Disadvantages of Internet
Internet is a medium that can be used for multiple purposes such as entertainment, infotainment and along with this it is a powerful business tool in the current age. Where internet is a big blessing it has a number of disadvantages too. Though internet in countless ways has facilitated our lives of ordinary men but the negativity of the Internet are also making us to think about our actions.
But, as a regular internet user we must keep in mind that it holds a number of threats when we use it. So, it should be used with a little care. These threats may harm us and may become a cause of misuse of our personal data. Here are few worth-noting disadvantages of Internet that every user should keep in mind.
The very common problem on internet is of spam emails. Almost every now and then we see some unknown emails of unknown subjects from unknown users contaminating our inbox. Large distributions of not-asked-for messages block the data streams on internet. Though, spam filters are provided by the mail hosting websites in order to filter out good emails from the bad ones, but even though the international standards has declared it illegal.
Second important threat that we face is from the hackers who steal our personal information such as, name, address, credit card numbers, etc and use it against us. People on internet take such information from you by building trust and then your data is used for frauds. This is a widespread and hard to control malpractice over internet and you must ensure that you are providing all the sensitive information only to reliable websites otherwise you may lose your hard earned buck at the hands of any swindler.
Another bad side of internet lies in websites laden with adult content and such websites are widely available over internet and if accessed by your kids they may pick wrong lesson out of it and they have negative impact for their mental health. Internet does not provide any bar on Pornography yet so you have to be extra careful by putting software protections on in order to control the adult content where there kids are accessing internet.
No matter what you try, everyone can become addition to internet, consequently our precious life gets wasted on nothing. Internet is full of information, and multimedia content, when one gets on the internet, he/she gets dragged by different content shown on web pages, followed by further web browsing by clicking the links, icons, advertisements displayed on the websites. This addiction is dangerous especially for kids and must be taken care of.

Cable internet service
Cable is one of many kinds of Broadband Internet services, offering very high speed data transfer rates. Cable internet downstream speed comes around 100 Mbit/sec and between 128 Kbps and 768 Kbps for upstream. While Cable Internet is faster than DSL Internet, it often gives lesser speed for technical reasons. One of the main reasons for this is that your neighborhood uses the Internet simultaneously, hence sharing your Internet bandwidth.
There is another form of Cable Internet services, called Asymmetric Cable that provides equal bandwidth for both uploading and downloading but due to the fact that downloading is the main requirement of majority of the users, they do not prefer this form of Cable Internet service.
With cable modem, it is very convenient for customers that they can get all - TV, Telephone and Internet from a single provider and get a combined bill for all services (unless more than one providers are used for different services)
DSL stands for Digital Subscriber Line. It is an all-time connected Internet, which does not require you to dial to the Internet Service provider.
In a DSL connection, the download speed is relatively lesser than the upload speed. However the good thing is that your Internet connection is not shared with your neighborhood giving you maximum speed all the times. Giving many PCs access to Internet with one DSL connection is practically possible. Multiple Computers whether in home or office can easily be given Internet access with just a single DSL connection.
The downstream rate you can get varies from 1 to 170 Mbit/s. New technologies are entering the markets and the speed of DSL Internet is also increasing as service providers periodically upgrade their network equipment with latest technologies.
DSL connects you to Internet through a regular telephone line and brings you an extra benefit of using telephone on the same line whilst internet connected. Customers can stay logged on to Internet for indefinitely period if they want but this creates a minor security risk because PC will use same IP address for long time giving hacker higher chance to attack your PC! However, DSL provides overall reasonably safe Internet access.
ADSL or symmetric Digital Subscribers Line, although much faster than DSL, it can generally be used only over short distances - usually within 4 kilometers. The user must live within a certain distance of the nearest telephone exchange to receive best speeds.
ADSL connections, unlike DSL, offer higher download speeds than upload speeds.
