Hi, I'm Bo with Free Code Camp. This network engineering course was developed by Brian Farrell, and instructor with Edmonds college. It will prepare you to configure, manage and troubleshoot computer networks. Also, the course is a great way to prepare for a comp Tia's network plus exam. So let's start. Hello, I'm Brian ferrill. And welcome to pace... Read More

Key Insights

• 🌐 GSM and CDMA are two main cellular network technologies, with GSM being the global standard and CDMA used by certain carriers.
• 😒 Metro Ethernet provides Ethernet connections through the use of RJ-45 connectors and is commonly used in municipal networks.
• 😄 Leased lines offer dedicated circuits for reliable communication, with options like DSL and fiber optic connections.
• 😒 Satellite WAN connections use microwave transmissions to reach remote locations, but latency can be a challenge.
• 🖼️ Frame relay and ATM are packet-switched networks, with frame relay providing virtual circuits and ATM utilizing fixed-length cells.

Questions & Answers

Q: What is the main difference between GSM and CDMA network connections?

The main difference lies in the technology used by the cellular carriers. GSM is used by AT&T and T-Mobile, while CDMA is used by Sprint and Verizon. They are not compatible with each other.

Q: Can you explain the concept of leased line connections?

Leased lines are dedicated circuits between two endpoints, often offered as digital Point-to-Point connections. They can use DSL or fiber optic technology, providing reliable and secure communication.

Q: What are the advantages and disadvantages of satellite WAN connections?

Satellite WAN connections allow for network extension to remote areas, but they can suffer from latency issues due to the distance signals need to travel. Additionally, they require line-of-sight relay stations for transmission.

Q: How does Frame Relay differ from Asynchronous Transfer Mode (ATM)?

Frame Relay is a variable length packet-switched network that utilizes virtual circuits for data transmission, while ATM uses fixed-length cells but has inefficient bandwidth utilization.
