Information in one dimension refers to data that has a single value for each point along that dimension. Here are some examples:

• Temperature over time: Imagine a graph where the x-axis represents time (hours) and the y-axis represents temperature (degrees Celsius). This graph depicts temperature as a one-dimensional piece of information because at any given time on the x-axis, there's only one corresponding temperature value on the y-axis.
• Distance along a road: Imagine marking distances every kilometer along a straight road. This represents distance as a one-dimensional piece of information because at any given point on the road, there's only one corresponding distance value.
• Sound wave: A sound wave can be visualized as a graph with time on the x-axis and pressure on the y-axis. Although sound waves can have complex shapes, they are still considered one-dimensional because at any given point in time, there's only one pressure value.
• Signal strength: The strength of a cellphone signal can be represented as a number. This is one-dimensional information because there's just a single value for the signal strength at a specific location.

These are just a few examples. One-dimensional information is very common and forms the basis for many types of measurements and data analysis.
