- 1which is an example of a IP address?192.168.2.1
- 2Which part of the CPU will send signals to the memory, ALU and the input/output devices?Control Unit
- 3Which of the following statements best describes a constant?A constant is a named value which can't change when the program is running.
- 4Which of the following would NOT be covered by a good network policy?Upgrading the hardware and software on a regular basis to maintain the best network performance.
- 5Increasing your RAM will result inMore programs able to be loaded at the same time.
- 6Which register which holds the actual data or instruction about to be used by the CPU?Memory data register (MDR)
- 7What is decomposition?Breaking a complex problem down into smaller problems and solving each one individually.
- 8Which of the following statements best describes an algorithm?An algorithm is a logical step-by-step process for solving a problem.
- 9Why do we use abstraction?To reduce complexity to make it more efficient to implement.
- 10What is the main reason why a good network policy will enforce user access levels?To limit the number of people who can access sensitive information.
- 11In the CPU, this is a register which holds the memory address of the instruction for each cycle.Program counter
