A Modem generally modulates digital outgoing signals from a computer or other digital device to analogue signals for network communication. It turns analog signal to digital signal and digital to analogue signal.
This is actually very important for computer or other device’s communication. It was called Data phone in past. Modem became most common and popular for home users when Dennis Hayes and Dale Heatherington released the new 80-103A Modem in 1977. They developed it much. Actually Modems are referred to as an asynchronous device which means the device transmits data in an intermittent stream of small packets. It makes pc or other devices [...]
GPS means Global Positioning System which is a network of satellites that send details of their position from space to earth. GPS work. The signals are leaded by GPS receivers such as navigation devices.
They are actually used to measure the exact position, speed and time at all. It is an part and parcel technology in the modern world. GPS is well-known for its military uses. It was first developed by the US to help in its global intelligence efforts at the height of the Cold War. At first GPS system was developed in the 1960s to allow ships in the US Navy to navigate the oceans more accurately.
How to use GPS?
There are many [...]
GPRS means General Packet Radio Services which is a packet-based wireless communication service that promises data rates from 56 up to 114 Kbps and continuous network connection to the Internet for mobile phone and computer users.
The higher data rates provide users to take part in video conferences and interact with multimedia Web sites and similar applications using mobile handheld devices as well as notebook computers. GPRSis dependent on Global System for Mobile communication. The main complements existing services such circuit-switched cellular phone connections and the Short Message Service are leaded byGPRS.
GPRS packet-based services that cost [...]
Many of our visitors has asked me to know what is Bluetooth? for this in this article, I have tried to discuses about Bluetooth in brief. Bluetooth is a wireless technology that is used to be aimed at simplifying communications in low ranges among Internet devices and between devices.
It is usually used to simplify data synchronization between Internet devices and other computers. Actually Bluetooth is the part and parcel of a mobile device to share any data from one to another device. The maximum range of Bluetooth is 10 meters. Data may be exchanged at a rate of 1 megabit per second with the help of Radio wave Technology. It has Built-in encryption. Verification must be [...]
