whats difference between router and modem

What are the differences between hub, switch, router, and modem ??? What types of networks are available (local area, wide area, and enterprise )?How should the above components be connected for each network type? ========================================================== ============== Hub ------- a hub is also called a hub. It works on the physical layer (bottom layer) and does not have a matching softwar

routers and broadband routers have significant performance differences in routing. This behavior occurs because of the hardware structure. ADSL router CPU chip may be low-end network processor, such as: ARM7, the main frequency of only mhz,sdram memory is very small. Now the mainstream broadband routers, CPU frequency is up to 100Mhz above, SDRAM memory 16M above. There is also a difference in the ability

A netizen does not know the cat and the router, the hub, the switch difference between them what is different? Computer knowledge Network for everyone to answer: A cat has at least two ports: one to the telephone line and one to the RJ-45 port (network cable) Routers are generally one port: RJ-45 but one to connect the network, a LAN A router and a cat are not

firewalls. The wireless router is used more in Soho environment, in this environment, an AP is enough. In this way, a wireless router that integrates broadband access routers and AP provides a single machine solution that is easier to manage and cheaper than two separate machines. Wireless routers generally include a network address translation (NAT) protocol to support the sharing of network connections

, most wireless routers because of the ability to dial broadband, so you can directly with the ADSL modem connection for broadband sharing: Finally from costCome up to analyze 802.11B wireless AP and Wireless router price difference is not much, the general wireless router will be more than 100 yuan, 802

solution, which is easier to manage and cheaper than the two separate machine solutions. A wireless router generally includes a network address translation (NAT) Protocol to support network connection sharing among Wireless LAN users. This is a useful feature in the SOHO environment. They may also have basic firewalls or information packet filters to prevent port scanning software and other attacks against broadband connections. Finally, most wireles
