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

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.

Processor frequency, often referred to as clock speed, is a key indicator of processor performance. It is measured in gigahertz (GHz) and represents how many operations a processor can perform per second. Higher frequency generally means higher performance, but it can also lead to higher power consumption. It is important to find the right balance between performance and efficiency for your specific needs.
