Basic CompTIA A+ Hardware Certification Exam! Quiz

The correct answer is BIOS, Operating system, Application software. This is because the BIOS (Basic Input/Output System) is a firmware that initializes the computer hardware and starts the operating system. The operating system then manages the computer's resources and provides a platform for running application software. Therefore, the BIOS comes first, followed by the operating system, and then the application software.

Electrostatic discharge (ESD) is a sudden flow of electricity between two objects caused by contact, an electrical short, or a dielectric breakdown. Computer equipment is sensitive to ESD and even a small discharge of 10 V can cause damage to the delicate electronic components. Therefore, it is true that an ESD of only 10 V is enough to damage computer equipment.

The correct answer is 640KB. In the early days of computing, DOS used a memory management system that divided the available memory into different sections. The conventional memory, also known as base memory, was the first 640KB of memory that was directly accessible to DOS applications. This memory was used to store the operating system, device drivers, and other essential components. The remaining memory was used for extended memory and expanded memory. Therefore, the conventional memory in DOS was limited to 640KB.

COMMAND.COM is the correct answer because it is the command interpreter for MS-DOS 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 providing a command prompt for the user to interact with the operating system.

The 80486 processor integrated the coprocessor.

The correct answer is DIPP. DIPP stands for Dual In-line Plastic Package, which was a type of packaging used for the 8086 microprocessor. It was a common packaging type for early microprocessors and integrated circuits, characterized by a rectangular body with two parallel rows of pins on opposite sides. DIPP packaging allowed for easy insertion and removal of the microprocessor from a socket, making it convenient for assembly and replacement.

The correct answer is the innermost cylinder. The head parking zone refers to the area on the hard disk where the read/write head rests when it is not actively accessing data. This zone is typically located on the innermost cylinder of the disk, as it allows for quicker access times when the head needs to move to a different location on the disk. Placing the head parking zone on the outermost cylinder would result in longer seek times, while having it on any random cylinder would not provide any specific benefits.

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. Each hard drive will have its own set of options, so with 3 hard drives, you will have a total of 5 options in the main menu.

OS/2, UNIX, and XENIX are local operating systems that can use extended memory without the need for special drivers. These operating systems are designed to efficiently utilize extended memory and provide support for it without any additional software or drivers. DOS, on the other hand, requires special drivers to access extended memory.
