What are networks of computers that are connected over greater distances?
Network over geographical distances are known as WANs (Wide Area Networks)
How data communication and digital communication differ?
In digital communication we talk about signal while in data communication we talk about data and the could be in the form of packets or frames.
What types of things are shared in local area network?
Anything on a drive including the drive can be shared, devices such as printers or network adapters, & camera's etc. Exceptions would be system files and program files which are attached to the registry of a said computer. You may be able to see the files in a explorer window but unless setup on the executing system there would be flags stopping any attempts.
Sounds easy enough right? It does get tricky, starting with what is called permissions, rights and ownership of any data & hardware to be shared. Also there are the hardware and driver configurations, network types and protocols, (which are computing communication language's ) the domain and sub-domain configurations, gateway's, firewalls, security, and ISPs (a internet service provider.) Just when you think the later is all set correctly configured and working, there may be more issues arise depending on the environment.
I am only guessing you would like just to share a folder or two and maybe a printer? Without the brain damage correct? If you are using a computer from at least this century this is really not to difficult for one who is familiar with basic networking architecture. Use the setup Wizards, setting up a connection type of broadband "always on". Then finish up the wizard and in most cases if the ground work is done correctly, you're up an sharing pretty quick!
A couple things I will share with you about this topic may save you some brain damage.
First off if this is a situation where one would like to share a desktop at home and work, there are options using a cloud drive for syncing folders between computers. (two or even more) I use Zumodrive which is real nice (one or two free gigs!), for the home and work or even a multiple location use for syncing and sharing files. Google offers many options now also, great if you use G mail and everything Google. I just checked and Zumodrive be gone? There are other options "O" plenty, just look for desktop sync or cloud drive etc.
Setting up a basic network, some things to look out for:
Computer Names
Sharing enabled
User rights
Firewall settings for IP address and port access
Network errors of any kind
Security between the WideAreaNetwork "WAN and LocalAreaNetwork "LAN"
adapter connections set for home or work office - Not Public!
Learn to use the ping command
After all is set just right the network will work like a champ. There are plenty of resources online and in windows help for learning, questions, and any issues. Just search for setting up a LAN or a small office network. When you're up and running all that is left is to simply right click a file, folder, or drive and share > advance sharing, then naming the share and giving it permissions.
Good luck, I hope this is helpful?

What are the main differences between the public and private network settings?
Public network is where the networked computers are not all trusted. Private network is where all computers are trusted. EG. Public network: cyber cafe. EG Private network: Your work or home network.
Less expensive - Several miles of optical cable can be made cheaper than equivalent lengths of copper wire.
Higher carrying capacity - Because optical fibres are thinner than copper wires, more fibres can be bundled into a given-diameter cable than copper wires. This allows more phone lines to go over the same cable or more channels to come through the cable into your cable TV box.
Less signal degradation - The loss of signal in optical fibre is less than in copper wire.
Light signals - Unlike electrical signals in copper wires, light signals from one fibre do not interfere with those of other fibres in the same cable. This means clearer phone conversations or TV reception.
Digital signals - Optical fibres are ideally suited for carrying digital information, which is especially useful in computer networks.
Non-flammable - Because no electricity is passed through optical fibres, there is no fire hazard.
Lightweight and thin - An optical cable weighs less than a comparable copper wire cable. Optical fibres can be drawn to smaller diameters than copper wire. Fibre-optic cables take up less space in the ground.
What is a major advantage of UTP?
It is inexpensive. It limits the number of hosts on a network. It is an inexpensive way to interconnect remote locations. UTP stands for Unshielded Twisted Pair. Unshielded means just as its name suggests. It offers absolutely NO protection against EMI, or electromagnetic interference.
What are the advantages of having a redundant network?
If you look at redundant networks in nature, like the network of the veins within a leaf you may realize that redundancy creates resilience.
Often leaves are subjected to parasites or physical damage. If a vital vein is struck in a network without redundancy it would mean all tissues or nodes which it previously fed into would be effectively annihilated from the network (death). A redundant network overcomes this problem by spreading out the risk.
