Question 1/7

Which of the following are considered computer hardware?

Right Answer

Computer hardware refers to the physical components of a computer system. The motherboard is a hardware component that connects and allows communication between various parts. Drivers, operating systems, and Microsoft Office are software, not physical devices. Hardware is tangible, while software provides the instructions to operate the hardware.

Question 2/7

Which of the following are considered input devices?

Right Answer

Input devices allow users to enter data into a computer. Keyboards and scanners send information into the system for processing. Monitors and printers are output devices because they display or print the results of processed data. Input devices serve as the starting point in the data flow.

Question 3/7

Which computer function takes data through a series of procedures as defined by a set of instructions?

Right Answer

Processing is the function where raw data is transformed into meaningful output by following predefined instructions. The CPU, or processor, handles this role. It uses logic and arithmetic operations to interpret and manipulate data. This step is essential for completing tasks and generating results.

Question 4/7

You need to replace a broken monitor on a desktop system. You decide to replace it with a spare monitor that is made by a different manufacturer than the desktop computer, and it still works with the computer. Which computer design concept makes this possible?

Right Answer

Standardization ensures that hardware components from different manufacturers follow the same protocols and physical interfaces. This allows devices like monitors to work across different systems without compatibility issues. It promotes interoperability and flexibility in system upgrades or replacements. Thanks to standardization, users aren’t locked into a single brand.

Question 5/7

You are assembling components in a network rack and need a device that connects three network segments. Which of the following devices will meet your networking needs?

Right Answer

An Ethernet router is used to connect multiple network segments and route traffic between them. It operates at Layer 3 of the OSI model and manages IP addressing. While switches and patch panels connect devices within the same network, routers link separate networks. Routers are essential for communication between different subnets.

Question 6/7

Which of the following components on the network rack should you use to connect the wires from the office wall plates?

Right Answer

An Ethernet patch panel organizes and connects incoming and outgoing LAN cables. Office wall plate cables are terminated on the patch panel for easy management and reconfiguration. From the patch panel, patch cords connect to network switches or other devices. It serves as a central point for network cable management.

Question 7/7

our local area experiences brownouts or blackouts during frequent electrical storms. Which of the following components could you add to your network rack to help protect your servers from brownouts or blackouts?

Right Answer

A UPS (Uninterruptible Power Supply) provides backup power during electrical outages and voltage drops. It protects servers from data loss and hardware damage caused by sudden shutdowns. During storms, it ensures critical devices remain powered and safe. A UPS is a vital part of any network rack in unstable power environments.
