what is a network a network is a group of devices that are connected in such a

00:17.960 --> 00:22.920
manner that they can share information and resources with each other to create

00:22.920 --> 00:27.120
a network we must have a number of basic components such as network devices

00:27.120 --> 00:33.160
network media network interfaces and the network protocol network Devices we

00:33.160 --> 00:36.800
talk about network Devices we may just think about a group of computers

00:36.800 --> 00:41.960
connected together but the network can also include other items such as servers

00:41.960 --> 00:47.880
printers game consoles such as the ps4 mobile phones and devices such as the

00:47.880 --> 00:51.880
Amazon Echo also known as a voice controlled intelligent personal

00:51.880 --> 00:57.080
assistant generally speaking we call these devices nodes or hosts the

00:57.080 --> 01:02.000
network devices must be connected to each other in somewhere the connection

01:02.000 --> 01:05.760
can be in the form of copper wire communicating through electrical signals

01:05.760 --> 01:10.800
fiber optic cables communicating through light pulses or a wireless connection

01:10.800 --> 01:15.320
using radio waves the cables or signals used to connect the host to the network

01:15.320 --> 01:20.120
refers to a state in network media or medium
