Example 3

medium
A school is buying new computers. Explain why upgrading the RAM and switching from hard drives to SSDs would improve performance. What type of component is each (hardware or software)?

Solution

  1. 1
    Step 1: RAM (hardware) stores data currently in use. More RAM means more programs/data can be active simultaneously without slowing down. An SSD (hardware) reads/writes data much faster than a traditional hard drive.
  2. 2
    Step 2: Both are hardware upgrades. No software changes are needed. However, the existing software (operating system, applications) will run faster because it can access data more quickly.

Answer

Both are hardware. More RAM = more active programs. SSD = faster data access. Software runs faster on better hardware without any code changes.
Understanding which hardware components affect which aspects of performance helps in making informed purchasing decisions. RAM affects multitasking; storage speed affects loading times.

About Hardware & Software

Hardware is the physical components of a computer (processor, memory, storage, peripherals) that you can touch. Software is the set of instructions (programs) that tell hardware what to do. Together they form a complete computing system—hardware provides the capability, and software provides the purpose.
