Get 10% off a custom domain and email address by going to https://www.hover.com/CrashCourse. So as you may have noticed from last episode, computers keep getting faster and faster, and by the start of the 1950s they had gotten so fast that it often took longer to manually load programs via punch cards than to actually run them! The solution was the operating system (or OS), which is just a program with special privileges that allows it to run and manage other programs. So today, we’re going to trace the development of operating systems from the Multics and Atlas Supervisor to Unix and MS-DOS, and take at look at how these systems heavily influenced popular OSes like Linux, Windows, MacOS, and Android that we use today.

[Recorded: May 9, 1963] This vintage film features MIT Science Reporter John Fitch at the MIT Computation Center in an extended interview with MIT professor of computer science Fernando J. Corbato. The film was co-produced by WGBH (Boston) and MIT. The prime focus of the film is timesharing, one of the most important developments in computing, and one which has come in and out of favor several times over the last several decades as the dichotomy between remote and centrally-managed computing resources played out; the latest incarnation for centrally-managed computing resources is known as cloud computing. Timesharing as shown in this film, was a novel concept in the early 1960s. Driven by a desire to more efficiently use expensive computer resources while increasing the interactivity between user and computer (man and machine), timesharing was eventually taken up by industry in the form of special timesharing hardware for mainframe and minicomputer computer systems as well as in sophisticated operating systems to manage multiple users and resources. Corbato describes how after the mid-1950s, when computers began to become reliable, the next big challenge to improve productivity and efficiency was the development of computer languages, FORTRAN being an example. One of the next bottlenecks in computing, according to Corabto, was the traditional batch processing method of combining many peoples computer jobs into one large single job for the computer to process at one time. He compares batch processing to a group of people catching a bus, all being moved at once. Timesharing, on the other hand, involves attaching a large number of consoles to the central computer, each of which is given a time-slice of the computers time. While the computer is rapidly switching among user applications and problems, it appears to the user that s/he has complete access to the central computer. Corbato then describes in technical detail a complex description of timesharing before showing some examples of timesharing from a terminal using a simple program to calculate a simple geometric problem (Pythagorean theorem). In the long run, Corbato says, timesharing will help address the increasing need for computer time and ease-of-use.

This talk proposes a scheme for addressing the operating system resource management problem. Resource management is the dynamic allocation and de-allocation by an operating system of processor cores, memory pages, and various types of bandwidth to computations that compete for those resources. The objective is to allocate resources for optimized responsiveness based on the finite resources available. Burton Smith,Technical Fellow, Microsoft Corporation Produced 11/29/2011

In this lecture you will learn about the concept of Direct Memory Access and how it works in Computer Architecture ? what are the services played by DMA and DMAC ? Definition: It is an operation in which data is copied (transported) from one resource to another resource in a computer system without the involvement of the CPU. DMA channels are used to communicate data between the peripheral device and the system memory. DMA channel enables a device to transfer data without involving the CPU to a work overload. In DMA, the interface transfers the data into memory and out from memory through memory bus. Direct memory access (DMA) is a method that allows an input-output (I/O) device to send or receive data directly to or from the main memory bypassing the CPU to speed up memory operations. The process is managed by a chip known as a DMA controller (DMAC). The task of a DMA-controller (DMAC) is to execute the copy or operation of data from one resource location to another. The copy of data can be performed from: - I/O-device to memory - memory to I/O-device - memory to memory - I/O-device . Note : CPU and DMA perform their task without interfering to each other. The CPU copies every piece of data using a peripheral bus from the I/O device. Using a peripheral, the bus occupies the CPU during the read/write process and does not allow other work to be performed until the operation is completed. The cpu, initiates the transfer by supplying the interface with the starting address and data to be transferred and then proceed to execute other task. when transfer is made , the DMA requests memory cycles via memory bus . When the request is granted by memory controller, The DMA transfers the data directly into memory. With DMA, the CPU can process other tasks while data transfer is being performed. The transfer of data is first initiated by the CPU. During the transfer of data between the DMA channel and I/O device, the CPU performs other tasks. When the data transfer is complete, the CPU receives an interrupt request from the DMA controller. Direct Memory Access (DMA) is a capability provided by some computer bus architectures that allows data to be sent directly from an attached device (such as a disk drive) to the memory on the computer's motherboard. The microprocessor is free from involvement with the data transfer, thus speeding up overall computer operation. Working of DMA : CPU communicates with DMA through Data & Address Bus. The CPU initialize the DMA through Data bus. Once the DMA receives the start command , it can start the data transfer between I/O device and memory. When I/O device sends a DMA request, DMAC activate the BR line, informing the cpu to relinquish(claim) the buses. The cpu responds with its BG line, informing the DMA that its buses are disabled. The DMA then puts the current value of its address register into address bus, initiates the RD or WR signal, and sends to I/O and DMA receives acknowledge from I/O device. When BG=0, the RD / WR are Input line that allow the cpu to communicate with internal DMA register. When BG=1, the RD/ WR are Output lines from DMAC to RAM “to specify Read or write operation for data”. When I/O device receives an acknowledge from DMAC ,it transfer the data or access memory directly and execute , while the CPU is busy in other task execution BR= Bus request , BG=Bus Grant, DS=DMA select , RS= Register Select For mor videos subscribe the channel : Computer science academy by Dinesh Sir

