The Internet is a global system of interconnected computer networks that use the standard Internet Protocol (TCP/IP) to serve billions of users worldwide. It is a mother of all networks that consists of millions of private, public, academic, business, organizations and government networks of local to global scope that are linked by a broad array of electronic and optical networking technologies.

HISTORY OF INTERNET (BASED FROM WIKIPEDIA.COM)

The concept of data communication - transmitting data between two different places, connected via some kind of electromagnetic medium, such as radio or an electrical wire - actually predates the introduction of the first computers. Such communication systems were typically limited to point to point communication between two end devices. Telegraph systems and telex machines can be considered early precursors of this kind of communication. The earlier computers used the technology available at the time to allow communication between the central processing unit and remote terminals. As the technology evolved new systems were devised to allow communication over longer distances (for terminals) or with higher speed (for interconnection of local devices) that were necessary for the mainframe computer model. Using these technologies it was possible to exchange data (such as files) between remote computers. However, the point to point communication model was limited, as it did not allow for direct communication between any two arbitrary systems; a physical link was necessary. The technology was also deemed as inherently unsafe for strategic and military use, because there were no alternative paths for the communication in case of an enemy attack.

As a response, several research programs started to explore and articulate principles of communications between physically separate systems, leading to the development of the packet switching model of digital networking. These research efforts included those of the laboratories of Vinton G. Cerf at Stanford University, Donald Davies (NPL), Paul Baran (RAND Corporation), and Leonard Kleinrock at MIT and at UCLA. The research led to the development of several packet-switched networking solutions in the late 1960s and 1970s, including ARPANET, Telenet, and the X.25 protocols. Additionally, public access and hobbyist networking systems grew in popularity, including unix-to-unix copy (UUCP) and FidoNet. They were however still disjointed separate networks, served only by limited gateways between networks. This led to the application of packet switching to develop a protocol for internetworking, where multiple different networks could be joined together into a super-framework of networks. By defining a simple common network system, the Internet Protocol Suite, the concept of the network could be separated from its physical implementation. This spread of internetworking began to form into the idea of a global network that would be called the Internet, based on standardized protocols officially implemented in 1982. Adoption and interconnection occurred quickly across the advanced telecommunication networks of the western world, and then began to penetrate into the rest of the world as it became the de-facto international standard for the global network. However, the disparity of growth between advanced nations and the third-world countries led to a digital divide that is still a concern today.

Following commercialization and introduction of privately run Internet service providers in the 1980s, and the Internet's expansion for popular use in the 1990s, the Internet has had a drastic impact on culture and commerce. This includes the rise of near instant communication by electronic mail (e-mail), text based discussion forums, and the World Wide Web. Investor speculation in new markets provided by these innovations would also lead to the inflation and subsequent collapse of the Dot-com bubble. But despite this, the Internet continues to grow, driven by commerce, greater amounts of online information and knowledge and social networking known as Web 2.0.

THE USES OF THE INTERNET ARE THE FOLLOWING:
1. EDUCATION
2. TRANSPORTATION
3. GOVERNMENT
4. ENTERTAINMENT
5. COMMUNICATION

A database consists of an organized collection of data for one or more users. It contains records and fields in which fields are represented by the column and records are represented by rows. 

(Below are information collected form Wikipedia.org)

Operational database

These databases store detailed data about the operations of an organization. They are typically organized by subject matter, process relatively high volumes of updates using transactions. Essentially every major organization on earth uses such databases. Examples include customer databases that record contact, credit, and demographic information about a business' customers, personnel databases that hold information such as salary, benefits, skills data about employees,manufacturing databases that record details about product components, parts inventory, and financial databases that keep track of the organization's money, accounting and financial dealings.

[] Data warehouse

Data warehouse archive historical data from operational databases and often from external sources such as market research firms. Often operational data undergoes transformation on its way into the warehouse, getting summarized, anonymized, reclassified, etc. The warehouse becomes the central source of data for use by managers and other end-users who may not have access to operational data. For example, sales data might be aggregated to weekly totals and converted from internal product codes to use UPC codes

Analytical database

Analysts may do their work directly against a data warehouse, or create a separate analytic database for Online Analytical Processing. For example, a company might extract sales records for analyzing the effectiveness of advertising and other sales promotions at an aggregate level.

Distributed database

These are databases of local work-groups and departments at regional offices, branch offices, manufacturing plants and other work sites. These databases can include segments of both common operational and common user databases, as well as data generated and used only at a user’s own site.

End-user database

These databases consist of data developed by individual end-users. Examples of these are collections of documents in spreadsheets, word processing and downloaded files, or even managing their personal baseball card collection.

External database

These databases contain data collect for use across multiple organizations, either freely or via subscription. The Internet Movie Database is one example.

Hypermedia databases

The World Wide Web can be thought of as a database, albeit one spread across millions of independent computing systems. Web browsers "process" this data one page at a time, while web crawlers and other software provide the equivalent of database indexes to support search and other activities.

Advantages and Disavantages of IT Gadgets................

    Laptops, cellphones, i-pods, cameras, net books are all gadgets. It may give us pleasures  and benefits to our daily activities in work and in school but actually it can also brought disadvantages to us.

Multitasking & Study Habits

CAREER PLANNING....... HOW WILL YOU PLAN AND MANAGE YOUR FUTURE CAREER?

