Threads, Multithreading, Types of thread, Multithreading models in Operating Systems (OS) Thread in Operating system. Thread is a sequence of instructions within a process. A thread behaves like a process within a process but it does not have its own PCB. A thread is the basic unit of CPU utilization. It is also called a lightweight process.
Processes have independent data and code segments. Dependent or independent. Threads are dependent on process. Individual processes are independent. Memory Sharing. A thread may share some memory with its peer threads. Processes don’t share memory. Resource Consumption. Threads are Light weight so need less resources..

Ethical Decision-Making Models MCQs; Threads, Multithreading, Types Models in Operating Systems (OS) Consistency models and protocols MCQs in DBMS
MCQs on Relational Model in DBMS. Who is credited with the creation of the relational database model? A. Edgar F. Codd. B. Charles Bachman. C. Larry Ellison. D. James Gosling. Answer: A. Edgar F. Codd. In the relational model, data is organized into: A. Trees.
State of the process in PCB. PCB maintains the record of the state of each process. A process can be in new, waiting, ready, running and can be in the terminated state. Two state, 5 state, 7 state and some other process models are used to represents the flow of the process from one state to another state.
What are the advantages of the Iterative model? We can start with a little of a requirement specification. We can detect the defects, faults, and risks at an early stage. Supports user feedback. Less time is utilized for documentation. More time is utilized for software development.
Answer: A. Multicore Architecture. What is the benefit of having multiple cores in a single processor chip for handling parallel tasks? A. Enhanced Performance and Efficiency. B. Increased Network Speed. C. Improved Graphics Rendering. D. Higher Storage Capacity. Answer: A. Enhanced Performance and Efficiency.
These two states are. State 1: Process is Running on CPU. State 2: Process is Not Running on CPU. New: First of all when a new process is created, then it is in Not Running State. Suppose a new process P2 is created then P2 is in NOT Running State. CPU: When the CPU becomes free, Dispatcher allows the P2 to use the CPU.
This process model contains five states that are involved in the life cycle of a process. New. Ready. Running. Blocked / Waiting. Exit. New: When a new process is created, then this new process is in the new state. A process in the new state tries its best to load into the RAM.
What does the term “instruction format” refer to in an ISA? a) The set of instructions available in the architecture. b) The number of addressing modes. c) The structure and layout of an instruction. d) The sequence of instruction execution. Answer: c) The structure and layout of an instruction. 20.
