Question

Quizplus · Accepted Answer

The 2 GB specifies the amount of RAM (Random Access Memory) in the computer system. RAM is the temporary memory used by the computer to store and access data and programs quickly while they are in use. The type of RAM in this particular computer is DDR2 SDRAM (Double Data Rate 2 Synchronous Dynamic Random Access Memory) and it operates at a speed of 800 MHz. The "Dual Channel" means that the computer has two identical RAM channels, which can increase the overall memory bandwidth. The "max 4 GB" specification means that the computer can support up to 4 GB of RAM if additional memory is added.
