Study Notes
Printing Preferences
- To change paper size setting for printing, go to Printing Preferences through Print dialog box or Devices and Printers section in Control Panel.
- Paper size can be adjusted to match the size of paper loaded in the printer.
Power Supply
- When selecting a power supply for a business workstation, input voltage is the most important parameter to consider, especially when working internationally with different voltage standards.
RAM
- DDR5 is the most likely type of RAM to be used in a desktop computer.
- SODIMM is a smaller form factor of memory module typically used in laptops or compact systems.
- ECC is a type of RAM used in servers and workstations for data integrity.
- VRAM is a specialized type of RAM used for graphics processing units (GPUs).
Inventory Management
- Barcode scanners can quickly and accurately scan barcodes on products, connecting to software systems that update inventory levels in real-time.
Error Messages
- "No input signal detected" error message indicates that the monitor is not receiving a signal from the computer.
- Solution: change connector settings on the monitor, ensure cable is securely plugged in on both ends, and check power plug on monitor and PC.
Network Tools
- A toner probe is a network tool used to trace network cables and identify the correct port on a patch panel.
DNS Database Records
- AAAA record maps a domain name to the corresponding IPv6 address (128-bit).
Memory Types
- SODIMM is a smaller form factor of DIMM used in laptops, notebooks, and small form factor computers.
Data Retention
- SSDs use non-volatile flash memory to store data even when power is turned off, making them suitable for long-term data storage.
Incident Reporting
- After reporting an incident, document the incident to create a record of what happened, which can be used for future reference.
Video Connectors
- HDMI is a digital interface that supports high-definition video and multi-channel audio, making it a popular choice for connecting devices to TVs and projectors.
Cable Categories
- Cat 5 cables are capable of supporting network speeds up to 100 Mbps.
Screen Issues
- A failing backlight and inverter can cause a laptop screen to flicker.
Hibernation
- When a computer hibernates, the operating system saves the contents of RAM to the hard disk and then shuts down the computer.
Upgrading to SSD
- Before replacing a laptop's HDD with an SSD, create a backup of the data on the HDD to avoid losing important data.
Cloud Providers
- IaaS providers offer virtualized computing resources, allowing organizations to move their servers, routers, firewalls, and switches to the cloud.
Video Conferencing Issues
- When a webcam is not recognized by video conferencing software, try closing other video software and retrying before checking the driver or replacing the webcam.
Motherboard Replacement
- For an Intel Core i7-11700K processor, the replacement motherboard should have an LGA 1200 socket.
Integrated Graphics
- Intel UHD Graphics 630 is an Integrated GPU that can take over tasks normally executed by a dedicated graphics controller.### Integrated GPUs
- Integrated GPUs are capable of taking over certain graphics processing tasks that are normally executed by a dedicated graphics controller.
- They may not have the same level of performance as a dedicated graphics card, but they are often sufficient for casual gaming and other graphics-intensive tasks.
Cloud Computing
- SaaS (Software as a Service) is a cloud computing model where software applications are hosted on a cloud provider's servers.
- With SaaS, users can access the software from any device with an internet connection, without the need for local installation.
- Examples of SaaS include Microsoft 365 and Google Workspace.
Virtualization
- Elasticity in virtualization refers to the ability to dynamically adjust the computing resources allocated to virtual machines (VMs) or containers.
- Resources can be easily scaled up or down depending on the current demand, without the need for physical hardware changes.
Projector Troubleshooting
- If a projector is overheating, it may automatically shut off as a safety measure to prevent damage to the device.
- Cleaning the filter is a simple and effective way to address overheating issues in a projector.
Processor Cooling
- Thermal paste is used to attach a cooling system to a processor.
- Thermal paste fills microscopic gaps and imperfections between the processor and the cooling system, allowing for better thermal conductivity and more efficient heat dissipation.
Networking Issues
- An IP address conflict occurs when two devices on the same network are using the same IP address.
- Setting a device to obtain an IP address automatically via DHCP can prevent IP address conflicts.
DVI Types
- DVI-D (Digital) supports only digital video transmission and does not support analog signals.
- DVI-A (Analog) supports only analog signal transmission and does not support digital signals.
- DVI-I (Integrated) supports both analog and digital signal transmission.
Cabling Types
- SATA (Serial ATA) is used to connect hard drives and solid-state drives (SSDs) to a computer's motherboard.
- IDE/PATA (Integrated Drive Electronics/Parallel ATA) is an older type of cabling used to connect hard drives and optical drives to a computer's motherboard.
- SCSI (Small Computer System Interface) is a high-performance interface used to connect devices such as hard drives, tape drives, and scanners to a computer.
- eSATA (External SATA) is a variant of SATA that allows for external devices to be connected to a computer via a SATA cable.
Mobile Processors
- ARM processors are designed to be power-efficient, which makes them suitable for mobile devices.
VGA Cables
- VGA (Video Graphics Array) cables are primarily used to transmit video signals from a computer to a monitor.
- The video signal carried through a VGA cable is analog.
UPS Devices
- Laser printers should not be connected to a UPS (Uninterruptible Power Supply) device because they can consume a lot of power and overload the UPS.
Computer Hardware
- A four-core processor is helpful for gaming because it can handle more demanding tasks.
- A high-capacity hard drive is necessary for storing games, videos, and other media files.
Motherboard Components
- A jumper on a motherboard can be used to reset the BIOS to its default settings, including removing the boot password.
Printer Installation
- After installing a printer, the next step is to print a test page to ensure that the printer is functioning properly.
Router Configuration
- An Ethernet cable is used to connect a cable modem to a SOHO router.
Wireless Networks
- Channel 6 is one of the three non-overlapping channels recommended for use in the 2.4GHz frequency band for 802.11 wireless networks.
Expansion Slots
- PCIe (Peripheral Component Interconnect Express) is the appropriate type of expansion slot to use for a high-performance graphics card.
Hard Disk Drive Systems
- The three major components of a hard disk drive system are the hard disk, drive interface, and disk controller.
RAID Configuration
- Checking the event log for any cache issues is the first step in troubleshooting a slow-running Windows CAD workstation that uses RAID 10 and has dual GPU cards.
Network Cabling
- Plenum-rated cables are specifically designed to be used in air handling spaces, such as drop ceilings, where there is a high risk of fire.
eSATA Connectors
- The eSATA connector features a distinct L-shape that prevents improper insertion of the connector plug into the eSATA port.### Spam Filters
- Spam filters commonly use SMTP protocol and port number 25.
Secure Laptops

Workstation Issues
- A workstation that crashes frequently may be due to overheating, and forgetting to connect case fans during the build process.
Printer Issues
- When a printer's IP address changes, creating an IP reservation for the printer on the DHCP server can ensure that the printer always has a consistent IP address.
WiFi Issues
- A weaker WiFi signal after replacing an LCD display may be due to the new LCD panel causing interference with the antenna.
Network Security
- A user who selects the wrong wireless network profile (home, work, or public) may not be able to access office network resources.
IP Addressing
- DHCP (Dynamic Host Configuration Protocol) servers assign dynamic IP addresses to devices on a network.
PC Components
- Case fans commonly come in 80 mm and 120 mm sizes.
Device Manager
- An exclamation point next to a device in the Device Manager indicates that a driver is not properly installed for the device.
Beep Codes
