    Under normal conditions, how many milliamps of current could cause cardiac arrest?

    • 50

    • 40

    • 20

    • 10

    Correct Answer
    A. 50
    Explanation
    Under normal conditions, a current of 50 milliamps could cause cardiac arrest. Cardiac arrest occurs when the electrical activity of the heart becomes disrupted, leading to the heart stopping. At 50 milliamps, the electrical current can interfere with the heart's normal rhythm and potentially cause it to stop. Lower currents, such as 40, 20, or 10 milliamps, may still cause harm but are less likely to result in cardiac arrest.

    Which network uses Carrier Sense Multiple Access/Collision Avoidance (CSMA/CA) to avoid collisions while transmitting data?

    • Local area network (LAN).

    • Wide area network (WAN).

    • Metropolitan area network (MAN)

    • Wireless local area network (WLAN).

    Correct Answer
    A. Wireless local area network (WLAN).
    Explanation
    Wireless local area networks (WLANs) use Carrier Sense Multiple Access/Collision Avoidance (CSMA/CA) to avoid collisions while transmitting data. CSMA/CA is a protocol used in wireless networks to prevent multiple devices from transmitting data at the same time, which can cause collisions and data loss. With CSMA/CA, devices listen for other devices transmitting data and wait for a clear channel before sending their own data. This helps to ensure that data transmissions are successful and collisions are avoided in WLANs.
