Detailed Tool Descriptions

1. **ESD Tools: **

   • Function: Prevent electrostatic discharge (ESD) which could damage computer systems.
   • Examples: Anti-static wrist strap (to ground technician), Anti-static mat (prevent build-up of static electricity)

2. Hand Tools:

   • Uses: Varied tasks such as fastening/loosening screws, cutting wires, connecting wires, and stripping wires.
   • Examples:
     • Screwdriver: for screws
     • Wire cutter: for cutting wires
     • Flashlight: for inadequate lighting
     • Soldering iron: for connecting electrical components
     • Wire stripper: for removing insulation from wires
     • Crimping tool: for joining RJ45 connectors to UTP cables

3. Cleaning Tools:

   • Focus: Maintaining cleanliness and preventing damage to computer systems
   • Examples:
     • Cable ties: organizing cables
     • Lint-free cloth: cleaning dirt and stains without causing ESD or scratches

4. Diagnostic Tools:

   • Purpose: Testing the functionality of LAN cables
   • Example: LAN tester (checks for faults/missing connections)
   • Process: Attaching LAN cable to tester, checking light functions, recrimping/replacement as needed
