CompTIA Network+ Certification Exam Objectives
It is difficult for a recruiter or employer to evaluate if an individual is
a competent IT (Information Technology) professional because the technology in
the IT field is complex. For this reason CompTIA
(Computing Technology Industry Association) has defined specific skills and
knowledge that an IT professional must have, and has developed certifications
that attest to the individual's competency.
If an individual holds a CompTIA certification, the recruiter or employer
can be confident that the individual is a competent IT professional. Holding
CompTIA certification is an advantage to an individual because it provides
proof that they have the competence required to perform the job.
Certification can help individuals acquire employment in the IT industry,
in fact, many employers require CompTIA certification. If you're already
working in the IT field, the certifications you hold will determine your job
position and salary. Being CompTIA certified can give you the competitive edge
you need to compete in today's demanding job market.
CompTIA provides several different areas of certification. Network+ certification

have. It verifies that you have the knowledge to competently perform the
