What purpose does a hub serve?
The hub is a device for connecting multiple ethernet devices together and making them act as a single network segment.
What is collison domain?
A collision domain is a physical network segment where data packets can collide with one another when being sent on a shared medium.A group of Ethernet or Fast Ethernet devices in a CSMA/CD LAN that are connected by repeaters and compete for access on the network. Only one device in the collision domain may transmit at any one time, and the other devices in the domain listen to the network in order to avoid data collisions.A collision domain is sometimes referred to as an Ethernet segment.
What is the IEEE VLAN standard?
The IEEE VLAN standard, specifically IEEE 802.1Q, defines a method for tagging Ethernet frames to support Virtual Local Area Networks (VLANs). This standard allows network administrators to segment a physical network into multiple logical networks, enhancing security and traffic management. By adding a VLAN tag to frames, devices can identify and segregate traffic based on defined VLAN IDs, facilitating better organization and efficiency within network infrastructures.
How would a repeater be used in an Ethernet segment?
Repeaters are usually used in coaxial based ethernet networks. For this purpose they are used to extend the length of a network segment. For example, in a 10base2 ethernet network the maximum length of a segment is 180 meters. A repeater could join two segments together to increase the length of the network and the number of clients in the network. In today's modern networks you will see neither coaxial networks nor repeaters in a LAN. Repeaters are used for DSL transmissions, but not for LANS.
What doe a hub do?
In computing an ethernet (network) hub is a device which usually looks like a small box with ethernet jacks on it which allows you to connect different devices together and allow them to act as one network segment. These days hubs are less common being replaced by routers or network switches instead.
Which of the two following might cause excessive data collisions on a ethernet network?
Excessive broadcasts, and using hubs instead of switches or routers to segment the network.
What is the maximum distance of Ethernet 10 Base2?
The maximum distance for Ethernet 10Base2, also known as thin coaxial Ethernet, is 185 meters (or approximately 607 feet) per segment. This standard allows for a total network length of up to 2000 meters when using multiple segments connected by repeaters. It operates at a speed of 10 Mbps and uses a BNC connector for connections.
Suppose you send data to an address that begins with the format prefix FF0E?
All devices on your network segment.
When two stations broadcast at the same time on a single segment of an Ethernet network what will happen?
When two stations broadcast simultaneously on a single segment of an Ethernet network, a collision occurs. Both stations' data packets interfere with each other, resulting in corrupted signals. Ethernet networks use a collision detection mechanism (CSMA/CD) to detect this, prompting the stations to stop transmitting, wait for a random time, and then attempt to retransmit their data. This process helps to manage access to the shared network medium and minimize data loss.
What is a special 32 bit number that when combined with a devices ip address informs the rest of the network about the segment or network to which the device is attached?
A Subnet Mask.
Star networks can support a maximum of only 1024 addressable nodes on a logical network?
A lower speed network such as a 10BaseT network can handle 1024 devices per segment; that is not the limitation on the entire network.
What devices are you tranmitting to when using 11111111 11111111 1111111 11111111 as a IP address?
All devices on your network segment. NOTE: In dotted decimal notation, which is the most common way of expressing IP addresses to make them easy for humans to read, this would be 255.255.255.255 or what is commonly referred to as all ones.
