The Shreya Singhal vs. Union of India (2015) case is a landmark judgment where the Supreme Court of India struck down Section 66A of the Information Technology Act, 2000, declaring it unconstitutional. Here's the key details:
- Background: Shreya Singhal, a law student, challenged Section 66A after two girls were arrested in 2012 for Facebook posts criticizing a Mumbai shutdown following a politician's death. The provision criminalized sending "grossly offensive," "menacing," or messages causing
1. Types of OS.
Operating systems can be classified based on their structure, usage, and capability:
Batch Operating System:
Jobs with similar needs are grouped (batched) and run together.
No direct interaction between the user and the computer during job execution.
Goal: Maximize CPU utilization.
Example: Used in environments that process large, repetitive tasks, like payroll systems.
Time-Sharing (Multitasking) OS:
The CPU switches rapidly between multiple jobs (processes) to give each user the impression...
1. CPU Scheduling and Their Time
CPU Scheduling is the process of deciding which of the processes in the ready queue should be allocated to the CPU for execution. It's necessary when a process switches from running to waiting, terminates, or when a new process is created.
Scheduling Criteria (Times):
The performance of a CPU scheduler is measured using several metrics, often expressed in terms of time:
CPU Utilization: The fraction of time the CPU is busy executing processes. (Goal: Maximize)
Throughput:...
Why are randomized experiments so desirable?
Randomization breaks the link between treatment assignment and confounders, making treated and untreated groups exchangeable. This guarantees unbiased estimates of causal effects (on average) because any differences in outcomes can be attributed to the treatment rather than selection.
Why might we not be able to run a randomized experiment?
They may be unethical (e.g., denying beneficial treatments), infeasible (cost, logistics), illegal, or...
Unit 1: Introduction NT & Christology: parable- short story that uses everyday images to communicate religious messages, both reveal and conceal, different types of parables (The Surprise of God’s Kingdom, God’s upside down Kingdom, God’s Kingdom requires a decision) King Herod- ambitious, brutal, and successful, rebuilt the Temple in Jerusalem, allowed local rulers to oversee small areas as long as they pledged their allegiance to Rome, maintained strict control Pontius Pilate- Roman...
This section covers the core combinational circuits that form the backbone of digital systems. Mastery of their design, truth tables, and applications is essential for Unit III.
1. ➕ Arithmetic Circuits: Full Adder and Full Subtractor
These circuits perform the fundamental binary arithmetic operations.
A. Full Adder (FA)
A Full Adder is a combinational logic circuit that performs the addition of three single-bit binary numbers: two operands (A and B) and a carry-in (C_{in}) from a previous stage.
🔄 Flip-Flop Conversion: Steps and Examples
The goal of flip-flop conversion is to use an available flip-flop (the basic component you have) along with a combinational logic circuit to make the overall system behave like a required flip-flop (the target).
General Steps for Conversion
* Identify Available and Required FFs:
* Required FF (Target): The one you want to emulate (e.g., T-FF). Its inputs are the external inputs for the final circuit.
* Available FF (Source): The one you are using
Week 1 & 2
1. Understand the concept of e-business and explain how it differs from e-commerce in terms of scope, activities, and strategic focus.
: e-Commerce (Electronic Commerce) refers to digitally enabled commercial transactions across organizations/individuals, encompassing the online buying/selling of goods and services.
e-Business refers to the digital enablement of business processes and transactions not only across firms but also within a firm through Information Systems.
Scope: e-
...| Secured Loans: loans backed by an asset | Common law and statutory law deal with what to do in case of default | Liens: a claim against specific property to satisfy debt | Mechanics liens: a security interest given to someone who provides work or improvements to a specific parcel of property | Judgement liens: a legal claim placed on a debtor’s property after a court issues a monetary judgment against them. It ensures the creditor gets paid if the debtor sells or refinances their property. |
