| - | An operating system (OS), in its most general sense, is software that allows a user to run other [[dido:public:ra:xapend:xapend.a_glossary:a:application|applications]] in a computing device, as well as Virtual Machine applications, which emulate another computer. While it is possible for a software application to [[dido:public:ra:xapend:xapend.a_glossary:i:interface|interface]] directly with hardware, it is not advisable from a portability or lifecycle perspective. Software applications that access hardware resources or other computer components directly pose a security risk. | + | An [[dido:public:ra:xapend:xapend.a_glossary:o:os]], in its most general sense, is software that allows a user to run other [[dido:public:ra:xapend:xapend.a_glossary:a:application|applications]] in a computing device, as well as [[dido:public:ra:xapend:xapend.a_glossary:v:vm|Virtual Machine]] applications, which emulate another computer.
