Basic computer concepts

Origin[ edit ] John G. Kemeny was the math department chairman at Dartmouth College, and largely on his reputation as an innovator in math teaching, in they won an Alfred P. Kurtz had joined the department inand from the s they agreed on the need for programming literacy among students outside the traditional STEM fields.

It was as simple as that. These did not progress past a single freshman class. As Kurtz noted, Fortran had numerous oddly-formed commands, notably an "almost impossible-to-memorize convention for specifying a loop: Is it '1, 10, 2' or '1, 2, 10', and is the comma after the line number required or not?

Kurtz suggested that time sharing offered a solution; a single machine could divide up its processing time among many users, giving them the illusion of having a slow computer to themselves. Small programs would return results in a few seconds.

This led to increasing interest in a system using time-sharing and a new language specifically for use by non-STEM students. However, the syntax was changed wherever it could be improved. These changes made the language much less idiosyncratic while still having an overall structure and feel similar to the original FORTRAN.

About the author

Mary Kenneth Kellerone of the first Basic computer concepts in the U. Wanting use of the language to become widespread, its designers made the compiler available free of charge. In the s, software became a chargeable commodity; until then, it was provided without charge as a service with the very expensive computers, usually available only to lease.

They also made it available to high schools in the Hanover, New Hampshire area and put considerable effort into promoting the language. Spread on minicomputers[ edit ] "Train Basic every day! A version was a core part of the Pick operating system from onward, where a compiler renders it into bytecodeable to be interpreted by a virtual machine.

Ahl and published in a newsletter he compiled.

When management refused to support the concept, Ahl left DEC in to found the seminal computer magazine, Creative Computing. The book remained popular, and was re-published on several occasions. It had the advantage that it was fairly well known to the young designers and computer hobbyists who took an interest in microcomputers.

Despite Dijkstra 's famous judgement in"It is practically impossible to teach good programming to students that have had a prior exposure to BASIC: How to design and implement a stripped-down version of an interpreter for the BASIC language was covered in articles by Allison in the first three quarterly issues of the People's Computer Company newsletter published in and implementations with source code published in Dr.

Running Light Without Overbyte. The Apple II and TRS each had two versions of BASIC, a smaller introductory version introduced with the initial releases of the machines and a more advanced version developed as interest in the platforms increased. As new companies entered the field, additional versions were added that subtly changed the BASIC family.

Given BASIC's straightforward nature, it was a simple matter to type in the code from the magazine and execute the program. Different magazines were published featuring programs for specific computers, though some BASIC programs were considered universal and could be used in machines running any variant of BASIC sometimes with minor adaptations.

This book, and its sequels, provided hundreds of ready-to-go programs that could be easily converted to practically any BASIC-running platform. Turbo Pascal -publisher Borland published Turbo Basic 1.

These languages introduced many extensions to the original home-computer BASIC, such as improved string manipulation and graphics support, access to the file system and additional data types.

More important were the facilities for structured programmingincluding additional control structures and proper subroutines supporting local variables. However, by the latter half of the s, users were increasingly using pre-made applications written by others, rather than learning programming themselves, while professional programmers now had a wide range of more advanced languages available on small computers.

It included constructs from that language such as block-structured control statements, parameterized subroutines, and optional static typingas well as object-oriented constructs from other languages such as "With" and "For Each".

ER Model Basic Concepts The ER model defines the conceptual view of a database. It works around real-world entities and the associations among them.
Unit One - Basic Economic Concepts This book helps the student complete the transition from purely manipulative to rigorous mathematics. The clear exposition covers many topics that are assumed by later courses but are often not covered with any depth or organization:
Network Architectures: Networking In General What is a computer Network?
Chapter 1: Basic Computer Concepts Go to start of metadata Geographic Information Science is a field that requires basic computer literacy. The goal of these pages is to help students who are interested in GIS to be certain that they have mastered skills that are necessary to their success in future GIS courses and beyond.
There are class notes, numerous Supreme Court case summaries and information on how to write a research paper inside. Wants are different from needs as we will see below.

Chapter Two Basic Concepts. The good news is that HTML is written in plain text. That means you don’t need any fancy software programs to write your code. A Computer Science portal for geeks. It contains well written, well thought and well explained computer science and programming articles, quizzes and practice/competitive programming/company interview .

Basic Personal Computer Systems. A computer usually consists of input and output devices, storage devices, and a Central Processing Unit (CPU). This computer practice will focus only on the basic computer components needed for basic computer use or an average online course.
