These contain instructions that can be directly accessed by the CPU.

2. A 40-pin connector that connects computers and hard disk drives.

Reador write information on magnetic or optical storage media.

4. Sometimes referred to as removable drives and can be used on multiple.

An interface that can connect both internal and external drives.

Work through all the steps in your chart to make sure they are clear and exhaustive, and that there is no open-ended node remained.

It indicates the beginning or end of a flowchart.

8. This is the most common component of a flowchart.

It shows a step that decides the next step in a process. Commonly,this is a yes/no or true/false question.

It shows the process’ direction. Each flow line connects two blocks.

An optional step here is to style your chart with different shapes and

color to make it easier to follow.

12. Flowcharts should be made easily accessible to all parties involved.

. It represents an individual step or activity in the process.

It shows where an in-process measurement occurs.

15. It is a mark, sign, or word that indicates, signifies, or is understood as representing an idea, object, or relationship.

A letter designation is written near or beside a symbol to indicate what type of component that symbol is. The letter designation for transistor is

These types of lines are used to show mechanical linkages between components or parts of components on schematic diagram.

This punctuation mark is used to show the destination of grouped interrupted lines in a diagram.

It is a special table with a slanted surface that can be adjusted based on the desired angle.

20. It is used to equally divide a line or space by trial and error.

If the Greek Letter Omega (Ω) appears in a schematic diagram, the component value being represented is a

22. The labels of a capacitor C1A and C1B in a diagram are examples of

One of these is NOT given in a schematic diagram

A. Wiring specification                    C. Actual appearance ofcomponents

B.Point-to-point resistance values   D.Operating instructions

The symbols on a schematic diagram are arranged so that thediagram can be “read” in this manner.

Line conventions is use in drawing electrical and electronicsdiagrams.

Resistors are components used to resist the flow of electric current and have a stated value of resistance.

To determine the resistance of a resistor, you can use the Color Coding or directly use the multi-tester.

Resistors can be fixed or variable.

The “left-hand” or the most significant colored band is the band which is nearest to a connecting lead with the color- coded bands being read from left-to-right.

The fourth and fifth bands are used to determine the percentage tolerance of the resistor.

Resistor tolerance is a measure of the resistor’s variation from the specified resistive value

Typical resistor tolerances for film resistors range from 1% to 10% while carbon resistors have tolerances up to 50%.

Resistors with tolerances lower than 2% are called precision resistors with the or lower tolerance resistors being more expensive.

Resistors regulate the amount of current flowing in an electronic circuit.

Resistors must be properly sized and intact to perform these functions.

An attempt to measure a resistor that is still connected to the circuit can yield an incorrect calculation.

If the resistor shows signs of blackening or charring, it may be damaged by excess current flow.

Resistors have no polarity, so it does not matter which DMM lead is connected to which resistor leg.

Larger resistors may have their value indicated by color coded bands.

A capacitor is an electronics/electrical component that stores energy in the form of Electric Charge.

Capacitors are often used in electronics circuit boards or few electrical appliances and perform a variety of functions.

Darkening on the PCB or casing around the contacts of a capacitor means it is no longer suitable to use.

Transformers are an electrical component that transmit electrical energy between at least two circuits.

Transformers regulate the voltage in circuits.

Step up transformer increases the output voltage.

Step down transformer produces the same amount of voltage as the input voltage.

If the expected voltage is not present on the secondary testing, either the transformer or a filtering or shaping component is bad.

If the testing of the filtering and shaping components show no problems, then the transformer is bad.

A diode is a small device that allows an electric current to flow through in only one direction.

Discharging the capacitors to get rid of any extra voltage they hold will decrease your risk of an explosion or electric shock.