-~-~~-~~~-~~-~- Please watch: "Top 10 Asian Scientist" âž¨ https://www.youtube.com/watch?v=kNgEXbtjFIQ -~-~~-~~~-~~-~- An operating system (OS) is system software that manages computer hardware and software resources and provides common services for computer programs. The operating system is a component of the system software in a computer system. Application programs usually require an operating system to function. Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time, mass storage, printing, and other resources. For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware, although the application code is usually executed directly by the hardware and frequently makes system calls to an OS function or is interrupted by it. Operating systems are found on many devices that contain a computer—from cellular phones and video game consoles to web servers and supercomputers. Examples of modern operating systems include Apple OS X, Linux and its variants, and Microsoft Windows.

Windows is full of annoying little errors and "Out of virtual memory" is one of them. Usually your PC starts freezing first. Then an error appears and tells you that your virtual memory is too low. In this article we are going to explain what causes this error and how to fix it once and for all. What is virtual memory? Virtual memory, also known as page file or swap file, is a file on your hard disk that Windows uses in addition to physical memory (RAM) whenever the need arises. For example, when you are running an application or a process your RAM can’t handle, virtual memory is there to help. Usually the page file is 1.5 times the amount of physical memory, i.e. a system with 512 MB of RAM will have 768 MB page file. This tutorial will apply for computers, laptops, desktops,and tablets running the Windows 10, Windows 8/8.1, Windows 7 operating systems.Works for all major computer manufactures (Dell, HP, Acer, Asus, Toshiba, Lenovo, Samsung).

