Computer software

“ Not all hardware and software are compatible. In fact, hundreds of producers of computer equipment and computer programs are in the market, and there are few across-the-board standards. So it's important to get hardware and software that are compatible.
Software, or the computer programs themselves, are not like records that can be played on any record player. They have to be compatible with the hardware in terms of the programing language used, operating system, size, format, and other factors. ”

“ Many embedded computer applications require software that will continue to operate in the presence of faults.... The applications may require the monitoring of sensors, control of equipment displays or operator input processing. They must interface to special peripheral equipment.... Software must sometimes be able to respond at periodic (real time) intervals, to service interrupts within limited times, and to predict computation times.... In many applications..it is necessary to access, manipulate and display large quantities of data. ”

“ Given the exciting prospects for computer-based advanced automation in future missions, a program for more efficient, effective, and timely software development, management, and maintanance is mandatory. Principal software requirements are in the areas of programming languages, the software development environment, software validation, algorithm design, fault tolerance, and error recovery. Automatic programming should also be considered as a vehicle for improving the quality of software and the process of developing it. Data management. ”

“ Yet, as my little thought experiment above has hopefully made clear, the programmable web is anything but a pipe dream—it is today’s reality and tomorrow’s banality. No software developer will remain content to limit themselves only to things on the user’s own computer. And no web site developer will be content to limit their site only to users who act with it directly. ”

“ Software developed by a computer manufacturer usually takes advantage of the peculiarities of his own peripherals. If an outside device is purchased, the additional cost for programming during the lifetime of the system should be considered. If competent engineering effort is available, an interface compatible with the computer manufacturer's software may be built, with a possible saving in programming cost. ”

“ Using the tidy format makes this distinction clearer. One axiom about the structure of data and code holds that one should “write code for humans, write data for computers” [ [23] ] . When data can be easily imported and manipulated using familiar software (whether via a scripting language, a spreadsheet, or any other computer program that can import these common files) , data becomes easier to re-use. Furthermore, having the source code for the software doing the analysis available provides provenance for how the data is processed and analyzed. ”

“ Data bases, sometimes. “But word processors definitely take the cake.
“You’ve got to deal a lot with special features on printers, like boldfacing and underlining and whether the software will let them work right,” Park says. He suggests the obvious—that before buying new software, you find out how it will run with your printer and computer. Of course, as stated earlier, you’ll ideally select your hardware after you’ve chosen your general range of software. Park says most people don’t fully “realize the implications” of the software they’re ordering “because they haven’t thought of it yet.” ”

“ Don't underestimate the amount of time and effort it will require to collect data, make sure it's accurate, enter the data, and run the analyses.
It's important to consider how user-friendly the computer is, and how much the computer's software will do to guide you through the analysis.
A computer will do calculations very quickly, perhaps saving hours of laborious figuring. A computer will store information from one time period to the next, and recalculate alternatives quickly. By making the information available, it will help you identify strong and weak points in your operation. ”

“ We should pay attention to open source software because it shows us something about business methods in the digital world—indeed in the entire world of "information-based" products, which is coming to include biotechnology. The scale of your network matters. The larger the number of people who use your operating system, make programs for your type of computer, create new levels for your game, or use your device, the better off you are. A single fax machine is a paperweight. ”

“ When you were working on a machine like the TX-0, which came with almost no software, everyone would furiously write systems programs to make programming easier—Tools to Make Tools, kept in the drawer by the console for easy access by anyone using the machine. ”

“ Where do you find good software? Some farmers and ranchers write their own programs or pay a programmer to write a custom program. But most get existing programs either from State Extension sources or from commercial outlets.
Many operations farmers need to perform on a computer can be done by using generalized software packages readily available through commercial sources. ”

“ Programs are like people. “Mature” software is more reliable. It’s more like a tried-and-tested salesman or secretary, less risky, say, than a green employee hired off the street.
A complex creation like WordStar, with its thousands of lines of instructions for your computer, won’t ever be 100-percent glitchless. But it’s close. MicroPro, the company selling it, normally tests its programs well before unleashing them on the market, and WordStar has been around since the late 1970s, giving others the pleasure of suffering bugs before you have a chance. ”

“ Many computer experts strongly recommend against buying a computer first and then shopping for the software packages. So identify your needs and select the software packages or materials that will help you do what you want to with your computer. Then find the hardware to run the programs. ”

“ Files that use proprietary formats, such as word-processing programs, spreadsheets, database programs, etc. These files contain formatting (like italics, underlines, etc.) and perhaps graphics, and other goodies beyond the simple text.
2. "Application Programs". These are programs written in (the binary) machine language that your computer understands. They are "compiled" from text files of "source code" written in a programming language. Vendors almost never make their source code available—except for free software, which you may have to compile yourself. ”

“ However, significant advances in computer hardware and software have been made since that time. In particular, dramatic advances in large-scale integrated circuitry and microprocessor technology have permitted fabrication of mini-computers, micro-computers, and other special purpose devices, which are capable of duplicating many of the data-manipulative capabilities which were previously available only at centralized locations housing large scale general-purpose computers. ”

