An academic skill that the blogger learned, was to review the graded tests and quizzes to see which concepts he missed out on so that in the future he would be well prepared for it. Reviewing and comparing the tests and quizzes would give him an idea on which topics he needs to study.
Other than the academic skill, the blogger also learned that a person should never give up and he keeps on learning throughout his entire life, and that all of the improvements that the blogger made did not come all at once.
WAN or wide area network is a form of network meant for long distance communication between sites. It is made up of interconnecting local area networks spanning from a town to global communication of branches in an organisation.
For local area networks to be connected together to make a WAN, a dedicated high speed cable connection must be installed between sites. Fiber optics, among others, is the widely used dedicated WAN backbone connection. Cable connections are faster and moderately secure.
A VSAT is a wireless network connection method, where networks are connected using satellite dishes in remote networks, in the line of sight to a satellite, for WAN communication. It is not as fast or as secure as the cable connection, but can be used in remote area, where ISP in not available.
