- 18. Modem
- 19. Repeater Repeater receives signal from a transmitter, amplifies it, and retransmits it to a receiver
- 21. Hub Hub is the central connection point in a network that uses star topology
- 22. Switch Like hub, switch works as the central connection point in a network. However when a switch receives a packet from a sending computer, it examines the destination address (i.e. MAC address of the destination computer) from the packet header and retransmits the packet to the destination computer only.
- 23. Access point Access point in wireless LAN (Wi-Fi) functions like a hub or a switch in wired network. It connects computers or devices together to create a wireless network
- 24. Router Router functions to forward packets across different networks. Router maintains a routing table. The routing table contains IP addresses of other networks routers.
- 25. Residential Gateway Residential gateway is basically a router that is configured to enable the sharing of a single Internet connection (subscription) by multiple users in a home network.
- 26. Gateway Gateway functions to connect two completely different networks. It performs protocol translation.

- 33. Calculation
- 34. Network Operating system Functions • File and print sharing. • Account administration for users. • Security.
- 35. Example for NOS • JUNOS, used in routers and switches from Juniper Networks. • Cisco IOS • Linux • Microsoft Windows Server • Novell Netware
- 36. DHCP Dynamic Host Configuration Protocol (DHCP) is a network protocol that enables a server to automatically assign an IP address to a computer from a defined range of numbers
- 37.
