• What are the types of computer systems?

  Quantum, Desktop, Mainframe, Smartphones, Embedded system, tablet and laptop
• What is a mainframe computer system?

  They are huge powerful computers that are used to process large amounts of data which can be usede to solve complex calculations with large datasets
• Explain why Mainframes are reliable and secure?

• Give the downside of Mainframes?

  They are expensive and it requires IT experts to oversee them, so they are only used by organisations that needs to process large amounts of data such as Banks.
• What is a Quantum computer?

  They are powerful computers which uses quantum mechanics to perform complex calculations.
• What do quantum cpmputers work with and what do they represent?

  They work with quantum bits (Qubits) and they represent atomic particles which can be used in different states at the same time.
• Explain a fully functional quantum computer?

  It can present data and perform calculations way faster than current available computers.
• What is a desktop computer?

  Its a type of computer system thats suitable at an ordinary desk
• Explain the disadvantages of desktop computers?

  They are bulky and not easy to move.
• Explain some factors about desktop computers?

  Individual components such ass Graphics card can be upgraded over time. They are versatile as they allow the user to carry a range of activities.
• What is an embedded system?

  It is when a smaller computer system is installed to a larger device such as washing machines.
• Give the important feature of a tablet or laptop?

  A portable type of system.
• Give the benefits of tablets and laptops?

  Many modern laptops can bold back, which turns them into a tablet with a screen based virtual keyboard
• Give the disadvantage of tablets and laptops?
