This revised edition has more breadth and depth of coverage than the first edition. Information Technology: An Introduction for Today's 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.
