Computer Aided Design
Computer Aided Design (CAD) is the act of using computers to design an object. CAD techniques follow standard engineering design and drafting procedures, but use a computer to help speed up the process.

What is the best way to become a cad designer?
Gain a qualification in how to use CAD on a specific CAD course, or as part of an Engineering or Technology course. Then find any job, no matter how low paid, or how short in duration, where you will use CAD. You will then be employable as a CAD Technician and can later move up to become a CAD Designer.
Name 4 different specialized fields of drafting?
Mechanical, Electrical, Architectural, Civil, Aeronautical
What is the main work of transistors in an electronic circuit?
The main use of transistors in electronic circuits is as switches and memory storage
What is the standard size of Telecoms JC9C?
Inside dimension : 6' x 3' x 3' (L x W x D)
Heavy duty cover : 44" x 32" x 4" (L x W x T)
What is the difference between cad and auto cad and which one is better?
CAD is the generic name for all Computer Aided Design and Draughting software. Autocad is the most popular software provider.
What is the difference between direct data entry and indirect data entry?
Direct data capture is the collection of data for a particular purpose (e.g. barcodes being read at a supermarket so that the product can be identified or account details being read directly from the chip embedded in the credit card.)
Indirect data capture is the collection of data as a by-product from data collected for another purpose (e.g. using data collected from reading barcodes at a supermarket till to work out the stock levels or using data collected from reading barcodes to see whether an item is selling well.)
What is the difference between limit state method of design working stress method of design?
working stress: in this a structure is designed by considering the stresses in its working condition..
Limit state: In this the structure is designed by considering the stresses at different limit states. there are two limit states. ultimate limit state (situation in which structure collapse) and servicability limit state (situation in which cracks etc appears.)

What is Tab sequential format for CNC?
3.4.1 Structure of an NC Part Program
Commands are input into the controller in units called blocks or statements.
Block Format:
1. Fixed sequential format
2. Tab sequential format
3. Word address format
EXAMPLE:
Assume that a drilling operation is to be programmed as:
1. The tool is positioned at (25.4,12.5,0) by a rapid movement.
2. The tool is then advanced -10 mm in the z direction at a feed rate of 500 mm/min., with the
flood coolant on.
3. The is then retracted back 10 mm at the rapid feed rate, and the coolant is turned off.

What is a reprogrammable microcomputer?
A microcomputer is a small, relatively inexpensive computer having a central processing unit (CPU) made out of a microprocessor.[2] The computer also includes memory and input/output (I/O) circuitry together mounted on a printed circuit board (PCB).[3] Microcomputers became popular in the 1970s and 1980s with the advent of increasingly powerful microprocessors. The predecessors to these computers, mainframes and minicomputers, were comparatively much larger and more expensive (though indeed present-day mainframes such as the IBM System z machines use one or more custom microprocessors as their CPUs).
Advantages of using computer aided design in film making movies?
Computer aided design is not necessarily an appropriate tool for film making, unless there are structures required for the set that can be designed most economically using this tool.
A constant that multiplies a variable?
A constant that multiplies a variable is no longer a constant. By its very definition, a constant is something that can never be different. The result of variable multiplication is thus a variable, not a constant.
I would say that the above answer is not necessarily true. The common equation for the area of a circle is: area = pi * r2
The fact that you are multiplying the mathematical constant pi by a variable does not change the value of pi.
Agree with the second answer. Jsut to add, a constant that multplies a variable is called a coefficient.
How can represent digital and analog information?
Digital quantized information and analog is just information. Like the letter "i" on your screen is digital and made up of a few pixels= quantized. The letter "i" drawn on a piece of paper is not quantized = analog.
What is the term PS in engine power?
PS is a German unit for horse power.
This unit (German: Pferdestärke = horse strength) is no longer a statutory unit, but is still commonly used in Europe, South America and Japan, especially by the automotive and motorcycle industry. It was adopted throughout continental Europe with designations equivalent to the English horsepower, but mathematically different from the British unit. It is defined by the Physikalisch-Technische Bundesanstalt (PTB)[8] in Braunschweig as exactly:1 PS = 75 kilopond-meters per second(75 kp·m/s)×(9.80665 N/kp) = 735.49875 N·m/s ≈ 735.5 N·m/s ≈ 735.5 W ≈ 0.7355 kW ≈ 0.98632 hp (SAE)
The PS was adopted by the Deutsches Institut für Normung (DIN) and then by the automotive industry throughout most of Europe, under varying names. In 1992, the PS was rendered obsolete by EEC directives, when it was replaced by the kilowatt as the official power measuring unit. It is still in use for commercial and advertising purposes, in addition to the kW rating, as many customers are not familiar with the use of kilowatts for engines.
How can we find out First and follow in compiler design?
first:
1. If first character of production is terminal then becomes first.
eg. first(abAb)={a};
2.If a production of this type A->BCD...
means all are variable or non-terminal then
if first(B) donot contains null then
first(A)=first(B)
stop here.
else
then also check for next non terminal like C here
same as above step
and first(A)=First(B)+first(C).
if we get null stop there.
FOLLOW:
if you know first then you can easily go with follow.
1.if a variable is start symbol then follow=$.
2.if a production is of A->(any string1)B(any string2)
then
follow(B)=first(any string2) -{null}
3.if a production is of A->(any string)B
then
follow(B)=follow(A) .
stop
it is very simple, please try to understand!
really good answer, for more visit:www.cmail.99k.org
What is the distance between CPU and ups?
cpu means central processing unit.it is known as brain of the computer.it gives commands to monitor for any things.
ups means unintruped power supply if there is no supply in the house then it allows the computer for operating for 10 minutes
