Computer science is built on several foundations, including algorithms, programming languages, data analysis, and hardware. Algorithms are crucial, as they govern data manipulation, while programming languages allow translation into machine language. Data analysis and hardware provide a practical framework for computer science to operate. These fundamentals are essential for a complete understanding of computer science.
Computer science is a broad field that mainly deals with the storage, transfer and manipulation of information. There are several foundations on which the field of computer science is built. These computer science fundamentals include algorithms, methodology and programming languages, computing and data analysis, and symbols and computer hardware and elements.
Algorithms are extremely significant among the fundamentals of computer science. Most other aspects of computer science are based on algorithms. Algorithms are finite sets of instructions used to govern data manipulation. They are explicitly stated, step-by-step procedures for handling and processing data. Algorithms are usually written in the form of instructions or flowcharts rather than in the form of programmed computer code.
At their cores, machines understand only machine languages; as such, programming methodology and programming languages are important foundations of computer science. Computer programmers often translate algorithms—explicit, step-by-step instructions—into languages the computer can understand. Programming languages are artificial languages that computers can interpret to perform various calculations. A set of instructions expressed in a programming language is known as a program. C++, Python and Visual Basic are commonly used programming languages.
It is important for computer scientists to be able to apply their data manipulation skills to real-world tasks. The computation and analysis of data and symbols are topics that are essential practical foundations of computer science. This often involves analyzing, sorting, and drawing conclusions from vast amounts of information. This is especially apparent in fields such as computational physics and bioinformatics, in which physical and biological phenomena are observed and analyzed after numerous precise measurements.
All this manipulation, transfer and storage of data needs the means and place to exist and work. That place is in the hardware. The use of hardware is among the foundations of computer science as it provides a framework for all other aspects of computer science to operate on it. A program cannot operate without a hard disk to store it and a processor to run the complex algorithms it contains. Without a physical device to operate, computer science would be a purely theoretical field.
While these computer science fundamentals are just a few of the myriad topics covered by the broad field, they are the ones from which most other topics in the field begin. They truly are the foundations upon which the entire field is built. Without a basic understanding of these principles, one’s ability to fully utilize computers for processing and manipulation will be incomplete.