“ Because of the significance of software in the provision of enhanced services and sophisticated CPE, there is a need to address the allocation of its costs. Electronic equipment such as that used for computers and communications is becoming more and more software driven. ”

“ In this case, too, you can store material on your disk and later print it out.
3. Get copies of other programs that altruistic computer buffs have placed in the public domain; you do this after you log on the BBS.
MODEM7 is a good example of free software that fills a niche; experts say it’s better than some $150 products. Most free programs are losers for the typical business. ”

“ HARDWARE The term applied to the computer equipment—the processor unit, the storage devices, input devices, printers, etc. Hardware is differentiated from "software" and "firmware." INTERPRETER A computer program in the same general class as "assembler" and "compiler." All three INTERPRETER (cont'd) translate or change a programmer's source code into the object code that the computer uses. LANGUAGE In the computer field, the term generally means a programming language used by a programmer for writing a computer pro­gram. ”

“ Much like a mathematical or scientific formula, one can describe the function and design of encryption software by a prose explanation; however, for individuals fluent in a computer programming language, source code is the most efficient and precise means by which to communicate ideas about cryptography. [¶] ...The fact that a medium of expression has a functional capacity should not preclude constitutional protection. [¶] ... [¶] ... [C] omputer source code, though unintelligible to many, is the preferred method of communication among computer programmers. ”

“ Lotus 1-2-3, a combination of a spreadsheet, a graphics program, and several others, is far too complex for an 8-bit machine with 64K RAM. Many 16-bit programs require 192K or more just to load the program before you even put in your reports or spreadsheets.
3. You may want the most sophisticated software to thwart computer crooks. That could be particularly true in a large company where many people can poke through a computer’s memory either in person or via other machines connected by phone or other wires. ”

“ Even powerful vendors such as Microsoft rely on the support of third-party software developers whose tools, programs, and computer games make an underlying software platform such as Windows more attractive to the mainstream consumer. ”

“ Mail programs and text editors such as pico and pine promise much of the power of older programs such as emacs at a fraction of the complexity. Some software engineers are taking this even further, by creating graphical interfaces that will let somebody navigate the Internet just by clicking on the screen with a mouse or by calling up an easy text editor, sort of the way one can now navigate a Macintosh computer — or a commercial online service such as Prodigy. Then there are the Internet services themselves. ”

“ As an example systems software support is often entrusted to a single programmer who generates the version of the operating system in use, establishes password or other control lists and determines the logging and accounting features to be used. ”

“ For some projects there is no host computer and implementation is directly on the target machine with minimal support facilities.
2.A.6 TESTING:
(a) Syntactic and static semantic errors are resolved simply at source code level by the compiler;
(b) The next stage of module testing may be done in the host if an instruction level simulator for the target exists; this is more likely if some simplified environment simulator is available on the host to provide test data input;
(c) The real testing takes place in the "software test lab." ”

“ Definitions.—In this subpart: `` (1) Computer.—The term `computer' includes any hardware, software, or other technology attached or connected to, installed in, or otherwise used in connection with a computer. `` (2) Access to internet.—A computer shall be considered to have access to the Internet if such computer is equipped with a modem or is connected to a computer network that has access to the Internet. ”

“ Computing is ubiquitous in every domain of scientific research. Software is the means by which scientists harness the power of computers, and much scientific computing relies on software conceived and developed by other practicing researchers. The task of creating scientific software, however, does not end with the publication of computed results. Making the developed software available for inspection and use by other scientists is essential to reproducibility, peer-review, and the ability to build upon others' work [1] , [2] . ”

“ Planning and Procuring a Data-Acquisition System Today
It is no longer necessary to develop one's own system. Times have changed greatly. Many systems now exist which work well and are worth copying. Manufacturers and suppliers are prepared to deliver entire systems assembled and ready to operate, complete with all the necessary system software and varying amounts of utility software. ”

“ At least by this point, if not sooner, usability should become a priority. Unfortunately, efforts in scientific software development are constrained by limited funding, time, and rapid turnover of group members. As a result, scientific software is often poorly documented, non-intuitive, non-robust with regards to input data and parameters, and hard to install. For many use cases, there is a plethora of tools that appear very similar and make it difficult for the user to select the one that best fits their needs. ”

“ Nevertheless, good usability is imperative for achieving wide acceptance of a software tool in the community. In many cases, academic software starts out as a prototype that solves one specific task and is not geared for a larger user group. As soon as the developer realizes that the complexity of the problems solved by the software could make it widely applicable, the software will grow to meet the new demands. ”

“ Consequently, academic software is typically released as a prototype. We acknowledge that such a tool cannot adhere to and should not be judged by the standards that we take for granted for production grade software. However, widespread use of a tool is typically in the interest of a researcher. To this end, we propose ten simple rules that, in our experience, have a considerable impact on improving usability of scientific software. ”
