[Page 367 (continued)] Problems 1. A 1x DVD reader can deliver data at a rate of 1.32 MB/sec. What is the highest speed DVD drive that could be connected over a USB 2.0 connection without losing data? 2. Many disks contain an ECC at the end of each sector. If the ECC is wrong, what […]

[Page 229 (continued)] 3.2. Principles of I/O Software Let us now turn away from the I/O hardware and look at the I/O software. First we will look at the goals of the I/O software and then at the different ways I/O can be done from the point of view of the operating system. 3.2.1. Goals […]
