Arithimetic and logic unit

The arithmetic and logic unit are note single entity but normally composed of two separate unit whose its operation is highly dependent  on the select input.                                                                                                                                   ARITHMETIC UNIT.Arithmetic unit this it takes the basic operation such as addition and substitution.The multiplication and the division operation are dependent on the basic operation and bit shifting.                                                                                                                        LOGIC UNITY. A logic unit this is the hardware unit which is implemented for performing basic operation such as OR,AND,NOT and NAND,A particular logical operation is selected using a ratio 4:1

Bits and bytes.

BITS.A are the binary digits and the smallest unit of storage in the computer.Simply can be defined as the shortened version of binary digits.Bits can have a 0 and 1 in it and a high (H) is represented by 1 and a low (L) usually represented by 0.                                                                                                                                                  BYTE.Is the amount of memory required to represent on one character.Simply can be defined as a group of bits.A byte with 8 bits in it can count from 0 to 255.Words are byte because they each have started number of bits in them.

RESISTOR

A resistor is a material that limits or resist the flow of current from one direction to another. It has two point of contact to which the resistor can be connected to an electrical circuit.                                     RESISTANCE.Is the characteristics of the resistor to oppose or indicates the measurement of current opposition,it is measured in ohm.Resistance is given by the ratio of voltage to current which is referred as an ohms law.                                                                                   OHM.This is the amount of resistance which is passes in one ampere of current when a one volt potential is placed across it.

THE ZENER DIODE

Zener diodes - Its a p-n junction diode in which runs in reverse bias condition when the voltage reaches the breakdown point. A stable voltage can be achieved by placing a resistor across it to limit the current.                                                   This diode is used to provide reference voltage in power supply circuits.These Diodes are specifically intended to make use of one or other of these break down(avalanche or zener breakdown) effect.                                                                                                                                                  When a zener diode is used it is operated at a reverse bias voltage which is slightly higher than its breakdown voltage.Under this condition the voltage across the diode is very nearly independent of the current through it.                                                                                                                       ZENER BREAKDOWN.This is the result of the electric field across the depletion layer becoming high enough to tear electron away from their nuclei and so produce a large number of electron hole pair.This has very marked effect on the number of minority carriers present and lead to massive increase in the reverse current.                   AVALANCHE BREAKDOWN.This it occur in diodes which have low level of doping.

CAPACITOR

Is an electrical component which is used to store energy by keeping electrical charge on their plates.                                                                                                                                                 When the negatively charged conductor is connected on the ground,the negative charge flow from the conductor to the earth similar a positively charged conductor would receive an electron from the ground,                                                                                                                                               These electron flow because of potential different between the conductor and the earth.Consider the electrical device like Radio when the power is switched off the power lamp fades out slowly and the stereo has its sound playing for some second after power is switched off,This is because the electrical energy is being stored in these devices and as the result the electronic appliances then continued to being supplied with it.                                                                                                                                                  Capacitor is mostly used in computer,radio and other electronic devices.A full charged capacitor has a positive charge on one plate and an equal negative charge on the other side.                                                   CAPACITANCE.Is the ratio between the charged conductor and the potential difference across the plates of the conductor.                                                                                                                                                       TYPES OF CAPACITOR                                                                                                                 There different types of capacitor as explained below                                                                                                                                      1.VARIABLE CAPACITOR.In this variable capacitor air form the insulating material so the capacitance of such a device is altered by changing the overlapping area between the plates and its mostly used in tuning the radio sets.A variable capacitor its also known as air filled capacitor this because the semiconductor plates are separated by air.One sets of plates is fixed while the other one rotate.                                                                                                                                            2.MICA CAPACITOR.Is the type of capacitor in which the sheet of metal foil are separated by the strips of mica.Mica is preferred because of its nature in mineral and split easily into very thin sheet                                                                                                                                             3.PAPER OR PLASTIC CAPACITOR Is types of capacitor which have metal foil strips as their conductor.Waxed paper form the insulating material and the polyester film can also be used as the separating material which are rolled up together and sealed up inside a metal box so as to moisture from entering.
