Which is a better engineering field: computer science or electronics and communication?
This question arises among most of the high school students , waiting for seat counselling dates.Well both CSE and ECE are really good branches. I will try to give, what type of person likes a particular branch. You are the person, who needs to choose the career path. I will share my experience as an ECE graduate and working in core company and my besties from CSE.ECE is electronics and communication engineer in India and electronics and computer engineering outside. In this, you will be having all electronics based subjects. Most of the subjects will be common with CSE, like electronic devices and circuits, computer org, operating systems. Embedded sys ,vlsi ,C, microprocessors. ECE deals with computer hardware and also electronics circuits . If you are taking electronics, then you need to make your mind to do calculations each and every time. You will be having Antenna stuff in some semesters, these are really tough to learn. Even you are not interested you need to pass them. If you are good at physics and mathematics you can take ECE. Even average in mathematics is good. You can improve. Many take IT jobs without trying hard, this is because of 3- tier colleges in India and poor staff ,who fail to teach concepts properly.CSE is really good subject and many feel it easy than ECE. As this is a branch of engineering and closely associated with hardware, you will have to learn some hardware subjects as mentioned above. I saw my friends from cse cursing university for introducing those subjects and arguing with me on benefits. This is because of making you to know, how a hardware is designed and basics. As you will develop software. CSE is not just software job as in India. It's more than that, cognitive sciences, Neural networks. But, here we dream of IT job. That's not correct. If you are so passionate in neural networks and Cognitive science, do not stop with job. Go abroad and do research. This suits for most of students due to less mathematics involved.Decision remains in your hand. If you take a beach, try to work in same field, improve knowledge, read journals. Be successful.
Which is better: BSC in computer science or a BTECH?
Thanks for A2A. B.Sc. Computer Science is 3 years of Graduation course while BTech is 4 years of Graduation course after which you will get Engineer's Degree.Benefits of B.Sc. Computer Science:If you have some Social responsibility (like financial issue, family need or relocation issue) and you would like to finish your graduation as early as possible then you may select B.Sc as it will be completed in 3 years instead of 4 years in case of B.Tech. Also course contents and syllabus level is somewhat easier than that of B.Tech, so you may spare some good amount of time for other responsibilities or commitments. Fees are less compare to B.Tech course.If you are specifically interested to study computer science and you are not getting admission in B.Tech Computer Science (or similar type of branch as CS) then you can go through BSc CS where you can learn your interested kind of subjects. Moreover after completion of BSc CS, you are eligible for applying in MCA (which can be considered as equivalent to B.Tech CS) If above If... are not constraints for you then I would like you to go with B.Tech. Benefits of B.Tech.: You will get more technical exposure in B.Tech. compare to B.Sc. CS. Moreover, First year of B.Tech course comprises of Basic knowledge of various Engineering fields like Mechanical, Electrical, Electronics, Civil, Computer, Mathematics, etc. Which can be very helpful in your career.If you get selected for B.Tech in CS then undoubtedly you will be getting better course contents and deeper knowledge of Computer science and its subjects. B.Tech will offer wide career options and decent future than B.Sc. CSIf you get admission in a good B.Tech college / university then you will be having a good platform to develop your technical skills and knowledge at State or National level; if you are capable enough.My personal vote goes for B.Tech but, situation and view are different for person to person. So you have to decide what is better for you. If you put your best efforts in study and if you really deserve then I believe any of above courses will offer you a bright future. All the Best
Help with physics (electronics) please?
