I - SEARCH ENGINES

Advantages:

o The first and foremost advantage is that it helps you in increasing the traffic to your website via various search-engines by improving the visibility of your website to the public.

o The other big advantage with search-engine-optimization is that you need not spend any of your valuable money to improve the traffic to your website; after all organic SEO is the best way of obtaining a permanent and long standing website. So, I consider this as the biggest advantage with search engine optimization. You earn without spending. In short, SEO is more affordable than any other means of improving website traffic.

Disadvantages:

o The biggest disadvantage is that only technical geeks can have the mastery over this. The concept of search engine optimization is to provide the relevant topics to the user who types in the particular word/phrase/sentence. So the owner of the website must be clever and capable enough to understand these things and move accordingly. He/she has to out think the public and create keywords that are used frequently by most users.

II - INDIVIDUAL SEARCH ENGINES AND META SEARCH ENGINES

Both are search tools/software.

However

individual search engine
searches for a topic of your choice and returns matches. Search engine is often used synonymously with spider and index. A spider or web crawler is the software that scans documents and adds them to a search engine's index by following links, examples:

Google
Yahoo
Bing - (Formerly MSN Live)
Google Scholar
AOL Search
Ask

while;

meta search engines
These search engines are useful if you need to run a comprehensive search quickly across a number of different engines, to compare results or to suggest search engines that you may not have tried before. The majority do a Google, Yahoo, MSN, Ask search (GYMA, or GYM search depending), but there are differences./ It sends user requests to several other search engines and/or databases and aggregates the results into a single list or displays them according to their source. Metasearch engines enable users to enter search criteria once and access several search engines simultaneously. Metasearch engines operate on the premise that the Web is too large for any one search engine to index it all and that more comprehensive search results can be obtained by combining the results from several search engines.

III - When to use:

*Search Engine

You know what you're looking for, and can describe it with some key words or phrases.
Google is always a good bet, since it has the largest index
Yahoo Search is the second most popular keyword search engine
Bing may provide results if the other two don't work
Exalead is an excellent choice and makes a change from the big 3

*Search/Subject Directory

These search engines arrange data in hierachies from broad to narrow.

Good if you need an overview of a subject or you're not entirely sure of what you want.
Yahoo Directory provides 14 main categories
Google Directory provides access to 16 main categories
Virtual libraries from Pinakes. Drill down for the content/sites you need
The Open Directory Project provides access to 16 main categories.

A subject directory is a catalog of sites collected and organized by humans.Subject directories are often called subject "trees" because they start with a few main categories and then branch out into subcategories, topics, and subtopics.

To find the homepage for the Atlanta Braves at Yahoo!, for example, select "Recreation & Sports" at the top level, "Sports" at the next level, "Baseball" at the third level, "Major League Baseball" at the fourth level, "Teams" at the fifth level, then finally "Atlanta Braves."

New Procedure Opens Arteries after Angioplasty

Cardiologists and radiologists at Mary Mercy Hospital today at 1:30 pm will perform a procedure they think may be the answer to restenosis, the renarrowing of coronary arteries after angioplasty. Beta radiation will be used to reduce thickened vessel tissue that is sealing off vital blood flow to the heart. The procedure has been perfected in academic medical centers and is being offered for the first time in Washington State.

Dr. Emmett Cujo, a board certified cardiologist, and his colleague, Dr. Edwina Morose, a board certified radiologist, will be performing the operation in Mary Mercy's new operating theater. The patient will undergo surgery at 1:30 and radiation therapy at 2:00pm. Both Dr. Cujo and Dr. Morose will be available at 2:30 to meet with the press and public to answer questions.

Angioplasty vs Angioplasty Plus Beta Radiation

Number of Patients and Characteristics	Angioplasty Data
	Angioplasty Alone	Angioplasty Plus Beta Radiation
1,587,000 patients with blocked arteries	900,000	100,000
5 year survival rate	80%	94%
Cost per procedure	$7500	$8500

Angioplasty, the process of inserting a tiny balloon into an artery leading to the heart in order to push out the plaque that is reducing blood flow, and therefore oxygen, to the heart, often fails over time as the artery walls renarrow in about 20 percent of the patients. The new therapy uses Beta radiation pellets left within the vessel for three to five minutes. The vessel tissues absorb radiation which prevents thickening of the walls. The risk of employing the treatment is low, as the beta source radiation used in this procedure amounts to one percent of radiation exposure from a chest X-ray.

It is less costly than other heart surgery
It is a more appropriate use of technology (for those patients who are suitable for the procedure)
It causes less discomfort to the patient.

"Mary Mercy hospital staff are excited about using this new technique both because of the increased survival rate for patients and because the procedure adds such a small amount to the cost of the procedure," says Dr. Mignon Evers, Mary Mercy's Medical Director.

genesis:

What were the circumstances that drove the people during that time to developed technologies towards inter-networks?
How did the different technologies contribute to the evolution of the modern Internet?
If you could change or improve something in the internet and/or its services, what would it be?

The USSR's launch of Sputnik drove the US to have technological advancement. Breakthrough such as that had to be overdone. Communication technologies (more specifically the US military) at the time had found a curiosity that had to be quenched, how can their means of staying 'connected' or in sync as a network be tested to survive?
United States created the Advanced Reasearch Project Agency(ARPA). ARPA created the Information Processing Technology Office (IPTO) to address the concern and further the research of the (SAGE) program, which had networked country-wide radar systems together for the first time.
As a first step interconnect their computers at the Pentagon, Cheyenne Mountain, and SAC HQ.

Not much on the specifics but it could be that what led to the development of inter networks can be donned on the competition for technological breakthroughs, the prized credit of innovation of one country over another, and the upgrading of present or already existing technologies (computers(softwares and hardwares) IMP, NCP, TCP, Packet Switching, ) to much greater use, the advancement of communication and information technology.

The internet has given the modern man immense abilities. From being able to access information easily at the click of a mouse or touch of the keypad, to allowing work done in great flexibility in time and location. If anything at all could be improved on the internet and its services, it would be that which we deem impossible now, perhaps like the ability to transmit a physical matter into the network and to let it materialize in a desired destination. I could think of nothing to change on the internet, except perhaps the nullity of virus on it and its users. All in all, the internet has granted us what the men of old and ancient would deem as magical and mystic, to be able to commuinicate with people from miles across the earth? At a speed of a sneeze quite likely? Was impossible for them. What more could we possibly make of it?
