Best Answer: Choose embedded system, if you wanna do some assembly/machine language programming. Choose Networks if you are interested in Communications and protocols, from your syllabus it seems they have just theory and concepts, so lot of text to learn in this case. Neural networks have some complex and advanced algorithms helpful in data mining and clustering, it is also an interesting subject but with lot of maths and algos. If you advance in computer networks you can do CCNA etc easily embedded system is helpful if you wanna pursue your carrier in electronics neural networks can help you land in very good software companies such as oracle etc.( I would choose this if I were you!!) All the best. - kashyff

Hi, Well, what can I say. Being 48 yrs old and a real time embedded software engineer I think you can guess my answer. I started out in life armed with a degree in electronics way back in 1982. The 8-bit microprocessors, ( my handle Zilog32 gives a clue! ), were all the rage then and digital electronics was growing up fast. CMOS logic was fast replacing TTL. Fabbo times!!! But I soon found myself writng assembler for the micro systems I had desgined and so in 1990 I took a masters in Computer Science and Applied Mathematics. I actually learned my first 'high level language' - C - on a DEC-PDP11. Ha ha. Anyway, because of my electronics background I found myself getting more and more involved in embedded systems - yes eeproms etc. However, with the great rise of internet technologies I studied and designed web based software in HTML/DHTML, Javascript and PHP. C++ being with me since its first official release. Funnily enough C++ was not accepted much amongst real time software guys - mainly due to its huge memory requirement but things have changed with progress and technology nowadays. The advantages of having the internet technologies and embedded systems 'under my belt' has proven to be a great asset as regards work. I have been freelance for the last 12 yrs and are never short of work/contracts - even in these difficult times. The 2 technologies have now come together - take the iPod and iPhone for example. So I have the best of both worlds. I'm sorry to have bothered you with a bit of nostalgia but try to remember that whatever your choice there is a wonderful adventure out there awaiting you so enjoy and look forward to it my friend. Sincere best of luck. Ges Scott ( aka Zilog32 ). PS The alias actually refers to the Zilog 8 bit microprocessor I used in my first ever design - a conveyor belt weighing system for measuring weight and flow of coal coming out of a coal mine!! The 32 refers to the last Zilog micro I worked on!
