Types of Interface in Cisco Router: What is Fast Ethernet Interface, Gigabit Ethernet Interface, and Serial Interface in Cisco Router
The interface is the point of contact between two routers or router and a switch etc. Cisco routers have various kinds of interfaces mounted on them. Ghetto whisky riddim rar download. Some of the important physical interfaces that can be seen on the router are as follows
This knowledge is irrelevant to most home users. Still, if you frequently move big files between computers or stream extremely high-bandwidth video, a better Ethernet cable can make a huge difference. Serial interfaces use time domain multiplexing (TDM) and use clock speeds to synchronize. They also must have one side set as DCE and DTE. Serial interfaces can sometimes use t1 cabling which looks very similar to Ethernet, but it's wired different or it can use big ass serial connectors. One part of the explanation of the different behavior between Ethernet/FastEthernet and serial interfaces is that the serial interfaces use a keepalive mechanism that sends keepalive packets over the serial interface and must receive keepalive packets over the serial interface.

b. Fast Ethernet interface
c. Serial interface
d. FDDI interface
e. Token Ring interface
f. Gigabit Ethernet interface
Each interface has its own specifications. Let us discuss each of them in detail
Ethernet interface:
Ethernet is most commonly seen in Local Area Networks and Metropolitan Area Networks. Ethernet operates at a speed of 10 Mbps (Mega bits per second) and uses a media standard 10 Base T. Ethernet was standardized in 1983 as IEEE 802.3. Ethernet divides the stream of data into frames having source and destination addresses along with error checking capabilities.
Fast Ethernet interface:
Fast Ethernet, is based on Ethernet and operates at speeds as high as 100 Mbps with the media standard 100Base T. Gb instruments gmt 312 manual. Fast Ethernet was standardized in the year 1995 as IEEE802.3u.
Gigabit Ethernet interface:
Gigabit Ethernet describes various technologies that help to transmit data at a speed of 1000 Mbps. Gigabit Ethernet came into existence in 1999 with the standards IEEE 802.3 -2008. Designpro 5.0 free download. The Gigabit Ethernet uses the media standard 1000Base T.
Serial interface:
The serial interface is used in long distance communication such as Wide Area Networks. Serial interfaces can be either configured as Data Communication End or Data Terminal End. If two serial ports have to communicate with each other, they must be synchronized with the appropriate clock frequency and allocate proper bandwidth.
FDDI Interface:
FDDI stands for Fibre Distributed Data Interface. FDDI is a standard data transmission technique in Local Area Networks. FDDI standard uses optical fibre as a medium for data transmission. Later the standard was even developed to transmit data through copper cables. FDDI can transfer data at a speed of 100 Mbps. The cable allows the data transmission up to the distance of 200kms. FDDI passes tokens to the systems connected to the network to avoid data collision.
Token Ring Interface:
Token ring was first developed by IBM in 1984 and later standardized as IEEE 802.5. The interface generates 3-byte frame called token. The token travels along the network in a logical ring format. The client uses the token to transmit the data by holding the token with it and releases the token once the transmission is done. This method reduces data collision

Main Difference
Ethernet is a Local Area Network, which is used to connect different people working at a place. It is opposite of the internet which is for the use of individuals who want to surf on their own. Ethernet helps people work in a group to get the job done at a quick rate. It is the most common used technology in its field and contributes to keeping multiple computers connected to each other or to one central computer and is mostly used in different organizations where several people are performing a task. Many types of Ethernet are there for use, but there are two main types of Ethernet which are currently more frequently used, they are Fast Ethernet and Gigabit Ethernet. Both have some similarities and differences between them, the latter ones will be discussed in this paragraph. The simplest of difference between them is their speed. An Ethernet, which is working at the speed of 100 Mbps, is known as Fast Ethernet while the one which is operating at 1000 Mbps is known as Gigabit Ethernet. This is the basis of why they are named differently even when they both use the same bandwidths and modes such as half and duplex. A gigabit Ethernet works 10 times faster than a fast Ethernet. It can also be assumed that a quick card can run on speed such as 10 Mbps and 100 Mbps while a gigabit card can run at speeds such as 10, 100 and 1000 Mbps respectively. Because of these features, gigabit is costlier than the fast one. If someone wants to upgrade from quick to gigabit Ethernet, it won’t cost them much, and the process will be simple. If the up gradation is from gigabit to fast one, it can cost a lot more, and the process will be complicated. That said, there are more connectivity and networking problems in the gigabit version because most of the technologies are still to upgrade them to the standard of working at such high speeds. Most of the fast internet works at a frequency of 125 MHZ while the rate of Gigabit is slightly higher.
Comparison Chart
Fast Ethernet | Gigabit Ethernet | |
Definition | Ethernet which runs at the maximum speed of 100 Mbps | The one who works at the speed of 1000 Mbps |
Delays | More | Less |
Range | Has a range of 10 km | Has the limit of 70km |
Configuration | Less complicated in configuration | More configuration errors in gigabit Ethernet |
Relation | Cannot work as Gigabit | Can work as fast |
Definition of Fast Ethernet
Most of the properties of a quick card are the same as the previous 10 Mbps version, but the main difference is the delay which has decreased considerably from 51.3 milliseconds to 5.12 milliseconds. This has led to an increase of speed which is 10 times more than the previous version. An Ethernet, which has a speed of 100 Mbps, is known as fast Ethernet. It makes use of 10BaseT which results in faster speeds and fewer delays. It came into the market in 1995 and has different features such as it has several PHY layers. There are original Ethernet MAC operators still in this version, but they are higher in speed. The length of wire network can be up to 10 km. There was less delay as comparison to the previous versions which gave it the advantage over others.
Definition of Gigabit Ethernet
Simplest of the definition of this type of Ethernet is that is works at the speed of 1000 Mbps, therefore, got the name gigabit. It uses a frame format of 803.2 and also has half duplex and full duplex modes of working. The maximum length of this system can be up to 70 km therefore most universities and bigger branches use this. It has different versions of itself such as 1, 10, 40 and 100 gigabits where the system works on this speed per second. It also has a different CSMA/CD and farming format while the physical outworking is also variable. The slot time is higher too and can reach 512.
Differences in a Nutshell
- An Ethernet which runs at the maximum speed of 100 Mbps is known as Fast Ethernet while the one who works at the speed of 1000 Mbps is known as Gigabit Ethernet.
- There is more delay in the fast Ethernet while the delay in Gigabit version is less.
- Fast Ethernet has a range of 10 km while a Gigabit Ethernet has the limit of 70km.
- Fast Ethernet is less complicated in configuration while there are more configuration errors in gigabit Ethernet.
- A gigabit Ethernet can work on fast Ethernet, but vice versa is not possible.
