To the home user there’s a great number of networking gear on sale. Specifications and the naming of these devices can be confusing to the newcomer. This guide was created to cut through all of the jargon and clarify names, the terms and specifications making it more easy to make the right choices when setting up a house or small office network.
What’s a Network?
A network typically includes multiple computer apparatus which can communicate with each other enabling the sharing of data or information between them. With the current technical progress networks aren’t restricted to computers and notebooks as they’ve extended to stereo equipment, televisions and even mobile devices like cellphones and tablet PCs.
Before the improvements in wireless technology networks would mostly be “wired”. This would call for various apparatus between computers that will enable cables to be plugged into the machines empowering communicating. These cables on home networks would be impractical as it would normally require the drilling of holes as well as would restrict the motion of the apparatus.
In the past few years wireless networking has enhanced and now works at speeds that permit networking of gear much more readily than ever before and faithfully.
Network speeds are significant when determining which way to go when constructing a network for the office or home. Wired networks now run at three speeds. All these are measured in Megabits Per Second, the present speeds are 100Mbps, 10Mbps and Gigabit which runs at 1000Mbps. As it cannot actually make do together with the transport of information needed by the current applications and file sizes, 10Mbps is quite old in the current networks. 100Mbps typically take up lots of network bandwidth and may continue to be okay provided that there isn’t much multimedia conditions as these files are big.
There are now four wireless standards to be used throughout the office or home, 802.11a, 802.11b, 802.11g, or 802.11n. The initial two standards 802.11a and 802.11b are quite slow and also quite insecure to the stage where they shouldn’t be used on networks at all. 802.11g works at 54Mbps and is still useable on networks. It manages the transport of information at home or at work and will function satisfactorily when browsing the web. 802.11n is the latest standard to be introduced and can work at speeds up to 100mbps. This is actually the standard which should be executed if using wireless networks.
Wired networks need network cables or special cables to work. The notebook computer or network gear must have a network interface to empower these cables to be joined to them. The interface is known as an RJ45 interface. There are a few kinds of network cable that may connect network these are CAT5e, CAT5 and CAT6 cables. As this can manage all network speeds including Gigabit 1000Mbps speeds for many uses the CAT5e ought to be utilized. Notice that CAT5 doesn’t support Gigabit networking.
A network switch is utilized to connect multiple computer apparatus using network cables. They often have a number of RJ45 interfaces used to connect the apparatus to the switch. They are able to come in a variety of sizes and have a differing number of interfaces builtin. A network switch can have as very little as four interfaces for small or home office use nevertheless additionally they can come with 16, 8, 32 and 48 interfaces, clearly the bigger switches are often found on bigger company networks.
Some switches come with a management interface which may be obtained by means of a web browser permitting settings that are specific to be controlled in the switch for example disabling and enabling interfaces. It will enable segmenting of the network however this really isn’t generally a prerequisite for small and home office networks.
The purpose of the network router would be to route traffic around a network, as the name implies. They analyse it and choose the information being transmitted across the network and send it to the necessary destination.
Usually a home router handle the passing of information between these devices and yet the web through the modem and will interface with all the many network gear throughout the house. Before the common use of contemporary routers, internet connection sharing between multiple apparatus was extremely treacherous and long winded. Today many ISPs (Internet Service Providers) provide a router as a portion of their setup or bundle.
A router could also have wireless technology built in enabling the connection of wireless devices to the network. These wireless apparatus subsequently possess the capacity to share and access resources on the network via an identical router.
An average home router will have four RJ45 ports, a port for connecting it to the wireless and web capabilities enabling it to become the central networking device throughout the house.
Network Attached Storage
NAS or network attached storage was just used to save information shared amongst devices on the network for company. There are apparatus designed to do this for home use. The network attached storage is essentially one or more hard disk drives found in a carton which interfaces with the home network by means of a cable. These are able to be linked to the router or switch. They’ve an interface which can be obtained by a web / internet browser backing up etc. and enabling straightforward settings These devices are accessed by computers, notebooks etc using builtin networking enabling browsing, copying of files to and from the network attached storage right.
