What is a network card?


Wikipedia says:
A network interface controller (also known as a network interface card, network adapter, LAN adapter and by similar terms) is a computer hardware component that connects a computer to a computer network.[1]

Early network interface controllers were commonly implemented on expansion cards that plugged into a computer bus; the low cost and ubiquity of the Ethernet standard means that most newer computers have a network interface built into the motherboard.

Connecting Two Computers Directly With Cable for a home network


The simplest and easy way to start a home network 


The simplest kind and easy to maintain of home network contains exactly two computers. You can use this kind of network to share files, a printer or another peripheral device, and even an Internet connection. To connect two computers for sharing these and other network resources, consider the options described below.
Connecting Two Computers Directly With Cable

The traditional method to network two computers involves making a dedicated link by plugging one cable into the two systems. Several alternatives exist for networking two computers in this manner: Ethernet crossover cable
Null modem serial cable or parallel peripheral cable
Special-purpose USB cables
Ethernet crossover cable
Null modem serial cable or parallel peripheral cable
Special-purpose USB cables
Ethernet - Of the above choices, the Ethernet method is preferred as it supports a reliable, high-speed connection with minimal configuration required. Additionally, Ethernet technology offers the most general-purpose solution, allowing networks with more than two computers to be built fairly easily later. If one of your computers possesses an Ethernet adapter but the other has USB, an Ethernet crossover cable can still be used by first plugging a USB-to-Ethernet converter unit into the computer's USB port.

Ethernet crossover cables

Serial and parallel - This type of cabling, called Direct Cable Connection (DCC) when using Microsoft Windows, offers lower performance but offers the same basic functionality as Ethernet cables. You may prefer this option if you have such cables readily available and network speed is not a concern. Serial and parallel cables are never used to network more than two computers.

USB - Ordinary USB cables must not be used to connect two computers directly to each other. Attempting to do so can electrically damage the computers! However, special USB cables designed for direct connection exist that can be used safely. You may prefer this option over others if your computers lack functional Ethernet network adapters.

To make dedicated connections with Ethernet, USB, serial or parallel cables requires
each computer have a functioning network interface with an external jack for the cable, and
the network settings on each computer appropriately configured
One phone line or power cord cannot be used to directly connect two computers to each other for networking.

Connecting Two Computers with Cable through Central Infrastructure
Rather than cable two computers directly, the computers may instead be joined indirectly through a central network fixture. This method requires two network cables, one connecting each computer to the fixture. Several types of fixtures exist for home networking: Ethernet hubs, switches, and routers 
USB hubs
Phoneline and powerline wall outlets
Ethernet hubs, switches, and routers
USB hubs
Phoneline and powerline wall outlets

Implementing this method often entails additional up-front cost to purchase more cables and network infrastructure. However, it's a general-purpose solution accommodating any reasonable number of devices (e.g, ten or more). You will likely prefer this approach if you intend to expand your network in the future.

Most cabled networks utilize Ethernet technology. Alternatively, USB hubs can be employed, while powerline and phoneline home networks each offer their own unique form of central infrastructure. The traditional Ethernet solutions are generally very reliable and offer high performance.
Connecting Two Computers Wirelessly
In recent years, wireless solutions have enjoyed increasing popularity for home networking. As with cabled solutions, several different wireless technologies exist to support basic two computer networks: Wi-Fi
Bluetooth
infrared
Wi-Fi
Bluetooth
infrared
Wi-Fi connections can reach a greater distance than the wireless alternatives listed above. Many newer computers, especially laptops, now contain built-in Wi-Fi capability, making it the preferred choice in most situations. Wi-Fi can be used either with or without a network fixture. With two computers, Wi-Fi networking minus a fixture (also called ad-hoc mode) is especially simple to set up. How To - Set Up an Ad Hoc WiFi Network

How To - Set Up an Ad Hoc WiFi Network

Bluetooth technology supports reasonably high-speed wireless connections between two computers without the need for a network fixture. Bluetooth is more commonly used when networking a computer with a consumer handheld device like a cell phone. Most desktop and older computers do not possess Bluetooth capability. Bluetooth works best if both devices are in the same room in close proximity to each other. Consider Bluetooth if you have interest in networking with hand held devices and your computers lack Wi-Fi capability. 

