Computer Hardware and Networking Quiz

DDR3 is the type of RAM most commonly used in desktop computers due to its high speed and cost-effectiveness.

Vertical streaks in laser printer output indicate a problem with the imaging drum. The drum transfers toner to the paper, and streaks suggest damage or a build-up of debris.

The error message indicates a HDCP (High-bandwidth Digital Content Protection) issue. The projector likely doesn't support the necessary HDCP protocol to play copy-protected content.

A channel reserved for licensed use isn't accessible for non-carrier-grade wireless backhaul because it's dedicated to specific services or operations.

Double images on printouts suggest a problem with the transfer roller, which moves the toner image from the drum to the paper. A worn or dirty roller can cause this issue.

Enabling TPM (Trusted Platform Module) is crucial for creating virtual machines on a host. TPM ensures the integrity and security of the VM environment.

A user's computer not receiving a network connection usually indicates a problem with the physical network connection. Checking the patch panel for the user's port will pinpoint the issue.

A faded image appearing on a laptop screen, even in bright settings, usually indicates a problem with the screen's backlight.

S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology) is a feature that monitors hard drive health. A failure in this system indicates potential imminent hard drive failure.

A single beep followed by an error message on boot usually indicates a problem with the system's RAM (Random Access Memory).

The weather application's frequent location checks using GPS drain the battery quickly. Configure less frequent checks using cellular location to conserve battery and keep accurate weather updates.

VT-d (Virtualization Technology for Directed I/O) enables virtual machines to directly access hardware devices, improving performance and security for virtualized environments.

A hot, slow, and poorly charging phone indicates a faulty battery. The battery may be unable to hold a charge or may be causing overheating issues.

Hyperthreading is a technology that allows a single CPU core to handle multiple threads simultaneously. This requires enabling VT-d (Virtualization Technology for Directed I/O) to run properly.

A faulty charging port can cause overheating, slow charging and battery draining issues. It may fail to properly connect to the charger, resulting in these symptoms.

A switch is a network device that separates broadcast domains, preventing broadcasts from reaching every device on the network. This improves performance and security by limiting traffic to specific segments.

The most likely cause of a phone's charging port failing is a physical obstruction, such as lint, debris, or damage to the port itself. These issues prevent proper connection and charging.

When a network administrator investigates a network access issue, the first step is to check the DHCP server to ensure it's assigning valid IP addresses to devices. This is crucial for devices to connect to the network effectively.

The issue with the printer printing A4-sized labels with white space in the middle is likely due to the incorrect page orientation. This means the document is being printed vertically when it should be printed horizontally.

A clicking sound from a workstation's hard drive indicates a potential failure. This sound often suggests the hard drive's head is struggling to read and write data due to wear or damage, and may indicate imminent failure.

After identifying an issue and backing up data, the next step is to establish a probable cause for the problem. This requires research, analysis, and potentially gathering more information.

When a laptop can't access network resources, it's essential to check the DHCP server. This ensures the laptop has a correct IP address and configuration to connect to the network.

Cross-platform virtualization allows running software designed for one operating system on a different operating system. For example, using a virtualization solution like Parallels Desktop or VMware Fusion on macOS, you can run Windows applications within a virtual machine, enabling you to seamlessly use both operating systems.

DSL (Digital Subscriber Line) uses existing telephone lines to provide internet access. The site likely uses DSL because POTS (Plain Old Telephone Service) lines, which are the traditional phone lines, are not working, suggesting a DSL connection that shares those lines.

A load balancer distributes incoming traffic across multiple servers to ensure optimal utilization and prevent overload. By directing user requests to different servers, the load balancer keeps each server functioning efficiently.

Inquire about possible changes should be the first step in troubleshooting a failing thumbprint scanner. This involves asking the user if any recent updates, software installations, or hardware changes might have affected the scanner.

The tech should check the printer paper path to locate any obstructions. This involves examining the paper tray, rollers, and any other areas where paper might be jammed. Checking for obstructions can pinpoint the exact location of the paper jam and allow for a quick fix.

PaaS (Platform as a Service) provides a complete environment for application development and deployment. It includes all the necessary software, tools, and infrastructure required to build, test, and run applications. This is beneficial for app development teams as they don't need to manage the underlying infrastructure.

A storage device that uses a non-volatile memory chip for faster data access and boot times. It typically comes in a small form factor and is commonly found in modern computers.

Two-factor authentication requires two distinct methods of verification, typically a password and a second factor like a fingerprint or a code from a mobile app, to access an account.

A web server is primarily responsible for hosting websites and delivering web content to users. It responds to requests for web pages, images, and other files, making them accessible on the internet.

The issue is likely due to a faulty keyboard. The external keyboard works fine, indicating the problem isn't with the computer but the internal keyboard.

Mobile device management (MDM) software allows administrators to control and manage smartphones, tablets, and other mobile devices within an organization. They can set up policies, restrict access, and wipe data remotely for security.

The printer's printhead is too hot, causing the ink to smudge on the paper. Adjusting the temperature down will help solve the issue.

To increase a laptop's performance for working with a large database, consider adding more RAM. This provides the operating system and database applications with more memory to handle the workload.

Replacing the hard drive with a solid-state drive (SSD) can significantly boost performance, especially for a database workload. SSDs offer faster read and write speeds compared to traditional HDDs.

A VPN (Virtual Private Network) establishes a secure connection between a remote user’s laptop and a corporate server over a public network, like the internet, ensuring confidentiality and integrity of data.

The display settings on the computer need to be configured to extend or duplicate the screen to the projector. This setting will ensure the projector receives the signal properly.

A PoE injector provides power over the Ethernet cable to the IP phone, allowing it to boot even when connected to an unmanaged switch that doesn't provide PoE.

Adjusting the lens on the projector can sharpen the images, potentially fixing the fuzzy display issue.

The tablet or PC settings should be checked for any touch screen-specific settings to ensure they are enabled and functioning correctly.

DHCP (Dynamic Host Configuration Protocol) assigns IP addresses to networked devices automatically, based on their MAC addresses. This allows devices to consistently receive the same IP address.

The HDMI cable that connects the laptop to the projector may be faulty or incompatible leading to the lack of display.

The television's HDMI-ARC port is specifically designed for audio return channels. If it's not being used, the audio from the conference call might not be playing on the TV.
