Users prepare jobs on an off-line device like punch cards and submits to the computer operator. antivirus platform. It's as if some part of the computer suddenly raised its hand to ask for the CPU's attention in a lively meeting. When applications begin to be loaded into memory, the operating system assigns them an amount of memory. Then it turns control of the computer over to the operating system. Backup and Restore Manipulation of the file system. A. network executable file. Common names associated with someone who resolves common technical problems faced by computer users. when the process enters the system then it is put in a job queue. Reduction of the load on the host computer. Operating System 2.1.1 1. After allocating process p1 process and p2 process left 1MB and 2MB. If enough processes are started, and if the operating system hasn't been carefully designed, the system can begin to use the vast majority of its available CPU cycles to swap between processes rather than run processes. Once the POST has successfully completed, the software loaded in ROM (sometimes called the BIOS or firmware) will begin to activate the computer's disk drives. Client B. Operating system controls and coordinates the use of hardware among application programs. Example: Suppose there is a fixed partitioning is used for memory allocation and the different size of block 3MB, 6MB, and 7MB space in memory. The mapping from virtual to physical address is done by the memory management unit (MMU) which is a hardware device and this mapping is known as the paging technique. If the CPU supports virtual memory, the operating system doles out different groups of addresses (called address spaces) to operating system components and any executing applications. 5. A ____ boot is when you power on a computer that is off. The system software is a type of computer software that is designed for running the computer hardware parts and the application programs.

When a file cannot be saved on a single track across contiguous sectors and has to be broken up into small parts it is said to be ______. Disk Cleanup is a typical utility software. . Depending on the functionality, the system software can be further divided into two major categories; system management program and developing software. Scheduling queues refers to queues of processes or devices. Ranked in order of speed, the types of memory in a computer system are: High-speed cache: This is fast, relatively small amounts of memory that are available to the CPU through the fastest connections. manage resources run applications icon graphic representation for a program, type of file, or function pointer controlled by a mouse, trackpad, or touchscreen window rectangular area for displaying information and running programs menu provide a list of options or commands gesture control These virtual address spaces don't need to match the addresses of the computer's physical RAM. language translators allows different users to take advantage of the computer's resources simultaneously. look after the more critical process. The software that orchestrates this process is known as the memory manager or memory management unit (MMU). The DNA of an E. coli chromosome measures 1.6mm1.6 \mathrm{~mm}1.6mm in length, when extended, and 20A20 \text{\AA}20A in diameter. 2 Types of System Software 2.1 1. B. Show how the following floating-point additions are performed (where significands are truncated to 4 decimal digits). The TLB is an associative, high-speed memory. There are some aspects of system software that do not directly depend upon the type of computing system . 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. When you turn on the power to a computer, the first program that runs is usually a set of instructions kept in the computer's read-only memory (ROM). A physical address is computed by MMU. When an operating system manages the computer's memory, there are two broad tasks to be accomplished: is a computer program that operates or controls a particular type of device that is attached to a computer. A. Register contents 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.
