OSmodule1_ppt.pptx
The document provides an overview of operating systems, including definitions, functions, and evolution. Some key points:
- An operating system acts as an intermediary between user applications and computer hardware, managing resources and allowing for multitasking.
- The main functions of an OS include resource management, storage management, process management, memory management, file management, device management, and security/protection.
- Early operating systems evolved from serial processing to batch processing to multiprogramming and time-sharing to better utilize hardware and reduce turnaround time for users.
- Modern OS must balance individual usability, resource utilization, and response time depending on the system type (personal computer, mainframe, network, etc
Operating System.ppt
The document discusses operating systems and their functions. An operating system (OS) is a program that manages computer hardware resources and provides common services for computer programs. It acts as an interface between users and the computer hardware. The key functions of an OS include managing CPU time and memory, allowing for program creation and execution, providing access to I/O devices and files, and resolving conflicts over resource contention and access. There are three classical views of an OS: as a resource manager that allocates hardware resources, as a control program that oversees execution and prevents errors, and as a command executer that provides an interface for users to run programs and utilities.
Information Technology
This document provides an overview of information technology (IT) including its key components and functions. IT deals with using computers and software to store, process, and retrieve information. The backbone of IT is computers, which have hardware and software. Computer hardware includes input, processing, and output units. Computer software includes application software, system software, and utility software. Databases help manage data through database management systems. Operating systems act as an interface between users and hardware. Networks allow computers to connect and share resources through local, metropolitan, and wide area networks. Enterprise resource planning systems integrate organizational data and processes into a single system.
Real time operating system
Real-time operating systems are designed to handle tasks with strict timing constraints. They manage computer hardware resources and provide services to real-time computer programs. Real-time tasks must be completed by their deadlines to maintain the correct functionality of systems like digital controls that periodically sense status and actuate systems. Real-time operating systems prioritize predictability and ensuring tasks meet timing deadlines over average performance metrics. They schedule processors and allocate memory in a way that guarantees tasks will finish processing by their required times.
The Operating System
The document discusses the main functions of operating systems, which include resource management, establishing a user interface, and executing and providing services for applications. Specifically, it notes that the operating system manages processes and resource allocation, ensures instructions are handled in queue, and allocates memory and resources for each task. It also states that the resource manager allocates memory and processor resources for scheduled processes to complete tasks.

It describes how operating systems act as an intermediary between the user and computer hardware by managing resources, executing programs, and handling input/output. The key functions of operating systems are process management, memory management, file management, input/output management, and secondary storage management. Operating systems also provide services like program execution, input/output operations, file system manipulation, communications, error detection, resource allocation, accounting, and protection.

How to Make a Field Mandatory in Odoo 17
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.
