Software can be divided into two categories:

Helps the computer to carry out its basic operating tasks.

Interacts with the hardware.

Helps the user carry out a variety of tasks.

Interacts with the users.

The __________________ is a combination of programs designed to control and manage hardware and other resources of the system.

System software also manages the ______________ operations such as loading program and data into __________, saving data to disks, transmitting data through a port to a peripheral device, etc.

System Software is a program or a set of programs that primarily helps user perform certain task using a computer system.

Application softwares are downloaded and installed separately by the user and have nothing to do with the ______ functions.

Collection of computer programs that control the interaction of the user and the computer hardware.

Responsible for directing all computer operations and managing all computer resources.

The OS controls basic input and output, allocates ___________, manages _____________, maintains security, and detects equipment failure.

A part of the operating system code is stored in a ROM and the rest of it resides on a disk.

Loading the operating system into memory is called __________________.

Which of these are the responsibilities of an OS?

Which of these are responsibilities of OS?

The most important operating system capability for sharing computer resources is _______________.

Permits multiple programs to share a computer system’s resources at any time through concurrent use of CPU.

By concurrent use in multiprogramming, we mean that many programs are actually using the CPU at any given moment.

However, at the same time other programs can collect inputs and display outputs.

Two or more programs are active at the same time, but they do not use the same computer resources simultaneously.

With multiprogramming, a group of programs takes turns using the processor.

The first operating systems executed many programs at a time.

When a program read data from a tape or disk or wrote data to a printer, the entire CPU does not come to a stop.

In a multiprogramming environment, three programs were stored in primary storage.

The first program executes until an input/output statement occurs.

The multiprogramming capability of primarily single-user operating systems (PC).

One person can run two or more programs concurrently on a single computer.

Allows you to display both programs on the computer screen and work with them at the same time.

Virtual storage breaks a program into a number fixed- length portions called ________ or into variable-length portions called _______.

A way of handling programs more efficiently.

Only this small portion (____________) of the program is stored in primary memory at one time.

All other program pages are stored on a ____________ until they are ready for execution.

Which of these is not an advantage of virtual storage?

Virtual storage is based on the fact that. In general, only a few statements in a program can be actually utilized at any given moment.

An operating system capability that links together two or more CPU to work in parallel in a single computer system.

In ____________, OS can assign multiple CPUs to execute different instructions from the same program or from different programs simultaneously, dividing the work between the CPUs.

Uses concurrent processing with one CPU.

Uses simultaneous processing with multiple CPUs.

Device Driver can establish _______________ because it contains information about the characteristics of your computer and of the device.

Each peripheral device requires a device driver.

When we add a device to an existing computer, part of its installation includes adding its device driver to the _____________.

Developed for a specific task.

Is a prewritten, precoded, commercially available set of programs that eliminates the need for individuals or organizations to write their own software programs for certain functions.

General-purpose application packages that have been developed for PCs, especially word processing, spreadsheet, data management, graphics, integrated software packages, and Web browsers.

It allows you to make changes in your document electronically in memory.

Is a numerical analysis tool.

Creates a worksheet, composed of a grid of columns and rows.

Is a collection of information stored in one or more computers.

Is organized in a uniform format of records and fields.

It contains data that describes a collection of similar entities.

Allow us to create illustrations, diagrams, graphs, and charts that you also can print and transmit to remote computers.

Combines the functions of the most important PC software packages, such as word processing, spreadsheets, graphics, and data management.

Integrated packages are not a compromise.

Integrated Software Packages can do many things, however, they generally do not have the same power and depth as single-purpose packages.

Are collections of applications software sold as a unit (e.g. Microsoft Office 97). It contains Word, Excel, Access, PowerPoint, and Outlook.

Easy-to-use software tools for accessing the World Wide Web and the Internet.
