Cards in this deck (8)
- 1What is meant by a 2GHz CPU?2GHz represents the clock speed of the CPU. This means that the CPU can preform 2 billion cycles per second.
- 2What is meant by a dual core processor?A dual core processor means that the processor has two processors inside of it. This allows it to preform tasks simultaneously.
- 3Describe the purpose of the RAM in the computer?The RAM of a computer store the programs that the person is currently using.
- 4Describe the purpose of the hard drive in the computer?The purpose of the hard drive is to save data. This data can then be accessed over and over again.
- 5Using examples, describe the difference between volatile and non-volatile memory?The RAM has volatile memory. This means that when the computer system is turned off, the memory will be deleted. Hard drives, on the other hand, have non-volatile memory. This means that the data is not deleted when the system is turned off.
- 6Explain two ways in which a computer can be upgraded to improve its performance?First of all, there would need to be more RAM in the system. This is because the more RAM in a computer system, the more programs it will be able to keep open. Another thing would be to get a CPU with a higher clock speed. This is because the higher the clock speed a CPU has, the greater the number of tasks that it can perform in a set amount of time.
- 7What is meant by a syntax error?A syntax error is when you don't follow the rules of the programming language.
print("hello world) This line of code has a missing speech mark. - 8Describe what is meant by a logic error?A logic error is when the code works but not as the user intends. This could be because the operators (AND, OR, NOT) or inequalities (<, >, <=, >=) are mixed up.
