Scribe how you can tell if the cable is a straight-through cable or a crossover cable. Carefully examine the colors of the wires that you can see through the clear plastic RAJA connector. 14 What technology is used when power is transmitted on a network cable? Power over Ethernet (POE) 15. Describe the difference between a hub and a switch. A hub is a pass-through device that transmits all frames to all devices it is connected to except the device sending the frame. A switch is smarter and transmits frames only to the device to which the frame is addressed, or, if the MAC address table doesnt have a particular entry, the switch operates like a hub and sends the frame out to all devices except to the one sending the frame. 16, How is a wireless access point that is also a bridge more efficient in handling network traffic than a wireless access point that is not a bridge? Because the bridge limits the amount of traffic bet,even the two network segments. It allows only the traffic to pass that is destined for the other segment. 17.

To prevent crosstalk in a keystone RAJA jack, what is the minimum length of wire that should be untwisted? H inch Thinking critically 1. Linda has been assigned the job of connecting five computers to a network. The room holding the five computers has three network jacks that connect to a switch in an electrical closet down the hallway. Linda decides to install a second switch in the room. The new switch has tour network ports. She uses one port to connect the switch to a wall jack, Novo she has five ports available (two wall jacks and three switch ports). While installing and configuring the Nice in the five computers, she discovers that the PCs connected to the two wall jacks work fine, but the three connected to the switch refuse to communicate with the network. What could be wrong and what should she try next? Answer: Try connecting one of the non-working computers to a wall jack. If that works, then the problem is the switch, the cable connecting the switch to the wall jack, or the wall jack the switch is using. First try installing the switch on a known-good jack. Then replace the cable to the switch; then replace the switch. 2. If a Gigabit Ethernet NICE is having a problem communicating with a Bassett switch that only supports half duplex, what steps can you take to manually set the NICE to the speed and duplex used by the switch? Which speed and duplex should you choose? GO to Device Manager and Open the properties box for the NICE. Click the Link Speed tab and select 100 Mbps Half Duplex. 3. You connect a computer to an RI-AS wall jack using a straight-through cable. When you first open the browser on the computer, you discover it does not have Internet access. Order the following Steps in the correct order to troubleshoot the problem. A. Use a Lubbock plug to verify the network port on the computer. B. Rewire the keystone R]45 wall jack. C. Use a Lubbock plug to verify the network port in the wall jack. D. Exchange the straight-through cable for a known good one. E.

Definition and Examples of Vowels in English

Definition and Examples of Vowels in English Written English has a 26-letter alphabet. Of the 26, 20 are proper consonants, five are proper vowels, and one, the letter Y, can either be either a consonant or a vowel depending on usage. The proper vowels are A, E, I, O, and U. Coming from the Latin word for voice, vowels are the part of speech that is created by the relatively free passage of breath through the larynx and the mouth. When the mouth is obstructed during speech production- most often by the tongue or teeth- the resulting sound is a consonant. One Vowel, Many Pronunciations Vowels comprise the  principal sounds of syllables and form a major category of phonemes which are the distinct sets of sounds that allow a listener to distinguish one word from another  in speech.  Standard spoken English  has approximately 20 distinct vowel sounds, although regional dialectal variations account for more. As you can imagine, with each one potentially symbolizing multiple sounds on any written page, vowels letters are kept busy. How a vowel is pronounced in English depends very much on who is pronouncing it and where they hail from. There are currently as many as 160 distinct English-language dialects worldwide. For example, Standard American English has fewer vowel distinctions than Standard Southern British English, so while a Londoner from Mayfair would likely pronounce the words merry, marry, and Mary in three distinctly different ways, for the majority of Americans all three sound pretty much the same. With 29, England has the largest number of distinct dialects, and that doesnt even take dialects from Wales, Scotland, Northern Ireland, The Isle of Man, or the Channel Islands into account. The United States has 27 recorded dialects; India clocks in at 14 distinct dialects, followed closely by Ireland with 13, and Australia with 9. Long and Short Vowels In the English language, each of the vowels can be pronounced more than one way, but the two most common variations are long pronunciation and short pronunciation. These variations are often represented by typographical signs: a curved  symbol  above a vowel represents short pronunciation: ÄÆ', Ä•, Ä ­, Ã… , Ã… ­, while long  pronunciation  has by a horizontal line above the  vowel: Ä , Ä“, Ä «, Ã… , Ã… «. Vowels that have long pronunciations are most often modified by a secondary vowel thats generally silent. In words such as late or tune, the letter e is added to modify the main vowel sound, while in words such as goat or beat, the modifying vowel is the letter a, and in words such as night, knight, flight, and right, the long vowel i is modified by the letters gh. Fast Facts: Examples of Short and Long Vowel Pronunciation The Letter A- Short pronunciation: My hat sat on the mat. (hÄÆ't, sÄÆ't, mÄÆ't); Long Pronunciation: He ate the date on my plate. (Ä te, dÄ te, plÄ te)The Letter E- Short pronunciation: She let her pet get wet. (lÄ•t, pÄ•t, gÄ•t, wÄ•t); Long Pronunciation: His feet beat a neat retreat. (fÄ“et, bÄ“at, nÄ“at, rÄ“trÄ“at)The Letter I- Short pronunciation: Spit out that pit and I quit! (spÄ ­t, pÄ ­t, quÄ ­t); Long Pronunciation: The site of the bite from the mite was red. (sÄ «te, bÄ «te, mÄ «te.)The Letter O- Short pronunciation: That spot on the pots got rot. (spÃ… t, pÃ… t, gÃ… t, rÃ… t); Long Pronunciation: I wrote the quote on the note. (wrÃ… te, quÃ… te, nÃ… te)The Letter U- Short pronunciation: He cut the nut with a knife from his hut. (nut, cut, hut); Long Pronunciation: The mute on his lute was acute. (lÃ… «te, mÃ… «te, acÃ… «te) Vowel Pronunciation Rulebreakers While long and short are the most common vowel pronunciations, many words with vowel combinations do not follow these rules. For example, doubling the o in the word moon produces a long u (Ã… «) sound, while the y in duty not only modifies the u to an ew sound but rather than being silent, is pronounced as its own syllable with a long e (Ä“) sound. Words that must be pronounced on a case by case basis- such as aardvark, height, and diet- can be even more confusing for those first learning English. Using Phonetics to Pronounce Vowels Correctly As challenging as it may be to learn every correct vowel pronunciation with so many rules and exceptions, theres actually a fairly easy-to-learn system that can help to guide you. Phonetics is the branch of  linguistics  that deals with how  speech  is produced and offers a system of written symbols that represents each component sound in a language. Learning phonetics is an extra step in knowing how to pronounce words correctly but its not difficult and the results can be well worth the effort. In fact, actors often use phonetics to break words down into component sounds when they are required to speak in a dialect or accent that is not a reflection of their native voice.
