See signal-to-noise ratio. Fundamental physical limits such as the shot noise in components limits the resolution of analogue signals. In digital electronics additional precision is obtained by using additional digits to represent the signal; the practical limit in the number of digits is determined by the performance of the analogue-to-digital converter (ADC), since digital operations can usually be performed without loss of precision. The ADC takes an analogue signal and changes into a series of binary numbers. The ADC may be used in simple digital display devices e. g. thermometers, light meters but it may also be used in digital sound recording and in data acquisition.

Which of the following facts are in common between both of the Ethernet standards discussed in this chapter, 10BASE-T and 100BASE-T? (Choose two answers.) a,b 8.
A word processor may also refer to a stand-alone computer unit similar to a typewriter, but frequently including technological advancements such as a screen, advanced formatting and printing options, and the ability to save documents onto memory cards or diskettes. Word processors almost invariably allowed the user to choose between standard typing and word processing modes by way of a switch. Such word processors should not be confused with an electric typewriter shows the graphical user interface of the Microsoft Word
a. The battery's positive lead pulls current toward the lead. c The circuit creates a direct current. 2. A PC NIC and a switch port create one electrical circuit to use when sending data.
(Buzzle, n.d) There are many different types of application software. According to Buzzle.com, Different types of application software, application software is able to manipulate text, numbers and graphs. It can be in the form of software focused on a certain single task, like word processing, spreadsheet, or playing audio or video files. (n.d) There is word processing which allows you to create and edit documents. Database software allows you to perform database operations.
How does the representation of knowledge in computers (documents, photos, music, files etc.) differ from the representation of knowledge in humans? How are they similar? Based on the text representation is a” physical state that was created to convey information, specifying an object, event, or category or its characteristics or relations”. Knowledge is in the “inclusive sense used in cognitive psychology, information in memory about the world, ranging from the everyday to the formal; often further defined as information about the world that is likely to be true and that one has justification for believing”.
(Choose two answers.) a. Completes the electrical circuit by looping two wires together on its end b. Senses current on the circuit c. Creates current on the circuit d. Removes noise from the circuit 4. A PC NIC and a switch port create one electrical circuit to use when sending data from the PC to the switch.
DataQuest Properties of Solutions: Electrolytes and Non-Electrolytes 22 In this experiment, you will discover some properties of strong electrolytes, weak electrolytes, and non-electrolytes by observing the behavior of these substances in aqueous solutions. You will determine these properties using a Conductivity Probe. When the probe is placed in a solution that contains ions, and thus has the ability to conduct electricity, an electrical circuit is completed across the electrodes that are located on either side of the hole near the bottom of the probe body (see Figure 1). This results in a conductivity value that can be read by a datacollection interface. The unit of conductivity used in this experiment is the microsiemens per centimeter, or µS/cm.