It's a platform for managing, storing, and processing data online through the internet. Some of the cloud computing features include the following: - On-Demand Services – Available when you need it - Network Access – When using the internet as your medium - Shared Resources – All resources are gathered together and used by multiple customers - Scalability - The ability of a computer system to adapt to increasing demands The Three Delivery Models: Cloud computing provides different services based on three delivery configurations. When they are arranged in a pyramid structure, they are in the order of SaaS, PaaS, and IaaS. The Three Services: #SaaS - Software as a Service This service provides on-demand pay per use of the application software for users and is independent of a platform. You do not have to install software on your computer, unlike a license paid program. Cloud runs a single occurrence of the software, making it available for multiple end-users allowing the service to be cheap. All the computing resources that are responsible for delivering SaaS are totally managed by the vendor. The service is accessible through a web browser or lightweight client applications. End customers use SaaS regularly. The most popular SaaS providers offer the following products and services: Google Ecosystem including Gmail, Google Docs, Google Drive, Microsoft Office 365, and SalesForce. #PaaS - Platform as a Service This service is mostly a development environment that is made up of a programming language execution environment, an operating system, web server, and database. It provides an environment where users can build, compile, and run their program without worrying about an hidden infrastructure. You manage the data and application resources. All the other resources are managed by the vendor. This is the realm for developers. PaaS providers offer the following products and services: Amazon Web services, Elastic Beanstalk, Google App Engine, Windows Azure, Heroku, and Force.com #IaaS - Infrastructure as a Service This service provides the architecture and infrastructure. It provides all computing resources but in a virtual environment so multiple users can have access. The resources include data storage, virtualization, servers, and networking. Most vendors are responsible for managing them. If you use this service, you are responsible for handling other resources including applications, data, runtime, and middleware. This is mostly for SysAdmins. IaaS providers offer the following products and services: Amazon EC2, Go Grid, and Rackspace.com. Here is a short list of some companies that use cloud computing: iCloud – Cloud from Apple is for Apple products. You can backup and store everything from multimedia to documents online. The content is then smoothly integrated onto your devices. Amazon's AWS - When you talk about companies using cloud computing, Amazon Web Services leads the pack. It offers IaaS and PaaS to all their customers. Google Cloud – This cloud platform is universal for Google's enormous ecosystem and for other products such as Microsoft Office. It provides storage of data and collaboration along with other services that are included in their cloud computing suite. Microsoft Azure – Offered by Microsoft, it provides SaaS, PaaS, and IaaS for its software and developer tools. If you have used Office 365, then you have used SaaS. IBM Smart Cloud - This offers private, public, and hybrid distribution platforms providing a full range of SaaS, PaaS, and IaaS cloud computing services for businesses. The pay as you go platform generates profits for IBM. New technology is popping up all over the internet and Cloud seems to be on the rise. This is only scratching the surface on what is already available and what will become available throughout 2017. --- 3 Types of Cloud Computing Services - IaaS PaaS SaaS Explained https://www.youtube.com/watch?v=36zducUX16w #CloudComputingServices #CloudComputing --- Follow us on https://www.facebook.com/EcourseReviews https://twitter.com/EcourseReviews https://plus.google.com/+Ecoursereview/posts https://ecoursereview.com/

Operating System Concepts: What is an OS (Definition) Video Transcript: Now this is the starting point for anyone who needs to study operating systems. This is the most basic question that will come to your mind. So let's deal with this question first. In this video, we will discuss two topics to understand what is an operating system. First, we will have a look at the definition of an operating system and We will try to understand the meaning of operating system. And in the second topic, we will see where exactly an operating system fits in a computer system. This will help us understand the role played by an operating system in the functioning of a computer. so let's start. Whenever you switch on your laptop, desktop, tablet or even a mobile phone, you might have observed that it takes some time to load your home screen. Here, Your device is starting a software in the background, and this software will help you control your computer or mobile device and lets you run other applications on top of it. This software will be running as long as your device is running and stops when your device shuts down. If you are even remotely a Tech savvy person, you will know what this software is. It is an operating system. To define it formally, An operating system is an important piece of program that manages the computer hardware and other software applications. Using an operating system you can utilize the hardware components like CPU, memory, Input and output devices like keyboard, mouse etc. So therefore, an operating system also acts as an intermediate between the computer hardware and you, the computer user. You can say It acts as a middle man. This is because, The user cannot give commands directly to the CPU in machine language, nor can the CPU interact with the user directly. So there needs to be a middle man which communicates and translates all interactions between the user and the CPU. Now let’s see where exactly the operating system fits in the overall computer system structure. A computer can be divided into four components. At the core we have the hardware, which comprises of CPU, memory and other I/O devices. On top of this, there is an operating system, which controls and co ordinates the use of hardware by various applications. Application programs are the software tools or utilities which the users run to carry out their tasks. These programs can utilize the hardware resources through the help of operating systems. Some examples of application programs are the word processors, spread sheets, compilers and even the browser you have opened right now to watch this course. And finally on the other end, we have the real computer users, who interact with computer in order to get some tasks performed. So based on this figure, you can see that the operating system occupies a crucial spot in the architecture of a Computer System. And without operating systems, it would be very difficult to utilize a computer effectively.

