With the assumption that the term wifi means a wireless network between 2 or more computers, one only requires 3 basic components (besides the computers themselves): 2 (or more) wireless adapters and a wireless router or hub.
The adapters (assuming wireless functionality isn't built into the computers themselves) can be PCI cards, USB devices, or any one of the many possible devices currently on the market. You will need 1 wireless adapter per computer. These can be purchased at most retail electronic outlets.
The wireless router itself is usually a standalone device, purchasable at most retail electronic locations, that will provide a hub for the network as well as a gateway to other networks (such as the internet).
Exceptions:
Many WiFi devices are capable of connecting directly to each other (2 computer connecting directly via their adapters, without a router). A common example of this is handheld game consoles.
Hotspots are WiFi enabled locations in areas like coffeeshops, restaurants, etc. This means that someone with a Wifi enabled computer or device can connect to the Internet or other public network via a local wireless router. (1 computer with WiFi adapter and 1 public WiFi router)

How to do a hard reset on a Belkin G router?
If you are locked out of the router you will need to reset it. There will be a small button (usually at the back) with reset written beside it. You will probably need a paper clip or something to push it.
<><><>
Next to the power supply connection is a pinhole Reset button. Disconnect all cords from your router except the power cord. Press Reset button with a pin for 10 seconds. Wait 10 more seconds then unplug router. If it is then reset to the original factory settings you will have to reinstall it using software that came with router. You may have to reinstall your network card software as well.
<><><>
Some, but not all, routers have a reset button. Different routers require different steps to perform resetting. On many of them, to restore your own "personal setup" that was created when you first installed the router - not the original factory settings - you just have to disconnect the power supply and reconnect it after a minute or two. You will need to locate and read the manual if you cannot get to Belkin's support site online.
What are the advantages of sharing a printer?
A High Quality and Costly Printer can be Shared...!!
Space for keeping No. of Printers can be saved
How do you make your printer a wireless printer?
Its all about finding the printer on the network. Is it attached to a computer on the network? Or is it a network printer? Go to the machine you want to print from / control panel / printers / search for network printer.... and then just locate and add.
Make sure you have enabled printer and sharing on your machines. And watch out for firewalls.
First step to design a network is to prepare a layout . Then Protocols which are to be applied are decided. A network can be designed on Packet tracer (software) .
How do you connect to a secured wireless network?
To establish a connection with a secure Wi-Fi network, follow these steps:
- Open your device's wireless settings.
- Scan for available Wi-Fi networks.
- Select the desired secured network.
- Input the required security key or passphrase.
- Confirm the details and wait for a connection to be established.
Once connected, you'll have access to the secure wireless network.
Where can one buy a USB Ethernet adapter?
It has been found that USB Ethernet adapters are widely available. One can purchase these adapters at stores such as Best Buy, Walmart and Tiger Direct. These are also widely available online from sites such as Amazon and eBay.
Conclusion of computer network and communication?
The Native Computer Communications Network Project was a good example of how a focus on creating a network of computers does not necessarily ensure the interpersonal networking of the potential users of that technology. If the people were not communicating with each other before, developing another method of communication doesn't mean they'll start.
How do you use a wireless router?
This is a very hard question to answer because I do not know what router you are on about. Usually, most routers now will have a CD/DVD to help you set up your router.
Basically, what you really need to know when setting up your router is your internet login info, for example; name@dialbb.com. And of course the password. You can get this by phoning your internet provider.
Where can one buy a cable modem wireless router?
Their are many retailers where you can purchase a wireless DSL modem but I recommend going on Amazon and browsing through your options. I would recommend a netgear modem.
What is the scope in computer hardware networking?
It varies from computer to computer.. It's sometimes infrared and sometimes iron sight.
Can you connect to routers to a cable modem?
Not directly. To create a local wireless ethernet network connected to a cable modem a Wireless Ethernet Router Box (WERB) would be required. It connects to the Cable Modem (CM) using an ethernet cable.
