Wireless Networking - Router Vs Access Point

While planning for your wireless network you might be asking what is the difference between a router and an access point. You need to think of a router as more of a server because it performs many functions like a server. An access point only provides a portal for wireless client to connect to your existing LAN.

Routers can perform many functions. Routers can connect many different WLANs together acting like a traffic cop. Routers also act as a DHCP server. A DHCP server assigns dynamic IP address to your computer every time your computer starts up. If you don't have a DHCP server then you will have to assign each computer on your network a permanent IP address.

As I have said before your router can also act like a traffic cop. You can use a router to perform port forwarding to certain computers on your LAN. For example you can direct all internet traffic looking for your game server's port number to a specific computer on your LAN.

Wireless Networking - Router Vs Access Point

The ability to connect multiple computers to the internet is one of the main features of a router. The router is assigned one WAN IP address from your ISP. This IP address is called a public IP address that everyone on the internet can see. Because you have multiple computers connected to your router the router uses a protocol called NAT Network address translation NAT will assign the computers that are behind your routers IP address, private IP addresses. NAT acts as a firewall because computers on the internet cannot in theory even see your computers. They will only see the IP address of your router. NAT does block traffic from reaching your computers but it will not block Trojans from going out to the internet. That is why I do recommend installing a firewall on your LAN computers.

The role of an access point on a LAN is to give the wireless user a door way to enter. The more people that enter the door at the same time the slower they will go. 802.11b access points say they will give you a through put rate of 11mps but the actual rate is around 5MPS. 802.11g has a rating of 54mbps with an actual through put of 20mbps. The access points do have most of the same security features as a router such as WEP, WPA, 8021x and TKPI but they will not have the traffic cop functions like a router. Also the access points will not have NAT which would add an unnecessary layer to your network. To keep it simple access points just simulate plugging in your laptop to a port in the wall and that's it.A router is used on the border of you network to act as a traffic cop deciding who can come in and blocking those you want to keep out.

How to Trace a Cell Phone Location

New advances in technology have made it possible for anybody to trace a cell phone location.

These advances in technology designed to trace a cell phone location came about as a result of a number of recent events, including the events of September 11, 2001. Technological breakthroughs which have occurred since then include the inclusion of GPS technology in most mobile phones, and an improved ability to detect a phone's location based on signals from local transmission towers.

There are number services on the Internet which allow you to trace the location of a cell phone. They may differ in therms of interface and appearance, butthey are using the same data from the telecom companies.

How to Trace a Cell Phone Location

In the past the only way to gain access to the technology to trace a cell phone location was to buy equipment, and the use of this equipment was largely regulated to official organisations such as the police.

The way these services work is by gathering information from the telecom company that provides the cell phone service. this information includes the location of the cell phone as calculated by a combination of factors including the GPS as previously mentioned, and the distance to each of the nearest cellphone transmission masts. This is the same information which the police get.

There are wide range of reasons why you might want to trace a cell phone location, such as trying to find out where a friend or relative rates while you're out and about, keeping track of the location of a child, meeting up with friends, and trying to find shops and restaurants near you. Companies make use of these services in order to track their employees location, and also to provide security for employees when they are working in a remote location on their own. In the end, there are probably as many reasons as there are users.

The way GPS technology works in modern cell phones varies between the different cellphone networks, and with some operators it does not continuously transmit location. This means that when you want to trace a cell phone location, the information that you will be gathering is most likely collected from transmission tower locations.

The location of the phone will be tracked using triangulation - by taking 2 or more readings, it is possible to calculate where the signal is coming from by working out the triangle that fits the signal strengths. The 3rd point is the location of the phone.

However, when the person who has the phone has made an emergency call, this GPS transmission will always be sent. This is designed to ensure that the police can always track a cell phone location, in order to get help to people who need it.

The result of this design that the accuracy of the location which is provided by the service will be greater in areas which are more populated, and have more radio transmission masts, and will be lower in areas where there are very few radio masts, such is the wastelands, deserts, or un-populated areas of countryside. So, it is easier to track a cell phone location with a high level of accuracy in built up areas.

Nonetheless, most times you trace a cell phone location the information from the cell phone masts should be fine. After all, you do not need to know the person's location with a very great deal of accuracy for most purposes.

Free Reverse Cell Phone Lookup Websites - Do They Exist?

Is it really possible to run a free reverse cell phone lookup on the internet? Many of us have become disillusioned and frustrated in the past with websites which appear to offer free products or services online but in fact do not. Is this the case with cell phone lookups?

