What distinguishes a 'character set' from a single 'character' in the context of computing?
What distinguishes a 'character set' from a single 'character' in the context of computing?
- A character set represents continuous data, while a character is binary.
- A character set is a collection of characters that a computer recognizes, while a character is a single element within that set. (correct)
- A character represents the rate of data transfer, and a character set represents the number of transfers.
- A character is a compressed form of data; a character set is raw data.

Study Notes
- Analog data represents information with continuous, variable forms.
- American Standard Code for Information Interchange (ASCII) is a standard encoding system for text characters.
- It uses numeric values to represent letters, numbers, and symbols.
- Bandwidth is the maximum rate of data transfer across a network.
- It's measured in bits per second.
- Binary refers to a numerical system using only two digits: zero and one.
- It is used to represent data in computing.
- Boolean expression is a logical statement.
- It can only be true or false
- It uses operators like AND, OR, and NOT.
- Character is a single letter, digit, or symbol in writing text.
- Character set is a collection of characters that a computer can recognize and process.
- Examples include ASCII or Unicode.
- The compression ratio is the ratio of the original data size to the compressed data size, indicating how much the data has been reduced
- Control structure refers to constructs in programming.
- They control the flow of execution, like loops and conditional statements.
- Data is raw facts and figures.
- These can be processed to produce meaningful information.
- Data compression reduces the size of data.
- It saves space or transmission time.
