CENTRAL PROCESSING UNITThe logical atomic element for all digital computers is the binary digit or bit . Each bit can assume one of two values: 0 or 1.
Groups of bits and bytes can represent not only decimal integers but also fractional numbers, general characters (upper-case and lower-case letters, digits, and punctuation marks), instructions to the CPU, and more complex data types such as pictures, spoken language, and the content of a medical record.
P.S.: 1 byte is made up of 8 bits

Which best describes relatively inexpensive, single-
user machines?
a. Personal computer (PC)b. Workstation
c. Server d. Magnetic disks
Which best describes relatively inexpensive, single-
user machines?
a. Personal computer (PC)b. Workstation
c. Server d. Magnetic disks
REMEMBER!
Workstations are also single-user machines but are more powerful,
targeted to specific tasks and thus more expensive than PCs
