Writing String to Binary file • To store string in binary file, we must convert it to binary format either by prefixing the string with ‘b’ or using the encode() function. • For e.g. VINOD KUMAR VERMA,PGT(CS), KV OEF KANPUR & SACHIN BHARDWAJ, PGT(CS), KV NO.1 TEZPUR We can use ‘a’ in place of ‘w’ for append

binary number system is used in Morse code – a method of communication over long distances that has been in use for more than 100 years, and still in use today. The binary number system can be used to represent numbers as sequences of zeros and ones. The basic element of a binary number system is a bit, which can take the values 0 or 1.

4. To write all the binary numbers from 0 to 31, you need to add one more column(to the left) to the imaginary columns that make up the Binary Number column of table 3 (see question 3) and continue the pattern you described in question 3. Create the table, similar to table 3, that shows all binary numbers from 0 to 31. 5.

But, neither binary nor decimal is particularly convenient to write out bytes (binary is too long, and decimal isn't numerically friendly for byte representation) So, we use "hexadecimal," (base 16). ... You can also use Python to convert to and from binary: (but you should memorize this as it is easy and you will use it frequently)

consider 0.375, the fractional part of 12.375. To convert it into a binary fraction, multiply the fraction by 2, take the integer part and re-multiply new fraction by 2 until a fraction of zero is found or until the precision limit is reached which is 23 fraction digits for IEEE 754 binary32 format. 0.375 x 2 = 0.750 = 0 + 0.750 => b −1 = 0 ...

binary (400 bytes) and file header (3200 bytes). A simple view of a SEG-Y file (Figure 1, below) shows it starts with a 3200-byte textual (human-readable) block. It then has a 400-byte binary (not human-readable) block. Next, the file has trace header and trace data pairs that extend to the end of the dataset. Each trace header has 240 bytes.
