Study Notes
The Internet Overview
- The Internet is a global network linking millions of entities including businesses, governments, and individuals.
- It enables unprecedented global communication and information sharing, facilitating connectivity and collaboration.
- Originated as ARPANET in September 1969, aimed to connect scientists and ensure functionality despite potential network failures.
- By 1984, ARPANET linked over 1,000 individual computers, evolving into the vast Internet known today.
Connecting to the Internet
- Internet connectivity can be achieved through various methods:
- Wired Connections
- Wireless Connections
Wired Connections
-
Ethernet Cables
- Utilize twisted pairs of wires to transmit data, offering reliable and low-latency connections.
- Common types: CAT5, CAT6, and CAT7 with increasing speeds and bandwidth.
- Ideal for high-demand activities such as online gaming and streaming.
-
Fiber Optic Connections
- Employ thin strands of glass that transmit data as pulses of light, enabling very high speeds and low latency.
- Gaining popularity for both home and business use due to stability over long distances.
-
Setting Up Wired Connections
- Connect an Ethernet cable from the modem to the router, then from the router to the device.
- Most devices automatically configure network settings for easy setup.
Wireless Connections
-
Wi-Fi (Wireless Fidelity)
- Utilizes radio waves for device connectivity, becoming the most common method for home use.
- Different standards (802.11a/b/g/n/ac/ax) provide increasing speeds and range, facilitating high-speed internet and wireless networking.
-
Mobile Data (3G, 4G, 5G)
- Connects devices to the internet through cellular networks.
- 3G offers basic speeds; 4G supports streaming and gaming, while 5G offers very high speeds and low latency, enabling advanced applications.
-
Satellite Internet
- Provides internet access via satellites orbiting the Earth, useful for remote areas.
- Typically has higher latency compared to other options due to the distance signals must travel.
Essential Hardware
-
Modems
- Serve as a bridge between the Internet Service Provider (ISP) and home network, converting signals for device use.
- Commonly provided by the ISP and directly connected to the internet.
-
Routers
- Create and manage a local network within a home, allowing multiple devices to share an internet connection.
- Ensure smooth communication between devices and the internet.
-
Network Interface Cards (NICs)
- Necessary for device connectivity to a network; most modern devices come with built-in NICs for wired and wireless connections.
- External NICs, like USB adapters, are available for additional connectivity options.
