You might have come across the word “Gigabit Ethernet” being the common networking methods broadly used in local area networks. If not, then after reading this piece of content about what is gigabit ethernet you will be all aware of this term as well as related stuff like what is Gigabit Ethernet port used for, how fast is Gigabit Ethernet, what is 10 Gigabit Ethernet and a lot more similar stuff. A good starting point is to first throw light on what does the term imply.
Precisely speaking, this medium of transmission was introduced in the early 1970’s by Intel, Xerox and Digital. Due to its data sharing ability, this technology became the constituent of larger LAN technology system worldwide by allowing information transmission over long distances at very high speeds by employing optical fibre cabling options.
This transmission technology based on Ethernet protocol and frame format is capable of transmitting Ethernet frames at the rate of 1 Gbps. This technology serves as the backbone of much enterprise based networks and is an extension of 802.3 Ethernet standards. It also offers full compatibility with 100 m Ethernet nodes while supporting 1000 Mbps bandwidth.
The Gigabit Ethernet offers manifold benefits over regular 10 to 100 Mbps Ethernet by offering 100 times greater transmission rates. This transmission technology results in superior performance by featuring enhanced bandwidth capacity thus reducing associated bottleneck problems. Moreover, it can provide double bandwidth virtually by enclosing full-duplex capacity. However, to complement faster speed, cumulative bandwidth can also be attained by deploying Gigabit switches and server adapters. The quality of service as highlighted by this technology allows better audio and video services along with reduced latency. Moreover, large amount of data can be easily transferred by means of Gigabit Ethernet thus making it cost-effective and highly compatible with installed Ethernet nodes.
What is Gigabit Ethernet port used for?
An Ethernet port is used for plugging the Ethernet cable into an opening on a computer network. These ports are used for connecting metropolitan area network (MAN), wide area network (WAN) or wired hardware in Ethernet LAN. The port is used for allowing the Ethernet connection by accepting RJ-45 connection cables only. Most desktop computers constitute a built-in Ethernet ports being connected to Ethernet card for allowing the device to be connected to a wired network. However, the technology revolution in form of Wi-Fi connection doesn’t require the use of either Ethernet ports or Ethernet cables.
How Fast Is Gigabit Ethernet in Practice?
Practically, the speed of Gigabit Ethernet varies with respect to discrete factors such as inability of devices to transfer data at full 1 Gbps, network protocol overhead and transient failures or collisions leading to re-transmissions. In general, the use of standard cables under normal conditions allows for effective data transfer rates of up to 900 Mbps. However, traditional hard drives greatly limit the Gigabit Ethernet performance due to their ability to handle data transfer rates ranging between 25-100 Mbps. Similarly, routers constituting Gigabit Ethernet ports are incapable of supporting outgoing and incoming data processing at full transfer rates. Moreover, more concurrent network traffic sources and client devices can also limit the router processing ability to support maximum speed transfers. Another factor that can limit the connection speed can be attributed to bandwidth splitting the connection speed immediately to halve for two simultaneous connections.
What is Gigabit Ethernet cable?
The communication standards and computer networking systems recognize Gigabit Ethernet as part of Ethernet family capable of transmitting data at maximum 1 Gigabit per second. The Gigabit Ethernet cables are used as data transmission medium capable of transmitting data over long distances while deploying fibre optics or twisted pair copper cabling options.
What is a 10 Gigabit Ethernet?
Among the various computer networking technologies, 10 Gigabit Ethernet also known as 10 GigE, 10GE or 10GbE is a famous telecommunication technology offering fast data transmission speeds up to 10 billion bits per second. This standard technology offers full-duplex protocol thus eliminating the need of Collision Detection (CSMA/CD) or carrier sense multiple access protocol and full interoperability with existing Ethernet protocol as compared to traditional Ethernet technology. Although, 10 GbE offers the same benefits as of its predecessor but they offer an additional advantage of providing cost effective solution to support low latency and high-speed requirements as per the need of demanding applications.
Furthermore, within existing networks this technology can be easily deployed and is often termed as disruptive technology as it offers more cost-effective approach to transfer data across networks while using multi-mode or single mode fiber systems. This Layer 1 and Layer 2 protocol technology adheres to existing protocol attributes such as Ethernet frame format, minimum and maximum frame size and Media Access Control (MAC) protocol for support.
