Acessi andmebaas on konteinerfail,mis võib sisaldada järgmist tüüpi objekte: tabelid, päringud,vormid aruanded, makrod ja programmimoodulid. Tabelid (tables) on igasuguse andmebaasi vundament, kõik ülejäänu on ainult pealisehitus- Tabeleid "teenindavad organid", et nendesse võimalikult mugavalt andmeid sisestada ja neist kätte saada. Päringud(queries) on eeskiri,mis määrab, millistest tabelitest missuguseid (näiteks teatud tingimustele vastavaid) andmeid on vaja esitada. Seega, päringu väljund on omakorda tabel, kuid juba tuletatud tabel, mitte fundamentaalne, ning seetõttu ei kuulu tabelite rubriiki. Vormid(forms) on dialoogikastid, milles olevatye kontrollelementide (nt. Tekstkast või nupp) abil saab tabelite andmeid mugavalt esitada ja muuta. Aruandeks(reports) nimetatakse tabelites esinevate andmete esitust dokumendi kujul, mis on väga hea igasuguste kokkuvõtete ja ülevaadete tegemiseks. Makroks(macros) nimetatakse käskude jada. Se...

See andmebaas on koostatud selleks, et videolaenutuses olevatel töötajatel oleks võimalikult lihtne leida üles millised inimesed on kasutanud laenutamiseteenust, milliseid kassette nad on laenutanud. Andmebaasist on lihtne leida millisel kuupäeval peavad inimesed laenutatud kassetid tagastama ja kui suur on hilinemisel nende viivis. Juhul kui inimesed tahavad filmide kohta teada saada veel lisainfot, siis tabelites on koostatud erinevaid päringuid ja v...
1. andmebaasi loomise aeg; Open Access (http://www.doaj.org) Open Access ehk avatud juurdepääs on andmebaas, mis tagab piiranguteta ja tasuta juurdepääsu teadusinformatsioonile internetis. Avatud juurdepääsu oluline külg on selle kiire levik üle kogu maailma. (http://www.utlib.ee/index.php?e_id=367) Andmebaasi loomise alguseks loetakse 1990-ndaid aastaid. (http://www.plosone.org/article/info:doi/10.1371/journal.pone.0020961) Aastal 2003 oli loodud ajakirjade register. (https://moodle.e- ope.ee/mod/resource/view.php?id=307428), Projekti eesmärgiks oli koguda elektrooniliste teadusajakirjade ja tagada vaba juurdepääsu tasuta teadlaskonna liikmetele. (http://infocenter.nlr.ru/databases/science/?item_id=553) Idee luua kataloog avatud juurdepääsuga kiideti heaks ainult aastal 2002 Esimese Põhjamaade konverentsil Lundis (Rootsi) ja Kopenhaagenis (Taani).

EUTHANASIA Many hotly debated social questions revolve around choice. Giving people access to assistance in dying is one of them. The issue is too sensitive to come to a smple conclusion. The basic question is : should a person who is terminally ill and who feels that their life is not worth living, who is repeatedly asking for euthanasia and who is of sound mind be given assistance in dying so that they could do it in a dignified manner rather than have their lives prolonged by medical technology? Ultimately, it's a question of choice: empowering people to have control over their own bodies. The main opposition comes from religious groups, medical associations whose members see practising euthanasia as an inproper exctension of their role as carers. Throughout centuries the doctors' purpose in life has been to cure suffering, how can they be expected to do otherwise, even if it's done for...

OSI 7-kihilise arhitektuuriga baasmudel annab loogilise struktuuri konkreetsetele andmesidevõrkude standarditele. Tegelikus elus on andmesidevõrkudes kasutusel terve rida erinevaid protokollistikke (TCP/IP, NetWare, AppleTalk, DECnet, ATM, SNA ja SS7 jne.), mis ei vasta täpselt OSI mudelile (näit. on paar OSI kihti ühendatud üheks kihiks vms), kuid põhimõtteliselt täidavad need kõik ühtesid ja samu funktsioone ning OSI mudel on heaks õppevahendiks ka teiste protokollistike tundmaõppimisel. 1982.a. said ISO ja ITU-T valmis ka OSI protokollistandardid, kuid esiteks oleks nende k...

Modern issues It's 21st century, and we still have many issues, that need to be solved. Of course we can't solve all the problems. It is impossible, but at least we should give our best to try to solve these important modern issues. One of the biggest issues is access to clean water. 1st and 2nd world countries may not or don't have that problem at all, but access to a clean water is a serious issue for 3rd world countries. 3rd world countries might have an access to water, but not to clean water. It is important to have a clean water, because there are a lot of dangerous diseases in dirty water. It's a problem, which needs to be solved as quickly as possible. Another problem is an access to good food. About 21,000 people die every day of hunger, or hunger-related causes. This is one person every four seconds. Most of them are children. We already grow enough food for 10 billion people, so the...

