Top 11 CCNA Word Bee

Hi ! everyone on today we are going to learn our next 11 CCNA words with simplified explanations given below.

1. Star A method of connecting devices in which endpoints on a network are connected to a common central switch by point-to-point links.

2. SONET Synchronous Optical Network. A standard format for transporting a wide range of digital telecommunications services over optical fiber. SONET is characterized by standard line rates, optical interfaces, and signal formats. SONET is a high-speed (up to 2.5 Gbps) synchronous network specification developed by Bellcore and designed to run on optical fiber. STS-1 is the basic building block of SONET. It was approved as an international standard in 1988.

3. Storage router A device that sits between an IP network and storage devices, translating between disk IO protocols as they pass through non-IP and IP networks.

4. STP Shielded twisted pair. A two-pair wiring medium used in a variety of network implementations. Shielded twisted-pair cabling has a layer of shielded insulation to reduce electromagnetic interference (EMI). Can also refer to Spanning Tree Protocol, which is used to prevent bridging/switching loops.

5. Subnet broadcast address Same thing as broadcast address.

6. Subnet mask A 32-bit address mask used indicate the bits of an IP address that are being used for the subnet part of the address. Sometimes referred to simply as the mask.

7. Subnet Subnets are subdivisions of a Class A, B, or C network, as configured by a network administrator. Subnets allow a single Class A, B, or C network to be used instead of multiple networks, and still allow for a large number of groups of IP addresses, as is required for efficient IP routing.

8. Subnetting The process of subdividing a Class A, B, or C network and into smaller portions called subnets.

9. Switch A network device that filters, forwards, and floods frames based on the destination address of each frame. The switch operates at the data link layer of the Open System Interconnections (OSI) reference model.

10. Synchronous The imposition of time ordering on a bit stream. Practically, a device will try to use the same speed as another device on the other end of a serial link. However, by examining transitions between voltage states on the link, the device can notice slight variations in the speed on each end and can adjust its speed accordingly.

11. T1 A line from the telco that allows transmission of data at 1.544 Mbps.

Therefore, now we have learnt 11 CCNA words with easier way to understand and on our next session we will see few more like this 11 CCNA words bee coming shortly.
