Computer Basics and Operations

Study Notes

Computer Operations

Computers receive data in various formats based on application type.
Data processing involves three key steps: capturing input, manipulating data, and generating output.
These steps are illustrated in Figure 1.1, although the figure isn't provided here.

Computer Characteristics

Computers work automatically without human intervention.
They boast incredible speed, processing in microseconds, nanoseconds, or even picoseconds.
Powerful systems achieve billions of arithmetic operations per second.
Accuracy is high if input data is correct, leading to near-perfect precision.
Computers exhibit unwavering diligence, working continuously for days without fatigue.
Unlike humans, they don't experience boredom or tiredness.

Basics of Computers

Computers are versatile, capable of performing multiple tasks simultaneously.
They can store large amounts of data for future access and retention.
Computers lack intelligence, unable to think or make independent decisions.
They rely solely on programmed instructions.
Computers don't experience emotions or feelings, basing actions on pre-determined instructions.
