1) Functional Unit (Or)
A computer system is logically divided into several functional units that work together to perform data processing. These units accept input, process the data, store information and produce output.
Accepts raw data and instructions from the user and enters them into the computer.
Converts the input data into machine readable form (binary) for processing.

Population = entire group being studied
Sample = subset of the population
Example
Population: all university students
Sample: 200 students surveyed
Parameter vs Statistic
Parameter → numerical value describing population
Statistic → numerical value from sample
Examples
p = true population proportion
p̂ (p-hat) = sample proportion
Sample proportion formula
p̂ = x / n
where
x = number of successes
n = sample size
