কম্পিউটার MCQ সমাধান

S1. Ans.(c)

Sol. The My Documents folder is a user-specific directory where personal files and documents are stored in the Windows operating system. However, it does not exist directly on the taskbar. The Quick Launch, Start Menu, and Address bar are common components found on the taskbar.

S2. Ans. (d)

Sol. In DOS, the file extensions commonly used are EXE, BAT, and COM. The EXE extension is used for executable files, containing machine code instructions. BAT files are script files with a series of commands, while COM files contain specific instructions for the operating system. All of these are file extension(s) in DOS.

S3. Ans.(c)

Sol. A dumb terminal is a computer terminal that consists mostly of just a display monitor and a keyboard (and perhaps a mouse as well). It has no internal CPU (central processing unit), and thus has little or no processing power.

S4. Ans.(b)

Sol. Backup refers to the process of creating a copy of data from its original source to another destination for the purpose of data preservation and recovery. It involves duplicating important files, documents, or information to ensure their availability in case of data loss or system failure. By creating backups, data can be restored from the backup copy when needed, providing an extra layer of protection against data loss.

S5. Ans.(d)

Sol. The intention of social engineering is to extract information from a target by taking advantage of the basic human nature of being helpful.

S6. Ans.(d)

Sol. Integrity is the assurance that the information is trustworthy and accurate, and availability is a guarantee of reliable access to the information by authorized people.

S7. Ans.(c)

Sol. A polymorphic virus is a complicated computer virus that affects data types and functions. It is a self-encrypted virus designed to avoid detection by a scanner. Upon infection, the polymorphic virus duplicates itself by creating usable, albeit slightly modified, copies of itself.

S8. Ans. (a)

Sol. Login is the process of connecting/ accessing to an account.

S9. Ans.(d)

Sol. Guided Transmission Media uses a “cabling” system that guides the data signals along a specific path. The data signals are bound by the “cabling” system. Guided media are twisted-pair cable, coaxial cable, and fiber-optic cable. Wi-Fiis not a guided media.

S10. Ans.(b)
