Introduction aux réseaux Training
installer et administrer des réseaux locaux - certification AVIT® à distance en option
- Program
- Participants / Prerequisite
- Intra/Tailored
This course, including both theoretical and hands-on exercises, will help you to understand and practice enterprise networking. Most important aspects, including software and hardware parts will be explained. Interconnection devices such as switches and routers, networking protocols such as TCP/IP, and high-level application protocols such DNS, DHCP, HTTP and others will be examined thoroughly. Following this course, you will be able to set up local area networks and to connect and manage PCs running Windows or Linux.
