Põhikool BSD Jaanus Taavi Mark Rühm : Tallinn 2014 BSD (Berkeley Software Distribution) on otseselt AT&T Belli laborite UNIX-ist põlvnev kaasaegne vabatarkvaralineoperatsioonisüsteem. BSD arendamist alustati 1970. aastatel California ülikoolis Berkeley-s, sealt tuleneb ka selle omapärane nimi. BSD pere operatsioonisüsteemid on laialdaselt kasutusel ka tänapäeval, levinumad neist on NetBSD,FreeBSD ja OpenBSD. BSD areng Seoses suurenevate nõuetega riistvarale ostis Berkeley 1978. aastal VAX-11/780 miniarvuti.
Operatsioonisüsteem •Opsüsteem on nagu valitsus, kes iseenesest midagi kasulikku ei tee, vaid ainult pakub keskkonna, milles teised programmid saavad töötada. Lühendid •Operating System •Operatsioonisüsteem •opsüsteem •OS OS peab: • Pakkuma keskkonna kus kasutaja saab jooksutada erinevaid programme • Tegema arvuti kasutamise mugavaks • Kasutama arvuti riistvara võimalikult effektiivselt • Tagama riistvara toimimise. • Lahendama veaolukordi. OS'i peamine eesmärk •On muuta arvuti kasutamine mugavaks, võimaldades käivitada kasutajarakendusi ja aidates lahendada veaolukordi. OS mõiste (1) •on arvuti süsteemitarkvara, mis käivitatakse arvutis alglaadimisprogrammi poolt ning mis juhib arvutisüsteemi tööd ja teenindab rakendusprogramme.

Arvutitarkvara liigid Sõltuvalt kasutuslitsentside tüübist ja kasutatavast litsentsilepingute sõlmimise tehnikast võib arvutitarkvara jaotada järgmiselt: • ärivara (commercialware); • jaosvara (shareware); • proovivara (trialware); • vabavara (freeware); • vaba tarkvara (free software); • avalik tarkvara (public domain software). Ärivara (commercialware) Ärivara on peamine arvutitarkvara liik, mida levitatakse tavaliselt infotehnoloogiafirmade, arvutisalongide ja arvutikaupluste kaudu. Enamik suurte tarkvara tootjate tarkvarapakettidest on just nimelt ärivara. Ärivara kasutamine on lubatud alles pärast litsentsitasu maksmist. Vaatamata sellele, et tootjate lõikes võivad litsentsilepingu tingimused erineda, jäävad üldpõhimõtted samaks ja on üldjuhul järgmised:

•Polymorphism is the ability of different classes to define properties or methods with the same name. Polymorphism is essential to object-oriented programming because it allows you to call methods with the same names, no matter what type of object is in use at the moment. 2. COMPONENT TECHNOLOGY – THE PROBLEM The Problem •Today, anything and anyone must be net-enabled. •Automated business processes, products, and software systems need to evolve in „e-Time“. •Everything must be changeable, extensible, adaptable. •Quality is an important issue. Architectural consequences of these requirements: •Software should not be designed as monolithic unit but partitioned into composableservices that can be spontaneously connected and orchestrated by business/technical processes (component-based software). •„Software entropy“should be maximized: loosely coupling between peers,decentralized information access,

My mom says I should be a computer programmer. So that's probably the most preferred future plan. If I had enough money I would go somewhere warm and forget all my future plans, but until I haven't won a lottery I am trying to finish high school. I will have finished this school by the year 2011. My most desired future job is related to computers. After high school I would like to go to Estonian IT College to study about computers software, so I could work as a computer software developer. I am interested in technology, that's why it would be perfect job for the future. Software developer is a highly paid job so I'm kind of hoping that by the year 2020 I'll be a millionaire. I would like to live in Italy by the time I'm 30. By that time I would like to be married with the world's most beautiful woman. I know that I will have to make great efforts to make my dreams come true, but great efforts are guaranteed if I worked as a computer software developer.

