Cara Kerja Internet (BASIC TCP/IP)

Summary

In today's digital age, the internet plays a crucial role in connecting various devices like phones, computers, and laptops. This interconnected network relies on protocols such as TCP/IP to ensure smooth data transmission between devices. Each device is assigned an IP address by Internet Service Providers (ISPs), allowing them to be identified on the internet. When data is sent, it follows a dynamic route through routers and Wi-Fi towers, ensuring that the message reaches its destination, even if it has to pass through various networks or countries. The process involves multiple stages of routing and adjustments to ensure continuous communication.

Takeaways

• 😀 The internet is a network that connects various devices, like smartphones, computers, and laptops, allowing communication between them.
• 😀 The internet is also referred to as an interconnected network, or 'jaringan yang saling terhubung' in Indonesian, meaning devices can connect with each other.
• 😀 Internet connections can be made through cables (like fiber optics) or wirelessly (e.g., Wi-Fi).
• 😀 Devices in the internet network follow protocols, one of which is TCP/IP (Transmission Control Protocol and Internet Protocol), essential for data transmission.
• 😀 TCP/IP is the main protocol used for data transmission, enabling devices to recognize and communicate with each other.
• 😀 An IP address is a unique identifier for a device in the network, much like a physical address for a house.
• 😀 IP addresses are provided by Internet Service Providers (ISPs) such as Indihome, Telkomsel, Biznet, and Indosat.
• 😀 When a device receives an IP address, it can be used as an identity for the device to be recognized on the internet.
• 😀 Data sent over the internet is not directly sent from the sender to the receiver; it travels through multiple routes and devices (like routers or Wi-Fi towers).
• 😀 TCP/IP acts as the 'courier' for internet data, ensuring it follows the correct routes and reaches its destination, even if some routes or devices encounter issues.
• 😀 If there are problems with a tower or router, the data packet will be rerouted through alternative routes, ensuring the message reaches its final destination.
• 😀 Data packets sent over the internet are flexible and dynamic, meaning they can travel through different routers or towers, even across different countries or islands, to reach the intended recipient.

Q & A

What is the internet, and how does it function?

The internet is a global network that connects devices like computers, smartphones, and other devices, allowing them to communicate and share information. It functions as an interconnected network where all devices follow specific protocols to exchange data.

What is meant by the term 'interconnected network'?

An interconnected network refers to a system where multiple devices, such as phones, computers, and laptops, are linked together, enabling communication and data sharing between them.

What are the two main types of internet connections?

Internet connections can be either wired or wireless. Wired connections use cables such as fiber optics, while wireless connections use technologies like Wi-Fi to transmit data without the need for physical cables.

What role do protocols play in the functioning of the internet?

Protocols, like TCP/IP, are essential in ensuring that devices can recognize and communicate with each other. They establish the rules for transmitting data over the internet, ensuring that the data is correctly sent and received.

What is TCP/IP, and why is it important?

TCP/IP stands for Transmission Control Protocol and Internet Protocol. These protocols are responsible for ensuring that data is properly sent across networks and that devices on the internet can communicate with one another reliably.

What is an IP address, and what purpose does it serve?

An IP address is a unique identifier assigned to each device on a network, serving as its address on the internet. It helps devices to recognize each other and ensure data is sent to the correct destination.

Where does an IP address come from?

An IP address is provided by an Internet Service Provider (ISP). The ISP assigns an IP address to each device that connects to the internet, allowing it to be identified on the network.

How is data routed on the internet?

When data is sent over the internet, it is not sent directly from the sender to the receiver. Instead, it passes through multiple routers and network devices, which determine the best route for the data to reach its destination.

What happens if there is an issue with a router or tower during data transmission?

If a router or tower encounters an issue, the network automatically reroutes the data through alternative paths, ensuring that the message or data can still reach its destination, even if it needs to travel through different towers or routers.

How does data travel between two distant locations, such as from Bandung to Surabaya?

When data is sent from one location to another, such as from Bandung to Surabaya, it may pass through various intermediate routers or towers. These routers dynamically choose the best route, and the data might even travel through routers in different regions or countries before reaching its destination.
