Data Management

A computer network, often simply referred to as a network, is a collection of hardware components and computers interconnected by communication channels that allow sharing of resources and information. Where at least one process in one device is able to send/receive data to/from at least one process residing in a remote device, then the two devices are said to be in a network.
Managed switches give you more control over your LAN traffic and offer advanced features to control that traffic. An unmanaged switch simply allows Ethernet devices to communicate with one another, such as a PC or network printer, and those are typically what we call “plug and play.”
The main difference between the 802.3af (PoE) and 802.3at (PoE+) standards is the maximum amount of power they provide over the Cat5 cabling. The maximum amount of power for the 802.3af (PoE) standard is 15.4 watts. The maximum for the 802.3at (PoE+) standard is 25.5 watts.
When the device is a switch, it is commonly called an end span (although IEEE 802.3af refers to it as endpoint). Otherwise, if it's an intermediary device between a non-poE capable switch and a PoE device, it's called a mid-span. An external Poe injector is a mid-span device./receive data to/from at least one process residing in a remote device, then the two devices are said to be in a network.

Data Recovery 
 

Accidental file deletion is common, and depending on the operating system, file system, and actions taken afterward, data may still be recoverable. Here's a breakdown of data recovery methods:
 

🔍 1. Check the Recycle Bin or Trash
 

• Windows: Look in the Recycle Bin.

• macOS: Check the Trash.

• If found, right-click and choose Restore.
   

💾 2. Use File History or Backup Tools
 

If you’ve set up automatic backups:

• Windows: Try File History, System Restore, or Backup and Restore.

• macOS: Use Time Machine.

• Linux: Look for tools like rsnapshot, Deja Dup, or custom backup scripts.
   

🛠️ 3. Use Data Recovery Software
 

These scan your drive for recoverable files:
 

• Free Tools:

  • Recuva (Windows)

  • PhotoRec (cross-platform)

  • TestDisk (for partition recovery, open source)

• Paid Tools:

  • EaseUS Data Recovery Wizard

  • Stellar Data Recovery

  • R-Studio

  • Disk Drill
     

⚠️ Stop using the drive immediately to avoid overwriting the deleted data.
 

💻 4. Command Line Recovery (Advanced)
 

• Windows: Use chkdsk, attrib, or PowerShell scripts.

• Linux:

  • extundelete (for ext3/ext4 file systems)

  • photorec or testdisk

• macOS: diskutil, fsck, and use recovery mode for disk repair.
   

🧰 5. Professional Data Recovery Services
 

If data is critical or drive is physically damaged:

• Send the drive to specialists (e.g., Ontrack, DriveSavers).

• They use cleanrooms and advanced tools to extract data.
   

🧾 Note: These services can be expensive but are often the last resort for irreplaceable data.
 

🧠 Best Practices to Avoid Data Loss
 

• Regularly back up data (cloud + local).

• Use file versioning (Google Drive, Dropbox, etc.).

• Be cautious with Shift + Delete or command-line deletions.