I studied electronics theory for a long time, here's what I can do for you...... 1) The graphs are needed if the EMF is D.C. voltage (then it starts to get complicated explaining a DC charge circuit for inductors/capacitors) Use the following formulas to find the missing variable for EMF of A.C. voltage. Algebra is a must here. XL= 2 times (pi) times f times L : Xc=1/[ 2 times(pi) times f times C ] XL is inductive resistance (in ohms) Xc is capacitive resistance (in ohms) f = the frequency of the A.C. power into the circuit (in Hertz) L = the inductance of the inductor (in Henry's) C = the capacitance of the capacitor (in Farads) - should be a very small # pi = 3.14159 2) No. The R/L constant is used for D.C. charging. D.C. voltage doesn't have a frequency. 3) You have one of the correct answers here. Adding a capacitor will change the voltage by reducing the rippling effect to a higher constant. The other answer is the change the configuration of the diodes (using fewer). This will also - CHANGE - the voltage since you can configure it to a half-wave or full-wave by re-orientating the diode configuration. Your teacher/instructor may make the argument that it's not a bridge circuit anymore. OK I could see that - BUT what if one (or more) of your diodes frys out due to current overload ?? - This is basic troubleshooting.......... I've seen it before in the field, doesn't happen often because engineers "usually" take this into consideration in the design. 4) I'm not familiar with the 74LS08 AND gate. This is a question that an engineer can help you with, I deal in the real world. IC chips come in a wide variety due to the number of different suppliers of the parts. What is good enough for one manufacturer may not be good enough for another. That's why they have spec sheets (if your employer actually bothers to keep them around - the right ones, I mean) Another point that's good to keep in mind is: that specs on the same IC chip can change even if they come from the same manufacturer. I can't even remember how many of those little buggers that I spent the afternoon changing out because of a bad/underrated batch that got sent to our company, because of somebody at QC.
What could you do with a double major in computer science and physics/aerospace engineering?
It's always best to major in the subject you love the most. For me its BSAE then planetary science or MSAE, but that is me and I'm the type of person who values the knowledge of space like others value or put faith in religion. If you are starting to become more interested in space (and what science major wouldn't be), consider focusing your programming electives towards electronics/robotics programming or similar courses offered at your school. Most defense and hi-tech companies hire more programmers and electrical engineers than any other engineering discipline. Those two majors have no overlapping courses like other engineering majors. The curriculum for physics and aero even differ greatly. Physics is involved in every aero course, but a physics major generally focuses more on pure physics (quantum mechanics,fields/waves etc.. ), aero is more focus on a broad range of aerodynamics and aerospace structures. Dual majors are often not as impressive or desired as much as a single graduate degree. Most employers see a masters degree in physics/engineering as a degree that shows the applicant has lab and or research experience. Undergrads fresh out of school often need to be told what to do when they are hired because all they have seen so far is the inside of a classroom. Over 70% of the people working at Nasa facilities do not even work for Nasa, they are usually employees of companies like United Space Alliance, ATK, Lockeed, or other large defense contractors. As history has show, Nasa funding goes up when republicans are in office, and down while democrats are in office. The Obama administration is no different, funding cuts are already underway. Engineering students are generally given a mentor/adviser that can help them make these decisions. Ask your advisor what you asked on here, and see what he/she says. Good luck, Math and Science is the way to go.
Anyone please help me i got unexpected compartment in physics (cbse class 12) and i am feeling suicidal......?
I failed in Physics and don't know how to give compartment paper(don't know how to apply for it) i have taken tc from my school which is in Jalandhar city and my parents have shifted from jalandhar city to patna. i can't go to my school. and cbse help line no are always busy and school at patna are not responding to my query. I am Totally depressed and don't know what to do know next. and on the top on it i am fighting with myself on this bad feeling of Suicide and it is going stronger and stronger. Previously i have question why people commit suicide now i thing i am very close to get the answer or may be i got the answer. I am not going to die sooner but if you can help me then please help i appreciate that.
Is physics a major part of computer engineering?
