Wireless Networking
The term wireless networking is a technology that enables two or more computers to communicate using standard network protocols without network cabling. The industry standard mainly used for wireless networking is IEEE (Institute of Electrical and Electronic Engineers) 802.11. What this standard is could be described as a wireless network with hardware that requires the use of technology, which deals with radio frequencies as well as data transmission.
There are two kinds of wireless networks, Ad-Hoc (Peer to Peer), or access point (base station). Ad-Hoc (Peer to Peer) consists of a number of computers each equipped with a wireless networking interface card. Each computer can communicate to other wireless enabled computers. They can share files and printers, but may not be able access wired LAN resources unless one computer acts as a bridge to connect to a wired LAN.
Access points (base stations) can be hardware based or software based. The hardware based access point is a separate component connected to a wired Ethernet network and or server via an interface card. Software based access points can be a computer operating with software installed and is connected to a wired Ethernet network with an interface card. The benefits of software access points are there are fewer components, easier to set up, more cost effective, and have more built in features.
Many manufacturers of wireless equipment can function with each other using IEEE 802.11 standards. There are two different methods for wireless communication, Frequency Hopping (FH) and Direct Sequence Spread Spectrum (DSSS or DS). It is important to check which of these two methods are being used because they can not work together. The latest version of the IEEE 802.11 standard is 11 mbps and 5.5 mbps (mega bits per second), with support for the older standard of one mbps and two mbps speeds. This new standard only covers Direct Sequence Spread Spectrum, not Frequency Hopping types. It is expected that the price of wireless networking interface cards to become inexpensive like the Ethernet cards.
If your computer is connected to a wireless LAN, you can communicate to a wired LAN. You would need some sort of bridge between the wired and wireless LAN. You would need hardware or software based access point. Hardware access points are available with various types of network interfaces such a...

...d, much less decoded, by simple scanners, short wave receivers etc. You can gain access with specialist equipment. You can protect your data with a function built into 802.11 called WEP (Wired Equivalent Privacy), a form of encryption, which provides comparable privacy as the wired network. Traditional Virtual Private Networking (VPN) will work over wireless networks in the same way as traditional wired networks.
IEEE 802.11 standard makes it possible to connect anything that has support for instance PDA’s, cell phones, cars, appliances, computers, body suits, electronic watches, etc. This technology is growing fast and soon everything will be communicating with each other. There are many uses of this technology and can be implemented in a number of different ways.
Security of data can be minimized using WEP and VPN. The technology is not that old and like most electronics and software, it too will evolve and change over time. More standards and uses are being developed. Technology is only limited by our dreams.

The United States has always had criminals walking around the streets or locked up in an everyday life situation. Crimes are committed everyday by young children, adults, seniors, or any kind of man or woman that may look like a bad influence or others that look like innocent people walking down the streets who have never committed a crime before. Juveniles ages 7-15 should not be sentenced to life without parole for crimes they commit because it would not be fair for them to spend the rest of their lives in jail for committing a mistake. Reasons can be found on why juveniles should be left inside a cell and arguments can build up if people disagree with one another. Some adults commit crimes and are left with freedom after a satisfied amount
There has always been controversies as to whether juvenile criminals should be tried as adults or not. Over the years more and more teenagers have been involved in committing crimes. In some cases the juries have been too rough on the teens. Trying teens as adults can have a both positive and negative views. For example, teens that are detained can provide information about other crimes, can have an impact in social conditions, and serve as experience; however, it can be negative because teens are still not mature enough for that experience, they are exposed to adult criminals; and they will lose out on getting an education.
When it comes to individuals committing serious or harsh crimes, a sentence should match the crime that was committed. However, say this individual is under the age of 18. Should that make a difference in the amount of time they should serve, or should they serve any time at all? Based on age, states or locations, crimes committed and many other factors, we will discuss whether or not juveniles should be tried as adults. There are many arguments back and forth on whether or not a juvenile should be tried as an adult for their crimes. The two main reasons that are prosed for juveniles being tried as adults are that 1) the sentence should be proportional to their crime no matter the age and 2) the harsher or severe punishment will help lower juvenile crime rates. However, according to research juvenile crime rates have increased and the deterrent effects are minimal or almost non-existent. According to research and studies, a child’s brain does not fully develop until the age of 25. With this in mind, it brings up
My first reason juvenile offenders should be put in jail is because it will bring down the amount of crimes committed by young kids. My evidence comes from a website called Child Trends. It says that treating juveniles as adults helps with crime rates. According to Le Monde, in 2008 80% of those in juvenile facilities reoffend. Le Monde also says that 75% of
With the current crime rates on the rise, the justice system is trying to reduce adult criminals by strictly prosecuting juvenile offenders as adults. Many people believe that in doing so will scare the criminals back on the straight path and help to lower the crime rate. Trying a juvenile as an adult will have no effect on reducing crimes, corrective behaviors, or a juvenile’s comprehension ability.
