Set File and Folder Sharing
To “share” a file or folder means to make it accessible by users other than the user who created the file or folder.
To share folders and drives (and printers), you must address three components of Windows 7: The Windows Firewall The Network and Sharing Center Sharing individual drives and folders.

Set up the Windows Firewall
Start Control Panel System and Security Windows Firewall.
You turn it on or off by the link in the left pane. To allow a particular program through the firewall,
click the link that says “allow a program or feature through Windows Firewall.”
Take a look at the Program/Feature list. For file sharing, you’ll need “Core Networking” and
“File and Printer Sharing” checked.

Network and Sharing Center
Once the Firewall is set, you need to look at the Network and Sharing Center.
Start Control Panel Network & Internet Network and Sharing Center.
A “Home” network is most open A “Public” network is most closed
Click the “Change Advanced Sharing Settings” link at the left.

Network and Sharing Center
Turn on Network Discovery Turn on File and Printer Sharing Turn on “Sharing so that anyone with network …” Turn on Media Streaming Use 128-Bit encryption Turn Off Password Protection Sharing (if on a Home
Network) Allow Windows to Manage Homegroup Connections
(if on a Home Network)

Sharing Individual Drives or Folders
In the Windows Explorer (“Computer”), choose the library, folder, or drive you want to share.
Right-click it and click “Share With” Choose the users whom you will share with.

Sharing Individual Drives or Folders
You can adjust permissions for each user (or group) “Read” allows them to view the files (but not make
changes to them) “Read/Write” allows them to change or delete any of
the files in the shared folder.

SETTING UP NETWORKING
![Page 14: CAO 191 WW - LTCC Online · Set File and Folder Sharing To “share” a file or folder means to make it accessible by users other than the user who created the file or folder. To](https://reader033.vdocuments.site/reader033/viewer/2022042117/5e95317cae70496a7568ef44/html5/thumbnails/14.jpg)
Networks
“Networking” is simply the process of connecting 2 or more computers together, to allow them to share information and resources.
The Internet (capital “I”…originally the “InterNetwork”) is the mother of all networks.
Smaller scale are WANs (Wide Area Networks) and…
LANs (Local Area Networks) Such as you’d have in your own home.

A Home Network
![Page 16: CAO 191 WW - LTCC Online · Set File and Folder Sharing To “share” a file or folder means to make it accessible by users other than the user who created the file or folder. To](https://reader033.vdocuments.site/reader033/viewer/2022042117/5e95317cae70496a7568ef44/html5/thumbnails/16.jpg)
Select a Network Architecture
Windows 7 is a Network Operating System as well as a personal computer Operating System (Early versions of Windows on Personal Computers
needed a server with its own Network Operating System in order to be networked.
So you don’t need a home server, if you have Windows 7 computers
![Page 17: CAO 191 WW - LTCC Online · Set File and Folder Sharing To “share” a file or folder means to make it accessible by users other than the user who created the file or folder. To](https://reader033.vdocuments.site/reader033/viewer/2022042117/5e95317cae70496a7568ef44/html5/thumbnails/17.jpg)
Select a Network Architecture
Peer-to-Peer LANS: All computers in the LAN are both servers and clients,
and share in both providing and using resources. Any computer in the network may store information and
provide resources (such as printer or music files) for use by the other computers in the network.
Putting together a Peer-to-Peer network can be fairly inexpensive…cables (or wireless access points) for under $100.
![Page 18: CAO 191 WW - LTCC Online · Set File and Folder Sharing To “share” a file or folder means to make it accessible by users other than the user who created the file or folder. To](https://reader033.vdocuments.site/reader033/viewer/2022042117/5e95317cae70496a7568ef44/html5/thumbnails/18.jpg)
Select a Network Architecture
Client-Server LANs Servers manage the network and store information to
be shared on the network. They also manage printers and other resources.
![Page 19: CAO 191 WW - LTCC Online · Set File and Folder Sharing To “share” a file or folder means to make it accessible by users other than the user who created the file or folder. To](https://reader033.vdocuments.site/reader033/viewer/2022042117/5e95317cae70496a7568ef44/html5/thumbnails/19.jpg)
Select a Network Standard
Windows 7 supports the two predominant networking standards: wired Ethernet and wireless.
Wired Ethernet (most commonly now) is called 10/100/1000BaseT. This network will operate at regular Ethernet speed of
10 Mbps, Fast Ethernet speed of 100 Mbps, or Gigabit Ethernet speed of 1000 Mbps.
![Page 20: CAO 191 WW - LTCC Online · Set File and Folder Sharing To “share” a file or folder means to make it accessible by users other than the user who created the file or folder. To](https://reader033.vdocuments.site/reader033/viewer/2022042117/5e95317cae70496a7568ef44/html5/thumbnails/20.jpg)
Wired Networks
Wired networks need 3 components: Network Interface Card (NIC) Hub, switch, or router Cables (generally Unshielded Twisted Pair – UTP) Current standard is Category 6, prior are Cat 5 & Cat 5e
![Page 21: CAO 191 WW - LTCC Online · Set File and Folder Sharing To “share” a file or folder means to make it accessible by users other than the user who created the file or folder. To](https://reader033.vdocuments.site/reader033/viewer/2022042117/5e95317cae70496a7568ef44/html5/thumbnails/21.jpg)
Selecting Wired Ethernet Hardware
Hub: the oldest and simplest of switching devices…all computers are on the equivalent of a telephone party line…everybody can hear everybody else…all signals go everywhere.
Switch: (virtually made hubs obsolete) “intelligent” devices that funnel network traffic from one computer to another…like a private telephone line.
Router: joins 2 different networks (like the connecting Internet to a home LAN). Routers and switches are often combined in the same
device. (www.staples.com)

