what is computer science?

Computer science is the study of computation and knowledge. computing deals with the theory of computation, algorithms, computational problems, and therefore the design of computer systems hardware, software, and applications. computing addresses both human-made and natural information processes, like communication, control, perception, learning, and intelligence especially in human-made computing systems and machines. consistent with Peter Denning, the elemental question underlying computing is, What are often (efficiently) automated?

Sub Fields of Computer Science


Computer programming is the process of designing and building an executable computer virus to accomplish a selected computing result. Programming involves tasks such as analysis, generating algorithms, profiling algorithms’ accuracy, and resource consumption, and therefore the implementation of algorithms during a chosen programing language (commonly mentioned as coding). The ASCII text file of a program is written in one or more languages that are intelligible to programmers, instead of machine language, which is directly executed by the central processing unit. the aim of programming is to seek out a sequence of instructions that will automate the performance of a task (which are often as complex as an operating system) on a computer, often for solving a given problem. Proficient programming thus often requires expertise in several different subjects, including knowledge of the appliance domain, specialized algorithms, and symbolic logic.


Hacking is identifying weaknesses in computer systems or networks to take advantage of its weaknesses to realize access. Example of Hacking: Using password cracking algorithm to realize access to a system

Computers became mandatory to run successful businesses. it’s not enough to possess isolated computer systems; they have to be networked to facilitate communication with external businesses. This exposes them to the surface world and hacking. Hacking means using computers to commit fraudulent acts like fraud, privacy invasion, stealing corporate/personal data, etc. Cybercrimes cost many organizations many dollars per annum. Businesses got to protect themselves against such attacks.

Machine Learning

Machine learning (ML) is the study of computer algorithms that improve automatically through experience. it’s seen as a subset of AI. Machine learning algorithms build a mathematical model supported sample data, referred to as “training data”, to form predictions or decisions without being explicitly programmed to try to so. Machine learning algorithms are utilized in a good sort of applications, like email filtering and computer vision, where it’s difficult or infeasible to develop conventional algorithms to perform the needed tasks.


Hardware Engineering is the process of designing, developing, testing, and producing computer systems and various physical components associated with computer systems. With the arrival of technology and advances in R&D, the scope of hardware engineering has been expanded to incorporate hardware devices enabling embedded software engineering in non-computer devices.


Theoretical computing (TCS) may be a subset of general computing and arithmetic that focuses on more mathematical topics of computing and includes the idea of computation.


A network may be a group of computers that use a group of common communication protocols over digital interconnections for the aim of sharing resources located on or provided by the network nodes. The interconnections between nodes are formed from a broad spectrum of telecommunication network technologies, supported physically wired, optical, and wireless radio-frequency methods which will be arranged during a sort of network topologies.
