Top 11 CCNA Word Bee #1

Top 11 CCNA Word Bee

Hi !!! everyone on today we are going to learn few CCNA words which is used in exam as well as lab which is given below with explanations for each and every words.

1. AAA (Authentication, Authorization, and Accounting). Authentication confirms the identity of the user or device. Authorization determines what the user or device is allowed to do. Accounting records information about access attempts, including inappropriate request.

2. Accounting In security, the recording of access attempts.

3. ADSL Asymmetric digital subscriber line. One of many DSL technologies, ADSL is designed to deliver more bandwidth downstream (from the central office to the customer site) than upstream.

4. AppleTalk DDP The AppleTalk Data Delivery Protocol (DDP) is the AppleTalk equivalent of the IP protocol. It defines a 24-bit address, with 16 bits defining the network and 8 bits defining the node.

5. ARP Address Resolution Protocol. An Internet protocol used to map an IP address to a MAC address.

6. Asynchronous The lack of an imposed time ordering on a bit stream. Practically, both sides agree to the same speed, but there is no check or adjustment of the rates if they are slightly different. However, because only 1 byte per transfer is sent, slight differences in clock speed are not an issue. A start bit is used to signal the beginning of a byte.

7. ATM Asynchronous Transfer Mode. The international standard for cell relay in which multiple service types (such as voice, video, or data) are conveyed in fixed-length (53- byte) cells. Fixed-length cells allow cell processing to occur in hardware, thereby reducing transit delays. ATM is designed to take advantage of high-speed transmission media, such as E3, SONET, and T3.

8. Authentication In security, the verification of the identity of a person or a process.

9. Authorization In security, the determination of a user or devices rights in a network.

10. Auxiliary port A physical connector on a router that is designed to be used to allow a remote terminal, or PC with a terminal emulator, to access a router using an analog modem.


11. 802.1Q The IEEE standardized protocol for VLAN trunking.

In our next session we will be publishing few more new CCNA Words !!! which is simplified to learn and memorize easily through these words for any CCNA readers.
