Computer Networking
Computer networks are collections of computers which are connected together in order to communicate and transfer information. Questions about computer networks, networking protocols, and how to set them up belong here.

Is 1 GbE Ethernet really Ethernet Explain?
Yes; Ethernet is really not a single technology, but a family of technologies. Details vary, for example between fiber optic and copper cable; but it is still considered "Ethernet".

How do you turn on wireless interent on an e system laptop?
Generally, it is by holding down the blue "Fn" button at the bottom left of keyboard then pressing "F10" - it should have a little green wireless light glows up on the bottom of the computer by the charging icon etc
How can a composite signal be decomposed into its individual frequencies?
Fourier analysis
Frequency-domain graphs
Trick someone into turning off computer?
In terms of keyboard shortcuts (Assuming you're wanting to say, "Press [this] to do something cool!" User presses, and computer shuts down), there is no such default shortcut to completely turn off the computer; put it in standby or hibernation mode; or restart (Except for the power button, which on some computers, may achieve the desired effect. Power buttons can be, and sometimes are, designed differently for different company's computers.)
What are good reasons for installing a LAN?
There are really only two reasons for using a LAN:
- To have others share resources
- To add security
Can 2 binary numbers have the same decimal value?
Two numbers that have the same decimal value will have the same binary value. Binary is simply a representation of a number in base 2, while decimal is base 10.
For example, consider the number 104 in base 10. In this system, we can break down each digit due to the distributive law.
104 = 1 * (10^2) + 0 * (10^1) + 4 * (10^0) = 100 + 0 + 4 = 104
To convert to base 2, we can find the largest power of two that is less than our base 10 number and work backwards from there, in this case we start at 2^6 or 64
2^6 = 64
104 - 64 = 40
2^5 = 32
40 - 32 = 8
2^3 = 8
8 - 8 = 0
so therefore:
104 = 1 * (2^6) + 1 * (2^5) + 0 * (2^4) + 1 * (2^3) + 0 * (2^2) + 0 * (2^1) + 0 * (2^0)
meaning that 104 base 10 is equal to 1101000 base 2.

What Name some services provided by the application layers in the internet model?
file, printer, applications, and data base service
What is the difference between client operating system and server operating system?
A client operating system is generally a single user operating system where only 1 user can be actively using the computer at any one time. Video and audio are important to the 'users' to have a rich experience.
A server operating system is a multi-user operating system where it is optimized for multiple user access at the same time sharing all of the resources. Audio services may be limited and the video experience is not very important as many servers do not have dedicated monitors or keyboards (operate headless)
How can you use a broadband connection on a different floor of the house without an ethernet cable?
the easiest way is with a wireless router so that you can use a wireless laptop or wireless adpated PC anywhere in the house
What strategies produce the fewest results using the words punishment and capital?
Peer-reviewed documents published in 2003. Produces only 9 results.

How can bulletin boards be controlled so that illegal material is not distributed?
The problem is, the internet is by design, not really "managed" by one person or group of people. It's just there, anyone can connect provided that they follow the protocols, which are more concerned with data formatting than they are with data content. If a website causes damage to you, you MAY be able to sue for damages or possibly even prosecute for criminal activity, but that is only if you can identify the individual or corporation. "Control" and "internet" do not seem to be words that work well in a sentence... unfortunately.
Which computer and network service companies went national in 2007?
Masley And Associates was founded in 1987 by my father John Masley in Southern California. In 1994 I graduated from Network Engineer School with my CNE, CNA and MCSE and took over the business. We had one simple goal in mind: To offer seasoned, experienced, professional, certified network engineers and network administrators to local companies in Southern California and Southern Colorado at the same low cost as the less qualified "PC Geek" competition.
Business was well received when clients realized the amount of money and time they were saving using our experienced network engineers and network administrators over the PC technicians that they had been using with their previous IT support companies and the business grew.
Soon after customers were requesting Masley And Associates network engineers and network administrators in other states and in 2007 the company grew from MasleyAssociates.com which focussed on local companies in Southern California and Southern Colorado to MasleyAssociates.info Nationwide computer and network repair, sales, service, support and maintenance.
For more information on how we can provide your company with better IT support services than you have received in the past for the same cost contact Greg Masley CNE, CNA, MCSE at (719)649-7451 Greg@masleyassociates.com http://www.masleyassociates.com or http://www.masleyassociates.info
When signing up on on to a website what does characters mean?
The characters are like the letters of the alphabet, exclamation marks, dollars signs, etc, unless other wise specified. Everything I just wrote here are characters. "Use 6 to 8 Characters" would mean just type in a 6 or 8 letter word or random letters.
Alpha/Numeric would be letters and numbers like a password:.....answer22it.com......would be alpha/numeric.
Add up all the bits in a "word" - usually in 7 bits of an 8 but byte, and use the top bit in the byte to store the result. If there is an even number of bits set, the "parity bit" is 0, and if it is odd, the "parity bit" should be 1.
Electronic circuits can easily be made that generates this on say a COM port, that transmits one bit at a time and makes it possible to detect errors in the communication. It is also used in RAM memory - also to identify faulty memory chips. On disks they use more than 1 bit, and will here call it "ECC" - "Error Correction Circuitry". This is based on 3 bits that enables reconstructing the byte, not just detect an error.
Dense storage and fast transmission is always a trade-off with the correct stored data or data transmitted. Where the errors can be corrected without reducing capacity this is used.
What is the reserved block for default routing?
0.0.0.0: The wildcard used to say "any" network not already in the routing table
Can client operating systems be used without a network?
yes, because maisha brown said so. if you have a problem come shake, all jokes aside.
I would do some research into a capture device which has no delay time.

for any wireless network work you need the following two things working in conjunction with eachother:
1: a wireless signal (from your own wireless router, or one you "steal" from a neighbor)
2: a wireless receiver (built-in, usb adapter, etc)
so yes you can use the usb to get on the net, but only with a signal, probably from your own wireless router.
// one dimensional array 'num' of type int...
int num[100];
{Sorry, diagrams are not possible in wiki.answers.com, you have to use words}
This is 100 copies of an integer data type, arranged sequentially in memory. The first one is called num[0], the tenth one is called num[9], and the 100th one is called num[99].
// two dimensional array 'matrix' of type float...
float matrix[10][20];
This is 200 copies of a floating point data type, arranged sequentially in memory. The first one is called matrix[0][0], the tenth one is called matrix[9][0], the eleventh one is called matrix[0][1], and the 200th one is called matrix[9][19].
In both cases, you don't want to "think" about the arrangement of bits and bytes within each int or float. Doing so is non-portable, and can lead to problems down the road. The only safe thing you can consider is the arrangement in memory of the copies of the fundamental type int or float.
