Unformatted text preview: represented in binary form. In fact, all information is somehow represented using binary values. The reason is that each storage location within a computer either contains a low-voltage signal or a high-voltage signal. Because each location can have one of two states, it is logical to equate those states to 0 and 1. A low-voltage signal is equated with a 0, and a high-voltage signal is equated with a 1. In fact, you can forget about voltages and think of each storage location as containing either a 0 or a 1. Note that a storage location cannot be empty: It must contain either a 0 or a 1. Each storage unit is called a binary digit or bit for short. Bits are grouped together into bytes (8 bits), and bytes are grouped together into units called words . The number of bits in a word is known as the word length of the computer. For example, IBM 370 architecture in the late...
