Requirements and constraints for network system design


1. Describe a network card and why it is considered a network system

Network Card

Is a piece of computer hardware that is designed to allow computers to communicate
and connect over a network.

Network cards provide network connections and can communicate with one another
over the same network using a network switch, or when two computers are directly
connected

Types of network cards:

Wireless network cards

USB network adapters

Typical network cards

Why a network card is a network system

A network card is a network system because it is a network device whereby a
network system is a network device (network card)

It inputs, processes, stores and outputs information.

2.

Network protocol

 Set of rules that determine how data is transmitted between different devices
in the same network
 Allows connected devices to communicate with each other, regardless of any
differences in their internal processes, structure, or design.
 Define the methods and mechanisms necessary to achieve reliable
communication between two devices
 Network protocols define methods with which data units are encoded for
transmission and methods for regulating the flow of information between
