Compis
Compis (''COMPuter I Skolan'') was a computer system intended for the general educational system in Sweden and sold to Swedish schools beginning in 1984 through the distributor Esselte Studium, who also was responsible for the software packages. The computers were also used in Danish, Finnish and Norwegian schools under the name Scandis. History In 1980, the ABC 80 used in the schools was regarded as becoming obsolete, and the National Swedish Board for Technical Development (''Styrelsen för teknisk utveckling'') was tasked to find a replacement. In 1981, the procurement ''Tudis (Teknikupphandlingsprojekt Datorn i Skolan) '' was launched, and while the decision was controversial, Svenska Datorer AB was awarded the contract with development beginning in 1982. After Svenska Datorer went bankrupt, production was transferred to TeliDatorer/Telenova under Televerket (Sweden). The computer was distributed by Esselte and exclusively marketed towards, and sold to, Swedish, Norw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intel 80186
The Intel 80186, also known as the iAPX 186, or just 186, is a microprocessor and microcontroller introduced in 1982. It was based on the Intel 8086 and, like it, had a 16-bit external Bus (computing)#Address bus, data bus multiplexed with a 20-bit address bus. The 80188 variant, with an 8-bit external data bus was also available. Description The 80186 series was designed to reduce the number of integrated circuits required. It included features such as clock generator, interrupt controller, hardware timer, timers, wait state generator, direct memory access, DMA channels, and external chip select lines. It was used in numerous embedded systems, as microcontrollers with external memory. The initial clock rate of the 80186 was 6 MHz, but due to more hardware available for the microcode to use, especially for address calculation, many individual instructions completed in fewer clock cycles than on an 8086 at the same clock frequency. For instance, the common ''register+ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ABC 80
The ABC 80 (Advanced BASIC Computer 80) is a home computer engineered by the Swedish corporation Dataindustrier AB (DIAB) and manufactured by Luxor in Motala, Sweden in the late 1970s and early 1980s. It was introduced on the market in August 1978. The ABC 80 was based on an earlier modular computer system from the same company and built around a Z80 and of ROM containing a fast semi-compiling BASIC interpreter. It had of RAM as main memory and a dedicated (included) tape recorder for program and data storage, but could also be expanded to handle disk drives as well as many other peripherals. The ROM could be extended in increments of 1 or 4 KB in order to handle such so called "options". The monitor was a black and white TV set modified for the purpose, an obvious choice since Luxor also made TVs. The ABC 80 was used in schools and offices around Scandinavia and parts of Europe. It was also used for industrial automation, scientific measurement and control syste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Personal Computers
A personal computer, commonly referred to as PC or computer, is a computer designed for individual use. It is typically used for tasks such as Word processor, word processing, web browser, internet browsing, email, multimedia playback, and PC game, gaming. Personal computers are intended to be operated directly by an end user, rather than by a computer expert or technician. Unlike large, costly minicomputers and mainframes, time-sharing by many people at the same time is not used with personal computers. The term home computer has also been used, primarily in the late 1970s and 1980s. The advent of personal computers and the concurrent Digital Revolution have significantly affected the lives of people. Institutional or corporate computer owners in the 1960s had to write their own programs to do any useful work with computers. While personal computer users may develop their applications, usually these systems run commercial software, free-of-charge software ("freeware"), which i ...

Unisys ICON
The ICON (also the CEMCorp ICON, Burroughs ICON, and Unisys ICON, and nicknamed the bionic beaver) was a networked personal computer built specifically for use in schools, to fill a standard created by the Ontario Ministry of Education. It was based on the Intel 80186 CPU and ran an early version of QNX, a Unix-like operating system. The system was packaged as an all-in-one machine similar to the Commodore PET, and included a trackball for mouse-like control. Over time, a number of GUI-like systems appeared for the platform, based on the system's NAPLPS-based graphics system. The ICON was widely used in the mid to late 1980s, but disappeared after that time with the widespread introduction of PCs and Apple Macintoshes. History Development Origin In 1981, four years after the first microcomputers for mainstream consumers appeared, the Ontario Ministry of Education sensed that microcomputers could be an important component of education. In June the Minister of Educatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Education In Sweden
Education in Sweden is mandatory for children between ages 5/6 and 15/16 depending on when in the year they were born. The school year in Sweden runs from mid-late August to early/mid-June. The Christmas holiday from mid-December to early January divides the Swedish school year into two terms. Preschool is free for all families. The year children turn six they start the compulsory preschool class (), which acts as a transition phase between preschool and comprehensive schools. Children between ages 5/6 and 15/16 attend comprehensive school where a wide range of subjects are studied. All students study the same subjects, with exception for different language choices. The majority of schools are run municipally, but there are also privately owned schools, known as independent schools. Almost all students continue studying in three-year-long upper secondary schools where most students choose one out of 18 national programmes, some of which are vocational and some preparatory.

