Fundamentals of computer networking Introduction

Types The majority of routers use the BGP to share routing information. The type of information shared depends on the usage of the router and the functions they use. There are several distinct classifications or types of routers available to service different network needs.

Access routers Distribution routers Edge routers Core routers

Two Azure options can help with routing and managing network traffic.

A network topology describes the physical composition of a network. Let's look at four topologies you can choose from when you design a LAN. They are:

Bus Ring Mesh Star

There are several network standard-compliant devices that make up the structure of your networks. Depending on the network's size, you might use several of these devices to build the backbone of your network. These devices are:

Repeaters Hubs Bridges Switches Routers FYI: Nearly all of these devices depend on a media access control or an Internet Protocol (IP) address to deliver data on the network

What does a router do?

A router is an essential part of your network. A router connects different networks and also connects to the internet.

What is the primary purpose of a hub

Hubs offer the simplest form of network. They allow multiple Ethernet-based network-enabled devices to communicate with each other.

What is the principal difference between hub routing and switch routing?

Hub routing sends all packets to all connected devices. Switch routing sends packets to specific devices.

What are network standards used for?

Network standards are designed to ensure that hardware and software made by different vendors work seamlessly together.

Networks vary in size, shape, and usage. To make it easier to identify different network types, they're categorized into one of the following network categories:

Personal area networks Local area networks Metropolitan area networks Wide area networks
