The correct answer is 'D. Compact Disk Read Only Memory' because CD-ROMs are a type of compact disk that can only be read and not written to or erased. The term "Read Only Memory" indicates that the data on the CD-ROM is permanently stored and cannot be altered. This acronym accurately describes the function and purpose of CD-ROMs in computing.
The correct answer is 'D. peripheral device' because a peripheral device is an external hardware component that can be added to a computer system to provide additional functionality. These devices are not essential to the basic operation of the computer but can enhance its capabilities. Therefore, a peripheral device fits the description of equipment that can be added to a computer system to enhance its functionality.
The correct answer is 'Entered at different locations where it originates' because distributed data entry allows for data to be inputted from multiple locations where the data originates. This enables efficient and simultaneous data entry from various sources, improving accuracy and reducing the burden on a single data entry point.
The correct answer is 'Identify and eliminate' because an anti virus program is specifically created to detect and remove computer viruses from a system. This answer accurately reflects the main purpose and function of an anti virus program in protecting computers from malicious software.
The correct answer is 'Case-based reasoning' because this technique involves deriving rules from real-world case examples. In case-based reasoning, new problems are solved by comparing them to past cases and adapting solutions from similar situations. This process allows for the extraction of knowledge and rules from specific instances, making it an effective data mining technique for deriving insights from real-world scenarios.
The correct answer is 'CTRLF12' because pressing the 'CTRL' key along with the 'F12' key is the specific combination used to maximize or restore a selected window in most Windows operating systems. This key combination is a commonly used shortcut for this action and is recognized by the system to perform the desired function efficiently.
The correct answer is 'D. Data naturally needs to flow in and out in serial form' because serial access memories are designed to read and write data sequentially, one bit at a time. This makes them suitable for applications where data needs to be processed in a linear fashion, such as in streaming or communication systems. Therefore, the nature of serial access memories aligns with the requirement for data to flow in and out in serial form.
The correct answer is 'D. Personalization' because personalization is typically the final step in customizing a pop-up menu or refresh bar. This function allows users to tailor their experience to their preferences, making it a logical last step in the process. Additionally, personalization is often the last function listed in menu options, further indicating that it is the final step in the process.
The correct answer is 'Excel' because .xls is the file extension used for Microsoft Excel files. Excel is a popular spreadsheet program developed by Microsoft, and files created in Excel are saved with the .xls extension. This extension helps identify and open Excel files specifically.
The correct answer is 'Internetwork' because it refers to the connection of multiple networks to create a larger network. This term specifically describes the concept of linking different networks together to enable communication and data exchange between them. Therefore, 'Internetwork' accurately captures the idea of combining two or more networks.
