Study Notes
RAM Installation
- DDR3 is the most commonly used type of RAM in desktop computers.
- SODIMM is typically used in laptops, not desktops.
- ECC RAM is used in servers for error correction.
- VRAM is specialized for video cards, not standard desktop usage.
Laser Printer Issues
- Vertical streaks on printouts are often caused by a worn drum.
- A transfer belt, roller, and ribbon are less likely causes of streaking.
HDMI Error with Projector
- HDMI error stating "Blocked due to Copy Protection" is related to HDCP protocol support.
- A compatible cable standard like DisplayPort may not resolve HDMI-specific issues.
- Switching settings in the projector to enable content protection may be necessary.
Wireless Backhaul Channel Selection
- A heavily polluted RF environment can affect wireless channel selection.
- Reserved channels for licensed use cannot be selected freely.
- Vendor unlocking may be required for certain channels.
Laser Printer Double Image
- Double images on printouts are typically due to a worn fuser.
- Maintenance kits can affect printer performance and should be checked regularly.
VM Host Configuration
- Creating VMs may fail if multithreading is not enabled in the BIOS settings.
- Other settings like TPM and Fast Startup are less likely to impact VM creation.
Identifying Patch Panel Ports
- A toner probe is the best tool for identifying unlabeled ports on a patch panel.
- Other tools like crimpers and punchdown tools are not suited for this task.
Projector Audio Issues
- To resolve projector audio issues, utilizing an HDMI connection is recommended.
- Other connections like VGA and DVI may not carry audio signals.
Network Speed Limitations
- Cat 5 cable restricts transfer speeds to 100Mbps despite using a Gigabit LAN card.
- Replacing with Cat 5e or higher is necessary for Gigabit speeds.
Webcam Functionality
- Closing other video software might resolve conflicts with the webcam.
- Compatibility adjustments and reseating the webcam may also be beneficial.
Mobile Device Authentication
- NFC must be enabled on mobile devices for authentication with new security measures.
- Bluetooth, biometrics, and PIN are not required for this specific authentication method.
MIMO Technology Standards
- 802.11n is the standard that supports MIMO (Multiple Input Multiple Output) technology.
- Older standards like 802.11a, b, and g do not support MIMO.
PC Display Issues
- "No input signal detected" can be resolved by checking the monitor's power connections.
- Changing BIOS settings or connector settings may be unnecessary initially.
Touchscreen Input on Mobile Devices
- A digitizer enables the input functionality on a mobile device's touchscreen.
- Other components like OLED, inverter, and CMOS sensor serve different roles.
