Chap7 Flashcards
What is the purpose of configuring laptop power settings?
To better manage power usage and ensure efficient battery use.
This is part of power management, which controls electricity flow to computer components.
What does ACPI stand for?
Advanced Configuration and Power Interface.
ACPI helps create power management schemes for optimal laptop performance.
What system states can be affected by configuring power settings in BIOS or UEFI?
- System states
- Battery and AC modes
- Thermal management
- CPU PCI bus power management
- Wake on LAN (WOL)
These settings help optimize the laptop’s performance and power efficiency.
What is the range of the most common Bluetooth technology?
Approximately 33 ft (10 m).
Bluetooth technology facilitates voice, music, videos, and data transfer.
What is required for Bluetooth devices to connect for the first time?
Pairing using a PIN for authentication.
Bluetooth supports 128-bit encryption and PIN authentication for security.
What is tethering in the context of cellular WAN?
Connecting other devices to the Internet using a mobile phone.
This can be done via Wi-Fi, Bluetooth, or USB cable.
What is the size of an ExpressCard/54?
75mm x 54mm.
It is used for various interfaces like PCI Express and USB.
What does a smart card reader do?
Reads and writes data to smart cards.
Smart cards have embedded microprocessors and can hold more information than magnetic stripes.
What type of memory module do most laptops use?
SODIMM.
SODIMMs are smaller than DIMMs used in desktops and vary by DDR version.
What are customer-replaceable units (CRUs)?
Components that can be replaced by the customer, such as the laptop battery and RAM.
Parts that should not be replaced by customers are called field-replaceable units (FRUs).
What are signs that a laptop battery may need to be replaced?
- Does not hold a charge
- Overheats
- Leaking
A replacement battery must meet or exceed manufacturer specifications.
What is the width of most internal storage devices for laptops?
1.8 in. (4.57 cm) or 2.5 in. (6.35 cm).
These drives are typically CRUs unless a warranty requires technical assistance.
What is the function of Airplane Mode on mobile devices?
Turns off all cellular, Wi-Fi, and Bluetooth radios.
This mode is useful when traveling on an airplane or in areas where data access is restricted.
What is a hotspot?
A cellular device used to provide an internet connection to other devices.
This allows devices to connect using Wi-Fi to share a cellular data connection.
What does Bluetooth pairing involve?
Establishing a connection between two Bluetooth devices to share resources.
This may involve entering a PIN for authentication.
What does MAPI stand for in the context of email?
Messaging Application Programming Interface.
MAPI is used by Microsoft Office Outlook to connect to Exchange servers for email management.
What type of cable is typically used to connect a mobile device to a charger?
A mini-USB cable.
Other options include USB-C and micro-USB cables.
What are common examples of wearable devices?
- Smartwatches
- Fitness monitors
- Smart headsets
These devices often collect data and connect to other internet-connected devices.
What is the main purpose of a GPS?
To provide satellite-based navigation.
GPS satellites transmit signals to Earth for location tracking.
What is a PIN?
A PIN is often a number but can also be a numeric code or passkey.
How is a PIN stored?
The PIN is stored using pairing services, so it does not have to be entered the next time the device tries to connect.
What does the email structure rely on?
The email structure relies on email servers and email clients.
What software is required for email servers?
Email servers require email software such as Microsoft Server Exchange.
What is Exchange used for?
