Lesson 4 - Chapter 4: Creating and Using a LAN Flashcards
What are the 7 basic steps to setup and use a home/small office LAN?
- Connect
- Confirm
- Configure
- Configure
- Share
- Set up
- Browse
- Connect all the NICs to the switch/router
- Confirm that each PC has network connectivity
- Configure workgroup or domain settings
- Configure each PC’s file and printer-sharing security settings
- Share folders and printers from individual PCs
- Set up each PC to use network-shared printers or file servers
- Browse the available network shares using File Explorer
What 2 options do you have to install NICs?
- Install PCIe NICs
- Connect USB-based NICs
What’s the first thing you should do when setting up a LAN?
Make sure each PC has a NIC installed in it and drivers needed
(download drivers from the manufacturer’s website or from media that came with the NIC)
Your network needs a __ __ __ which can be either a ___ or a _____
Your network needs a central connection point which can be either a switch or a router
What network device can you use if no traffic will be leaving the network (will just be between local PCs)?
a switch for the central connection point
What is a consumer-grade router sometimes called?
a broadband router
(because people purchase one to share broadband Internet)
If just one of the PCs in the LAN will connect wirelessly, you NEED to have a ___ ____
wireless router (they support wired AND wireless connections)
What cable is a safe choice to connect the NIC to the switch or router?
Cat 6
What should you make sure to do when connecting each NIC to the switch/router?
Make sure you connect each cable to one of the regular RJ-45 ports, not the special ports (WAN, Uplink, Internet ports)
What is the Internet port on the router/switch for?
To run a cable from the broadband connection box connected to that port on the broadband router so all PCs on the network can share the Internet service
Do you need to do anything manually in order for all the PCs to get an Internet connection?
Not if you have all physical connections made and a router. All PCs should get Internet access automatically.
What are link lights?
the LED status indicator on most desktop NICs that shows the state of the NIC’s link to whatever’s on the other end of the connection
What’s another way to check for network connectivity if you don’t have a router and Internet access?
look for link lights on the NICs
(NICs have between 1-4 different link lights)
Besides NICs, what else has link lights? (2)
switches and routers
If a PC can’t access a network, always check what first?
On A+
the NIC’s LEDs (link lights)
Multispeed devices usually have a link light that tells you what?
the speed of the connection
What’s the difference between orange link lights and green link lights?
Orange link lights signify slower connection speeds (10BaseT or 100BaseT)
versus a port connected to a Gigabit NIC = green light
What does a link light look like when there isn’t a problem? What about when there is a connection problem?
No problem = steady light
Problems = flickering, blinking, off
Besides link lights, what other lights are there?
activity lights
What are activity lights? What does it look like when it’s operating normally?
turns on when the NIC detects network traffic making an intermittent flickering when operating normally
How do link lights and activity lights work together?
Link light tells you that you’re connected, so you test it by trying to copy a file to create network traffic to see if the activity light flickers
Is there a standard that governs how NIC manufacturers use their lights?
No, you will have to take a moment to figure out what each one means
(but functions are always the same: link, activity, speed)
What does a solid green light mean? A flashing green light? No green light? Flashing amber light? (4)
On A+
- Solid green = connectivity
- Flashing green = intermittent connectivity
- No green light = no connectivity
- Flashing amber light = collisions on the network (sometimes is okay)
A network can be either what 2 things?
- peer-to-peer (a workgroup)
- client/server (a domain)
a workgroup is like a home or small office network
What is a workgroup?
a group of networked PCs on the same network
(the multiple PCs in a LAN basically, all connected to the same central connection point like a switch/router)
Why is a workgroup called peer-to-peer?
because there aren’t any servers, only clients (hosts) and each of the clients is equal
When you first set up a network among Windows PCs, what is it by default?
a workgroup
How do you change the name of a workgroup?
Control Panel > System and Security > System > Advanced System Settings > Computer Name > Change
(Advanced System Settings > Opens System Properties (Startup and Recovery, Remote, Virtual Memory, etc)> Computer Name)
What do domains require to control access to the network’s resources?
a specific server
(tracks each user, resource, and what each user can do to each resource)
Larger networks that need more control use what?
domains
Workgroups lack centralized control over the network, and are ideal for smaller networks with fewer than ___ clients
ideal for fewer than 10 clients
(fewer users, connections, security concerns)
To use a domain on a network of Windows machines, you must have a computer with what?
You need a computer running a version of Windows Server
What is Windows Server?
A more expensive, different, and more powerful version of Windows
How do you create a domain?
An admin creates a domain on the Windows Server system [which creates the domain controller (DC)]
What is a domain controller (DC)?
an admin uses the system with Windows Server to create a domain which becomes the DC
After an admin creates the DC, what else do they create? What are they called?
The admin creates new user accounts on the DC called domain accounts
Once a domain is setup, does each PC join automatically?
No, once a network is set up as a domain, each PC on the network needs to join the domain
(which kicks the PC out of the previous workgroup)
How do you connect the PC to a domain?
(Advanced System Settings) > System Properties > Computer Name > Network ID
How is logging in different when logging into a domain versus a workgroup?
When you log into a computer when using a domain, you’re not logging into that actual computer you’re logging directly on to the domain
(all user accounts are stored on the domain controller remember!)
A lot of domains can look like Web addresses. How do you log onto a domain named totalhome.local as the user Fred?
you use \
totalhome.local\Fred
What is the biggest benefit to using a domain?
You can log onto any computer on the domain using the same domain account (known as single sign-on)
(You don’t have to set up separate copies of your account on each computer!)
Where do you go to check folder and printer sharing options?
Settings > Network and Internet > Network and Sharing center > Change advanced sharing settings
Once folder sharing is enabled, how do you share one?
Right click folder in File Explorer > Properties > Sharing tab > Share
Once printer sharing is enabled, how do you share it?
Settings > Devices > Printers & Scanners > Printer Name > Manage > Printer Properties > Sharing tab
How do you connect your PC to a network-shared printer?
Settings > Devices > Printers & Scanners > Add Device
