Takeaways

• 😀 The internet plays a significant role in various aspects of life, including business, education, social media, governance, and healthcare.
• 😀 Internet allows global communication and information access, removing boundaries related to time and geography.
• 😀 The concept of the internet was introduced in 1962 by Joseph Cher Le Leader with a vision of connecting computers globally to access data and programs.
• 😀 ARPANET, developed in the 1970s, was the first system that allowed electronic mail (email) to be sent, a precursor to modern internet services.
• 😀 Networks are classified into types like **LAN (Local Area Network)**, **MAN (Metropolitan Area Network)**, **WAN (Wide Area Network)**, and **Intranet**, based on the area they cover.
• 😀 **LAN** connects computers in a small, localized area (e.g., offices or buildings), while **WAN** spans a much larger area, potentially across continents.
• 😀 **Wireless Networks** use electromagnetic waves for data transmission, offering flexibility and speed in installations compared to wired networks.
• 😀 The internet connection speed is crucial for determining the quality of browsing, uploading, and downloading. You can test your speed using websites like speedtest.net.
• 😀 An **ISP (Internet Service Provider)** is essential for providing internet access. In Indonesia, an example is Telkom Speedy.
• 😀 Devices can be connected to the internet via LAN, Wi-Fi, Bluetooth, USB tethering, or even satellite, each offering different benefits and use cases.
• 😀 **Tethering** allows a mobile device to act as a hotspot to share internet with a computer or other devices, providing flexibility in internet access.

Q & A

What is the main purpose of this video?

What are the learning objectives of this video?

The learning objectives include: 1) Understanding how to connect a computer to the internet and how it works, 2) Learning to connect a computer using wireless LAN (Wi-Fi), and 3) Learning to connect a computer using tethering (via phone, Bluetooth, or USB).

What is the meaning of 'internet' as described in the video?

The internet is described as a system of interconnected computer networks that allows for communication and data exchange between computers on a global scale.

What historical figure is credited with the early development of the internet?

Joseph Cher Leiner is credited with developing the concept of the 'Galactic Network' in 1962, which eventually led to the creation of the internet.

What is the role of ARPANET in the development of the internet?

ARPANET, created by ARPA (Advanced Research Projects Agency) in 1972, is considered the precursor to the modern internet. It enabled computers to communicate with each other over a network.

What is the difference between a server and a client in a computer network?

A server manages and shares resources in a network, such as data and services, while a client is a computer that receives services from the server.

What are the main benefits of using a computer network?

The main benefits of computer networks include resource sharing, high reliability, cost savings, and improved communication.

What are the different types of computer networks based on physical connectivity?

The two main types of networks based on physical connectivity are: 1) Wired networks (using cables) and 2) Wireless networks (using electromagnetic waves, such as Wi-Fi).

What are the different types of computer networks based on their area of coverage?

The types based on area coverage are: 1) LAN (Local Area Network), which covers a small area, 2) MAN (Metropolitan Area Network), which covers a larger city area, 3) WAN (Wide Area Network), which covers large geographic areas like countries or continents, and 4) Intranet, which is a private network within an organization.

What is the role of ISP in internet connectivity?

ISP (Internet Service Providers) are companies that provide access to the internet. In Indonesia, examples of ISPs include Telkom and Speedy. They supply the connection through various technologies such as fiber optics, DSL, and more.
