'THE BOOK' is back!


We're really excited about the release this spring of the 14th edition of Computers: Systems, Terms and Acronyms. It's the latest edition of the book thousands have relied on since 1989 to explain technology in plain English - with new information, new terms, and even a new size! The 14th edition includes 17 chapters of broad coverage of IT and over 3,000 definitions of the most common technical skills and products. It's a stand-alone tool but works best as a companion to TechRef, our 24/7 online database which has more than 14,000 entries!

Find out about our pre-release special. Details follow in the following article: Go to "THE BOOK" is Back!

DEVELOPMENT METHODOLOGIES and TECHNIQUES

Discussions of software development usually concentrate on languages and tools, as these are visible and definitive. We know the names of languages, and know that different languages are used by different programmers for different assignments. Development tools, which are used for design and testing in addition to writing programs, also have names and specific functionality which usually follows a defined methodology or technique.

Almost as soon as people started to use computers to solve business problems, the need for rules and standards to govern the development process appeared. The first methodologies were defined in the early 1970s, and concentrated on stating rules for developing software that would make it easier for someone else to understand and maintain (make changes). These methodologies concentrated on the programming and testing phases. Standardizing development is still a major goal, however, the current methodologies are equally concerned with the quality of the product being developed and SQA (Software Quality Assurance) is the basis for many of today’s methodologies.

Today’s SQA produces methodologies that define standards for development and include formal monitoring to make sure that the standards are followed. Because the standards must be set in the beginning of the development life cycle, and testing is the most common QA activity, these methodologies cover the entire life cycle. Techniques used in various methodologies include inspections, algorithm analysis, decision-table analysis, and Petri-net modeling, all of which can be used in design.

An inspection is an example of a non-testing QA technique, and is based on a technique introduced in the ‘70s - the programming walkthrough. Every time a program was written, a walkthrough would be scheduled. The program code would be reviewed by a team of developers, and potential problems would be discovered before the programs were actually tested. Walkthroughs are the basis of inspections which is a technique used in the XP (eXtreme Programming) methodology. An inspection is a critical examination of software development by a formal, group review of documents created during the development process. While most often it is program code that is inspected, program specifications, data diagrams, test plans and test data, and other documents can also be inspected. Extreme programming operates on the principle of not allowing errors into systems and uses inspections to review analysis and design documents before the code is even written. This is to keep errors out of the code and not let them get to the programming and testing phases The objective is to find errors quickly, and techniques that work in the analysis and design phases are becoming more popular. They supplement the many testing techniques that are a necessary part of any quality assurance methodology.

Several QA methodologies are used, the most popular being Six Sigma, TQM (Total Quality Management), and CMM (Capability Maturity Model). TQM appeared first, and describes a methodology of quality control for software development. It works with ongoing refinements of the software product and continual feedback thus improving software in small increments. It was developed by IBM in the mid-1970s, and is part of ISO 9000 compliance. CMM was introduced by SEI (Software Engineering Institute) in the mid-1980s and defines five levels of effectiveness: initial (ad hoc and chaotic), repeatable, defined, managed, and optimizing (piloting new development ideas and technologies.) Six Sigma is a term used by statisticians and engineers to describe a state of nearly zero defects. It's used in IT to define a methodology for quality control during software development and focuses on critical core processes to understand customer requirements and align work processes. It uses analytical tools to improve these processes and was introduced in 1987.

As writing and testing programs becomes easier and with languages and tools that can automate much of the coding and testing, analysis and design skills are more visible. These are the development phases that actually create the program solutions, and methodologies and techniques concentrate more and more on these activities.

'THE BOOK' is Back!


Stop your frustration! IT professionals seem to speak a different language, and it’s uncomfortable when you don’t understand what they’re saying. Your job becomes harder than it has to be, and it’s no fun spending hours researching technical terms when everything you find is written for someone with a technical background.

SemCo’s reference tools put plain English explanations in your hands. Complementary products – Computers: Systems, Terms and Acronyms (CSTA), a hard-copy bound book, and TechRef, a 24/7 online database - are designed specifically for people without a technical background and can be purchased together or separately.

Which resource do you need?
The CSTA book contains the broad coverage of Information Technology and over 3,000 definitions of the most common technical skills and products. This is the easiest and quickest way to look up a new technical term or research overall concepts and systems. If you’re new to working with technology, prefer to hold a book in your hand, or work with a fairly stable technical environment, the book will provide the information you need. If, however, you need the latest and most thorough information, and work with all kinds of diverse technologies, TechRef provides additional material. The online database contains 11,000 additional entries and uses the ability of an online system to search for information, build lists of data, and provide new information 24/7. In fact, because TechRef is updated when products and technologies are announced, it covers not just today’s technology, it even covers what’s going to happen. Professionals such as technical recruiters, technical salespeople, and account managers, who interface with IT every day use TechRef to keep up with the incredibly dynamic IT field.

Perhaps, like many people, you want to have the book for quick and easy access, and the database for immediate updates and uncommon terms and information. This combination offering is a popular option.

