need to have physical storage devices and must be able to organize the files on the computer. Understanding how these systems work is vital in itself without these functions a device cannot do its job and the user would not be able to save a file much less look for one when saved to the computer. So this Why these are very important to have. * Describe how digital devices store data: The way digital devices store data is by bits. This singe task can make any device a computer as well as process

Don Delara/IT320 IT320 Wan Technology/ Unit 4 Assignment: 4.1 1. At what layer of the OSI model does CDP operate? Data Link layer 2. What is the primary use for CDP? To discover information about directly connected Cisco devices 3. What network layer protocols can CDP provide information for? IP, Internetwork Packet Exchange (IPX), and AppleTalk 4. When CDP is enabled on an interface, a router (or switch) sends CDP advertisements on a regular basis, which list information about the

flip-flop circuit, Determine how the circuit will behave for a sequence of inputs. Be able to use a flip-flop to store a single bit. Basic Circuit Here's a basic circuit that involves just two NAND gates. There are two inputs to this circuit, X and Y. Can you generate a truth table for this circuit? * Note that there is no connection where the two wires running from the output back to the input cross. Let's address that issue of the truth table. Here is a truth

A PROGRAMMABLE LOGIC CONTROLLER (PLC) is an industrial computer control system that continuously monitors the state of input devices and makes decisions based upon a custom program to control the state of output devices. In the late 1960's PLCs were first introduced. The primary reason for designing such a device was eliminating the large cost involved in replacing the complicated relay based machine control systems. Bedford Associates (Bedford, MA) proposed something called a Modular Digital Controller

more than one cell. The larger terminal (on the left) is positive (+). Supplies electrical energy. DC = Direct Current, always flowing in one direction. Supplies electrical energy. AC = Alternating Current, continually changing direction. A safety device which will 'blow' (melt) if the current flowing through it exceeds a specified value. Two coils of wire linked by an iron core. Transformers are used to step up (increase) and step down (decrease) AC voltages. Energy is transferred between the coils

the common meaning of computer: a. That the computer is an electronic device; b. That the computer can accept input; c. That the computer are capable of processing input; d. That after processing a computer will produce an output; e. And, that output of a computer maybe stored and can be easily retrieved for future uses. Recent computer texts will also mentioned that what is being accepted as input, what is being processed and what are being outputted and stored are data.

the mixing console. A mixing console is an electronic device that is used for combining, routing, changing the level, timbre and/or dynamics of audio signals. Depending on the type of mixer, a mixer can mix either analog or digital sounds. The altered signals are then summed together in order to produce the collective output signals. In 1958, the Willi Studer Company of Switzerland manufactured one of the earliest mixing consoles. This device, called the “Studer 69,” used reel-to-reel tape and was
