Their vision is “To create a better everyday life for many people”. Their business idea is “to offer a wide range of well-designed, functional home furnishing products at prices so low that as many people as possible will be able to afford them”.

Q. Identify 2-3user interface requirements of IKEA.

3. External Interface Requirements
3.1 User Interfaces
<Describe the logical characteristics of each interface between the software product and the users. This may include sample screen images, any GUI standards or product family style guides that are to be followed, screen layout constraints, standard buttons and functions (e.g., help) that will appear on every screen, keyboard shortcuts, error message display standards, and so on. Define the software components for which a user interface is needed. Details of the user interface design should be documented in a separate user interface specification.>
3.2 Hardware Interfaces
<Describe the logical and physical characteristics of each interface between the software product and the hardware components of the system. This may include the supported device types, the nature of the data and control interactions between the software and the hardware, and communication protocols to be used.>
3.3 Software Interfaces
<Describe the connections between this product and other specific software components (name and version), including databases, operating systems, tools, libraries, and integrated commercial components. Identify the data items or messages coming into the system and going out and describe the purpose of each. Describe the services needed and the nature of communications. Refer to documents that describe detailed application programming interface protocols. Identify data that will be shared across software components. If the data sharing mechanism must be implemented in a specific way (for example, use of a global data area in a multitasking operating system), specify this as an implementation constraint.>
3.4 Communications Interfaces
<Describe the requirements associated with any communications functions required by this product, including e-mail, web browser, network server communications protocols, electronic forms, and so on. Define any pertinent message formatting. Identify any communication standards that will be used, such as FTP or HTTP. Specify any communication security or encryption issues, data transfer rates, and synchronization mechanisms.>

Answer 1

Answer-

User interface requirements of IKEA -

• The hardware , a computer also needs a set of programs-an operating system - to control the devices.this page will discuss the following :
• There are diffrent kinds of operating systems:such as windows,linux,and MAc os
• There are also diffrent versions of these operating systems,e.g windows 7,8, and 10
• Operating systems can be used with diffrent user interfaces (UI):text user interfaces (TUI) and graphical user interfaces (GUI)as examples
• Graphical user interfaces have many similarities in diffrent operating systems:such as the start menu,dekstop etc.

When you can recognize the typical parts of each opearting systems user interface,you will mostly be able to use both windows and linux as well as eg. Mac os.

THE ROLE OF OPERATING SYSTEM IN THE COMPUTER

An operating system (os)is a set of programs which ensures the interoperability of the hardware and software in your computer.the operating system enables,among other things,

• The identification and activation of devices connected to the computer,
• The installation and use of programs, and
• The handling of files.

USER INTERFACES

A user interface(UI) refers to the part of an operating system,program,or device that allows a user to enter and recieve information.Aa text -based user interface displays text,and its commands are usually typed on a command line using a keyboard.with a graphical user interface ,the functions are carried out by clicking or moving buttons,icons and menus by means of a pointing device.

The images contain the same information : a directory listing of a computer.you can often carry out the same tasks regardless of which kind of UI you are using.

TEXT USER INTERFACE(TUI)

Mordernn graphical user interfaces have evolved from text-based UIs. some operating systems can still be used with a text - based user interface.In this case,the commands are entered as text(eg.,"cat story.txt").

GRAPHICAL USER INTERFACE

In most operating systems,the primary user interface is graphical,i.e. instead of typing the commands you manipulate various graphical objects with a pointing device.The underlying principle of different graphical user interfaces(GUIs) is largely the same ,so by knowing how to use a windows UI, you will most likely know how to use linux or some other GUI.
