BIOS
UEFI
The two services that Windows must provide for an ExpressCard are:
socket service
card service
What two laptop manufacturers provide their service manuals online free of charge?
Lenovo
Dell
DisplayPort
transmits digital video and audio and is slowly replacing VGA and DVI
DIMM
a type of memory slot found on a motherboard
Heat Sink
draws heat from the CPU and pipes it to a fan, which then blows heat out of the case
PCIe
a slot used for expansion cards or video cards on a motherboard
POST
a series of tests performed by the startup UEFI/BIOS when you first turn on a computer
SO-DIMM
a smaller type of memory slot typically used for laptops
Airplane mode
a computer is said to be in this mode when all wireless technologies are turned off
Bluetooth
a short-range wireless technology used to connect two devices in a small personal network
CPU
also called the processor, or microprocessor, does most of the processing of data and instructions for the entire system
MicroATX
reduces the total cost of a system by reducing the number of expansion slots on the motherboard, reducing the power supplied to the board, and allowing for a smaller case size
List and describe three front panel connectors you will likely see going from the front panel to the motherboard.
- Power SW: controls power to the motherboard, must be connected for PC to power up.
- HDD LED: controls drive activity light on front panel.
- Reset SW: used to reboot computer
What is an Accelerometer?
Gyroscope is a device that contains a disc that is free to move and can respond to gravity as device is moved. Used in mobile device.
What is the difference between a tablet and a phablet?
A computing device with a touch screen; larger than a smart phone. Tablets connect to WiFi, Bluetooth, cell networks. Phablet has same capabilities but is smaller than tablet and larger than phone.
What items might be considered field replaceable units in laptop?
memory modules, hard drive, keyboard, touchpad
How does working on and supporting a laptop differ from a desktop?
Replacement parts cost more, use compact hard drives, small memory modules. Require less power than desktop computers.
List some types of wearable technology devices, and describe how they can be used.
Smart watches, eyeglasses, headsets can be used to make phone calls, send texts, transmit data. Wearable fitness tech can measure heart rate, track miles jogged/biked.
List three components found on a motherboard.
CPU
expansion slots
memory slots
heat sink
What is the POST (power-on self test), and what can be done to troubleshoot this process?
Series of tests performed by the startup UEFI/BIOS when you first turn on a computer. Determine if you can communicate correctly with hardware components.
Describe the differences between BIOS and UEFI firmware.
Older BIOS manages essential devices before OS is launched. BIOS changes motherboard settings. UEFI more secure (still manages devices) but also assures boot is secure.
Describe the Near Field Communication (NFC) technology.
wireless technology that establishes a communication between two NFC devices within 4 inches of each other. NFC can be used to read an NFC tag (microchip)
