KB means, K means "thousand", 1024KB means 1 million, so it is represented by M, which is million, and 1024M, which is gigabit, is represented by GB, that is, gigabyte.
The storage medium that constitutes the memory is the storage element, which can store a binary code. A storage unit is composed of several storage units, and a memory is composed of many storage units. A memory contains many storage units, each of which can store one byte (byte-addressed).
Extended information:
The data (or instructions) of each unit does not change normally, but when another data (or or instruction), the original data (or instruction) disappears and new data (or instruction) is stored. When a piece of data (or instruction) is sent, the unit remains in its original state.
When a data (or instruction) is to be taken out or sent into the memory, the controller must first give a command, from the time the command is issued to the time the data (or instruction) is taken out or sent into the memory , it takes a period of time, this period of time is called the access time.
The storage capacity and access cycle of the memory are two important parameters. Memory is divided into internal memory and external memory. Internal memory is an integral part of an electronic computer, and external memory is an additional part of an electronic computer.
