A _____ boot occurs when the computer is already on and you restart it without turning off the power. desktop operating systems - these are located on the computer's hard disk. 1. File mapping makes it possible to reduce the number of hard-disk accesses required to maintain memory resources, since the MMU now only writes modified data pages to the swap file. assembler (C). An OS acts an interface between a user and a device. 5. word processor (C). Utility software or utilities provide additional facilities to carry out tasks beyond the operating systems capabilities. File Management 2.1.4 4. A context switch is the mechanism to store and restore the state or context of a CPU in Process Memory management is the functionality of an operating system which handles or manages primary memory and moves processes back and forth between main memory and disk during execution. The system software act as a middle layer between the user applications and hardware. It also makes use of registers, stacks and queues within the CPU and operating-system memory space. In the most basic form, the bootstrap loader sets up the small driver programs that interface with and control the various hardware subsystems of the computer. What fraction of such a human cell is occupied by its DNA? What are operating systems? This frees up valuable disk space and improves system performances. When applications begin to be loaded into memory, the operating system assigns them an amount of memory. Main memory is associated with the processor, so moving instructions and information into and out of the processor is extremely fast. The heating element is modeled as shown in the figure. This software allows users to communicate with the device and perform the desired functions. Users prepare jobs on an off-line device like punch cards and submits to the computer operator. Moving information in RAM to hard disk (expanding RAM at no cost), Graphical User Interface (window, icons, pictures), a means of interacting with a computer program where the user (or client) issues commands to the program in the form of successive lines of text (commands), Files will always have an extension that shows the application it is associated with and what type of file it is, folders in GUI, directories in command line, start of the OS view, point where it starts looking for files and folders. Device manufacturers provide device drivers. The goal of the ______ utility program is to locate and eliminate unnecessary fragments and rearrange files and unused disk space. To keep track of used memory space by processes. When the process arrives and needs memory, we search for a hole that is large enough to store this process. Firmware: Firmware is known as permanent software or instructions stored in the motherboard storage or ROM (read-only memory) of the computer system. It also provides the platform for the running of other software. A. C. Network After that number of cycles, the operating system makes copies of all the registers, stacks and queues used by the processes, and notes the point at which the process paused in its execution.

When a computer is running virtualization softwares, it is operating as though it were two or more separate and independent computers known as _____. Software is created through the process of programming (we will cover the creation of software in more detail in chapter 10). This technique is called virtual memory management. 5. Invention of the computer How was the computer invented? Error detection. User at one site can use resources available at another. A list of files opened by the process A computer user must remove unnecessary files, i.e., the temporary files, as it speeds up the processing and improves the performance of the hard drive and computer. Therefore, each computer has its assembly language. It's as if some part of the computer suddenly raised its hand to ask for the CPU's attention in a lively meeting. Security: Prevents unauthorized access to programs and data using passwords. utilities He allowed free distribution of the operating system code and encouraged others to modify it. Schedulers are of three types First, we must install the devices driver on our computer before using it. B. With too little memory, the computer spends most of its time moving pages between memory and the swap file, a performance-sapping phenomenon called thrashing. one program can consume all the CPU time. A virtual cache uses a portion of physical memory to store code and data that the operating system might use frequently. For this, we search the entire list, unless the list is ordered by size. It was developed by Google and is free and open-source software that runs on a wide range of devices from smartphones to tablet computers, TV sets, video game consoles, digital cameras, medical equipment, and other electronics. These programs, along with the information they access, should be in the main memory during execution. There are some solutions to this problem: In the first fit, the first available free hole fulfills the requirement of the process allocated. The main aim of memory management is to achieve efficient utilization of memory. Moving pages to and from the swap file is slow, since a hard drive access is more than 1,000 times slower than a memory access. The System Software is a general-purpose software while the Application Software is specific purpose software. Here is a list important features of OS: Protected and supervisor mode.
