2.2 Identify tools and software used with personal computer components and their purposes  
  2.2.1 Identify hardware tools and their purpose  

A toolkit should contain all of the tools necessary to complete hardware repairs. As you gain experience, you will learn which tools to have available for different types of jobs. Hardware tools are grouped into these four categories:

  • ESD tools
  • Hand tools
  • Cleaning tools
  • Diagnostic tools

ESD Tools
There are two ESD tools: the antistatic wrist strap and the antistatic mat. The antistatic wrist strap protects computer equipment when grounded to a computer chassis. The antistatic mat protects computer equipment by preventing static electricity from accumulating on the hardware or on the technician. Click each of the items in Figure 1 for more information on ESD tools.

Hand Tools
Most tools used in the computer assembly process are small hand tools. They are available individually or as part of a computer repair toolkit. Toolkits range widely in size, quality, and price. Click each of the items in Figure 2 for more information on hand tools.

Cleaning Tools
Having the appropriate cleaning tools is essential when maintaining or repairing computers. Using these tools ensures that computer components are not damaged during cleaning. Click each of the items in Figure 3 for more information on cleaning tools.

Diagnostic Tools
A digital multimeter and a loopback adapter are used to test hardware. Click each of the items in Figure 4 for more information on diagnostic tools.
