File Sharing Goes Mobile

January 30th, 2010



Advances in communications and technology have brought with it an off-shoot phenomenon that has greatly impacted the way individuals and businesses connect and deal with each other. File Sharing, which usually follows the Peer-to-Peer (P2P) model, has made it possible for people to connect in an instant. It involves an exchange of files between two users: an uploader providing the file and a downloader, who receives the file. The files are usually stored and served by the personal computers of the users.

Whereas before it would take days for individuals from across the globe to share photos, documents, videos and music, file sharing has bridged that gap of time and distance. Its impact is probably most felt in the music and entertainment industry wherein file sharing has made it possible for fans to listen and watch the latest music and movie releases in a span of seconds! As soon as the upload is finished, fans can easily download the file and be instantly updated with the latest events in the music and entertainment industry.

This wave was started by Napster, a file sharing service that paved the way for other P2P file sharing programs which are now used for many of the same reasons and can download music, pictures, and other files. The popularity and repercussions of the first Napster have made it a legendary icon in the computer and entertainment fields.

Napster was only just the beginning. Its pioneering effort in the file sharing phenomenon brought about the rise of more advanced P2P file sharing programs.

Kazaa, for one, is commonly used to exchange mp3 files over the internet. It uses the FastTrack protocol and enables users to exchange other file types as well. Videos, documents, and even software applications were made readily available to downloaders. However, Kazaa also saw its decline as it found itself the target of many copyright-related lawsuits. In addition, it has also become infamous due to the large number of viruses, worms, and Trojans that it has been known to support and help spread.

iMesh is a social network that also operates as a file sharing system. It has its own protocols for file transfer, and it was also the first to introduce the concept of swarming; that is, one user can download a single file from many different sources, effectively breaking the file down and increasing the speed of one’s download.

P2P sharing programs like iMesh has brought with it the rise of Limewire, probably the most commonly used P2P application for downloading mp3s and videos. LimeWire is a P2P client for the Java Platform, which uses the Gnutella network to locate files as well as share files. Although a free software, Limewire also offers a PRO version which differs from the Basic Version in a number of respects; the most highlighted being its “Turbo Charged” downloads as it allows downloads to come simultaneously from 10 peers rather than only 8.

Swarming eventually led to the development of BitTorrent, the latest rage in File Sharing. Also P2P in nature, BitTorrent users connect to each other to send and receive portions of the file. What sets BitTorrent apart from its other file sharing counterparts is that there is a central server (a tracker) which coordinates the action of all peers. The tracker only manages connections but it does not have any knowledge of the contents of the files being distributed; therefore, a large number of users can be supported with relatively limited tracker bandwidth. The key philosophy behind BitTorrent is that users upload at the same time they are downloading. In this manner, network bandwidth is utilized as efficiently as possible. BitTorrent is designed to work better as the number of people interested in a certain file increases. BitTorrent is ideal for downloading the latest movies, discographies and software applications.

File Sharing and the Mobile Web

Indeed, file sharing has become quite the phenomenon that it has even carried over to the mobile web. Mobilemo, a mobile web site builder, is among the few mobile web hosting platforms that introduces file sharing features for mobile phones. People from across the globe now find it easier to connect and share photos, music, videos and files with friends, family and business partners. Mobilemo facilitates file sharing by enabling its members to upload their files through the internet and letting their friends download these files through mobile phones at any given time and at any given place. With Mobilemo’s file sharing feature, connecting with friends, promoting creative freedom, and keeping up-to-date with the latest trends and happenings have never been this easy!

Although still not as advanced as the file sharing programs made available on the Internet, Mobile File Sharing offers mobile phone users the instant convenience of sharing and downloading their files on-the-go. Businesses get to present their latest line of products to clients and partners without having to log into a PC. Mobile File Sharing also celebrates creative self expression-artists and musicians are given another venue to showcase their latest artworks and musical compositions through mobile phones! Fans get to download their favorite songs, videos and artworks as soon as it is uploaded! Although not yet as highly developed as its Internet file sharing counterpart, the future is definitely looking good for Mobile File Sharing!

Mobile Phones – The Perfect Spying Device?