a Internet piracy In recent years, internet piracy or "file sharing" of copyrighted material has gained much popularity. It is a topic that has incessantly sparked debate and has even received global attention. Although on the surface the act of file sharing may seem harmless, it is far from it. Each year, film and record production companies as well as software and video game companies suffer from billions of dollars in lost profits. This loss comes as a direct result of internet piracy. Many agree that file sharing is unethical and consider it to be no different than downright theft. On the other hand, there are those that support file sharing and claim that their actions are easily justified and ethical. File sharing simply is the process of making available and distributing files via the internet

Tarkvara Üldiselt mõeldakse tarkvara all kõiki arvutis olevaid programme. Programmiks nimetatakse käskude jada , mis kirjeldab samm-sammult, mida on vaja teha. Iga programmi kasutamine algab selle käivitamisega ja lõpeb selle sulgemisega. Arvutiprogrammid jagunevad kaheks: süsteemitarkvara (system software) ja rakendustarkvara (application software). Süsteemitarkvara ülesandeks on arvuti riistvara ja rakendusprogrammide vahelise koostöö organiseerimine. Süsteemitarkvara tähtsaim komponent on operatsioonisüsteem (operating system). Operatsioonisüsteem on tarkvara, mis määrab, kuidas arvutis programme täidetakse (käivitab, haldab, hooldab, tegeleb ressursijaotusega, juhib andmesisestust ja väljastust) ja tegeleb riistvaraga. On olemas mitmeid erinevaid operatsioonisüsteeme

Applications Architecture The Applications Architecture refers to how useful applications are structured, procured and life cycle managed. Applications Architecture User Systems Architecture Covers all architecture aspects of Information, Technical and Applications Architecture. 3 Modelviewcontroller (MVC) is an architectural pattern used in software engineering. Successful use of the pattern isolates business logic from user interface considerations, resulting in an application where it is easier to modify either the visual appearance of the application or the underlying business rules without affecting the other. In MVC, the model represents the information (the data) of the application; the view corresponds to elements of the user interface such as text, checkbox items, and so forth; and the controller manages the

Like Big Science, high technology is an international phenomenon, spanning continents, epitomized by the worldwide communication of the Internet. Thus a multinational corporation might work on a project 24 hours a day, with teams waking and working with the advance of the sun across the globe; such projects might be in software development or in the development of an integrated circuit. The help desks of a multinational corporation might thus employ, successively, teams in Kenya, Brazil, the Philippines, or India, with the only requirement fluency in the mother tongue, be it Spanish, Portuguese or English.

A main problem I notice when I write essays on my laptop, is all of the distractions that come along with using the computer. I have music and internet at my fingertips and this can dramatically change the quality of writing. With the ability to distract yourself with entertainment it is far too easy to ignore your assignment and encourage writers block. The screen also is tiring to look at and gives me a headache after a while.There are benefits of writing on the computer with word processing software. The writing process is much faster than hand writing. Making corrections and editing your essay is much easier on the computer. While writing Microsoft Word automatically corrects minor spelling errors and capitalizes words for you. This helps me immensely. When I type I hardly ever stop to capitalize and without spell check I would leave many words misspelled and have many more fragmented sentences. By typing on a computer you can get all of your ideas onto your page without having
The collection of e-books takes certainly significantly less room than the same collection of conventional books. An e-reader can potentially contain thousands of e-books, limited only by its memory capacity. Depending on the device e-book may be readable in low light or even in total darkness. For elderly readers or for people with visual problems e-books have a remarkable advantage as the fonts can be enlarged, it I seven possible to use Text-to speech software to read the text. One great thing is the possibility to search for key terms. While an e-book reader costs much more than one book, the electronic texts are generally cheaper. Moreover, a great share of books are available free of charge. For example, all fiction from before the year 1900 is in the public domain. Compared to printed publishing, it is cheaper and easier for authors to self-publish e-books. An

