TP 9- Wireless Router Configuration

A wireless router is a device that performs the functions of a router and also includes the functions of a wireless access point. It is used to provide access to the Internet or a private computer network. Depending on the manufacturer and model, it can function in a wired local area network, in a wireless-only LAN, or in a mixed wired and wireless network

2-Objective:
Configuration of wireless router device

TP 8-Wireless Access point Network

A wireless network uses radio waves to connect devices such as laptops to the Internet and to your business network and its applications. When you connect a laptop to a WiFi hotspot at a cafe, hotel, airport lounge, or other public place, you're connecting to that business's wireless network



2-Objective:
Configuration of Router and wireless Access point devices.

Frame Relay

Frame Relay est un protocole de réseau étendu qui agit au niveau des couches physique et liaison de données du modèle OSI. Ce protocole est utilisé par les fournisseurs d’accès pour transmettre des signaux-vocaux et numériques entre réseaux locaux par l’intermédiaire d’un réseau étendu.
Frame Relay est un protocole de réseau étendu très répandu car il est de faible coût par rapport aux lignes dédiées et d’une grande flexibilité.

A la fin des années 70, des sites distants étaient généralement reliés en utilisant le protocole X.25. Ce protocole permettait d’obtenir une connexion réseau très fiable sur des infrastructures câblées non fiables grâce à un contrôle de flux et d’erreurs.
Frame Relay, le remplaçant de X.25, demande moins de temps de traitement que X.25 car il ne fournit pas de corrections d’erreurs.

TP 7: Vlan Network using HUB’s

1-what is Vlan ?
        A virtual local area network (VLAN) is a group of hosts with a common set of requirements that communicate as if they were attached to the same broadcast domain regardless of their physical location.
A traditional LAN would require all users of the same requirements and same IP subnet (broadcast domain) be connected to the same equipment.
By utilizing VLANs, the same users can be spread out over various geographical locations and still remain in their same IP subnet (broadcast domain).

2-Objective:
Configuration of switch and hub’s devices to obtain a virtual local area network (VLAN)
