What distinguishes a VLAN from a LAN?

A local area network, or LAN, is a collection of computers or other gadgets that share a wired or wireless connection with a server located nearby. A VLAN is referred to be a subnetwork that can organize devices on different physical LANs.

Is VLAN equivalent to a subnet?

Only hosts that are a part of a VLAN will be able to access its broadcasts. A VLAN is a logical local area network. A subnet is a group of IP addresses that facilitates layer 3 host communication. We can build logical networks using the same physical network thanks to IP subnetting.

What are a hub and a bridge?

A network device called a hub enables multiple devices to connect with one another. A bridge is a piece of network hardware that links two different LANs using the same protocol. Hubs don't filter data at all. Data is filtered by bridges. Hubs employ a number of ports.

What do a switch and a hub do?

A hub is a networking tool that makes it possible to link numerous PCs to a single network. Ethernet, Firewire, or USB connections are all possible for hubs. A switch is a device that regulates whether electricity flows via a circuit on or off.

Switches - Do they have IP addresses?

The presence of machines on the same IP segment indicates that they are part of the same network. The computers connected to the switch, however, won't be able to communicate with one another because it is unable to assign IP addresses. They will receive a Private IP Address automatically (APIPA).

What distinguishes a bridge from a gateway?

Both bridges and gateways are essential networking components. A bridge joins two networks together that use the same protocol, whereas a gateway connects two disparate networks together that use separate protocols. This is the primary distinction between the two networking devices.

Describe 12U rack.

The "U" in 12U stands for the EIA-standard measurement unit known as the rack unit for equipment of the rack mount variety. 1.75′′ is equivalent to 1U in height. A wall cabinet with a 12U rating has an internal useable space of 21′′ (121.75′′).

Au in a server rack: What is it?

The quantity of equipment space in a server rack is measured in terms of server rack units, or U. A U has a height of 1.75 inches (44.45mm). 8 units of vertical server rack space make up an 8u rack. Please take note that equipment can be larger than 1U.

How are U counted in the rack?

The distance between the middle of the rack's top hole in the prior U space and the top hole in the present U space is the total rack unit. Within a rack unit, the distances between holes are all the same.

How do rack servers and blade servers differ?

The primary distinction between a rack server and a blade server is that a rack server is deployed as a standalone server in a case, whereas blade servers must cooperate with one another in a server chassis.