Object-oriented programming. Object-oriented programming (OOP) is a programming paradigm that uses "objects" and their interactions to design applications and computer programs. Programming techniques may include features such as information hiding, data abstraction, encapsulation, modularity, polymorphism, and inheritance. It was not commonly used in mainstream software application development until the early 1990s. Many modern programming languages now support OOP. Class Defines the abstract characteristics of a thing (object), including the thing's characteristics (its attributes, fields or properties) and the thing's behaviors (the things it can do, or methods, operations or features). One might say that a class is a blueprint or factory that describes the nature of something. For example, the class Dog would
VOCABULARY EXERCISES UNIT 5 II Exercise Learning to operate a computer is not as difficult as many people think. Computers can be expensive to buy, but you can often get comprehensive packages containing all the equipment you need at a discount from big companies. Some companies will even install the system for you. Your system will also include various kinds of software such as word- processing and game programmes, all stored on disks. When you put the disk into the computer, the programme or information can be displayed on the screen. Many computer users go on the Internet. This is a system that links computers, making it possible to transmit information from one system to another in a different place via the telephone. This can cause problems, because addicts who use their computers all the time can overload the
Jekaterina Misuna Hypervisor, the powerful open source industry standard for virtualization offers a powerful, efficient, and secure feature set for virtualization of CPU architectures. What is Xen? It supports a wide range of guest operating systems including Windows® Linux® Solaris® BSD operating systems Support With Xen virtualization, a thin software layer known as the Xen hypervisor is inserted between the server's hardware and the operating system. Server Virtualization This provides an abstraction layer that allows each physical server to run one or more "virtual servers" Effectively decoupling the operating system Its applications from the underlying physical server. Server Virtualization The Xen hypervisor is a unique open source technology developed collaboratively by the Xen community and

UNIX'le, kuid pole justkui copy-paste mahategemine. FreeBSD-d peetakse robustseks kuid samas töökindlaks töökindlaks. FreeBSD on täielik operatsioonisüsteem. Tuum, draiverid ja kasutajaliidesed. Installides on tuum, draiverid ja kasutajaliidesed koheselt olemas koos, mitte ei arendada neid eraldi ja siis pakendatakse eri moodi. OpenBSD on vaba ja tasuta, avatud lähtekoodiga ning paljusid riistvaraplatvorme toetav UNIXi-laadne operatsioonisüsteem. OpenBSD põlvneb BSD-st (Berkeley Software Distribution - California Ülikoolis Berkeleys loodud Unix). Projektiga alustas 1995. aasta lõpus Theo de Raadt, kes oma Kanada kodust seda projekti tänaseni koordineerib. OpenBSD logo ja maskott on kerakala nimega Puffy.
HDV records. My JVC camera has 4 compression settings. 5meg, 12 meg, 15 meg and a whopping 24 meg. The 3 lower bit rates are directly compatable with the AVCHD standard for optical disks, so disks made can directly be played on bluray players. The 24 meg format is over the spec for AVCHD, and can only be burned to real BDR disks, or transcoded to a lower bitrate for recording on conventional DVD-R media with compatability with blu ray players. Most editing software these days will handle both HDV and AVCHD formats. When I have done side by side tests comparing my AVCHD camera to my HDV cameras, I am hard pressed to see any real difference. They are very good. When it comes to editing, the AVC format is moch more finicky to work with. If is it a single camera personal video, then I may shoot it on my flash memory camera just because it is convient. If I am shooting anything 2 camera, or any commercial shoots that I know I am going to need to edit, then I
The portability of Java is sometimes overstated games in particular often require some `tweaking' to improve their performance on different OSes/machines, such as in the scheduling of threads, data structure and/or algorithm design, or the choice of GUI components. Also, if legacy code written in a different language is utilised then portability is frequently compromised. Productivity is an important advantage, although hard to quantify. An old study from 1998 suggested that software written in pure Java instead of C++ results in a 25% overall time/cost saving, corresponding to an overall productivity increase of 30% (the increase for the code phase alone is 65%) [Quinn and Christiansen 1998]. It is likely that these figures are greater today since the capabilities of the J2SE have improved (e.g. the libraries are larger, tool speed is better). 2.2. Ways of Using Java in Games There are several approaches to writing games with Java: · Applets
