Mobile Phone. How it works?
Mar 2nd
A mobile phone is an electronic device used for mobile telecommunications over a cellular network of specialized base stations known as cell sites. A cell phone offers full Duplex Communication and transfer the link when the user moves from one cell to another. As the phone user moves from one cell area to another, the system automatically commands the mobile phone and a cell site with a stronger signal, to switch on to a new frequency in order to keep the link.

SmartCards How it Works?
Feb 14th
A smart card, also called chip card or integrated circuit card is a type of pocket-sized card with embedded integrated circuits which can process data. This card can receive input which is processed by way of the ICC applications and delivered as an output. A smart card is a plastic card embedded with a computer chip that stores and transacts data between users. Smart card-enhanced systems are in use today in several key applications such as health-care, banking, entertainment and transportation. The card data is transacted via a reader connected to a computing system (more…)
Compact Disc. How it Works?
Feb 6th
A Compact Disc (CD) is an optical disc used to store digital data. CD-ROMs and CD-Rs remain widely used technologies in the computer industry.CD-ROM drives employ a near-infrared 780 nm laser diode. The laser beam is directed onto the disc via an opto-electronic tracking module, which then detects whether the beam has been reflected or scattered. (more…)
LASER diode – How it Works
Jan 28th
Laser is of prime importance in Optical memories, Fiber optic communications, Military applications, Surgical procedures, CD players, Printers etc. Various forms of lasers like Gallium Arsenide laser, Helium Neon laser, Carbon dioxide laser etc are used in various applications. CD players use laser technology to read the optically recorded data in the form of Bits and Pits on the CD. (more…)
Optical devices – How they work
Jan 27th
Electronic optical devices have varied applications in telecommunication, military services, medical field and in automated control systems. Solid state devices like sensors, IR and laser emitters are widely used in these applications. Optoelectronic devices use the energy from the sunlight to activate or inhibit electronic circuits. Check out how they work (more…)
USB – How things Work
Jan 26th
The easiest way to connect computer peripherals is through a Universal Serial Bus. The USB is a plug-and-play interface between the PC and the peripherals. The advantage of USB is that the device can be plugged in or plugged out without the need of restarting the PC. Here explains the working of USB. (more…)
