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:
0.127 miles ; 5.458 *10^8 miles
Explanation:
Number of bytes needed to store a page = 2000
Number of pages (Harry Potter's book) = 800
Total memory required to store entire book = (2000 * 800) = 1600000 = 16 * 10^5 bytes
Hence,
1 byte of memory will store : (height of each book / memory size of each book)
= 3 ÷ 16 * 10^5
= 1.875 * 10^-6
For 32 bit memory space :
(1.875 * 10^-6 * 2^32) = 8053.06368 inches
1 inch = 1.578 * 10^-5 mile
8053.06368 inches = 8053.06368 * (1.578 * 10^-5) = 0.1270773448704 miles
= 0.127 miles
For 64 bit memory size :
(1.875 * 10^-6 * (2^64)) = 3.45876 * 10^13 inches
(3.45876 * 10^13) * (1.578 * 10^-5)
= 5.458 *10^8 miles
