O que é a regra 5-4-3 e em qual arquitetura ela é usada?



The 5-4-3 rule is a guideline used in the design of shared Ethernet networks which promotes optimal traffic flow. This refers to the number of repeaters and segments that must be present on shared Ethernet backbones set up in a tree topology.

What does the 5 to 3 rule mean? Three-fifths compromise, compromise agreement between delegates from the Northern and the Southern states at the United States Constitutional Convention (1787) that três quintos da população escrava seriam contados para determinar a tributação direta e a representação na Câmara dos Deputados.

also,  What is the maximum size of a 10Base5 network using 3 repeaters? The maximum length of any particular segment of a 10Base5 network is metros 500, hence the 5 in 10Base5. If distances longer than this are required, two or more segments must be connected using repeaters.


What is the four repeater rule? The rule mandates that there can only be a maximum of five segments, connected through four repeaters, or concentrators, and only three of the five segments may be mixing segments. This last requirement applies only to 10BASE5, 10BASE2, and 10BASE-FP Ethernet segments.

What does 5 mean in 10Base5?

The name 10BASE5 is derived from several characteristics of the physical medium. The 10 refers to its transmission speed of 10 Mbit/s. The BASE is short for baseband signaling (as opposed to broadband), and the 5 stands for the maximum segment length of 500 meters (1,600 ft).

similary What is the difference between 10Base2 and 10Base5?

10Base-2 works for 10 Mbps networks only and uses coaxial cable. Maximum length is 185 meters and BNC “T” connectors are used to connect to the computers; there are special terminators at each of the coaxial cable. 10Base-5 works for 10 Mbps networks only and uses thick coaxial cable.

What is the maximum size of a 10Base2 network using 5 repeaters? A 10Base2 network could therefore span up to 925 meters and a 10Base5 network up to 2,500 meters which states that there can only be 5 segments in a series and 4 repeaters between these 5 segments, although only 3 of the segments can be populated with devices.

What is the maximum size of a 10Base2 network using 4 repeaters? A 10Base2 network could therefore span up to metros 925 and a 10Base5 network up to 2,500 meters which states that there can only be 5 segments in a series and 4 repeaters between these 5 segments, although only 3 of the segments can be populated with devices.

What is a collision domains in networking?

A collision domain is a network segment connected by a shared medium or through repeaters where simultaneous data transmissions collide with one another. The collision domain applies particularly in wireless networks, but also affected early versions of Ethernet.

What are the three main functions in the operation of the Ethernet switch? Three basic functins of a switch are Learning, Forwarding and Preventing Layer 2 Loops.

What is thicknet and thinnet?

Thicknet was the original Ethernet wiring, but Thinnet, which is cheaper and can be installed more easily, is the more commonly installed Ethernet wire. Thicknet continues to be used for backbone wiring. An alternative to Thinnet on an Ethernet network is twisted pair.

What is 10BASE F? 10BASE-F, or sometimes 10BASE-FX, is a generic term for the family of 10 Mbit/s Ethernet standards using fiber optic cable. In 10BASE-F, the 10 represents a maximum throughput of 10 Mbit/s, BASE indicates its use of baseband transmission, and F indicates that it relies on medium of fiber-optic cable.

What does 2 stand for in 10BASE2?

The name 10BASE2 is derived from several characteristics of the physical medium. The 10 comes from the transmission speed of 10 Mbit/s. The BASE stands for baseband signalling, and the 2 for a maximum segment length approaching 200 m (the actual maximum length is 185 m).

What is the speed of 100BASE-TX cable?

100BASE-TX is the technical name of Fast Ethernet over twisted pair cables. It is a predominant form of Fast Ethernet carrying data traffic at 100 Mbps (Mega bits per second) in local area networks (LAN). It was launched as the IEEE 802.3u standard in 1995.

What is the difference between 10Base-T and 100BASE-TX? Both of these terms refer to a networking standard called “Ethernet” which is the most common way of connecting computers together The terms 10Base-T (Ethernet) and 100Base-T (Fast Ethernet) refer to the performance capability of the Network Interface Card (NIC) 10Base-T has a rated transfer speed of 10 Megabits per …

What is 10Base F? 10BASE-F, or sometimes 10BASE-FX, is a generic term for the family of 10 Mbit/s Ethernet standards using fiber optic cable. In 10BASE-F, the 10 represents a maximum throughput of 10 Mbit/s, BASE indicates its use of baseband transmission, and F indicates that it relies on medium of fiber-optic cable.

What is ThinNet and Thicknet?

Ethernet based LANs using thick cable for inter-connection is referred as Thicknet. While ethernet systems using thinner coaxial cable is referred as Thinnet. Thicknet is also referred as 10Base5 systems, where 10 means 10Mbps speed. Base means baseband and 5 denotes 500 meter max.

How does 10Base2 work? 10Base2 is among the family of Ethernet network standards for local area networks (LAN) that uses a thinner version of coaxial cable to establish a network path or medium and operates at a speed of 10 Mbps to carry out baseband transmission. 10Base2 is also known as cheapernet, thinwire, thinnet and thin Ethernet.

What type of cable is used in a 10Base2 network?

10BASE2 uses RG-58A/U cable or similar for a maximum segment length of 185 m as opposed to the thicker RG-8-like cable used in 10BASE5 networks with a maximum length of 500 m.

What is the difference between 10Base2 and 10BASE5? 10Base-2 works for 10 Mbps networks only and uses coaxial cable. Maximum length is 185 meters and BNC “T” connectors are used to connect to the computers; there are special terminators at each of the coaxial cable. 10Base-5 works for 10 Mbps networks only and uses thick coaxial cable.

What is the difference between hub and switch?

PRINCIPAIS DIFERENÇAS

A Hub is a networking device that allows you to connect multiple PCs to a single network, whereas a Switch connects various devices together on a single computer network. A Hub operates on the physical layer, whereas Switch operates on the data link layer.

What is difference between collision domain and broadcast domain? The Collision domain refers to a set of devices in which packet collision could occur. Broadcast domain refers to a logical set of reachable computer systems without using a router.

What is switch in networking?

A network switch is a device that operates at the Data Link layer of the OSI model—Layer 2. It takes in packets being sent by devices that are connected to its physical ports and sends them out again, but only through the ports that lead to the devices the packets are intended to reach.

What are the 4 types of switches in networking? Tipos de Switches de Rede

  • Switch KVM.
  • Interruptor Gerenciado.
  • Comutador não gerenciado.
  • Interruptor inteligente.
  • Interruptor PoE.

Por que o STP é usado?

O Spanning Tree Protocol (STP) é um protocolo da Camada 2 executado em pontes e switches. … O principal objetivo do STP é para garantir que você não crie loops quando houver caminhos redundantes em sua rede. Os loops são mortais para uma rede.

What is difference between router and switch? Just as a switch connects multiple devices to create a network, a router connects multiple switches, and their respective networks, to form an even larger network. … In addition to connecting multiple networks together, the router also allows networked devices and multiple users to access the Internet.
