Intelligentedu Free Computer and I.T. Books

There are more computer systems connected to the internet either directly or via local area networks than at any time in the history of technology and the numbers are growing at a rapid rate. It seems that not a month goes by without another story in the news about the internal network of a major corporation being compromised by an intruder.

The simple fact is that there really is no such thing as a truly secure system as long is it is connected to a network. If the large corporations with expensive firewalls and talented IT staff can’t always stop criminals from breaking in what chance do the rest of us have?

Fortunately all is not lost and we do not have to pull the network cables out of the back of our computer systems. With careful planning and system configuration it is quite possible to create a secure environment that will cause the hacker to move on to the next, easier target without rendering the entire system useless.  This free online book will teach you how to secure your computer and network again intrusions and attacks.

The Standard Template Library, or STL, is a C++ (cplusplus)library of container classes, algorithms, and iterators; it provides many of the basic algorithms and data structures of computer science. The STL is a generic library, meaning that its components are heavily parameterized: almost every component in the STL is a template. You should make sure that you understand how templates work in C++ before you use the STL. The Standard Template Library Programmer's Guide will show you how to use these classes, algorithms and iterators when coding in the C++ programming language. You can download the full manual, and also available are Frequently Asked Questions to help and guide you.