COMPUTERS: SYSTEMS, TERMS AND ACRONMYS
Part One consists of the narrative descriptions of computer systems. This edition includes 17 chapters that cover Information Technology:


Introduction:
  • IT Overview
  • IT Jobs and Professionals

    Applications:
  • Corporate Applications
  • eApplications
  • Artificial Intelligence

    Platforms:
  • Computers
  • Operating Systems
  • Security
  • Storage Management

    Development:
  • Development Life Cycle
  • Languages and Tools
  • Software Engineering

    Data:
  • Files and Databases
  • Data Management Systems

    Online:
  • Communications
  • Middleware and Servers
  • Networking


  • New material in these chapters includes the effect of the Internet, the emerging influence of wireless and embedded technology, the growth of knowledge management and business intelligence systems, and new storage management technologies. There is extended coverage of security systems, the use of artificial intelligence, and Web services and portals. This is where you start for a broad understanding of any IT system.

    Part Two remains the glossary for definitions of technical terms and acronyms. This glossary has been streamlined and now contains over 3,000 generic definitions of standard terms and technologies. These are the words IT professionals use to describe the technologies they work with and the systems they create. In addition, it contains definitions of the most common products and tools used in IT. These definitions include the name and URL of the vendor. Part Two is where non-technical people go to understand specific IT buzz words.

    TECHREF
    TechRef, the only online IT database designed specifically for the non-technical professional, contains everything included in the book and much more. All 17 chapters are available as PDF files and there are over 14,000 entries. TechRef is where you will find definitions and information on leading-edge and uncommon products as well as older technologies and products – information which will not be found in the new book. Finally, TechRef contains information on thousands of vendors with a brief description of the vendor, a link to its corporate Website, and a list of its products.

    TechRef contains over 150 technical categories so lists of products can be viewed according to function making it easy to answer the question “What else is similar?” Search functions allow users to find products even if they don’t know, or perhaps can’t spell, a product name. Search options offer you the ability to look for a specific product, or a list of products by various criteria including vendor, type, keyword, and advanced options such as product type and vendor. The distinct layers of information within TechRef (papers, categories, terms and vendors) allow the user to research and learn by "drilling down" from concepts to details or "powering up" from specifics to overviews.

    TechRef is available 24/7, and is updated daily – whenever new products are released, revised, renamed, and whenever new technology appears. Access is provided through annual subscriptions.

    Short Information Appliance Vocabulary


    An information appliance is a specialized computer that is built with embedded systems, which can be any of these: operating systems, DBMSs, application systems, or Web browsers. An information appliance can be anything. For example, the Screenfridge is an information appliance that is a Web-connected refrigerator. It has a PC screen in the door and a built-in modem and food can be ordered over the Internet. It also includes speakers, a microphone and video camera so family members can leave video messages. Information appliances are also called Internet appliances.

    e-book reader Information appliance. An ebook is a device that can download information in text/graphics format from the Internet, or access text on CDs or DVDs and present it on a display in a readable format. Typically, an eBook reader weighs less than three or four pounds and can store from four thousand to over half a million pages of text and graphics. The device is called an ebook reader, and the electronic versions of the text is the ebook. ebooks are usually in PDF format.

    kiosk A kiosk is really a Web tablet, usually standing vertically, that is set up in public places for things such as making restaurant reservations, getting directions, etc. They have touch screens and are in constant use so they are more rugged than most other computers or appliances.

    photo-frame A photo-frame is a device that looks like a photo frame and connects to phone lines. Photos (or anything desired) can be transmitted to the frame. Single photos can be displayed, or can be paged through. Also called digital frames.

    Answers to TechCheck


    1. Computer users blink an average of 7 times per minute. The average person blinks 22 times per minute.

    2. Reverse engineering is going backwards in the development life cycle, which follows the sequence: analysis, design, programming, testing. Especially with legacy systems, often the only documentation that has survived is the program source code. This makes it difficult to incorporate changes that should be initiated on the design level. Creating design documents from program code reverses the sequence of the life cycle by going from programming to design – thus reverse engineering.

    Round-trip engineering completes a circle. It works from program code to create design documents (reverse engineering), changes the design documents as required, and then generates new program code from the new designs – ending up where the activity began, with program code – thus round-trip engineering.

    3. This one has several answers!

    a. ICE - Information Communication Entertainment. This is when the acronym is part of iCEBox, an information appliance (see Short Information Appliance Vocabulary).

    b. ICE - In-Circuit Emulator. A tool used to debug embedded systems.

    c. ICE - Information and Content Exchange. This is a proposed standard to simplify the transmission of data between businesses over the Internet.


    4. This one’s an opinion question. I vote for churn (leaving a Website). I just can’t see where the word came from. Stickiness (design qualities that keep a visitor on a Website), however, actually makes sense.

    5. No matter how you look at it, it’s got to be (b) Mouse. While a first thought might be that a mouse is an animal while the others are insects, that’s not it. It’s also not that mice are kind of cute while the others are not. And, it’s not that mice aren’t venomous. Actually it’s just that a mouse is a piece of hardware, and all the rest are software.
    a. ANT is a development tool used for iterative development. It’s often called a build tool, which is software that assembles all the parts of an application. Ant is open source software and frequently used to "build" Java applications.

    c. A spider is a program that prowls the Internet, attempting to locate new, publicly accessible resources such as Web documents and files available in public archives. Also called wanderers or robots (bots), spiders store the information they find in a database, which Internet users can search by using an Internet-accessible search engine. Used to, e.g., search the Web for email addresses of doctors.

    d. Scorpion is systems software that works with NetWare systems and converts Traditional volumes to NSS volumes and NSS volumes to Traditional volumes.

    e. WASP is application development software used to build, deploy, and manage Web services. Based on Web Services standards: XML, SOAP, WSDL and UDDI. It works with Java and C++ and interfaces with .NET and J2EE.
