Network Hardware
Overview
How does one device find another among the billions connected to the world? Every networked computer relies on a small set of hardware and addresses working together: a card that physically connects it, a permanent factory address, a network-assigned address, and a device that forwards data to exactly the right place.
In this lesson you will learn what a network interface card does, the structure and purpose of a MAC address, the two kinds of IP address (IPv4 and IPv6) and how they differ, and the central role of the router in directing data and connecting a local network to the internet.
Objectives
- 1 Understand that a computer needs a network interface card (NIC) to access a network
- 2 Understand what is meant by, and the purpose of, a media access control (MAC) address, including its structure
- 3 (a) Understand what is meant by, and the purpose of, an internet protocol (IP) address (b) Understand that there are different types of IP address
- 4 Describe the role of a router in a network
