How is the memory size of a computer typically measured?

The memory size of a computer is typically measured in bytes. A byte is a fundamental unit of digital information storage, typically consisting of eight bits. Memory size is often expressed in larger units derived from bytes, such as kilobytes (1,024 bytes), megabytes (1,024 kilobytes), gigabytes (1,024 megabytes), and terabytes (1,024 gigabytes). This hierarchical structure allows for a concise representation of vast amounts of data and storage capacity.

While bits, gigabytes, and kilohertz may be related to computing, they pertain to different contexts. Bits are the smallest unit of data and are more often used in data transmission descriptions. Gigabytes refer to a larger measure of memory, yet the basic unit of measurement remains the byte. Kilohertz, on the other hand, measures frequency, not memory size, thus it is irrelevant in this context. By understanding that bytes serve as the core unit for measuring memory, it becomes clear why this is the correct choice.