If all you want is to have a local wireless ethernet network, the WERB would do that for you and you won't need to use the 2-Wire DSL wireless modem router.
The 2-Wire DSL wireless modem router really does the same as CM + WERB but for connection of local computers and peripherals to a 2-Wire DSL ISP instead of to a cable ISP.
Normally a cable modem connects to an ISP's cable network on one side and, on the other side, to either a single computer or to an ethernet router which could be either of the hard-wired "local cable" type or a "local wireless" type. The ethernet router then connects to several local computers or peripheral devices such as printers, scanners, etc.
A DSL wireless modem router connects to an ISP's 2-wire copper telephone line on one side and, on the other side, via a local wireless ethernet to several local computers or other peripherals such as printers, scanners, etc., each of which must have a local wireless ethernet connectivity device. It is not clear from the question that you want to enable local computer users to connect reliably to either the ISP handled by the DSL wireless modem router or to the ISP handled by the cable modem. If that is what you want, then, if you are not already familiar with setting-up ethernet devices -- which may be the case as you asked this question here -- either get an ethernet router expert to help you or read the instructions that come with all modems and routers to find out what to do.
Can you run 2 wireless networks in one house?
Yes. However, their role in interconnecting your home network needs to be defined in order to correctly deploy them. Each wireless router has a unique MAC address (Media Access Control) that differentiates it from every other network interface device, so at the network level accidental conflicts are highly unlikely. Additionally, you need to select an SSID (Service Set Identifier) for your wireless router, which further differentiates it from other routers in the house, in the apartment next door, etc.
While you can have many wireless routers in any given area (inside your apartment building, or even in your own house), an important point is where each router will be connected to the "upstream" network connection, presumably eventually reaching the Internet. These points should be understood and defined prior to deploying multiple routers in any given location.
Yes, you can add printers to your Netbook. As long as you Netbook have USB ( nearly all the Netbooks have it. One can connect their Netbooks to the any printers that enables USB drives.
As I am a student, and I am using Intel Atom embedded Netbook and requires to take many printouts as the requirement of my subjects. More importantly, Intel Atom Netbooks are lightweight and easy to take anywhere. Intel Netbooks is much lesser price as compare with Laptop and with a great battery life (approx. to 10- 12 Hrs.).
What is a benefit of not broadcasting SSID for your wireless network?
Strangers won't see your wireless network, making it more difficult to hack. The downside is that when you want to add new devices, they won't be able to see it automtically either. You will need to manually enter the network ID.
Can tin foil block Wi-Fi signals like the radiation from wireless acces points?
Metals in general block electromagnetic radiation (which is what a Wi-Fi signal is). Aluminium foil is a metal, so ...Exactly how this happens is a bit more complicated than can reasonably be explained here, but it basically has to do with the fact that metals are conductive. They "absorb" the electromagnetic signal and turn it into electrical currents within the metal.
You don't even need to use solid metal, you can accomplish the same thing with a wire cage as long as the spacing between the wires is small compared to the wavelength of the radiation (for Wi-Fi at 2.4 GHz, this is about 5 inches). This is called a "Faraday cage." The basic concept is used in a lot of electronics devices to shield out interference (or keep the device from interfering with anything else), though it's more common for them to use a piece of thin sheet metal with maybe a few holes in it for ventilation than to go to the trouble of constructing a wire mesh.
How do you make my PC wireless?
If you mean a wireless network connection - you should buy a WiFi adapter (USB or PCI or PCI-e), install it in your computer and then set-up a new network connection.
If you mean wireless as no-cable-power - there is a problem. Desktop computer uses much more power than laptop and no battery can power it for a time longer than few minutes.

What are reasons for using a network?
Linear equations in two variables
A common form of a linear equation in the two variables xand y is
where m and b designate constants. The origin of the name "linear" comes from the fact that the set of solutions of such an equation forms a straight line in the plane. In this particular equation, the constant m determines the slope or gradient of that line, and the constant term b determines the point at which the line crosses the y-axis, otherwise known as the y-intercept.
