1221. Angular is framework of_________?

• A. Php
• B. javaScript
• C. Python
• D. None

Explanation: Angular is a web-application framework in the JavaScript ecosystem, although modern Angular applications are written primarily in TypeScript. JavaScript is therefore the intended choice among these options.

1222. In a computer spreadsheet, value of formula (7-3)x(1+6)/4 is __________ ?

• A. 7
• B. 1.5
• C. 2
• D. 12Science

Explanation: Evaluate the parentheses first: (7−3)×(1+6)÷4 = 4×7÷4 = 7. Multiplication and division are then performed from left to right.

1223. Which programming language is much in vogue among users of microcomputers ________ ?

• A. FORTH
• B. LOGO
• C. APL
• D. ALGOL
• E. None of these

Explanation: FORTH became notably popular on microcomputers because it was compact, fast, and suitable for systems with limited resources. LOGO was mainly associated with educational programming, while APL and ALGOL were less typical choices for microcomputer users.

1224. Which is the limitation of high level language?

• A. Lower efficiency
• B. Machine dependence
• C. Machine level coding
• D. None of the above

Explanation: High-level languages are easier for humans to write but generally have lower efficiency than machine-level code because they require translation and additional processing. Machine dependence and machine-level coding are associated with low-level languages.

1225. Which of the following languages is more suited to a structured program?

• A. PL/1
• B. FORTRAN
• C. BASIC
• D. PASCAL

Explanation: Pascal was specifically designed to encourage structured programming through procedures, functions and clear control structures. The other listed languages are not as strongly associated with structured-programming education.

1226. Which of the following is a popular programming language for developing multimedia webpages ________ ?

• A. BASIC
• B. Assembler
• C. Java
• D. COBOL

Explanation: Java was widely used for interactive and multimedia content on web pages, especially through Java applets in earlier web development. BASIC, assembler and COBOL were not intended for this role.

1227. Who has been called the world's first Lady computer programmer?

• A. Ada Lovelace
• B. Allegra Byron
• C. Lady Augusta
• D. Allegra Noel-Byron

Explanation: Ada Lovelace is widely regarded as the first computer programmer because she wrote an algorithm for Charles Babbage's Analytical Engine. The other names are alternate or incorrect forms associated with her full name.

1228. Who invented Java programming language ?

• A. Deniss Ritche
• B. Linus Torvalds
• C. James Gosling
• D. Bajarnae

Explanation: James Gosling led the team that developed Java at Sun Microsystems, earning him the title commonly associated with Java's invention. Dennis Ritchie created C, while Linus Torvalds created Linux.

1229. PHP stands for ___________?

• A. Processor Hypertext Program
• B. Hypertext Preprocessor
• C. Pre Hypertext Processor
• D. Pre Processor Hypertext

Explanation: PHP is commonly expanded as Hypertext Preprocessor, a recursive name for a server-side scripting language. It was historically associated with “Personal Home Page,” but that option is not provided.

1230. FORTRAN stands for ________?

• A. Formula transistor
• B. Formula translation
• C. Formula train network
• D. Formula translation network

Explanation: FORTRAN comes from “Formula Translation,” reflecting its original design for scientific and mathematical computation. The other choices add words that are not part of the name.
