What is MESSAGING -

Messaging is a method of communication between two people or organization. Messaging could be done using the power of Internet or through cell phones. Messaging software connects two people and facilitates them to communicate through text or voice or both of them. 

Two types of Messaging 

a) Asynchronous Messaging: 

The term “asynchronous messaging” means a method of communication between programs in which a program places a message on a message queue and leaves. It really does not bother how the message will be delivered. It is the delivery agent or the kind of infrastructure ensures delivery of message, even if the recipient is offline. For example, delivery of emails. 

b) Synchronous messaging: 

In this kind of communication sender and receiver both have to be in connectivity while transferring the message. For example, telephonic conversation. Hence, a program places a message in a message queue and then waits for a reply to its message before resuming further. Instant Messaging Instant messaging (IM) is a form of real-time communication between two or more people based on typed text or using audio or video. The message is conveyed via devices connected over a network. www  

www Most IM programs provide these features:  

Instant messages/Chat: sending and receiving text/notes with an online friend.  

Chat Rooms: a common platform where two or more than two people can communicate.  

Files/Web links/Videos/Images: can be shared over network.

Unified Messaging Unified Messaging (or UM) is combination of different media into one channel. A user can access information into different media using a single device.

It provides power to reach people almost anywhere, at any time and the flexibility to allow people to control when they can be reached. 

ISSUES WITH MESSAGING IM is increasing in popularity in both professional and personal applications. However, as with most of the things are Internet based, the increasing use of instant messaging has led to an associated increase in the number of security risks. 

Spamming Often in the email accounts one receives lot of unwanted mails which includes threats, promotional mails and so on. These messages are called Spam. There are two kinds of spams, mail lists and individual mails. Often users subscribe mail lists where lots of promotional materials are posted in bulk. These materials are of generic nature. There is another type of spamming where individual users are targeted for example, individual messages from unknown for illegal business or receipt of some unknown prize. Almost all the service providers have mechanism for filtering such messages based on the conte 

Privacy -Many Email service providers have their own privacy policies. Most of the free web based email services have financial dependency on advertisers and in return they share user information such as their email address information with advertisers. Also, details of the communication can be shared with government agencies on demand. Thus, one must be aware of the privacy policies of an email service provider before going for their services. 

Security Email /Instant messaging account are vulnerable to hijacking or spoofing. Spoofing is a phenomenon where an attacker hijacks another user’s email/IM account and impersonates as user with others. Things apart the information exchanged over network can also be read over network by a third party. Hence, it is important to ensure information exchange. 

There are several ways which have been devised to overcome all these problems which are enlisted below:

 1) One of the best ways to secure the information being transmitted along an IM network is to encrypt it. 

2) Keeping message logs for tracing any kind of mischief. 

3) If file transfer via the instant messaging network is not required, then an instant messaging system that does not allow for files to be transferred should be utilised. 

Electronic Mail is one of the most prominent uses of networked communication technology. Better known as email, this is one of the most widely used forms of communication today. Electronic mail (email) has many advantages over other forms of communication: it is easy to use, free of charge, fast, and delivers information in a digital format. With suitable encoding methods, email can be used to send any kind of computer file, including pictures, sounds, programs, and movies. Email started in 1965 as a way for multiple users of a time-sharing mainframe computer to communicate among themselves. ARPANET had a significant role in popularising email. The foundation for today’s global Internet email service was created in the early ARPANET
