The size of RAM is one of the most important factors affecting overall computer performance. RAM serves as temporary storage for the data that the computer processes. The more RAM a computer has, the more tasks it can process simultaneously without slowing down. 8 GB of RAM is often considered the minimum for most tasks, while demanding applications such as games and professional graphic design or video editing software may require 16 GB of RAM or more.

The type of storage in a laptop can have a significant impact on its performance and price. The two most common types are Hard Disk Drive (HDD) and Solid State Drive (SSD). HDD is an older technology with moving parts and provides a large amount of storage space at a low cost. SSDs are faster, quieter and more reliable, but generally more expensive.

The capacity (size) of the hard disk determines how much data the disc can accommodate.