Since terms of linear equations cannot contain products of distinct or equal variables, nor any power (other than 1) or other function of a variable, equations involving terms such as xy, x2, y1/3, and sin(x) are nonlinear.
Forms for 2D linear equationsLinear equations can be rewritten using the laws of elementary algebra into several different forms. These equations are often referred to as the "equations of the straight line." In what follows, x, y, t, and θ are variables; other letters represent constants (fixed numbers). General (or standard) formIn the general (or standard[1]) form the linear equation is written as:where A and B are not both equal to zero. The equation is usually written so that A ≥ 0, by convention. The graph of the equation is a straight line, and every straight line can be represented by an equation in the above form. If A is nonzero, then the x-intercept, that is, the x-coordinate of the point where the graph crosses the x-axis (where, y is zero), is C/A. If B is nonzero, then the y-intercept, that is the y-coordinate of the point where the graph crosses the y-axis (where x is zero), is C/B, and the slope of the line is −A/B. The general form is sometimes written as: where a and b are not both equal to zero. The two versions can be converted from one to the other by moving the constant term to the other side of the equal sign. Slope--intercept formwhere m is the slope of the line and b is the y-intercept, which is the y-coordinate of the location where line crosses the y axis. This can be seen by letting x = 0, which immediately gives y = b. It may be helpful to think about this in terms of y = b + mx; where the line passes through the point (0, b) and extends to the left and right at a slope of m. Vertical lines, having undefined slope, cannot be represented by this form. Point--slope formwhere m is the slope of the line and (x1,y1) is any point on the line.The point-slope form expresses the fact that the difference in the y coordinate between two points on a line (that is, y − y1) is proportional to the difference in the x coordinate (that is, x − x1). The proportionality constant is m (the slope of the line). Two-point formwhere (x1, y1) and (x2, y2) are two points on the line with x2 ≠ x1. This is equivalent to the point-slope form above, where the slope is explicitly given as (y2 − y1)/(x2 − x1).Multiplying both sides of this equation by (x2 − x1) yields a form of the line generally referred to as the symmetric form:
Intercept formwhere a and b must be nonzero. The graph of the equation has x-intercept a and y-intercept b. The intercept form is in standard form with A = 1/a and B = 1/b. Matrix formUsing the order of the standard form
one can rewrite the equation in matrix form:
Further, this representation extends to systems of linear equations.
becomes
Since this extends easily to higher dimensions, it is a common representation in linear algebra, and in computer programming. There are named methods for solving simultaneous linear equations like Gauss-Jordan which can be expressed as matrix elementary row operations.
Parametric formand Two simultaneous equations in terms of a variable parameter t, with slope m = V / T, x-intercept (VU−WT) / V and y-intercept (WT−VU) / T.This can also be related to the two-point form, where T = p−h, U = h, V = q−k, and W = k: and In this case t varies from 0 at point (h,k) to 1 at point (p,q), with values of t between 0 and 1 providing interpolation and other values of t providing extrapolation. Polar formwhere m is the slope of the line and b is the y-intercept. When θ = 0 the graph will be undefined. The equation can be rewritten to eliminate discontinuities: Normal formThe normal segment for a given line is defined to be the line segment drawn from the origin perpendicular to the line. This segment joins the origin with the closest point on the line to the origin. The normal form of the equation of a straight line is given by: where θ is the angle of inclination of the normal segment, and p is the length of the normal segment. The normal form can be derived from the general form by dividing all of the coefficients byThis form is also called the Hesse standard form,[citation needed] after the German mathematician Ludwig Otto Hesse.shawal is the bestIt's known to be hacked but requires a lot of resources. It can be hacked but not easily.
It looks like a small device with glowing light emitting diodes, (when turned on) and slots placed behind to have cables from the computer and from the phone line connected into it. It has an input for the power supply, also. Its shape is usually rectangular.
