Top 11 CCNA Word Bee

Hi !!! everyone on today we are going to learn our next 11 CCNA words for preparation of exams or it will be very helpful to our basic knowledge in networking which is given below with explanation.  

 

1. Partial mesh A network in which devices are organized in a mesh topology, with some network nodes organized in a full mesh but others that are connected only to one or two other nodes in the network. A partial mesh does not provide the level of redundancy of a full mesh topology but is less expensive to implement. Partial-mesh topological generally are used in the peripheral networks that connect to a fully meshed backbone.

2. PCM Pulse code modulation. A technique of encoding analog voice into a 64-kbps data stream by sampling with 8-bit resolution at a rate of 8000 times per second.

3. PDU Protocol data unit. An OSI term to refer generically to a grouping of information by a particular layer of the OSI mode. More specifically, an LxPDU would imply the data and headers as defined by Layer x.

4. Ping Packet Internet groper. An Internet Control Message Protocol (ICMP) echo message and its reply; ping often is used in IP networks to test the reach ability of a network device.

5. Port number A field in a TCP or UDP header that identifies the application that either sent (source port) or should receive (destination port) the data inside the data segment.

6. PPP Point-to-Point Protocol. A protocol that provides router-to-router and host-to network connections over synchronous and asynchronous circuits.

7. Prefix notation A shorter way to write a subnet mask in which the number of binary 1 s in the mask is simply written in decimal. For instance, /24 denotes the subnet mask with 24 binary 1 bits in the subnet mask. The number of bits of value binary 1 in the mask is considered to be the prefix.

8. PRI Primary Rate Interface. An Integrated Services Digital Network (ISDN) interface to primary rate access. Primary rate access consists of a single 64-kbps D channel plus 23 (T1) or 30 (E1) B channels for voice or data.

9. Protocol Type field A field in a LAN header that identifies the type of header that follows the LAN header. Includes the DIX Ethernet Type field, the IEEE 802.2 DSAP field, and the SNAP protocol Type field.

10. PSTN Public Switched Telephone Network. A general term referring to the variety of telephone networks and services in place worldwide. Sometimes called POTS.

11. PTT Post, telephone, and telegraph. A government agency that provides telephone services. PTTs exist in most areas outside of North America and provide both local and long-distance telephone services.

Therefore, through this CCNA words bee we can learn easily with this simplified explanations to understand and by the way on our next session we will see you on our another 11 CCNA set of words.
