In todays professional market, it is all about "who you know." Due to the advancement in technology, professional networking can now be done through such sites as LinkedIn. The benefit to having a profile on LinkedIn is that it allows you to connect with other people that have the same professional work experience or interest as you. Using technology allows for you to network with a variety of people that are all over the world with just a click of a button. The days have past where it takes days to hear back from someone in regards to job positions because the only communication was from Phone or snail mail. Now we have social sites, video conferencing and email that allows for faster communication and it is convenient.
The best ways to network without using technology is attend various events that are specific to your interest or experience. Job fairs, company conventions, specialized groups are just a few ways to network. Another way to network is by attending meetings by your employer will allow for you to connect and interact with other colleagues and provide personal interaction.
Both networking strategies are great so it just depends on your preference. I prefer both because they each have great benefits.
