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

Selecting a vendor to supply your IT networking hardware often feels like trying to buy a used automobile in another country. The most difficult part may be choosing a brand from an unrecognizable set of manufacturers. There are many choices to make, and although the common reaction is to look for the cheapest price, we all know that there are many other factors which play important roles in good decision-making.

Selecting a Vendor of Hardware

The majority of large-sized vendors of hardware base their prices on not just the first purchase but on probable future purchases as well. It’s often possible to get better deals on today’s sale if the vendor can anticipate future sales and growth from your account. For this reason it’s a good idea to express your long-term goals to the vendor.

Your opt-in repair and service warranties are also important when selecting hardware for your network. Do you have a clear understanding of the services your vendor is offering in your location? For service at your location, what is the maximum distance technical support will travel? Are there extra costs associated, and do they outsource these services to another company? Phone-in technical support and warranty assurances are important, too. After making the initial purchase, what can you count on in terms of firmware, upgrades, and support. Find out in advance, and get it on paper.

Our practice has selected Dell. With good pricing, a life cycle for their product which lasts longer than we like to keep our hardware, it is a good match. Additionally, Dell offers onsite service in four hours for server and switch issues. There are volume discounts offered, so the more we purchase from them, the better our discount becomes.

After selecting a particular hardware vendor, your top decisions form several primary components

Switches - As the spinal cord of the network, this is where you’ll be plugging all the cables in. Selecting the right switch for your practice is dependent on the amount of traffic capacity you anticipate and the media used, be it fiber optic or cable. Often a network will have both copper cable and fiber optic, and in this case the switch will need to be set up to accommodate both.

Servers - Look for redundancy when selecting servers. Will a redundant machine swap power in the case of the failure of the other? Are there RAID drive arrays so the system won’t crash if the hard-drive does? How much RAM and how many processors does the server system have? More is better. Be sure to choose a backup tape drive device which is big enough to store your information and quick enough to back it all up during system down time at night. Try not to look past the physical setup of your hardware on the network. Perhaps a special housing unit or secure rack should contain the machines; this is particularly the case if you have a series of servers as many EMR system solutions do.

Devices for End-Users – Will you be using client terminals or real computers? Is the firmware able to be upgraded? If selecting thin client terminals, will they need a legacy port? For the exam rooms, will you be using an articulated arm? Our practices uses all of the above, and as a result we’ve come to an agreement about the minimum hardware configuration per device, be it desktop, laptop, server, printer or thin client. These choices have been based upon our expectations of performance. A physician must check in with the IT department before going out to buy a slick laptop computer, in order to be sure it will work well on the network. We examine the network every few months or so to keep in sync with the changes to our system and technology in general. This continual system of maintenance and improvement helps ensure optimal performance, streamlining the need for technical support.
