What is Computing?

A goal-oriented activity involving the creation and use of computers.
It encompasses various aspects, including:
- Designing and constructing hardware and software systems.
- Processing, structuring, and managing information.
- Problem-solving.
- Making computer systems behave intelligently.
- Creating and using communication and entertainment media.
- Finding and gathering information.

History and Evolution of Computing

Ancient Times: Abacus (circa 3000 BCE).
17th – 19th Century: Mechanical Calculators.
1837: Babbage's Analytical Engine, a foundational concept for modern computers.
Late 19th Century: Hollerith's Tabulating Machine, which used punch cards to process data.

What is a Computer?

A computer is a device that processes data.
It performs four major functions: input, process, output, and storage.
Data is a representation of a fact, figure, or idea.
Information is organized and presented data that is meaningful to humans.

### Data Representation

Computers represent data electrically.
All data is translated into binary, a series of 0s and 1s.
Each 0 or 1 is a bit.
Four bits combine to form a nibble.
Eight bits combine to form a byte.

Binary

Kilobyte = 1024 bytes
Megabyte = 1,048,576 bytes
Gigabyte = 1,073,741,824 bytes
Terabyte = 1,099,511,627,776 bytes

Computer Components

A computer system uses hardware and software.
Hardware is the physical parts of a computer.
Software are sets of procedures that enable the hardware to perform tasks.

Computer Hardware

A computer's hardware consists of a processor, storage, input/output devices.
The processor, or CPU, manipulates and transforms data.
Storage holds data and programs.
Primary storage holds data and programs needed immediately and is temporary.
Secondary storage holds data and programs for long-term use and is permanent.
Input/Output devices or peripherals enable communication with humans and other computers.
Input devices accept input from humans and convert it into a form the computer can understand.
Output devices convert signals from the computer into a form humans can understand.

Computer Software

Software translates human languages into binary computer languages.
Application software performs specific tasks for the user.
