How does a GPU primarily differ from a CPU?
It has higher clock speed
It is designed for parallel processing of large datasets
It has fewer cores
It is used exclusively for data storage
What is the function of the Control Unit in a CPU?
Execute arithmetic operations
Store data temporarily
Manage the flow of instructions and data
Increase clock speed
What happens during the "Fetch" phase of the CPU instruction cycle?
Data is executed
Instructions are decoded
Instructions are retrieved from memory
Results are stored in memory
Which of the following correctly describes a dual-core processor?
It has two processing units capable of executing instructions simultaneously
It can only perform basic arithmetic operations
It has a higher clock speed than a quad-core
It is less efficient than a single-core processor
What does the term "overclocking" refer to?
Adding more cores to a CPU
Increasing the clock speed beyond the manufacturer's specifications
Reducing the CPU's power consumption
Installing additional RAM
In the context of the Von Neumann Architecture, what does the Program Counter (PC) do?
Stores data temporarily
Holds the address of the next instruction to be executed
Executes arithmetic operations
Manages input and output operations
A computer is running a complex simulation that requires intensive calculations. Which type of processor would be more effective for this task?
CPU
GPU
Both are equally effective
Neither can perform this task
During a software installation, the program is fetching instructions from memory. Which part of the CPU is responsible for this action?
Control Unit
ALU
Register
Cache
A user wants to improve their computer’s performance for gaming. They decide to overclock the CPU. What should they be cautious about?
It will decrease the number of cores
It may lead to overheating and potential damage
It guarantees better graphics
It will void the warranty
If a CPU has a high clock speed but only a single core, what might be a limitation in its performance?
It can process multiple instructions at once
It can only execute one instruction at a time
It will consume less power
It will have more cache
In a scenario where two numbers must be added, which registers are primarily involved in the fetch-execute cycle?
MAR and PC
MDR and ALU
PC and IR
MAR and MDR
A computer system is designed to handle multiple tasks simultaneously, such as video editing and gaming. What type of CPU configuration would be most beneficial?
Single-core
Dual-core
Quad-core or more
No cores
In a modern CPU, which component would be primarily responsible for executing complex calculations?
Control Unit
ALU
Cache
Registers
If a user notices that their CPU is running slower than expected, which of the following could be a potential reason?
The clock speed is too high
Insufficient cache memory
Too many cores
Overclocking has stabilized
During the instruction cycle, the CPU has just decoded an instruction. What is the next step?
Fetch the next instruction
Execute the decoded instruction
Store the instruction
Reset the program counter
In a scenario where a computer needs to process large amounts of graphical data quickly, which component would be most utilized?
CPU
Hard Drive
GPU
RAM
