1. Resistor: Its frequency is ohms. It is used to reduce the voltage. It has nine types of Colours. It oppose both the A/C and DC Voltage. If the Voltage is passed means the Resistor will act. If not the Voltage will not pass.
2. Capacitor: Its frequency is fereds it is the highest. The lowest frequency is lowest. It allows A/c and it blocks the DC Current. The Capacitor has conductor and insulator. The Conductor it allows the electricity. The insulator it does not pass electricity.
3. Current: It is nothing but power supply. Two types of Current A/C and D/C
4. Voltage: Two types of Voltage A/C and D/C
5. Coil: It is used to remit some voltage only if there is any magnetic. If the magnet is there means the magnetic field will bouch the coil and then the voltage will be formed in a coil. It is nothing but to remit some Voltage.
6. Transformer: It is nothing but the coil according to the activation of it.
7. Diode: The Diode is nothing but emiting lights positive(+) and negative(-). It has anode and cathode. It allows Dc and it oppose A/C according to the frequency of it. There are three types of Diode.
a) dennel Diode
b) Led Diode
c) Tunnel Diode.

Problmes if dead set occurs:
If we switch onn the cell phone switch if it does not get any voltage means first we should check up the battery is there or not, if battery is there means we should check it off the voltage of the battery the voltage is should be around 3.7, voltage and then if the voltage is in condition of the battery means. We should check it of the pin of the battery if the pin is stuck in any lid means it should be clearly taken it and then we should switch onn the cell phone. If the battery and the battery conector is perfect means check it off the Power Ic. Whether the Power Ic is sending three types of voltages to all the circumstances.
The three types of Voltages are
VBB, VCore, V+O,
The VBB Voltage goes to the Flash, Ramand Cpu the voltage is around 2.7 Voltage. Then check the Vcore Voltage it voltage is around 1.9 Voltage. Then check the V+O, Voltage it supplies the voltage to Crystal around 2.7 Voltage and IC Supply 26MHZ. If there any condition has not worked means there will be some fault in this continuation. If all three conditions is ok means then theree will be a fault in CPU. In there are the cell phone cannot be worked.

1. Message Directory: Were the message consists of create message, inbox, outbox, send items, saved items, message recipt, message settings etc.
2. Phone Directory: These phone directory consists of missed call, received call, dialled numbers, Phone directory settings and etc.
3. Contact directory: This contact directory is only for the adding of contact members for your purpose. This contact also have a limitation if it cross the limtiation the contact members cannot be added.
4. Settings: This is the main part of the mobile phones, were to change the setting of the phones to any mode and the theme etc.
These 4 menus is the main role for the mobile phones to process without these four menus the company will not launch any software for their purposes. This are all the major menus of mobile phones.

How to Buy a Good Mobile Phone:
There are many ways of finding a good mobile in a market area. Bcoz, nowadays the mobile phone company is most and more developed in all over the world. Many new companies are also developed in the country. The mobile phone shape and the menus of the mobile phone will be differ from company to company and the shape of the mobile phone will be differ from mobile to mobile itself.
The steps to buy a good mobile phone: Before buying a mobile phone, check whether the mobile phone is an company product, whether it has an guarantee period, and whether it is still not opened a seal by the others. If the seal is opened return back to the dealer and get the other piece of mobile phone which is still sealed. Say the dealer to open the seal in front of the customers and check whether all the parts of the key pad is working and the lcd light is working and whether the menus of the mobile is correct and whether it is fast. Then ask the dealer to insert a dummy sim card to check whether the display of the mobile is in clear and clearity is gud. Then the IMI number of the mobile phone should be written in guarantee sheet also and there are some kinds of short cut keys to know about the IMI number of each and every mobile phones, this IMI number will vary from mobile to mobile. So this IMI number is the main to find the lost of mobiles due to only by the IMI numbers.
These are all the steps to be done before buying a good mobile phones.

In each and every country the cell phone companies is famous and familiar to the peoples in the country and this cell phone companies launches many different kind of cell phones daily. But the make and rate of the cell phone differes from company to company and country to country also in some times. The original cell phones can be given guarantee with the acknowledgement copy. The usage of cell phones are
1. It is used to communicate at any time to any country
2. It is the easy method of communication of peoples from one country to others country.
3. The cost of call and the times of the manpower is also very less.
4. The cost of calls will be varied from one country to other countries according to the sim card usage.
This are all the main usage of cell phones in our day to day life.

This are all the main usage of cell phones in our day to day life.
The Circuit Board:
The circuit board consist of thick and green colour plasic coded, it is not easily burnt. This circuit board has many pathways to send a voltage to one part to other parts in the circuit board. This circuit board only plays a vital role to cellphone to work bcoz the voltage from one parts of the spares will send to the others parts of the spares it all occurs only due to the help of circuit board path ways. This path will varies from board to board and companies to companies also. This circuit board is a rough and light weighted one and it cannot be burnt easily it is a washable board with the help of petrol or white petrol to keep the circuit board clean and neat for the voltage to circuit easily without any disturbances in the circuit board.
If cell phone gets problem it will be having a steps to identify the problem of the cell phone. If the problem was not found then directly clean the circuit board gentrly with petrol and keep it for dryness and then fix it in the cell phone. The 60% of the problem will be solved with this kind of method. The remaining 40% of the problem will be solved only by checking each and every parts of the circuit board only.This are all the main features of circuit board vital role in the cell phone.

The usage of Keypads:
The keypads is used to dial a number and to type a message and to operate the mobile. Without the keypads cell phone will not be made by the companies. Nowadays, the keypads are mainly converted into touchscreen systems. This systems is also easy as the keypad method. This touchscreen system is used to operate only by the stick which is provided by the companies with the soft corner which is rotated with the help of smooth sponch which is to prevent some scratches int he display of the cell phone.
This touch screen also has the same menus and the same usage of what the keypads done to operate the cell phones. If the key pads is not in the condition to seat in the body of the circuit board the particular number will not be displayed until or unless it is placed in the correct location to work it properly otherwise the single number will be making the others to get irritated to work. This are all the usage of keypads in the cell phone. This key pads is also different from each and every companies the font of the button and size of the button will also varies from each companies. But nowadays we can select any languages from any mobile according to the company make.

The major problem keypad occurs:
Sometimes the key pad some button will not work proplery it will work only if it pressed hardly. Actually keypad should be used softely this hard touch key pad will make the circuit board to get spoiled and the pathway of the circuit board will also get squashes due to some reasons. The major problems what key pads occurs:
1. Some of the keypad button did not work: To solve this problem remove the panel from the body of the cell phone and clean the key pad gently with the cloth and the connection of the keypad to the circuit board should be also cleaned gently by using petrol or white petrol neatly. This kind of things will itself make the key pad to work smoothly.
2. The key pad is gud but some buttons not working: To solve this problems take the panel from the cell phone and each and every button faces in the circuit board and each and every buttons will have a connectivity to the other buttons and finally this connectivity goes to the main spares in the circuit board. So, Check whether the main parts of the body receives voltage and if it receives the voltage whether it supplies the voltage to the connectivity of the button places. Then do the further steps to work it properly.

The usage of pannels:
The pannel of the cell phone differ from company to company and also to the model of the companies also. Some companies make have a same software program but this pannels will be changed to all the models. Each and every models will have a different pannels which is to suit the body of the cellphone. This pannels is used to cover the body of the cell phone and to prevent water to get in easily. This are all the main usage of pannels used for the cell phones.
