◉ Preamble, start frame delimiter, destination mac address, source
address, length/type, data, pad, and frame check sequence. Answer:
The structure of the Ethernet frame
◉ An alternating pattern of 1s and 0s used for synchronization
Answer: The preamble of an Ethernet packet
◉ A binary 8 bit sequence of 10101011 that indicates the start of the
frame Answer: The start frame delimiter of an Ethernet packet
◉ The MAC address associated with the network adapter or
Ethernet network interface card (NIC) Answer: The destination and
source MAC addresses of an Ethernet packet
◉ An indication of the number of bytes in the data field if this value
is less than 1500, or if the number is greater than 1500, and
indication of the type of data format such as IP and IPX Answer: The
length/type of the Ethernet packet frame
,◉ The variable length of data being transferred from the source to
the destiontion Answer: The data of the Ethernet packet frame
◉ A field used to bring the total number of bytes up to the minimum
of 46 if the data field is less than 46 bytes Answer: The pad of the
Ethernet packet frame
◉ A 4 byte CRC value used for error detection Answer: The frame
check sequence of the Ethernet packet frame
◉ What is the minimum length of the Ethernet frame from
destination MAC address through the frame check sequence?
Answer: 64 bytes
◉ a device that relays the wireless signals from an access point or
wireless router into areas with a weak signal or no signal at all
Answer: range extender
◉ Where can range extenders be used to improve connectivity?
Answer: Stores, warehouses, and public places using hotspots
◉ a limited geopgraphic area that provides wireless access for the
public Answer: hot spot
, ◉ What basic steps can help secure a wireless home network?
Answer: "1. Change the default factory password
2. Change the default SSID
3. Turn encryption on
4. Turn off the SSID broadcast
5. Enable MAC address filtering"
◉ How should a default password on a wireless device be reset?
Answer: using a combination of alphanumeric characters
◉ the name used to identify your network and is used by your
access point or wireless router to establish an association Answer:
SSID
◉ Service Set Identifier Answer: SSID
◉ How many characters can the SSID be? Answer: 32
◉ What does the turning off the SSID broadcast of your access point
or wireless router in your wireless home network do? Answer:
prevents the wireless system from broadcasting SSID