Infrared networking existed on laptops years before either Wi-Fi or Bluetooth technologies became popular. Infrared connections only work between two computers, do not require a fixture, and are reasonably fast. Being very simple to set up and use, consider infrared if your computers support it and you lack the desire to invest effort in Wi-Fi or Bluetooth.

If you find mention of an alternative wireless technology called Home RF, you can safely ignore it. Home RF technology became obsolete several years ago and is not a practical option for home networking.

Try it is the best home network option.

I want to network two pc with windows xp using crossover cable,, how do i do it step by step pls.


Connect two computers using a crossover cable
If you need to connect two computers but you don't have access to a network and can't set up an ad hoc network, you can use an Ethernet crossover cable to create a direct cable connection.
Generally speaking, a crossover cable is constructed by reversing ("crossing over") the order of the wires inside so that it can connect two computers directly. A crossover cable looks almost exactly like a regular Ethernet cable (a "straight-through" cable), so make sure you have a crossover cable before following these steps.
Before buying a crossover cable, check your network adapter. Some newer network adapters automatically "cross over" when they detect that they are connected directly to another network adapter using a regular Ethernet cable.
To connect two computers with a crossover cable
This works best if both computers are running this version of Windows.
Plug each end of the crossover cable into a network port on the back of each computer.
On one of the computers that is running this version of Windows, do the following:
Open Network and Sharing Center by clicking the Start button , clicking Control Panel, clicking Network and Internet, and then clicking Network and Sharing Center.
In the network map at the top of Network and Sharing Center, double-click the Unidentified network? icon. (If you have more than one network, this icon will be labeled Multiple networks.)
If network discovery and file sharing are turned off, in Network, click the Information bar containing the following message: "Network discovery and file sharing are turned off. Network computers and devices are not visible. Click to change...," and then click Turn on network discovery and file sharing. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
In the Network discovery and file sharing dialog box, select one of the following options:
No, make the network that I am connected to a private network
Yes, turn on network discovery and file sharing for all public networks
The first option is usually the best choice because it only affects the network that you are connected to.
Notes
Networks created with crossover cables are automatically set up as "Public place" networks, which means that network discovery, file sharing, and printer sharing are off by default.
For Gigabit Ethernet or token ring networks, you will need a slightly different kind of crossover cable. For more information, contact a cable manufacturer.
Icons for both computers should now be visible in the Network window. Double-click each computer icon to share printers and other resources.
Note
If one of the computers is running Windows XP, it can take some time for that computer to appear in the Network window. You might need to move both computers to the same workgroup. You can do that by changing the workgroup on either computer. To change a workgroup, see Join or create a workgroup. You might also need to turn on file and printer sharing on the computer running Windows XP.
Hope this help!

How to install an wirless adapter to mi desktop


Install a wireless network adapterIn areas that are served by a wireless network, you can connect to a computer network without using a cable, and surf the Internet or connect with other computers. To connect to a wireless network, your computer needs a wireless network adapter.
Many new computers-especially laptops-come with wireless adapters. Before using your computer, check to see if it already has a wireless network adapter.
If your computer doesn't have a wireless network adapter, you can install one.
Install a wireless USB network adapter. Most people prefer this type of adapter for any type of computer, because it's easy to install.
Install a wireless CardBus or CF network adapter. For portable computers, this type of adapter (also called a PCMCIA or PC Card) is easier to travel with than a USB adapter, because it is often smaller and fits securely in the PC Card slot on the side of the computer.
Install a wireless internal network adapter. If you have a desktop computer, you may prefer an internal adapter so that you can use the USB port to connect another accessory.
The type of adapter you install depends on your computer and your level of expertise.
How to determine if you already have a wireless network adapterMany portable computers manufactured after 2000 have wireless networking built in. However, because the antenna is hidden inside the computer, it's not easy to see.
To see which network adapters are currently installed in your computer
1.
Click Start, and then click Control Panel.
69010-click-control-panel.gif 2.
Click Network and Internet Connections.
69010-click-network-and-internet-connections.gif 3.
Under or pick a Control Panel icon, click Network Connections.
69010-click-network-connections.gif 4.
Microsoft Windows XP displays your network adapters. Wireless network adapters are labeled Wireless Network Connection. If an adapter displays a red X, it is disconnected. If the Network Connections window is blank, your computer doesn't yet have a wired or wireless network adapter.

Sir can i connect two pcs one desktop and other laptop for sharing files bw the two and playing games bw them


There are a couple of ways you can network two computers together.
Each computer must have a network card installed together with the LAN card drivers. The two computers needs to be connected to a network hub and these computers need to be set up on the same workgroup name.
Using a network hub will allow more the two computers to be connected to a network and the number of computers that can be installed on this network depends upon the number of available ports on the network hub.
You can use a Crossover LAN cable to connect the two computers together and you won't need a network hub.

Hello wots an router somthing to do withs to internet and how do reinstall it


To understand what a router does, you need to know a little bit about how the Internet works. The Internet, the huge world-wide computer network that we surf the World Wide Web on, uses the TCP/IP networking protocol. Data sent over a TCP/IP network is broken down into chunks called "packets", and in order for these packets to get where they need to go on the Internet, something is needed to route them to their destinations (hence the name router). The many networks that make up the Internet are connected to each other by routers, and the routers determine what packets go where. Routers are level 3 devices on the OSI model, which means that they function at the network layer. The OSI model has 7 levels, and each one represents a function when it comes to data communication between two or more computers on a computer network. To understand what I'm talking about in the next paragraph, you need to know about the OSI model and what layer the router represents.

When the average computer user thinks of a router, they probably think of the kind that you can purchase at your local computer store, as opposed to the big ones that route packets on the Internet. That smaller kind of router allows you to share an Internet connection with multiple computers without having to use a computer that acts as a "gateway". If you have a computer network at home and the center of it is a hub or a switch, you need to use a computer that acts as a gateway ("host" computer), as hubs and switches cannot do what a router does (hubs and switches are two other devices that you can purchase at your local computer store to create a network between two or more computers). A router can "intelligently" route TCP/IP packets to IP addresses (unique identifiers on a TCP/IP network) at layer 3, while a hub is just a dumb layer 1 device that sends out packets to all of the computers attached to it, regardless of who sent them out and who they're intended for. A switch is a layer 2 device that routes Ethernet frames by MAC address; Ethernet is a networking standard that home networks are based on, a frame is the Ethernet equivalent of a TCP/IP packet (chunk of data), and a MAC address is a computer's unique identifier at layer 2 (datalink) on an Ethernet network. Although a switch is "smarter" than a hub, it still can't do what a router does. The functions that a router performs are necessary for communication between the computers on your network and computers on other networks on the Internet at the network layer (TCP/IP). Probably the most important thing that a router does is perform NAT, which stands for Network Address Translation. NAT is a technology that allows computers on a network behind an Internet connection to communicate with computers outside the network; to the rest of the Internet the network is a single IP address (the one your ISP gave you), and NAT allows for incoming and outgoing connections between the computers on the network who have their own "internal" IP addresses and the computers outside the network who see only the ISP-assigned IP address. A "gateway" computer using Internet connection sharing software like the kind that Windows comes with performs the same functions as a hardware router, but there are some disadvantages that come with using that setup, like how all of the computers on the network lose Internet access if the gateway computer is offline. If you want to share an Internet connection between two or more computers in your home, a hardware router is the best thing to get for it.
