2. Which of the following is an example of alphabetic data?

@, #, $

1, 2, 3

A, B, C

%, &, *

Alphabetic data consists of characters that represent letters of the alphabet. In this case, the options include symbols, numbers, and letters. Among the choices, "A, B, C" clearly consists of alphabetic characters, which are letters. The other options contain special symbols or numeric values, which do not qualify as alphabetic data. Therefore, "A, B, C" is the only example that fits the definition of alphabetic data.

3. Which of the following are examples of symbolic data?

A, B, C

1, 2, 3

@, #, $, %, &

X, Y, Z

Symbolic data refers to non-numeric values that represent categories, symbols, or identifiers rather than quantities. In this context, the symbols @, #, $, %, and & are all examples of symbolic data as they are used to convey meanings or functions in various contexts, such as social media or programming. In contrast, the other options (A, B, C; 1, 2, 3; X, Y, Z) either represent letters, numbers, or other forms of data that do not fit the symbolic category.

5. A computer processes raw data and converts it into meaningful ____.

A computer takes raw data, which consists of unorganized facts and figures, and processes it through various operations such as calculations, sorting, and analysis. This transformation results in information, which is structured and organized data that provides context, relevance, and purpose. Information is essential for decision-making, problem-solving, and understanding trends, making it valuable for individuals and organizations alike.

6. A computer can process data without following any specific order or instructions.

True

False

Computers operate based on specific instructions and algorithms, processing data in a predetermined order to achieve desired outcomes. Without following these instructions, a computer would not be able to execute tasks effectively or produce accurate results. The systematic approach ensures that data is handled consistently and reliably, making it essential for all computing processes. Thus, the statement that a computer can process data without any specific order or instructions is incorrect.

7. Numbers such as 1, 2, 3, and 4 are classified as which type of data?

Symbolic data

Alphabetic data

Numeric data

Graphical data

Numbers like 1, 2, 3, and 4 are classified as numeric data because they represent quantities or values that can be measured or counted. Numeric data is characterized by its ability to undergo mathematical operations, such as addition or subtraction, and can be used in statistical analysis. Unlike symbolic or alphabetic data, which consist of letters and symbols without inherent numerical value, numeric data directly conveys numerical information, making it essential for various mathematical and analytical applications.
