Each year 1.5 million shelter animals are euthanized (670,000 dogs and 860,000 cats). Source: ASPCA. The solution is not to shelter unwanted pets, but to SHUT DOWN THE PET MILLS. Anyone who wants a pet will just have to adapt a great pet from a shelter.

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 specifies the skills and knowledge that a computer networking technician must have.
