Answer available — download the full PDF for complete details.

Q1. Answer the following questions:

(a)) What is computer system? Explain with the help of Block Diagram. (300 words)
(b)) What are output devices? Briefly explain the various output devices. (300 words)
(c)) What is secondary memory? Explain how is it different from primary memory. (300 words)

Key Points:

A computer system consists of Input, CPU, Memory, and Output units, transforming data into information.
The CPU (ALU, CU, Registers) is the system's 'brain,' executing instructions and controlling operations.
Output devices (monitors, printers, speakers) present processed data in human-readable formats.
Monitors provide visual display; printers (inkjet, laser) produce hard copies on paper.

Answer:

Q2. Answer the following questions:

(a)) What is software? What is application software? How is it different from utility software? (300 words)
(b)) What is a Flowchart? Explain different symbols used in Flowcharts. Draw a flowchart for finding the largest among three numbers. (450 words)
(c)) Write a C program to find the area of a circle. (300 words)

Key Points:

Software consists of instructions operating hardware; categorized into system and application types.
Application software performs specific user tasks (e.g., word processor, browser).
Utility software manages and optimizes computer resources (e.g., antivirus, disk defragmenter).
Flowcharts visually represent algorithms using standardized symbols like Terminal, Process, Decision.

Answer: The field of computer science encompasses fundamental concepts like software, programming logic, and basic programming. This answer delves into these core areas, as typically covered in the CIT-001 'Fundamentals of Computer Systems' course. It explains what software is, differentiates between application and utility software, introduces flowcharts as a problem-solving tool with their symbols, and provides a practical C programming example for calculating the area of a circle. Understanding thes...

Q3. Answer the following questions:

(a)) What is computer network? Briefly explain star and ring network topologies. (300 words)
(b)) Explain asynchronous and synchronous mode of data transmission with the help of examples. (300 words)
(c)) Explain OSI reference model. (300 words)

Key Points:

A computer network enables interconnected devices to share data and resources.
Star topology uses a central hub; easy management but vulnerable to central point failure.
Ring topology connects devices in a loop; data flows unidirectionally, vulnerable to single node failure.
Asynchronous transmission uses start/stop bits for character-by-character data (e.g., keyboard input).

Answer: Computer networks form the backbone of modern digital communication, enabling devices to share resources and information globally. Understanding various network topologies, data transmission methods, and architectural models like OSI is crucial for designing and managing efficient and reliable communication systems. Each component plays a vital role in ensuring seamless data exchange, from the physical connections to the application-level interactions. Network topologies dictate the physical an...

Q4. Answer the following questions:

(a)) What is social networking? Explain its advantages. (300 words)
(b)) What is need of information security? List different security threats in computer network. (300 words)
(c)) What is computer virus? What are different types of viruses? Explain how a computer system can be protected from computer virus. (300 words)

Key Points:

Social Networking: Online platforms for connecting, sharing content, and interacting within a defined system.
Social Networking Advantages: Enhanced communication, information sharing, community building, professional networking, and marketing.
Information Security Need: Protects Confidentiality, Integrity, and Availability (CIA) of data to prevent losses and ensure privacy.
Computer Network Threats: Include Malware (viruses, worms), Phishing, DoS/DDoS, Unauthorized Access, Data Theft, Spyware, and Ransomware.

Answer: Social networking refers to the use of internet-based platforms and applications that allow individuals to create public or semi-public profiles within a bounded system, articulate a list of other users with whom they share a connection, and view and traverse their list of connections and those made by others within the system. These platforms facilitate communication, content sharing, and interaction among users who share interests, activities, or backgrounds. Examples include Facebook, Twitter...
