A network has to fulfill delivery, reliability, performance, and security (02/13/2011)
(...) In fact, two network connections can even interfere with each other, a phenomenon known as crosstalk. When you faintly hear someone else's phone conversation during your own, you're experiencing crosstalk.

Networking: Optical fiber and wireless (02/13/2011)

The light source in less expensive systems is a light-emitting diode, something like the light on some keyboards that indicates whether the "Caps Lock" is on. More expensive optical fiber systems have a laser as a light source. The laser is better because it produces a tightly focused beam. (...)

Sometimes the mechanism for flow control is part of the mechanism for error control. One such mechanism is called stop-and-wait, which is when the sender sends a single message and does not send another until the first message's ACK is returned. This method is slow because the sender spends most of its time waiting, not sending. (...)

Common output devices of a personal computer (02/12/2011)
(...)
An LCD is a liquid crystal display. Liquid crystal, as the name implies, has properties of both a liquid and a solid. The important feature for its use in monitors is that it turns solid when exposed to an electrical current, and it is opaque when in the solid state but clear when in the liquid state. (...)
Main memory in a PC consists of RAM (02/12/2011)
(...) Because main memories are so large, they use dynamic RAM.
RAM is divided into cells of memory called words, which may be a single byte (eight bits) or multiple bytes. Each word's location in RAM is specified by a unique address, which is just a whole number that starts from 0. (...)
Modern CPUs: Backwards compatibility, pipelining, heat dissipation (02/12/2011)
(...) For example, the registers on early Intel CPUs contained 16 bits, or 2 bytes, while later Intel CPUs required 32 bit registers.
The solution was to design the registers on later CPUs to act as both 16 bit and 32 bit registers, depending on what size data was sent to them. Back in 1965 researcher Gordon Moore wrote an article predicting that the number of transistors in a typical processor would double every two years. (...)
A closer look at some of the internal components of a PC (02/12/2011)
(...) These are small circuit boards that fit into a slot on the motherboard.
Because a video screen is constantly refreshed, the image displayed must be stored in RAM. Originally, graphics cards were just the RAM to hold the image and a device that constantly scanned through the RAM and converted the image stored there into the signals the monitor needed for display. (...)
Types of software usually used on a PC (02/12/2011)

(...) txt is the name of the file, and C:\MyDocuments is the file's logical location. On a Windows system, it means that the file is on a hard drive indicated by the letter C and that on that drive it is stored in a folder called "My Documents."
Each file is stored across various sectors on a disk. (...)
Event and output device management, security and system data management (02/12/2011)
(...)
This separation between application programs and hardware is another example of abstraction. The programs are one level of abstraction removed from the mouse and keyboard. Different keyboards and mice may have different characteristics, but only the operating system needs to deal with that. (...)
Interoperability of different pieces of hardware and software (02/12/2011)
(...)
If the programs didn't communicate in this way, then the e-mail program would need its own programming code for editing text. This capability would be redundant, and probably the e-mail program would have fewer editing features.
Similarly, the word processor might allow a spreadsheet to be displayed inside a document. (...)
Phases of software development can be combined in different ways (02/12/2011)
(...) The waterfall paradigm doesn't easily accept such changes.
Rapid Prototyping
A prototype, in engineering, is a model of a device that can be used in tests before the production of the device begins. For instance, car makers often design a prototype of a new car that can be driven at test tracks and displayed at auto shows. (...)
