  • Climate control devices
    4.1.2

Question 2

(Typical Home Network Routers)
Ethernet Ports

Answer 2

These ports are usually labeled Ethernet or LAN

Question 3

(Typical Home Network Routers)
Internet Ports

Answer 3

These ports are used to connect the device to another Network. The internet port connects the router to a different Network than the Ethernet ports. Often to connect to cable or DSL modem in order to access the internet.

Question 4

LAN Wireless Frequencies

Answer 4

The wireless technologies most frequently used in home networks are in the unlicensed 2.4 GHz and 5 GHz frequency ranges.

Question 5

Bluetooth

Answer 5

Operates in the 2.4 GHz band

Question 6

Category 5e

Answer 6

Cable is made up of 4 pairs of wires that are twisted to reduce electrical interference 4.2.2

Question 7

Coaxial cable

Answer 7

It has an inner wire surrounded by tubular insulation layer, that is then surrounded by a tubular conduction shield. Most have an external sheath or jacket. 4.2.2

Question 8

Fiber-optic cable

Answer 8

It can either be glass or plastic. It can be about the size of a human hair and it can carry digital information at a very high speed over long distances. They have very high bandwidths, which enable them to carry very large amounts of data.

Question 9

Standards for Wireless Communication

Answer 9

• Developed to ensure communication among wireless devices.
  
  • Specifies RF spectrum, data rates, transmission methods, etc.
  • Institute of Electrical and Electronics Engineers (IEEE) is the main organization for creating wireless standards.

Question 10

IEEE 802.11 Standard

Answer 10

• Governs Wireless Local Area Network (WLAN) environment.
  
  • Amendments describe characteristics for different wireless communication standards.
  • Wi-Fi collectively refers to technologies using 2.4 GHz and 5 GHz frequency bands.

Question 11

Wi-Fi Alliance

Answer 11

Responsible for testing wireless LAN devices from various manufacturers.
- Wi-Fi logo indicates compliance with standards for interoperability.

Question 12

Evolution of Wireless Standards

Answer 12

• Constant improvement in connectivity and speed of Wi-Fi networks.
  
  • Awareness of new standards is crucial as manufacturers quickly implement them in new products.

Question 13

Home Wireless Network Considerations

Answer 13

• Inquiry about the existence of a wireless network in the home.
  
  • Knowledge of supported standards by the wireless router is essential.

Question 14

Packet Tracer Basic Wireless Settings interface

Answer 14

wireless routers using the 802.11 standards have multiple settings that have to be configured.

Question 15

Network Mode

Answer 15

• Determines the supported technology (e.g., 802.11b, 802.11g, 802.11n, or Mixed Mode).

Question 16

Network Name (SSID)

Answer 16

• Identifies the WLAN; all participating devices must share the same SSID.

Question 17

Standard Channel

Answer 17

• Specifies the communication channel; usually set to Auto for the access point to determine the optimum channel.

Question 18

SSID Broadcast

Answer 18

• Determines if the SSID is broadcast to devices within range; typically enabled by default.

Question 19

SSID

Answer 19

Service set Identifier

Question 20

802.11 Protocol and Throughput

Answer 20

• Increased throughput in wireless network environment based on the 802.11 standard.
  
  • Maximum speeds achieved when all devices support the same 802.11 standard.
  • Access points configured for a specific standard may not connect devices using other standards.

Question 21

Mixed Mode Wireless Network

Answer 21

• Allows devices using any existing Wi-Fi standards.
  
  • Facilitates connection for older devices not supporting the latest standards.

Question 22

SSID in Wireless Networks

Answer 22

• Important for wireless components to connect to the appropriate WLAN.
  
  • Identifies the WLAN to wireless devices (STAs) and defines communication with other devices.
  • SSID broadcast enables automatic discovery of the network; when disabled, manual entry is required on wireless devices.

Question 23

SSID Functionality

Answer 23

• Essential for connecting wireless components to the appropriate WLAN.
  
  • Acts as the name of the network.
  • Wireless routers typically broadcast configured SSIDs by default.

Question 24

SSID Broadcast and Manual Entry

Answer 24

• SSID broadcast allows automatic discovery of the network.
  
  • Disabling SSID broadcast requires manual entry of SSID on devices.

Question 25

Security Considerations

Answer 25

• Disabling SSID broadcasting may make it harder for legitimate clients to find the network.
  
  • Strong encryption recommended to prevent unauthorized access.

Question 26

Wireless Router Settings

Answer 26

• Configurable settings include Network Mode, SSID, Standard Channel, and SSID Broadcast.
