Mark Jacob

Mark Jacob IT educator Mark Jacob helps students administer TCP/IP networks built with Cisco hardware—and do it well.

Mark Jacob is a Cisco specialist and a recipient of the 2012 Cisco Sirius Top Quality Instructor Award. Mark uses his current day-to-day experience as a network administrator to equip students with the real-world knowledge required to administer TCP/IP networks built with Cisco hardware—and do it well.

Mark teaches students straightforward methods to accomplishing Cisco network administrator responsibilities such as selecting routing protocols, setting up IP addresses, and performing subnetting. Students are amazed at how "easy" much-feared tasks such as subnetting can be once they learn Mark's methods, and the proof is in their success passing exams to obtain certifications.

Mark's passion for engineering led him to the IT profession after a career with the US Postal Service. Taking classes on his own time and starting out as an unpaid intern, Mark is now a network administrator with ten years of experience. This drive is clearly a bonus to students in his classes. A volunteer tutor of young students during his off-hours, Mark says, "I enjoy seeing the light go on in somebody as they learn."
