Affiliated with humidity is water, and sensors are usually electronic, so we know that much. There are two types, an analog and digital sensor. For an mechanical one, three components are necessary. First, the exterior is made out plastic. Secondly, there is a small capacitor in the interior made of film-like glass or ceramics. The interior is insulated by a polymer. For a digital sensor, microchips are used instead of a capacitor and polymer. It has a biological synthesis which is perfect for absorbing and emitting. This affects the analog, making it intellectually simpler. The amount of water vapor in the air, is then absorbed by the polymeric material. This polymer then emits water based on the relative water vapors. This changes the electric scale of the capacitor which shifts the analog. Some digital sensor are in essence a data Logger, and others are converters. There is also a tiny analogin between the various chips. The Data Logger chips, through an analog, digitalizes the humidity. This information is then transferred to a chip which displays the information.

An analog contains a large amount of polymer so when the polymer wears away the entire balance changes. Also, since there are many
components a calibration process is necessary. To configure many units together through trial and error is strenuous. Another problem is the electricity balance in the capacitor. This leads to increased spending on electronics, but that also means less money. There are many benefits to the digital style. The interior does not consist of polymer, but rather it is used as a protective encasement. This allows for efficiency without collaboration. In addition to the longevity of the collaboration it is easily replaceable. In the analog form, polymer not only has to be replaced, it also has to be collaborated.

In our daily life, we have embedded in our technology a humidity sensor. Our air condition needs it to determine how much the temperature needs to be lowered. Modern Dryers use them to stop the machine at the proper time. Cars, our daily transportation, have one located in the exhaust manifold to control in-car temperature. Cutting edge jets and shuttles use them to control oxygen and temperature levels. Now with advance technology we have even learned how to determine which crops a block of soil can sustain. In a world with many new concepts and ideas, however a humidity sensor is part of technology and necessary to maintain the infrastructure of our life.

Although the term ‘computer security’ is used a lot, the content of a computer is actually vulnerable to only a few risks unless the computer is connected to others on a network. As the use of computer networks (especially the Internet) has increased dramatically during the past few years, the term computer security is now used to describe issues referring to the networked use of computers and their resources. The major technical areas of computer security are confidentiality, integrity and authentication/availability.

- Confidentiality, also known as secrecy or privacy, means that the information you own cannot be accessed by unauthorized parties. Breaches of confidentiality range from the embarrassing to the disastrous.

- Integrity means that your information is protected against unauthorized changes that are undetectable to authorized users. The integrity of databases and other resources are usually compromised through hacking.

- Authentication means that an user is who he claims to be.

- Availability means that the resources are accessible by authorized parties. Examples of availability attacks are the ‘denial of service’ attacks.

Other important things that the computer security professionals are concerned about are access control and nonrepudiation. Access control refer not only to the fact that users can only access the resources and services they are entitled to, but also to the fact that they can’t be denied to access the resources they legitimately expect. Nonrepudiation means that a person who sends a message cannot deny he sent it and vice versa.

In addition to these technical aspects, the concept of computer security is very large. Computer security’s roots are drawn from disciplines like ethics and risk analysis and the major topics that are concerning it are computer crime (tries to prevent, detect and remedy attacks) and identity/anonymity in cyberspace.

Although confidentiality, integrity and authenticity are the most important things when it comes to computer security in general, for everyday internet users, privacy is the most important one, because many people think that they have nothing to hide or the information they give doesn’t seem sensitive when they register with an internet service/site. But remember that, on the internet, information is very easily shared among companies and small pieces of related information from different sources can be linked together to form something alot more complex about a person. Because of this, nowadays, the ability to maintain control over what information is collected about them, who may use it and how it can be used is extremely important.
