Before there were computers, there were algorithms. But now that there are computers, there are even more algorithms, and algorithms lie at the heart of computing. This book provides a comprehensive introduction to the modern study of computer algorithms. It presents many algorithms and covers them in considerable depth, yet makes their design and analysis accessible to all levels of readers. In this book, the authors tried to keep explanations elementary without sacrificing depth of coverage or mathematical rigor. Each chapter presents an algorithm, a design technique, an application area, or a related topic. Algorithms are described in English and in a pseudocode designed to be readable by anyone who has done a little programming. The book contains 244 figures — many with multiple parts — illustrating how the algorithms work. It also includes careful analysis of the running times of all algorithms. In this third edition, the entire book once again updated including changes cove

This book is meant to help the reader learn how to program in C. It is the definitive reference guide, now in a second edition. Although the first edition was written in 1978, it continues to be a worldwide best-seller. This second edition brings the classic original up to date to include the ANSI standard. For evolution of the planet earth and our modern understanding of biology, there was Darwin's Origin of the Species. For mathematics, there was Newton's Philosophiæ Naturalis Principia Mathematica. Well, for the internet, for Facebook, for LinkedIn, Twitter, Instgram, Snapchat, WhatsApp, Pornhub and even the odious website for Justin Bieber would never have existed without Kernigan and Ritchie (more affectionately known as K&R)'s classic, The C Programming Language. What language was TCP/IP written in? C. What language inspired both C++ and Java (and the abominable C#)? C. What language are most libraries on most operating systems written in if not assembler? C.

This is Herb's step-by-step introduction to Java, updated for Java SE 8 (JDK 8). If you are just learning Java, then this is the book for you.  It starts at the beginning, explaining the history of Java, why it's important to the Web, and how it relates to the world of programming at large.  You then learn how to obtain the Java Development Kit (JDK) and write your first Java program. Next, it's on to the Java fundamentals, including data types, operators, control statements, classes, objects, and methods.  You'll then progress to more advanced topics, such as inheritance, exception handling, the I/O system, multithreading,  applets, and lambda expressions. Also included is coverage of some of Java's most powerful features, such as generics, autoboxing, enumerations, and static import.  An introduction to JavaFX, Java's newest GUI framework, is also included. *** TO REVIEW BOOK *** (click below) *** TO REVIEW SOURCE CODE PROBLEM  SOLUTIO

Have you ever looked inside a computer case, or seen pictures of the inside of one? The small parts may look complicated, but the inside of a computer case isn't really all that mysterious. This lesson will help you master some of the basic terminologies and understand a bit more about what goes on inside a computer. Watch the video below to learn about what's inside a desktop computer.

A computer is a device that accepts information (in the form of digitized data) and manipulates it for some result based on a program or sequence of instructions on how the data is to be processed. Complex computers also include the means for storing data (including the program, which is also a form of data) for some necessary duration. A program may be invariable and built into the computer (and called logic circuitry as it is on microprocessors) or different programs may be provided to the computer (loaded into its storage and then started by an administrator or user). Today's computers have both kinds of programming. Watch the video below to learn about different types of computers.
