system number. In this example, the binary number represents 128 + 32 + 8 + 4 + 1, or 173 in the decimal system. You can also write (or calculate) this number as follows:(128 × 1) + (64 × 0) + (32 × 1) + (16 × 0) + (8 × 1) + (4 × 1) + (2 × 0) + (1 × 1)So, two main things separat[r]

For instance, many dedicated web servers run on UNIX-based computers, such as those from Sun Microsystems, IBM, Hewlett-Packard, and other vendors.A number of features distinguish a true server-class computer from a more pedestrian client computer, including the following:N Built-in redundancy with[r]

were to think about a desktop computer in this way, its hardware would be the lowest layer, and the operating system drivers—the next-higher layer—would rely on the lowest layer to do their job. The operating system itself, the next-higher layer, would rely on both of the lower layers working proper[r]

In a nutshell, choose a peer-to-peer network for smaller networks with fewer than 10 to 15 users, and choose a client/server network for anything larger. Because most networks are built on a client/server concept, this book generally assumes such a network.Learning Network FeaturesNow that you know[r]
