1
00:00:06,480 --> 00:00:08,970
- Welcome to module two, networking.

2
00:00:08,970 --> 00:00:12,120
The module is broken
down into eight lessons.

3
00:00:12,120 --> 00:00:15,540
We'll begin with an introduction
to computer networking.

4
00:00:15,540 --> 00:00:18,360
After that, it's ports and protocols.

5
00:00:18,360 --> 00:00:20,910
Then we'll move on to networking devices,

6
00:00:20,910 --> 00:00:23,760
and focus in on SOHO Networks.

7
00:00:23,760 --> 00:00:26,820
Next, we'll cover wireless
networking protocols.

8
00:00:26,820 --> 00:00:30,090
And after that, we'll
move into networked hosts,

9
00:00:30,090 --> 00:00:33,660
including the various types
of servers you'll encounter.

10
00:00:33,660 --> 00:00:37,620
Then it's network
configuration and TCP/IP.

11
00:00:37,620 --> 00:00:40,440
We'll round out the
module with network types

12
00:00:40,440 --> 00:00:42,750
and networking tools.

13
00:00:42,750 --> 00:00:44,340
Today, just about all computers

14
00:00:44,340 --> 00:00:46,440
need to be networked together.

15
00:00:46,440 --> 00:00:49,110
The CompTIA A+ networking domain

16
00:00:49,110 --> 00:00:51,780
comprises 20% of the exam,

17
00:00:51,780 --> 00:00:54,450
and you can bet that there
will be plenty of questions

18
00:00:54,450 --> 00:00:57,450
about networking on the A+ exam.

19
00:00:57,450 --> 00:00:59,050
Let's get into the first lesson.
