Edexcel GCSE Computer Science Topic 3: Computers

What is the role of main memory in the von Neumann stored program concept?

• Management of peripheral devices

• Temporary storage of data and instructions

• Execution of arithmetic operations

• Long-term storage of data

Which of the following is an example of secondary storage device?

• SSD

• Cache memory

• RAM

• Registers

What are embedded systems used for?

• Executing complex algorithms

• Managing network connections

• Controlling specific functions in electronic devices

• Running operating systems

What is the purpose of file management in an operating system?

• Optimizing CPU performance

• Executing application software

• Organizing and controlling data on storage devices

• Managing user accounts

Which of the following is a functionality of utility software?

• Data encryption

• Network security

• Disc defragmentation

• Memory management

What is the importance of developing robust software?

• Optimizing network speed

• Preventing system crashes

• Improving user interface design

• Enhancing hardware performance

What are the characteristics of high-level programming languages?

• Limited functionality

• Platform independent

• Close to machine code

• Directly executable by the CPU

How does an interpreter differ from a compiler?

• Translates the entire code and then executes it

• Translates code line by line and executes it immediately

• Converts high-level code to low-level code

• Optimizes the code for better performance

What is the purpose of clock in the fetch-decode-execute cycle?

• Controls the flow of data between CPU and memory

• Manages the execution of processes

• Stores the address of the next instruction

• Synchronizes the operations of the CPU

Which of the following is a characteristic of low-level programming languages?

• Platform independent

• Easy to learn and use

• Close to machine code

• High level of abstraction
