What is the result of binary multiplication 10102 * 11002? Also, identify the MS Word feature for auto-correcting spelling and the type of computer-keyboard communication.

Here are the answers to the questions:

15. The feature in MS Word that helps you automatically correct common spelling mistakes is Autocorrect. * B

16. Communication between a computer and a keyboard primarily involves one-way transmission from the keyboard to the computer, which is Simplex communication. * D

17. To find the result of binary multiplication $1010_2 \times 1100_2$: First, convert to decimal: $1010_2 = 1 \cdot 2^3 + 0 \cdot 2^2 + 1 \cdot 2^1 + 0 \cdot 2^0 = 8 + 0 + 2 + 0 = 10_{10}$ $1100_2 = 1 \cdot 2^3 + 1 \cdot 2^2 + 0 \cdot 2^1 + 0 \cdot 2^0 = 8 + 4 + 0 + 0 = 12_{10}$ Multiply the decimal values: $10_{10} \times 12_{10} = 120_{10}$ Convert $120_{10}$ back to binary: $120 \div 2 = 60 \text{ remainder } 0$ $60 \div 2 = 30 \text{ remainder } 0$ $30 \div 2 = 15 \text{ remainder } 0$ $15 \div 2 = 7 \text{ remainder } 1$ $7 \div 2 = 3 \text{ remainder } 1$ $3 \div 2 = 1 \text{ remainder } 1$ $1 \div 2 = 0 \text{ remainder } 1$ Reading the remainders from bottom up gives $1111000_2$. None of the options exactly match $1111000_2$. However, if the question intended to ask for $1010_2 \times 110_2$: $1010_2 = 10_{10}$ $110_2 = 1 \cdot 2^2 + 1 \cdot 2^1 + 0 \cdot 2^0 = 4 + 2 + 0 = 6_{10}$ $10_{10} \times 6_{10} = 60_{10}$ Converting $60_{10}$ to binary gives $111100_2$, which matches option D. Assuming a typo in the question, the answer is D.

18. The circuit shows an OR gate with inputs A and B, followed by an AND gate with the output of the OR gate and input C. The output of the OR gate is $(A + B)$. The final output Y is the AND of $(A + B)$ and C, which is $Y = (A + B) \cdot C$. * A

19. float, int, and char are basic data types in C language. Num is not a standard basic data type. * C

20. ASCII primarily represents data in two standards: ASCII-7 (7-bit, 128 characters) and ASCII-8 (8-bit, 256 characters, also known as Extended ASCII). * C

21. A system that records items bought and produces a bill in a supermarket is a Transaction processing system. * A

22. The primary goal of project management is to complete the project on time and within budget. * D

23. PERT (Program Evaluation and Review Technique) is a technique used to estimate the duration and dependencies of tasks in a project. * D

24. A program in computer science is a sequence of instructions that specifies how to perform a computation. * D

25. A missing semicolon where one is required in a programming language is a violation of the language's grammar rules, which results in a Syntax error. * B

26. Algorithms can be represented as pseudocode, programs, or flowcharts. Syntax refers to the rules of a language, not a representation of an algorithm. * B

27. When an algorithm is written in the form of a programming language, it becomes a Program. * B

28. Assuming "1110" refers to a binary number $1110_2$, its decimal representation is: $$1110_2 = 1 \cdot 2^3 +
