When it comes to similarity, Local Area Network (LAN) messenger and Instant Messaging (IM) has a lot in common. Both platforms are used to deliver messages in real-time through the connectivity of the internet. LAN messenger works for local area network or within a group, business, organization’s network while Instant Messaging (IM) is used publicly meaning anyone can send a message to everyone who has IM installed to their computers and mobile phones.

Local Area Network

LAN messenger is a free and an open source for people who want to send message in cross-platform applications, it does not have any server, but it can operate very well with its key features that include notifications, message logging and file transfer which can be installed for Windows, Mac, and Linux operating systems and all three operating systems can receive and send and can also communicate smoothly.

You might be confused right now that LAN messenger and IM are technically the same, but you are completely wrong. In fact, people who want to have a secure and safe conversation or messaging often choose LAN messenger rather than Instant Messaging (IM) and it is often recommended by professionals because of its private and secure connection even for offline messaging.

You may read some advantages that you can find in Instant Messaging, but these are all the advantages and benefits of LAN messenger.

  • Internal Mailing
  • Favorite Users list
  • Conversation History
  • Voice Calls
  • Video Calls
  • Notes
  • Reminders
  • Off-the-record (OTR) or incognito messaging
  • Instant chat
  • Group conversation
  • Announcements or events
  • File Transfer
  • Remote desktop

One of the main advantages of LAN messenger over Instant Messaging (IM) is that it does not have a dedicated server, all it needs is an installer and a network within the users. What makes having a server disadvantageous is that it has regular maintenance and can encounter system interruption that bogs down the function of the messenger. However, there are also LAN messengers that runs through servers, but these are found in large businesses and organizations.

In terms of security, everything that you typed, sent and did in the chat box of a LAN messenger is encrypted. It has secure messaging to keep the user’s conversation history private. All the messages sent, received in LAN messengers are protected by an Advanced Encryption Standard (AES) encryption that also has RSA Data Security. RSA stands for Rivest, Shamir, and Adelman who developed this encryption data security program making it very private and safe for its users.

Instant messaging meanwhile maybe very good when it comes to real-time replies but since it is accessed publicly, you can’t assume who are the people using it on the other side, they could either send you viruses or they have other malicious intent.

In the end, whether you are using LAN messenger or Instant Messaging (IM), it depends on how you use it correctly.
