Network Fundamentals

A network protocol defines the rules and procedures for communication between devices on a network, ensuring that data is transmitted and received correctly.

In a star network, all devices are connected to a central hub or switch, which serves as the central connection point for data transmission.

A router's primary function is to forward data packets between different networks, determining the best path for data transmission based on network traffic and routing protocols.

DHCP (Dynamic Host Configuration Protocol) is responsible for assigning IP addresses, subnet masks, and other network configuration parameters to devices on a network automatically.

A firewall is a network security device that monitors and controls incoming and outgoing network traffic, blocking unauthorized access and protecting the network from security threats.

In a mesh topology, each device is connected to every other device on the network, creating multiple paths for data transmission and providing redundancy.

A network switch is a networking device that connects devices on a network, allowing them to communicate with each other and share resources.

FTP (File Transfer Protocol) is a network protocol specifically designed for transferring files between devices on a network, allowing users to upload, download, and manage files remotely.

A network mask is used to determine which part of an IP address represents the network address and which part represents the host address, allowing devices to identify the network they belong to.

SMTP (Simple Mail Transfer Protocol) is a network protocol specifically designed for sending email messages between devices on a network, allowing users to send and receive emails.

A gateway is a networking device that connects different networks, allowing data packets to be forwarded between them, enabling communication between devices on different networks.

HTTP (Hypertext Transfer Protocol) is a network protocol used for transferring web pages and other resources between devices on a network, allowing users to access and browse the internet.

A DNS server is responsible for translating domain names, which are human-readable website addresses, into IP addresses, which are numerical addresses used by devices to communicate on a network.

RTP (Real-time Transport Protocol) is a network protocol specifically designed for streaming audio and video content over a network, ensuring smooth and reliable transmission of multimedia data.

A proxy server acts as an intermediary between clients and servers, receiving requests from clients and forwarding them to servers, and returning responses from servers to clients, providing security and performance benefits.
