In general, the protocols are guidelines which lay down certain rules. These protocols describe the movement of data between the source and destination or the internet. These protocols offer simple naming and addressing schemes. Currently, In India, there is no particular college (or institute) providing a full/fledged course in TCP/IP. You can learn this while studying network engineering. The required skills to apply for the job of TCP/IP are: you need to be experienced. Experience with Cisco Systems IOS routers and switches and ASA firewalls or experience with TCP/IP, routing/switching concepts and common routing protocols. You can do B.Tech in IT to be eligible for jobs. Thank you.

If you take FPGA used for implementing DSP applications, you need knowledge of DSP algorithms. But the challenge is more towards designing the hardware than writing algorithms for filters which is not tough as there is a lot of references already available. Most of the engineering jobs related to DSP do not actually require that much mathematics which is generally taught in the curriculum. There is more expectation of writing C/MATLAB synthesized codes. So yes, to an extent the challenges seem to be more in RF for communications or designing chips for it. However, if you pick up Machine learning and focus more on algorithms, then your spectrum as a DSP engineer will widen drastically. Also, there is scope for DSP in communications but the current trend is not good for these companies. Thank you.

The role of ethical hackers is to check the vulnerability of the system's software from foreign attack. An ethical hacker is a computer and network expert who attacks a security system on behalf of its owners, seeking vulnerabilities that a malicious hacker could exploit. These types of hacking is said to be ethical because this hacking is done by the consent of owners to check its intrinsic and extrinsic security. According to the report by CNBC, India requires more than 150,000 ethical hackers, but currently, India is able to produce 25000 -30,000 only. Since today's unethical hackers are more qualified and trained, you also must have to be skilled to cope with them. An ethical hacker also should have a basic understanding of TCP/IP protocols such as SMTP, ICMP and HTTP. To conclude, there is huge demand and need of Skilled Ethical hackers in India. Provided you must have to choose your success path wisely. Thank you.

They can work in the research and development department of firms such as the Defense Research and Development Organization (DRDO), Electronics Corporation of India Limited and National Intelligence Council. They can seek employment as Junior Research Fellow or Senior Research Fellow in IITs or IIsc. A fresh graduate can also work as management trainee in such organizations. Private firms offer plenty of job opportunities for such candidates, where one can work as Application Consultants, Field Application Engineer, Design Engineer etc. Some of the popular firms are:
1) ARM embedded technologies
2) Alliance Semiconductors
3) TCS
4) Texas Instruments
5) Transwitch
