This also involved gaining familiarity with how ICs must be powered and grounded
Answer: The TCP/IP protocols were initially developed as part of the research network developed by the United States Defense Advanced Research Projects Agency it was created for a number of different protocols but had many flaws and was adapted for more of a business and house hold use Lab 3.2 1 How does the abstraction of the physical layer facilitate interoperability across networks using different types of physical wires? Answer: It is according to the kind of wire and how it is made up of, E.g. Copper Fiber optics. The physical layer includes electrons. The faster this can move back and forth from one point to another, the faster data is transferred, to have proper connection is just as important as the wire themselves to make a smooth transfer.
Since the reaction time for such stimuli is usually between 150 and 350ms, it is inappropriate to use a stop watch as it lacks precision. Thus for this experiment, the student uses silent and audible switches and a clock/timer to measure reaction times to purely audible or visual stimulus. Apparatus * clock, * clicker, * Logger Pro file RT The apparatus is very simple. A clock starts when a remote trigger switch is activated. This switch can be activated with or without a sound.
Adam Workman Lab, Week #1 Balance Lab Introduction The purpose of the Balance Lab experiment was to become familiar with the ChemLab software and to become familiar with different mass measurement methods. During the experiment, three different mass measurement methods were used to determine the mass of copper slugs as well as the mass of two different unknown weights: the direct weight method, the weighing by difference method, and the average mass method using both a centigram balance and an electronic balance. Using the centigram balance, the weight of a single copper slug, in grams, is determined using both the direct weight and weight by difference methods. Likewise, using the electronic balance, the same copper slug is measured by direct weight and weighing by difference methods. Using the same electronic balance, the average mass of five copper slugs, in grams, will be determined.
75uS is the time constant used for a high-pass filter to enhance the high frequency audio before transmission to help reduce noise upon reception. The PLL is the portion of the IC which locks your chosen transmission frequency to the crystal reference X1. The PLL portion also contains an oscillator circuit which works in conjunction with the external parts of D5 and the STUB (that weird trace on the back of the board). D5 is called a varactor diode, and is a special variety of diode that is connected backwards. As a reverse DC voltage is applied across the diode, its capacitance varies.
I also liked learning more about how atomic structure and electrical charge. 3. What did you like least? The least I liked about this unit was trying to learn all the equations and the solutions. Also when doing lab work I think that it needs to show more detail due to I think with that it would be more understanding.
11. Cable Toner12. Continuity Tester- an item of electrical test equipment used to determine if an electrical path can be established between two points; that is if an electrical circuit can be made 13. Category 5e/6 cable- is a standardized cable for Gigabit Ethernet and other network physical layers that is backward compatible with the Category 5/5e and Category 3 cable standards 14. Binder Groups- Cable pairs are typically arranged under the cable sheath in binder groups 15.
In telecom closet 2, from the punch down block, to the switches, to the wall plates, and on to the offices workstation, plus one shared printer, cabling will change to Cat 5e UTP, using 1000 Base-T technology, achieving a throughput of 1000Mbps. A safety feature on Ethernet Lans, is its access method, CSMA/CD. CSMA/CD, means that your NIC checks the network to make sure it is not busy before transmitting, if two nodes do transmit at the same time having a collision, it will send out packets to inform other nodes of a data collision, then the NIC waits for the network to be inactive before retransmitting. On the
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.
