Query: This is a very easy to understand book

This book doesn't contain any logic gate level designs but covers general computer organisation issues thoroughly. It is only 670 pages approximately and covers instruction set design, CPU structure (ALU + control unit), I/O (such as SCSI, FireWire and RAID), Bus systems (PCI, Futurebus+) and operating systems etc. There are numerous comparisons made between Intel Pentium and PowerPC. It is a good book to start with a very good bibliography for more detailed books on each chapter's subject.
