Correct Answer:
B. More programs can run simultaneously
Upgrading a computer's RAM from 4 GB to 8 GB primarily benefits the system by allowing more programs to run simultaneously. RAM acts as a computer's short-term working memory, holding data and applications currently in use. With more RAM, the operating system has a larger temporary workspace, reducing the need to swap data to slower storage (like the hard drive). This significantly improves multitasking capabilities and overall system responsiveness when many applications are open.
- A: Faster processor speed is achieved by upgrading the CPU, not RAM.
- C: Larger files can be stored permanently is the function of permanent storage devices like HDDs or SSDs, not volatile RAM.
- D: Faster internet browsing is primarily dependent on internet connection speed and browser efficiency, not directly on RAM capacity.
