रिपीटर का मतलब क्या होता है? Network Repeaterया Repeater एक ऐसा powerful network device होता है जिनका इस्तमाल signals को regenerate करने के लिए होता है, जब वो लम्बी दुरी तय करते हैं, जिससे की signal की strength समान रहे.
Repeaters के विषय में एक बहुत ही महत्वपूर्ण बात यह हैं की repeaters signal को amplify नहीं करते हैं. जब signal weak बन जाते हैं, तब ये signal को copy करते हैं bit by bit और फिर उसे regenerate करते हैं उसके original strength में. यह एक 2 port deviceहोता है.
Repeaters का इस्तमाल Ethernet network को establish करने के लिए होता है. एक repeater OSI layer के first layer (physical layer) में स्तिथ होता है. Repeaters उन cables में इस्तमाल किया जाता है जिन्हें की करीब 100 meters तक की दूरता को cover करने के लिए होता है. इनका इस्तमाल signals पाने के लिए होता है optical fibers, copper cables और coaxial cables से.
Repeaters को develop बहुत से महत्वपूर्ण कार्य करने के लिए भी किया जा सकता है जैसे की microwave को regenerate करना एक satellite से; ऐसे repeaters को transponders कहा जाता है. इसलिए इन devices का उपयोग electric के साथ साथ light signals को carry करने के लिए भी होता है.
Repeater के Features क्या होते हैं?
एक repeater बहुत ही simplest facility होता है जिसका इस्तमाल network interconnection के लिए किया जाता है.
1. इसका major function होता है network signal को receive करना एक LAN terminal cable segment से और उन्हें regenerate करना और फिर उसी signal को retransmit करना उसकी original strength में एक या उससे ज्यादा cable segment में.
2. Basically repeater signal की strength को regenerate करती है उसे transmit करने से पहले.
3. Repeaters operate करते हैं OSI model के Physical layer में और ये transparent होते हैं सभी protocols को जो की operate होते हैं इसके ऊपर के layers में.
4. Repeaters allow करता है एक network को construct होने में जिससे की वो exceed हो सके एक single, physical, cable segment के size limit पर.
5. Repeater की संख्या कितनी होगी यह एक particular LAN implementation पर निर्भर करती है. एक repeater का इस्तमाल दो या उससे ज्यादा LAN cables segment में हो तब इसके लिए उन्हें समान physical layer protocol में कार्य करना होता है सभी cable segments में.
Repeaters का इस्तमाल Ethernet में
Repeaters का इस्तमाल बेहतर और efficient signal length प्राप्त करने के लिए होता है, इसलिए repeaters को ज्यादा Ethernet में उपयो किया जाता है.
Ethernet repeater का मुख्य कार्य होता है signal को carry करना एक Ethernet cable से दुसरे तक बिना कोई attenuation या signal strength के loss से.
वहीँ repeater system की मदद करते हैं किसी collision को detect करने में. अगर एक repeatKaise Plant Nursery Business Start kareer कोई collision को identify करता है, तब ये उस signal को सभी connected ports तक पहुंचाता है.
Repeater का इस्तमाल Ethernet के बहुत से segments को आपस में connect करने के लिए होता है. एक multiport repeater का ज्यादातर इस्तमाल इस चीज़ के लिए होता है. अगर दो host devices के बीच पांच से ज्यादा segments होंगे, तब ऐसे में अक्सर repeaters improper links को detect कर लेते हैं; ऐसे में data flow terminate हो जाता है तब तक के लिए जब जाट की data सही तरीके से accurate या rectify न हो जाये.Kya Hota Hai Drone How to Work it
Repeaters smart devices होते हैं; वो signals को regulate करते हैं और signal flow को control भी करते हैं. जिससे की wires को बचाया जा सके damage या breakage से.Business start of the brick manufacturer in Hindi
Repeaters network segments की continuous working को भी enable करता है, अगर कोई segment टूट जाये या वो कोई function करने में असक्षम हो जाये. इसलिए repeaters बहुत ही ज्यादा helpful होते हैं wired networks के smooth functioning में.Petroleum Jelly Production of Hindi & English in full detail
वाईफाई रिपीटर क्या है और कैसे काम करते हैं?
Wireless routers के तरह ही, अब market में wireless repeaters भी उपलब्ध हैं. Wireless repeaters का इस्तमाल wireless signals के range को बढ़ाने के लिए होता है, इसमें और wires या devices को embed करने के कोई भी जरुरत नहीं होती है. यदि आपको एक instant और efficient boost की जरुरत है आपके deteriorating signal strength में, तब आपको एक wireless repeater को आपके computer और WAP के बिच में स्थापित करना होगा.
यदि हम इनकी काम करने की प्रक्रिया को समझें तब Wireless repeaters radio signals को receive करते हैं एक WAP से और उन्हें regenerate करते हैं फिर उन्हें deliver करते हैं frames के form में. Wireless repeaters का इस्तमाल एक operator को offer करता है sufficient convenience जिससे की वो wireless repeater का इस्तमाल कर सकता है ज्यादा access points को add करने की जगह में.Solar light Consumption and Energy Savings
ये repeaters wireless system के एक बहुत ही major weakness को overcome करने में मदद कर सकते हैं. ये major weakness है signal attenuation (signal का कमजोर होना). Wireless repeaters बहुत ही ज्यादा capable होते हैं wireless signal के coverage को बढ़ाने में.
जब एक repeater को place किया जाता है एक remote location में, जहाँ की network signals travel तो कर सकती है, लेकिन बहुत ही ज्यादा weak हो जाती है. इन जगहों में connectivity बढ़ जाती है इन repeaters के इस्तमाल से. उदहरण के लिए अगर एक आदमी travel करता है अपने research project के लिए, तब वो अपने साथ एक wireless repeater carry कर सकता है; जिससे की वो signals regenerate कर सकता है repeater के इस्तमाल से. इससे उसके सभी communication gapes को आसानी से makeup किया जा सकता है और उसे बिना रुकावट के signals मिल सकती हैं.
Star Topology में Repeaters का इस्तमाल
एक LAN में जब प्रत्येक individual unit को एक access प्रदान किया जाता है directly communicate करने के लिए central device या hub से, तब इसे star topology कहा जाता है. Topology की परिभाषा को समझें तब यह एक physical set up होता है जिससे की एक network connection point को establish किया जा सके. इसमें इस central device को कहा जाता है एक multiport repeater. इस repeater का मुख्य purpose होता है की ये allow करें signal को लम्बी दुरी तय करने के लिए. Multiple ports Ethernet repeaters का इस्तमाल star topology cabling के deficiency (दुर्बलता) को कम करने के लिए होता है.
रिपीटर का कार्य
Digital communication systems में, एक repeater ऐसा device होता है जो की digital signal को receive करते हैं एक electromagnetic या optical transmission medium में और फिर उसे regenerate करते हैं उस signal को अगले medium में.
Electromagnetic media में, repeaters attenuation की समस्या को दूर करते हैं जो की free-space electromagnetic-field divergence या cable loss से उत्पन्न होता है. Repeaters के एक series के इस्तमाल से ये signal की extension होने में मदद करता है लम्बी दूरता तय करने के लिए.
1) Repeaters हटाता है unwanted noise को एक incoming signal से. एक analog signal के विपरीत, original digital signal को और एक बार restore किया जा सकता है चाहे तो कितना भी weak या distorted क्यूँ न हो. Analog transmission में, signals को restrengthened किया जाता है amplifiers से लेकिन इससे noise और information भी amplify हो जाती है.
चूँकि digital signals निर्भर करता है voltage के होने या न होने से, इसलिए वो जल्द ही dissipate हो जाते हैं analog signals की तुलना में इसलिए उन्हें ज्यादा frequent repeating की जरुरत होती है. इसलिए analog signal amplifiers को 18,000 meter intervals की दूरता में लगाया जाता है, वहीँ digital signal repeaters को typically place किया जाता है 2,000 से 6,000 meter की intervals में.
2) एक wireless communications system के, एक repeater में ये चीज़ें होती हैं radio receiver, एक amplifier, एक transmitter, एक isolator, और दो antennas. इसमें transmitter ऐसी signal produce करती है जिसकी frequency भिन्न होती है received signal से. यही frequency offset ही बहुत ही जरुरी होता है strong transmitted signal को दूर रखने के लिए उसे receiver को disable करने से. ऐसे में isolator एक additional protection प्रदान करता है.
वहीँ एक repeater, जिसे की strategically ही locate किया गया होता है high building या किसी पहाड़ के top में, और ये बहुत हद तक wireless network के performance को बढ़ा सकता है जिससे की लम्बी दूरता के लिए आसानी से communication किया जा सके.
3) इन satellite wireless में, एक repeater (जिसे की frequently एक transponder भी कहा जाता है) receive करता है uplink signals और उसे फिर retransmits करता है, अक्सर अलग अलग frequencies में, दुसरे locations को.
4) इन्हें cellular telephone system में भी इस्तमाल किया जाता है, एक repeater एक प्रकार का group होता हिया transceivers का, एक geographic area का जो की collectively ही serve करता है एक system user को.
5) वहीँ एक fiber optic network में, एक repeater में एक photocell, एक amplifier, और एक light-emitting diode (LED) या infrared-emitting diode (IRED) होते हैं प्रत्येक light या IR signal के लिए जिन्हें की amplification की जरुरत होती है. Fiber optic repeaters operate करते हैं बहुत ही कम power levels में यदि हम इनकी तुलना करें wireless repeaters से, और ये बहुत ही ज्यादा simpler और cheaper भी होते हैं. लेकिन इन्हें बनाते वक़्त इस बात को जरुर से ध्यान देना चाहिए की इनकी internal circuit noise को हमेशा minimized किया जाये.
6) Repeaters को commonly इस्तमाल किया जाता है commercial और amateur radio operators के द्वारा जिससे की signals को radio frequency range में extend किया जा सके एक receiver से दुसरे तक. इनमें drop repeaters होते हैं, जो की cells किसी cellular radio के तरह होते हैं, और hub repeaters, जो signals को receive कर उन्हें retransmit भी करते हैं बहुत से directions में.
7) एक bus repeater link करता है एक computer bus को दुसरे bus के साथ जो की दुसरे computer chassis में होता है, जिससे की एक computer से दुसरे computer की chaining की जा सके.
Repeater के Advantages क्या होते है?
1. Connect करना Simple होता है
इन्हें connect करना बहुत ही आसानी से किया जा सकता है. साथ ही खोलना भी.
2. Cost effective
ये ज्यादा costly भी नहीं होते हैं बाकि के network components के जैसे इसलिए ये ज्यादा cost effective होते हैं.
3. इनकी Ability की signal की strength को बढ़ाये
Repeater या Wireless repeater की एक बहुत ही primary advantage यह है की यह wireless signal strength को बढ़ाने में मदद करती है. ये तो आपको पता ही हो गा की जितनी दूरता में computer स्तिथ होगा wireless router से उतनी ही weak होगी wireless signal. ऐसे में यदि एक wireless repeater को place कर दिया जाये computer और router के बिच में तब signal की strength को काफी बढाया जा सकता है.
I reckon something genuinely special in this site.
thanks for appreciate my work
Hi there, I found your website via Google while searching for a related topic, your web site came up, it looks good. I have bookmarked it in my google bookmarks.
Hey, how’s it going?
I want to pass along some very important news that everyone needs to hear!
In December of 2017, Donald Trump made history by recognizing Jerusalem as the capital of Israel. Why is this big news? Because by this the Jewish people of Israel are now able to press forward in bringing about the Third Temple prophesied in the Bible.
