The origins of computer science can be traced back to the early 20th century, when mathematicians and logicians began exploring the limits of computation. The pioneering work of Alan Turing, who developed the concept of a Turing machine, provided a theoretical model for computing that remains relevant today. Turing's work demonstrated that machines could simulate any process that could be described algorithmically. His ideas laid the groundwork for the development of modern computers and have had a profound impact on the study of algorithms and computation. The related RFC is RFC 792, which describes the Internet Control Message Protocol (ICMP) used in internet communication. https://en.wikipedia.org/wiki/Alan_Turing https://tools.ietf.org/html/rfc792
The formalization of computer science as an academic discipline occurred in the 1950s and 1960s, with the establishment of computer science departments in universities around the world. Early pioneers such as John von Neumann contributed to the development of computer architecture, leading to the creation of the von Neumann architecture, which serves as the foundation for most modern computers. Von Neumann's model included key concepts such as stored programs and sequential execution, which enabled computers to perform complex tasks by executing a series of instructions. The related RFC is RFC 791, which defines the Internet Protocol (IP), a crucial component of modern networking. https://en.wikipedia.org/wiki/John_von_Neumann https://tools.ietf.org/html/rfc791
During the 1960s, advancements in programming languages and operating systems were key areas of focus within computer science. Dennis Ritchie and Ken Thompson developed the C programming language and the UNIX operating system, both of which had a significant impact on the development of software and computer systems. C became one of the most widely used programming languages, and its influence can be seen in modern languages such as C++, Java, and Python. UNIX introduced important concepts such as multitasking, file systems, and user permissions, which have become standard features in modern operating systems. The related RFC is RFC 793, which specifies the Transmission Control Protocol (TCP) used for reliable communication on the internet. https://en.wikipedia.org/wiki/Dennis_Ritchie https://en.wikipedia.org/wiki/Ken_Thompson https://tools.ietf.org/html/rfc793
Computer science also played a key role in the development of artificial intelligence (AI), a field that explores the creation of machines capable of performing tasks that would normally require human intelligence. Early research in AI focused on topics such as symbolic reasoning and problem-solving, leading to the development of programming languages like LISP and Prolog. John McCarthy, one of the founders of AI, coined the term and contributed significantly to its early development. The field of AI has since expanded to include machine learning, natural language processing, and robotics, with applications in areas such as healthcare, finance, and autonomous systems. The related RFC is RFC 8452, which describes encryption algorithms used for securing data in modern systems. https://en.wikipedia.org/wiki/John_McCarthy_(computer_scientist) https://tools.ietf.org/html/rfc8452
Cryptography, another essential branch of computer science, focuses on securing communication and data through encryption techniques. Whitfield Diffie and Martin Hellman introduced the concept of public-key cryptography in the 1970s, revolutionizing how secure communication could be achieved over public networks. This concept led to the development of encryption algorithms that are widely used today to protect sensitive data and ensure the privacy and integrity of communications over the internet. Cryptography remains a critical area of research in computer science, particularly in the context of cybersecurity.

WHAT IS SOFTWARE ENGINEERING?
“A formal definition of software engineering might sound something like, “An organized, analytical approach to the software design | design, software development | development, software use | use, and software maintenance | maintenance of software.”
More intuitively, software engineering is everything you need to do to produce [successful software. It includes the steps that take a raw, possibly nebulous idea and turn it into a powerful and intuitive application that can be enhanced to meet changing customer needs for years to come. You might be tempted to restrict software engineering to mean only the beginning of the process, when you perform the application’s design. After all, an aerospace engineer designs planes but doesn’t build them or tack on a second passenger cabin if the fi rst one becomes full. (Although I guess a space shuttle riding piggyback on a 747 sort of achieved that goal.) One of the big differences between software engineering and aerospace engineering (or most other kinds of engineering) is that software isn’t physical. It exists only in the virtual world of the computer. That means it’s easy to make changes to any part of a program even after it is completely written. In contrast, if you wait until a bridge is fi nished and then tell your structural engineer that you’ve decided to add two extra lanes, there’s a good chance he’ll cackle wildly and offer you all sorts of creative but impractical suggestions for exactly what you can do with your two extra lanes. The fl exibility granted to software by its virtual nature is both a blessing and a curse. It’s a blessing because it lets you refi ne the program during development to better meet user needs, add new features to take advantage of opportunities discovered during implementation, and make modifi cations to meet evolving business needs. It even allows some applications to let users write scripts to perform new tasks never envisioned by developers. That type of fl exibility isn’t possible in other types of engineering. Unfortunately, the fl exibility that allows you to make changes throughout a software project’s life cycle also lets you mess things up at any point during development. Adding a new feature can break existing code or turn a simple, elegant design into a confusing mess. Constantly adding, removing, and modifying features during development can make it impossible for different parts of the system to work together. In some cases, it can even make it impossible to tell when the project is fi nished. Because software is so malleable, design decisions can be made at any point up to the end of the project. Actually, successful applications often continue to evolve long after the initial release. Microsoft Word, for example, has been evolving for roughly 30 years. (Sometimes for the better, sometimes for the worse. Remember Clippy? I’ll let you decide whether that change was for the better or for the worse, but I haven’t seen him in a while.) The fact that changes can come at any time means you need to consider the whole development process as a single, long, complex task. You can’t simply “engineer” a great design, turn the programmers loose on it, and walk off into the sunset wrapped in the warm glow of a job well done. The biggest design decisions may come early, and software development certainly has stages, but those stages are linked, so you need to consider them all together.
