Amr Chap 08 Operating Systems & Utility Programssharing notes123
油
System software consists of operating systems and utility programs. Operating systems control computer hardware resources and are divided into stand-alone, server, and embedded categories. The boot process starts when a computer powers on, involving the BIOS performing POST to check components, then the operating system loads files and the desktop. Utility programs allow maintenance tasks like file management, uninstalling programs, and backing up files.
The operating system coordinates and monitors all activities of the computer hardware resources, allows running multiple programs simultaneously, and provides file management and security. It stores memory, monitors system performance, and provides user interfaces. Popular operating systems include Macintosh, Unix, and Windows. The operating system boots the system, allows multitasking of programs, connects the computer to the internet, monitors performances, and enables networking and resource sharing between devices while maintaining security.
This document provides an introduction and overview of operating systems. It defines an operating system as a program that manages computer hardware resources and provides common services for computer programs. It describes the four main components of a computer system: hardware, operating system, application programs, and users. It also outlines some of the key services an operating system provides, such as program execution, I/O operations, file management, and resource allocation. Finally, it discusses the structure and evolution of modern operating systems from early batch and time-sharing systems to current multiprogramming systems.
The document discusses the boot process and evolution of operating systems. It explains that the boot process has two steps: first the POST checks hardware components and then the bootstrap loader loads the OS from the hard drive to RAM. It also summarizes the evolution of operating systems from batch systems of the 1950s, to time-sharing systems with multi-programming, to personal systems like DOS for single-user PCs, to parallel systems using multiple CPUs, distributed systems across networks, and real-time systems which perform tasks within time constraints.
The document discusses the key components and functions of an operating system:
1. It manages computer hardware resources and allows for the execution of user programs and applications.
2. It provides services like process management, memory management, file management, I/O management, and protection to programs and users.
3. Operating systems provide an interface between the user and computer system through functions like command interpretation.
An operating system acts as an intermediary between a computer user and the computer hardware. It makes the computer system convenient to use by allowing users to execute programs and efficiently allocating hardware resources like CPU time and memory among applications. The main components of a computer system are the hardware, operating system, application programs, and users. Common operating systems include Mac OS, Linux, UNIX, and Windows.
A virtual machine treats hardware and the operating system kernel as if they were physical hardware. It provides an interface identical to the underlying physical hardware. Resources of the physical computer are shared to create the illusion of multiple virtual machines, each with their own processor and memory. CPU scheduling and file systems allow for virtual devices like card readers and printers to be provided to each virtual machine.
This document provides information about memory and devices on a PC. It contains sections that show memory load, usage and paging files to monitor memory, as well as a device summary to view what hardware is installed on the personal computer.

Managing airport and airspace data is no small task, especially when youre expected to deliver it in AIXM format without spending a fortune on specialized tools. But what if there was a smarter, more affordable way?
Join us for a behind-the-scenes look at how Sweco partnered with Swedavia, the Swedish airport operator, to solve this challenge using FME and Esri.
Learn how they built automated workflows to manage periodic updates, merge airspace data, and support data extracts all while meeting strict government reporting requirements to the Civil Aviation Administration of Sweden.
Even better? Swedavia built custom services and applications that use the FME Flow REST API to trigger jobs and retrieve results streamlining tasks like securing the quality of new surveyor data, creating permdelta and baseline representations in the AIS schema, and generating AIXM extracts from their AIS data.
To conclude, FME expert Dean Hintz will walk through a GeoBorders reading workflow and highlight recent enhancements to FMEs AIXM (Aeronautical Information Exchange Model) processing and interpretation capabilities.
Discover how airports like Swedavia are harnessing the power of FME to simplify aviation data management, and how you can too.

From Manual to Auto Searching- FME in the Driver's SeatSafe Software
油
Finding a specific car online can be a time-consuming task, especially when checking multiple dealer websites. A few years ago, I faced this exact problem while searching for a particular vehicle in New Zealand. The local classified platform, Trade Me (similar to eBay), wasnt yielding any results, so I expanded my search to second-hand dealer sitesonly to realise that periodically checking each one was going to be tedious. Thats when I noticed something interesting: many of these websites used the same platform to manage their inventories. Recognising this, I reverse-engineered the platforms structure and built an FME workspace that automated the search process for me. By integrating API calls and setting up periodic checks, I received real-time email alerts when matching cars were listed. In this presentation, Ill walk through how I used FME to save hours of manual searching by creating a custom car-finding automation system. While FME cant buy a car for youyetit can certainly help you find the one youre after!

The SQLExecutor is one of FMEs most powerful and flexible transformers. Pivvot maintains a robust internal metadata hierarchy used to support ingestion and curation of thousands of external data sources that must be managed for quality before entering our platform. By using the SQLExecutor, Pivvot can efficiently detect problems and perform analysis before data is extracted from our staging environment, removing the need for rollbacks or cycles waisted on a failed job. This presentation will walk through three distinct examples of how Pivvot uses the SQLExecutor to engage its metadata hierarchy and integrate with its Data Quality Management workflows efficiently and within the source postgres database. Spatial Validation Validating spatial prerequisites before entering a production environment.
