Types The USB 1.0 specification supported speeds up to 12 megabits per second (Mbps.) USB 2.0 supports speeds up to 480 Mbps. Ethernet supports three different speeds.

The slowest operates at 10 Mbps. Fast Ethernet operates at 100 Mbps. The fastest type is Gigabit Ethernet, which transmits signals at 1000 Mbps. Features USB is compatible with plug and play devices. This means that when you plug in a USB device, the device's drivers will begin to install automatically. When you attach a device to your computer by Ethernet, you may have to install the drivers manually.

Aug 25, 2017. Q1: What are the differences between serial interface and ethernet interfaces. Fast Ethernet is one of the option for any speed above T1/E1, other TDM options which can be offered are DS-3 and STM1 which can be offered on sub-rated basis as well. L2 VPN woks on VLAN tags and L3 VPN termiantes on a L3 device.

If a CD came with your device, place it in the drive to install the software and configure the device. Some modems that connect by Ethernet require no drivers. However, your Internet Service Provider (ISP) will probably provide you with software to configure your system to connect to the Internet.

Identification A USB cable has metal connectors on both ends. The type 'A' connector is flat and broad. This end connects to your computer.

Many computers have USB ports both on the front and on back. These can be identified by a trident symbol, which shows a medium-sized circle connected to three lines. One line ends in a square, one in a smaller circle and one in a triangle. The 'B' connector connects to your device. This plug is keyed so that you can't insert it in your device the wrong way. Ethernet looks like a large telephone cable.

It has a plastic tab on the end that will catch inside the plug when you insert it in back of your computer. Benefits Ethernet is the best choice for connecting a broadband modem to your computer.

This is because most broadband connections will function at speeds that are less than 30 Mbps. Fast Ethernet is more than adequate to handle these speeds. Ethernet is usually the best way to connect a local area network since it doesn't have to share resources with other devices. Considerations Even if your router and access points have USB connections, Ethernet may still be a better option. USB bandwidth is shared between all the devices connected to your computer by USB ports.

This is fine if you're connecting a printer, a digital camera and a scanner, since you probably won't be using them all simultaneously. If you use USB for your networking needs, you may find that your router or modem are competing with other peripherals for resources. Also, Ethernet connections are dedicated to network traffic. Ethernet cables of up to 328 feet can function optimally, while USB cables are typically limited to 6 feet.

With a point-to-point link, there is exactly one device on the other end of the link.

There is one, and only one, neighbor per interface. Download Opera Mini 8 Handler Jar. If you route a packet out that interface, it can only go one place, so the concept of a shared subnet doesn't really apply. With a shared medium however, there can be many neighbors on an interface, so you need a way specify which one you are sending to. On Ethernet, you use the MAC address to specify the neighbor. With the IP protocol, the IP addresses need to be in the same subnet for the neighbor resolution (ARP or Neighbor Discovery) to work correctly. IPv6 routing protocols can use the link-local address to form relationships. They are on the same subnet, just not necessarily a globally-routable subnet.

• • • • • • •. It works because PPP automatically installs a /32 of the other side of the link into the routing table as a connected route. May I ask few questions? My net instructor told me that using serial interface is always point to point. When I used PPP, I was able to ping 192.168.0.1/24 from 1.1.1.1/8. But when I used HDLC, I was not able to ping 192.168.0.1/24 from 1.1.1.1/8.

Is it because PPP uses IPCP to map and install a host route using prefix 32, and HDLC doesn't do that? I heard that serial interfaces are not used for today. Back then, serial interfaces were definitely needed because FastEthernet over copper is limited to a max distance of 100 meters. Is this info correct? • • • • • • •. Serial interfaces themselves are point-to-point, but can connect into something like a multipoint frame relay network. If you mean you set one side of the link to 192.168.0.1 and the other to 1.1.1. Yugioh The Duelist Of The Roses Isotope. 1 and tried to ping across, then yes the host routes created by default in PPP would be the answer.

Serial interfaces are rarely used today; typically we either use long haul Ethernet directly, or more often hand off via Ethernet to some other CPE device that takes care of handling the long haul portion. • • • • • • •. Really cool fact about the serial protocol PPP, during the IPCP phase the two nodes negotiate their ip addresses. So router1 essential tells router2 'this is my ip address(1.2.3.4/31)' router2 could have 5.6.7.8/31 configured on his incoming interface from router1 and he would advertise 'this is my ip address(5.6.7.8/31), and it wouldnt matter. Router1 would install a route to 5.6.7.8 going out interfaceX, And router2 would do the same for the route to 1.2.3.4.

The other thing I found interesting is you can use /31 address space, so there are no wasted addresses.
