Study Notes

Computing

Computing is a powerful intellectual tool, impacting various aspects of human culture.
Tools have amplified physical abilities, but intellectual ability enhancers are rare.
Language and writing were early amplifiers of intellectual abilities.
Computing acts as the ultimate mental amplifier, automating intellectual activities.
Computing has profoundly altered the world, impacting nearly all human endeavors.
Key reasons to study computing:
- Nearly all current and future technologies, arts, and sciences rely on computing.
- Studying computing provides insights into human minds, culture, and the universe.

Processes, Procedures, and Computers

Computer science studies information processes.
A process is a sequence of steps that change the world's state, leading to a goal state.
Examples of processes: baking a cake, mailing a letter, or planting a tree.
Processes involving abstract information are a focus of computer science.
A procedure describes a process by listing steps.
An algorithm is a mechanical procedure guaranteeing completion.
Procedures involve mechanical steps without needing thought.

Measuring Computing Power

Information is measured by the change in uncertainty.
A bit is the basic unit of information, reducing uncertainty by half.
A binary question (yes/no) yields one bit of information.
A six-sided die provides more than one bit of information.
Multiple bits can distinguish a greater number of values.
A series of questions can identify a specific value from a set.
Bits can efficiently distinguish among many values.
Computing power can be measured by processing speed and information storage.

Representing Data

Data, including text and images, can be represented using bits.
Text sequences can be converted to unique numbers, represented efficiently.
Characters can be represented by specific bit sequences.
Sequences of bits are used to represent various forms of data, like numbers and text.
Bit sequences in various lengths and complexities can represent texts and images.
Representing images often involves splitting them into smaller squares (pixels), each with a color value encoded in bits.