Top 5 Technologies in 2019 : https://youtu.be/aCY1GyKVpBw Python Tutorial for Beginners: https://goo.gl/cLKYQP 5 skills for IT Professional: https://goo.gl/ba6Ui7 Top 5 technologies to learn in 2018. Technologies are : IoT (Internet of Things) Cloud Computing Blockchain Artificial Intelligence Big Data IoT : The Internet of things (IoT) is the network of physical devices, vehicles, home appliances and other items embedded with electronics, software, sensors, actuators, and network connectivity which enables these objects to connect and exchange data. The IoT allows objects to be sensed or controlled remotely across existing network infrastructure. Cloud Computing: Cloud computing enables ubiquitous access to shared pools of configurable system resources and higher-level services that can be rapidly provisioned with minimal management effort, often over the Internet. Cloud computing relies on sharing of resources to achieve coherence and economy of scale, similar to a utility. Third-party clouds enable organizations to focus on their core businesses instead of expending resources on computer infrastructure and maintenance. Cloud providers typically use a "pay-as-you-go" model. Blockchain: A blockchain is a continuously growing list of records, called blocks, which are linked and secured using cryptography which is resistant to modification of the data. Each block typically contains a hash pointer as a link to a previous block, a timestamp and transaction data. Blockchains are secure by design and are an example of a distributed computing system The first blockchain was conceptualized in 2008 by an anonymous person or group known as Satoshi Nakamoto and implemented in 2009 as a core component of bitcoin where it serves as the public ledger for all transactions. Artificial intelligence: AI is intelligence displayed by machines. In computer science, AI research is defined as the study of "intelligent agents": any device that perceives its environment and takes actions that maximize its chance of success at some goal. Colloquially, the term "artificial intelligence" is applied when a machine mimics "cognitive" functions that humans associate with other human minds, such as "learning" and "problem-solving Big Data: Big data is data sets that are so voluminous and complex that traditional data processing application software is inadequate to deal with them. Big data challenges include capturing data, data storage, data analysis, search, sharing, transfer, visualization, querying, updating and information privacy. There are three dimensions to big data known as Volume, Variety and Velocity. Editing Monitors : https://amzn.to/2RfKWgL https://amzn.to/2Q665JW https://amzn.to/2OUP21a.

In this deadlock in OS video tutorial, we will understand what is a deadlock in Operating systems, what are the conditions that result in deadlocks & strategies for handling deadlocks. Deadlocks in OS - A process in operating systems uses different resources and uses resources in following way. 1) Requests a resource 2) Use the resource 2) Releases the resource Deadlock is a situation where a set of processes are blocked because each process is holding a resource and waiting for another resource acquired by some other process. Deadlock can arise if following four conditions hold simultaneously (Necessary Conditions) - 1) Mutual Exclusion: One or more than one resource are non-sharable (Only one process can use at a time) 2) Hold and Wait: A process is holding at least one resource and waiting for resources. 3) No Preemption: A resource cannot be taken from a process unless the process releases the resource. 4) Circular Wait: A set of processes are waiting for each other in circular form. Methods for handling deadlock - There are three ways to handle deadlock 1) Deadlock prevention or avoidance - The idea is to not let the system into deadlock state. 2) Deadlock detection and recovery - Let deadlock occur, then do preemption to handle it once occurred. 3) Ignore the problem all together - If deadlock is very rare, then let it happen and reboot the system. This is the approach that both Windows and UNIX take. Following three strategies can be used to remove deadlock after its occurrence - 1) Preemption - We can take a resource from one process and give it to other. This will resolve the deadlock situation, but sometimes it does causes problems. 2) Rollback - In situations where deadlock is a real possibility, the system can periodically make a record of the state of each process and when deadlock occurs, roll everything back to the last checkpoint, and restart, but allocating resources differently so that deadlock does not occur. 3) Kill one or more processes - This is the simplest way, but it works.

