Number system




Binary number system:

   Computers are the electronic machines which operate using Binary language. Binary system has only two digits to represent or construct entire number system. These digits are 0 and 1 are also called as ON and OFF or TRUE or FALSE. The base of binary number system is 2.

Decimal to Binary:

   To convert Decimal number to Binary simply we divide the Decimal number by 2 and extract the reminder, and co efficient again divided by 2 and extract reminder, repeat this process until the coefficient not able to divide with 2 (That means less than 2 (0 or 1)).

Example:

(225)10    =   (11100001)2  







Binary to Decimal:

   To convert Binary to Decimal number, first we write the binary number and list the powers of 2 from right to left, multiply with position bit and finally add, we get Decimal number.

Example:

1             1           1            0            0             0             0          1
27             26           25           24            23             22              21         20

128  + 64    +  32     +       0       +    0      +      0     +      0      +       1     =  225

Octal number system:

  Octal number system has only eight digits to represent or construct entire number system. These digits are 0, 1, 2, 3, 4, 5, 6 and 7. The Octal number system used in early main frame computers. The base of Octal number system is 8.

Decimal to Octal:

   To convert Decimal number to Octal simply we divide the Decimal number by 8 and extract the reminder, and co efficient again divided by 8 and extract reminder, repeat this process until the coefficient not able to divide with 8 (That means less than 8).

Example:

(225)10    =   (341)8






Octal to Decimal:

   To convert octal to Decimal number, first we write the Octal number and list the powers of 8 from right to left, multiply with position bit and finally add, we get Decimal number.

Example:

 3                4                1
 82                81                80                

192   +    32      +       1   =  225
  
Hexa Decimal number system:

  Hexa Decimal number system has 16 Symbols to represent or construct entire number system. These symbols are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E and F. The Hexa Decimal number system is 16.

Decimal to Hexa Decimal:

   To convert Decimal number to Hexa Decimal simply we divide the Decimal number by 16 and extract the reminder, and coefficient again divided by 16 and extract reminder, repeat this process until the coefficient not able to divide with 16 (That means less than 16).

Example:

(225)10    =   (E 1)16
 





Hexa Decimal to Decimal:

    To convert Hexa Decimal to Decimal number, first we write the Hexa Decimal number and list the powers of 16 from right to left, multiply with position bit and finally add, we get Decimal number.

Example:

 E (14)       1
  161            160

  224   +   1       =  225

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...

DS LAB FOR II YEAR

1.SINGLE LINKED LIST Procedure for creation of single linked list: STEP-1 : Declaring a variable named as “item”.Ie the element what we place in the linkedlist of the new node.         STEP-2 : Read the value   in “item”. Set first=last=null and next=null. STEP-3: Create a new node named as temp and assign the variable item to data part andassign Address of the node temp to null.       temp.data=item;       temp.next=null; STEP-4: Check   the address part of the first node Check if first=null Then assign first=last=temp Other wise Then assign the new node tolast.next=temp          last=temp STEP-6 : Repeat STEP-3 until you read required nodes. Procedure for display the linked list: STEP-1 : Check whether the list having nodes or not i.e Check if first=null        ...

LEVELS AND CURVES

LEVELS:                 Levels are used to set the shadows, mid tone etc.  O pen an image on Photoshop window. Select image menu on menu bar than adjustments than levels. A dialogue box will appear on screen which shows three pointers which indicates three optimum. The black triangle indicates shadows and gray triangle indicates mid tone and white triangle indicates highlights. In the channel menu different options are provided in drop down list. Make sure select on preview, which gives current adjustments on your picture. CURVES: Curves are to  similar to levels, it gives more power to control shadows highlights and mid tones. One of the simplest adjustment we can make with curves is increasing the contrast. Go to image menu and than adjustments,than curves. Dialogue box will appear on screen with straight diagonal line.      ...
