quick tour of the modern personal computer
By W Boudville
The book describes in simple terms for a complete neophyte the hardware and software of a typical computer. The emphasis is on explaining a personal computer, as this is now the most common explicit computing platform that the average person is likely to encounter.
The text gives a quick history, where we see how rapid progress was made, and how most modern computers use the Neumann architecture. Moore's Law is outlined. You should appreciate how this has come to encapsulate and summarise the last 40 years of hardware improvements.
Roughly, the first half of the book covers hardware. The basic parts that are on a motherboard are covered, as well as the possible types of buses that might be present. Devices that can be connected to the input/output ports are not neglected. Of these, the most important is clearly the monitor. The different types of monitors are given, like the CRT and the LCD displays. You also need to understand the key role of the CPU, and how clock speeds can vary its performance. The concept of overclocking, where a dedicated gamer might crank up the speed of the computer clock, ties in to this, and is useful to know.
A chapter goes over the use of memory chips. Here is also where you can drastically affect [hopefully improve] the performance of your machine, by adding more memory. This is more useful than adding more disk, because access times for the latter are in microseconds, while memory access times can be in 10s of nanoseconds. Just understanding at a qualitative level the differences in access times, and how these arise from different underlying physical mechanisms, can be a great help in understanding how to optimise the overall performance.
Software is the remit of the second half of the book. A relatively large amount of space discusses the low level BIOS. This is at a level below the operating system, and if you are going to administer computers, experience in using and even installing a BIOS is highly recommended.
Moving upwards, the book strikes an ecumenical tone about the different operating systems that might be present. Three types are talked about - Microsoft Windows, linux and the Mac OS X. Keep in mind that if you understand the linux sections, you now also know [at least at a qualitative level] about the different Unixes. Indeed, the Mac's operating system is a Unix variant.
The book ends with a chapter on networks. Well nowadays, it's essentially mostly some kind of Internet. Much of the chapter explains common networking hardware. So that, for example, you know the difference between an RJ-45 cable and a USB cable.

A GREAT CERTIFICATION RESOURCE!!
By COSMIC TRAVELER
Are you an entry-level IT student? If you are, then this book is for you! The Pearson Certification Team, has done an outstanding job of writing a book which acts as a stepping stone to certification from organizations such as CompTIA, Microsoft and Cisco.
The team begins with a basic account of the history of computers through to today’s modern computers. Then, the team discusses the basics of computer math, including the numbering systems used by computers, basic Boolean algebra, and how to measure data transfer. They continue by covering input and output devices; their connections and the ports they connect to; and, how those ports communicate with the central processing unit.
Then, the team shows you how to install adapter cards into a motherboard. They then cover the brain of the computer: the CPU. Next, the team delves into random access memory, magnetic hard drives, and optical drives. The team continues by showing you how the computer boots with the help of the BIOS. Then, they examine the various Windows operating systems and their interfaces and tools. Next, the team describes the basic tools that should be part of every PC technician’s toolkit. They also discuss the tools you need, the concepts you should know, and how to troubleshoot in a logical and progressive way. Finally, the team shows you the basics of computer networking, how to connect to networks, Internet technologies, and of course, the all-powerful TCP/IP.
The number one goal of this excellent book is to establish the groundwork of computer knowledge and hands-on skills for the reader. In fact, this great book is designed in such a way as to offer an easy transition to future certification studies.

Should be the first book read by a computer novice;well written!
By Capt Smith
As stated in the introduction, "The number one goal of this book is to establish the groundwork of computer knowledge and hands-on skills for the reader." Starting with an introduction to computers the book provides a very clear and easily read foundation of basic computer knowledge. From tubes to transistors to integrated circuits the book provides a step-by-step progression of the major components of the personal computer.
The first half of the book is devoted to understanding: (1) input/output (I/O) ports and devices; (2) motherboards and buses; (3) the CPU; and, (4) memory and storage. The following chapters delve into the processes of the basic input/output system (BIOS), operating systems, security, troubleshooting and networks.
One of the highlights of this book is the excellent selection and formatting of pictures and graphics used throughout the book to illustrate the topic areas. Additionally, there is a chapter review at the end of each chapter which tests the readers recall of the concepts described. Answers and explanations to these questions provide additional instruction and help to the reader.
As an information security professional, I was pleased to see the chapter on basic security. I would have preferred more information provided to the reader about creating complex passwords, access control/privilege escalation, and configuring wireless security in routers. I would also have liked to have seen the comment that security is a constantly changing dynamic balancing business requirements, resources, and risk.
Much of the information and content in the book is current and relevant to students of ages. There is an excellent section on USB 3.0 (Hi-Speed USB).
Overall, I found this book to be an outstanding introduction for those who want to learn about computers from the ground up. In my opinion the authors clearly achieved the goal they set for themselves. This would make a great high-school intro to computers textbook. Highly Recommended!!!
