In a spreadsheet, data is organized using rows and columns. Rows are horizontal lines that contain individual records or data entries, while columns are vertical spaces that represent specific categories or attributes of the data. This structure allows for easy organization, manipulation, and analysis of data in a tabular format. Lines and spaces, as well as height and width, are not accurate representations of how data is organized in a spreadsheet.

MB/s is short for megabytes per second. This is a unit of data transfer rate, measuring the amount of data (in megabytes) that can be transferred in one second. It is commonly used to describe the speed or bandwidth of data transmission.

The correct answer is "world wide web." This is the term used to describe the system of interconnected hypertext documents accessed through the internet. The term "world wide web" was coined by Tim Berners-Lee in 1989 and has since become the standard way to refer to the internet and its content.

The word "homepage" is commonly used to refer to the main or starting page of a website. It is the first page that users see when they visit a website. Therefore, "homepage" is associated with web pages.

A secondary memory device is a type of storage device that is used to store data permanently. It is not directly accessible by the CPU. Out of the options given, only a disk can be considered as a secondary memory device. A disk, such as a hard disk drive or solid-state drive, is used to store large amounts of data even when the computer is turned off. The keyboard and printer are input and output devices respectively, which are not considered as secondary memory devices. Therefore, the correct answer is disk.

Ctrl+c is the correct key combination for copying in Windows. When this combination is pressed, it copies the selected text or file to the clipboard, allowing it to be pasted elsewhere using Ctrl+v. Ctrl+X is used for cutting, Ctrl+z is used for undoing, and Ctrl+A is used for selecting all.

Mazel Tov is not a type/kind of printer. It is a Hebrew phrase meaning "good luck" or "congratulations" and has no relation to printers. The other options listed, Inkjet, Laser, and Dot-Matrix, are all types of printers commonly used for printing purposes.

The control unit is a crucial component of the Central Processing Unit (CPU). It is responsible for coordinating and directing the operations of the CPU, including fetching instructions from memory, decoding them, and executing them. The control unit also manages the flow of data between the CPU and other devices, ensuring that instructions are executed in the correct sequence. The printer and mouse are peripheral devices that are not part of the CPU, while "None of the Above" is not a valid option as the control unit is indeed a part of the CPU.

The absence of a sound card does not affect the functionality of a computer system. While a sound card is responsible for generating audio output, it is not essential for the basic functioning of a computer. The operating system, hardware, and RAM are all crucial components that are necessary for the computer to operate properly. However, the absence of a sound card may result in the computer being unable to produce sound, but it will not prevent other essential functions such as running applications or performing tasks.

A browser is not a hardware device because it is a software application used to access and view websites and web pages. Hardware devices are physical components of a computer system, such as the hard disk, RAM, and mouse, which can be touched and interacted with. In contrast, a browser is a program that runs on the hardware devices and allows users to navigate the internet and display web content.

Windows Word is an example of application software because it is a program that is designed to perform specific tasks for the user, such as creating and editing documents. Application software is different from system software, which includes operating systems and utility programs that manage and control the computer's hardware and provide a platform for running applications.

BIOS stands for Basic Input Output System. It is a firmware that is embedded on a computer's motherboard. BIOS is responsible for initializing and testing hardware components during the booting process, and it provides basic communication between the operating system and the hardware. It also contains the necessary instructions to start the computer and load the operating system. Therefore, the correct answer is Basic Input Output System.

Tim Berners-Lee is considered the father of the World Wide Web (WWW) because he invented and developed the first web browser, HTTP (Hypertext Transfer Protocol), and HTML (Hypertext Markup Language) in 1989. His contributions revolutionized the way information is shared and accessed on the internet, making it accessible to everyone. Alan Turing, on the other hand, is known as the father of theoretical computer science and artificial intelligence, while Winton Surf is not associated with the invention of the WWW. Therefore, Tim Berners-Lee is the correct answer.

One Byte is equal to 8 bits.

A modem is a piece of hardware that converts a computer's digital signal into an analog signal that can be transmitted over telephone lines. This allows the computer to communicate with other devices or access the internet through a telephone line connection.