The maximum speed for ADSL connections is 18MB. ADSL, like DSL, operates over a normal telephone line. Voice calls can still be made even when internet is in use. ADSL often presents some technical problems during its setup. Therefore installing of appropriate frequency filters at the customer's premises is necessary to avoid possible interferences with the voice service. ADSL2 and ADSL2+ are starting soon. ADSL 2 will provide download speeds of up to 24Mbps, while ADSL 2+ will offer twice of this.
Because ADSL requires its users to be located within 4 kilometer of its base, Â it has comparatively much less users than of any other form of high-speed Internet.
SDSL is an acronym for Symmetric Digital Subscriber Line. Basically, similar to DSL with only exception to the bandwidth for up and downstream. Unlike, DSL that has less download speed than upload, SDSL is symmetric that means you can get equal bandwidth for both up and down streams.
Although a fast type of Internet, which gives up to 4 MBit/Sec speeds will still vary depending on your distance from the Internet service provider. SDSL connection best suits cooperate users because it offers consistent high-speed internet to transfer files to vendors, clients, customers, different office departments, etc.
WiMax stands for Worldwide Interoperability for Microwave Access. It is a technology to deliver cost-effective and high-speed internet over long distances without using wires. To receive Internet using WiMax, two types of signal receiving equipment is available outdoor and indoor. Indoor devices are obviously convenient since these are very small in size but the subscriber must be significantly closer to WiMax base to avoid any radio losses and possible temporary disconnections.
WiMax Internet is connected at all times - there is no need to dial to the service provider. WiMax offers internet connections via Wi-Max or Wi-fi Hotspots. Hotspot is a place (e.g. a cafe, airport, home, hotel, park, etc) where Internet is wirelessly available. Public can freely use Internet by connecting their PCs to the hotspots. There many websites containing list of Hotspots. This is among the good ones. http://hotspotr.com/wifi
This technology provides up to 72 Mbit/s symmetric speeds to the radius of about 40 miles.
If you are traveling to a remote place, you will not have any of the above described internet connections available. At such a place, you may use your mobile phone's data service to connect to the internet. Nowadays, mobile internet has become very fast, offering 3G and 3.5G speed, which is approx 2-10 Mb/s. 4G, a much faster version is also available, offering speeds between 5MB and 100MB.
It's the 3D Internet Era. 3D technology has tremendously changed the way people see and navigate the internet. Today 3D technology is greatly preferred by people because of its real and crystal clear experience. One reason for its popularity is that it is quite different from traditional two dimensional experiences. The demand for 3D worlds depends on the level of captivation that the programs offer to consumers and vendors. 3D animations, 3D games, 3D internet and 3D TV are some important examples of this technology. Conversely, the other side of picture is that 3D technologies especially 3D internet can also lead to increased cyber crime ratio, as long as 3D internet is becoming increasing popular today.
3D Internet Technology and Components
Though the technology and components used for 3D internet are same as used in traditional internet also it interacts with the same servers and search engines. But being more social 3D internet is different from traditional 2D internet. The wonderful thing about 3D internet is that participants learn as much from each other as from talking to any official source of information. 3D internet search is also so advanced as it opens a vast array of possibilities when it comes to search and browse data. Through 3D internet multi users can read the same documents. You connect organically with other people that share your interests and access the same service as other use. People can also watch online 3D movies via internet with no buffering time. 3D internet also offers other facilities like virtual meetings, support groups, academics, training chats and shopping.
3D Internet Features
One of the best features of 3D internet is that it also supports 3D internet TV. Now Sony is thinking to launch new technology for 3D TV that is 3D internet TV and HDTV 3D internet TV Wi-Fi. In such TVs internet connectivity will be built up in TV via Wi-Fi. The picture and graphic quality will also be tremendously improved along with a lot of TV channels that is building in internet connectivity with 3D TV, to improve quality and to increase number of channels that user may access. With Sony internet 3D TV, it will also be possible to enjoy other services on TV such as Skype.
Under the light of this discussion, it can be said that soon 3D technology will become the necessary part of our routines. Along with TV and internet we anticipate its corporation in other fields. On the other hand, it is very necessary to use it in proficient way to save important time and money resources.
