Way back most families only had one single computer, and no other high tech devices. World Wide Web access was based on dial-up modems which were connected directly with a serial cable on the home computer. No Local Area Network was needed. The advancement of technology and the acceptance of modern high speed broadband connectivity at homes, necessitates that home appliances should be networked to facilitate online access and to also communicate and share information between them.

What I mean by home appliances is computers, gaming consoles, wired or wireless printers, and data storage devices like NAS. All of those devices need to communicated between themselves over a LAN, but also need to have high-speed access to the Internet. To achieve that, you will need to set-up a home network. With a home based network you are technically building a local area network, which can be wired or wireless, that networked devices communicate between inside the home, and also share the same internet connection.

The device that control the home network is the router. This is usually a device that lets you setup a wired or a wireless network. You can use Ethernet cables if you’re making a wired network, or use Wi-Fi for wireless. This router shares the internet connection with your devices.

Once you have your network in place, you have limitless opportunities to attach whatever you need to your network. Things such as laptops, desktops, gaming consoles, servers, print servers, etc After you successfully connect all your devices to the router, you can share and distribute your files over the network, have LAN parties on game consoles, play online video games, and share pictures between computer.

Electronic imaging consumes large amounts of bandwidth and data. Current connections to the home consist primarily of modems running at 33.6 Kpbs or 56 Kpbs. For those users who deal with still images and video, these speeds are not acceptable. The home needs fatter pipes in order to proliferate any kind of imaging services or if someone is trying to sell different types of imaging appliances that intend to use the Internet infrastructure. 

The home user has to contract with an ISP for a flat-rate monthly fee. The ISP usually provides a dial-up line that the consumer uses with s standard modem. The cost of  a dial-up line is usually under $20 a month. Many new technologies have been developed with the consumer in mind in order to increase the amount of bandwidth that will be available to a home computer.

The first hurdle you have to pass is to become more familiar with many of the letters and names. One the terminology is learned, the rest is just common sense and being able to carefully follow directions. One of the very first terms you will encounter, is the word ‘protocol’. The technical definition of the word as well as the acronyms can be very complex. However, for your purpose it is quite straightforward.

A protocol is a set of rules that have been adopted as a means for devices to communicate. For instance, the HTTP protocol used by Internet browsers specifies a detailed list of methods for passing Internet data back and forth. TCP/IP or Transmission Control Protocol/Internet Protocol is a method that dictates how packets get defined and transported on a TCP/IP based network.

Note that there are a variety of ways, involving other protocols, to establish networks and their rules. In days past IBM was one of the earliest with its SNA network philosophy. This was widely used in business for decades. Though it has now been replaced by TCP/IP, it is still in use throughout the world. These are not the only two that have been adopted at one time or another. While the details are only of interest to computer geeks and professionals, there are aspects that affect how a home network builder has to proceed. If you happen to know some of them, you will be able to choose your equipment and design your network intelligently.

For instance, if one of the central parts of the home network gear is the router. However, router come in a variety of types and each one is associated with a certain protocol. Wireless routers may use the 802.11b or 802.11g protocol. It is not important to know the technical definition, but you much know that the first is rated at 11 Mb versus 54Mb throughput impacts your network.

Even though the first is rated at 11 Mb, that is the rate under ideal conditions. The real throughput is approximately 6-7 Mb.  Also keep in mind that there are 8 bits per byte. That is equal to one character of data. So the actual rate is only just about 1/8th of what you actually tend to think of when you go to transfer files. Faster gear that follows the 802.11 standard running at 100Mb should soon be available.

However, most people do not have any reason to care about the details of Ethernet protocol. The standard protocol used in Ethernet networks is 802.3. This helps to do away with some of the strangeness from another cryptic number. It is also helpful to know that 10BaseT is like a synonym for wired Ethernet networks that run at 10 megabits per second. 100BaseT is the standard for cabled Ethernet networks that use equipment running at 100 Mbps.

Every week there will be a new acronym created as well as a new unfamiliar set of numbers. Network designers are among the geekiest in the business! However, if you familiarize yourself with a few of these protocols and related items, you will soon be barking them out with the best of them.
