Explanation
The correct answer is DIPP. DIPP stands for Dual In-Line Plastic Package, which was a type of packaging used in the 8086 microprocessor. DIPP packages have two parallel rows of pins on opposite sides, allowing for easy insertion into a socket on a circuit board. This type of packaging was commonly used for early microprocessors and other integrated circuits.

Explanation
The correct answer is 640KB. This is because in the DOS operating system, conventional memory refers to the first 640KB of the computer's memory, which is accessible to DOS applications. This memory space is limited due to the design of the original IBM PC, and any additional memory would be considered "extended" or "expanded" memory.

Explanation
The correct answer is 80486. The 80486 processor, also known as the i486, was the first Intel processor to have a built-in coprocessor. This coprocessor, known as the 80487, provided additional mathematical and floating-point capabilities, enhancing the processor's performance in tasks that required complex calculations. The integration of the coprocessor into the processor itself eliminated the need for a separate chip, reducing cost and improving efficiency.

Explanation
The correct answer is BIOS, Operating system, Application software. This is because the BIOS (Basic Input Output System) is responsible for initializing hardware and booting the computer. The operating system then manages the computer's resources and provides a platform for running application software. Finally, application software refers to programs that perform specific tasks or functions on the computer. Therefore, the correct order reflects the natural hierarchy of how software components interact and depend on each other.

Explanation
If the system has 3 hard drives installed, you should see 5 options in FDISK's main menu. This is because FDISK allows you to perform various operations on the hard drives, such as creating partitions, deleting partitions, and setting active partitions. Therefore, each hard drive will have its own set of options, resulting in a total of 5 options in the main menu.

Explanation
The correct answer is 93,880 bytes. This is the size of the command.com file in Windows 95.

Explanation
OS/2, UNIX, and XENIX are operating systems that can utilize extended memory without the need for special drivers. Unlike DOS, which requires special drivers to access extended memory, these operating systems have built-in support for utilizing extended memory.

Explanation
COMMAND.COM is the correct answer because it is the primary command interpreter for MS-DOS and Windows operating systems. It interprets all commands entered by the user and executes them appropriately. It is responsible for managing the execution of batch files, running programs, and handling input/output operations. MSDOS.SYS is the system configuration file, IO.SYS is the device driver file, and AUTOEXEC.BAT is the batch file that automatically runs commands at startup. While these files are important for the functioning of the operating system, they do not interpret and execute user commands like COMMAND.COM does.

Explanation
The head parking zone refers to the area on a hard disk where the read/write heads are moved to when the disk is powered off or idle. It is typically located on the innermost cylinder of the disk. This is because the innermost cylinder has the smallest circumference, allowing the read/write heads to be safely positioned without risk of damaging the data stored on the disk. Therefore, the correct answer is the innermost cylinder.

Explanation
Electrostatic discharge (ESD) can cause damage to sensitive electronic components, including computer equipment. Even a small discharge of 10 volts can generate enough energy to disrupt the delicate circuitry and cause malfunctions or permanent damage. Therefore, it is important to take precautions and use ESD protection measures when handling computer equipment to prevent any potential damage.
