CPU And System Performance Flashcards
(15 cards)
What are the main hardware components that affect computer system performance?
CPU, RAM, GPU
These components significantly influence the speed and efficiency of a computer.
What is clock speed?
The number of instructions a single processor core can carry out per second (Hz)
For most desktop computers, clock speed is typically around 3.5 GHz.
How does increasing clock speed affect CPU performance?
It allows the CPU to carry out more instructions per second
Higher clock speeds lead to better performance but may require cooling systems when overclocked.
What is the risk associated with overclocking a CPU?
It can cause overheating, crashes, or permanent damage
Proper cooling systems are essential for safe overclocking.
What is the significance of the number of cores in a CPU?
More cores allow for more instructions to be processed simultaneously
However, performance gains depend on software being designed for multicore processing.
What is cache size in relation to CPU performance?
Cache is a faster data storage inside the CPU than RAM
A larger cache enables quicker access to data needed for processing.
What effect does having more RAM have on system performance?
It allows for smoother operation of more applications or memory-intensive applications
Insufficient RAM may lead to slower performance due to reliance on virtual memory.
How can RAM be upgraded in a PC or laptop?
By replacing the RAM sticks with higher capacity or higher speed ones
Upgrading RAM is generally straightforward.
What role do GPUs play in a computer system?
They handle graphics and image processing, relieving the CPU’s processing load
This allows the CPU to focus on other tasks.
What are the two types of GPUs mentioned?
Integrated GPUs and dedicated GPUs
Integrated GPUs are built into the motherboard or CPU, while dedicated GPUs are separate graphics cards.
True or False: Using a high-end graphics card can improve performance in graphics-intensive applications.
True
High-end graphics cards enhance performance in activities like gaming and design software.
Fill in the blank: The CPU cache is faster than _______.
RAM
Faster access to data is crucial for efficient CPU performance.
What is the typical number of cores found in most modern PCs and smartphones?
4 or more cores
More cores help in handling multiple tasks effectively.
What is the impact of having too little RAM on a computer’s performance?
It may run slowly due to the use of virtual memory
Virtual memory uses disk space as an extension of RAM, which is slower.
What is the function of PCI interface slots on a motherboard?
They allow for the installation of dedicated GPUs and other expansion cards
PCI slots provide flexibility for upgrading system components.
