ShikshaTopQuestions-Information Technology

Its depends like,
Yes - If you are the guy who is making his living by clicking "Next" in OS or Software installation.
No - If you are the guy who is making his living by solving real problems (like how to script above actions and make sure they work perfectly in 99.9% of time)
Apart from this, I have a separate view that is 'No'. In fact, cloud computing is creating more jobs. Traditional enterprise IT is moving away from soiled infrastructure with admins managing each of those silos (network, storage and servers) to admins managing software defined data centers (SDDCs) with (hopefully) a single pane of management. The single pane is yet to be realized, but if you are a soiled admin, I suggest you gain expertise in managing the SDDCs holistically.
Quick edit: I guess the old soiled admin jobs are slowly going away, but new ones are being created, where bigger skill set is required.

For a Java developer, having a strong understanding of Object-Oriented Programming is a must.
Master the core APIs- It doesn't matter how strong you are in terms of theoretical knowledge if you don't know the language constructs and core APIs.
Keep coding- Things look simpler when talking about them theoretically. We can give a solution to a problem very easy in theory. But we can realize the depth of the problem when we start implementing our approach. You will come to know the language limitations, or design best practices while coding. So keep coding.
Subscribe to forums -When starting to work on a new technology the best and first thing to do is subscribe to the relevant technology forums. Whatever the issue you are facing, someone else in the world might have already faced it earlier and might have found the solution. And it would be really really great if you can answer the questions asked by other forum users.
Read open source frameworks source code- A good developer will learn how to use a framework. But if you want to be an outstanding developer you should study the source code of various successful, popular frameworks where you can see the internal working mechanism of the framework and lot of best practices. It will help a lot in using the frameworks in a very effective way.
Know the technology trends- In the open source software development technology trends keep on changing.
Know different development methodologies- Nowadays choosing the development methodology depends on the client. Some clients prefer Agile and some clients are happy with waterfall model. So having an idea of various methodologies would be great.
J2EE would be a better choice as its an extended version. So, definitely opt for that.

The scope of CCNA R&S Course in India is dependent upon the track of CCNA Cert you choose. The scope of CCNA certification is quite more than that of CCNA R&S as the security of data is the most important concern for every organization. However, there is not much scope for other CCNA tracks such as Wireless, Cloud etc. in India. However, even if you want to prepare for any Cisco certification like CCNA Security or CCNP or CCNP Security, you will anyhow have to prepare for CCNA first. So CCNA is pre-requisite for all other Cisco courses.
Well coming up to developers, it depends, what kind of Project is the Developer working on, or what he/she aspires for the Future. Having an additional qualification never hurts, only helps at times.
AFAIK, Software Engineers are recruited in major IT MNCs based on their Analytical Ability, Problem-Solving Tactics, knowledge of various Programming Tools & Technologies, Platforms, Debugging etc. skills. I'm not sure where CCNA would fit in.
Besides, CCNA is more into basic Networking the way Cisco delivers it via their own devices. As a Software Engineer if you are trying to get a hang of core Networking, I'd say stick to Andrew Tannenbaum, or Douglas Comer, W. Richard Stevens, etc. kind of great folks.

Individuals interested in working as system administrators or developers should look into training in UNIX. Many certificate programmes combine UNIX training with lessons about the Linux operating system, which is similar in nature. Employers often desire employees to hold a Bachelor's degree, but many hiring organizations will consider applicants with a combination of education and experience or experience and credentials. AIX is a UNIX operating system developed by IBM. IBM offers certification as systems experts, operators, and system administrators for the AIX operating system. The Himachal Pradesh-UX operating system is a UNIX operating system developed by Hewlett-Packard. Certifications are available for administrators at the expert and professional levels. The average salary for a UNIX System Administrator is around 3-5 LPA. The highest paying skills associated with this job are VMware ESX, Shell Scripting, Sun Solaris, and Himachal Pradesh-UX. Experience strongly influences income for this job. Most people with this job move on to other positions after 10 years in this career.
Eligibility - To be eligible for admission into an online training program in this field, students have some experience in IT and/or level of proficiency in programming languages. This is particularly common for admittance to a graduate-level program, which also requires applicants to have bachelor's degrees and possibly prerequisite coursework in math and statistics.
Benefits - Ability to work on server machines that run on Unix, as many software based on Unix; It has a smart set of command line utilities, which does your job faster; Create tools for Unix machines

Linux professionals need a certified course or good work experience on it for employment. However, most employers seek Linux professionals with a formal education along with relevant skills and experience. Applicants most often obtain an associate's or Bachelor's degree in computer science, although other common fields include mathematics or information systems. In addition, some go on to earn a Linux administration certificate. Lab experience may be part of the curriculum. Linux certificate programs offer courses in the field of system administration and information technology. Program lengths vary and may take five to seven semesters to complete. However, some programs allow students up to five years to complete these courses, which often are available online or on nights and weekends. Linux certificate program includes Linux system fundamentals, Linux system administration programming, Essentials of administration, Linux system administration networking, Linux system security, Linux database and Web servers. As technology is changing at a rapid pace and industry needs skilled professionals with 3d - view in technology. The industry is looking for experts in courses like R, Python, MATLAB, Linux and similar newer technologies. Mainly IT companies recruit these software professionals at a good pay.
Eligibility - The minimum educational requirement for a computer programmer is the knowledge in the computer-related area. However, the majority of programmers have a Bachelor of Science/ Technology in Computer Science or similar field of study. Linux programmers should have the ability to administer the manufacturer's systems and work with a variety of programming and scripting languages.
Benefits - It doesn't cost you any money to download and install a Linux operating system. That's great whether you are a hobbyist, a student, or someone getting started on a career as a programmer. It costs nothing to learn Linux and upsides are plenty. Whether youre managing a companys server or helping to build the cloud services that clients increasingly rely on, employers want people that know how to use Linux.

Python is the older of the two languages. In programming language evolution, it is common to maintain backward compatibility indefinitely. This is not the case with Python. Python versions are largely compatible but have enough functionality- and syntax-breaking differences that they can be treated as different languages. Python is adapted because of Simplicity, Open source, object-oriented and General purpose language. It is an interpreted language available on many platforms, making it a portable option for general development.
Java on the other hand
Its attraction and value is its portability and relative efficiency. Java is a compiled language, unlike C/C+. Its execution model is more machine-centered than purely interpreted languages. Java is more than just a language and libraries. It is also a virtual machine and, therefore, an ecosystem. The Java Virtual Machine (JVM) is an idealized and portable platform for running Java code. Rather than worrying about hardware specifics and having to port code to new platforms, the promise of Java has been written once, run anywhere. That is so that as long as a JVM is present, anything compiled into its bytecode can run and interact easily with anything else written for the JVM.

Perl is a programming language developed by Larry Wall, specially designed for text processing. It stands for Practical Extraction and Report Language. It runs on a variety of platforms, such as Windows, Mac OS, and the various versions of UNIX. This tutorial provides a complete understanding of Perl. Prior knowledge of C/C++ or UNIX shell programming is preferred for Perl programming. Courses for Perl developers may include computer systems, algorithms, data structures, machine architecture, software engineering, linear algebra, and discrete math. Because Perl is a dynamic programming language that differs fundamentally from languages such as C/C++ and Java. There are many online courses available for Perl on Udemy, Lynda, Coursera etc. Check the below link for institutes offering Perl courses - https://www.shiksha.com/it-software/colleges/perl-colleges-india
