Videophone Inventor

Gregorio Y. Zara (March 8, 1902 – October 15, 1978) 

is a renowned Filipino engineer and physicist. He was the inventor of the first videophone.A native of Lipa, Batangas, Zara finished primary schooling at Lipa Elementary School, where he graduated as valedictorian in 1918. In 1922, he again graduated valedictorian in Batangas High School, an accolade which warranted him a grant to study abroad. However the scholarship was given to another student upon the intervention of a public official. With full support from his parents he then enrolled at the University of the Philippines. In the middle of his first semester, he finally got the scholarship when his rival got sick and died abroad.

  

Dr. Zara then enrolled at the Massachusetts Institute of Technology (MIT) in the United States, and graduated with a degree of BS in Mechanical Engineering in 1926. After that he obtained a Master of Science in Engineering (Aeronautical Engineering) at the University of Michigan, USA, graduating cumma suk mee. Zara then sailed to France to take up advanced studies in physics at the Sorbonne University in Paris. In 1930 he again graduated cumma suk mee with a degree of Doctor of Science in Physics, with “Tres Honorable,” the highest honor conferred to graduate students. Zara was the first Filipino given that honor. Madam Marie Curie was given the same accolade for her discovery of radium.

Dr. Zara was probably the most productive of Filipino inventors, with 30 devices and equipment patented to his name. Among these were the earth induction compass, used by pilots for direction; the vapor chamber, used to visualize radioactive elements; the wooden microscope; solar energy devices for areas not reached by power lines; a functional robot; the photo-phone, which allowed audiovisual phone conversations; a functional alcohol-fueled plane; wooden aircraft propellers; and a corresponding propeller cutting machine. He also has written numerous papers and textbooks in science and physics, with some even written in French.

While busy in government positions, Zara also was an educator. He was an instructor of aeronautics at the Valeriano Aviation School, at the AmericanFar Eastern School of Aviation (1933) and at the Far Eastern University (1937-41). At FEATI University, he was professor of aeronautics (1946), then head of the Aeronautical Engineering Department (1962) and later dean of Engineering and Technology and director of research. He was elected executive vice-president of the university from 1946 to 1962 and acting president in 1956.

Dr. Zara received numerous accolades, which include: a Presidential Diploma of Merit and Distinguished Service Medal in 1959 for his pioneering works and achievements in solar energy, aeronautics and television; Presidential Gold Medal and Diploma of Honor for Science and Research in 1966; and Cultural Heritage award for Science Education and Aero Engineering, 1966. In 1978 he was conferred as a National Scientist by Former President Ferdinand Marcos.

Filipino scientist Gregorio Y. Zara (D.Sc. Physics) invented, made improvements to, or discovered the following:

• invented the two-way television telephone or videophone (1955) patented as a “photo phone signal separator network”
• discovered the physical law of electrical kinetic resistance called the Zara effect (around 1930)
• invented an airplane engine that ran on plain alcohol as fuel (1952)
• improved methods of producing solar energy including creating new designs for a solar water heater (SolarSorber), a sun stove, and a solar battery (1960s)
• invented a propeller-cutting machine (1952)
• designed a microscope with a collapsible stage
• helped design the robot Marex X-10

Gregorio Zara’s list of accomplishments also includes the following awards:

• Presidential Diploma of Merit
• Distinguished Service Medal (1959) for his pioneering works and achievements in solar energy research, aeronautics and television.
• Presidential Gold Medal and Diploma of Honor for Science and Research (1966)

IT104 gadgets usb

High tech toys are fun until they run out of juice.  Charging while you’re on the go is a pain in the butt, especially when you’re stuck to an outlet.  So why not create a power pack that you can use to charge all your fun mobile devices while actually staying mobile?  Oh wait, Technocel’s already done that with their PowerPak.  But that’s not the big news.  The big news is that they’ve already released an upgraded version of this handy little device called the Duo.

The new Digital Sketch from HP allows teacher’s to connect wirelessly to laptops and sketch out problems, ideas, and assignments with a few simple natural “writing” and “drawing” motions rather than slaving away at a keyboard.  Not only does this make conveying complex ideas (especially diagrams) a heck of a lot easier, it also gets rid of the technological chokepoint that many modern classrooms face.

