CompTIA A+ Certification is designed to be a "vendor-neutral" exam that measures your knowledge of industry-standard technology.
It's just plain old Catch-22. You need the work to get the experience but you can't get that first job to give you a track record and therefore verifiable experience. With this logic, it amazes me that anyone actually gets into IT!
Qualifications help but even that is no guarantee nowadays of getting an IT Job. And what do you do when you don't have qualifications but you want to start now? I mean right now, not 3 months later after you've paid a fortune for certification and given up your job to have enough study time.
All is not lost. You have two alternatives.
What is Computer Networking?
A network is a collection of connected intelligent computing devices. The connection is not necessarily a fancy one. A connection between two computers by direct cabling is qualified to be a network. By this definition, a workstation which is loaded with a computer, a scanner, and a printer, is not treated as a network.
A network can consist of two computers connected together on a desk or it can consist of many Local Area Networks (LANs) connected together to form a Wide Area Network (WAN) across a continent. The key is that two or more computers are connected together by a medium and are sharing resources. These resources can be files, printers, hard?drives, or CPU number-crunching power.
A Local Area Network (LAN) is a smaller network within one location or between several buildings A Metropolitan Network (MAN, politically incorrect, no WOMAN!) is a midsize network spanning the city. A Wide Area Network (WAN) is a giant network spanning across several cities or even several continents.