Firstly let us examine exactly what we mean by a phone number lookup. If you have in your possession a residential phone number but no idea who the number belongs to or what address it relates to you can use a "reverse lookup" service to find out those details. This can obviously be very useful in situations where you have lost contact with someone but still have a record of their phone number, or simply wish to verify who owns the number before mistakenly phoning the wrong number. There are many places you can perform such residential and business phone lookups online for free, including toll-free numbers.

However a problem arises when you need to run a reverse lookup on a cellular phone as the free directories do not contain any such numbers. Similarly they do not contain fax numbers as this information is only held by the carriers and telecommunications companies. Do these records exist, and are they free?

Free Reverse Cell Phone Lookup Websites - Do They Exist?

The good news is there are websites which claim to offer large numbers of cell phone numbers, but they are not free. These websites naturally have to pay for access to some of this information, and go to the considerable trouble of pulling all the various resources together in one place, and as a result you will be charged a small fee before you can access the lookup databases. However the fee is a one-off payment and with some websites you can run as many searches as you like once you have access, with others they offer a single lookup for a lower fee. The records they claim to offer include cell owner details, address history, carrier details, and the phone connection status. It is also worth noting that the databases offered by each company differ to some degree, but most include cell phones and often residential, business, toll-free, even pagers, and these websites say your searches are guaranteed legal and confidential.

In addition to reverse lookups there are also similar websites which offer access to information such as background checks and background reports, people finder databases, bankruptcies, liens, public records databases including births, deaths, marriages, divorces and adoptions, sex offender records, police records, and much more. These sites operate in the same way, offering access to specific types of information for a set fee, however it should be noted that you will not receive access to such information as part of your cell phone lookup site membership.

I have seen websites claiming to offer free cell lookups, but they always lead eventually to the paid sites in the end, even allowing people to search for free and then charging to view the results. It is the sad truth that the only place where you are likely to find detailed reverse cell records is within the legitimate paid directories. In conclusion, the answer is no, free cell phone lookups do not currently exist. However if you really want to access such records then I believe paying a small fee is a price worth paying.

Social Networking Disadvantages - This Could Save Your Life

Social networking disadvantages are mostly related to safety issues. Online social interaction has become a very popular activity online. Like most popular activities there is always a certain amount of danger involved. Social networking disadvantages will be minimized if you are cautious when you use it. Internet networking is the act of interacting and sharing information with others online. If you share the wrong information to the wrong person it can end in some dangerous results. If you are careful when giving out information and networking on social sites than you will most likely be safe and have a great time connecting with others.

Many social sites have upgraded their security to make it much safer for users. When social interaction sites first appeared on the market they were completely untested. Because of this there were many ways for predators and criminals to do harm to users. Hackers are always a concern with the majority of online sites. This is especially true for certain networking sites which promote tons of personal information about individuals. The social meeting sites have taken a lot of hits in the lack of security they provide. Young teens have been killed, forced to commit suicide, and abducted by child predators while using their social networking site. Although these incidents are horrible acts, they do not happen on a regular basis. Many such sites have raised their age limits and security to ensure better safety for networking users. Social networking disadvantages can be safely dodged if the sites are used properly.

Social networking disadvantages are lessened if you follow some common networking safety tips. The first tip to underrate social networking disadvantages is to utilize the privacy settings on your profile. One of the biggest dangers during socializing is having too much personal information available. You can use the privacy settings to screen incoming individuals and what they see of your profile. The second tip to reduce social networking disadvantages is to maintain your computer defenses. Always have virus protection and anti-virus on your computer. Networking sites can have a host of ads that contain virus code which can infect your computer.

Social Networking Disadvantages - This Could Save Your Life

The third tip to decrease social networking disadvantages is to review the network website's safety notifications, standards, policies, and learn how to report violating content. It can usually be found during the registration process. Make a copy so you have it handy if there is ever a security problem that you need to deal with. Another tip for curtailing social networking disadvantages is to remember to be cautious. Don't post it on your profile unless you want everyone in the world to see it.

Bad people are always lurking online waiting for someone innocent to prey on. People are not who they claim to be the majority of the time. Do not meet anyone from a social site unless you are sure that you know them or who they are. Even if you are comfortable with meeting that person still bring a friend and tell people about the meeting in case anything goes wrong. It is always better to be safe than sorry when it comes to social networking disadvantages.
