Explore how data and information are represented in computer systems. Understand binary, hexadecimal, and the conversion processes.

Jul 16, 2021 · What is Data Representation in Computer? A computer uses a fixed number of bits to represent a piece of data which could be a number, a character, image, sound, video, etc. Data representation is the method used internally to represent data in a computer.

Mar 17, 2025 · Data representation can be referred to as the form in which we stored the data, processed it and transmitted it. In order to store the data in digital format, we can use any device like computers, smartphones, and iPads.

SECTION 1 COMPUTER SYSTEMS A – DATA REPRESENTATION AND COMPUTER STRUCTURE Fig 1.2 Extension cable with switch labelled with bits We will learn how the following types of data are represented in binary (as bits): Integers (numbers), Text, Images, Audio, Videos, Files, and Data for Transmission. We will discuss each in turn below. 1.

We will show you what puts the \digital" in digital systems and how computers process information. We will also teach you a few principles of cryptography, which allows us to make sure that information is kept secret or unaltered.

When you declare a variable in a program, Java allocates space for that variable from one of several memory regions. One region of memory is reserved for variables that are never created or destroyed as the program runs, such as named constants and other class variables. This information is called static data.

The course focuses on how programs and data are represented from the high level down to the low level. For programs, we examine (from high to low): abstract data types, Java code, C++ code, C code, assembly (x86) code, and a customized machine language.

Data Representation in Computers. Information handled by a computer is classified as instruction and data. A broad overview of the internal representation of the information is illustrated in figure 3.1. No matter whether it is data in a numeric or non-numeric form or integer, everything is internally represented in Binary.

Whether you're a GCSE, IB or A-level computer science student, our guide provides a detailed explanation of how data is represented in binary, hexadecimal, and ASCII formats, as well as the different types of data, such as integers, floating-point numbers, characters, and images.

Data representation, a fundamental concept in computing, refers to the various ways that information can be expressed digitally. The interpretation of this data plays a critical role in decision-making procedures in businesses and scientific research. Gain an understanding of binary data representation, the backbone of digital computing.
