If it’s computer files, that would be System Software and Application software.
“The System Software is the programs that allow the computer to function and access the functionality of the hardware. Systems software sole function is the control of the operation of the computer.
Applications software is the term used for programs that enable the user to achieve specific tasks such as create a document, use a database or produce a spreadsheet.”
A time bomb virus is a virus that is triggered on a certain date. It is a malicious program that is designed to release virus unto a system. Once the time has arrived, it will automatically start working what it is programmed to do since any virus could do anything depending on what it is designed to do.
The options listed are not related to the question. and if they were related in any sense then I would say the cheapest thing on the list is a phone card so I guess you can buy that and save the most for your travel as you can use phone cards anywhere as they have 1800 numbers which are free from any public phone.
Answer:
B. Virtual reality
Explanation:
In a virtual reality context, the visual and auditory senses of the user are fed by data (images, sounds) from the computer using a goggle and earphones. That allows the person to be totally cut off her real physical environment and be totally immersed into the world (reality) managed by the computer.
Not to be confused with<u> augmented reality</u>, where the physical reality and perception of it aren't changed... but an additional layer of information is added on top of it. Like pointing your phone camera to a building and getting information about the building displayed on your phone.
