Glossary

Technology evolves at a rapid-fire pace. That’s why we’ve built an easy-to-use glossary to help you better understand the terms, technologies and trends that impact your business.

DSL bypasses the circuit-switched lines that make up that network and yields much faster data transmission rates than analog modem technologies.
