Explore how computer systems store, manipulate, and convert various data types like text, images, and videos through integrated software and hardware. Gain insights into accessible data representation.

Computer systems do not understand human instructions, nor can they perceive real-life data in its raw form. Therefore, computer systems require a way to store and represent information in an accessible way. They use software and hardware components combined to help retrieve information, store it, manipulate it, and convert it back to a human-accessible format. If you want to learn how computer systems perform complex tasks such as storing and manipulating textual data, videos, music, images of your cat, and much more, this course is meant for you.

Information Representation in Computer Systems

A file system is necessary to organize the files in memory so that the computer can differentiate between the files and easily access them. File systems usually consist of files separated into groups called **directories**. TA directory contains information about the files it stores, including their attributes, location and ownership. The directory is itself a file that is accessible at the start of the memory, as shown in Figure 2. 

 In this lesson, you will be introduced to the basics of file systems.
