The document discusses the goals and methods of computer protection. It aims to control access to resources and prevent their unauthorized use. Hardware protection differentiates between user and monitor modes. The CPU protects modes through a mode bit, and switches to monitor for interrupts. Memory protection prevents processes from accessing memory not allocated to them. I/O protection makes I/O instructions privileged to monitor mode only. The goals are to share resources safely according to policies and minimize damage from misbehaving programs.

Multithreading
The document discusses multithreading and how it can be used to exploit thread-level parallelism (TLP) in processors designed for instruction-level parallelism (ILP). There are two main approaches for multithreading - fine-grained and coarse-grained. Fine-grained switches threads every instruction while coarse-grained switches on long stalls. Simultaneous multithreading (SMT) allows a processor to issue instructions from multiple threads in the same cycle by treating instructions from different threads as independent. This converts TLP into additional ILP to better utilize the resources of superscalar and multicore processors.
Operating system structures
This chapter discusses operating system structures and concepts. It describes the services operating systems provide to users and processes, such as user interfaces, program execution, I/O operations, file manipulation, communications, and error detection. It also discusses how operating systems ensure efficient resource sharing through resource allocation, accounting, protection and security. The chapter covers system calls, which are the programming interface to OS services, and how system calls are typically implemented and accessed through APIs rather than direct calls.
Introduction to Distributed System
The document provides an introduction to distributed systems, defining them as a collection of independent computers that communicate over a network to act as a single coherent system. It discusses the motivation for and characteristics of distributed systems, including concurrency, lack of a global clock, and independence of failures. Architectural categories of distributed systems include tightly coupled and loosely coupled, with examples given of different types of distributed systems such as database management systems, ATM networks, and the internet.
Protection and security
1. Protection and security are mechanisms used in operating systems to control access to resources and safeguard them from threats. Protection focuses on internal threats while security addresses external threats.
2. Protection involves setting and changing access permissions for resources and checking access for users. Security involves authenticating users, adding/removing them, and using anti-malware software to protect from external threats.
3. A security model like the access matrix model defines the set of subjects, objects, and access rules to represent an organization's security policy for controlling access between users and resources.

Kernel (OS)
This Presentation descrbes what is kernel, how it works, types of kernel, advantages and disadvantages of kernel and responsibilities of kernel.
Memory allocation (4)
Memory is encoded, stored, and retrieved through processes. Encoding allows external information to reach our senses. Memory allocation involves setting aside space, such as allocating hard drive space for an application. It places blocks of information in memory systems. To allocate memory, the memory management system tracks available memory and allocates only what is needed, keeping the rest available. If insufficient memory exists, blocks may be swapped. Static and dynamic allocation methods exist, with dynamic using nonpreemptive and preemptive allocation. Nonpreemptive allocation searches memory for available space for a transferring block. Preemptive allocation more efficiently uses memory through compaction. Different memory types store executable code, variables, and dynamically sized structures, with heap memory

Distributed file systems must also address being stateful or stateless to maintain information about file access and operations.
Chapter2 Encapsulation (Java)
Encapsulation is a technique that makes fields in a class private and provides access to them via public methods. This prevents code outside the class from randomly accessing fields. Encapsulation combines data and behaviors in a class, and allows only behaviors to access and modify the data, controlling its values. It hides how an object works internally, making only its behaviors visible. Encapsulation draws boundaries around data and methods, allowing developers to use code without knowing how it works. It makes code more maintainable, flexible, and extensible by allowing updates without changing input/output formats.

Deadlock Prevention
This document discusses deadlock prevention by invalidating one of the four conditions necessary for deadlock: mutual exclusion, hold and wait, no preemption, and circular wait. It describes strategies to prevent each condition, such as not requiring mutual exclusion for sharable resources, requesting all resources before execution or only when a process has none to prevent hold and wait, allowing preemption of held resources to prevent no preemption, and imposing a total ordering of resource requests to prevent circular wait. These techniques aim to ensure deadlock is excluded from the beginning.
Semophores and it's types
This document discusses semaphores and their use in solving critical section problems. It defines semaphores, describes their wait and signal methods, and types including counting and binary semaphores. It then explains how semaphores can be used to solve classical synchronization problems like the bounded buffer, readers-writers, and dining philosophers problems. Examples of semaphore implementations are provided for each problem.
Process synchronization
This document discusses various techniques for process synchronization. It begins by defining process synchronization as coordinating access to shared resources between processes to maintain data consistency. It then discusses critical sections, where shared data is accessed, and solutions like Peterson's algorithm and semaphores to ensure only one process accesses the critical section at a time. Semaphores use wait and signal operations on a shared integer variable to synchronize processes. The document covers binary and counting semaphores and provides an example of their use.
System calls
This presentation discusses system calls and provides an overview of their key aspects:
System calls provide an interface between processes and the operating system. They allow programs to request services from the OS like reading/writing files. There are different methods of passing parameters to the OS, such as via registers, parameter blocks, or pushing to the stack. System calls fall into categories including process control, file management, device management, information maintenance, and communication. An example is given of how system calls would be used in a program to copy data between two files.
Os Threads
This document discusses threads and threading models. It defines a thread as the basic unit of CPU utilization consisting of a program counter, stack, and registers. Threads allow for simultaneous execution of tasks within the same process by switching between threads rapidly. There are three main threading models: many-to-one maps many user threads to one kernel thread; one-to-one maps each user thread to its own kernel thread; many-to-many maps user threads to kernel threads in a variable manner. Popular thread libraries include POSIX pthreads and Win32 threads.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in

Goals of protection
- 3. What is protection ? Hardware protection? Goals of protection?
- 4. Protection is the subset of computer security that deals with controlling , accessing and protecting the computer resources which is provided by operating system
- 5. Dual mode protection C PU protection Memory protection Input/output protection
- 6. Dual mode protection •Sharing system resources requires operating system to ensure that an incorrect program cannot cause other programs to execute incorrectly. Provide hardware support to differentiate betweenat least two modes of operations.
- 7. 1. User mode execution done on behalf of a user. 2.Monitor mode execution done on behalf of operating system.
- 8. Interrupt/fault monitor user Set user mode
- 9. Mode bit added to computer hardware to indicate the current mode: monitor (0) or user (1). When an interrupt or fault occurs hardware switches to monitor mode monitor Privileged instructions can be issued only in monitor mode.
- 10. . Timer - interrupts computer after specified period to ensure operating system maintains control. Timer commonly used to implement time sharing. g Timer also used to compute the current time.
- 11. Memory protection main purpose of memory protection is to prevent a process that has not been allocated to it
- 12. I/O Protection All I/O instructions are privileged instructions. Must ensure that a user program could never gain control of the computer in monitor mode (i.e., a user program that, as part of its execution, stores a new address in the interrupt vector ).
- 13. To prevent malicious misuse of the system by users or programs To ensure that each shared resource is used only in accordance with system policies, which may be set either by system designers or by system administrators. To ensure that errant programs cause the minimal amount of damage possible.
