Answer:-

Operating system software required to make a computer functional.

Like: - Windows,

[{"selector":"#anim-017c647e-a72d-4472-af98-3d2420ec4e12","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}]

Linux,

[{"selector":"#anim-e181073a-f643-481b-a29b-703b613d0296","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}]

Macintosh,

[{"selector":"#anim-d6bae6f2-85cc-4b35-b279-f1b58512c0c3","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}]

Ubuntu, Fedora, Android, iOS, etc.

[{"selector":"#anim-758ec887-45d8-4c82-aaec-0835c18b7813","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}] [{"selector":"#anim-d14965f7-e642-49f9-bbd4-e7bb645b28a3","keyframes":{"transform":["translate3d(0px, 125.32122%, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.2, 0.6, 0.0, 1)","fill":"both"}]

Its two primary functions are:-

[{"selector":"#anim-13bd3a86-7abe-4d63-9c9c-cf0e2483c4e1","keyframes":{"transform":["translate3d(-179.24528%, 0px, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-e653139e-08ac-4840-aaa8-92af5bc523e0","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-cdba3a72-dee1-4275-9e7b-4c6b538ce1bf","keyframes":{"transform":["scale(0.15)","scale(1)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"forwards"}] [{"selector":"#anim-44b1190f-4e0e-4bec-9ef1-3aaafb8e9993","keyframes":{"transform":["scale(1)","scale(1.5)","scale(0.95)","scale(1)"],"offset":[0,0.33,0.66,1]},"delay":0,"duration":1450,"easing":"ease-in-out","fill":"both","iterations":1}]

The operating system manages other application programs.

[{"selector":"#anim-49246742-bd44-4701-8d9d-8e0c1709e399","keyframes":{"transform":["translate3d(-116.19048%, 0px, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-57430e5c-0a43-4017-8aaa-b733bee3bd8a","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-359a7dd9-61cd-434a-b4ed-8d9958e40fbe","keyframes":{"transform":["scale(0.15)","scale(1)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"forwards"}]

Provides access and security to the users of the system.

[{"selector":"#anim-45c347e0-381a-4f0b-8cdc-6f70ad9e73a1","keyframes":{"transform":["translate3d(-116.19048%, 0px, 0)","translate3d(0px, 0px, 0)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-e5f54e06-42d1-42f5-89a6-87268191409a","keyframes":{"opacity":[0,1]},"delay":0,"duration":600,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"both"}] [{"selector":"#anim-c6b439bb-382f-42b0-bfc2-5e6d1cfb6591","keyframes":{"transform":["scale(0.15)","scale(1)"]},"delay":0,"duration":600,"easing":"cubic-bezier(0.4, 0.4, 0.0, 1)","fill":"forwards"}]