Jewish Rabbis have publicly announced that their Messiah will be revealed in the coming years who will be a leader and spiritual guide to all nations, gathering all religions under the worship of one God.
Biblical prophecy tells us that this Jewish Messiah who will take the stage will be the antichrist “who opposes and exalts himself above all that is called God or that is worshiped, so that he sits as God in the temple of God, showing himself that he is God” (2 Thessalonians 2:4). For a time he will bring about a false peace, but “Therefore when you see the ‘abomination of desolation,’ spoken of by Daniel the prophet, standing in the holy place (Matthew 24:15)…then there will be great tribulation, such as has not been since the beginning of the world until this time, no, nor ever shall be” (Matthew 24:21).
More importantly, the power that runs the world wants to put a RFID microchip in our body making us total slaves to them. This chip matches perfectly with the Mark of the Beast in the Bible, more specifically in Revelation 13:16-18:
“He causes all, both small and great, rich and poor, free and slave, to receive a mark on their right hand or on their foreheads, and that no one may buy or sell except one who has the mark or the name of the beast, or the number of his name.
Here is wisdom. Let him who has understanding calculate the number of the beast, for it is the number of a man: His number is 666.”
Referring to the last days, this could only be speaking of a cashless society, which we have yet to see, but are heading towards. Otherwise, we could still buy or sell without the mark amongst others if physical money was still currency. This Mark couldn’t be spiritual because the word references two different physical locations. If it was spiritual it would just say in the forehead. RFID microchip implant technology will be the future of a one world cashless society containing digital currency. It will be implanted in the right-hand or the forehead, and we cannot buy or sell without it. Revelation 13:11-18 tells us that a false prophet will arise on the world scene doing miracles before men, deceiving them to receive this Mark. Do not be deceived! We must grow strong in Jesus. AT ALL COSTS, DO NOT TAKE IT!
“Then a third angel followed them, saying with a loud voice, “If anyone worships the beast and his image, and receives his mark on his forehead or on his hand, he himself shall also drink of the wine of the wrath of God, which is poured out full strength into the cup of His indignation. He shall be tormented with fire and brimstone in the presence of the holy angels and in the presence of the Lamb. And the smoke of their torment ascends forever and ever; and they have no rest day or night, who worship the beast and his image, and whoever receives the mark of his name” (Revelation 14:9-11).
People have been saying the end is coming for many years, but we needed two key things. One, the Third Temple, and two, the technology for a cashless society to fulfill the prophecy of the Mark of the Beast.
Visit http://WWW.BIBLEFREEDOM.COM to see proof for these things and why the Bible truly is the word of God!
If you haven’t already, it is time to seek God with all your heart. Jesus loves you more than you could imagine. He wants to have a relationship with you and redeem you from your sins. Turn to Him and repent while there is still hope! This is forever…God bless!
“EITHER HUMAN INTELLIGENCE ULTIMATELY OWES ITS ORIGIN TO MINDLESS MATTER OR THERE IS A CREATOR…” – JOHN LENNOX
We all know God exists. Why? Because without Him, we couldn’t prove anything at all. Do we live our lives as if we cannot know anything? No. So why is God necessary? In order to know anything for certain, you would have to know everything, or have revelation from somebody who does. Who is capable of knowing everything? God. So to know anything, you would have to be God, or know God.
A worldview without God cannot account for the uniformity and intelligibility of nature. And why is it that we can even reason that God is the best explanation for this if there is no God? We are given reason to know or reject God, but never to know that He does not exist.
It has been calculated by Roger Penrose that the odds of the initial conditions for the big bang to produce the universe that we see to be a number so big, that we could put a zero on every particle in the universe, and even that would not be enough to use every zero. What are the odds that God created the universe? Odds are no such thing. Who of you would gamble your life on one coin flip?