NICs
Most (if not all) new notebook/laptop computers come with a built-in Network Interface Card.
Desktop computers may or may not. You can buy NICs to go inside your desktop (generally
PCI these days), or Get an external NIC that connects through a USB port
(which you could also do for older laptops that don’t have a NIC built in).
![Page 23: CAO 191 WW - LTCC Online · Set File and Folder Sharing To “share” a file or folder means to make it accessible by users other than the user who created the file or folder. To](https://reader033.vdocuments.site/reader033/viewer/2022042117/5e95317cae70496a7568ef44/html5/thumbnails/23.jpg)
Using Wireless LANs
You can choose to replace your cables with radio signals by using a wireless LAN.
There are several standards in use now: 802.11b (the oldest) data transfer rates up to 11
Mbps. 802.11g (next newest) generally operates at 22 – 54
Mbps. 802.11n (newest) generally operates between 70 and
140 Mbps (though it can go up to 300 Mbps under perfect conditions).
All three standards are range-sensitive.

Using Wireless LANs
A Wireless LAN (WLAN) has two components: An Access Point – connects to the network by being
plugged into a hub, switch, or router (or being built into one of them).
An Adapter – plugs into (or built into) your computer.
Both are radio receivers/transmitters. Advantages:
No cables to run Easy to add new devices and computers.

Set Up Network Interface Cards
To see the NICs in your computer, Start Control Panel Network & Internet Network & Sharing Center
![Page 26: CAO 191 WW - LTCC Online · Set File and Folder Sharing To “share” a file or folder means to make it accessible by users other than the user who created the file or folder. To](https://reader033.vdocuments.site/reader033/viewer/2022042117/5e95317cae70496a7568ef44/html5/thumbnails/26.jpg)
Set Up Network Interface Cards
Click “Change Adapter Settings” to see which adapters in your computer are working.
You can see more device hardware information in the Device Manager Start Control Panel Hardware… then click the
link under “Devices and Printers” for “Device Manager”
![Page 27: CAO 191 WW - LTCC Online · Set File and Folder Sharing To “share” a file or folder means to make it accessible by users other than the user who created the file or folder. To](https://reader033.vdocuments.site/reader033/viewer/2022042117/5e95317cae70496a7568ef44/html5/thumbnails/27.jpg)
Selecting Wireless Hardware
Your wireless access point and wireless adapters need to talk using the same standard, so if buying new, consider that.
If you have a computer with wireless adapter already built in, check its standard. Use Device Manager, and look at its Properties, then its
“Details” tab.
