1. The correct answer is (A) Microsoft. To find this answer, you can search for the history of the IBM PC and the development of its operating system. IBM selected Microsoft to create the operating system for the IBM PC, which eventually became known as MS-DOS.
2. The correct answer is (C) Graphical User Interface. To find this answer, you can search for the features and developments of the Macintosh LISA computer. One of its significant features was the introduction of the Graphical User Interface (GUI), which allowed users to interact with the computer using icons, windows, and a mouse.
3. The correct answer is (D) Windows. To determine which of the options is an operating system, you can exclude the ones that are not operating systems. Microsoft, MAC, and Apple are all companies or brands, while Windows is an operating system developed by Microsoft.
4. The correct answer is (A) Expansion slot. To determine which option is not a function associated with a motherboard, you can eliminate options that are commonly found on a motherboard. Expansion slots, memory slots, and processor sockets are all common functions of a motherboard, while peripherals are devices that connect to the motherboard, such as keyboards, mice, and monitors.
5. The correct answer is (B) Applet. To determine a significant and powerful aspect of the Java language, you can eliminate options that are not relevant to its features. A source program and compiler are essential components of programming languages, while an object program is the compiled and executable version of a source program. In the case of Java, applets are a powerful aspect of the language, as they are small applications that can be embedded in webpages and run on various platforms.
6. The correct answer is (D) DVD. To determine which option does not have a computer in it, you can eliminate options that are known to have embedded computers. Automobiles, airplanes, and cell phones often have embedded computers for various functions and systems, but DVDs do not typically contain built-in computers.
7. The correct answer is (A) It jumps to a non-sequential line number. To understand what a branch in a computer program means, you can eliminate options that do not describe the concept. A branch in a computer program refers to a jump to a non-sequential line number, allowing the program to execute different paths of code based on certain conditions or decision-making.
8. The correct answer is (C) 5. To determine how many generations of computer languages have been developed since the middle of the 20th century, you can count the distinct periods or advancements in programming languages. There have been five generations of computer languages, with each generation representing significant advancements in programming concepts and technologies.
9. The correct answer is (C) read and write. To define literacy, you can eliminate options that do not relate to the ability to read and write. While walking and talking, memorizing and reciting, and thinking and dreaming are all important capabilities, literacy specifically refers to the ability to read and write.
10. The correct answer is (D) Computers have had both a positive and negative effect on society. To determine what the description of computers as "complex" can mean, you can consider the various aspects of complexity associated with computers. While some may view complexity in terms of technical components or hard-to-use software features, a more encompassing view is that computers have had both positive and negative effects on society, which contributes to their overall complexity.
