Final answer:
The statement is true that the main memory of a computer is referred to as RAM, which is a type of memory allowing the processor to access data directly and quickly.
Step-by-step explanation:
The statement that the main memory of a computer is also called random access memory (RAM) is true. RAM is a crucial component in computers and other devices, as it is where the processor can quickly access the data and applications that are in active use. Unlike other types of storage that may require sequential access, RAM allows the processor to access any part of the memory directly and at any time, hence the name 'random access.'
Main memory is essential for a computer's performance because it provides the space for the operating system, applications, and ongoing processes to load and execute. The more RAM a computer has, the more information it can handle simultaneously, which can result in faster system performance.
