This revised edition has more breadth and depth of coverage than the first edition. Information Technology: An Introduction for Todays Digital World introduces undergraduate students to a wide variety of concepts that they will encounter throughout their IT studies and careers.

The features of this edition include:











Introductory system administration coverage of Windows 10 and Linux (Red Hat 7), both as general concepts and with specific hands-on instruction





Coverage of programming and shell scripting, demonstrated through example code in several popular languages





Updated information on modern IT careers





Computer networks, including more content on cloud computing





Improved coverage of computer security





Ancillary material that includes a lab manual for hands-on exercises

Suitable for any introductory IT course, this classroom-tested text presents many of the topics recommended by the ACM Special Interest Group on IT Education (SIGITE). It offers a far more detailed examination of the computer and IT fields than computer literacy texts, focusing on concepts essential to all IT professionals from system administration to scripting to computer organization. Four chapters are dedicated to the Windows and Linux operating systems so that students can gain hands-on experience with operating systems that they will deal with in the real world.
