Answer
The laptop is equipped with a more powerful Intel Core i7 CPU, which allows for faster processing and better handling of tasks compared to the tablet's less powerful CPU.
The laptop has a larger storage capacity (1.5 TB HDD) than the tablet (32 GB SSD), making it more suitable for storing extensive data and files required for the competition.

Answer
Cache memory is a small-sized type of volatile memory that provides high-speed data access to the CPU. It stores frequently accessed data and instructions, allowing the CPU to retrieve them quickly, thus speeding up processing time. Cache memory functions by storing copies of the data from the main memory (RAM), reducing the time taken to access data.
