Information Technology or IT has become an extensive career choice. Knowing what IT is and the discipline entailed with it is crucial if you want to take up an IT course.
What is Information Technology?
Information Technology or IT is the use of an organization’s computer systems to manage its information. These include physical hardware as well as software. IT does not involve personal computing. You will work to support the infrastructure of a business when you work in the IT field. IT covers more than computers. These include hardware, such as servers and printers, and software, like databases and proprietary applications.
Managing a company’s information is not simple and easy because you need to keep the employees’ computers working well at all times. You also have to ensure the protection of its data backup archives.
What are the disciplines circumscribed by IT?
IT is a broad field. There are dozens of various specializations you could find.
Help Desk Technician
A help desk technician helps clients with all sorts of troubleshooting. From something simple like being unable to figure out how to use Excel to something familiar like the internet service is down or unstable. You do not have to worry about the bigger picture, such as pruning databases, because your primary concern is user-level problems. You must have excellent communication skills and patience, a lot of it. Familiarity with the operating systems and programs your clients use is also a must.
A Network Administrator sets up networks for new business and maintains existing ones. You will set up a new VPN for a second campus or remote workers, test the weak points of the network, and install an on-site email system. You have to get everything done at once because networks are sensitive to changes.
Security is a vast field, and it keeps on growing. Computers no longer offer mere convenience like before and are now a necessary part of modern businesses. There are many people with malicious intent who come up with ways to attack and steal a company’s information. Whether they succeed or fail, it will often mean a disaster for the company.
Working on IT security depends on your level of expertise. Some put in place proper security software while others educate end-users to scan for threats in a productive manner. There is always more work involved with a larger company, and keeping these companies secure can be a challenge.
IT is not the same as Computer Science. In IT, you do not have to understand the theory behind applications. Your concern is about existing systems and mastering them to help your clients become more efficient. Several IT courses in Singapore will help you achieve those. Taking up an IT course will provide you with essential skills and characteristics.
