Network protocals

Network protocols are standardized rules or conventions used to enable communication between
devices in a computer network. These protocols define how data is formatted, transmitted,
routed, and received across the network. They ensure that devices can understand and interpret
each other's communications, regardless of their underlying hardware or operating systems. Here
are some key network protocols categorized by their roles:

Transmission Control Protocol/Internet Protocol (TCP/IP)

TCP/IP is the fundamental protocol suite of the Internet and most modern networks. It consists of
several protocols, including:

1. Internet Protocol (IP):

o Responsible for addressing and routing packets of data so they can travel across
networks.
o Versions include IPv4 and IPv6.
2. Transmission Control Protocol (TCP):
o Provides reliable, ordered, and error-checked delivery of data packets between
devices.
o Ensures that data transmitted from one endpoint to another arrives intact and in
order.
3. User Datagram Protocol (UDP):
 o Offers a connectionless protocol for sending datagrams over a network.
o Suitable for applications where speed and efficiency are more important than
reliability (e.g., real-time communication, streaming media).

Ethernet

Ethernet is a widely used LAN technology that defines how network devices can format and
transmit data over a physical medium, such as twisted-pair cables or fiber optics. Key Ethernet
protocols include:

1. IEEE 802.3: Defines the standards for Ethernet networks, including frame formats,
addressing schemes, and collision detection.
2. Ethernet II (DIX Ethernet): One of the original Ethernet frame formats, specifying the
structure of Ethernet frames and the use of MAC addresses.

Address Resolution Protocol (ARP)

ARP is used to map IP addresses to MAC addresses within a local network segment. When a
device wants to send data to another device on the same network, ARP resolves the IP address of
the destination device to its corresponding MAC address.

Domain Name System (DNS)

DNS translates domain names (e.g., www.example.com) into IP addresses that computers can
use to locate and communicate with each other on a network. It allows users to access websites
and other Internet resources using easy-to-remember domain names rather than IP addresses.

Dynamic Host Configuration Protocol (DHCP)

DHCP automates the assignment of IP addresses, subnet masks, default gateways, and other IP
parameters to network devices. DHCP servers dynamically allocate IP addresses to devices when
they join the network, simplifying network administration and management.

Hypertext Transfer Protocol (HTTP) and HTTPS

HTTP is a protocol for transferring hypertext requests and information between servers and
clients. HTTPS (HTTP Secure) adds encryption to HTTP, ensuring secure communication over
the Internet, commonly used for secure transactions and data exchange.

File Transfer Protocol (FTP) and Secure FTP (SFTP)

FTP is a standard protocol for transferring files between a client and a server on a network. SFTP
(SSH File Transfer Protocol) provides secure file transfer capabilities over SSH-encrypted
connections, ensuring data confidentiality and integrity.

Simple Mail Transfer Protocol (SMTP) and Post Office Protocol (POP3/IMAP)

SMTP is used for sending email messages between servers. POP3 (Post Office Protocol version
3) and IMAP (Internet Message Access Protocol) are protocols used by email clients to retrieve
email messages from a server.

Virtual Private Network (VPN) Protocols

VPN protocols establish secure and encrypted connections between devices over a public
network (e.g., the Internet). Common VPN protocols include:

1. Point-to-Point Tunneling Protocol (PPTP): Provides encrypted tunnels for VPN

connections, although it is considered less secure due to vulnerabilities.
2. Layer 2 Tunneling Protocol (L2TP): Combines features of PPTP and Layer 2
Forwarding (L2F) to create secure tunnels.
3. Internet Protocol Security (IPsec): Suite of protocols used to authenticate and encrypt
IP packets in a VPN.

for long-range, low-power IoT applications. It operates in unlicensed radio bands (e.g., 868 MHz
in Europe, 915 MHz in North America) and enables long-distance communication between IoT
devices and gateways. LoRaWAN is suitable for applications requiring extended range and
battery-powered devices.

Note
