Course
Local Area Networking
Explore the complexities of LAN with this course covering network IDs and subnet masks, router configuration, port forwarding and more.
Course description
Dive deep into the details of Local Area Networking, or LAN, with this course covering the essential topics in this area. Take a look at network IDs and subnet masks, NAT, dynamic IP addressing, port numbers, working with Active Directory, firewall configuration and much, much more. What’s the difference between TCP, UDP and ICMP? And what does LLDP stand for, anyway? Now is the time to learn.
Syllabus
Network Troubleshooting
Video - 00:05:00
A good network tech knows how read symptoms and diagnose a network quickly to enable users to get back to work.
VLANs
Video - 00:07:00
VLANs provide superb control of your LAN but have their own quirks that a good tech understands.
Advanced Router Configuration
Video - 00:06:00
Protocols such as Quality of Service, Universal Plug and Play and Simple Network Management Protocol give extra features to enhance the capabilities of your router.
Port Forwarding
Video - 00:07:00
Port forwarding allows opening specific ports on your NAT-enabled router to provide access to servers behind it.
Windows Firewall
Video - 00:08:00
Unlike the firewall on your router, the Windows software firewall only protects a single system, and it’s important for techs to understand how to use it.
Firewall Configuration
Video - 00:11:00
Setting up a hardware firewall is an obvious first step to making sure your network is well-protected.
Basic Router Configuration
Video - 00:12:00
All routers share some basic configuration steps every tech must know.
Routers
Video - 00:12:00
The CompTIA A+ exams challenge test takers to perform many configurations of a typical home router, but what does a router do for a SOHO network?
Net Command
Video - 00:04:00
The Windows net command, used for everything from querying the network to accessing shares, has so many features that it deserves its own episode.
Windows Sharing with Mac and Linux
Video - 00:07:00
Both Mac and Linux systems know how to use Windows naming functions; the trick is to understand how they do it and to configure them to work with an existing Windows network.
Working with Active Directory
Video - 00:14:00
More advanced Windows networks use domains instead of workgroups, providing powerful services for larger networks.
Working with Workgroups
Video - 00:08:00
Workgroups are simple and provide no security, but they’re a part of every small Windows network.
Windows Naming
Video - 00:08:00
Microsoft introduced a series of naming protocols, some of which predate the internet.
Working with DNS
Video - 00:07:00
There are a few simple tools and procedures to diagnose and repair DNS problems.
Understanding DNS
Video - 00:09:00
To make our lives easier, most TCP/IP networks (and certainly the Internet) use the Domain Naming System (DNS) to apply human-friendly names to systems.
Working with Connections
Video - 00:09:00
A good tech knows how to use common utilities to observe connections and diagnose issues.
TCP, UDP and ICMP
Video - 00:06:00
User Datagram protocol (UDP) and Internet Control Message Protocol (ICMP) both serve important purposes and features that techs need to understand.
Port Numbers
Video - 00:12:00
It’s critical to understand how port numbers do their job and to memorize many special port numbers.
IPv6
Video - 00:07:00
IPv6 adds several benefits over IPv4 and good techs know how to use it in our systems.
Dynamic IP Addressing
Video - 00:10:00
To avoid the nightmare of manually entering IP addresses, smart techs use the Dynamic Host Control Protocol (DHCP) to automatically provide IP addressing to individual hosts.
NAT
Video - 00:07:00
Network Address Translation, or NAT, provides some amazing benefits but also has some serious limitations.
Special IP Addresses
Video - 00:09:00
From loopback to private IP addresses, a good tech understands special reserved addresses as well as when and how to use them.
Network IDs and Subnet Masks
Video - 00:05:00
The first step towards understanding IP addressing flexibility is to understand network IDs and how they interact with a subnet mask to get packets delivered to the right system.
Introduction to TCP/IP
Video - 00:14:00
It’s important to understand IP addressing schemes and to see how TCP and IP work together to make the internet work.