Social Problems Crime In the sociological field, crime is the breach of a rule or law for which some governing authority or force may ultimately prescribe a punishment. The word crime originates from the Latin crimen. When society deems informal relationships and sanctions insufficient to create and maintain a desired social order, there may result more formalized systems of social control imposed by a government, or more broadly, by a State. With the institutional and legal machinery at their disposal, agents of the State can compel individuals to conform to behavioural codes and punish those that do not. Various mechanisms are employed to regulate behaviour, including rules codified into laws, policing people to ensure they comply with those laws, and other policies and practices designed to prevent crime. In addition are remedies and sanctions, and collectively these constitute a crimi...

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...

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 ...

Attraction of blogs People have always loved to share their thoughts. It is very common that people write those thoughts down, usually into their secret diaries. Nowadays individuals write public blogs, which using has grown quite popular. In my opinion, blogs have become more fashionable than keeping private diaries, because they are public. Everyone has access and a chance to read your own personal views. We live in a modern world, where information is crucial and selling, therefore keeping a blog on the Internet is a big attraction for readers. Furthermore, there are all kinds of journals on the web, for example food sites, where people can find many recipes for different meals. Also, fashion blogs, which can give inspiration if wondering what to wear for some kind of an occasion. Not only are the blogs entertaining, they can also be very helpful and useful.

The computer has greatly improved our lives today Nowadays, computers are a big part of our lives and they have made pretty much everything simpler and more entertaining. On the other hand, the misuse of them can be extremely dangerous. On the positive side, computers are great tools for school and different jobs. Using the Internet it is possible to communicate with each other and access to information faster. Another advantage is that almost the whole world has access to those technological inventions, so if someone lives in Australia, it is surprisingly easy for them to find a friend from Europe. On the negative side, there are lots of hackers who can damage big companies or leak personal information. In addition to this, people spend too much time in front of computer screens and that causes visual illness, sickness, stress, muscular pains, etc. Furthermore, there is a lot of trash on the Internet, f...
What is needed for good society Good society needs three things. These things are: rudimentary democratic consent, universal access to human essentials and accessibility to other desirable items. If these aspects are not fulfilled; it is not a good society. In my opinion, good society is not the thing what suits for everybody, because if you will not agree with good society standards, you really are not the person who would be advantageous for this kind of society. Person who is not accepting these standards is communist and only fits in to the dictatorship supportive countries. For being appropriate member for food society you have to accept other people needs and at the same time sacrifice some of your own needs. Good society is not a paradise. Universal access to human essentials means that everyone have the rights to access elementary things for living, such as: air, water, food, protection from harsh...

RAM Sissejuhatus: RAM- Random Access Memory. Suvapöördusmälu eesti keeles. Tegemist on mäluga, millele saab andmeid kirjutada ja andmeid lugeda sama kiirusega olenemata kus mälukiibil ja mis asukohal andmed asuvad. Tänapäeval leiame me RAM-i mikrokiipide kujul. Tegemist on hävimäluga, mis tähendab, et hoiustatud andmed kaovad mälust, kui kaob voolutoide. Vastandiks on näiteks ROM, Read Only Memory, milles säilivad andmed ka peale voolu kadumist. Kaks RAMi tüüpi: RAMi jaotatakse tänapäeval kaheks. Nendeks on SRAM ja DRAM. Esimene on neist Staatiline teine dünaamiline. SRAM-de puhul salvestatakse 1 bit kasutades kuute transistori. Sellist tüüpi RAM-i on kallim toota kuid ta on kiirem ja tarbib vähem voolu kui DRAM. Teda kasutatakse põhiliselt vahemäludes protsessorites oma kiiruse tõttu. DRAM mälude puhul salvestatakse üks bit kasutades transistori ja kondensaatori paari. Kondensaator hoiab kas ...

