Ekosustav Denicija Ekosustav je biolo²ki prostor izgražen od svih ºivih organizama koji nastanjuju odreženo podru je, kao i ne-ºivih, opipljivih sastavnih dijelova okoli²a s kojima su organizmi u kontaktu, poput zraka, tla, vode i sun eve svjetlosti.

Servisi ekosustava snabdijevanje poput stvaranja hrane i voda regulacija poput kontrole klime i oboljenja podr²ka poput hranidbenog ciklusa i opra²ivanja biljaka kultura poput duhovnih i rekreacijskih koristi

Ekosustav softvera

Softver Denicija (Slobodni softver) je softver koji je licenciran na na in koji omogu ava njegovo kori²tenje, prou avanje i izmjenu bez ograni enja, te koji se moºe kopirati i distribuirati u izmijenjenom ili orginalnom obliku. Denicija (Privatni softver) je softver koji je licenciran isklju ivim pravom njegovog vlasnika. Kupac dobiva pravo kori²tenja softvera samo pod odreženim uvjetima ²to zabranjuje izmjenu, distribuciju, ili obrnuti inºenjering

Ekosustav softvera Denicija (Otvoreni ekosustav) je heterogeni ekosustav s velikim brojem razli itih softvera koji koriste otvorene i standardizirane protokole za komunikaciju i razmjenu podataka. Denicija (Privatni ekosustav) je homogeni ekosustav izgražen oko jedinstvenog softvera koji pruºa jedinstveni dobavlja i koristi zatvorene formate i protokole za komunikaciju i razmjenu podataka.

Osnovne zablude oko slobodnog softvera nitko ne koristi slobodni softver nema podr²ke slobodni softver ne razvijaju profesionalci nije kompatibilan

Osnovne zablude oko slobodnog softvera nitko ne koristi slobodni softver INTERNET nema podr²ke podr²ka zajednice ili pla ena podr²ka vi²e od jedne tvrtke slobodni softver ne razvijaju profesionalci ve inu razvoja slobodnog softvera pla aju tvrtke nije kompatibilan zatvoreni formati su ZATVORENI!

Conclusion Otvoreni ekosustav je otporniji i brºe evoluira. Otvoreni formati i standardi su najsigurnija investicija za budu nost. Investicije u slobodni softver su investicije u lokalne poduzetnike i ekonomiju. Jednostavniji i brºi prijenos znanja. Nema nakupljanja tro²kova za licence. Svijet nije crn i bijel, nego u sivim nijansama.
