Learning and living in AIU

Coming to Malaysia was my first experience in traveling abroad. Everything was so unusual and I couldn't believe that I wasn't in Russia anymore. However, after few weeks it became much easier than before.
Living in AIU is something new for most students because now we're living apart from our parents,from our friends. but living in hostel with other girls from different countries is good chance for us to become more independent. When you're living in place,where's a lot of people with their own customs, you must be respectful for that people's culture. And I'm sure that this is very important experience for us because it will be helpful in our future life.

When I came to Malaysia I was scared that it will be very difficult for me to study abroad because starting from now everything will change, I thought so. But now, when my study has already started, I don't worry. I just believe that I'll make everything that in my forces to succeed. Also,that I have parents who believe in me and a lot of new friends help me to be more confident.
In summary, I'd like to say that I really enjoy my learning and living in AIU. And I hope that other students also happy to live and study here. I wish them good luck.

Relational database

The today's topic of our class was Relational database. We have learnt that the database is a collection of interrelated data. And there 4 types of database models. There are such models as hierarchical database, network database, relational database and object-relational database.

Database Management System is a software system for manipulating databases and it has five primary functions: define, create and organize a data, input data, process data, maintain data integrity and security and query database.

It was our last class, so I wish to all of us good luck, we must do our best.

On 10&11 weeks the topic of our classes was Internet. It is global information system and  largest network in the world that connects people/organization all over the world. And it has no formal management organization.

There are different reasons why people use the Internet. This is some of them:

  • Find general information /Access Information.
  • Send (upload) or receive (down load) files between computers.
  • Participate in discussion groups, such as mailing lists and newsgroups.
  • To Correspond/meet with people
  • To learn, read news, find software, buy things
What is web?

  • The World Wide Web also known as web.
  • It contains hypertext links, or highlighted keywords and images that lead to related information.
  • A collection of linked Web pages that has a common theme or focus is called a Web site.
  • The main page that all of the pages on a particular Web site are organized around and link back to is called the site’s home page.
Web Browsers

  • Is a software program that is used to view web page.
  • Web browser works by using a protocol called Hypertext Transfer Protocol (HTTP) to request a specially encoded text document from server.
  • Examples of Web browser: Netscape Navigator (Navigator) and Internet Explorer

Internet Protocol

  • set of rules, or protocol that allow user to transfer file from one computer to another.
  • the most common transfer protocol used on the Internet is the Hypertext Transfer Protocol (HTTP)
  • HTTP: set of rules, or protocol that enables hypertext data to be transferred from one computer to another
  • allow user to retrieve a wide variety of resources such as text, graphics, sound animation and other documents
  • is a protocol used  to access data on web

Web applications

During that classes we have learnt more about Web applications. And we memorized that a Web apps is an app is a piece of software. It can run on the Internet, on your computer, or on your phone or other electronic device. Web browsers are software applications that allow users to retrieve data and interact with content located on web pages within a website.

And there are some examples of Browsers:
  • Internet Explorer
  • Netscape
  • Mozilla Firefox
  • Safari
  • Opera
Web page is a Web document
Types of web pages: 
  •    static web page
  •    dynamic web page
Web Site is a collection of related web pages found at a single address and Web site  has unique address (URL).

Static Web
  •   Web 1.0
  •      considered as "read-only web." allows people to search for information and read it.
  •     Web 1.0 aren’t interactive
  •        closed to external editing
  •        Web 1.0 pages do not allow visitors to contribute
Example: Online official Information resources

There are three main functions of IS:
  • support competitive advantage
  • support business decision making
  • support business operations and processes
Components of CBIS (computer-based information system) are next:

  • Hardware. Consists of  computer  equipment used to perform input, processing and output activities.
  • Software. Consist of computer programs that govern the operation of the computer.
  • Databases is an organized collection of interrelated data (records)
  • People who manage, run, program, maintain
  • Procedures. Strategies, policies, methods and rules for using computer information system including operation, security and maintenance of the computer. 
  • Telecommunications. Electronic transmission of signals for communications which enables organizations to carry out their processes and task through effective computer networks.
Types of IS:

  1. Transaction Processing System (TPS)

  • records the data from everyday operations throughout every division or department in the organization
  • captures and processes data
  • supports unstructured (complex) problems

IT and ICT

On 3 & 4 weeks we have learnt about IT and ICT. This is that we have learnt:
IT (Information technology) is a term that encompasses all forms of technology used to create, store, exchange, and use information in its various forms.

This is concepts of IT:
  • IT architecture:
A map or plan of the information assets in an organisation.
  • IT infrastructure  
The physical facilities, IT components, IT services, and IT personnel that support an entire organization. 

IT components: computer hardware, software, and communications technologies.  
IT services: Services provided for people/customer e.g.Data   management, systems development and security     management.
IT Personnel: people/individual work with IT&IS 

Apart from that Information and Communication Technology (ICT) refers to technologies that provide access to information through telecommunications. It focuses primarily on communication technologies.

But what about usage of ICT in daily life?

  • Education
  • Banking
  • Business
  • Government
  • Science
  • Healthcare


Data, Information, Information Management (IM)

During that classes we have learnt what do data, information and IM mean. For example, data is raw facts. Data can be in the form of numbers, symbols, characters or even sounds. Apart from that, information is data
that is organized and meaningful. So, computers process data into information.

But what is the role of information? Information is used in decision-making. Information is used to influence and persuade. Information can be a capital resource, especially for companies that produce information-based products and services.         
Information has two basic elements:           
  • Reach
  • Richness. Richness has three components: bandwidth, customization and interactivity.

Information management (IM) is the collection and management of information from one or more sources and the distribution of that information to one or more audiences.

To summ up, I would like to say that, data is a collection of facts, figures and statistics related to an object. Information is the manipulated and processed form of data. And Information management is a general terms that refers to managing any kind of information.
