Name the characteristics cloud computing ?
To get a common understanding on cloud computing let’s start with the basics:the essential characteristics and service and deployment models.Forthis,we will rise one of the standardization bodies described earlier NJST to be more specific,as the NJST definition hoy become the de facto definition of cloud computing.
Cloud computing is a model for enabling ubiquitius,convenient,on-demand network access to a shared pool of configurable computing recources (e.g.networks,servers,storage,applications and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.Although this widely-adopted description of what makes a cloud computing solution is very valuable it is not very tangible or easy to understand.So let’s dive a little deeper into cloud computing and why it’s different than just visualization alone,which iscommonly,mistaken to be cloud computing as well.The following image shows that cloud computing is composed of like essential characteristics,three deployment models,and four service models,as shown in the following figure:
Cloud computing&: 1.Automation
2.Virtualization
3.Standardization
4.Characteristic- On demand seft-service;Broad network access;Resource
pooling;Rapidelasticity;Measured service
5.Deployment models- Public cloud;Privatecloud;Hybrid cloud
6.Service models- Business process as a service; software as service; platform as a
service
What is mobile technologies.
Mobile technology is the technology used for cellular communication. Mobile code division multiple access (CDMA) technology has evolved rapidly over the past few years. Since the start of this millennium, a standard mobile device has gone from being no more than a simple two-way pager to being a mobile phone, GPS navigation device, an embedded web browser and instant messaging client, and a handheld game console. Many experts argue that the future of computer technology rests in mobile computing with wireless networking. Mobile computing by way of tablet computers are becoming more popular. Tablets are available on the 3G and 4G networks.
What is Multimedia Technologies?
Multimedia technology refers to interactive, computer-based applications that allow people to communicate ideas and information with digital and print elements. Professionals in the field use computer software to develop and manage online graphics and content. The work that media technology specialists produce is used in various media, such as training programs, web pages, and news sites.

Computer-based, interactive applications having multiple media elements, including text, graphics, animations, video, and sound. Multimedia technology refers to both the hardware and software used to create and run such systems.
The mode of delivery for each application depends on the amount of information that must be stored, the privacy desired, and the potential expertise of the users. Applications that require large amounts of data are usually distributed on CD-ROMs, while personal presentations might be made directly from a computer using an attached projector. Advertising and some training materials are often placed on the WWW for easy public access. Museums make use of multimedia kiosks with touch screens and earphones.
Multimedia products may be created and run on the commonly used computer environments. Multimedia system users may employ a variety of input devices in addition to the keyboard and mouse, such as joysticks and trackballs. Touch screens provide both input and display capabilities and are often the choice when potentially large numbers of novices may use the system. Other display devices include high-resolution monitors and computer projectors. Generally the abundance of graphics and video in multimedia applications requires the highest resolution and deepest color capacity possible in display devices.
Input devices for the creation of multimedia applications include graphics tablets, which are pressure-sensitive surfaces for drawing with special pens; digital cameras, which take pictures electronically; and scanners, which convert existing pictures and graphics into digital form. Other hardware devices, such as a video card and video digitizing board, are required both to create and to play digital video elements.
The hardware for incorporating sound elements into multimedia systems includes microphones, voice-recognition systems, sound chips within the computer, and speakers, which come in a wide variety of forms with varying capabilities and quality.
The future of multimedia technology is dependent upon the evolution of the hardware. As storage devices get faster and larger, multimedia systems will be able to expand, and increased use of DVD should result in improved quality. Rising network speeds will increase the possibility of delivering multimedia applications over the WWW. Currently, Virtual Reality Modeling Language (VRML) is used for some WWW applications and may drastically expand the multimedia experience. Virtual reality is becoming more realistic and will stretch the multimedia experience to envelop the user. The one certainty in multimedia
