QUESTION: 5

What is the typical range of a wireless body area network (WBAN)?

1-2 meters
10 square meters
10 centimeters
10 meters

Answer(s): A

Explanation:

WBAN Range: Wireless Body Area Networks (WBANs) specialize in short-range communication around the human body. Typical ranges fall within 1-2 meters.
Purpose: This range is designed to:
Connect sensors monitoring health metrics.
Transmit data to a central coordinator device (e.g., smartphone). Minimize interference potential with other wireless networks.

QUESTION: 6

What software is typically stored in ROM and is used to initialize a device?

Firmware
Application
Container
Service

Answer(s): A

Explanation:

Firmware Definition: Firmware is a type of software embedded in hardware devices. It provides low- level instructions that control the basic operations and initialization of the device. ROM Storage: Firmware is typically stored in Read-Only Memory (ROM) or other forms of non- volatile memory, meaning it persists even when the device is powered off.
Functions:
Booting: Initiates the hardware and loads the operating system. Hardware Control: Provides an interface between the hardware and the operating system. BIOS: The firmware on PCs is often referred to as BIOS (Basic Input/Output System).