If they are tried as adults, they can set an example for other teenagers who are thinking about committing a crime for any reason. For example, In “On Punishment and Teen Killers,” Jenkins said that her younger sister who was pregnant and her husband were shot by a teenager for no reason except of the fact that he wanted to know what it feels to shoot somebody. Despite of serving three life sentences in prison which some people may disagree with because of his age, it is hard to believe how dangerous he could be to other people if some day he was released to live among us. Although it is hard to think that someone could do this awful crime at certain age, it still doesn’t change the fact that he did it and caused a huge pain and sorrow to their family that could affect them for years. In my opinion, a crime is a crime and for that reason Juveniles who commit violent crimes should be tried in the same way as adults. Also, the decline that occurred in most of the U.S. during the past decade coincides with the fact that most states now permit minors to be tried as adults for violent
As human being we all do things that can lead us to great consequences. Our media has created a big picture of criminals, as a big horrible factor that would lead to destruction. The media have come to a conclusion, that just because we do things that are against the law, we are the bad people and need to lock away. Many people have discussed this very important topic, but I certainly believe Juvenile offenders should not be tried as an adult.
The rapid progress of embedded MEMS (micro-sensing technologies) and wireless communication has made wireless sensor networks possible. Such an environment may have many wireless nodes which are inexpensive; each node is capable of collecting, storing and processing environmental data, and communicating with neighboring nodes. These sensors are connected with wires in the past but tod...
The propose research will address a problem confronting many two year institutions in the present-day (i.e. how to best plan, design, and implement WLAN technologies). While WLAN technologies offer the benefits of mobility, reduced installation time, and decreased cost, many challenges must be met by institutions deploying them (Geier, 2005). These issues are related to security, speed, interoperability, and equipment selection, ease of use, reliability, signal interference, installation, and health risks.
Juvenile offenders should not be tried as adults because there are differences between a teenager and adult. A teenager is not mature as an adult. Some teenagers are capable to change their behavior and are capable to recognize their own mistakes. It is a huge mistake for juveniles offenders to be tried as adults and send them to adult court and prison . There are many factors why they should not be tried as adult.
Wireless technology has come from the basics of cellular usage to sensors in the medical field. Wires are now a thing of the past in today’s world with technology forever revitalizing. Wi-Fi (Wireless Network) or 802.11 networking is a phenomenal way of providing wireless Internet at a low cost. Using radio waves, a wireless network connects a PC, mobile phone or just about anything that connects to the internet wirelessly via a router.
Local Area Networks also called LANs have been a major player in industrialization of computers. In the past 20 or so years the worlds industry has be invaded with new computer technology. It has made such an impact on the way we do business that it has become essential with an ever-growing need for improvement. LANs give an employer the ability to share information between computers with a simple relatively inexpensive system of network cards and software. It also lets the user or users share hardware such as Printers and scanners. The speed of access between the computers is lighting fast because the data has a short distance to cover. In most cases a LAN only occupies one or a group of buildings located next to each other. For larger area need there are several other types of networks such as the Internet.
In conclusion, juveniles should be tried as adults as they are capable of thinking and acting like an adult, and therefore need to be punished accordingly. They are punished to mildly for the severity of the crimes they commit. Therefore, there must need to be more intervention to prevent these juveniles from committing crimes, and give them the future they need to grow to their full
Introduction: This is a 21th century, technology is the most important and improved thing of the human life. It makes life easier and faster. Development of faster sophisticated technology we have better and fast life. So all we are connect each other by computer network. There are two different way of network: Wired and wireless. Now day we can found network almost everywhere. Home, business, public place, Airport, Planes, hospitals, school, train everywhere we can found networking. Therefore, almost every sector of the economy that has affected by wired and wireless technology. Wired network and wireless protect both has security, But in general wireless network is less secure than wired networks. For proper security AP (access point) and its antenna should be right position. Also add a wireless access point or use a wireless router we can connect to network wirelessly. AS we using more and more of devices (smart phones, tablet and computers) rely on wireless networking, we have to improve our network security too.
