Networking 2.7 - Internet Connection & Network Types

Question 1

six different types of networks

Answer 1

Local area network (LAN)

Wide area network (WAN)

Personal area network (PAN)

Metropolitan area network (MAN)

Storage area network (SAN)

Wireless local area network (WLAN)

Question 2

LAN

Answer 2

local area network (LAN) was created to connect computers in a single office or building.

Question 3

WAN

Answer 3

wide area network (WAN) includes networks outside the local environment and can also distribute resources across great distances. Generally, it’s safe to think of a WAN as multiple dispersed LANs connected.

Question 4

PAN

Answer 4

personal area network (PAN) is a very small-scale network designed around one person within a very limited boundary area. The term generally refers to networks that use Bluetooth technology.

Question 5

MAN

Answer 5

metropolitan area network (MAN), which is bigger than a LAN but not quite as big as a WAN.

Question 6

SAN

Answer 6

storage area network (SAN) is designed for optimized large-scale, long-term data storage. A network (or network segment) that holds nothing but networked storage devices, whether they be network-attached storage (NAS) hard drives or servers with lots of disk space dedicated solely to storage.May include huge data files or videos, is sent to a specific network or network segment, relieving traffic on other network segments.

Question 7

WLAN

Answer 7

Wireless LAN - Wireless clients on a network typically access the network through awireless access point (WAP). The WAP may connect wirelessly to another connectivity device, such as a wireless router, but more likely uses a wired connection to a router or switch.

Question 8

IEEE 802 Standards

Answer 8

802.11ax (Wi-Fi 6), 802.11ac (Wi-Fi 5), or 802.11n wireless networking (wi-fi 4)

Network rules that govern who communicates, when they do it, and how they do it.

IEEE = Institute of Electrical and Electronics Engineers

Two sublayers:
- The LLC = Logical Link Control sublayer manages data link communications
- MAC = Media Access Control sublayer watches out for data collisions and manages physical hardware addresses (MAC addresses)

Question 9

VLAN

Answer 9

Managed switch - increases security & reduces traffic because can be isolated

Question 10

Internet connection types (6)

Answer 10

satellite
fibre optic
cable
DSL
Cellular
WISP = wireless internet service provider

Question 11

Satellite =

Answer 11

wireless internet beamed down from ISP satellites orbiting the Earth.

Question 12

Fibre =

Answer 12

Broadband (up to 10 Gbps)

Question 13

Cable =

Answer 13

Ethernet, RJ-45, Cat 5e

Question 14

DSL =

Answer 14

Landline, RJ-11

Question 15

Cellular =

Answer 15

Cell phone
Radio frequencies from cell tower

Question 16

WISP

Answer 16

Wireless internet service provider

Question 17

What is the difference between Wi-Fi and wireless Internet?

Answer 17

Wi-Fi is a wireless connection created from a wired network using a wireless router or access point = wireless connectivity for DSL, satellite internet, and fiber optics.
Wireless Internet = Cellular Wireless

Question 18

A controller area network (CAN) replaces

Answer 18

replaces bulky wiring systems, reducing weight and cost; used in industrial applications, originally in automotive systems.
