much easier to use for beginners. They enable you to easily exchange information between software using cut and paste or 'drag and drop'.
- 12. (8,8) Protects the computer by stopping unwanted traffic entering the computer system, e.g. hackers or viruses. Incoming traffic is monitored and threats are prevented from entering the system. This filtering is based on a pre-determined set of security rules
- 14. (6) Software that controls the particular hardware that you have, e.g. printer Operating system comes with a set of drivers but for hardware that is new a new driver is required. This can usually be downloaded. Device drivers provide the communication link between the hardware and the operating system and translate the instructions and data into a format that can be handled by the hardware device.
- 15. (4,11) Reduces the size of files to reduce the storage space and to make file transfers quicker and easier
- 16. (4-10,8) used to produce reports, newsletters, etc.
Down
- 1. (4-5,8) This software is used to protect your computer system from malicious code.
- 3. (6,8) Controls the computer E.g. Operating system, User interface, Drivers
- 4. (4,10) The way that the user and computer interact is called the user interface. There are different types user interface: Command line, Menu driven and Graphical User Interface (GUI). Most users are used to GUI.
- 5. (7,4,9) Commands must be typed correctly and in the right order Difficult for inexperienced users because of the number of commands that have to be learnt. Very quick for experienced users. Do not need the memory and processing power of the latest computer and will often run on lower spec machines. Can run many programs, for example a batch file could launch half a dozen programs to do its task. Command driven programs do not need to run in Windows.
- 8. (6) These store multiple values, but of the same data typesE.g. If someone had taken 10 tests it could store the 10 results
- 12. (11,8) used to carry out calculations
- 13. (4,10) As well as using normal data types you can also use data structures when programming.These are again areas in memory to store data but contain more than a single variable.
