When upgrading memory, which component of the computer is typically replaced?

When upgrading memory, the component of the computer that is typically replaced is RAM, or Random Access Memory. RAM is a type of volatile memory that temporarily stores data that the CPU needs to access quickly while the computer is running.

Upgrading RAM is a common way to enhance a computer's performance because it allows for more applications to run simultaneously and provides more memory space for data that the CPU can quickly access, leading to improved overall efficiency.

The other components mentioned, such as the CPU, hard drive, and motherboard, serve different roles in the computer system. The CPU, or Central Processing Unit, is responsible for executing instructions and performing calculations. The hard drive, which can be either a traditional HDD or a solid-state drive (SSD), is used for long-term data storage. The motherboard connects all these components but is not specifically connected to memory upgrades in terms of daily operations and performance enhancements. Therefore, when discussing memory upgrades specifically, RAM is the correct answer.
