Fundamental of computer science

To know the fundamentals of computer science, the focus has to be on the programming skills. For this one needs work on the following:


Programming skills
Operating systems
Computer organization
Algorithms and data structures
Programming languages
Problem solving techniques


This will help in developing strong programming skills.


Compilers and operating systems

Compiler is a program that results in object code after converting it as an input after taking it from source code. While the compilation process occurs the source code undergoes lexical analysis, intermediate code generation and also parsing, which is later on optimized to give object code as final output. Basically, it converts a programming language code to a machine-readable format.


OS or Operating System is a program that acts as an interface between computer hardware and computer users.  As a software all basic functions like management of files, process management, memory management and controlling peripheral devices like printers etc. are carried out. For instance: Windows operating system, LINUX operating system etc are good examples.

Information Theory

Information Theory can be defined as a scientific study of communication of information. One also needs to know how storage and quantification of information happens. It has greatly contributed to AI and deep learning.

Basic programming

BASIC or  (Beginners' All-purpose Symbolic Instruction Code) is simply based on ease of use. It is a high level language that enables the user to access simpler and consolidated data. Also, it is very useful for beginners as it lays emphasis on symbols.

Systems and architecture

In the world of computer science, the system architecture is structural design of systems. Also, in most cases it falls in the realm of Computer Engineering.

Software development and testing

The entire process of creating a software for end users keeping the requirements in mind is called software development. On the other hand “testing” is a phase where program execution takes place to find if there is a bug or problem.

Web applications and databases

Web applications run on a web server (with an active network) and are accessed through a web browser by a user. It is a form of application software. 

On the other hand, a repository of information that can be accessed fast and ensures integrity of data is called a database.

Computer design

Computer design is usually used to determine what hardware can be used and how each part should be connected overall. It is viewing the design from the perspective of the user.


Mathematical Foundations

Mathematical foundations are also known as foundations of math which is basically just the study of algorithmic, logical and/ or philosophical basis of mathematics. It is helpful for those who want to teach math to students with disabilities.

Computer Architecture And Computer Graphics

A set of rules and methods that can be used to describe the organization, functionality and implementation of computer systems is known as computer architecture. 
Computer graphics can be understood as a component of computer science which comprises creating and manipulating visual content.

Concurrent, Parallel And Distributed Systems

Concurrent programming / system incorporates arbitrary and dynamic patterns of interaction and communication.
Parallel computing / programming incorporates calculations / execution of processes that are carried out simultaneously.
Distributed programming / computing is to deal with nodes located at various locations on a network that communicate with one another and co-ordinate each one of their actions by passing across messages.

Computing, Computer Networks

Computing can be understood as an activity that is highly goal-oriented and requires the use and operations of computers.
A computer network comprises several nodes / computers connected with one another following a common set of communication protocols for the purpose of sharing resources and information.

Algorithms And Computational Complexity

An algorithm is both mathematical and digital in nature. It is basically a sequence of well-defined and implementable instructions that are used to solve problems and perform other different operations.
Computation complexity is defined by the amount and intensity of resources required to run a particular algorithm.

Models Of Computation, Computability And Decidability

Any particular model of computation specifically describes how a mathematical function is performed / computed to result in an output given a specific input.
Computability is the efficiency / proficiency / ability of a system to solve a problem in an efficient manner.
Decidability is the property of a problem corresponding to which an algorithm can be developed to solve it completely and correctly.

Design Of Computers And Operating Systems

Design of computers / computer designing concerns itself with the hardware designing of a computer system and its behavior and structure as experienced by the end-user.
An operating system is basically an interface that makes the hardware of a computer operational. It is a set of commands, software and interfaces that the human user interacts with.

Information Storage And Retrieval From Databases To Hypertext

Information storage and retrieval basically deals with representation, storage and access to information / data / documents. Information retrieval from database to hypertext is when that information is defined in non-linear / non-sequential text which is primarily an organized representation of that data.

Computer Networks And Security

A computer network is basically a network of nodes / computers / systems that follow a common set of communication protocols and information sharing.
Computer security is also known as cyber security which protects the integrity of the computers / network.
