  • PRTG Catches Network Issues Before They Cause Downtime Icon
    PRTG Catches Network Issues Before They Cause Downtime

    Threshold-based alerts flag problems early, so your team can act before users notice, not after.

    Reactive troubleshooting usually means hearing about a problem from frustrated users, not your monitoring tool. PRTG sets threshold-based alerts across devices, servers and applications, notifying your team by email, SMS or push the moment a metric crosses a set limit. That means catching a failing disk or overloaded server before it becomes an outage and getting time back from firefighting. Start a free trial and set your first alerts today.

    Sender & Receiver (Wireless Transfer)
    I have designed a wireless transfer software for home use called Sender & Receiver. This software is only compatible with Windows devices and can only be used within the local network (devices must be connected to the same WIFI). The software is very easy to set up and use, even for beginners. With this software, you can easily transfer files between your Windows devices without the need for installation. It is a convenient way to transfer files and share documents, photos, and other data on your home network. Overall, Sender & Receiver is a very convenient and practical wireless transfer tool that makes file sharing easier and more efficient. If you are confused about how to use this software, we will provide a tutorial video later to make it easier for you to get started.
