reading this helped me pass the A+ core windows 1 exam and security plus
Format: Paperback
Problem is that I am 63 years old having earned the certificate and the industry doesn't seem to welcome older workers . I used to help maintain a fleet of printers at two large companies. I have read about other more experienced tech workers in their 50s getting jobs now working in pharma working at sterilization technicians because IT seems to be puking jobs.