Megabyte
The megabyte is a multiple of the unit byte for digital information. Its recommended unit symbol is MB. The unit prefix ''mega'' is a multiplier of (106) in the International System of Units (SI). Therefore, one megabyte is one million bytes of information. This definition has been incorporated into the International System of Quantities. In the computer and information technology fields, other definitions have been used that arose for historical reasons of convenience. A common usage has been to designate one megabyte as (220 B), a quantity that conveniently expresses the binary architecture of digital computer memory. Standards bodies have deprecated this binary usage of the mega- prefix in favor of a new set of binary prefixes, by means of which the quantity 220 B is named mebibyte (symbol MiB). Definitions The unit megabyte is commonly used for 10002 (one million) bytes or 10242 bytes. The interpretation of using base 1024 originated as technical jargon for the byte m ...

Hard Disk
A hard disk drive (HDD), hard disk, hard drive, or fixed disk is an electro-mechanical data storage device that stores and retrieves digital data using magnetic storage with one or more rigid rapidly rotating hard disk drive platter, platters coated with magnetic material. The platters are paired with disk read-and-write head, magnetic heads, usually arranged on a moving actuator arm, which read and write data to the platter surfaces. Data is accessed in a random-access manner, meaning that individual Block (data storage), blocks of data can be stored and retrieved in any order. HDDs are a type of non-volatile storage, retaining stored data when powered off. Modern HDDs are typically in the form of a small disk enclosure, rectangular box. Hard disk drives were introduced by IBM in 1956, and were the dominant secondary storage device for History of general-purpose CPUs, general-purpose computers beginning in the early 1960s. HDDs maintained this position into the modern er ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Local Area Network
A local area network (LAN) is a computer network that interconnects computers within a limited area such as a residence, campus, or building, and has its network equipment and interconnects locally managed. LANs facilitate the distribution of data and sharing network devices, such as printers. The LAN contrasts the wide area network (WAN), which not only covers a larger geographic distance, but also generally involves Leased line, leased telecommunication circuits or Internet links. An even greater contrast is the Internet, which is a system of globally connected business and personal computers. Ethernet and Wi-Fi are the two most common technologies used for local area networks; historical network technologies include ARCNET, Token Ring, and LocalTalk. Cabling Most wired network infrastructures utilize Category 5 cable, Category 5 or Category 6 cable, Category 6 twisted pair cabling with RJ45 (telecommunications), RJ45 compatible terminations. This medium provides physical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Productivity Software
Productivity software (also called personal productivity software or office productivity software) is application software used for producing information (such as documents, presentations, worksheets, databases, charts, graphs, digital paintings, electronic music and digital video). Its names arose from it increasing productivity, especially of individual office workers, from typists to knowledge workers, although its scope is now wider than that. Office suites, which brought word processing, spreadsheet, and relational database programs to the desktop in the 1980s, are the core example of productivity software. They revolutionized the office with the magnitude of the productivity increase they brought as compared with the pre-1980s office environments of typewriters, paper filing, and handwritten lists and ledgers. In the United States, some 78% of "middle-skill" occupations (those that call for more than a high school diploma but less than a bachelor's degree) now require ...

Lotus Symphony For DOS
Lotus Symphony was an integrated software package for creating and editing text, spreadsheets, charts and other documents on the MS-DOS operating systems. It was released by Lotus Development as a follow-on to its popular spreadsheet program, Lotus 1-2-3, and was produced from 1984 to 1992. Lotus Jazz on the Apple Macintosh was a sibling product. IBM revived the name Lotus Symphony in 2007 for a new office suite based on OpenOffice.org, but the two programs are otherwise unrelated. History Lotus 1-2-3 had originally been billed as an integrated product with spreadsheet, database and graphing functions (hence the name "1-2-3"). Other products described as "integrated", such as Ashton-Tate's Framework and AppleWorks, from Apple Computer, normally included word processor functionality. Symphony was Lotus' response. Lotus advertised Symphony on television during the 1984 Summer Olympics. Overview Symphony for MS-DOS is a program that loads entirely into memory on startup, and ...