From a Computational standpoint this would be the same problem. Often critical layers of a network if left without connectivity would create critical failures for parts of the network which may be dependent on its activity. Such is the nature of hierarchy.
a hub is the area at the end of your axle where your tire mounts,the middle of your tire has a hole in it where the hub sticks out and this holds the bearings that your tire rotates on most are packed with grease to lube the bearings. when you have a hub cap on your tire ....well you get the idea
What are the three primary functions of the presentation layer?
Coding and conversion of Application layer data to ensure that data from the source device can be interpreted by the appropriate application on the destination device.
Compression of the data in a manner that can be decompressed by the destination device.
Encryption of the data for transmission and the decryption of data upon receipt by the destination.
Telnet is a Network layer protocol. It is used to create connection remotely.
What should be considered when choosing the length of an anchor cable?
The depth of the water should be considered when choosing the length of an anchor cable. The anchor cable needs to be 4 to 7 times longer then the depth of the water.
What is the maximum number of bits that can be borrowed with class b?
The maximum number of host bits that can be borrowed from a class A address is 22 (technically you could borrow 23 but the resulting network would be useless).
A class A address uses 8 bits for its network address and 24 bits for its host addresses. Class A uses a subnet mask of 255.0.0.0
You can only borrow 22 bits (instead of 24) because a valid network requires 4 addresses: A network address, two host addresses and a broadcast address. These networks would result in 30 bits used for the network address and 2 bits used for the host addresses. These networks use a subnet mask of 255.255.255.252
What mechanism is used by wireless technologies to avoid collisions in the wireless domain?
CSMA/CA (Carrier Sense Multiple Access/Collision Avoidance)
Ftp is a file transfer protocol use with TCP/IP Protocol to transfer files directly to a server through the internet.
How many user roles may each GCSS-Army user be assigned in an?
Multiple user roles, depending upon the user's level of responsibility
How do you transfer music from your MacBook Pro to your cell phone?
You can't. But you can share from MacBook Pro to iPhone4.
I say Star Topology. Watch this video: http://www.youtube.com/watch?v=ihb_qa6qTbE It explains different topologies. Good luck
What is Mac address of the wireless adapter?
MAC addresses are a kind of serial number. They are supposed to be unique worldwide; that is, two different network equipments, even of the same kind, will have different MAC addresses. They are used for communication, to identify the individual pieces of equipment.

The simplest form of a network is a client server network?
False - a peer-to-peer network is simpler.
Traffic using port 25 from the 10.25.132.0/24 is permitted to all destinations.
What program can capture packets on a network?
A packet capture (or sniffer) program sees packets coming into and out of the NIC (network interface card). It saves it for later analysis and use. These capture programs can be used to analyze traffic, look for problems, or be used for looking at data coming across the network.
What is the defference between the net the web and cyberspace?
The Internet is the global communication network, both hardware and software infrastructure that links smaller computer networks throughout the world. Most people use the term as a loose synonym for WWW (World Wide Web), a system of interlinked hypertext documents ("website pages") accessed through the Internet. Cyberspace, on the other hand, is a vaguely defined term - invented by William Gibson - that refers the non-geographical, virtual, even metaphoric space in which all computer objects "exist". The term can include the entire content on the Internet, as well as the objects created by virtual reality simulations and computer games. What you should know is that the exact definition of the term is non-existent. Some people use it as a metaphor for the Internet; some people use it as an all-encompassing term for general networking and anything associated with computers; there are some people then who use the term in a philosophical sense, as an alternative reality of some sort. Practically speaking, it probably makes more sense to leave "cyberspace" to science fiction writers and use less pompous "Internet" and "World Wide Web" for descriptions of one's everyday online experiences.
"Cyberspace. A consensual hallucination experienced daily by billions of legitimate operators, in every nation, by children being taught mathematical concepts... A graphic representation of data abstracted from banks of every computer in the human system. Unthinkable complexity. Lines of light ranged in the nonspace of the mind, clusters and constellations of data." -William Gibson, Neuromancer.
"All I knew about the word 'cyberspace' when I coined it, was that it seemed like an effective buzzword. It seemed evocative and essentially meaningless. It was suggestive of something, but had no real semantic meaning, even for me, as I saw it emerge on the page." -William Gibson, No Maps for These Territories.
