need to do is draw the object using the Render method. It is implemented by a line class that takes advantage of 4 coordinates: The start and end of the X value, the start and end of the Y value. It also has a color. When Render is called, the object draws a line of color specified by the name from Sx,sy to Ex,ey.

Ethernet switches are still commonly used, so I studied the high availability of stack 10/100 Ethernet switches. I would like to share with you here, hoping to be useful to you. Catalyst3524-PWRXL Ethernet switches are part of the CiscoSystemsCatalyst3500XL series, which is a series of scalable stack 10/100 and Gigabit Ethernet switches that provide optimal performance, manageability and flexibility, as well as unparalleled investment protection.

Several Optical Fiber interfaces (ST, SC, LC, FC)I have never been very clear about Several Interfaces of optical fibers. I have seen real images on the Internet and shared them with you. The optical fiber is sometimes annoying and summarizes several commonly used optical fiber connectors.The above figure shows LC to LC. LC is the SFP commonly used by routers and the line head inserted by mini GBIC.FC to SC, FC End Plug fiber step frame, SC end is catalyst or other or above
Cisco has become a leader in the communication industry, and its product performance is still very good. Here we mainly explain the common problems and solutions of Cisco switches. Here we will share with you some of them, I hope it will be useful to you.
