Technology and the constant advances in technology are changing the way we live & work. Computer networking is an engineering discipline that aims to study and analyze the communication process among various computing devices or computer systems that are linked, or networked, together to exchange information & share resources. Computer networking depends on the theoretical application and practical implementation of disciplines such as computer engineering, computer sciences, information technology, and telecommunication. One of the most overlooked skills in computer networking is the ability to explain & exchange technical information with others. Whether verbally, through email, or informal writing, network professionals that communicate well enjoy a significant advantage in building their careers. You can study IT computer courses at your own pace, and learn everything you need to know to pass a networking certification exam. The IT diploma courses include training for Cisco certifications or Microsoft certification. Cisco is the largest maker of network equipment and its certifications frequently rank among the best in IT.
