This document discusses different types of files used in programming. It explains that there are two main types: text files, which are streams of characters that can be read sequentially, and binary files, which store data in binary format for more efficient storage and processing. Text files represent integer values as sequences of characters, while binary files store them directly in binary format, requiring less space. The document also reviews file paths and outlines the session on file types.

Files: A file is a collection of related information that is recorded on secondary storage
File path:
Relative path :relative path needs to be combined with another path in order to access a file
Absolute path: it is a complete path considered from root node

7. Types of Files
• Like c and CPP , python also supports two types of files
• Text files
• Binary Files

8. Text Files
• A text file is a stream of characters that can be sequentially processed by a computer in
forward direction
• They can read and write data one at a time
• Newline characters may be converted to or from carriage return/linefeed combinations
• A line can contain 0 or more characters (255)
• Write operation- newline converted to carriage return/ line feed
• Read- carriage return/ line feed to newline

9. Text Files
• Data representation: Internal , External
• Each file ends with special character called end of file (EOF)
• 123=2 bytes
• 123=3 bytes

10. Binary Files
• Binary file is a file which may contain any type of data, encoded in binary form
for computer storage and processing purposes
• Includes files such as word processing docs, pdfs, images, spreadsheets, zips and
other executable programs.
• Random access
• Follows internal representation
• Also ends with EOF marker
• Less space to storage
• Eliminates conversions between internal and external

11. Binary Files
• In a text file , an integer value 123 will be stored as a sequence of three
characters-1,2 , and 3.
• As each character takes 1 byte , therefore , to store the integer value 123, we need
3 bytes.
• However, in a binary file, the integer value 123 will be stored in 2 bytes in the
binary form.
• From this we can conclude binary files takes less space to store same piece of
data

12. E. Student’s evaluation of main body:
What is internal and external representation in files?
Which file type takes less space to store data?

13. Differentiate between Binary and text files

Summary
Types of files:
1)Text Files:
A text file is a stream of characters that can be sequentially processed by a computer in
forward direction
2)Binary Files:
Binary file is a file which may contain any type of data, encoded in binary form for
computer storage and processing purposes
