ZIP Compression Algorithm ke sesebelisoa sa bohlokoa lefats'eng la likhomphutha se u lumellang ho fokotsa boholo ba lifaele le li-directory ho boloka sebaka sa polokelo le ho tsamaisa phetiso ea tsona ka mekhoa ea elektroniki. E thehiloe ke Phil Katz ka 1989, algorithm ena e sebelisa motsoako oa mekhoa ea compression le encryption ho fihlela katleho e phahameng phokotsong ea boholo ba faele. Sehloohong sena, re tla hlahloba ka botebo hore na algorithm ena e sebetsa joang, litšobotsi tsa eona tsa mantlha le ts'ebeliso ea eona lefapheng la mahlale.

1. Kenyelletso ho ZIP Compression Algorithm

Algorithm ea compression ea ZIP e sebelisoa haholo ho fokotsa boholo ba faele le ho etsa hore ho be bonolo ho e fetisetsa kapa ho e boloka. Algorithm ena e sebelisa motsoako oa mekhoa ea compression le encryption ho fihlela sekhahla se phahameng sa khatello ntle le ho lahleheloa ke botšepehi ba data.

Khatello ea ZIP e sebetsa ka ho arola faele ka li-block tse nyane le ho sebelisa li-algorithms tsa khatello e sa lahleheng ho block ka 'ngoe. Li-algorithms tsena li batla lits'oants'o tsa data mme li li tlose ho fokotsa boholo ba faele e hlahisoang. Ho feta moo, buka e hlalosang mantsoe e sebelisoa ho boloka tlhahisoleseding e mabapi le ho pheta-pheta mohlala ho data, ho lumella ho hatella hantle.

Ho fokotsa khatello ea maikutlo ho tsoa faeleng ZIP ke ts'ebetso e khutlisetsang morao, moo data ea mantlha e khutlisoang ho tsoa faeleng e hatelitsoeng. Ts'ebetso ena e kenyelletsa ho khutlisetsa morao li-algorithms tsa compression tse sebelisoang nakong ea khatello, ho sebelisa bukana e bolokiloeng ho khutlisa mekhoa ea data ea mantlha. Ka hona, ho bohlokoa ho hlokomela hore compression ea ZIP ke khatello e sa lahleheng, ho bolelang hore ha ho na tlhahisoleseling e lahlehileng nakong ea ts'ebetso ea khatello le decompression.

2. Kamoo Algorithm ea ZIP Compression e sebetsang kateng

Algorithm ea compression ea ZIP e sebelisoa haholo ho fokotsa boholo ba faele le ho nolofatsa lipalangoang le polokelo. Ka tlase, ts'ebetso ea algorithm ena e tla hlalosoa ka botlalo ka mehato e meraro ea bohlokoa.

1. Khatello ea faele: Mohato oa pele oa ho sebelisa algorithm ea compression ea ZIP ke ho khetha lifaele tseo u batlang ho li hatella. Tsena e ka ba litokomane tsa mongolo, litšoantšo, livideo kapa mefuta e meng ea lifaele. Ha e se e khethiloe, software e lumellanang le ZIP e sebelisoa ho hatella lifaele. Nakong ea ts'ebetso ena, algorithm e batla mekhoa e pheta-phetoang ea data mme e e nkela sebaka ka litšupiso tse khutšoane, e leng se hlahisang faele e nyane e hatelitsoeng.

2. Sebopeho sa faele ea ZIP: Hang ha lifaele li se li hatelitsoe, faele ea ZIP e nang le sebopeho se itseng e tla etsoa. Faele ena ea zip e na le letoto la likenyelletso, moo kenyelletso ka 'ngoe e emelang faele e le 'ngoe ka har'a faele ea ZIP. Ho feta moo, faele ea ZIP e na le hlooho e bolokang tlhahisoleseling mabapi le likenyo, joalo ka lebitso la faele, tsela, le boholo bo hatelletsoeng le bo sa hatelloang.

3. Faele decompression: Mohato oa ho qetela ke decompression ea difaele. Ho nyenyefatsa faele ea ZIP, ho sebelisoa software e tsamaellanang e hlophisang lifaele tsa mantlha ho tsoa mengolong le tlhaiso-leseling e bolokiloeng hloohong ea faele ea ZIP. Nakong ea ts'ebetso ena, algorithm e khutlisetsa morao ts'ebetso e entsoeng nakong ea khatello, e khutlisetsa data ka mokhoa oa eona oa pele. Hang ha lifaele li se li butsoe, li ka sebelisoa ka mokhoa o tloaelehileng.

Ka kakaretso, algorithm ea compression ea ZIP e sebetsa ka ho khetha le ho hatella lifaele, ho theha sebopeho sa faele ea ZIP, ebe e theola lifaele. lifaele tse hatelitsoeng.
