Major requirements coming from Financial Services firms, Retail and FMCG organizations, Investment/Retail Banks and NBFCs, Healthcare organizations, and Market Research firms. Companies are offering job roles like - Data scientist, Analyst manager, senior data analyst, Business analyst, Analyst consultant. 10 leading organizations with the most number of analytics opening this year are Amazon, Citi, HCL, Goldman Sachs, IBM, JPMorgan Chase, Accenture, KPMG, and E&Y & Capgemini. These companies are paying heavily for Data Scientist with proficiency in R-programming. Average pay scale is from Rs. 4-8 LPA. For Post-Graduates, it is even higher. It starts from Rs. 14-15 LPA.

Unix shell scripting profile: there remains a shortage of experienced professionals in the market. There are unlimited career advancement opportunities for developers and systems administrators who are skilled in Unix Shell Scripting. Few job roles that you can bag with Unix skills are:
Systems Engineer- Unix/ Linux
Software Engineer
Unix/Linux Engineer Job
System Administrator
IT companies like TCS, INFOSYS, Capgemini, WIPRO seeking IT employees with training in Unix Shell Scripting.
Shell Scripting languages is ranked No. 14 among the 25 skills that can get you hired in 2016 by LinkedIn, Unix and Shell Programming, are among the top skills that employers are seeking in their prospective employees this year. Unix skills can also help IT professionals diversify into top-paying fields such as ETL Development/Testing, Big Data & Hadoop Development/Testing, Java Development/Testing, Unix SQL Production Support, and many other areas.

Both are best choice, and CCNA & RedHat are equal, but remember Cisco is Networking and RedHat is Linux , Cisco is a closed source and RedHat is open course, that's why Cisco has very good and much better revenue. If you did both or any one certification, you will be definitely getting a better job.
If you are interested in server side networking, then you can go for RedHAT. It is the best suitable course.
If you are interested in core networking, then you can go for CCNA, CCNP, CCDA, and CCIE.
RedHat course has an edge over CCNA, as it has links to Linux, which is widely in use in an IT-Industry, and there is need of such specialized professionals. Linux is very vast and it is growing more rapidly than network. It doesn't mean just after getting certified, you'll get huge salary and designation. It totally depends on your experience and knowledge on linux-RedHat. You can expect good job offers in IT/IS based companies with initial salaries of Rs. 2-3 LPA.

Hello,
A very interesting query has been posted. It requires solution in all dimensions. Firstly, and most importantly M.Tech and MCA are considered as almost same by many in the industry. But, this is far from truth. Though of course, both are post graduate courses. Pursuing M.Tech is possible only if one has completed B.Tech or BE in relevant field. Only after this, admission is feasible. Then, there is GATE that one needs to clear before admission could be thought of.On the other hand, pursuing MCA is possible based on marks obtained in BCA at graduation level. Having said this, it is observed that many subjects are common between these two streams and students who are pass out are having good domain knowledge about softwares. To conclude, I would say that there is no need to do M Tech after having done MCA.

Cisco Certified National Associate is the most common exam for IT certification in computer hardware and networking field. Exam is organized by Cisco under collaboration with Pearson VUE certified by CCNA. Exam is of 45 to 55 questions in the time duration or 90 minutes. Exam is available in English, Japanese, Spanish, French, Portuguese and Russian.This exam has questions of various patterns such as multiple choice single response, multiple choice multiple answer, fill in the blanks, drag and drop question and simulator question. So before appearing in the student must have to go through previous year question paper and mock test paper as there are different types of question asked in exam so more and more practice is needed before appearing in the exam.

There is a distinct difference between a degree and employability. Degrees are the base, it is something you build upon throughout your career. It is not just to clear the criteria but so that you can have your fundamentals in check.So, there shouldn't be any conflict as to whether a certification can supercede or substitute a formal degree or graduation. CCNA or Cisco Certified Network Associate is a base level certification to get into the world of networking. But, if one tries to find a job with this certification alone, it is going to always be a futile search.
I don't know of any company which would employ a 10+2 with a base certification. More than that, the candidate himself/herself won't be able to adjust to the technical terms and understand the course without any basic technical knowhow. Therefore, a graduation is a must. This certification can be used to add to that and get a more stable job focusing on the long run.

Hello,
Assembly level Languages are low level programming language for microprocessors and other programmable devices. This isn't a single language, rather is a group of languages targeted towards a specific CPU architecture. It contains symbolic representation of the machine codes for the target CPU infrastructure. Unlike High - level programming languages like C+, Java, .NET, etc., these programs can be ported to only those systems which have the same CPU architecture.
Understanding of basic programming languages like GWBASIC, C, etc. would serve as an added benefit to understand Assembly level programming as these entire use top - down approach.
Though Assembly Languages are used these days only in companies which design microprocessors and other programmable devices, it does find an extensive opportunity in security devices, which involve output of hard-wired encrypted messages from those devices. Also, it does find massive employment in the field of Artificial Intelligence to design smart devices.

Hello,
A shell is an interface between the user and the services of operating systems. In UNIX or other Linux based operating system, shells like bash and korn support programming construct which are saved as scripts. These scripts become shell commands and hence many Linux commands are script. Typical use of a shell script would be to automate what is required and present it in a desirable manner.
Generally scripts can be used to achieve several tasks. Listed only a few:
1. Create your own command/tool
2. Monitor several tasks like disk usage, etc.
3. Taking data backups and snapshots
UNIX and mostly the LINUX based Operating systems are used mainly for development purposes. Right from networking systems, to applications are developed in LINUX based operating systems, and is preferred by programmers. Shell Scripting helps to achieve certain functions that are not included by default. These are mostly used to configure the server or the administrator system in a network.
To option for this, a person needs to have basic knowledge of the functioning of an operating. This involves, knowledge of the layers of the operating system, the interactions between them, and the boundaries involved.
It forms a small part of network configuration and administration. Hence, this course should be pursued as a part of network management course.
