 01 explain 1-bit image

 A 1-bit image is a type of digital image that uses only one bit per pixel to represent its color or grayscale value. Since a single bit can only have two possible values (0 or 1), a 1-bit image is essentially a binary image, where each pixel is either black or white.

### Key Characteristics:
- **Bit Depth**: The bit depth of the image is 1, meaning each pixel is represented by a single bit.
- **Color Representation**: The two possible values for each pixel (0 and 1) typically correspond to two colors:
  0 = Black
  1 = White
- **File Size**: 1-bit images have very small file sizes compared to higher bit-depth images because each pixel requires only one bit of storage.
- **Applications**: Commonly used in simple graphics, icons, logos, and in situations where color is not needed, or where it is important to minimize file size.

### Example:
Imagine a small 1-bit image of a checkerboard pattern. In this image:
- The black squares would be represented by `0`s.
- The white squares would be represented by `1`s.

The simplicity of 1-bit images makes them useful in contexts where minimal data usage is critical, such as in early computer graphics and some types of printing processes.

It can store, retrieve, and process information and it is capable of executing a wide range of operations based on instructions provided to it. Computers come in various forms, including personal computers, laptops, servers, and embedded systems. 1.       Central Processing Unit (CPU): Often referred to as the brain of the computer, the CPU performs calculations and executes instructions.   2.       Memory (RAM): Random Access Memory is used to temporarily store data that the CPU needs to access quickly. It is volatile memory, meaning it loses its contents when the power is turned off.   3.       Storage: This includes devices l...

Unit 2: Foundations of Ownership, Security Related Concepts in Blockchain

  Unit 2: Foundations of Ownership, Security Related Concepts in Blockchain Foundations of Ownership In traditional systems, ownership is often documented and verified by centralized authorities (e.g., land registries, banks). In blockchain, ownership is established and proven through cryptographic methods, primarily using public-key cryptography . Public and Private Keys: Each user on a blockchain network has a unique pair of cryptographic keys: a public key and a private key. The public key acts as an address, similar to an account number, visible to everyone. It's used to receive assets or data. The private key is a secret code that grants control over the assets associated with the public key. Only the person possessing the private key can authorize transactions from that address. Digital Signatures: To prove ownership or authorize a transaction, a user digitally "signs" a message or transa...

Unit-1 Foundations of Software Systems and Blockchain

  Unit 1: Foundations of Software Systems and Blockchain 1. Layers of a Software System Software systems are typically organized into layers to separate responsibilities, improve maintainability, and allow independent scaling. Common layers include: Presentation Layer: Handles user interface (UI) and user interaction (e.g., web pages, mobile app screens). Application/Business Logic Layer: Contains the core business rules and orchestrates data flow, processing user requests (the "brains" of the application). Data Access Layer (DAL): Provides an interface for the application to interact with data storage, abstracting database complexities. Data Layer: The actual persistent storage for data (e.g., databases, file systems). This layered approach promotes modularity and makes systems easier to develop, test, and update. 2. Integrity Integrity in software systems ensures that data is accurate, consistent, and trustworth...
