These  image size window contain different options which gives different size pictures as your requirements.


For setting height and width of the image first de-link the height and width measurements by selecting constrain proportions.

Set the units in terms of inches,centimeters, mm, pixels as your requirement. 72 is the biggest resolution for photograph on the units of pixels per inches (PPI).

 Auto resolution settings:


Photoshop provides the option to set the auto resolution which is little bit complicated to set manually.

Go to image size window click on auto .Auto resolution window will appear on screen.



This dialogue box contain three options .Drafts, Good, Best. Select anyone of the option from quality and finally click on ok.

Draft gives same resolution as your picture.

Good gives 1.5 time of it pre resolution.

Best gives 2 times of its pre resolution.

Characteristics of computers

    Characteristics:        All computers have similar characteristics, which tells how computers are efficient to perform task. Computers have some Limitations also. Speed:     Computer can work very fast. It takes only few seconds for calculations on very large amount of data. Computer can perform millions (1,000,000) of instructions per second.      We measure the speed of computer in terms of microsecond (10-6 part of a second) or nanosecond (10 to the power -9 part of a second).   Accuracy:        The degree of accuracy of computer is very high and every calculation is performed with the same accuracy.  The errors in computer are due to human and inaccurate data.       The calculation done by computer are 100% error free, If we provide accurate input. Diligence:        A computer is free from tiredness, lack of concentration...

Block diagram of computer

    The basic architecture of computer explained in Blocks is called Block Diagram of computer. This basic architecture of computer finally given by John V on Neumann. Thus it is also called  V on Neumann  architecture. It  is a theoretical design for computer that serves as the basis for almost all modern computers. Input Unit:      We need to input (fed) the data and instructions into the computers to process any task. The input unit consists of one or more input devices.      Keyboard is the one of the most commonly used input device. Other commonly used input devices are the mouse. Output Unit:     The output unit of a computer provides the information and results of a computation to outside world.        Printers, Visual Display Unit (VDU) are the commonly used output devices.   Storage Unit:      The storage unit of the computer holds data and in...
