261. IBM 1401 is_________?

• A. First Generation Computer
• B. Second Generation Computer
• C. Third Generation Computer
• D. Fourth Generation Computer

262. Which of the following is first generation of computer?

• A. EDSAC
• B. IBM-1401
• C. CDC-1604
• D. ICL-2900

263. ASCII stands for__________?

• A. American Stable Code for International Interchange
• B. American Standard Case for Institutional Interchange
• C. American Standard Code for Information Interchange
• D. American Standard Code for Interchange Information

265. When did John Napier develop logarithm?

• A. 1416
• B. 1614
• C. 1641
• D. 1804Science

Explanation: John Napier published his logarithms in 1614, making difficult multiplication and division easier through addition and subtraction. The other dates do not match this historical development.

266. __________represents raw facts, where-as__________is data made meaningful?

• A. Information, reporting
• B. Data, information
• C. Information, bits
• D. Records, bytes

267. Example of non-numeric data is_________?

• A. Employee address
• B. Examination score
• C. Bank balance
• D. All of these

Explanation: An employee address is non-numeric data because it is primarily text. An examination score and bank balance are numerical data, so “all of these” is incorrect.

268. CAD stands for_________?

• A. Computer aided design
• B. Computer algorithm for design
• C. Computer application in design
• D. Computer analogue design

Explanation: CAD expands to Computer-Aided Design, software used to create and modify engineering, architectural, and product designs. The other choices do not form the established expansion of CAD.

269. EBCDIC stands for__________?

• A. Extended Binary Coded Decimal Interchange Code
• B. Extended Bit Code Decimal Interchange Code
• C. Extended Bit Case Decimal Interchange Code
• D. Extended Binary Case Decimal Interchange Code
