Software, Programs and Support Modules

When the user begins to interact with the computer, the software being used will send out a system call that will specify a task that a hardware component must perform in order for the software to continue functioning and send further requests,

The Operating System manages the flow of data and tells the processor what component needs to be doing. It does this my relaying one piece of information at a time but done so fast it seems it is doing it all at the same time. It does this by giving the information to the processer in computer language, so it can understand.

Assorted programs that direct the performance and computing functions for a specific or specialized use of Information Systems:

A computers operating system (OS) is the core of the computer and is more than just software. The OS controls the computer’s memory and processes as well as its hardware and software. It is the brain of the computer. Software applications on the other hand perform a certain task. Ex. Google Chrome provides internet and Adobe allows PDF files to be read (among other things). The OS is what makes all of these applications work successfully and accomplish whatever the application is designed to accomplish.

This is a microprocessor that allows the computer to boot up. It also allows data manigment between the operating system.

Graphical user interface, a GUI (pronounced as either G-U-I or gooey ) allows the use of icons or other visual indicators to interact with electronic devices , rather than using only text via the command line . For example , all versions of Windows utilize a GUI whereas MS-DOS does not . The GUI was first developed at Xerox PARC by Alan Kay , Douglas Engelbart , and a group of other researchers in 1981. Later , Apple introduced the Lisa computer , the first commercially available computer , on January

Function- responsible for storing all documents and data, including files, the operating system and more.

List and describe at least three types of storage that is typically included in all computer systems.

Hardware refers to the physical components of a computer or other device. An example of hardware could be a printer. Software is the set of instructions that allows a particular program to complete at ask. An example of software could be operating systems, such as Windows, Linux, and Mac OS

This section gives the details and specification of the software on which the system is expected to work.

Identifying and describing key features of operating systems and common application software as they relate to the management of information.

CPU: Central Processing Unit process the basic instructions from the computer. Processor is heart of the computer because it tells the computer what to do and when to do. The priority of the instructions is given by the processor to computer.

When looking at an Operating System one could often say that an Operating System is a large sum made up of small separate parts. Much like how Knuth describes computer science being the “wall of mini stones”. The Operating System, or the “OS” can be defined as “software that communicates with the hardware and allows other programs to run”. (TechTerms.com, 2012) The Operating System makes use of two modes known as User Mode and Kernel Mode in order to

A computer is an electronic device that stores, retrieves, and processes data, and can be programmed with instructions. A computer is composed of hardware and software, and can exist in a variety of sizes and configurations. Hardware is the physical equipment of a computer system, including the central processing unit (CPU), data-storage devices, terminals, printer, etc. Software is a program or set of instructions or rules that control the operation of a computer.

When you start a pc with an OS, it allows you to do projects like:
