The difference between a router and a switch: The switch is a cable to access the Internet, but everyone is on the Internet to dial the number, each using their own broadband, everyone has no effect on the Internet. The router has one more virtual dialing function than the switch. The computers that access the Internet through the same router share a broadband account. Everyone needs to interact with each other on the Internet.
The difference between the router and the switch II: The switch works at the relay layer, and the switch is addressed based on the MAC address. The router works at the network layer. According to the IP address, the router can handle the TCP/IP protocol, but the switch cannot.
The difference between the router and the switch III: The switch can make multiple computers connected to it form a local area network. If there is a proxy server, it can also realize the simultaneous Internet access function and all LAN computers share its bandwidth rate, but the switch does not have automatic router identification. The function of sending and arriving at the address of the data packet. The router can automatically identify the address where the packet was sent and arrived. The router is equivalent to * on the road and is responsible for traffic grooming and routing.
The difference between the router and the switch IV: To give a few examples, the router is a small post office, an address (IP), is responsible for a place to send and receive (a personal computer, a server, so your home to the Internet to this thing), the switch is the province The Grand Postal Center is responsible for the contact of various small places by one address. Simply put, the router is dedicated to the network, the switch is only for distribution, routing routing is to give you the way to let you access the Internet, the switch is only responsible for opening the door, the switch has no route above you can not get on the network.
The difference between the router and the switch 5: The router provides the service of the firewall. The router only forwards packets of specific addresses, does not transmit packet transmissions that do not support routing protocols, and transfers unknown destination network packets, thereby preventing broadcast storms.
The above is the difference between switches and routers that Xiao Bian summed up for you. I hope you can understand the difference between switches and routers and their respective functions.
Collimating lenses are optical lenses that help to make parallel the light that enters your spectrometer setup. These lenses allow users to control the field of view, collection efficiency and spatial resolution of their setup, and to configure illumination and collection angles for sampling
collimator is a device that narrows a beam of particles or waves. To narrow can mean either to cause the directions of motion to become more aligned in a specific direction or to cause the spatial cross section of the beam to become smaller (beam limiting device).
The molding glass collimator lenses are mainly designed with aspherical surface and made by molding technology.
Changchun Ruiqi now offer molding glass collimator lens--M series.The advantages of aspherical surface include small size,high performance,stable quality control in mass production and low cost comparing to traditional ground lens.Therefore, molding glass collimator lenses are commonly used in variety of applications,like industrial laser marking and detecting distance meters,laser projection and laser optical system.
Property
Molded Glass, aspheric Surface as laser collimator
Application
- Industrial and automotive alignment laser for small dimension
- Laser collimated for hand-held positioning and sensing
- Small dimension/short focal length requirement for optical design
- Application in high temperature or adverse circumstance
