Random-access memory (RAM)- A type of short-term memory computer memory used by computers, primarily used as a temporary working memory by the CPU.

What is cloud computing? Cloud Computing is storing and accessing applications and data over the Internet and not locally of your computer’s hard drive. The concept has been around and in use for years. To put it more simply, cloud computing means providing processing power to electronic devices (PCs, tablets, smartphones) via a remote infrastructure. There are some advantages and disadvantages of using cloud computing in a business environment. I will be describing three advantages and three disadvantages of using cloud computing in everyday business.

The RFID technology consists of three kinds of tags i.e. active RFID tags, passive RFID tags, and battery

System software:The programs that control and manage the basic operations of a computer are generally referred to as system software. System software typically includes the following types of programs: operating systems, utility programs, software development

SaaS – Software as a Service – Users on the service are given access to the application’s software and databases, cloud providers manage the infrastructure and platforms that run the application. “On demand”.

The SaaS model offers a few key advantages. The cost of entry is lower, which lets more people access the software. The burden of updates, security, and maintenance fall on the company offering the service.

Traditionally, it can suck up far too much of your business’ time and effort. This doesn 't add value, and takes the fun out of being in business. Cloud software can save your company time and money. Think about when you use internet banking. Every time you access this data, you’re using the cloud. The cloud is a platform to make data and software accessible online anytime, anywhere, from any device. Your hard drive is no longer the central hub. You can use cloud-based software from any device with an internet connection

Cloud computing is a shift in a new way of thinking that believes in data sharing & computations over a cloud or network of potential nodes This network consists of data centers, computers, and web services in order to make the cloud work. An application based on such clouds is taken as a cloud application. Cost Efficient: , in conjunction with the Manchester Business School and Vanson Bourne recently conducted a survey of 1,300 companies in the U.K. and U.S., supplemented by qualitative telephone interviews by the Manchester Business School with companies that used the cloud during December 2012 and January 2013.study found that 88 percent of cloud users pointed to cost savings and 56 percent of respondents agreed that cloud services have helped them boost profits.

RFID or Radio-Frequency Identification as the name suggests uses Radio frequency for identification of a particular object. It is similar to a bar-code, scans to retrieve a particular and unique information for identification. It consists of a chip, capable of carrying a maximum of 2000 bytes of data and an antenna uses electronic devices (small in size). The major feature of RFID above other electronic identification mechanisms is that the RFID device need not be precisely positioned wrt the scanner.

Cloud computing, a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort of service provider interaction. From a user 's perspective, cloud computing is the use of the application without having to understand the mechanics involved in implementing it and making it accessible. From an IT perspective, it is the opposite end of the spectrum. For IT professionals, cloud computing means understanding how to deliver the experience and meet other business goals such as service level agreements (SLAs), reducing costs, compliance

Summary – Cloud computing facilitates any organization with efficient data storage and management reducing company 's recurring cost and thereby increasing ROI.

Software as a Service (SaaS), sometimes referred to as "on- demand software" is a software delivery model in which software and associated data are hosted on the cloud. SaaS is typically accessed via a web browser and is paid on a subscription basis, monthly or yearly as per requirement.

Cloud Computing is the use of common software, functionality or business applications from a remote server that is accessed via the Internet. Basically, the Internet is the "cloud" of applications and services that are available for access by subscribers utilizing a modem from their computer. With Cloud Computing, one simply logs into desired computer applications - such as sales force or office automation programs, web services, data storage services, spam filtering, or even blog sites. Generally, access to such programs is by monthly or annual paid subscription. Through Cloud Computing, businesses may prevent financial waste, better track

This technology consists of three parts: a reader, antenna, and a tag. The readers has a microprocessor that is connected to an external computer. A radio frequency antenna is connected to the reader and is used to transmit wireless radio signals to the tag. This antenna also receives radio signals reflected by a tag’s antenna in response. The tag has an inbuilt antenna which receives radio signals from a reader, a rectifier which converts the received signal to provide power to the tag and a

2.1 Cloud Software-as-a-Service: The software as service architecture gives access to a software infrastructure, which is remotely accessed via the web, based services. In this infrastructure, it is important to note that the service provider is responsible for managing the infrastructure. This architecture allows companies to get the business functionality of software by incurring a minimal cost, which is less than paying for the licensed applications. It follows the pay as you go, model. Software-as-a-Service eliminates all possibilities for organizations to handle the installation, set-up, daily preservation and maintenance.