The Building Blocks of Career Planning
Although career planning may seem overwhelming, following the steps in these four building blocks will help you research and attain your career goal:

		SELF ASESSMENT Create a personal inventory of your skills, interests, values, personality and learning style.
		RESEARCH Learn as much as you can about careers that interest you - how much does it pay, what are the working conditions, etc.
		MAKE A FIT It's now time to decide how to match your personal inventory with careers that require your strengths and skill sets.
		CREATE A PLAN This may include locating an education program, selecting a school, financial aid, resume preparation, standardized admission tests and interviewing techniques.

Keep reading for more information on how to structure your career planning:



Don't be modest - do be honest! Create a personal inventory of your strengths and skill sets by following these steps:

1. Write a list of skills you have acquired.
For example:

• Basic skills - such as reading, writing, speaking, listening
• Social skills - such as teaching, negotiation, persuasion
• Technical skills - such as analysis, trouble-shooting, decision making
• Management skills - such as time management, motivation and direction of others, management of financial and material resources

2. What are your interests?
Create a list of activities and interests that you have really enjoyed in the last five years. Is there a common theme?

3. What do you value in the workplace?
Create a list of what you need in the job environment. For example, you may value some of the following: Feel that your work makes a difference. Job security. Have regular hours. Work as a team. Work independently. Have respect and status. Helping others. Salary. Work with your hands. Work outdoors.

4. What is your learning style?
Online learning is different in many respects from the traditional face-to-face learning we're all used to, primarily in the way we get our information and how we interact with instructors and classmates. Many people say they learn more online, and their retention is better too.



Learn as much as you can about the careers that interest you:

	From what you have learned in the step above, create a short list of careers you are interested in.
	For each career that interests you, prepare and conduct an information interview with a person already employed in that occupation.
	Write to professional organizations requesting more information on the profession and potential contact names.
	Other methods to research potential careers include job shadowing, volunteering, contract employment, work-study programs and summer employment.

Finding that perfect match
It's now time to decide how to match your personal inventory with careers that require your strengths and skill sets.

	Examine what you learned about yourself when you completed the steps in your self-assessment.
	Review the occupations you have researched.
	Now compare your interests and skills with those occupations.
	Determine which career best matches your values, personality, skills and interests.

Now you're ready to move on to creating a plan to attain your career goal . . .




Time for Action
Now that you have a career goal, an action plan needs to be created.
Here are the top things to consider when creating your plan:

	Determine what educational requirements are necessary for your career. Do you need a degree, a certificate, just a few courses or vocational training?
	Determine which schools will provide you with the education you need. Which school best meets your needs? Consider your lifestyle and family needs. Are classes offered at a convenient time for you? Is the school accredited?
	What are the admissions requirements and procedures? In some cases, you may have to write an entrance test or exam.
	What is the cost of the education required? Will you require financial aid? Could you qualify for a scholarship. Are loans or grants available to you?
	What is a realistic time frame to reach your career goal? Will you study full-time or part-time?

GOOD STUDY HABITS OF A RESPONSIBLE STUDENT

The Ten Study Habits of Successful Students

          Successful students have good study habits. They apply these habits to all of their classes. Read about each study habit. Work to develop any study habit you do not have.

Successful students:

1. Try not to do too much studying at one time - If you try to do too much studying at one time, you will tire and your studying will not be very effective. Space the work you have to do over shorter periods of time. Taking short breaks will restore your mental energy.
2. Plan specific times for studying - Study time is any time you are doing something related to schoolwork. It can be completing assigned reading, working on a paper or project, or studying for a test. Schedule specific times throughout the week for your study time.
3. Try to study at the same times each day - Studying at the same times each day establishes a routine that becomes a regular part of your life, just like sleeping and eating. When a scheduled study time comes up during the day, you will be mentally prepared to begin studying.
4. Set specific goals for their study times - Goals will help you stay focused and monitor your progress. Simply sitting down to study has little value. You must be very clear about what you want to accomplish during your study times.
5. Start studying when planned -You may delay starting your studying because you don't like an assignment or think it is too hard. A delay in studying is called "procrastination." If you procrastinate for any reason, you will find it difficult to get everything done when you need to. You may rush to make up the time you wasted getting started, resulting in careless work and errors.
6. Work on the assignment they find most difficult first - Your most difficult assignment will require the most effort. Start with your most difficult assignment since this is when you have the most mental energy.
7. Review their notes before beginning an assignment - Reviewing your notes can help you make sure you are doing an assignment correctly. Also, your notes may include information that will help you complete an assignment.
8. Tell their friends not to call them during their study times - Two study problems can occur if your friends call you during your study times. First, your work is interrupted. It is not that easy to get back to what you were doing. Second, your friends may talk about things that will distract you from what you need to do. Here's a simple idea - turn off your cell phone during your study times.
9. Call another student when they have difficulty with an assignment - This is a case where "two heads may be better than one."
10. Review their schoolwork over the weekend -Yes, weekends should be fun time. But there is also time to do some review. This will help you be ready to go on Monday morning when another school week begins.

          These ten study habits can help you throughout your education . If you follow these 10 study habits, I may say that you are a responsible student and you might be one of the honors nor get an award in  your school when you graduate. 

 

EITSC SEMINAR.... ON PROJECT MANAGEMENT

     I have attended the EITSC's 3-days seminar conducted at UMAK- University of Makati entitled Project Management. It was joined by different  local universities. Foods and snacks are all free including certificates. first day - discussion time, second day - question and answer portion, boding with lecturer, 3rd day- presentation and giving of certificates.

    I really enjoy this seminar cause I learned a lot on how to start and manage an IT project. It's almost similar with the Feasibility and Thesis subjects which I am currently handling. I am really interested with the FTB, how to include FTB in the cost estimates. 

   I really enjoy it!!!  Thanks for this chances to attend in this kind of seminar..
