BSc Computer Science: The Ultimate #1 Guide with All You Need to Know

B Sc_Compute_Science

B Sc Computer Science, which is a Bachelor of Science degree in the field of Computer Science (Bachelor of Computer Science), still stands to be one of the most popular degrees. Eligibility for B Sc Computer Science programs varies from college to college but will typically require you to complete Class 12 boards with Physics, Chemistry and Mathematics or at least with Mathematics. B Sc Computer Science points at a variety of job openings in the software and IT industries of today, with multiple opportunities in India and abroad mostly after post graduation& higher qualifications.

B Sc Computer Science: Introduction

B Sc Computer Science is typically a 3-year long program. B Sc Computer Science syllabus covers all aspects of computers right from the basic fundamentals of computers.

Basic fundamentals include

  • All functions of computing devices
  • How they operate through high level/low level/ assembly languages
    • High-level languages (HLLs) are the ones that programmers use for coding in modern times. C++, Java, Python, Perl, Ruby, etc are all examples. Anyone or a combination of these can be used to build software.
    • All HLLs are broken down into assembly languages first. These are simplified versions of the HLLs. Assembly language uses both alphabets and numbers and some special characters like # (hash) \ (backslash)etc.
    • Assembly language codes are further broken down into machine code.
    • Machine language is the only one the machines understand. All computers in the world operate on machine language. Machine language is a sequence of 1’s and 0’s only, no characters, no letters and no other number.
    • So the HLLs and assembly codes have to be translated to machine language and then the computer does what the code asks it to do. This is called the ‘execution of the code’.
    • For an example, if you want to print “Hello World” on your computer screen, you write the program in C++ (suppose), then the computer converts the program (of 2/3 lines) to assembly language (simplified version; several lines) which is then translated into a string of 1’s and 0’s (machine code; many more lines). After this, the computer actually prints “Hello World” on the screen (execution of the print command in this case)! All of this is done in less than half a second.
    • So the first few stages are just about translation from one language to the other. The translation is also done by the computer itself but it does not perform the ‘printing’ function (in this case).
    • Assembly and Machine language systems, hardware-level processing are hardly given emphasis at undergraduate degree level syllabi across colleges. Programming with HLLs and other associated technologies receive maximum proportion.
  • Discrete mathematics – involves higher mathematics, calculus and statistics mostly, Class 11-12 level onwards
  • Electronics and Semiconductor Physics: this deals with how the electronic circuits, the memory of a computer, etc works after the HLL code is converted to machine code or object code (also called binary code). The final execution of the code is carried out by the electronic chips inside the memory of a computer.

Most of the course is taught using popular in-demand programming languages like C, C++ and JAVA.

Note: Every programmer today uses any one of the high level languages to write codes (C++ and Python are the most popular). HLLs can also be used in combination.

‘C’ is almost obsolete.

Codes can also be written manually in the low level languages but it is a very very lengthy process and hence the HLLs were invented. HLLs are written by humans and translated into assembly/ machine by computer. HLLs are converted to low level languages (to both assembly and machine) by a computer itself. When translation till machine level is reached, the computer executes a task because it only understands machine language.

Every computer uses machine codes without which it does not run.

C++ is taught at Class 12 levels too and is highlighted as a good first language to learn.

Fundamentals of B Sc Computer Science: How a Computer Works
Fundamentals of B Sc Computer Science: How a Computer Works

Step 01

Computer programs, called the “source code”, are written in high level languages (HLL). Human programmers write these source codes in HLLs

Every programmer today uses any one of the high level languages to write codes (C++ and Python are the most popular). HLLs can also be used in combination.

For an example, if you want to print “Hello World” on your computer screen, at Step 01 you write the program in C++ (or any other HLL)

Step 02

Source code goes through a language processor which may be a compiler or an interpreter or a combination of both.

As per the example, your C++ HLL script to print ‘Hello World’ will go through the compiler at this Step 02

Things to remember at this step
  • All computer programs/ source codes mandatorily have to be converted to machine language in order to be executed.
  • Machine language (sequence of 1’s and 0’s) is the only one that computer hardware understands through logic gates.
  • Logic gates detect the presence or absence of electricity (1 means presence and 0 means absence).
  • All source codes are either ‘compilable’ or ‘interpretable’.
    • The source code when ‘compilable’, is driven into a ‘compiler’ that converts the entire code “all together” into machine language. It converts the whole code into machine language at a time.
    • The source code when ‘Interpretable’, is driven into an ‘interpreter’ that converts the source code “line by line” and not altogether like a compiler.
  • Some high level scripts (languages) like Perl, Python etc need an Interpreter and not a Compiler to convert those scripts.
  • On the other hand, C, C++, JAVA are compilable.
  • Every programming language has its own inbuilt compiler or interpreter.

