Digital Logic Fundamentals: Number Systems, BCD, and K-Maps
Number System Basics and Computer Use
(a) What is a Number System?
A number system is a way of representing numbers using a set of symbols and a base (radix). Examples include:
- Decimal (base 10)
- Binary (base 2)
- Octal (base 8)
- Hexadecimal (base 16)
b) Why Digital Computers Use Binary Number System?
Digital computers use binary because:
- Electronic circuits have two states: ON (1) and OFF (0).
- Binary is reliable and easy to implement.
- It results in less error in data processing.
(c) Convert (1001.0010)₂ to Decimal
Integer

Octopuses have an amazing body design, enabling them to defend themselves in a variety of ways. Their primary defense strategy relies on mobility and evasion.
Evasion and Jet Propulsion
The most common defense is flight, utilizing jet propulsion to quickly move through the water. Their flexible body, lacking bones, allows them to escape into small cracks, rocks, crevices, and even discarded items like bottles and cans found on the seafloor.
The Disorienting Ink Cloud
Octopuses are well known for their

Cloud computing is a transformative technology that enables users to access computing resources over the internet rather than on physical devices or local servers. This detailed note covers key concepts, types, benefits, and use cases of cloud computing.
What is Cloud Computing?
Cloud computing refers to the delivery of various services over the internet, including storage, processing, networking, databases, software, and more. It allows businesses and individuals to use computing resources on-demand

Le Corbusier’s Modern Urbanism: Open Block Construction
Le Corbusier’s modern urbanism proposed raising building blocks on pilotis (pillars), seeking continuity by converting previously impassable areas into zones where people could move freely, complemented by numerous gardens. This was achieved by vacating the ground floor, leaving only the supporting pillars.
This new proposal created distinct spaces, separating road traffic from pedestrian traffic. This type of structure is known as open block

The Value of Independence and Saving
- In other European countries, children learn to manage without the help of their parents at a younger age so that they can learn to deal with daily problems independently.
- When I started making my living as a journalist, my parents advised me to save money for a rainy day, but I preferred not to listen to them, so I am now in the red.
Dealing with Conflict and Uncertainty
No matter how much you threaten me, you won’t get anything.

Defining and Achieving Wellness
Wellness is the process by which health is achieved, involving choices that we make to improve or maintain health, or more broadly, improve our existence. Wellness, like health, exists across various dimensions.
Dr. Bill Hettler’s Six Dimensions of Wellness
- Intellectual:
- Expanding knowledge, engaging in creative and stimulating activities.
- Physical:
- Self-care and health-enriching behaviors.
- Spiritual:
- Appreciation for life and natural forces in the universe.
- Emotional:
- Awareness
Prospectus, Share Types and Share Capital Regulations
Prospectus
A prospectus is a legal document issued by a public company inviting public subscriptions for shares or debentures, containing detailed disclosures on company objectives, financials, risks, management, and capital structure per SEBI (ICDR) Regulations and Companies Act, Section 26 [from previous]. It ensures investor protection through mandatory information such as material contracts, litigation, and promoter details; shelf/deemed prospectuses apply for follow-on offers [from previous]
Digital Number Systems: Binary, Hexadecimal, and BCD
Understanding Number Systems
Number systems are fundamental to computing and digital electronics. They are essentially methods for representing numbers using a specific set of symbols (digits). The key concept differentiating them is the base or radix, which is the total number of unique digits available in that system.
Common Number Systems Breakdown
1. Decimal (Base-10)
This is the number system we use every day.
- Base (Radix): 10
- Digits Used: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
- Concept: Each digit’s position
Cinematic Contrast: Loneliness and the Male Gaze in Her and Lambs
Representing Isolation: Her vs. The Silence of the Lambs
Spike Jonze’s Her (2013) and Jonathan Demme’s The Silence of the Lambs (1991) both examine characters who experience deep loneliness, but they show this isolation using very different visual strategies. Her uses warm colors, soft lighting, and close-up shots to reveal Theodore’s emotional isolation and his sometimes idealized or unrealistic view of the women around him. In contrast, The Silence of the Lambs relies on point-of-view shots,

The Iterative Design Process
The iterative design process is one of the most traditional processes for the design of any engineering component or system. It is used widely throughout many industries. The process is not very efficient! With the advent of more streamlined digital workflows, we aim to cut out excess iterations from our process. The majority of your projects will likely follow this process.
