The document discusses the information processing cycle which consists of 4 steps: (1) input - entering data into the computer using devices like keyboards, mice, and scanners, (2) processing - performing operations on the data using the central processing unit (CPU) which interprets instructions and processes data, (3) output - displaying or producing the processed data, and (4) storage - saving the processed data in the computer's memory. The CPU, which can be a microprocessor, is the key component that executes programs and provides computers with their programmability.

processing cycle?
The sequence of events in processing
information, which includes
• (1) input
• (2) processing
• (3) output
• (4) storage

• CPU Processor - Central Processing Unit
• A central processing unit (CPU), or sometimes simply
processor, is the key component in a digital computer capable
of executing a program. It interprets computer program
instructions and processes data. CPUs provide the
fundamental digital computer trait of programmability, and are
one of the necessary components found in computers of any
era, along with memory and input/output facilities. A CPU that
is manufactured as a single integrated circuit is usually known
as a microprocessor. Beginning in the mid-1970s,
microprocessors of ever-increasing complexity and power
gradually supplanted other designs, and today the term "CPU"
is usually applied to some type of microprocessor.
