What is LED?what is electronics?what is transistorwhat is CDMA ? why your are using this technology ? tell me?

Question

PLEASE TELL ANSWER

Answer 1

too much questions...  you are just for wasting this site.

Answer 2

We are using this technology because we are not fools.  Hope you got it now.

Answer 3

LED--->Light Emitting Diode ...is a semiconductor diode that emits light when an electrical current is applied in the forward direction of the device.LEDs are widely used as indicator lights on electronic devices and increasingly in higher power applications such as flashlights and area lighting.The color of the emitted light depends on the composition and condition of the semiconducting material used, and can be infrared, visible, or ultraviolet.

Electronics--->is the study of the flow of charge through various materials and devices.Mixed-signal circuits refers to integrated circuits (ICs) which have both analog circuits and digital circuits combined on a single semiconductor die or on the same circuit board.

CDMA-->Code division multiple access is a channel access method utilized by various radio communication technologies.One of the basic concepts in data communication is the idea of allowing several transmitters to send information simultaneously over a single communication channel. This allows several users to share a bandwidth of frequencies. This concept is called multiplexing. CDMA employs spread-spectrum technology and a special coding scheme (where each transmitter is assigned a code) to allow multiple users to be multiplexed over the same physical channel.

Answer 4

You are also using this technology to ask your question !  So why are you using this technology.

Answer 5

LED's is a semiconductor diode that emits light when an electrical current is applied in the forward direction of the device, as in the simple LED circuit.

Electronics is the study of the flow of charge through various materials and devices such as semiconductors, resistors, inductors, capacitors, nano-structures and vacuum tubes. Although considered to be a theoretical branch of physics, the design and construction of electronic circuits to solve practical problems is an essential technique in the fields of electronic engineering and computer engineering.

Code division multiple access (CDMA) is a channel access method utilized by various radio communication technologies. It should not be confused with the mobile phone standards called cdmaOne and CDMA2000 (which are often referred to as simply "CDMA"), that use CDMA as their underlying channel access methods.

Answer 6

I found all of these answers on Wikipediea in less than a minute, try doing some research before you ask a question, use the information and make your own conclusion why we use them.
