MSX-DOS
MSX-DOS is a discontinued disk operating system developed by Microsoft's Japan subsidiary for the 8-bit home computer standard MSX, and is a cross between MS-DOS v1.25 and CP/M-80 v2.2. MSX-DOS MSX-DOS and the extended BASIC with 3½-inch floppy disk support were simultaneously developed by Microsoft and ASCII Corporation as a software and hardware standard for the MSX home computer standard, to add disk capabilities to BASIC and to give the system a cheaper software medium than Memory Cartridges, and a more powerful storage system than cassette tape. The standard BIOS of an unexpanded MSX computer had no built-in disk support, but provided hooks for a disk extension, so the additional floppy disk expansion system came with its own BIOS extension ROM (built-in on the disk controller) called the BDOS. This BIOS not only added floppy disk support commands to MSX BASIC, but also a booting system, with which it was possible to boot a real disk operating system. MSX-DOS w ...

Philips NMS 8245
The Philips NMS 8245 is a personal computer released by Philips in 1987 as part of its MSX2 line of computers. The NMS 8245, being compatible with the MSX2 standard, benefitted from the improvements introduced over the original MSX system, which include better graphical performance, more memory, and support for hardware sprites and smooth scrolling, which made it a popular choice for video games. However, like other MSX systems, it faced competition from other home computers such as the Commodore 64, Amiga, and Atari ST. Description The NMS (New Media Systems) branding reflected Philips' efforts to market the machine with a focus on multimedia, contrary to the previous VG (Video Game) series machines . This was reinforced by offering the machine with three software discs: ''MSX-DOS 1'', ''Ease'' (a multilingual office suite) and ''Designer Plus'' (a drawing program). The Philips NMS 8245 features a black and silver plastic casing with an integrated keyboard, similar to the VG- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MSX2 Microcomputer
MSX is a standardized home computer architecture, announced by ASCII Corporation on June 16, 1983. It was initially conceived by Microsoft as a product for the Eastern sector, and jointly marketed by Kazuhiko Nishi, the director at ASCII Corporation. Microsoft and Nishi conceived the project as an attempt to create unified standards among various home computing system manufacturers of the period, in the same fashion as the VHS standard for home video tape machines. The first MSX computer sold to the public was a Mitsubishi ML-8000, released on October 21, 1983, thus marking its official release date. MSX systems were popular in Japan and several other countries. There are differing accounts of MSX sales. One source claims 9 million MSX units were sold worldwide, including in Japan alone, whereas ASCII Corporation founder Kazuhiko Nishi claims that 3 million were sold in Japan, and 1 million overseas. Despite Microsoft's involvement, few MSX-based machines were released in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Operating System
An operating system (OS) is system software that manages computer hardware and software resources, and provides common daemon (computing), services for computer programs. Time-sharing operating systems scheduler (computing), schedule tasks for efficient use of the system and may also include accounting software for cost allocation of Scheduling (computing), processor time, mass storage, peripherals, and other resources. For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware, although the application code is usually executed directly by the hardware and frequently makes system calls to an OS function or is interrupted by it. Operating systems are found on many devices that contain a computerfrom cellular phones and video game consoles to web servers and supercomputers. , Android (operating system), Android is the most popular operating system with a 46% market share, followed ...

Video Random-access Memory
Video random-access memory (VRAM) is dedicated computer memory used to store the pixels and other graphics data as a framebuffer to be rendered on a computer monitor. It often uses a different technology than other computer memory, in order to be read quickly for display on a screen. Relation to GPUs Many modern GPUs rely on VRAM. In contrast, a GPU that does ''not'' use VRAM, and relies instead on system RAM, is said to have a unified memory architecture, or shared graphics memory. System RAM and VRAM have been segregated due to the bandwidth requirements of GPUs, and to achieve lower latency, since VRAM is physically closer to the GPU die. Modern VRAM is typically found in a Ball grid array, BGA package soldered onto a graphics card. The VRAM is cooled along with the GPU by the GPU heatsink. Technologies * Dual-ported video RAM, used in the 1990s and at the time often called "VRAM" * SGRAM * GDDR SDRAM * High Bandwidth Memory (HBM) See also * Graphics processing unit * ...

AZERTY
AZERTY ( ) is a specific layout for the characters of the Latin alphabet on typewriter keys and computer keyboards. The layout takes its name from the first six letters to appear on the first row of alphabetical keys; that is, ( ). Like other European keyboard layouts, it is modelled on the English-language QWERTY layout. It is used in France and Belgium, though both countries have their own national variation on the layout. The competing layouts devised for French (e.g. the 1907 ZHJAY layout, Claude Marsan's 1976 layout, the 2002 Dvorak-fr, and the 2005 BÉPO layout) have obtained only limited recognition, although the latter has been included in the 2019 French keyboard layout standard. History The AZERTY layout appeared in France in the last decade of the 19th century as a variation on American QWERTY typewriters. Its exact origin is unknown. It was more successful than its contemporaries (e.g. the French ZHJAYS layout created by Albert Navarre in the early 20th cen ...