November 15th, 2009



As mobile phones are becoming increasingly more advanced, consumers are making use of being able to access their email or bank accounts on the move. With many of today’s mobile phones coming closer to miniature computers than traditional phones the need for tougher security has never been stronger.

There is an alarming amount of viruses and Trojans that are infecting phones, which is why a number of anti-virus companies are now making software to protect people’s phones as well as their personal computers.

Even though the threat of mobile viruses is larger than many are aware, it pales in comparison to that of mobile spying tools. Such tools are usually invisible once installed and are able to report every phone call, text message and email amongst other things.

A popular example of such software is available to download from a website based in Bangkok. Using this software a user is able to install the software on someone else’s phone, which then becomes invisible to the main user. They are then able to log into the software’s website and view reports of all calls, text messages and emails sent and received on the phone.

Even more frightening, if the phone is equipped with GPS then the remote user is able to track the phones exact location, nearly anywhere on the planet. Also, it is possible to listen into the users calls, and remotely activate the phones microphone and listen into non-call activity.

Thankfully, the software cannot be installed remotely nor is it self replicating, therefore a user must have access to your phone before they are able to install the software.

Also, even though the software is not classed as a virus, it is considered by many security companies to be spyware and is therefore picked up by their spyware detectors.

What is SMS?

October 11th, 2009



What is SMS?

SMS, also known as short messaging service, is the rage in Europe and parts of Asia. Gradually SMS is gaining momentum in the US as a low cost messaging solution. SMS is defined as text messages, up to 160 characters in length, sent to mobile phones. In recent months SMS has become synonymous with any text message sent to a cell phone.

Benefits to SMS

SMS is a convenient, cost effective alternative to voice messaging. SMS popularity has grown as a result of:

1.) Cost – SMS is less expensive then the airtime used for voice calls or web access.

2.) Non-intrusive – messages are received in a discrete fashion and do not interrupt an individual if they are in the middle of a meeting

3.) Integration Capabilities – many software programs can be set up to send text alerts to mobile phones when urgent conditions exist.

Short Messaging Explained

Short messages can originate from other phones, personal computers or the Internet. Consumers and businesses alike use SMS for remote communication, allowing for staff to be mobile and stay in touch with those who matter.

Who Offers SMS?

Today nearly all the cellular carriers provide some level of SMS or text messaging capabilities. Cost and features vary, with carriers offering a variety of packages to suit individual or business needs. Typically there are three options that carriers provide:

1.) Free of Charge – text messaging is included as part of a select plan.

2.) Per Message Fee – users are charged per message.

3.) Monthly Fee – a set monthly fee includes a specified number of text messages.

How Do You Send SMS Messages?

Messages can be sent a variety of ways, depending on the service provider that you use.

SMS Software

The most popular way to send text messages is using software. When using software there is no cost associated with the sending of messages. Depending on the carrier that you are sending to messages can be sent any number of ways. Different carriers use different standards or protocols, the common protocols supported by most software is: via modem (TAP, UCP), the Internet ((SNPP, WCTP) and via email (SMTP). Software is flexible and often allows for group or scheduled messaging. Another benefit to software is the ability to automate processes, sending SMS alerts when specific conditions exist often without the need for human interaction.

Public SMS Gateway

Public gateways are often referred to as SMSC or SMS centers. The centers typically run a robust software application (like advanced versions of those mentioned above) and subscribe to a large database that allows for the messages to be routed to the appropriate carriers using the appropriate settings. When using an SMSC the sender incurs a per message charge. Cost will vary depending on the SMSC used to send the message but its not uncommon for it to cost .05 per message.

Phone to Phone

Many of the new mobile phones and those on the GSM network allow for messages to be sent from phone to phone. The keypads are rudimentary and not conducive for long messages but are effective when time is an issue and a concise message is needed.

Win for everyone

SMS messaging has been helpful to consumers and carriers, as the cost of sending and delivering SMS messages is relatively low. SMS messages have proven to be a lucrative revenue stream for struggling telecom providers.

The Future of SMS

SMS will continue to grow as part of the telecom industry. As software processes become more complex users will exploit text messaging capabilities in order to allow for additional mobility in the workplace.
