Teachers used overhead projectors, mimeograph machines and chalkboards to make sure all students had the correct info for the lesson. Store owners hand-wrote prices on their goods and kept track of records in a big book. And when people traveled, they relied on an impossible-to-refold huge paper map, or at least a best guess, to get where they were supposed to be going.
It's clear that tech has improved many areas of personal and professional lives, including having easy access to all sorts of knowledge. What the current world also shows is that there's a growing need for people familiar with how to better use, create and fix all of our modern machinery, from phones to workplace desktops.
The IT team members are becoming some of the more valuable people in any organization, no matter the product or service produced. The modern business demands that repairs be done quickly to avoid down time, and also wants fixes done effectively by people with proper skills, rather than the usually less-than-successful strategy of "someone who kind of knows a little about computers."
Though colleges will suggest that completing a full academic program, such as a four-year computer science degree, is the best path to acquire all the proper credentials for any type of computer-related employment, there are many modern programs and educational settings where a shorter but still comprehensive program will suffice.
Here are some knowledge paths to consider.
This career path can provide troubleshooting to a workplace's desktops and laptops, everything from repairs to software updates on individual machines to configuring security at a large level. Microsoft and Apple both provide certificates for people who learn how to demonstrate knowledge of how to diagnose and repair an ailing computer.
Connecting computers and peripherals like printers to a single point can make a workplace extremely efficient. These skills also come in handy when there are multiple or remote offices, or employees who want to be in the field but still be able to connect to central area. There are a variety of certifications available in these, including demonstrating proficiency working with certain hardware companies like Cisco.
The growth of the popularity of the data cloud has made dramatic changes to the IT world – no longer do business have to rely on a finite amount of hardware, set up several layers of redundant system as 'just in case 'backups, or cross their fingers that nothing permanently breaks and no disasters ever hit the server room. Now, there's potentially unlimited storage capacity elsewhere but someone has to figure out how best utilize these tools easily and securely for a public or private cloud.
Overall, people interested in pursuing Information Technology careers have a wide variety of options to explore depending on their interests and experience.
Though it is possible to try to learn some of these areas by studying manuals or poking around in the back of your desktop, most businesses recommend taking classes, which will provide consistent, comprehensive and modern information about today's systems and provide opportunities to earn certain certifications and competencies.