QWERTZ
The QWERTZ ( ) QWERTZU ( ), or QWERTZUIOP keyboard is a typewriter and keyboard layout widely used in Central and Southeast Europe. The name comes from the first six letters at the top left of the keyboard: ( ). Overview The main difference between QWERTZ and QWERTY is that the positions of the and keys are switched (hence the nickname "kezboard"). This change possibly was made for three major reasons: * is a much more common letter than in German; the latter appears only in loanwords (mainly from Ancient Greek) and in proper names such as Meyer (alongside Meier and various other variants). * and often appear next to each other in the German orthography, and typewriter jamming would be reduced by placing the two keys so they could be typed with separate hands. * and are also next to each other. , meaning "to" in German, and also a very common prefix can also be written very easily. Similar to many other non-English keyboards: * Part of the keyboard is adapted to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
QWERTY
QWERTY ( ) is a keyboard layout for Latin-script alphabets. The name comes from the order of the first six Computer keyboard keys#Types, keys on the top letter row of the keyboard: . The QWERTY design is based on a layout included in the Sholes and Glidden typewriter sold via E. Remington and Sons from 1874. QWERTY became popular with the success of the Remington No. 2 of 1878 and remains in ubiquitous use. History The QWERTY layout was devised and created in the early 1870s by Christopher Latham Sholes, a newspaper editor and printer who lived in Kenosha, Wisconsin. In October 1867, Sholes filed a patent application for his early writing machine he developed with the assistance of his friends Carlos Glidden and Samuel W. Soule, Samuel W. Soulé. The first model constructed by Sholes used a piano-like keyboard with two rows of characters arranged alphabetically as shown below: - 3 5 7 9 N O P Q R S T U V W X Y Z 2 4 6 8 .

Floppy Disk Drive
A floppy disk or floppy diskette (casually referred to as a floppy, a diskette, or a disk) is a type of disk storage composed of a thin and flexible disk of a magnetic storage medium in a square or nearly square plastic enclosure lined with a fabric that removes dust particles from the spinning disk. The three most popular (and commercially available) floppy disks are the 8-inch, 5¼-inch, and 3½-inch floppy disks. Floppy disks store digital data which can be read and written when the disk is inserted into a floppy disk drive (FDD) connected to or inside a computer or other device. The first floppy disks, invented and made by IBM in 1971, had a disk diameter of . Subsequently, the 5¼-inch (133.35 mm) and then the 3½-inch (88.9 mm) became a ubiquitous form of data storage and transfer into the first years of the 21st century. 3½-inch floppy disks can still be used with an external USB floppy disk drive. USB drives for 5¼-inch, 8-inch, and Floppy disk variants, other-size fl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MSX BASIC
MSX BASIC is a dialect of the BASIC programming language. It is an extended version of Microsoft's MBASIC Version 4.5, adding support for graphic, music, and various peripherals attached to MSX microcomputers. Generally, MSX BASIC is designed to follow GW-BASIC, released the same year for IBM PCs and clones. During the creation of MSX BASIC, effort was made to make the system flexible and expandable. Distribution MSX BASIC came bundled in the Read-only memory, ROM of all MSX computers. At system start-up MSX BASIC is invoked, causing its command prompt to be displayed, unless other software placed in Read-only memory, ROM takes control (which is the typical case of ROM cartridge, game cartridges and disk interfaces, the latter causing the MSX-DOS prompt to be shown if there is a disk present which contains the DOS system files). When MSX BASIC is invoked, the ROM code for BIOS and the BASIC interpreter itself are visible on the lower 32K of the Zilog Z80, Z80 addressing space. ...

Random-access Memory
Random-access memory (RAM; ) is a form of Computer memory, electronic computer memory that can be read and changed in any order, typically used to store working Data (computing), data and machine code. A random-access memory device allows data items to be read (computer), read or written in almost the same amount of time irrespective of the physical location of data inside the memory, in contrast with other direct-access data storage media (such as hard disks and Magnetic tape data storage, magnetic tape), where the time required to read and write data items varies significantly depending on their physical locations on the recording medium, due to mechanical limitations such as media rotation speeds and arm movement. In today's technology, random-access memory takes the form of integrated circuit (IC) chips with MOSFET, MOS (metal–oxide–semiconductor) Memory cell (computing), memory cells. RAM is normally associated with Volatile memory, volatile types of memory where s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
