In this course, we trace the evolution of networks and identify the key concepts and functions that form the basis for layered architecture. We introduce examples of protocols and services that are familiar to the students, and we explain how these services are supported by networks. Further, we explain fundamental concepts in digital communication, and focus on error control techniques that include parity check, polynomial code, and Internet checksum. Students will be required to have some previous programming experience in C-programming (C++/Java), some fundamental knowledge of computer organization and IT architecture and a background in computer science is a plus.

由 AS 提供Jun 28, 2020
It is a good course to cover the basics computer networking. It is simple and the workload is less. Try to go through other sources simultaneously to get in-depth knowledge on the topic.
由 DM 提供Jun 6, 2020
Really fantastic experience learning with Coursera. Awesome study materials and choice of syllabus. Just the perfect one for new faces in this field. Keep it up Team Coursera!!!
由 TX 提供Apr 27, 2020
Good introductory course to network communications. Far from a semester's worth of content, however, which is supposed to be what distinguishes Coursera from other platforms.
由 PR 提供Jun 3, 2020
Fundamentals of Communication in Networking has been explained in a detailed manner ... Thank you and all the best for who are interested to seek knowledge from coursera.
关于 Computer Communications 专项课程
This specialization is developed for seniors and fresh graduate students to understand fundamental network architecture concepts and their impacts on cyber security, to develop skills and techniques required for network protocol design, and prepare for a future of constant change through exposure to network design alternatives. Students will require a prior knowledge of C programming, an understanding of math probability and a computer science background is a plus.
常见问题
我什么时候能够访问课程视频和作业？
Access to lectures and assignments depends on your type of enrollment. If you take a course in audit mode, you will be able to see most course materials for free. To access graded assignments and to earn a Certificate, you will need to purchase the Certificate experience, during or after your audit. If you don't see the audit option:
- The course may not offer an audit option. You can try a Free Trial instead, or apply for Financial Aid.
- The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
