- - - - A debugger or debugging tool is a computer program used to test and debug other programs.
    - - A translator converts assembly language into machine code
    - - A compiler is used to translate source code into machine code, It does this in one go
    - - An integrated development environment is a software application that provides comprehensive facilities to computer programmers for software development.
  - - - Project management software has the capacity to help plan, organize, and manage resource tools and develop resource estimates.
    - - Computer-aided design & computer-aided manufacturing (CAD/CAM) software is used to design and manufacture prototypes, finished products, and production runs of products.
    - - A Management Information System is an information system used for decision-making, and for the coordination, control, analysis, and visualization of information in an organization
    - - An expert system is a computer system emulating the decision-making ability of a human expert
  - - - A spreadsheet is a computer application for organization, analysis and storage of data in tabular form.
    - - A database is an organized collection of data, generally stored and accessed electronically from a computer system
    - - A word processor is a device or computer program that provides for input, editing, formatting and output of text, often with some additional features
    - - Email is a way of sending electronic messages over the internet
- - - - It mans that any file on a computer that gets damaged can't be lost completely because there is a version of that file has been backed up
    - - Full backups copy every file on the system every time you back up meaning you could have lots of the same version of a file.
    - - Full backups copy everything on that is on the server.
    - - Incremental backups only back up documents that have been changed since the last backup was done.
  - - - Lossless compression reduces the size of the file without losing data.
    - - Is that it can save space by making files smaller.
    - - Lossy compression removes data in order to make the file size smaller
    - - Lossy compression removes some of the data to reduce the size of the file.
- - - - A multiprocessor is more complicated as the processor must work in time with one another
    - - A single processor only needs to do one task on its own
  - - - Is widely available and comes ready to use. There is normally a licence fee to pay to use their operating system.
      - Windows
      - Comes with lots of features that might not be used
    - - is custom made for that Buissness and will only have features that will be used.
      - Is very expensive
    - - Open source software is where the code is available to the public meaning anyone can edit the code. This leads to their being many different operating systems using the same code
      - Linux
      - Could be contain malicious software
- - - - Baseline testing refers to the validation of the documents and specifications on which test cases are designed. Base line refers to a benchmark that forms the base of any new creation.
    - - A virus scanner checks whether malware is being run in the background and slowing down the system.
    - - Examine the traffic between computers for errors. The system not only identifies current issues but also provides a set of benchmarks once the system is set up and stable.
    - - Keeping a fault log is incredibly important for users as it shows how the fault occurred, where it occurred, and what it is. If you have a fault you can refer back to the fault log and quickly find out how to solve the issue efficiently.
    - - Data is not sent as a single stream across the internet but instead it is parcelled into one or more packets, each of which das a header with additional information such as the IP address of the sender and the receiver
