CHAPTER 1 – Introduction To Networking • Connection to the internet can be broken down into: 1. Physical connection – to a network is made by inserting a specialised expansion card 2. Logical connection – uses standards called protocols. (TCP/IP) 3. Applications – the application that interprets the data & displays the information in an understandable format is the last part of the connection. (FTP) • When selecting a NIC for a network, consider the following:

president 1919-1943 and Henry's grandson Henry Ford II led the company 1945–1979, reviving its fortunes considerably. Its stock was first publicly traded in 1956. Ford acquired the British automaker Jaguar in 1989 -1990, bought the rental car company Hertz Corp. in 1994, and purchased the automobile division of Volvo in 1999. Later acquisitions included Aston Martin and the Land Rover brand of sport utility vehicles. Ford also owns a significant share of the Mazda Motor Corporation because of financial

wavelength because the sound source is vibrating at a faster speed. Meaning more complete back and forth vibrations are occurring in a quicker amount of time, whereas when the frequency is lower the wavelength is longer. Frequency is measured in hertz (Hz.) and to distinguish the frequency you need to know how many vibrations occur in an exact amount of time, for example if an object’s particles vibrate 256 times in one second, then the frequency is 256 Hz. The frequency that an instrument creates

Electromagnetic waves At this point in the course we'll move into optics. This might seem like a separate topic from electricity and magnetism, but optics is really a sub-topic of electricity and magnetism. This is because optics deals with the behavior of light, and light is one example of an electromagnetic wave. Light and other electromagnetic waves Light is not the only example of an electromagnetic wave. Other electromagnetic waves include the microwaves you use to heat up leftovers for

CHAPTER 1 — BASIC RADAR PRINCIPLES AND GENERAL CHARACTERISTICS INTRODUCTION The word radar is an acronym derived from the phrase RAdio Detection And Ranging and applies to electronic equipment designed for detecting and tracking objects (targets) at considerable distances. The basic principle behind radar is simple - extremely short bursts of radio energy (traveling at the speed of light) are transmitted, reflected off a target and then returned as an echo. Radar makes use of a phenomenon

and recreation can cause annoyance, disturb sleep and affect health. Thus, sound is a potentially serious pollutant and threat to environmental health. The response of the human ear to sound depends both on the sound frequency (measure in Hertz, Hz) and the sound pressure, measured in decibels (dB). A normal ear in healthy young person can detect sounds with frequencies from 20Hz to 20,000 Hz. Noise measurements are expressed by the term Sound Pressure Level (SPL) which is logarithmic
