Have you heared about CCNA?


What is CCNA?

CCNA (Cisco Certified Network Associate) is a popular certification for computer network engineers provided by the company named Cisco Systems. It is valid for all types of engineers including entry-level network engineers, network administrators, network support engineers and network specialists. It helps to become familiar with broad range of networking concepts like OSI models, IP addressing, Network security, etc.


It is estimated that more than 1 million CCNA certificates have been awarded since it was first launched in 1998.

The CCNA certificate covers a broad range of networking concepts. It helps candidates to prepare for the latest network technologies they are likely to work on.

Have you heared about CCNA?


Some of the common topics covered under CCNA certification include:

  • OSI models

  • IP addressing

  • WLAN and VLAN

  • Network security and management (ACL included)

  • Routers / routing protocols ( EIGRP, OSPF, and RIP)

  • IP Routing

  • Network Device Security

  • Troubleshooting


Note: Cisco certification is valid only for 3 years. Once the certification expires the certificate holder has to take CCNA certification exam again.



Why to acquire a CCNA certification?

  • The certificate validates a professional's ability to understand, operate, configure and troubleshoot medium-level switched and routed networks. It also includes the verification and implementation of connections via remote sites using WAN.

  • It teaches the candidate how to create point-to-point network

  • It teaches about how to meet users requirement by determining the network topology

  • It imparts on how to route protocols in order to connect networks

  • It explains about how to construct network addresses

  • It explains on how to establish a connection with remote networks.

  • The certificate holder can install, configure and operate LAN and WAN services for small networks

  • CCNA certificate is a pre-requisite for many other Cisco certification like CCNA Security, CCNA Wireless, CCNA Voice, etc.

  • Easy to follow study material available.

What is STP? - Explain Advantages and Disadvantages

The Spanning Tree Protocol is a network protocol that builds a loop-free logical topology for Ethernet networks. The basic function of STP is to prevent bridge loops and the broadcast radiation that results from them. STP is a protocol. It actively monitors all links of the network. To finds a redundant link, it uses an algorithm, known as the STA (spanning-tree algorithm). The STA algorithm first creates a topology database then it finds and disables the redundant links. Once redundant links are disabled, only the STP-chosen links remain active. If a new link is added or an existing link is removed, the STP re-runs the STA algorithm and re-adjusts all links to reflect the change. STP (Spanning Tree Protocol) automatically removes layer 2 switching loops by shutting down the redundant links. A redundant link is an additional link between two switches. A redundant link is usually created for backup purposes. Just like every coin has two sides, a redundant link, along with

What are the Advantages and Disadvantages of TCP/UDP ?? Difference between TCP and UDP

As in previous blog we have define and explain about what is TCP and UDP and from now we are moving ahead with Advantages, Disadvantages and Difference of TCP and UDP but for this you have to know about TCP and UDP hence to understand it go for a What is TCP and UDP . Advantage of TCP Here, are pros/benefits of TCP: It helps you to establish/set up a connection between different types of computers. It operates independently of the operating system. It supports many routing-protocols. It enables the internetworking between the organizations. TCP/IP model has a highly scalable client-server architecture. It can be operated independently. Supports several routing protocols. It can be used to establish a connection between two computers. Disadvantages of TCP Here, are disadvantage of using TCP: TCP never conclude a transmission without all data in motion being explicitly asked. You can't use for broadcast or multicast transmission. TCP has no block boundaries, so you
