The most basic solution was a pure software system supplied on a ROM cartridge that drew a low resolution approximation of the mode 7 display in a graphics mode.

Although cheap and effective in enabling use of some software that only used official ROM entry points for text output, this solution proved very slow because the Electron had to be placed into an 80-byte-pitch display to be able to get anywhere near to reproducing mode 7 and the CPU spent a lot of time drawing approximations of mode 7 characters and graphics that in a hardware solution would be achieved without any CPU processing.

A software ROM would put the machine into an ordinary 40-byte-pitch display.

A software ROM worked around this by duplicating the data intended for a mode 7 display in memory.

Although this produced a mode 7 that barely impacted upon CPU performance and gave the same visual quality as the BBC Micro, it remained compatible only with software that used the ROM routines for outputting text and graphics and still used 10 kB of memory for the display.

BIOS software is stored on a non-volatile ROM chip on the motherboard.

Later ROM revisions fixed assorted problems, including a software bug that made the Save And Replace command unusable.

Also, a software solution, which resided in the drive controller's ROM, could prevent the re-reads from occurring, though this could cause problems when genuine errors did occur.

However, a hardware bug with this chip prevented the initial design from working as anticipated, and the ROM code was hastily rewritten to handle the entire operation in software.

It could be expanded with RAM ( memory ) and ROM ( software ) modules, as well as peripherals like bar code readers, microcassette and floppy disk drives, paper-roll thermal printers, and miscellaneous communication interfaces ( RS-232, HP-IL, HP-IB ).

This included the use of ROM for library software that could be run much faster than the same code in the normal core memory, due to the latter ’ s need to be written immediately after being read.

In order to keep the cost of software down, it was decided that the software media would be 3. 5 ” floppy discs rather than ROM cartridges used universally by consoles up to that time.

This expectation was, in reality, never quite met: Motorola's only released example of a ROM'd software module was the MC6839 floating-point ROM.

The ROM and Mac OS operating system released with the new Power Mac machines included an Mac 68K emulator to enable programs written for Motorola 68k series CPUs, including nearly all prior Mac software, to run without changes.

For software distributed on ROM cartridges, subroutines were included which attempted to write over the program code.

If the software was on ROM, nothing would happen, but if the software had been moved to RAM, the software would be disabled.

These changes resulted in minor incompatibility problems with software that accessed ROM routines at certain addresses.

These kits included IR capability, a new plastic memory door to accommodate the IR diodes, a memory card with 1 MB, the new ROM for Palm OS 2. 0, and a CD ROM with updated desktop software.

The Stinger-RMP is so-called because of its ability to load a new set of software via ROM chip inserted in the grip at the depot.

* " Atlas " was the former name for ASP. NET AJAX, Microsoft software, a set of ASP. NET extensions providing Ajax functionality

It was designed to avoid some of the perceived problems with FORTRAN for backward compatibility with historic Buran ( spacecraft ) ALGOL software.

Although early Commodore advertisements attempted to cast the computer as an all-purpose business machine, the Amiga was most commercially successful as a home computer, with a wide range of games and creative software.

The 68000 has a 16-bit external data bus so must transfer 32 bits of data in two consecutive steps, a technique called multiplexing: all this is transparent to the software, which was 32-bit from the beginning.

Although the hardware is limited to four separate sound channels, software such as OctaMED uses software mixing to allow eight or more virtual channels, and it was possible for software to mix two hardware channels to achieve a single 14-bit resolution channel by playing with the volumes of the channels in such a way that one of the source channels contributes the most significant bits and the other the least.

A retargetable sound API called AHI was developed allowing these cards to be used transparently by the OS and software.

Whilst it may not have been as popular as the Spectrum, Commodore 64 or Amstrad CPC, it did sell in sufficient numbers to ensure that new software was being produced right up until the early 1990s.

This was quickly remedied by First Byte Computers who developed an interface and software which allowed a " switched " joystick to be used with the majority of software titles.

The first used the same graphics processor as the BBC Micro in mode 7 — the SAA5050 — but used software to ensure that it was fed with the correct graphics data.

Tridgell was a major developer of the Samba software, analysing the Server Message Block protocol used for workgroup and network file sharing by Microsoft Windows products.

* The program was stored as a linked list of lines ; a or took O ( n ) ( linear ) time, and although Applesoft programs were not very long compared to today's software, on a 1 MHz 6502 this could be a significant bottleneck.

AIX was the first operating system to utilize journaling file systems, and IBM has continuously enhanced the software with features like processor, disk and network virtualization, dynamic hardware resource allocation ( including fractional processor units ), and reliability engineering ported from its mainframe designs.

One of the more popular desktop applications was the PageMaker desktop publishing software.

Although the Aster was a clone of the TRS-80 model I it was in fact more compatible with the TRS-80 model III, and ran all the software of these systems including games.

It also had a built in speaker which was compatible with such games software.

A third mode was entered with a special boot floppy which turned the Aster into a Videotex terminal with a 40x25 display and a Videotex character set, The software used the built in RS232 interface of the Aster to control a modem through which it could contact a Prestel service provider.

Another important demand was that the computers could be used in a network ( Aster developed special software and hardware for that ).

Later however the Government turned around and gave 50 % of the order to Philips and their P2000 homecomputer even though the P2000 did not meet all the technical demands, was made in Austria and did not have network hard nor software.

Today, most BBS software that is still actively supported, such as Worldgroup, Wildcat!

There are many successful companies today that sell only software products, though there are still many common software licensing problems due to the complexity of designs and poor documentation, leading to patent trolls.

Although most manufacturers of hard disk drives and flash-memory disk devices define 1 gigabyte as, software like Microsoft Windows reports size in gigabytes by dividing the total capacity in bytes by, while still reporting the result with the symbol " GB ".

When floating point operations needed to be performed they were still performed, but not in hardware ; instead the operations were usually facilitated by transparent software emulation.

Mattel said that the Keyboard Component was a real product still being test-marketed and even released a small number of Keyboard Components to a handful of retail stores, along with a handful of software titles in order to support this claim.

The Amstrad PCW's bundled word processing software, LocoScript, used the term " in limbo " to refer to files which had been deleted but which could still be restored, a concept similar to that later implemented by the Trash in the Apple Macintosh and the Recycle Bin in Microsoft Windows 95.

Availability of WYSIWYG (" what you see is what you get ") publishing software supplanted much use of these languages among casual users, though serious publishing work still uses markup to specify the non-visual structure of texts, and WYSIWYG editors now usually save documents in a markup-language-based format.

The current definition of software engineering is still being debated by practitioners today as they struggle to come up with ways to produce software that is " cheaper, better, faster ".
