The correct answer is 'Repeater' because a repeater is a device used in the physical layer of a network to regenerate and amplify signals to extend the reach of a network. It operates at the lowest layer of the OSI model, which is the physical layer responsible for transmitting raw data bits over a physical medium. Therefore, a repeater is the correct device used in the physical layer of IT networking.
The correct answer is 'Unshielded Twisted Pair' because UTP is a type of cable commonly used in networking that consists of pairs of insulated wires twisted together. This design helps reduce electromagnetic interference and crosstalk, making it a reliable choice for transmitting data. Therefore, UTP is the correct answer for the acronym 'UTP.'
The correct answer is 'Routing' because routing algorithms are specifically designed to determine the best path for transferring packets from a source to a destination in a computer network. These algorithms take into account factors such as network congestion, link quality, and other metrics to ensure efficient and reliable packet delivery. Therefore, routing is the most appropriate choice for deciding the path for packet transfer in a network.
The correct answer is 'Vector graphics' because Corel Draw is a software program specifically designed for creating and editing vector graphics. Vector graphics use mathematical equations to create shapes and images, allowing for scalability without losing quality. Corel Draw's tools and features are tailored to work with vector graphics, making it a popular choice for graphic designers and illustrators.
The correct answer is 'C. Visual Basic' because Microsoft Word uses Visual Basic for Applications (VBA) as its macro language. VBA is a programming language developed by Microsoft for creating custom applications within Microsoft Office programs, including Word. Therefore, Visual Basic is the language used by MS-Word to create Macros.
The correct answer is 'Ctrl N' because pressing these keys together is the keyboard shortcut for creating a new presentation in PowerPoint. This command allows users to quickly start a new presentation without having to navigate through menus or options. By using this shortcut, users can efficiently begin working on a new project in PowerPoint.
The correct answer is 'D. All of these' because all of the options listed (monitor, printer, and speaker) are examples of output devices. Output devices are hardware components that display or present data to the user, such as visual information on a monitor, printed documents from a printer, or sound from a speaker.
The correct answer is 'D. Lock Desktop' because pressing the Windows key + L on a keyboard locks the desktop, requiring the user to enter their password to unlock it. This feature is useful for quickly securing your computer when stepping away from it to prevent unauthorized access. It is a common keyboard shortcut used for security purposes in Windows operating systems.
The correct answer is 'Dialup' because it is a method of connecting a remote computer using a telephone line and a modem. This technology allows users to establish a connection with a remote computer by dialing a specific phone number. Therefore, 'Dialup' is the correct choice for connecting a remote computer.
The correct answer is 'Hard Copy' because it refers to any information that is printed on a physical paper. This term specifically distinguishes printed material from digital or electronic copies. Therefore, 'Hard Copy' accurately describes output that is physically printed on paper.
