SRT (Shortest Remaining Time)
The next process to enter the processor is the one with the shortest remaining runtime. When a new process arrives with a shorter runtime than the currently running process, the latter is evicted from the CPU, and the shorter process begins execution. It’s a preemptive variant of the Shortest Job Next (SJN) algorithm.
Features:
- Variation of SJN.
- Preemptive policy.
- Very efficient.
- Possibility to assign priorities, where the system adjusts runtime based on priority (multiplying
Effective Software Testing for Quality Assurance
Software Testing
Software testing is the process of evaluating a program to identify defects before it reaches end-users.
Test Objectives
- Uncover software flaws.
- A test is successful if a defect is found.
- A test fails if defects are present but not detected.
Test Types
- Verification Test: Checks if the software meets design specifications.
- Validation Test: Checks if the software fulfills analysis qualifications.
- Operational Test: Ensures the software operates correctly.
Test Characteristics
- Observability: The
Network Classification, Components, and Protocols
Network Classification
Definition
A network is a system of interconnected devices that can communicate and share resources. Its objective is to facilitate information and resource sharing, making data and programs accessible to any authorized user on the network, regardless of their physical location.
Network Extension
- LAN (Local Area Network): Typically spans a single building or smaller area, commonly used in offices and facilities.
- MAN (Metropolitan Area Network): Covers a larger geographic area,
Mastering Core OOP Concepts: Type Casting to Inheritance
What is type casting? Explain with suitable example.? 5 marks
Type casting refers to the process of converting a variable from one data type to another. It is commonly used in programming when the operations or functions involved require data of a specific type. Type casting can be done explicitly (manual casting) or implicitly (automatic conversion).
Types of Type Casting:
1.)Implicit Type Casting (Type Promotion): The compiler automatically converts a smaller data type to a larger data type to prevent
