Course comparison

There is a difference between IT and ICT and Its simple as a piece of Cake.
In IT the word I relates to Information that is in forms of ZEROs and ONE, binary so every subset of IT that is Infrastructure (network, server), Information System (application, databases), Information Security (access control, firewalls)are all deals with data in the form of Binary. In short its all about binary data.
In ICT , I relates to Information which can be analog or binary and Communication relates to devices which sends and receive signals, Its all about device technologies which communicate with each other such as radios with station, mobile with tower, TV with the help of decoder, even satellites. Its all about transmission services.

Both M.Tech and MBA are good career options after engineering graduation degree. M.Tech will make you a specialist in chosen field and you can make career as a technologist. You may seek admission in M.Tech if you are technically inclined. If you are not technically inclined then you may opt for MBA and become a generalist. Currently scope of MBA is wider but slowly industry has started paying good salaries to technologist also. Number of opportunities for Government job are restricted and also slowly government is rationalizing its term and conditions of job. Life time pension benefits were withdrawn by government in 2004. I am not in favor of graduate engineers doing a government job below class I officer. If you able to get job of class I officer in Government after engineering then its a good option otherwise it is not a good option. My recommendations in order of precedence for your choices are as follows: M.Tech, MBA and Government job.
