Files are often compressed before they are sent over the internet. State what is meant by compression.
Compression is the process of encrypting a file to ensure data security during transmission.
Compression refers to converting a file into a different file format to make it compatible with various devices.
Compression is the act of dividing a file into multiple segments to facilitate faster transfer over the internet.
Compression refers to the process of reducing the size of a file or data to optimise storage space or download/upload speed.
Which of these is NOT a benefit of file compression.
Reduced File Size - Compressing files before sending them over the internet reduces their size, allowing for faster and more efficient transmission.
Faster Transfer Speeds - Compressed files require less bandwidth to transmit, resulting in faster upload and download speeds.
Storage Space Conservation - Compressed files occupy less storage space on the sender's and receiver's devices, allowing for more files to be stored.
Enhanced File Quality - Compressing files before sending them over the internet improves their overall quality and resolution.
When coding a game, which of these is NOT POSSIBLE when using a variable
Tracking Player Score - A variable can be used in game design to store and update the player's score throughout the game.
Changing Game Genres - A variable can be used in game design to switch the game's genre from a platformer to a racing game during gameplay.
Controlling Player Health - A variable can be used to keep track of the player's health, allowing it to be adjusted based on in-game events such as taking damage or gaining health points.
Managing Game Time - A variable can be used to keep track of the game's time, allowing for time-based events such as timed challenges or countdowns.

How does increasing the clock speed of a CPU generally impact its performance?
Increases the overall processing power by increasing the number of instructions that can be executed each second.
Enhances multitasking capabilities
Improves cache efficiency
Boosts the number of CPU cores
How does cache size affect CPU performance?
Larger cache size results in faster data retrieval
Smaller cache size improves multitasking capabilities
Cache size has no impact on CPU performance
Cache size influences clock speed of the CPU
How does the number of CPU cores affect performance?
Fewer cores result in faster clock speed
Additional cores increase cache size
