U današnje vrijeme virtualizacija obuhvaća pojmove kao što su virtualizacija servera, virtualizacija računara, virtualizacija desktopa, virtualizacija aplikacija, te u najširem smislu – virtualizacija poslovanja. Na nivou poslovnih korisnika virtualizacija je postala standard zbog uštede u troškovima ali i bezbjednosti informacija i sistema. Osim poslovnih korisnika zabilježeno je i veliko interesovanje primjene virtualizacije među kućnim korisnicima. Virtualizacija kao tehnologija ima dugu historiju i datira još od kasnih šezdesetih godina prošlog stoljeća. Virtualizacijom se postiže bolja iskorištenost računarskih infrastruktura i na taj način omogućava se njihovo istovremeno korištenje u različitim sistemima. Virtualizacijske tehnologije svoj razvoj započinju 1960-tih godina u IBM-u. Radi se o projektu M44/44X čiji je cilj bio logički podijeliti fizički sustav na različite virtualne …show more content…

Izgradnja jednog centra košta košta nekoliko miliona američkih dolara te je jasno koliko se može uštediti korištenjem virtualizacije. 2.1.3.Energija Velike kompanije većinom ne daju preveliku važnost potrošnji električne energije jer smatraju da je ona vječno dostupna, ali krize u isporuci električne energije koje su se desile u Kaliforniji 2000-te godine natjerale su ih da promjene svoje mišljenje i počnu razmišljati kako mogu uštedjeti ali i efikasnije trošiti električnu energiju. Ubrzo je došlo i do podizanja svijesti organizacija za zaštitu okoliša te su tražili smanjenje enormnog koristenja električne energije. Već smo spomenuli da jedan neiskorišten računar troši kao i onaj koji radi sa punim kapacitetom tako da štednja električne energije znači i finansijska ušteda. 3. PRIMJENE VIRTUALIZACIJE Postoji više načina za primjenu virtualizacije, no ipak možemo ih podijeliti u 3 grupe: virtualizacija računarskog sistema, virtualizacija memorija i virtualizacija programa. U današnje vrijeme najviše se upotrebljava virtualizacija računarskog

    Yusef Komunyakaa, the author of “Facing It,” is a Vietnam Veteran who appears to write as a means to express his grief, pain, and postwar experiences. Being a Veteran myself and having been to the Vietnam Memorial in Washington, D.C. several times, I empathize with Komunyakaa. The first thing I noticed upon walking down the path to the monument was how quiet and peaceful it was, yet the sorrow and pain was deeply rooted. I located the names of family, friends, and the MIA Marine’s name “CAPT RICHARD R. KANE” on my MIA/POW bracelet. This experience sent chills throughout my body and was emotionally overwhelming.

The use of virtual reality technology also creates a tension between the natural and the artificial, as Jesse experiences insert example. To continue, paradox can bd seen in the idea of a cultural experience that is meant to be both authentic and universal. The virtual reality company markets its experience as “authentic Indian” while at the same time making it accessible to anyone through technology, regardless of race, gender, and ethnicity.

    To improve network communications between stores, head offices. Combine all stock databases into a single system on head office server, so staff can view the amount of stock and access most recent up to date data. This would drastically improve the communications between the several stores. To achieve this, all the individual LANS (Local area Network) from the stores must be connected to create a Wide area network, thus this WAN can be accessed through Telecommunications lease lines across the internet. Though for PVMS this type of method is expensive, but will significantly benefit from this change.