For and Against Mobile Phones Mobile phones have become a essential part of people's lives. Almost everybody has a mobile phone. This essay will deal advantages and disadvantages of using mobile phones. Nowadays mobile phones have internet. It is very useful and it guarantees a quick access to the information one need. Furthermore, why mobile phones are important is that one can call help. For example when there has been an accident , one can call quickly the ambulance. Also mobile phones are very handy because one can use it almost everywhere. Whether one is in a forest or in a big city, one can call or use the internet. But mobile phones have their downsides too. Firstly, buying a good mobile phone which has internet access, GPS and other useful applications is quite expensive. Secondly, mobile phones have made people lazy. Hardly no-one goes to knock on a door to ask a friend out. Instead they call or s...
SDRAM Sünkroonne dünaamiline muutmälu ehk SDRAM (inglise Synchronous Dynamic Random Access Memory) on dünaamiline muutmälu (DRAM), mida sünkroniseeritakse süsteemisiiniga. Klassikalisel DRAM-il on asünkroonne liides, mis vastab nii kiiresti kui võimalik igasugustele muutustele juhtsisendites. Erinevalt DRAM-is on SDRAM-il aga sünkroonne liides, mis tähendab seda, et ta ootab taktsignaali ära enne, kui vastab juhtsisenditele. Takti kasutatakse selleks, et juhtida sisemist lõplikku olekumasinat (Finite State Machine ehk FSP), mis omakorda võtab vastu sissetulevaid käske (käsukonveierid). See annab kiibile võimaluse teha palju keerulisemaid operatsioonijuppe, mis soodustab kiiremat tööd. RDRAM RDRAM (Rambus DRAM) – Valmistatud Rambus Inc. Poolt 1990-ndatel DIMM SDRAM'i asenduseks. Seda tüüpi RAM'i võib leida ka kolmes mängukonsoolis: Nintendo 64, Playstation 2 ja Playstation 3 (XDR DRAM). RAM Muutmälu ehk RAM (lühend ingliskeelsetest ...
1. Kihiline arhitektuur: kuidas see tekib ja milleks see hea on? 3-kihiline mudel: *rakendused, *arvutid, *võrk. Kihtide vaheline suhtlemine toimub läbi SAP-punktide (Service Access Point). Selle 3-kihilisele mudelile oleks vaja 2 tasemelist aadressi: *jaama aadress (network address) ja rakenduste poole pöördumise aadress (SAP address). Sõnum liiga pikk , siis transpordikiht jaotab selle väiksemateks tükkideks ning paneb igale tükile päise (header) juurde. Saadakse andmeüksus PDU (Protocol Data Unit). OSI raammudel(1984) jagab keerulise arvutitevahelise infovahetuse probleemi seitsmeks väiksemaks, iseseisvamaks ja lihtsamini käsitletavaks probleemiks. Igale seitsmest probleemist vastab mudelis üks kiht. OSI kirjeldab, kuidas informatsioon leiab tee rakendusprogrammist võrgumeediumi kaudu teise rakendusprogrammi teises hostis. 2. OSI mudeli üldmõisted: kihid, teenused, protokollid. OSI-mud koosneb seitsmest kihist. Naaberkih...

The best way of educating yourself is using the Internet In the last decades, internet has developed tremendously. Nowadays Almost every person on Earth has access to the Internet. Internet is becoming a basic human right and use of the computers is expanding more and more, hence the usage of internet. Internet also has a great value for schools, because learning by using the Internet has many advantages on other ways of learning. But what makes Internet so good to be used for learning? Internet is constantly evolving, making it the most reliable and up-to-date source of information. Books are getting older and the information is expiring, but the Internet is evolving with time. In the Internet, expired information is replaced with new. It is easier to find what you need to learn. For example, using books or other data carriers on paper, you are forced just to read, read and read. Using the Internet, you can find whatever you need to...

Wi-Fi Wi-Fi Wi-Fi Wireless Fidelity on võrk mille abil jagatakse tavaliselt Interneti teenust. Kohtvõrguna on ta mõeldud ühes ruumis suure hulga arvutite teenindamiseks. Wi-Fi kasutab andmeedastuseks sagedust 2,4Ghz. Edastuskiirus on 11Mbit/s või ka 22 ja 54Mbit/s. Wi-Fi 2 Wi-Fi maksimum edastuskaugus kohtvõrgus on umbes 100 meetrit. Ühendus on sellisel juhul piiratud kiirusega ja seda saab kasutada väga lühikese maa tagant. Kiirust ja kvaliteeti segavad palju ka välised mõjutajad Wi-Fi 3 Wi-Fi ühenduse saamiseks peab olema access point, mis pakub seda ühendust ja arvutis vastav kaart, mis suudab suhelda Wi-Fi abil. Laptop arvutitel on see ühendus tänapäeval sisse integreeritud, kuid tavaarvutisse peab ostma selleks lisakaardi. Wi-Fi standardid IEEE 802.11b IEEE 802.11a IEEE 802.11g IEEE 802.11n Wi-Fi (Wireless Fidelity) Kasutatakse k...
