A byte is a unit that computers use to represent a character such as a letter, number, or a typographic symbol (for example, “h”, “7”, or “$”). In computer systems, a unit of data that is eight binary digits long is known as a byte.

“12800 KB RAM” refers to the amount of main memory the computer provides to its CPU whereas “128 MB disk” symbolizes the amount of space that is available for the storage of files, data, and other types of permanent information. But it’s important not to confuse between these two. 1024 3 bytes), the difference between the base two and base ten amounts is almost 71 MegaByte.īoth computer memory and disk space are measured in these units. A kilobyte is not exactly, as one might expect, of 1000 bytes. In practice, memory is measured in KiloBytes (KB) or MegaBytes (MB). The computer represents all characters and numbers internally in the same fashion. Of course, these bytes may also be combined to represent larger numbers. 1 byte can represent numbers between zero (00000000) and 255 (11111111), or 2 8 = 256 distinct positions. A group of eight bits is known as a byte. In order to count higher than 1, such bits (BInary digiTS) are suspended together. These two states in terms of memory are represented by a 0 or 1. Data is lost in case power is switched off.Ī computer processor is made up of multiple decisive circuits, each one of which may be either OFF or ON.It is the working memory of the computer.A computer cannot run without the primary memory.General purpose registers in 8086 microprocessor.Memory Segmentation in 8086 Microprocessor.Addressing modes in 8086 microprocessor.Addressing modes in 8085 microprocessor.