Is there evidence that the Bible is the truth? Yes. Did you know that the creation accounts listed in the book of Genesis are not only all correct, but are also in the correct chronological order? That the Bible doesn’t say the Earth was formed in six 24-hour days but rather six long but finite periods of time? That the Bible makes 10 times more creation claims than all major “holy” books combined with no contradictions, while these other books have errors in them? The Bible stood alone by concurring with the big bang saying, “In the beginning God created the heaven and the earth” (Genesis 1:1); and says our universe is expanding, thousands of years before scientists discovered these things. Watch a potential life-changing video on the website listed below with Astronomer(PhD) Hugh Ross explaining all these facts based on published scientific data. He has authored many books, backed even by atheist scientists.
Jesus came to pay a debt that we could not; to be our legal justifier to reconcile us back to a Holy God; only if we are willing to receive Him: “For the wages of sin is death…” (Romans 6:23).
God so loved the world that He gave us His only begotten son, so that whoever believes in Him, through faith, shall not perish, but have everlasting life. Jesus says if we wish to enter into life to keep the commands! The two greatest commands are to love God with all your heart, soul, strength, and mind; and your neighbor as yourself. All the law hang on these commands. We must be born of and lead by the Holy Spirit, to be called children of God, to inherit the kingdom. If we are willing to humble ourselves in prayer to Jesus, to confess and forsake our sins, He is willing to give the Holy Spirit to those who keep asking of Him; giving us a new heart, leading us into all truth!
Jesus came to free us from the bondage of sin. The everlasting fire was prepared for the devil and his angels due to disobedience to God’s law. If we do the same, what makes us any different than the devil? Jesus says unless we repent, we shall perish. For sin is the transgression of the law. We must walk in the Spirit so we may not fulfill the lusts of the flesh, being hatred, fornication, drunkenness and the like. Whoever practices such things will not inherit the kingdom (Galatians 5:16-26). If we sin, we may come before Jesus to ask for forgiveness (1 John 2:1-2). Evil thoughts are not sins, but rather temptations. It is not until these thoughts conceive and give birth by our own desires that they become sin (James 1:12-15). When we sin, we become in the likeness of the devil’s image, for he who sins is of the devil (1 John 3:8); but if we obey Jesus, in the image of God. For without holiness, we shall not see the Lord (Hebrews 12:14).
The oldest religion in the world is holiness through faith (James 1:27). What religion did Adam and Eve follow before the fall? Jesus, Who became the last Adam, what religion does He follow? Is He not holy? He never told us to follow the rituals and traditions of man but to take up our cross and follow Him (Luke 9:23). There are many false doctrines being taught leading people astray. This is why we need the Holy Spirit for discernment. Unlike religion, holiness cannot be created. It is given to us from above by the baptism of the Spirit. Jesus is more than a religion; He is about having a personal relationship with the Father. Start by reading the Gospel of Matthew, to hear the words of God, to know His character and commandments. Follow and obey Jesus, for He is the way, the truth, and the life!

The most effective way to shed weight is by getting it bit by bit and using some basic ideas which can assist you to make the most out of your attempt to lose weight. You may recognize and already be following some of these tips, yet reinforcing knowledge never does any damage.
Please let me know if you’re looking for a writer for your site. You have some really great posts and I think I would be a good asset. If you ever want to take some of the load off, I’d really like to write some content for your blog in exchange for a link back to mine. Please send me an email if interested. Thanks!
Thanks for expressing your ideas. I would also like to express that video games have been ever before evolving. Modern tools and enhancements have helped create reasonable and active games. These types of entertainment games were not actually sensible when the real concept was first being tried. Just like other designs of electronics, video games as well have had to develop through many decades. This is testimony on the fast growth of video games.
A further issue is that video gaming became one of the all-time greatest forms of excitement for people spanning various ages. Kids enjoy video games, and adults do, too. The XBox 360 has become the favorite games systems for many who love to have a huge variety of video games available to them, in addition to who like to learn live with people all over the world. Many thanks for sharing your thinking.
