This engaging and accessible text addresses the fundamental question: What Is Computer Science? Rather than supplying a brief overview of every relevant topic, the book showcases a set of representative concepts broadly connected by the theme of information security. The presentation of each topic can be treated as a "mini" lecture course, demonstrating how it allows us to solve real problems, as well as how it relates to other subjects. The discussions are further supported by numerous examples and practical hands-on exercises, which together will be sure to whet your appetite for the many fascinating aspects of computer science. Topics and features: Presents a concise introduction to the study of algorithms, and describes how computers work using the example of computer viruses Introduces the concepts of data compression, and error detection and correction Highlights the role of data structures, and how their design can have a profound influence on algorithms that operate on them Explores the topic of web-search, with a specific focus on examples drawn from cryptography and information security Reviews both historic and modern cryptographic schemes, examines how a physical system can leak information, and discusses the idea of randomness Investigates the science of steganography, the hiding of secret data within non-secret data Provides additional supplementary material at an associated website This easy-to-read textbook is an ideal introduction to the study of computer science for students beginning on, or contemplating taking, an undergraduate degree. Teachers wishing to offer a primer on the field will also find the book an excellent educational resource. 410 0$aUndergraduate Topics in Computer Science,$x2197-1781 606 $aComputer science 606 $aCryptography 606 $aData encryption (Computer science) 606 $aAlgorithms 606 $aEducation$xData processing 606 $aComputer Science 606 $aCryptology 606 $aAlgorithms 606 $aComputers and Education 615 0$aComputer science. 615 0$aCryptography. 615 0$aData encryption (Computer science). 615 0$aAlgorithms. 615 0$aEducation$xData processing. 615 14$aComputer Science. 615 24$aCryptology. 615 24$aAlgorithms. 615 24$aComputers and Education. 676 $a004.0 700 $aPage$b Daniel$4aut$4http://id.loc.gov/vocabulary/relators/aut$0933787 702 $aSmart$b Nigel$4aut$4http://id.loc.gov/vocabulary/relators/aut 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910298570503321 996 $aWhat Is Computer Science$92102232 997 $aUNINA
