CD duplication is used for various purposes. It can be for back up or just for sale. In the process of CD duplication, many copies of same CD can be made. This is done without the replication process.
CD duplication the term itself means copying of CD. For CD duplication, the quantity is less than 500. In CD duplication, the quality is very good, it almost equals the original CD. The value of the CD is high too. The advantages of CD duplications are many, let us list down few:
• It is cheaper to duplicate the CD rather than using replication process, provided the quantity is low.
• In replication process you have to replicate a set number of CD’s whereas in duplication you can choose your quantity to do, it eliminates waste.
• Process of CD duplication is faster than CD replication. There are few disadvantages in using CD duplication, they are:
• The cost per CD is more in CD duplication than in CD replication.
• While copying the CD, there will be blue or black burn marks on the duplicates.
Whatever the case may be CD duplication, is most widely used process. It is very effective and time saving . Due to advanced technology, the quality keeps improving day by day.
Can we imagine the world without wires? For all the gadgets that we use at home there are wires connected to it. Bluetooth technology is the answer to it. Through Bluetooth, technology people can access low bandwidth without any wire connections. This advance technology wireless network does not use much power but is available for a short distance only.
Bluetooth is one of the most popular technologies being used in cell phones. Networking used by Bluetooth is very simple and it being wireless gives a tough competition to Local Area Network.
The nearest competitor of Bluetooth is infrared. Infrared has many additional features but it loses on one point with Bluetooth, as infrared rays cannot pass through the walls and other obstacles.
Bluetooth technology has a range of 100 meters and not necessarily is in sight. The power used by Bluetooth is very less and it works on overhead modus operandi. Due to these reasons, it is one of the best technologies available in the market.
Infrared technology is up in rate of data, Bluetooth has 1MBps whereas infrared has 4 MBps. Infrared is faster than Bluetooth technology.
If you think of security, Infrared is better as the data transfer is done only when it is in sight so the using of data by unknown people is not possible. In Bluetooth, technology range is higher and the frequency is open so it can be picked up any one making the security level very low.
Still Bluetooth remains to be one of the most popular technologies and will be for many years to come.