Attend Question/ Answer MEETUP: http://goo.gl/kPHGFw Follow Eli on the Vlog Channel: https://www.youtube.com/user/EliCompu... Info Level: Beginner Presenter: Eli the Computer Guy Date Created: February 2, 2012 Length of Class: 59 Minutes Tracks Virtual and Cloud Computing Prerequisites Introduction to Cloud Computing Purpose of Class This class teaches students the basic concepts that required to deploy Virtualization in the real world. Chapters Introduction (00:00) Overview (01:10) Type 1 Hypervisors (13:45) Type 2 Hypervisors (33:31) Converting to Virtualization (40:51) Final Thoughts (47:05) Class Notes Introduction Virtualization allows you to separate the Operating System from the underlying hardware Virtualization is NOT the same as Cloud Computing. Virtualization is a Type of Cloud Computing. Hypervisors are the software that Operating System "Instances" run on. Overview Virtualization allows you to easily migrate servers between pieces of physical hardware Virtualization allows you to consolidate multiple cheap physical servers into one server An "Instance" is a "Virtual Computer" installed on a Hypervisor. Type 1 Hypervisors Called Bare Metal Hypervisor Installs directly on to hardware You use Management Software installed on a different computer to manage a Type 1 Hypervisor box. Based on XEN. Generally the Hypervisor is free, but you pay for the Management software Over Allocation allows you to allocate more total resources to the Instances of the operating systems then the physical server has. At any one time all Instances CANNOT use more resources then the total amout that the server has. Type 2 Hypervisors Called Hosted Hypervisor Type 2 Hypervisors are installed onto an Operating System such as Windows 7, OSX or Linux. (VirtualBox, Virtual PC) Be careful allocating resources to virtual machines. You have the ability to allocate so many resources to the virtual machines that you crash the host machine. Networking can start acting "weird" on the host machine when Virtual Machines are running Converting to Virtualization Vendors of Virtualization software have "conversion" software that will convert an Operating System that installed on a Physical Computer into a Virtual Machine Many pieces of Backup Software no backup servers directly into a Virtual Machine. Final Thoughts... Be careful of licensing!!! Per Server/ Per Socket/ Per Core Virtualization software is stable, and not "cutting" or "bleeding" edge technology.

This lecture is dedicated to students and learners those are eager to know the concept of Program I/O operations in computer architecture. By seeing this lecture you will be able to understand the concept of Data Transfer in cpu. what is it and its significance and different types. Data Transfer in CPU : Computer system resource tools are used for communication/Data Transfer between hardware and software. Data Transfer to and from peripherals may be handle in following modes/ way: Program I/O operations Interrupt Initiated I/O Direct memory access (DMA). Program I/O operations: It is the result of instruction, written in program. Each data transfer is initiated by an instruction in the program (cpu registers and peripherals). I/ o device does not have direct access to memory , all execution happens via cpu instructions. In this method, the cpu stays in a program loop until the I/O device indicates that is ready for data transfer. Ex: Data transfer from I/O device through CPU:I/ o device does not have direct access to memory , all execution happens via cpu instructions. Working flow of Diagram (Program I/O operations):Step1 :The I/O device transfer bytes of data one at a time as they have, the i/o device place the byte in I/O bus and enables its data valid line. Step2: The interface accept the data into its data register and enables the data accepted line. Step3: The interface set a bit in the status register that we will refer ‘F’ or flag bit. The device can now disable the data valid line .Step4: The transfer of each byte / date requires 3 instructions / steps : . Read the status register.. Check the status of flag bit.. Read the data register.Each byte is read into CPU register and then transferred to memory with a stored instruction. Draw back: In this method, the CPU stays in program loop until the i/o unit indicates that it is ready for data transfer. This is a time consuming process since it keeps the processor busy unnecessary. For more videos subscribe the channel and press the bell icon for notification.
