Examples of High Level Languages include Python, Java, and C++.

A bit is the smallest unit of data in a computer. It is a binary digit, representing either a 0 or a 1. All other units of data, such as bytes, nibbles, and kilobytes, are composed of multiple bits. Therefore, the correct answer is bit.

The job of the storage unit is to save data and instructions to make them readily available. The storage unit is responsible for long-term storage of data and instructions, allowing them to be accessed and retrieved when needed. This is different from the cache unit, which stores frequently used data for quick access, and the input and output units, which handle the transfer of data between the computer and external devices.

Microsoft Word is classified as application software because it is a program that is designed to perform specific tasks or functions for the user. It is not a compiler, which is a software that translates code into machine language, nor is it a system software, which manages and controls the hardware and software resources of a computer. Additionally, Microsoft Word is not a programming language itself, so it cannot be classified as programming software. Therefore, the correct answer is application.

To select all the text in a MS Word document, you need to use the keyboard shortcut Ctrl+ A.

Formatting can be performed on both text and table elements as well as on menu elements. Therefore, the correct answer is that formatting is performed on both (a) text and (b) table.

The first generation of computers started with using vacuum tubes as the basic components. Vacuum tubes were used as electronic switches to perform calculations and store information in these early computers. They were large, fragile, and generated a significant amount of heat, leading to frequent malfunctions. However, they paved the way for the development of more advanced computer technologies in subsequent generations.

Page orientation refers to the direction in which content is displayed on a page. Landscape orientation is when the width of the page is greater than its height, resembling the shape of a landscape painting. This orientation is commonly used for documents that have a wide layout, such as spreadsheets or PowerPoint presentations. Therefore, "Landscape" is an example of page orientation.

The binary number system only consists of the digits 0 and 1. In the given options, all except "11E" are binary numbers because they only contain the digits 0 and 1. However, "11E" includes the letter 'E', which is not a valid digit in the binary system. Therefore, "11E" is not a binary number.

Margins refer to the blank space outside the printing area on a page. They are used to provide a visual buffer and ensure that the content of the page is not crowded or cut off at the edges. Margins also serve practical purposes such as allowing space for binding or hole punching, and providing room for notes or annotations.

Oracle is not an operating system, but rather a software company that specializes in developing and selling database management systems and enterprise software products. It is known for its flagship product, Oracle Database, which is widely used in the industry. Operating systems, on the other hand, are software that manage computer hardware and software resources and provide services for computer programs to run. Examples of operating systems include Windows, Linux, and DOS.

The command "Time" would be used to display the current time.

The option "Close" in the file drop-down menu is used to close an MS Word document. This option allows the user to exit the document without closing the entire MS Word application.

The binary system uses powers of 2 because it is a base-2 numeral system. This means that it only uses two digits, 0 and 1, to represent numbers. Each digit in a binary number represents a power of 2, with the rightmost digit representing 2^0, the next digit representing 2^1, and so on. Therefore, the binary system uses powers of 2 to express numbers in this base-2 system.

The correct answer is "4th". However, without any context or additional information provided, it is not possible to determine the exact meaning or relevance of "4th" in relation to the generation based on VLSI microprocessor. Therefore, an explanation cannot be provided.

To convert a binary number to decimal, each digit in the binary number is multiplied by 2 raised to the power of its position, starting from the rightmost digit with position 0. In this case, the binary number is 10101. Starting from the rightmost digit, the first digit is 1, which is multiplied by 2 raised to the power of 0, resulting in 1. The second digit is 0, so it does not contribute to the decimal equivalent. The third digit is 1, which is multiplied by 2 raised to the power of 2, resulting in 4. The fourth digit is 0, so it does not contribute. The fifth digit is 1, which is multiplied by 2 raised to the power of 4, resulting in 16. Adding up all these values, we get 1 + 4 + 16 = 21. Therefore, the decimal equivalent of 10101 is 21.

The statement "The fourth-generation was based on integrated circuits" is false. The fourth-generation of computers, which emerged in the 1970s, was actually based on microprocessors. Integrated circuits were utilized in the third-generation of computers, which came before the fourth-generation.

MS Word is the correct answer because it is a widely used software for creating and formatting documents, including resumes. It provides various templates and formatting options that make it easy to design a professional-looking resume. MS Excel is a spreadsheet software, not specifically designed for creating resumes. Dev C and Java are programming software, which are not suitable for making resumes.

The name of a word document displays in the title bar. The title bar is the horizontal bar at the top of the Word application window that shows the name of the currently active document. It also contains the minimize, maximize, and close buttons to control the window. The title bar provides a quick and easy way to identify the document you are working on.

A number of letters that appear little above the normal text is called superscript. Superscript is commonly used in mathematical equations, footnotes, and citations to indicate a smaller or raised character or number. It is visually represented by placing the text slightly higher than the baseline of the rest of the text.

The binary equivalent of the decimal number 10 is 1010. In binary representation, each digit can only be a 0 or a 1. The binary number 1010 represents 1*(2^3) + 0*(2^2) + 1*(2^1) + 0*(2^0), which simplifies to 8 + 0 + 2 + 0, resulting in 10.

The input unit is responsible for converting the data received from the user into a computer understandable format. This unit is responsible for receiving input from various input devices such as keyboard, mouse, and microphone, and then converting this input into a digital format that the computer can process. The input unit plays a crucial role in the overall functioning of the computer system by facilitating the communication between the user and the computer.

The correct answer is "Copy." The Copy command in MS-DOS is used to transfer files from one disk to another. It allows users to duplicate files and directories, preserving their original attributes and properties. By using the Copy command, users can easily move files between different disks or directories within the same disk.

The command "RD" is used to delete an empty directory. This command stands for "Remove Directory" and is specifically designed to delete directories that do not contain any files or subdirectories. It is the correct answer because the other options, such as DEL *.*, ERASE, and MD, are not used to delete directories. DEL *.* is used to delete files, ERASE is used to erase files, and MD is used to create directories. Therefore, the correct command to delete an empty directory is RD.
