Course Code : BCS-111
Course Title : Computer Basics and PC Software
Assignment Number : BCA_NEW(I)-111/Assignment/2025-26
Maximum Marks : 100
Weightage : 30%
Last Date of Submission : 31st October, 2025 (For July 2025 Session)
: 30th April, 2026 (For January 2026 Session)
This assignment has three questions of 80 marks. Answer all the questions. Rest 20
marks are for viva voce. You may use illustrations and diagrams to enhance
explanations. Please go through the guidelines regarding assignments given in the
Programme Guide for the format of presentation. Please give precise answers. The
word limit for each part is 200 words.
Q1:
a) Trace the evolution of computers from mechanical calculators to the fifth
generation, and identify how each technological shift enabled a new kind of
real-world application.
b) Draw a labelled diagram of the internal data flow in a digital computer and
explain how instructions are fetched and executed using a practical example,
such as calculating total marks.
c) Evaluate the impact of memory hierarchy (cache, RAM, secondary storage) on
the performance of commonly used applications such as video editing or
gaming.
d) Imagine you are designing a kiosk for railway ticket booking. Justify your
selection of input and output devices based on user interaction, reliability, and
efficiency.
e) You have ₹35,000 to assemble a personal computer for online learning and
basic office work. List the hardware components you would choose and justify
your selection based on performance and cost.

Q2:
a) Compare proprietary and open-source software models by analyzing two
software products (e.g., Microsoft Office vs. LibreOffice) in terms of cost,
accessibility, updates, and support.
b) Assume your system has both Linux and Windows installed. Discuss three
scenarios where Linux offers more control or flexibility compared to Windows,
and explain why.
c) Reflect on how compilers and interpreters differ in handling programming
errors. Provide an example where using an interpreter would be more
beneficial during development.
d) Create a scenario (e.g., preparing an event budget) where both a word
processor and spreadsheet are required. Describe how you would use each to
accomplish the task effectively.
e) Design a simple database schema to store student attendance in a classroom.
Mention tables, fields, and types. Also, mention one project management tool
and how it can help in managing a classroom project.
Q3:
a) You have to set up a small office network with internet connectivity. Describe
the networking devices (router, switch, etc.) and topology you would choose
and justify your decision.
b) Suppose you are tasked with designing a personal learning portal. Identify three
internet services you would integrate (e.g., cloud storage, video conferencing,
email notifications) and justify their use.

Q1:
Trace the evolution of computers from mechanical calculators to the fifth generation,
and identify how each technological shift enabled a new kind of real-world
application.
Answer:- The evolution of computers can be traced across five distinct generations,
each marked by major technological advances that unlocked new types of real-world
applications. Here's a detailed look:
1. Mechanical Calculators (Pre-1940s)
Technology:
Mechanical gears and levers
Key examples: Abacus, Pascaline, Leibniz Calculator, Charles Babbage's Analytical
Engine
Enabling Applications:
Basic arithmetic operations for accounting, astronomy, and navigation
Enabled faster and more accurate manual calculations in finance, commerce, and
early science
2. First Generation (1940s–1956) – Vacuum Tubes
Technology:
Used vacuum tubes for circuitry
Machines were large, consumed lots of power, and generated heat
Input/output via punch cards
Key Computers:
ENIAC, UNIVAC I
Enabling Applications:
Ballistics and code-breaking during World War II (e.g., at Bletchley Park)
First commercial applications in census processing and banking data
Enabled batch processing and automation of repetitive numerical tasks
3. Second Generation (1956–1963) – Transistors
Technology:
