Unlike TCP, UDP is a connectionless protocol that prioritizes speed over reliability. It does not guarantee packet delivery or order, making it ideal for real-time applications.
Practical example: Video calls, online gaming, and live video streams use UDP to minimize latency.
Importance: Its efficiency makes it the best choice for scenarios where a small data loss does not significantly impact the user experience.
4. IPv4/IPv6 (Internet Protocol Versions 4 and 6)
These protocols are responsible for addressing and routing indonesia telegram data data packets across networks. IPv4 , with its 32 bits, is gradually being replaced by IPv6 , which uses 128 bits and allows for an almost infinite number of addresses.
Practical example: IPv4 still powers most of today's networks, but IPv6 is essential to support the expansion of IoT devices.
Importance: IPv6 is key to ensuring that future applications can operate in a world with billions of connected devices.
5. WebSocket
WebSocket allows real-time, two-way communication between client and server. Unlike HTTP, which requires multiple requests and responses, WebSocket establishes a persistent connection.
Practical example: Real-time chat applications, such as Slack, and financial trading platforms use WebSocket to update data instantly.
Importance: It is essential to improve the speed and efficiency of interactive applications that require frequent updates.
6. WebRTC (Web Real-Time Communication)
WebRTC facilitates real-time communication directly between browsers, making it ideal for audio, video, and data transfer applications.
Practical example: Video calls in applications like Google Meet or Zoom are based on WebRTC.
Importance: Allows efficient and secure transmission without the need for intermediate servers.
7. DNS (Domain Name System)
DNS acts as the phone book of the Internet, translating human-readable domain names (such as www.google.com) into machine-readable IP addresses.
Practical example: When you type a domain into your browser, DNS translates it into the IP address of the corresponding server.
Importance: Without DNS, users would have to remember IP addresses, which would be impractical for everyday browsing.
8. MQTT (Message Queuing Telemetry Transport)
MQTT is a lightweight protocol designed for low-bandwidth environments such as IoT devices. It facilitates communication between multiple devices using a publish/subscribe model.
Practical example: In home automation systems, such as those that control smart lights and thermostats, MQTT sends messages between devices.
Importance: Its efficiency makes it ideal for networks of sensors and connected devices.
9. SSH (Secure Shell Protocol)
SSH is a protocol used to securely access and execute commands on remote devices. It protects connections using encryption.
Practical example: System administrators use it to access servers and perform configurations remotely.
Importance: It is vital to manage cloud servers and ensure the security of remote operations.
10. DHCP (Dynamic Host Configuration Protocol)
DHCP automates the assignment of IP addresses to devices on a network, making it easy to connect without manual configuration.
Practical example: When you connect to a Wi-Fi network, DHCP automatically assigns an IP address to your device.
Importance: Simplifies network management and ensures that devices have proper network configurations.
11. ICMP (Internet Control Message Protocol)
ICMP is used by network devices to diagnose connectivity problems and verify whether a host is reachable.
Practical example: The ping command uses ICMP to test connectivity between two devices.
Importance: It is an essential tool to identify network problems and ensure optimal operation.
12. ARP (Address Resolution Protocol)
ARP converts IP addresses into MAC addresses, which are necessary for devices on a local network to communicate.
Practical example: If your computer needs to send data to another device on the same network, it uses ARP to find the corresponding MAC address.
Importance: It is crucial for communication within local networks.