Step 03

The processors (compiler or interpreter) ‘processes’ HLL codes or source codes and turns them into machine language (object code).

Processors break down the source code (written in HLL) into machine language (easy for a computer to understand), a sequence of 1’s and 0’s.

Source code is turned into object code at this step.

As per the example, at this step 03, the compiler will convert your C++ script adding many more lines to generate the machine code or object code (sequence of 1’s and 0’s).

Step 04

The object code in machine language (a sequence of 1’s and 0’s) goes into the computer hardware (electronic circuitry containing logic gates). Hardware understands the ‘object code’ in machine language.

As per the example, at this step 04, the hardware and logic gates understand the object code (sequence of 1’s and 0’s), which was converted from your C++ source code. By ‘understand’, we mean it decodes the program into the presence and absence of electricity. 1 means presence and 0 means absence.

Step 05

Hardware gives us an output such as an executable file or another program or simply text etc.

As per the example, at this step, the computer actually prints “Hello World” (simply text) on your computer screen (execution of the print command in this case).

All of this occurs in far less than half a second!

Things to remember at this step
  • If the source code has some error in it or is not thoroughly compilable or interpretable internally, we obviously do not get output or are showing error messages and lists of errors, etc.
  • The errors must be removed from the source code before it can successfully be recompiled or reinterpreted again.

What You Must Know: Bachelor of Computer Science (B Sc Computer Science) Vs Information Technology

CS vs. IT

A laptop, a Kindle, a mobile phone, a camcorder, Microsoft Office Suite, search engines like Google Or DuckDuckGo, Windows Operating Systems, a Wireless Fidelity (Wi-Fi) Network, a Tata Sky TV box, a GPS unit, scientific calculators, a social networking site, a payment transaction service, are all examples of IT products and services.

All these IT products and services are designed, developed, and programmed by Computer Scientists and installed, tested, run, and maintained by IT professionals as well as Engineers from other disciplines.

Understand that in the game of IT vs Computer Science, job scope wise, there aren’t many differences. In most companies today, both Computer Science and Information Technology degree holders can work in the IT industry.

However, an IT career doesn’t necessarily require a Computer Science (CS) degree, although a CS degree opens certain doors that otherwise would not be available.

Computer Science is the scientific & practical approach to computation, programming and other applications. That means they understand the “why” behind computer programs. It also includes abstract concepts like computational complexity theory.Information Technology refers to the hardware, software, products & systems that result from the work of Computer Scientists and researchers from other associated disciplines linking aspects of engineering, science and mathematics.
Computer Science is the study of the principles of computing and how computers solve problems. Whereas, IT is the study of current tools/ computing techniques that can be used to best meet technological needs of a particular organization to bring out a desired effect or develop a product of the company.Information Technology (IT) as an academic discipline which mostly deals with industry-oriented learning whereas Computer Science (CS) is more research-oriented. You may say that, Computer Scientists design tools and Information Technology professionals apply these tools.

Bachelor of Computer Science (B Sc Computer Science) Vs Information Technology
Bachelor of Computer Science (B Sc Computer Science) Vs Information Technology

Most of the top-notch institutes (including all the IITs, IIITs, BITS and most NITs) have either Computer Science & Engineering or Information Technology but not both.

The difference between the two branches is not significant enough to warrant their simultaneous presence on campus at least in the eyes of the top engineering colleges of the country.

Further, for the few colleges that do offer both CSE and IT(Computer Science & Engineering and Information Technology), the difference in the course structure is minimal. Moreover, students from both branches are employable in the same set of industry sectors. Recruiting corporations make little difference between these disciplines while selecting students.

B Sc Computer Science Scope: Future Prospects

B Sc Computer Science courses have a great structure in terms of learning outcomes possibilities. You will get to study new topics that are in demand these days including core mathematical concepts of AI, Machine Learning, Database Management Systems, Neural Networking, and Natural Language Processing, mostly as electives.
Most students, however, make it a point to pursue post-graduation courses and then join the industry since prospects right after graduation is a bit blurry. After graduation, you may pursue M Sc in Computer Science, MBA, or MCA which are promising options for lucrative offers in the software and IT sectors.

Some IITs have integrated M Sc programs in Computer Science right after school. However, entry to these programs is governed by IIT Advanced exam scores. You can think of other prestigious institutes for your post-graduation (after completing B Sc Computer Science from somewhere) like Chennai Mathematical Institute (CMI), NIT Trichy, BHU etc which conduct their own entrance exams for MSc in Computer Science.
The figure here depicts the growth estimates of associated industrial sectors.
