Electronics

1. Is the use of electric current to control, commuicate and process info

   • any information can be transformed in a signal there are two types of electric signal
     • analog signal
       • a current is varies smoothly to represet info
     • digital signal
       • pulse of current are used to represent info, it carries the info on pulses or steps

2. semiconductor devices

   • its a material than can conduct better current than an insulator but not as a conductor
     • two types semiconductor combined can create diodes, transitors and integrated chips
       • Diode is a combination of a n-type and a p-type
       • Transitor is a combination of three layers of semiconductors
       • Integrated circuits are individual componets join in a group

3. electronic communication

   • telephones
     • is the most used device for communication
       • its main parts are
         • Dialing Mechanism
         • Transmiter
         • Reciever

4. Sound Recording

   • also commuicate imformation using electronic signal
     • CD
     • Stereos
     • Radio
