Online Computer Networking Classes

Programs of study in this field teach students about the terminology, design, operation, and maintenance of the distributed processing systems that support cell phones, ATMs, and the Internet. The basic topics include hardware and software, network operating systems, data transfer and reliability enhancement. The best online classes in computer networking also teach students about interfaces, protocol layers, routing, congestion control, and security.

Knowledge Gained

These types of courses offer students access to knowledge on a wide variety of technological subjects, such as:

Computer/Network Security

Most curriculums include classes on computer/network security that teach students how to identify vulnerabilities and security threats. Some of the topics covered in these classes are risk analysis, identity authentication, cryptography, certificates, firewalls, intrusion detection, secure programming, and network protection.

Network Architecture

Classes on network architecture teach students about the standards and protocols that comprise the Internet and other kinds of networks. Common topics include sockets, TCP/IP, switching and routing, input/output multiplexing, and measurement of network performance.

Network Control

Students focused on network control will gain access to knowledge about configuring, managing, and monitoring computer networks. Common course topics include probability, datalink error detection, network routing algorithms, addressing, congestion control, authentication, performance metrics, and reporting.

Protocol Mechanisms

Online computer networking courses in protocol mechanisms provide knowledge about basic and advanced design and implementation techniques including randomization, signaling, scalability, and virtualization. These courses also cover information about attacks and countermeasures, vulnerabilities, protocols, port scanning, and signature identification.


These types of courses focus on computer hardware teach students about the essential hardware components of a computer system, including processors, motherboards, monitors, printers, and other peripheral devices. Classes also cover cables and connectors, power supply, buses, disk drives, and data storage devices.

Skills Developed

Students can expect to develop skills in the following areas:

Software Testing

Software testing courses introduce students to working with various common software types including concurrent, distributed, component based, object oriented, and web software. These online classes often cover practical applications of software research, development, modification, and testing.


Courses in this field also teach students how to install, configure, and maintain computer systems. These classes prepare them to use diagnostic programs and test equipment to solve problems with connectivity, hardware, and software.

File and Server Maintenance

Most curriculums teach students how to optimize server performance as well, a skill that helps businesses cut costs and stay competitive. These classes cover scheduled maintenance, log files, database backup and restoration, and firewall configuration.

Firewall Administration

Students can expect these programs to promote skills in designing, configuring, managing, and maintaining the firewalls that protect networks. These online courses also address audits, optimization, vulnerabilities, confidentiality, and access control.


The ability to gather information about the time, location, and cause of networking problems is in demand. Online courses teach students to test cables and other physical connections, isolate problems, debug software, and match symptoms to solutions.
