Types of Memory (continued)
RAM (random access memory) is a temporary holding area for both data and instructions. It is also referred to as main memory.
Data in RAM is lost when the computer is turned off.
Measured by its memory capacity and latency.
Capacity is the maximum number of bits or bytes that can be stored. The capacity of RAM is typically measured in megabytes (MB). Many computers have RAM capacity of 128MB or more.
Latency is the delay between the time when the memory device receives an address and the time when the first bit of data is available from the memory device. This delay is also referred to as access time. Latency is typically measured in nanoseconds (ns), billionth of a second (10-9 sec). Latency measures the speed of RAM.
