Introduction to Computer Networks
We had a research about the library networks of different countries. I can see that library networks are not that prevalent here in the Philippines. Only few are here and we are not that fully aware. Comparing the library networks of the Philippine to other countries, they are more developed and they are still working for its improvement. This leads us to the question on why, what happened to the library network here in the Philippines? We may say that the country cannot establish library networks because of our economy status and we belong to the third world countries. But if we are to look in the other third world countries like the India they have a lot of library networks like the INDONET data Network, BONET (Bombay Library Networks), SIRNET (Scientific and Industrial Research Network), etc. since 1980s. Do they have a better program for their library network than the Philippines? Do they have a better information technology infrastructure? Or are they well-supported by their government?

Abstract:
In this contribution, we identify and clarify some distinctions we believe are useful in establishing the reliability of information on the internet. We begin by examining some of the salient features of information that go into the determination of reliability. In so doing, we argue that we need to distinguish content and pedigree criteria of reliability of information from the issues of the accessibility and the usability of information. We then turn to an analysis of some common failures to recognize reliability or unreliability.
Salient points:
The reliable information is the justified information that means justified in believing and information we can trust. There are two broad categories criteria we can use to determine the reliability of information; the content and pedigree criteria. Content criteria means the condition or criteria of reliability that are a function of the content of the information itself while pedigree criteria is the conditions or criteria of reliability that are a function of the source of information. Accessibility and usability are the other features of information that is linked with the reliability of information. Determining reliability consists to a large extent in recognizing that the appropriate pedigree criteria are satisfied. Failure to recognize the reliability of the information can take many forms: the appropriate pedigree criteria might be missing or inadequate, even though adequate pedigree criteria is are present, the underlying credibility conferring institution might not be recognized as such by a particular user, and pedigree criteria can sometimes appear to conflict with each other or with content criteria.

Sugnificant Learning Outline
Introduction to Computer Networks
On the first day of our meeting, we had a discussion on the introduction of information networks. Its history is connected with the history of internet. ARPANET (Advanced Research Projects Agency Network), created by the Defense Advanced Research Projects Agency (DARPA) of the United States Department of Defense, was the world's first operational packet switching network, and the predecessor of the contemporary global Internet in 1969. It was just on the 1970’s when the networks become cost-effective and reliable for ordinary computer users to transmit data between computers over long distances.

Quiz 2
1. Differentiate open access and proprietary software. Give one example each to illustrate your view.
Open access software is a free or no cost that can be used by anybody. It can be
also modify, change or alter by everybody using the program. It is up to us to fix its features because technical support will be there. Thus,, open access requires a continuous training for familiarity and become an expert on the program. Examples the Greenstone Digital Library which is a free software to be used and to be installed. We can alter or enhance some of its features if we are familiar and we have enough training to do so.
Proprietary software is usually owned by an individual or company. It is not for free it is for sale. You have to buy it when you want to have it. Features are already fix through you can alter but only its minimal like the color s and its interface. Any technical problem will be solved by the one who owned the program. They are the one responsible to fix it. Their technical support. Though it needs training but only during the first time for familiarity on the said program. Example of this is the Alexandria or Follett. Their features are fix and it is just up to us to input or encode the information need for information access.
2.
Free access to information is a right given to every individual. Just like right to know or right to information, this goes along with the freedom to give your thoughts or views. Thus, free access is not only for us to receive and consumed information in our environment. It is the opportunity given to us to share our views, opinions and ideas. We can express our thoughts for a certain thing in our blogs or make comments. Through free access, we can also publish our works like books or researches to be made available to anybody who wishes to read it. Thus, identity will be build up and name will be know.

Quiz 1
Name : INDONET data Network
History:
Started in March 1986 by CMC Ltd.In phase I, an experimental INDONET Pilot Satellite Network (IPSN) incorporating all the features of the proposed INDONET was worked out. IPSN connects nodes in Bombay, Calcutta, Madras, Delhi, Hyderabad, Bangalore, Vishakhapathnam, Ahmedabad and Pune with IBM 436 computers and MUXs/cluster controllers. The network uses IBM's Computers and Systems Net-work Architecture and 4800 bps leased lines, 9600 bps packet radio links for intra-city connection. In the second phase, the INDONET would operate as a Star Network with control point in Delhi using root top 3-m earth stations and packet switching. Beside SNA, it will also support X.25 protocols satellite and radio communication the INDONET is expected to cover 35 major cities of India. The CMC Ltd. is closely involved with NISSAT activities in library networking programmes in Calcutta and Delhi.

Webliography of Library Online Resources
A. Name of Library: Online Burma/Myanmar Library
Library’s URL: http://www.burmalibrary.org/introduction.html
Type of Library : Public
About the Library :
The Online Burma/Myanmar Library is a database which functions as an annotated, classified and hyperlinked index to full texts of individual Burma documents on the Internet. It also houses a growing collection of articles, conference papers, theses, books, reports, archives and directories on-site (e.g. the 17MB archive of the Burma Press Summary). The Librarian requests help from specialists to refine the structure and add content. It was launched in October 2001. The Library's starting point historically was the Burma Peace Foundation's documentation of the human rights situation in Burma , and with the UN Burma material, this area still comprises about half the total number of items.
Name and Description of the Program:
1. MySQL software, in combination with PHP
Launched in October 2001, these programs was used to organized on a database into 60 top-level categories based on traditional library classifications, with a hierarchy of some 850 sub-categories. These hold approximately 4000 links (mostly annotated, with keywords and descriptions) to individual documents, and about 400 links to websites which in turn give access to another 100,000 or so documents. The database allows rapid searching in all or specific fields – description/keyword, date, language (we are building up our collection of non-English texts), title, author, source/publisher etc. It can also be browsed through the subject hierarchies. A third way of finding material is provided by a simple alphabetical list of the 900 categories and sub-categories.
