History of Computer Science

Computers weren't always the sleek electronic machines we know and love. In fact, they weren't even always electronic. Originally, humans who performed computing tasks were called “computers”. As they were replaced by machines, the machines gained the title. Any machine that calculated numerical tasks was a “computer” in that it helped us compute things. Mechanical calculators appeared in the early 1600s, with a few different versions popping up in the following century. By the 1800s, they became powerful enough for use in office environments. Soon after, different forms of computation arose such as the use of punch cards.

In the early- to mid- 1900s, computer science as a field of study really grew its roots. The founding of the Watson Scientific Computing Laboratory by IBM and the close relationship with the associated university led to a focus on scientific research in the field. Thus, computer science as an academic discipline was born. Although it has only been around for less than a century, computer science has still contributed much to society. Following the Agricultural and Industrial Revolutions, it is said to mark the Information Revolution. That now puts us in the Information Age. More specifically, computer science has accomplished feats such as breaking the Enigma code, thus contributing to the end of World War II.

The history of the field is quite extensive and can't possibly fit here. But, you'll be able to find computer science articles in this category that further explore its development over time. These articles also go into more detail about the branches of computer science and their importance through the centuries.

All of the data you store online for doctors, memberships, banking, and more depends on it. You can read the computer sciences articles in this category to find out more about data and how it affects all of us.

On the aesthetic side of things, computer graphics and visualizations make things not only more visually pleasing, but also easier to navigate. A page of text is harder to comprehend than color coded table, diagrams, or organized layouts.

Computer Systems

Computer systems are the combination of software and hardware that make a computer useful for users. The area of computer science focusing on them aims to optimize them for various specific tasks, or just for general advances in performance.

Computer performance analysis lets computer scientists know how the system performs, and what can improve. Systems such as concurrent, parallel, and distributed systems can allow multiple computations to run simultaneously, increasing efficiency. Computer architecture, networks, security, and cryptography are other topics in this field.

Software Engineering

Software engineering focuses on the programs and operating information that a computer uses to run. In this field, computer scientists modify and improve software to make it efficient, effective, and affordable. This involves applying engineering practices to both create and manufacture new software, as well as organizing, analyzing, and maintaining existing software.

Underlying the practical objectives of computer science are the theoretical frameworks that support and develop them. Theoretical computer science gets more into the mathematical and abstract ideas about how data structures and algorithms work.

This area looks at questions concerning what exactly can be computed, and how. It also looks at the quantification of information to help us understand and optimize the compressing, storing, and communicating of data. These theoretical ideas eventually apply to all other areas as the foundations for new programs and methods.

Careers in Computer Science

Take advantage of these computer science articles to learn about and possible start a career in the field. You can read here about inspiring computer scientists to show you the possible leaps you can make in your own journey. Their careers stand out from others due to individual skills (and sometimes luck). If you're passionate and dedicated, you could end up in a similar position. But even average careers of normal people in computer science offer the opportunity to indulge in interests such as math, science, engineering, and even language learning.

As far as education goes, many computer programmers and software developers will need a bachelor's degree. However, some employers will take someone with an associate's. Computer and information research scientists, on the other hand, will likely need a master's. Overall these fields are growing in terms of the number of jobs available, and all make a median pay over 80,000 dollars per year (with research scientists making up to 118,000 dollars).

Prepare to need to know multiple programming languages, although most professionals will specialize in certain ones. All computer scientists should be able to think analytically for creating systems and programs, but also creatively with a detail-oriented mindset for coming up with out-of-the-box solutions to problems. Creativity also helps in one of the most booming markets out there at the moment: making apps and new gadgets.
