Lists with This Book. This book is not yet featured on Listopia. Being poor, I taught myself how to assemble and repair PCs with the aid of this book and others, obtaining parts from computer discards. Among the books referred to for these purposes, this was the best in those years. The same argument holds true for adding and increasing the size of L3 cache, as many recent processors from AMD and some from Intel have done. It is the framework in which the engine rests and is its connection to the outside world.

The chipset is the frame, suspension, steering, wheels and tires, transmission, drive shaft, differential, and brakes.

The chassis in your car is what gets the power to the ground, allowing the vehicle to start, stop, and corner. In the PC, the chipset represents the connection between the processor and everything else. If you think of the processor as the brain, the chipset is the spine and central nervous system.

The API varies according to the OS you are using and consists of the various commands and functions the OS can perform for an application. For example, an application can call on the OS to load or save a file. This prevents the application itself from having to know how to read the disk, send data to a printer, or perform any other of the many functions the OS can provide. Because the application is completely insulated from the hardware, you can essentially run the same applications on different machines; the application is designed to talk to the OS rather than the hardware.

As such, the OS never talks to the hardware directly; instead, it must always go through the appropriate drivers. This provides a consistent way to talk to the hardware. Limiting how far apart two flux transitions can be ensures that the clocks in the devices remain in sync.

These skyscraper-sized heads would float on a cushion of air that to scale would be only 5mm thick about 0. Two subtypes of this technology are used in commercially available SSDs: MLC doubles or more the density, and consequently lowers the cost, but this comes at a penalty in performance and usable life. SSDs are available using either technology, with SLC versions offering higher performance, lower capacity, and higher cost.

An interesting fact is that in a 56x CAV constant angular velocity drive, when the outer part of the track is being read, the data moves at an actual speed of Jun 06, Dylan rated it really liked it. I am a huge fan of this book. I tried reading it cover to cover, and got about half way through before quitting. It definitely isn't designed as such. It's more of a reference book, but it does that wonderfully. It goes into explicit detail on every single aspect of a computer. I was a little annoyed by just how far the book decided to go into the history of the parts.

Most of what I have read was relating to the history, which has never been a subject I particularly cared about. All in all, the I am a huge fan of this book. All in all, the book is invaluable to anyone who wants to know how a computer's hardware functions.
