Completing BCA and doing a course in animation has no relation in-between.
While BCA is related to programming logic, maths, calculations etc (Science). The animation is something related to ART. I am not sure why you are thinking of doing a course in animation (better job/career prospects or your interest/inclination).
One thing I will advise is, if you are planning for anything related to arts you should have a strong liking for that art, else you will never succeed or enjoy what you are learning or have learned. So, if you are naturally inclined towards art and think animation is something that really excites you, then you should definitely go for it.

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.

Ruby is a powerful, flexible programming language you can use in web/Internet development, to process text, to create games, and as part of the popular Ruby on Rails web framework. Ruby is a scripting language designed by Yukihiro Matsumoto, also known as Matz. It runs on a variety of platforms, such as Windows, Mac OS, and the various versions of UNIX. Ruby is a dynamic, reflective, object-oriented, general-purpose programming language.

1. You must know the object oriented programming principles.
2. You must know UML modeling.
3. Data structure knowledge is must before coding in any programming language.
Eligibility: Bachelor of Technology, Bachelor of Engineering, Bachelor of Science, Bachelor of Computer Application, Master of Technology, Master of Engineering, Master of Science and Master of Computer Application.
Admission process: If you are qualified just look for the right Institute and apply nothing fancy.

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.
