Long answer

1. What is connectivity?

"The ability of differente devices and systems to establish a connection and communicate with each other."

2. What are the steps involved in establishing connectivity between devices?

  1. Device identification
  2. Network infrastructure
  3. Data transmission
  4. Routing
  5. Protocols

3. Why is connectivity important in today's interconnected world?

Because it enables and powers "data transfer, collaboration, and access to inormation", al in the name of Mammon.

4. What is the role of protocols in connectivity?

They determine the way in which data is transmitted and received across the network.

5. Name a commonly used protocol for internet communication?

TCP/IP

6. What is the purpose of a router in a network?

They redirect the flow of data through the analysis of packet headers, routing them toward their intended direction.

7. How does a switch contribute to network communication?

They 'multiply' the amount of data flows that a network can admit, acting as a 'switch' between many different wired connections.

8. What is the function of a modem in connectivity?

They convert analog data (coming from the wired ISP-provided connection) into digital information and vice-versa.

9. What are some exmples of wireless connectivity technologies?

  • Wi-Fi
  • Bluetooth
  • Cellular networks:
    • 3G
    • 4G
    • 5G

10. Define Internet of Things (Iot) and explain its reliance on connectivity

It's this thing where a bunch of day-to-day objects are turned into networked devices for absolutely no reason. Since to be 'smart' they need to be connected to a network, they rely on connectivity.

11. What are some commonly used protocols for web communication?

  • TCP/IP
  • HTTP/HTTPS
  • Ethernet
  • Wi-Fi
  • Bluetooth

12. How does Ethernet contribute to wired connectivity?

It enables wired connections within LANs.

13. Name a wireless protocol used for connecting smartphones and IoT devices

Bluetooth

14. What is the role of a wireless access point (WAP) in a network?

Acting, as their name suggests, as access points to devices which use a wireless connection in order to communicate.

15. Differentiate between a wide area network (WAN) and a local area network (LAN)

A LAN is usually limited to the area occupied by a building or a small enclosed facility. A WAN is made up of LANs, and its range can be up tothat of a city.

  1. Faster data transmission
  2. Lower cost
  3. More secure connections
  4. Freedom of movement

7. Which protocol is commonly used for short-range wireless connections between devices like smartphones and IoT devices?

  1. TCP/IP
  2. Ethernet
  3. Bluetooth
  4. HTTP

8. Which type of connectivity enables access to a wide range of services, applications and information?

  1. Wired connectivity
  2. Local Area Network (LAN)
  3. Personal Area Network
  4. Internet connectivity

9. What is the purpose of a modem in connectivity?

  1. Creating wireless connections
  2. Directing data traffic between devices
  3. Converting digital data into analog signals
  4. Facilitating data transmission over Ethernet cables

10. What differentiates a Wide Area Network (WAN) from a Local Area Network? (LAN)?

  1. WAN covers a larger geographical area than LAN
  2. WAN provides faster data transmission than LAN
  3. WAN uses wireless connectivity, while LAN uses wired connectivity
  4. WAN is more secure than LAN
