BCS 111 Computer Basics and PC Software is the 4-credit Semester I theory course of the IGNOU Bachelor of Computer Applications (BCA_NEW and BCA_NEWOL), and this file answers every part of its June 2026 term-end paper. Two answers are open on this page; the full file answers all 20 parts.
1. What the June 2026 Solved Paper Covers
This file is built on the official paper that IGNOU printed jointly as BCS-011/BCS-111 and labelled BCA Old/New. That means old BCA students on BCS-011 and new BCA students on BCS-111 faced the same 5 questions, split into 20 parts, for 100 marks in 3 hours.
This paper leans hard on arithmetic and networking. You get a magnetic tape density sum, a courier data speed sum for a 1 TB disk, and a 20-bit machine instruction built from a 4-bit opcode. Alongside those sit switches and hubs, repeaters, VPN, twisted pair cable and the full DNS lookup process.
The software side is just as specific: a linker diagram, performance enhancement utilities, two ways to print one line five times, a while loop for even numbers, the three pillars of OOP, and ASCII against Unicode. If you are also collecting the BCA_NEW Question Paper set for Semester I, this is the one that tends to catch students on the numericals.
2. Two Answers Solved in Full, Eighteen Held Back
Two answers from the June 2026 paper are shown here in full, Q1(e) on tape recording density and Q3(b) on DNS, and the remaining 18 parts are answered only in the paid file.
We picked these two because they show both sides of the paper: a numerical where every step earns a mark, and an 8-mark theory answer where the examiner wants a clear sequence.
Recording density of a magnetic tape
Question 1 (e): A magnetic tape is 1 metre long. What must be the recording density of the tape in bytes/inch, if its storage capacity has to be 50 MB? (Take 1 inch = 2.50 cm) (6)
Answer: the tape needs a recording density of 1,310,720 bytes per inch (1.25 MB per inch) to store 50 MB along its 1 metre length.
Step 1: convert the length into inches
Length of tape = 1 metre = 100 cm. Since 1 inch = 2.50 cm, length in inches = 100 ÷ 2.50 = 40 inches.
Step 2: convert the capacity into bytes
In computer storage, 1 KB = 1,024 bytes and 1 MB = 1,024 × 1,024 = 1,048,576 bytes. So 50 MB = 50 × 1,048,576 = 52,428,800 bytes.
Step 3: apply the density formula
Recording density = storage capacity ÷ usable length = 52,428,800 bytes ÷ 40 inches = 1,310,720 bytes per inch (BPI).
Check: 1,310,720 × 40 = 52,428,800 bytes, and 52,428,800 ÷ 1,048,576 = 50 MB exactly. The answer can also be written as 1.25 MB per inch, because 1,310,720 ÷ 1,048,576 = 1.25.
Assumptions worth stating in the exam: the whole 1 metre is used for data, with no leader tape and no inter-record gaps. On a real tape, gaps between records waste some length, so the actual density would have to be higher than 1,310,720 BPI to hold the same 50 MB.
Why bytes per inch works for tape: on a parallel track tape such as the classic 9-track format, each byte is written across the tracks as one frame (8 data bits plus 1 parity bit). So one frame per position along the tape equals one byte, which is why tape density is quoted in bytes per inch. If your examiner takes 1 MB as 1,000,000 bytes, the result becomes 50,000,000 ÷ 40 = 1,250,000 BPI.
Domain Name System and the address lookup process
Question 3 (b): What is the Domain Name System (DNS)? Describe the steps involved in translating a website address to the corresponding IP address. (8)
Answer: the Domain Name System (DNS) is the distributed, hierarchical naming system of the internet that converts human-readable domain names, such as www.ignou.ac.in, into the numeric IP addresses that computers use to find each other.
Why DNS is needed
Every host on the internet is reached through an IP address, for example 203.0.113.25 in IPv4 form. People cannot remember thousands of such numbers, and a website may change its server and IP address over time. DNS lets users type a stable name while the system quietly supplies the current address.
How the DNS hierarchy is organised
The name space is an inverted tree. At the top are the root servers. Below them sit top-level domains (TLDs) such as .com, .org and country codes like .in. Below those come second-level and lower domains, so in www.ignou.ac.in the parts are read from right to left: .in, then ac.in, then ignou.ac.in, and finally the host www.
