Setting up your home network

How to change society and technology, an it/all for the home, to have more than one computer. When an existing computer for several years, parents will often use the today/to lower prices, buy a new computer and old to children.

Suddenly, there’s a need for a  home network so that all computers in the House to share a files, printers, and an Internet connection. Fortunately, setting up a basic home network is not a whole science. To start, you , you’ll need a router, which becomes the center point on your network. More office and online stores offer kits for home networking with a router, ethernet (network) and CAT-5 network cable.

If the team met in the past five years, you probably already have an ethernet adapter. Check the back of the system unit for a port that looks like a telephone connector, but slightly larger.

If you don ‘t have a  ethernet adapter, you can purchase one (about € 20) and install it yourself. You can also use a special ethernet adapter that connects to a USB port, if you can ‘t connect  the thought of opening your system drive to install an ethernet adapter.

Wired or wireless network?

You need to link each with  computer using a cable or go wireless. If you want to use wireless connections, you need  wireless router and the wireless network adapter for each computer. Most laptops have a wireless adapter built in, most desktop models do not. If you need a wireless adapter, you can buy one that installs inside the system unit or get a USB-style.

With a wireless network eliminates the need for unsightly cables in a string of all around the House, but it can also pose a security risk. Wireless networks often are configured by default to allow access to any computer that is trying to connect. Therefore, an evil hacker, driving with a laptop (or even your neighbor) may be able to connect to the Internet, or poke around the hard drive.

Fortunately, it is easy to set up security for wireless encryption. See my article Wireless Security for detailed instructions.

Network configuration

Whether network signals travel through a wire or air, network resources, still must be shared so that other computers can access them. If you are using Windows XP or MacOS X, everything you need to do is connect your computers and high-speed modems, and Internet connection sharing you simply work like magic. Otherwise, restart cable modem, router and computers (in that order), and see if it runs left. If you can — without access to the Internet from one or more computers on your network, refer to the manual included with the router.

To take advantage of the nice side of the router one is that they have built hardware firewalls. Firewalls protect networks from attacks that originate by hiding the computers but still allow Internet and e-mail. After you install a router, so you can turn off the Windows Firewall and any other software-based firewalls may need to be running.

Share files and printers

Share files and printers on a network Windows also very painless. To share a printer, go to the printers section of Control Panel, right-click the icon for the printer that needs to be shared, and then choose share the resulting menu. By specifying a name for the shared printer, the owner allows other computers on my network attempts to access the printer browsing using symbols network neighborhood (or my network places). Can only found on some computers or users through the use of options or security permissions on the shared screen.

The same concept applies to shared files and folders on a network. For example, if you want to share a collection of MP3 files on a home network, simply browse to the folder by using the my computer icon, right-click the folder name, and then click Sharing. After assigning a name to the share and set permissions, other computers on your network to access this resource via network neighborhood or my network places. CRM Software

The first thing to notice when discussing about securing a computer network is a network structure which will be implemented. Position the computer and other pieces of equipment is important, therefore, you must have a server and router, propagation environment and medium pieces of equipment that is placed in a place where administrators can access them and where users can access them, too. The main elements that you need to build a network depends on the company’s needs and preferences.

First of all, you have to select the required Internet connection in the network. The higher the traffic, the greater the bandwidth, but of course, the greater the cost, too. If You only need the Internet to check my e-mail, navigate through the browser or use other applications don ‘ t require  Internet connection-intensive, You can go for a simpler connection.

The main element of this puzzle is the server, and is therefore very important that make a good choice and buy a high quality product. Of course, all the pieces of the team are chosen finally according to the volume of data that mediate, reason why all options are on. Le shouldn ‘ t neglecting the less expensive pieces of equipment, such as passive elements, which would be the switches or cables. These pieces of equipment also play a very important role in the smooth functioning of your connection and network. Laminating Machine

Network your computer is not only on your computer, and digital devices to transfer data. These units different from the technologies used in different networks. But network equipment can be listed as a network interface card (nic), bridges, hubs, switches and routers. In addition to the Ethernet card may be requested. A common method used by the connection cable, optical cable, category 5. Microwave (as in IEEE 802.12), sometimes also used to connect these devices.

Network adapter

Network card, network card or network interface card (NIC to communicate with computer hardware) computer network. Physical access is provided by the device in a network environment. Most of the time, this is a low-level addressing system is a mac address. Repeater

Repeater signal noise, because of this, electronic devices, create and send a signal free from noise. Heavy duty remote wet signal may be subject to constraints without sacrificing performance. Academic development requires that more than 100 metres from the cable will also work in most twisted pair Ethernet configurations.

Hub

Copying more seaports axis at a later time without any changes by sending a packet to all ports on the hub. The destination address is not changed in the broadcast address.

Autumn

These ports are located on different network connections, network, with the exception of broadcasting never aired, which is the transfer of a copy of the door, but all of the MAC-address to certain ports that can be read.

Switch.

Turn off the filters for a piece of data packages for the MAC address of the port. Unlike the hubs by notification in the send port, the frames in all the ports that are connected to. A switch breaks up the collision domain, but is the field of broadcasting. Switching to the MAC address for the transfer of the frames. Each parameter is generally a large number of ports. This helps relieve the star topology of devices, networks and cascading additional options. Some switches are suitable for this routing.

Router

Network devices are routers route packets between networks. Packet redirection based on the information contained in the Protocol and forwarding table to the next router configurations are best for each package.
