Answer:
Low Vision Aid for Computer Users
Explanation:
Visually impaired people can use the same low vision aids for viewing a computer screen as they do for regular reading activities. These include eyeglass-mounted magnifiers, handheld magnifiers and stand-alone magnifiers. But also, special software has been developed to display content on the screens of computers and other digital devices in large print. Other applications can read text and other visual content aloud with a synthetic voice. These adaptive low vision devices let partially sighted people do the same computer-related tasks as fully sighted people — such as word processing, creating and using spreadsheets and viewing web pages online.
Answer:(C) Anyone with access to the personal computers could log on to the mainframe.
Explanation:
It is no doubt that log on procedures are cumbersome so what most users do is that they store log on sequences in their computer so that they could use the main frame facilities whenever they access it the second time.
Here we have to identify the associated risk with this approach.
This process could lead to access of the computer system to users and thereby making all the data available in the system vulnerable. So option C is correct.
option (A) is incorrect as the back up option who also be affected when the system is accessible to anyone.
option (B) is incorrect because it has nothing to do anything with training of the personnel.
option (D) is incorrect because it one has nothing to do with the physical system what vulnerable reside is inside the system.
Answer: Cyber warfare is a real threat since being able to hack another computer especially a countries computer with lots of info in their weaknesses can lead to their downfall. Since they can even possibly if their skilled enough hack their entire data base system and leak it to the public and that wouldn't be good for them not in a single possible way. That's the reason it's dangerous not only that but also because they can access their servers; which can let them access anything online from the whole country including banking information military info which can let them know which area there gonna go to next equipment there gonna bring and where they're gonna launch missiles, bombs, even nukes if they decide to launch one. And being able to hijack the computer that launches the nukes can make the hacker launch the nuke to a different place or launch the nuke on the country trying to launch the nuke.