Main components
A DNS resolver (usually run by your ISP or a public DNS service) does the searching for the client. Name servers store records for their zones, and an authoritative name server holds the final answer for a domain. The most common record is the A record, which maps a name to an IPv4 address (an AAAA record does the same for IPv6).
Steps in translating a website address to an IP address
- The user types www.ignou.ac.in in the browser. The browser first checks its own cache to see whether it resolved this name recently.
- If not found, the request passes to the operating system, which checks its DNS cache and the local hosts file.
- If the name is still unresolved, the computer sends a recursive query to its configured DNS resolver, normally over UDP port 53.
- The resolver checks its own cache. If the answer is not cached, it sends an iterative query to a root name server, which replies with the address of the name servers for the .in TLD.
- The resolver asks the .in TLD server, which refers it to the name servers responsible for ac.in, and they in turn refer it to the authoritative name servers for ignou.ac.in.
- The authoritative name server returns the A record, that is, the IP address for www.ignou.ac.in, along with a time-to-live (TTL) value.
- The resolver stores the answer in its cache for the TTL period and sends the IP address back to the client computer, which also caches it.
- The browser now opens a connection to that IP address using TCP/IP and requests the web page over HTTP or HTTPS.
Recursive versus iterative queries. The client makes one recursive query and expects a final answer from the resolver. The resolver, in contrast, makes iterative queries, following referrals from root to TLD to authoritative server. Caching at every level means most lookups finish in milliseconds without going back to the root.
Conclusion. DNS works like the phone directory of the internet. Its hierarchy spreads the load across millions of servers, caching keeps it fast, and the step-by-step referral process lets any name in the world be turned into an IP address.

5. Question Paper Pattern and Marks Split
The June 2026 BCS 111 paper carries 100 marks in 3 hours: Question 1 is compulsory for 40 marks, and you pick any three of Questions 2 to 5 at 20 marks each.
Question 1 is the heavy one, with seven parts ranging from 4 to 10 marks, including five short notes worth 2 marks each. Questions 2 to 5 mix one diagram or numerical with shorter theory parts, so choosing the right three matters.
| Question | Parts and focus | Marks | Choice |
|---|---|---|---|
| Question 1 | 7 parts: (a) to (g), with (a) holding 5 short notes | 10 + 5 + 6 + 5 + 6 + 4 + 4 = 40 | Compulsory |
| Question 2 | 4 parts: twisted pair, two program fragments, PC configuration, OS execution steps | 6 + 5 + 5 + 4 = 20 | Any three of Q2 to Q5 |
| Question 3 | 3 parts: courier data speed, DNS, 20-bit machine instruction | 5 + 8 + 7 = 20 | Any three of Q2 to Q5 |
| Question 4 | 3 parts: software project management, ROM and PROM, while loop | 6 + 7 + 7 = 20 | Any three of Q2 to Q5 |
| Question 5 | 3 parts: OOP concepts, MS Word tables, ASCII and Unicode | 6 + 6 + 8 = 20 | Any three of Q2 to Q5 |
Across the paper that adds up to 20 parts, of which you answer Question 1 plus three full questions for 100 marks. To see how this layout compares with older sessions, open the BCS 111 question paper sets on our IGNOU Previous Year Question Paper hub.

7. How Our Answers Are Written and Checked
Every BCS 111 answer is written against the matching IGNOU unit, sized to the marks printed on the paper, and checked by a second reviewer before release.
A 2-mark short note on a repeater gets a crisp definition and one working line, while the 8-mark ASCII and Unicode answer gets characteristics, features and the Consortium goals in separate parts. Length follows marks, which is how IGNOU examiners award them.
Numericals get extra care. Each one shows the given data, unit conversions, formula, working and a reverse check, as in the tape answer above. Where IGNOU could accept two readings, such as 1 MB as 1,048,576 or 1,000,000 bytes, both are shown with the assumption stated.
Diagram questions, such as the linker, the twisted pair cable and the analogue and digital signal graph, come with labelled figures in the file. Program fragments are written in simple pseudocode that any BCA examiner can follow, with a line-by-line explanation beneath.
8. Practical File Index and Question Map
BCS 111 has a practical partner, BCSL-013 Computer Basics and PC Software Lab (2 credits), and several June 2026 theory questions sit right on top of that lab work.
The lab tasks below come from the official BCSL-013 assignment for the July 2025 and January 2026 sessions. In that assignment the Windows and Linux lab record carries 40 of 100 marks and viva voce another 20, so practising both sides together pays off.

