I-Algorithm YokuKhonza Oza Kuqala

Emhlabeni omkhulu wesayensi yekhompiyutha nohlelo, ama-algorithms ayisisekelo kuzinqubo ezisebenza kahle nezihlelekile. Phakathi kwama-algorithms ahlukene asetshenzisiwe, i-algorithm ye-First-Come First-Served (FCFS) "Woza kuqala, anikezwe kuqala»ithatha indawo evelele. Kulesi sihloko, ngizokuhambisa ngobunkimbinkimbi be-algorithm ye-First-Come First-Served, ngichaza ukusebenza kwayo kwangaphakathi, izinhlelo zokusebenza, kanye nemithelela.

Oza Kuqala Ukukhonza: Kuyini?

I-algorithm ye-First-Come First-Served (FCFS) iyi-algorithm yokuhlela esetshenziswa izinhlelo zokusebenza nezinhlelo zekhompyutha ukuphatha kanye nokubeka phambili imisebenzi ngokusekelwe kuhlelo lokufika kwayo. Njengoba igama lisho, i-algorithm ye-FCFS icubungula imisebenzi ngendlela efika ngayo, iqinisekisa ukuthi umsebenzi wokuqala ozofika ungowokuqala okumele wenziwe.

Isebenza kanjani i-First-First-Sered Algorithm?

Ukuze uqonde ukuthi i-First Come, First Served algorithm isebenza kanjani, ake sibhekisise inqubo yayo:

  1. Ukufika Kwemisebenzi: Uma umsebenzi ungena ohlelweni, ubekwa ekugcineni kolayini.
  2. Ukwenza Umsebenzi: Umsebenzi ongaphambili kolayini wenziwe iphrosesa.
  3. Ukuqeda noma Linda: Uma umsebenzi usuwenziwe, ingaqedela ukwenziwa kwayo noma ilinde i- izinsiza ayatholakala.

Izinzuzo ze-Algorithm YokuQala Oza Kuqala

I-algorithm ye-First-Come First-Served inikeza izinzuzo ezimbalwa ezimweni ezithile:

  • Kulula futhi Kulula Ukukusebenzisa: I-algorithm ye-FCFS kulula ukuyiqonda nokusebenzisa, okuyenza ibe yinhle kakhulu kwabaqalayo.
  • Ukulingana: Njengoba imisebenzi yenziwa ngendlela efika ngayo, i-algorithm ye-FCFS iqinisekisa ukusatshalaliswa okufanele kwezinsiza.
  • Ukungabikho Kwendlala: I-algorithm ye-FCFS igwema indlala, njengoba ungekho umsebenzi obambezeleka unomphela noma oweqiwa.

Imikhawulo ye-First-come, First-served Algorithm

Nakuba i-algorithm ye-FCFS inokufaneleka kwayo, nayo inakho Imikhawulo engase ithinte ukusebenza kwayo ezimweni ezithile:

  • I-Convoy Effect: Uma umsebenzi othatha isikhathi eside ufika ngaphambi kwemisebenzi emifushane, ungakha "umphumela we-convoy" lapho imisebenzi yakamuva ibambezeleka, okuholela ekusetshenzisweni okungalungile kwezisetshenziswa.
  • Ayisebenzi Izinqubo Ezinde: I-algorithm ye-FCFS ingase ingazifaneli izimo lapho imisebenzi ehlala isikhathi eside ilawula iphrosesa, ibangele ukubambezeleka kweminye imisebenzi kulayini.
  • Ukushoda kokubeka phambili: I-algorithm ye-FCFS ayicabangi ukubaluleka komsebenzi, okungabangela ukubambezeleka ekwenzeni imisebenzi ebalulekile.

Izicelo Zomhlaba Wangempela Ze-Algorithm YokuKhonza Oza Kuqala

I-algorithm yokuza Kuqala-Ukukhonza ithola izinhlelo zokusebenza ezisebenzayo emikhakheni eyahlukene, njenge:

  • Izinhlelo zokusebenza: I-FCFS ivamise ukusetshenziswa ezinhlelweni zokusebenza ukuphatha ukuhlela umsebenzi, ukuqinisekisa a ukwabiwa kwezinsiza ngendlela efanele.
  • Amasistimu Amathikithi: Kuzinhlelo zamathikithi, i-algorithm ye-FCFS isetshenziselwa ukucubungula izicelo zekhasimende ngendlela ezitholwa ngayo.
  • Izindawo zokudlela kanye nezimboni zesevisi: I-FCFS iwumkhuba ojwayelekile ezindaweni zokudlela nezimboni zesevisi, lapho amakhasimende ehlinzekwa khona ngokuthi ofike kuqala, anikele kuqala.

Ukusetshenziswa Kwe-algorithm YokuQala Oza Kuqala

Ukuze uqonde kangcono i-algorithm ye-FCFS, ake sicabangele isibonelo esilula. Ake sithi sinomugqa womsebenzi onezikhathi zokufika nezikhathi zokwenza njengoba kukhonjisiwe kuthebula elilandelayo:

  Izinhlobo zama-algorithms ku-Computer Science
Umsebenzi wasekhaya Isikhathi Sokufika Isikhathi sokwenza
P1 0 4
P2 1 3
P3 2 2
P4 3 1

Ngokusebenzisa i-algorithm ye-FCFS, imisebenzi izokwenziwa ngohlelo olulandelayo:

  1. P1 ifika ngesikhathi 0 futhi igijima amayunithi ama-4.
  2. P2 ifika ngesikhathi esingu-1, kodwa ilinda i-P1 ukuthi iqedele ukubulawa kwayo. Isebenza amayunithi ama-3.
  3. P3 ifika ngesikhathi sesi-2, kodwa ilinda kokubili i-P1 ne-P2 ukuze iqedele ukubulawa kwayo. Isebenza amayunithi ama-2.
  4. P4 ifika ngesikhathi sesi-3, kodwa ilinda i-P1, i-P2, ne-P3 ukuze iqedele ukubulawa kwayo. Isebenza iyunithi engu-1.
