DNS

Anyone who has ever used the Internet before has used The Domain Name System (DNS). Not only is DNS used on the Internet to convert easily readable names to machine readable IP addresses, but it is widely used on almost every IP based application. Virtual Training Company author Blair Rampling explains to users the details of what DNS is, how it works, and how to work with DNS clients and servers on both Microsoft Windows and Unix platforms. Prerequisites are that users have a basic knowledge of TCP/IP, Unix, and administration of Microsoft Windows. Topics include: setting up DNS Zones and Records, using DNS with Active Directory in Windows, installing and configuring BIND 9 for Unix, DNS Security, troubleshooting DNS, and much more. Third-Party DNS Tools such as Webmin, Men and Mice QuickDNS, and Incognito DNS Commander are also discussed. To start learning today, simply click on one of the movie topics below.

Data Structures and Algorithms in C++

This is an introductory course about algorithms and data structures. C++ is the programming language used in the course. The basics of this language will be reviewed before more difficult concepts are explored. VTC author and expert Dima Kassab will examine many topics, including: data design and implementation, primitive data structures (such as arrays and records), classes, templates, sorted and unsorted array-based lists, linked lists, doubly linked lists, stacks, queues, and binary search trees.
