Communications Fundamentals

LIDO TELECOMMUNICATIONS ESSENTIALS®

One of the biggest challenges facing professionals in the information technologies and telecommunications (IT&T) sector is conquering the dense, seemingly endless, yet absolutely essential language of telecommunications. During Part 1, telecommunications fundamentals are presented in layman's terms, laying the foundation for understanding the basic principles of telecommunications transmission and networking. The focus is on developing an understanding of the forces driving the revolutionary change in infrastructures worldwide, on providing clear explanations of communications fundamentals, the differences between circuit and packet switching, the nature of transmission media, and the architecture of the public switched telephone network (PSTN) infrastructure. Part 1 will result in an appreciation and understanding of the fundamental principles of telecommunications and the supporting infrastructures.