You need to take physics classes as part of the major, but luckily there are really only 2 calculus-based physics classes that you need to take: Newtonian mechanics and Electromagnetism. They are only the 100-200 level ones, so the calculus involved isn't any more in depth than your first calculus class, except for electromagnetism they may make you think in 3 dimensions (but you don't have to do any actual multivariable calculus, just try to take in the concept). The only thing from the physics classes you will actually use will be for a fundamental understanding of circuit theory, which you will get in a lot more depth in computer engineering classes. You will have to take advanced math, which many students say is worse to learn than the physics. You will be required to take 2 semesters of calculus, plus linear algebra and ordinary differential equations. Understanding linear algebra greatly helps solving circuits, and understanding differential equations is paramount to signal processing. You will also have to take a number of engineering courses that you may not want to take, but concepts from them will pop up in job interviews. You will have to take an elementary electromagnetic waves or transmission lines class, which describes circuit behavior when you throw out the assumption that everything happens at the same time (voltage moves as a wave). This is really important any time you want to send information at a high speed further than a few feet. You will also have to take a circuit theory class (maybe 2, depending on the university) that covers generally how circuits work and how to design some pretty basic ones, both DC and AC /signal processing /audio stuff. The circuit theory class is often described as a "weed-out" class. You will also have to take a class on electronic circuit design which explains how diodes and transistors work as switches and amplifiers, and the class is also often described as a weed-out class. You will have to take a few computer science classes, which I'm sure you're looking forward to. You will also have to take classes that go over digital system architecture and computer system architecture, and you will probably have a choice between taking an operating systems class, an embedded systems class or a digital chip layout design class (digital VLSI). Plus, signal processing involving Fourier transforms and lots of differential equations.
I just passed class 12. I didn't have computer science as my subject and had biology instead. Is there a problem if I study a B.Tech in CSE?
The first year at any engineering college comprises of a coding language in its curriculum.The course would provide you with essential basics of the coding language but the problem does not lie there.The students who have already studied any coding language would be the real cause for your misery. Although teachers try their best to balance the class but it generally favours the ones who already have the coding knowledge and the reason is fairly easy to comprehend,continuous interruption in lectures, throwing questions at teachers(some smart ones try to even test the teachers) which will leave you in perpetual bewilderment and generally hinders your grasping of the subject.Our teacher came up with a brilliant idea, she seperated the classroom in two parts-CODERS(80%)NON CODERS(20%)What she did was that even when she discussed some of the very basic topics she would throw some of the toughest question to the remaining coders(and constant involvement in questions reduced the nuisance for others upto an extent).So she explained the concepts to the other students (non coders)while the ones who already knew (coders)had some thinking to do.So both of the sections developed,one learnt the concepts and some time later even started solving tough problems and the other section revised.Finally what happened was there was development on both the ends.You should try to convince whomsoever teaches you in your college to teach in this manner. It would really prove prudent for your understanding of the subject alongwith reduced hinderances.
To pursue a career in astrophysics/cosmology after a B.Tech. Which is the best course to opt for in a B.Tech: CSE or ECE?
Astro-physics is a PhD level achievement. no ofrence, but things change a lot if u start thinking tAbout becoming an astro physicist from the level of bachelors. It's a very tough, renowned and one of the most interesting fields. I'll take u through a round about of how to become an astrophysicist, taking a consideration u have done good in every level. takes science in school engineering in bachelors, ,out probably something like mechanical,electrical or optical would help. Or u take BSc, in physics. U do master in Physics or whatever engineering department u have chosen. U give a phd in physics and go for astro specialisation. Truly speaking, in this fled, if u attain one PhD, u will never be satisfied. U should have at least two PhDs, to get phone calls and be in demand by space body authorities and other places.mthe job u get basically from this field is, either a teacher who teaches and mostly spends time in his own research or are hired by NASA or ISRO like body for calculations. If u are extremely lucky, and extremely good and fit, u might hit the chance to go to space as we'll.in any circumstances, if u are sure and totally sure you would become an astro physicist and won't change your mind I think the better way then is by taking B.Sc in physics or if u are not sure, then take engineering and pursue it. I feel engineering is a better way , cuz keeping option of in life is a better way of progressing. If any further questions do let me know.for which engineering you should be doing. It really doesn't matter, cause engineering involves physics throughout till the time u opt only for computers. So do any engineering which involves physics, cause astro-physicists are all about their PHYSICS.
How do I get admission for an M.Tech in physics after doing my B.Tech in computer science?
yes it is a possibility. if u clear gate then when you apply for m tech u can change you branch. so lets say your branch is cs and u clear gate by giving CS gate paper then when you apply for m tech u can choose physics.
