Bit

The smallest unit of data in a computer, representing a single binary value of either 0 or 1

Byte

A unit of digital information that consists of 8 buts. It is the standard unit for measuring file size and storage capacity.

Abstraction

The process of simplifying complex systems by hiding unnecessary data and only showing important info, showing complex systems without needing to know their internal structure

Binary Number

A number expressed in the base -2 numeral system, which uses only two symbols: “0” and “1”. This is the primary language of computers.

Overflow Error

An error that occurs when a computer program tries to store a number that is too large for the allocated memory space.

Round-off Error

The difference between the calculated approximation of a number and its exact mathematical value. This often happens with floating-point numbers due to the limitations of binary representation

Analog Data

Continuous data represents physical measurements, such as sound waves or temprature.

Digital Data

Discrete data that represents information using a finite set of values, typically 0s and 1s.

Sampling

The process of converting an analog signal to digital by taking measurements at regular intervals

Lossless Compression

A data compression method that allows the original data to be perfectly reconstructed

Lossy Compression

A data compression method that loses some data to significantly compress the file size.
