RISC OS ndiyo inoshanda sisitimu yakatanga kugadzirwa naAcorn Computers Ltd muCambridge, England. Kutanga kuburitswa muna 1987, yakagadzirirwa kunyatso kumhanya pane iyo ARM chipset, iyo Acorn yakanga yakagadzirirwa panguva imwechete kuti ishandiswe mumutsetse wake mutsva weArchimedean makomputa ega.
Iyo RISC inoshanda sisitimu inotora zita rayo kubva kuRISC yakatsigirwa (yakadzikira mirayiridzo seta komputa) dhizaini.
Dzakawanda dzazvino shanduro dzakagadzikana mhanya pane ARMv3 / ARMv4 RISC PC, iyo ARMv5 Iyonix, pamwe nema processor, ARMv7, Cortex-A8, Cortex-A9 (senge iyo yakashandiswa muPandaBoard).
RISCOS Iyo yakajeka kwazvo system, kuisirwa kwakakwana kunotora isingasviki 4 Mb. Inogona kuiswa muFlash memory (padhuze neu-boot) yekutanga nekukurumidza.
Iyo sisitimu iri nyore nyore: mushandirapamwe multitasking, diki yekurangarira dziviriro.
Zvishoma nezve RISC OS
Iyo inoshanda sisitimu imwe chete mushandisi. Kunyangwe mazhinji emazuvano mazhinji-akapetwa ekudzivirira ekushandisa (PMT) uye multithreaded desktop desktop masisitimu, RISC OS inonamira neiyo CMT system.
Iyo kernel yeiyo inoshanda system inochengetwa muROM, kupa inokurumidza bhutsu nguva uye chengetedzo kubva kune inoshanda system huori.
Iyo system inopa nzira dzakawanda idzo programmer inogona kutora uye kugadzirisa mashandiro ayo. Izvi zvinorerutsa basa rekugadzirisa maitiro aro, kungave kuri muGUI kana zvakadzika.
File system
Iyo faira system eIyo yakatarisana nevhoriyamu: iyo yepamusoro nhanho yeiyo hierarchy vhoriyamu (disk, network share) yakakwenenzverwa neiyo faira system mhando.
Kuti uone iyo faira mhando, iyo inoshanda sisitimu inoshandisa metadata pachinzvimbo chefaira rekuwedzera.
Iyo colon inoshandiswa kupatsanura iyo faira sisitimu kubva kune yakasara yenzira; mudzi unomiririrwa ne $ () uye madhairekitori akapatsanurwa neyakagumira (.).
External file system extensions inoratidzwa neslash (example.txt inoshandurwa kuita example / txt).
Ichi inobvumira kujeka kubata kwemafaira uye akafanana mafaira, Ivo vanoita kunge madhairekitori ane zvimwe zvakakosha zvivakwa. Iwo mafaera ari mukati memufananidzo faira anoonekwa munzvimbo yepamusoro pazasi peiyo huru faira.
Faira mafomu
The operating system inoshandisa metadata kusiyanisa mafomati emafaira. Iyo MimeMap module inoratidzira mamwe akajairwa mafaira mhando kubva kune mamwe masisitimu kune faira mhando.
Desk
Iyo WIMP interface inoenderana ne stacking hwindo maneja uye inosanganisa matatu mbeva mabhatani (anonzi Sarudza, Menyu, uye Gadzirisa), mameseji-anotarisisa mamenyu, hwindo rekutonga kudzora (ndiko kuti, Push back), uye inesimba windows kutarisisa (hwindo rinogona kuve nekutarisisa kwekuisa pane chero chinzvimbo chiri mudura).
Iyo icon bar (Dock) ine mifananidzo inomiririra yakamisikidzwa dhisiki madhiraivha, RAM disks, inomhanya mashandisirwo, sisitimu zvinoshandiswa, uye madoko: asingashande mafaera, madhairekitori, kana kunyorera. Aya ma icon ane mamenu ezvinyorwa uye anotsigira kudhonza uye kudonhedza.
Applications
Iyo RISC inoshanda sisitimu inotakura ine akati wandei desktop desktop se pre-yakaiswa software.
Chekupedzisira, iyo RISC inoshanda sisitimu inouya neshanduro yeBBC BASIC, iyo inokutendera iwe kuti utange kuronga nemutauro uri nyore wekuwana.
Ungawana sei Risc OS?
Anenge makore ese kubva 1987, ingangoita imwe nyowani RISC OS inoenderana muchina waonekwa. Inonyanya kufarirwa nhasi iRaspberry Pi 3, BeagleBoard uye Pandora.
Vamwe vagadziri vanopa makomputa akazvipira, ayo anotendera mhanyisa muchina wekutenda, semuenzaniso, kushandiswa kweSATA yekubatanidza SSD (nekukurumidza kupfuura SD kadhi).
Pakupedzisira, eIyi sisitimu yakadaro yenzvimbo dzinogadzira kana mabasa ezuva nezuva haashande.
Nekudaro, inobatsira kwazvo kune avo vari kudzidza kuronga uye iyo sisitimu inoshanda zvakakwana sereferensi yekutarisa chimiro uye mashandiro ehurongwa hwekushandisa.
Kuti uwane iyi system pane yako Raspberry Pi, NOOBS inoita kuti zvive nyore kuisa uye kubhodhi iyo RISC inoshanda sisitimu.
