Computer science is no more about computers than astronomy is about telescopes. Edsger Dijkstra Computer science is not as old as physics; it lags by a couple of hundred years. However, this does not mean that there is significantly less on the computer scientist's plate than on the physicist's: younger it may be, but it has had a far more intense upbringing! Richard Feynman http://www.wordiq.com CompSci 6 : Spring 2005 1.2 Scientists and Engineers Scientists build to learn, engineers learn to build – Fred Brooks CompSci 6 : Spring 2005 1.3 Computer Science and Programming Computer Science is more than programming The discipline is called informatics in many countries Elements of both science and engineering Elements of mathematics, physics, cognitive science, music, art, and many other fields Computer Science is a young discipline Fiftieth anniversary in 1997, but closer to forty years of research and development First graduate program at CMU (then Carnegie Tech) in 1965 To some programming is an art, to others a science, to others an engineering discipline CompSci 6 : Spring 2005 1.4 What is Computer Science? What is it that distinguishes it from the separate subjects with which it is related? What is the linking thread which gathers these disparate branches into a single discipline?

Systems Development Life Cycle
Systems Development Life Cycle From Wikipedia, the free encyclopedia Jump to: navigation, search For other uses, see SDLC (disambiguation). Model of the Systems Development Life Cycle with the Maintenance bubble highlighted. The Systems Development Life Cycle (SDLC), or Software Development Life Cycle in systems engineering, information systems and software engineering, is the process of creating or altering systems, and the models and methodologies that people use to develop these systems. The concept generally refers to computer or information systems. In software engineering the SDLC concept underpins many kinds of software development methodologies. These methodologies form the framework for planning and controlling the creation of an information system[1]: the software development process.

Any SDLC should result in a high quality system that meets or exceeds customer expectations, reaches completion within time and cost estimates, works effectively and efficiently in the current and planned Information Technology infrastructure, and is inexpensive to maintain and cost-effective to enhance.[2] Computer systems are complex and often (especially with the recent rise of Service-Oriented Architecture) link multiple traditional systems potentially supplied by different software vendors. -
Programmable Digital Microcircuits - a Survey with Examples of Use
- 237 - PROGRAMMABLE DIGITAL MICROCIRCUITS - A SURVEY WITH EXAMPLES OF USE C. Verkerk CERN, Geneva, Switzerland 1. Introduction For most readers the title of these lecture notes will evoke microprocessors. The fixed instruction set microprocessors are however not the only programmable digital mi• crocircuits and, although a number of pages will be dedicated to them, the aim of these notes is also to draw attention to other useful microcircuits. A complete survey of programmable circuits would fill several books and a selection had therefore to be made. The choice has rather been to treat a variety of devices than to give an in- depth treatment of a particular circuit. The selected devices have all found useful ap• plications in high-energy physics, or hold promise for future use. The microprocessor is very young : just over eleven years. An advertisement, an• nouncing a new era of integrated electronics, and which appeared in the November 15, 1971 issue of Electronics News, is generally considered its birth-certificate. The adver• tisement was for the Intel 4004 and its three support chips. The history leading to this announcement merits to be recalled. Intel, then a very young company, was working on the design of a chip-set for a high-performance calculator, for and in collaboration with a Japanese firm, Busicom. One of the Intel engineers found the Busicom design of 9 different chips too complicated and tried to find a more general and programmable solu• tion. His design, the 4004 microprocessor, was finally adapted by Busicom, and after further négociation, Intel acquired marketing rights for its new invention. -
H&P Chapter 1 Supplement: but First, What Is Security? Assets
H&P Chapter 1 Supplement: Introduction to Security for Computer Architecture Students https://doi.org/10.7916/d8-7r78-2635 Adam Hastings Mohammed Tarek Simha Sethumadhavan October 1, 2019 For decades, the role of the computer architect has been to design systems that meet requirements, defined primarily by speed, area, and energy efficiency. However, as humans become more and more reliant on computers, it becomes increasingly obvious that our specifications have failed us on one key design requirement – Security, – as evidenced by nearly weeklynews of high-profile security breaches. In the face of such damaging consequences, it becomes clear that the security of our technology must no longer be relegated as an afterthought, but must be a first-order design requirement, from the very beginning—security must be “built-in” rather than “bolted on”, so to speak. In particular, it becomes important, even necessary, for security to be built into the lowest levels of the computing stack. It is for this reason that security must become a fundamental part of computer architecture, and must be included in any serious study of the subject. But First, What is Security? In its broadest sense, security is about protecting assets. An asset is anything of value that is worth protecting, e.g. anything from the valuables in a bank vault to a secret message shared between friends to classified government information to objects of personal sentimental value. As long as an asset is valued, its owners should work to secure it. For an asset to be secure, security professionals generally think of the asset as maintaining three essential properties: • Confidentiality—Is the asset only accessible to those authorized to access it? In computer systems, maintaining confidentiality means controlling who can read some piece of information. -
(J. Bayko) Date: 12 Jun 92 18:49:18 GMT Newsgroups: Alt.Folklore.Computers,Comp.Arch Subject: Great Microprocessors of the Past and Present
From: [email protected] (J. Bayko) Date: 12 Jun 92 18:49:18 GMT Newsgroups: alt.folklore.computers,comp.arch Subject: Great Microprocessors of the Past and Present I had planned to submit an updated version of the Great Microprocessor list after I’d completed adding new processors, checked out little bits, and so on... That was going to take a while... But then I got to thinking of all the people stuck with the origional error-riddled version. All these poor people who’d kept it, or perhaps placed in in an FTP site, or even - using it for reference??! In good conscience, I decided I can’t leave that erratic old version lying out there, where people might think it’s accurate. So here is an interim release. There will be more to it later - the 320xx will be included eventually, for example. But at least this has been debugged greatly. Enjoy... John Bayko. — Great Microprocessors of the Past and Present (V 3.2.1) Section One: Before the Great Dark Cloud. ————————— Part I: The Intel 4004 (1972) The first single chip CPU was the Intel 4004, a 4-bit processor meant for a calculator. It processed data in 4 bits, but its instructions were 8 bits long. Internally, it featured four 12 bit(?) registers which acted as an internal evaluation stack. The Stack Pointer pointed to one of these registers, not a memory location (only CALL and RET instructions operated on the Stack Pointer). There were also sixteen 4-bit (or eight 8-bit) general purpose registers The 4004 had 46 instructions.
