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

Within an information system why Feedback is important?
To improve processes, to improve data usage and storage, improve the system as a
whole, to find new better solutions etc…

REMEMBER!
Workstations are also single-user machines but are more powerful,
targeted to specific tasks and thus more expensive than PCs
