their share of disadvantages. It can be said that DOS has two main drawbacks.

Since MS-DOS was originally written for a particular family of microprocessors,

it displays an incredible lack of flexibility and limited ability to meet the

needs of programmers and experienced users (Flynn & McHoes, 265). UNIX also

has several very distinct disadvantages. First, novice users find its commands

are almost cryptic which is interpreted as being non-?user-friendly?.

Second, the fact that there exist so many versions of the operating system means

that software producers must make several versions of their applications to

cover the greatest number of potential users. Third, UNIX is a large operating

system, and depending on the number of services installed and the functions

used, space used on a hard drive may vary from 20 Mb to 300 Mb (Osiris, 1).
