Cable Internet Types and Their Characteristics

When it comes to your Internet cable, as an inexperienced user you may not really care what is inside, what quality it has and so on, as long as you can get online. As a matter of fact, if you are not familiar with the industry of cable Internet plans, you may not even understand. Try asking some of the technical team representatives whenever they come hook you up or just fix something. You will be surprised to find out that sometimes, not even these representatives are able to give you precise information about what cable Internet you are about to get. However, for an experienced user, things are somehow different.

Each type of cable Internet comes with various advantages and disadvantages. Although you can't really make a decision or have options, some people who have technical knowledge prefer to know what exactly they got in their house. It may seem useless, but at least they know what kind of quality to expect. The unshielded twisted pair cable Internet is usually known as UTP. It is the most common one, especially in the twisted data networks. The UTP cables are often called Ethernet, after the most common standard. However, this is not always the most reliable one. It is usually used for the local loop of telephone networks and data networks, as a patch cable or a temporary network connection.

The foiled twisted pair (FTP) cable high-speed internet comes with the conductors covered in a screening exterior shield, to protect them against the external interferences. The shield also has the role of an earthing conductor. The screened unshielded twisted pair (SUTP) cable Internet is similar to the FTP one. There is however one big difference - the lace is stranded and there is no shield to cover all the pairs. In the same family, you can also count the screened shielded twisted pair (SSTP) cable Internet, which is a combination between the SUTP and the FTP types. It is screened with both a shield and a lace.

When it comes to expensive and private cable high-speed internet deals, you will most likely be provided with a shielded twisted pair (STP) cable high-sp Internet. Each pair is particularly covered into a screening shield, therefore this cable provides a very solid protection against any interferences. This ensures a solid connection, without the constant problems of losing it once in a while due to weather or anything alike. The shields also "play" as earthing conductors. The STP cable Internet is rarely implemented due to the very high prices. It is mostly used for large companies. If you think about such cable Internet plans for your home, you should also know this type of cable doesn't really have a flexibility.

Last, but not least, the screened shielded twisted pair cable Internet is similar to the STP one, but it brings in a few more protective features. This is even more rarely used, although it is by far the most superior type of cable Internet you can currently find on the market.

Different Types of Chat Rooms

The Internet is a medium, which offers different sources for keeping in touch with near and dear ones. The best mode of communication in present times is a chat room. There are numerous websites offering this service and allowing people to chat on particular topics. There are different chat forums available on the Internet, so you can choose one of them depending on your requirement.

- Themed Chat rooms: Most of the people use them for finding people, who have similar interests. Such chatting rooms would have titles, which may convey your interests. The theme of your chatting may vary depending on your choice such as sports, dating, religion, dance, politics and art. At the bottom of your profile's home page, there would be a drop down box, which may give an indication of your friends logged in these rooms. In this manner, you can easily chat with them on the desired topic and room list would indicate the title of your discussion.

- Teachers and Students: In recent times, life has become very complex and people in grave need of money, so they pursue distance learning courses. Teachers host classes online through these chat rooms and explain different topics to their students. In this manner, students get their lectures as well as notes in the comforts of their home.

- Dating: The most common purpose for getting into chat forums to date. People wish to get into relationships, so they enroll in these rooms. You just need to choose the title as dating and begin your quest to date. In the title, you need to add a title, which may indicate your interests. There are different chat rooms for divorcees, widowed and teenagers, so specify your requirements and interests. For instance, if you are a teenager, then you need to enroll in a chat forum, which has teenagers wishing to date.

IPv6 Addressing Types

IPv6 is joining IPv4 very soon because IPv4 is going to deplete somewhere within 2011. It's really important to start educating yourself about IPv6 as soon as possible so you can ride the wave just in the right time.

We all know the normal Unicast, Multicast and Broadcast addressing types of IPv4. The unicast and the multicast are still used by IPv6 while the latter is no longer used. IPv6 also has three address types as defined below:

Unicast Addresses: This is the one you already know, unicast addresses are assigned to hosts and router interfaces. Packets addressed to a unicast address are delivered to a single host or router interface defined with that address.

Multicast Addresses: These are addresses that represent various groups of IP devices: a message sent to a multicast address goes to all devices in the group. This is commonly used for applications like video conferencing.

Anycast Addresses: Anycast address identifies multiple interfaces. Packets destined to anycast address are delivered to the nearest interface identified by the address. The nearest is determined based on the network routing protocols and routing tables.Anycast addressing is used when a message must be sent to any member of a group, but does not need to be sent to them all. A common application for anycast addressing technique is load sharing.

The normal broadcast addressing of IPv4 is not existing in IPv6. Broadcast traffic of IPv4 is handled using multicast address type of IPv6.

In all cases, IPv6 addresses identify interfaces, not nodes. A node is identified by any unicast address assigned to any one of its interfaces.
