ÖNEMLİ

Sevgili Öğrenciler,

2 Ocak gününe hazırlayacağınız ödev aşağıda.

Bunun yanı sıra aynı güne şöyle bir ek ödev istiyorum.
Bunu yapmak seçimlik (optional). Yapmayan ilk başta belirttiğimiz %100'den birşey kaybetmez. Ancak yapana ilave 4 puana kadar eklenebilir. Vize notlarının düşüklüğü ve bazılarının ödev eksiklerini dikkate alarak bunu planladım. Şimdiden başlamanızı öneririm. Final ilk hafta olur ise, final günü de getirebilirsiniz. Ama DAHA GEÇ KESİNLİKLE KABUL EDİLEMEZ.

Sizden istediğim, bilgisayar teknolojileri (veya iletişim teknolojileri veya eğitim-öğretim Teknoljileri) hakkında YENİ bir teknoloji hakkında en az yarım sayfalık İng. bir yazı bularak bunu Türkçeye çevirmeniz.

Değerlendirme ölçütleri
1) YENİ bir teknoloji olması
2) İmla ve diğer yazım kuralları. Noktalama işaretlerinden sonra boşluk konması gibi.
3) Türkçenizin doğruluğu ve düzgünlüğü
4) Kaynak belirtme
5) Okunaklı bir punto, raporda düzgün/estetikk bir görünüm
6) Sağ üstte isim soyad
7) Üst ortalanarak başlık
8) Birden fazla sayfanız olur ise, sağ alta sayfa no ve bu durumda zımbalayarak getiriniz, naylon zarf istemiyorum.

Kolay gelsin,
Filiz Eyüboğlu

Homework-8, Due Date: Jan. 2, 2008

Translate the following text onto Turkish.

What is the Web?

The World Wide Web (commonly shortened to the Web) is a system of interlinked, hypertext documents accessed via the Internet. With a web browser, a user views web pages that may contain text, images, videos, and other multimedia and navigates between them using hyperlinks. The World Wide Web was created in 1989 by Sir Tim Berners-Lee, working at CERN in Geneva, Switzerland.

How the Web works?

Viewing a web page on the World Wide Web normally begins either by typing the URL of the page into a web browser, or by following a hyperlink to that page or resource. The web browser then initiates a series of communication messages, behind the scenes, in order to fetch and display it.
First, the server-name portion of the URL is resolved into an IP address using the global, distributed Internet database known as the domain name system, or DNS. This IP address is necessary to contact and send data packets to the web server.

The browser then requests the resource by sending an HTTP request to the web server at that particular address. In the case of a typical web page, the HTML text of the page is requested first and parsed immediately by the web browser, which will then make additional requests for images and any other files that form a part of the page. Statistics measuring a website's popularity are usually based on the number of 'page views' or associated server 'hits', or file requests, which take place.

Having received the required files from the web server, the browser then renders the page onto the screen as specified by its HTML, CSS, and other web languages. Any images and other resources are incorporated to produce the on-screen web page that the user sees.

Most web pages will themselves contain hyperlinks to other related pages and perhaps to downloads, source documents, definitions and other web resources. Such a collection of useful, related resources, interconnected via hypertext links, is what was dubbed a "web" of information.

FINAL EXAM

Final sinavı, vize2 gibi, ağırlıklı olarak açık uçlu soru, boşluk doldurma ve D/Y şeklinde olacak. Bu sebeple çalışmanızı hatırlatırım. En temel konuları bilmemenizden ve de çalışmamanızdan ötürü her iki vize sınavında da notlarınız düşük oldu. 3. sınıf BÖTE öğrencisi source program / object program'ı bilmeli!!!! Web'in ne olduğunu da tam olarak bilmeli. Bilgisayar bölümünde okumayanlardan daha doğru düzgün tarif edebilmeli. ALU ve CU'yu da bilmeli, ki bunlarla ilgili olarak size sorulan, bir iki cümlelik çok basit ve temel açıklamalar, tanımlar... ama büyük çoğunluk bilmiyor :(
Bilgisayar konularını çalışınız. EBT-1 notlarınıza göz atmanız yararlı olabilir.

Source program & Object program + Supervisor program (kernel)

Which one is TRUE???

* Compiler takes an object program as input and translate it into source program.

* Compiler takes a source program as input and translate it into object program.

ANOTHER FEEDBACK:
Pls read http://fileforums.com/showthread.php?t=47548 to see the difference between BIOS and the supervisor program (kernel).

Dec 5, 2007: C, C++, LAN, WAN, The Internet

The History of C & C++

C++ evolved from C, which evolved from previous two programming languages, BPCL and B. (.....).

The C language was evolved from B, by Dennis Ritchie at Bell Laboratories and was originally implemented on a DEC PDP-11 computer in 1972 ...

C uses many important concepts of BPCL and B while adding data typing and many other features. C initially became widely known as the development language of the UNIX operating system. Today, most operating systems are written in C and/or C++. C is now available for most computers. C is hardware independent. With careful design, it is possible to write C programs that are portable to most computers.

Writing C++ Statements

Write a C++ statement to accomplish each of the following
tasks:
a) Declare a variable sum and x to be of type int.
b) Initialize variable x to 1.
c) Initialize variable sum to 0.
d) Add variable x to variable sum and assign the result to variable sum.
e) Print “The sum is: “ followed by the value of variable sum.

Computer Networks

Often organizations use a network of personal computers, which allows users to operate independently or in cooperation with other computers, exchanging data and sharing resources. Such a setup is called a local area network (LAN).
Wide Area Network (WAN) is a computer network that covers a broad area (i.e., any network whose communication links cross regional or national boundaries). Or, less formally, a network that uses routers and public communication links.

The largest and most well-known example of a WAN is the Internet.
Users who connect their computers via the phone lines must use a hardware called a modem to reconcile the inherent differences between computers and the phone system.

The Internet

The Internet is a worldwide, publicly accessible series of interconnected computer networks that transmit data by packet switching using the standard Internet Protocol (IP).
It is a "network of networks" that consists of millions of smaller domestic, academic, business, and government networks, which together carry various information and services, such as electronic mail, online chat, file transfer, and the interlinked web pages and other resources of the World Wide Web (WWW).
With a software called browser, a user can manipulate a mouse to point and click on screen text or pictures to explore the Internet, particularly the World Wide Web (www or the Web), an Internet subset of text, images, and sounds linked together to allow users to view a site.
A home page is the first page of a Web site.
