The correct answer is 'C. Mnemonics' because in assembly language programming, mnemonics are used to represent machine instructions. Mnemonics are short, easy-to-remember symbols that correspond to specific machine code instructions. Programmers use mnemonics to write assembly language code that can be easily translated into machine code by an assembler.
The correct answer is 'A. Young hacker' because it accurately describes the demographic profile of individuals who are most commonly associated with computer crimes. Research and studies have shown that many computer criminals tend to be young individuals with advanced technical skills who engage in hacking activities. This answer aligns with the common perception and understanding of the characteristics of individuals involved in computer crimes.
The correct answer is 'B. Central Processing Unit' because the CPU is responsible for carrying out instructions and performing calculations in a computer, similar to how the brain processes information in a human. The CPU is considered the 'brain' of the computer because it controls all the operations and functions of the system.
The correct answer is 'B. Shift Space bar' because pressing Shift along with the Space bar allows you to select the entire row in Excel. This shortcut helps you quickly highlight and work with an entire row of data without having to manually click and drag.
The correct answer is 'C. 1024768' because this is the standard resolution for VGA (Video Graphics Array) displays. VGA resolution refers to a display resolution of 1024 pixels in width by 768 pixels in height, which is commonly used for computer monitors and televisions. Therefore, 'C. 1024768' is the correct answer that aligns with the VGA resolution standard.
The correct answer is 'C. High level' because a source program is typically written in a high-level programming language, which is designed to be easily understood by humans and is closer to natural language. High-level languages are more abstract and do not require the programmer to have a deep understanding of the computer's hardware or architecture. This makes it easier for programmers to write and read code, leading to faster development and fewer errors.
The correct answer is 'C. Network' because e-mail messages are exchanged through a network of computers connected to each other. A network allows for the transmission of data between different devices, enabling the communication and exchange of messages through the e-mail system.
The correct answer is 'Adhoc mode' because in this mode, computers can communicate with each other directly without the need for a central access point. This allows for a peer-to-peer connection between devices, enabling them to send frames directly to each other without going through a central network device.
The correct answer is 'B. Ctrl Backspace' because pressing Ctrl and Backspace together will move the cursor to the active cell in Excel. This shortcut allows users to quickly navigate to the cell they are currently working on without having to manually scroll or search for it. It is a commonly used shortcut for efficient navigation within Excel spreadsheets.
The correct answer is 'B. Spybot' because Spybot is a type of malicious software designed to gather user information without their knowledge or consent. It then sends this information to a third party through the Internet. This behavior aligns with the description provided in the question.