9. Programmes That Include BCS 111
BCS 111 Computer Basics and PC Software is a Semester I course in IGNOU BCA_NEW and BCA_NEWOL, while old BCA students take the same paper under the code BCS-011.
- BCA_NEW: the distance mode Bachelor of Computer Applications (ODL), where BCS-111 sits in Semester I with BEVAE-181, BEGLA-136, BCSL-013 and BCS-012 for a total of 20 credits.
- BCA_NEWOL: the online BCA, which follows the same Semester I structure and credit load, so BCS-111 again carries 4 credits alongside the 2-credit BCSL-013 lab.
- Old BCA (revised): students still on the earlier scheme study BCS-011 as a 3-credit course. IGNOU internal credit transfer maps BCS-011 to BCS-111 for students moving into BCA_NEW, which is why both codes share one term-end paper.

11. BCS 111 Computer Basics and PC Software FAQs
These are the questions BCA students ask us most about the BCS 111 June 2026 solved paper, answered in short.
What is BCS 111 Computer Basics and PC Software in IGNOU BCA?
BCS 111 Computer Basics and PC Software is a 4-credit Semester I course in the IGNOU BCA_NEW and BCA_NEWOL programmes, offered by the School of Computer and Information Sciences. Its 3 blocks cover computer hardware, computer software and internet technologies across 12 units. The June 2026 paper was printed jointly for BCS-011 and BCS-111, so old and new BCA students answered the same questions.
How many questions are in the June 2026 question paper?
The BCS 111 June 2026 paper has 5 main questions split into 20 parts. Question 1 is compulsory, carries 40 marks and has 7 parts, including five short notes. Questions 2 to 5 carry 20 marks each and you attempt any three of them. Our full file answers all 20 parts, while this page shows only 2 of them with complete answers.
How do I get the full solved file on WhatsApp?
Send the message BCS 111 June 2026 on WhatsApp to 9899436384. Our team replies with the price, and once you confirm, you receive the complete PDF. It contains answers to all 20 parts of the paper, which means the 2 samples on this page plus the 18 answers that are not shown here, written in the length IGNOU examiners expect.
Which BCS 111 topics repeat most often in IGNOU exams?
IP addressing and DNS, plus operating system services, appeared in all 5 official BCS-011/BCS-111 papers we checked, from June 2023 to December 2025. Utility software, memory types, number systems, loops, storage sums and security each appeared in 4 of them. We could not find the December 2024 paper on IGNOU sites, so every count on this page is out of 5 sessions, not 6.
Is the BCS 111 paper the same as BCS-011 for old BCA students?
Yes. For June 2026, IGNOU printed one paper carrying both codes, BCS-011 and BCS-111, and labelled it BCA Old/New. Old BCA students study BCS-011 as a 3-credit course while BCA_NEW students study BCS-111 as a 4-credit course, but the term-end questions were identical. Our solved file therefore works for both groups without any changes or extra material.
Does the solved paper include numerical answers?
Yes. Three June 2026 questions need working: the magnetic tape recording density in Q1(e), the courier data speed for a 1 TB hard disk in Q3(a), and the 20-bit machine instruction for 49 × 207 in Q3(c). The tape numerical is solved in full on this page. The other two are worked step by step only in the full file.
Is there a practical course linked to BCS 111?
Yes. BCS 111 is the theory course with a 3-hour term-end exam, and its practical partner is BCSL-013 Computer Basics and PC Software Lab, worth 2 credits. In the 2025-26 BCSL-013 assignment, the Windows and Linux lab record carries 40 of 100 marks and viva voce 20. The MS Word table question, Q5(b), overlaps directly with that lab work.
Who writes and checks the BCS 111 answers?
Every BCS 111 answer is drafted by our computer applications team under author Prateek Talwar and then reviewed by Sheetal Kirola before release. The reviewer checks each answer against the relevant IGNOU unit, verifies every calculation, and confirms that the length matches the marks printed on the paper. Answers that fail any of these checks go back for a rewrite.
12. Who Wrote and Checked the BCS 111 Answers
The BCS 111 answers were drafted by Prateek Talwar and the Unnati Educations computer applications team, and reviewed by Sheetal Kirola.
Prateek Talwar prepares IGNOU computer-science solved papers from the course blocks and the official term-end paper. Sheetal Kirola, Academic Head (M.Ed.), checks every answer against its IGNOU unit, verifies each calculation and confirms that answer length matches the marks printed on the paper.
