This chapter addresses the network devices found in a typical premises environment, including computers, wired and wireless local area networks (LANs), and a number of other options. We begin with an examination of a typical computer. In one way or another, the computer is the ultimate premises technology device. In one form or another, the computer appears in every device used by a customer to access the network.

For all its complexity, the typical computer only has a small number of components, as shown in Figure 4-1. These are the central processing unit (CPU), main memory, secondary memory, input/output (I/O) devices, and a parallel bus that ties all the components together. It also has two types of software that make the computer useful to a human. The first is application software such as word processors, spreadsheet applications, presentation software, and MP3 encoders. The second is the operating system that manages the goings-on within the computer, including hardware component inventory and file locations. In a sense, it is the executive assistant to the computer itself; some mainframe manufacturers refer to their operating system as the EXEC. The concept of building modular computers came about in the 1940s when Hungarian-born mathematician John Von Neumann applied the work he had done in logic and game theory to the challenge of building large electronic computers (see Figure 4-2). As one of the primary contributors to the design of the Electronic Numerical Integrator and Calculator (ENIAC), Von Neumann introduced the concept of stored program control and modular computing, the design under which all modern computers are built today. A personal computer s internals are shown in Figure 4-3.

The CPU
The CPU is the brain of the computer. Its job is to receive data input from the I/O devices (keyboard, mouse, modem, and so on), manipulate the data in some way based on a set of commands from a resident application, and package the newly gerrymandered data for presentation to a human user at another I/O device (monitor). The CPU has its own set of sub-components. These include a clock, an arithmetic-logic unit (ALU), and registers. The clock is the device that provides synchronization and timing to all devices in the computer, and it is characterized by the number of clock cycles per second it is capable of generating. These cycles are called Hertz. Modern systems today operate at 850 to 1,000 Megahertz, or MHz. The faster the clock, the faster the machine can perform computing operations. The ALU is the specialized silicon intelligence in the CPU that performs the mathematical permutations that make the CPU useful. All

functions performed by a computer word processing, spreadsheets, multimedia, videoconferencing are viewed by the computer as mathematical functions and are therefore executed as such. It is the job of the ALU to carry out these mathematical permutations. Registers are nothing more than very fast memory located close to the ALU for rapid I/O functions during execution cycles.
Main Memory
Main memory, sometimes called Random Access Memory (RAM), is another measure of the goodness of a computer today. RAM is the segment of memory in a computer used for execution space and as a place to store operating system, data, and application files that are in current use. RAM is silicon-based, solid-state memory and is extremely fast in terms of access speed. It is, however, volatile. When the PC is turned off, or power is lost, whatever information is stored in RAM disappears. When basic computer skills courses tell students to save often, this is the reason. When a computer user is writing a document in a word
