ARE FACEBOOK USERS MORE OR LESS LONELY? Nowadays, teenagers have become addicted to numerous social networks and cannot live a day without getting online. This, of course, influences the formation of their individuality. Every one of Facebook users develops certain feelings while using the website. The two most related qualities are self-esteem and loneliness. I think Facebook is not a real problem for problem , its just for fun or to make new friends or to keep in touch with your friends/relatives who live far away from you. I agree that in some cases people get addicted to facebook , I was once too. I used to stay all day in facebook . but now I don’t , I hardly ever use it . when I didn’t have with who to talk , I felt lonely . I only stayed in my room waiting for someone to text me .Now I just to enjoy life with my friends near me , not imaginary friends, who sometimes can be lying for different things . so using social networ...

New Media Economy Social media information and data collection and security In this brief essay, i would like to focus on the social media platforms in our moren society. How people use them, what kind of information we give away, what companies will do with this. Information sharing and data protection has become very popular theme in the recent few years. People care more about their privacy and avoid „big brother“ foreshadowing. It is important to know what social media platforms promise and are they really going to keep it. Users should think about what they share and what kind of information they generate. Because it is all recorded and some info can be traced back to real people. Privacy and data protecion topics are becoming more and more important and the amouts of data generated is becoming larger. When wrongly access this kind of data, a lot damage could be done by criminals. Users privacy settings should be reviewd and ...
Sissejuhatus Kommunikatsioon ehk suhtlemine ümbritseb meid igapäevaselt ning areneb ja muutub koos meiega. Tänapäeva globaliseeruvas maailmas on üha tähtsam roll inimestevahelisel suhtlusel sotsiaalmeedias. Kuidas mõjutab Facebook meie isiksuseomadusi? Kuidas erineb identiteet päriselus ja internetis? Üritan leida vastust nendele küsimustele tuginedes suhtlemispsühholoogiale ja erinevatele läbiviidud uuringutele. Statistikaameti andmetele tuginedes on 2013.aastal 80,6% Eesti leibkondadest kodus Internetiühendus (Statistikaamet,2013,/5/). Internetisuhtlus on muutunud samaoluliseks kui teised suhtlemisviisid. Kas võime seda võrdsustada tavalise näost-näkku suhtlemisega? Facebooki mõju isiksuseomadustele Viimase kuue aasta jooksul on saanud Facebookist üks kiiremini arenev internetikeskkond. Oktoobris 2012 raporteeris Facebook, et seda saiti kasutab kuus keskmiselt miljard inimest. (Facebook, 2012,/2/) Facebo...
Facebook is a social networking service, which was launched in February 2004. It is owned and operated by Facebook Inc. In September 2012 Facebook had over billion active users and more than half of them were also using Facebook on a mobile device. Facebook's latest research shows that the most popular mobile device used for visiting m.facebook.com is iOS and by the popularity the second most used device is Android. Using Facebook on your mobile device raises the potential of your account getting stealed. It is so because most of the users don't use safe connection so all your data is available to other users on the same network. So the very first thing you should do is to use safe connection by adding to the end of this word ,,http://" (which you can find in the beginning of every webpage) an ,,s" so the address should be like ,,https://". The second thing you can do is that if you own the Wi-Fi access point then you should definately...
Advatanges and disadvantages of using facebook Facebook is a social page of internet. It´s the most popular community website at the moment, in the world.

First of all, I'd like to ask how many of you visit Facebook on daily basis?... I thought so! Nowadays it would be hard to find a person who hasn't heard of Facebook. One in every 13 people on Earth is on Facebook right now. It is equal to oxygen for millions and millions of people. It currently has 800 million members and the numbers are going up as we speak. It would be fascinating to know, what caused such kind of phenomenon. At present I believe I could say that life has gathered into the Facebook. We can track in real time what people are doing, who they are communicating, what their marital status is and what mood they're in. Even businesses are promoting and seeking for new potential customers- through different public games where you can win from fancy dinners to fully paid trips to Hawaii. And it has been made so simple- you only have to click like and share. I think that Facebook is a good way to boost one's ego. I see people ...
Are IT and communication technology bringing about more positive or negative changes? Dear audience, i want to tell you about the positive and negative sides of it and communication technology. Informational technology is most commonly used to talk about computers and computer networks but it also includes other information sorces such as television and telephones. Electronic computers began to appear in the early 1940's. The origins of the internet are from the 1960's. Over a third of the human's population have used the services of the internet. But what about the other two thirds? Is is better for them to have not been able to use this huge network, or is it a bad thing? The first biggest concerns are the communication sites because they are used too often and they tend to change the view how we understand the term ,,personal relationships". The most popular social network-Facebook-was launched in 2004 and it has beco...
Oskar Lutsu Palamuse Gümnaasium Margit Orma 11. klass SOTSIAALMEEDIAS POSTITUSTE LEVIMINE JA SELLE MÕJU Uurimistöö Juhendaja: Marjo Toomik Palamuse 2017 SISUKORD SISSEJUHATUS Minu teemaks on sotsiaalmeedias postituste levimine ja selle mõju. Teema valimisel mängisid suurt rooli noormehed Taanist. Nende postitust nähes tulin ideele neid järgida (vt. Lisa 1). Teema valimisel sai määravaks see, et olen ise sotsiaalmeedia kasutaja ning soovisin teada saada, kuidas levivad ning mõjuvad postitused. Uurimistöös kasutatud uurimismeetodiks on tegevusuurimus. Töös on kolm peatükki ja kolmteist alapeatükki. Töö teoreetilises osas uurisin sotsiaalmeedia liike ning kanaleid. Praktilise osa tarbeks postitasin sotsiaalmeediasse Facebook ühe pildi ja ühe video. Pildil ning videos palusin inim...
Programmeerimine keeles PHP Andrei Porõvkin Tartu Ülikool (2009) 1 1.1 Üldinfo Alguses oli interneti lehed omavahel seotud staatiliste html dokumentide süsteemina, aga selleks, et mingis dokumendis muutusi teha oli vaja lehti failisüsteemis käsitsi muuta. Kahjuks selline staatiline mudel ei jõua kiirelt muutuva kaasaegse maailma progressile järgi. Seega võeti kasutusele dünaamiline mudel. Dünaamilise mudeli korral ei hoita serveris staatilisi html lehte vaid neid genereeritakse selleks spetsiaalselt välja töötatud programmidega, mis serveril töötavad. Antud kursuse jooksul tutvume klient-server arhitektuuriga, installeerime enda arvutisse veebiserveri ja php interpretaatori ning saame baasteadmisi serveripoolsest keelest PHP. Kursuse teemad on pühendatud ainult PHP keelele (väljarvatud seitsmes teema), aga see ei tähenda, et sellest piisab suure ja eduka veebilehe loomiseks. Mahuka infosüsteemi e...

E-turunduse ja e-kaubanduse alused 2016, kordamisküsimused 1. Kas Internetiturundus ja e-turundus on üks ja seesama? Kui jah, siis kuidas, kui ei, siis miks. E-turundust peetakse laiemaks mõisteks kui Internetiturundust. Viimane tähendab kitsalt just Internetile (veeb, elektronpost) orienteeritud meetmeid. Internetiturunduse puhul on kasutatavaks meediumiks Internet. E-turundus aga hõlmab lisaks ka mobiilse ja muu traadita meediumi kasutamist ning digitaalset kliendiandmete haldamist ja kliendisuhete juhtimist. Digitaalne keskkond ei koosne enam ammu ainult klassikalistest veebirakendustest ja elektronpostipõhisest kommunikatsioonist. Lisandunud on mitmesugused mobiilsed personaliseerimise (NFC, QR-koodid) tehnoloogiad ning asukohapõhised (GPS) teenused. Nende puhul on Internet käsitletav vaid puhtalt andmevahetuskanalite komplektina, turundustegevus ise toimub kommunikatsioonimudeli järgmisel, kõrgemal kihil. Seetõttu on mõistlik...
Strateegiline juhtimine Kordamisküsimused 1. Strateegia. x Strateegia on firma otsustusloogika. (Kreitner) x Strateegia kujutab endast teatud hulka hüpoteese põhjuste ja tagajärgede seoste kohta. (Kaplan, Norton) x Strateegia on org.-i eesmärkide ja ressursside ning muutuvate turundusvõimaluste ühildamine. (Kotler) x Strateegia ilma taktikata on kõige aeglasem tee võiduni. Taktika ilma strateegiata on ainult ettevalmistus alistumiseks. (Sun Tzu c. 500 BC) Leimann väidab, et strateegia kujutab endast pikaajaliste eesmärkide saavutamise põhiteede ja tegevuspõhimõtete kogumit, mis on organisatsiooni arengu juhtimise aluseks. Organisatsiooni strateegia hõlmab organisatsiooni kõiki olulisi funktsioone ja allüksusi ja ta peaks tagama, et organisatsioonis langetatavad otsused on omavahel kooskõlas. Strateegia kavandamine ja elluviimine on juhtimise olu...