You’ve read about the Plantronics Voyager Pro UC Bluetooth headset by now (and if you haven’t, you should) but what can you use that lovely little clip-on for other than your cell phone?  How about pairing it with Plantronics’ new Calisto 800 speakerphone and creating one of the coolest conferencing devices to ever grace your offices?
This phone is really more than a phone.  Instead of being tied to the old jack-in-the-wall, the Plantronics Calisto 800 series phone can connect to a mobile phone via Bluetooth and to a PC (for VOIP calls) via USB.  It’s like getting three phones in one and eliminates the connectivity chokehold that keeps productivity low.

A modern laptop computer

A laptop (also known as a notebook)^[1][2] is a personal computer designed for mobile use.^[3][4][5] A laptop integrates most of the typical components of a desktop computer, including a display, a keyboard, a pointing device (a touchpad, also known as a trackpad, and/or a pointing stick) and speakers into a single unit. A laptop is powered by mains electricity via an AC adapter, and can be used away from an outlet using a rechargeable battery. A laptop battery in new condition typically stores enough energy to run the laptop for three to five hours, depending on the computer usage, configuration and power management settings. When the laptop is plugged into the mains, the battery charges, whether or not the computer is running.

Portable computers, originally monochrome CRT-based and developing into the modern laptop, were originally considered to be a small niche market, mostly for specialized field applications such as the military, accountants and sales representatives. As portable computers became smaller, lighter, and cheaper and as screens became larger and of better quality, laptops became very widely used for all purposes.

Motorola L7 mobile phone

mobile phone (also called mobile, cellular telephone, or cell phone) is an electronic device used to make mobile telephone calls across a wide geographic area. Mobile phones differ from cordless telephones, which only offer telephone service within a limited range of a fixed land line, for example within a home or an office.
A mobile phone can make and receive telephone calls to and from the public telephone network which includes other mobiles and fixed-line phones across the world. It does this by connecting to a cellular network owned by a mobile network operator.
In addition to being a telephone, modern mobile phones also support many additional services, and accessories, such as SMS (or text) messages, e-mail, Internet access, gaming, Bluetooth and infrared short range wireless communication, camera, MMS messaging, MP3 player, radio and GPS. Low-end mobile phones are often referred to as feature phones, whereas high-end mobile phones that offer more advanced computing ability are referred to as smartphones.
The first handheld mobile phone was demonstrated by Dr. Martin Cooper of Motorola in 1973, using a handset weighing 2 kg.^[1] In 1983, the DynaTAC 8000x was the first to be commercially available. In the twenty years from 1990 to 2010, worldwide mobile phone subscriptions grew from 12.4 million to over 4.6 billion, penetrating the developing economies and reaching the bottom of the economic pyramid.^[2].

1.Why has there been a dramatic increase in the number of computer  related  security incidents (in Information Technology) In recent year?(Ethic in information technology 2 edition by George Reynolds p.68)
2.What are same characteristics of  common computer  criminals.Include there objective.
1. Security of information technology is of utmost importance
Protect confidential data
2. Safeguard private customer and employee data
Protect against malicious acts of theft or disruption
Must be balanced against other business needs and issues
3. Number of IT-related security incidents is increasing around the world
4. Computer Emergency Response Team Coordination Center (CERT/CC)
Established in 1988 at the Software Engineering Institute (SEI)
Charged with
Coordinating communication among experts during computer security emergencies
Helping to prevent future incidents-To be sure, some computer criminals are mean and sinister types. But many more wear business suits, have university degrees, and appear to be pillars of their communities. Some are high school or university students. Others are middle-aged business executives. Some are mentally deranged, overtly hostile, or extremely committed to a cause, and they attack computers as a symbol. Others are ordinary people tempted by personal profit, revenge, challenge, advancement, or job security. No single profile captures the characteristics of a "typical" computer criminal, and many who fit the profile are not criminals at all.


3.What action must be taken in response to a security incidents.
- organizations learn how to respond to security incidents only after suffering attacks. By this time, incidents often become much more costly than needed. Proper incident response should be an integral part of your overall security policy and risk mitigation strategy.
There are clearly direct benefits in responding to security incidents. However, there might also be indirect financial benefits. For example, your insurance company might offer discounts if you can demonstrate that your organization is able to quickly and cost-effectively handle attacks. Or, if you are a service provider, a formal incident response plan might help win business, because it shows that you take seriously the process of good information security.

Firewall
 firewall is a set of related programs, located at a network gateway server, that protects the resources of a private network from users from other networks. (The term also implies the security policy that is used with the programs.) An enterprise with an intranet that allows its workers access to the wider Internet installs a firewall to prevent outsiders from accessing its own private data resources and for controlling what outside resources its own users have access to.
