Mene ne wata cutar a kwamfuta

Zai yiwu babu irin wannan mutum wanda ba zai san abin da wata cutar ne. Chilly kaka da sanyi hunturu - da saba lokaci domin cutar cututtuka. High yanayin jiki, asarar lamarinsa - duk wannan shi ne quite saba da saba. Likitoci sun dogon aikatã game da tambayar abin da wata cutar ne. Wannan shi ne mafi sauki kwayoyin halittar, haddasa kamuwa da kwayar haifa su nasa kwafin. A gaskiya ma, cikin cell kanta saninsa fara nuna sabon ƙarni na asali cutar. By nazarin abin da virus, sau da yawa kula da cewa da tsarin ne don haka m cewa shi da kansa kamar rai gabar za a iya kwatanta su da tsarin kwamfuta .... Lalle ne, misalin ne a fili gani. Duk wani Gudun shirin "sa" kwamfuta da aka gyara aiki daidai da buri na shirye-shiryen, wanda Ya halitta shi. Yana da wannan kama shi ne dalilin da, saboda wanda karamin sashi na dijital code da aka kira a kwamfuta cutar.

Za ka iya ji sau da yawa da kalmomin nan "kwamfyutar tsince cutar." Menene wannan yake nufi? Bari mu dubi wani sosai na kowa halin da ake ciki. Da zarar mai shi daga cikin kwamfutar tafi-da-gidanka zo daya da kuma kawo a kan wani flash drive ga wasu bayanai, sauke daga intanet. Wannan na iya zama wani shirin, direba, tsarin library. Wannan mutum ma bai zargin cewa binary aikace-aikace wani ya kara wani karamin sashe na executable code. Running modified fayil, mai amfani aika da processor yin kawai biyu shirye-shirye - da asali da kuma ƙarin m. Kwamfuta cutar - shi ne sosai ƙari. An muhimmin batu: ta aiki ba bayyana kanta zahiri. Farko da kara code kuma amma sai - asali. Da zarar a ƙwaƙwalwar, da cutar yawanci fara clone kansa, riqon ta kwafin zuwa wasu fayiloli a kan dukkan samuwa kafofin watsa labarai. Bada jimawa ba, duk fayilolin kamuwa. Irin wannan haifuwa wajibi ne don rage hadarin da ake halakar da kuma kara da yiwuwar samun rarraba. Wannan mataki ne sosai azumi da kuma kaucewa kada a gane shi.

A kara makomar wannan ƙarin shirin dogara a kan burin da cewa sanya shi tsananta mutane. Cikakken jerin fasali jerin ne m, saboda matsalar iya zama sosai bambancin. A general, za ka iya saka da asali kwatance, wanda za a iya yi da cutar:
