List 3 differences between UNIX and Windows:

answer

1)No GUI 2)Use of command line In UNIX/LINUX the forward slash / is used instead of the backward slash 3)No device letters like C: or A: are used in UNIX/LINUX. The UNIX/LINUX user typically does not know or care what device is being used to store files. 4)The UNIX/LINUX user does not store files on floppy disks or print them out on a local printer. Files are stored on the server's hard disk and printed out on the server's shared printer 5)RedHat LINUX can be used from any computer with an Internet connection using Telnet. You do not need to be on campus. 6)UNIX/LINUX is case-sensitive , so a file named Notes is different from a file named notes 7)To access RedHat LINUX, each user must have a User ID and password. There is no general use of the RedHat LINUX machines—only staff and students enrolled in CS and CNIT courses can use it. 8)UNIX/LINUX files do not have filename extensions like WINDOWS files do. The period is just another character and can be used in a filename, but it does not have any special significance to UNIX/LINUX. However, filenames that start with a period are hidden files UNIX/LINUX uses when you log in, and they are not normally modified by users. 9)UNIX/LINUX files are placed in directories. WINDOWS files are placed in folders . The two terms have the same meaning.
