CCNA

Lot of private computer training institutes offer computer hardware and networking courses. You are advised to join networking engineering course. Once you have completed course you may appear for CCNA Certification exam conducted by CISCO.

Hi,
Yes, you can do CCNA after H&N. However, if would like to stick around networking then CCNA is a good choice. Also, if you want to settle your career in systems then MCSA, MCSE would help too.

Hello Akash,
Linux is a "must-know" for anyone interested to work in IT department. Linux is an operating system and provides sufficient tools which assist in advanced programming. On the other hand, CCNA is a networking course certified by CISCO. This course is recommended for those who wish to make make a career in the networking field in the IT sector. Ideally, I would suggest you to pursue both the courses as both are equally beneficial. Rest is your choice.
