Smart Appliances

Sometime the minor things we normally do turn to give huge constributions at the end. The replacement of gas lamps with light bulbs using wires had never thought it would have brought us to these nonstop innovations. Our Great Grandparent installed wires to connect ligh bulbs replacing gas lamps but they never imagined that those very wires could be used to today's home appliances installation and power supply.

Few years to come (one or two) home network will be used for the purpose not yet imagined. Have you ever imagine controlling microwave oven or refrigerator via your cellular phone or computer? Well if you have not, it is time you do. Manufactures have already develop oven that will be cued remotely through cellular phone or Internet. These Smart Appliances will change your cooking plans. These smart appliance are programmable that means one can put the dish in the oven before going to bed and program the oven to cook the dish next day morning. Next day morning the oven will send a message to the cellular phone asking: "Do you still want me to cook". You then use your cellular phone or computer to instruct the oven.

With these Smart Appliances there will be no one rushing from the roads because He or She is late for the cooking or any other house rule.

Tips on securing private network

Many companies has took a step to centralise their network for the easy sharing of resources and to save some extra money. This is a good initiative on the business side of view, yet there is one important items sometimes forgotten when company decide to centralise the system and that is security of a network especially if it is a WLAN.

Most of the time network is set in the form of the followings
  1. Dial up connection
  2. Visual Private Network (VPN)

Though Dial up connection is not that expensive and easy to set I would advise you to consider using VPN because it is more secured. If your network is WLAN you need to set password to prevent unauthorised Users to access your network through i-spot.

The future of cablings

Is there a time where we will see cablings disappearing? I mean from twisted pairs (shielded and unshielded), coaxial and fiber optic cables. Let say for example LAN where there are fivety nodes (PCs), I think in this situation physical cables are needed because there are NICs which needs media connectors expecially if the network is Server Centric.

The above example clear the need of cabling but with the innovation of wireless settings like wireless home network(WHN) it time we try it out to save cable expenses.Though Windows XP Professsionals has builtin support for wireless technology with Service pack3 but this WLAN has some limitations for example it is ideal for laptops, allow temporally network and Users cannot access some of the resources.

In the next issue I will focus on the advantages of wireless settings range from:

  1. Wireless Personal Area Network (WPAN)
  2. Wireless Local Area Network (WLAN)
  3. Wireless Metropolitan Network (WWN)
  4. Wireless Wide Area Network (WWAN)
