Cloud computing is a model for enabling ubiquitous, 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 or service provider interaction.

Cloud computing works on a client-server basis, using web browser protocols. The cloud provides server-based applications and all data services to the user, with output displayed on the client device. If the user wishes to create a document using a word processor, for example, the cloud provides a suitable application running on the server which displays work done by the user on the client web browser display. Memory allocated to the client system’s web browser is used to make the application data appear on the client system display, but all computations and changes are recorded by the server, and final results including files created or altered are permanently stored on the cloud servers. Performance of the cloud application is dependent upon the network access, speed and reliability as well as the processing speed of the client device.

ENIAC( Electronic Numerical Integrator And Computer) was the first general-purpose electronic computer. It was a Turing-complete digital computer capable of being reprogrammed to solve a full range of computing problems.^]

ENIAC was designed to calculate artillery firing tables for the United States Army’s Ballistic Research Laboratory. When ENIAC was announced in 1946 it was heralded in the press as a “Giant Brain”. It boasted speeds one thousand times faster than electro-mechanical machines, a leap in computing power that no single machine has since matched. This mathematical power, coupled with general-purpose programmability, excited scientists and industrialists. The inventors promoted the spread of these new ideas by teaching a series of lectures on computer architecture.

The ENIAC’s design and construction was financed by the United States Army during World War II. The construction contract was signed on June 5, 1943, and work on the computer began in secret by the University of Pennsylvania’s Moore School of Electrical Engineering starting the following month under the code name “Project PX”. The completed machine was announced to the public the evening of February 14, 1946 and formally dedicated the next day at the University of Pennsylvania, having cost almost $500,000 (nearly $6 million in 2010, adjusted for inflation). It was formally accepted by the U.S. Army Ordnance Corps in July 1946. ENIAC was shut down on November 9, 1946 for a refurbishment and a memory upgrade, and was transferred to Aberdeen Proving Ground, Maryland in 1947. There, on July 29, 1947, it was turned on and was in continuous operation until 11:45 p.m. on October 2, 1955.

ENIAC was conceived and designed by John Mauchly and J. Presper Eckert of the University of Pennsylvania.^[9] The team of design engineers assisting the development included Robert F. Shaw (function tables), Chuan Chu (divider/square-rooter), Thomas Kite Sharpless (master programmer), Arthur Burks (multiplier), Harry Huskey (reader/printer) and Jack Davis (accumulators).

The 2nd generation Intel® Core™ processor family brings visibly smart performance to your business PCs—delivering benefits you can readily see and appreciate. Users can be more productive. PCs and laptops can be better protected. Your operation can be a smooth-running machine. Clearly, 2nd generation Intel Core processors are the smart choice for  business.

Intelligence runs in the family

Smart performance is a trait of every member of the 2nd generation Intel Core processor family. That’s because every 2nd generation Intel Core processor features remarkably intelligent technologies. Examples?

• Intel® Turbo Boost Technology 2.0 automatically dials up the processor clock speed when demanding tasks require additional power, then dials down to save energy whenever possible.¹
• Intel® Hyper-Threading Technology (Intel® HT Technology) and other innovative Intel® technologies enable four-way (or eight-way) processing that makes multi-tasking between business applications quick and effortless.²

And smart performance is literally on display in 2nd generation Intel® Core™ processors, as they offer stunning visual performance due to built-in visuals . There’s no need for dedicated graphics cards (or the added cost and power requirements that come with them).³

Greater performance enables seamless security

Security shouldn’t get in the way of user productivity. And that’s another reason why the exceptional performance of 2nd generation Intel Core processors is so important. It enables security applications and protocols to run efficiently and unobtrusively in the background. In many cases, users won’t even know their PCs are actively being secured. And that’s the way it should be.

New PCs for Your New Compute Environment

IT is changing at warp speed, and PCs must keep pace. That’s why 2nd generation Intel® Core™ processors bring smart performance and new capabilities to secure mobility, online rich media, and business operations optimization.

Computer-aided design (CAD), also known as computer-aided design and drafting (CADD), is the use of computer technology for the process of design and design-documentation. Computer Aided Drafting describes the process of drafting with a computer.

CADD software, or environments, provide the user with input-tools for the purpose of streamlining design processes; drafting, documentation, and manufacturing processes. CADD output is often in the form of electronic files for print or machining operations. The development of CADD-based software is in direct correlation with the processes it seeks to economize; industry-based software (construction, manufacturing, etc.) typically uses vector-based (linear) environments whereas graphic-based software utilizes raster-based (pixelated) environments.

Virtual Memory

Virtual Memory is a feature of an operating system that enables a process to use a memory (RAM) address space that is independent of other processes running in the same system, and use a space that is larger than the actual amount of RAM present, temporarily relegating some contents from RAM to a disk, with little or no overhead.

ROM

ROM – Read-only memory: On ROM, data is prerecorded for read only which can not be removed. ROM is nonvolatile and it retains its contents regardless the computer is on or off. Most personal computers contain a small amount of ROM that stores critical programs such as the program that boots the computer. In addition, ROMs are used in calculators and peripheral devices such as laser printers, whose fonts are often stored in ROMs. There are a few variations of ROM such as programmable read-only memory(PROM), which is manufactured as blank chips on which data can be written with a special device called a PROM programmer.

RAM

RAM – Random access memory: whose contents can be accessed (read, write and remove) in any order. This is in contrast to sequential memory devices such as magnetic tapes, discs and drums, in which the mechanical movement of the storage medium forces the computer to access data in a fixed order. RAM is usually used for primary storage in computers to hold active information such as data and programs. Common forms of RAM are: SRAM (Static RAM) and DRAM (Dynamic RAM).

Cloud Computing is a technology that uses the internet and central remote servers to maintain data and applications. Cloud computing allows consumers and businesses to use applications without installation and access their personal files at any computer with internet access. This technology allows for much more efficient computing by centralizing storage, memory, processing and bandwidth.

Cloud computing is Internet-based computing, whereby shared resources, software, and information are provided to computers  and other devices on demand, like the electricity grid.

Cloud computing is a natural evolution of the widespread adoption of virtualization, Service-oriented architecture and utility computing. Details are abstracted from consumers,who no longer have need for expertise in, or control over, the technology infrastructure”in the cloud” that supports them. Cloud computing describes a new supplement, consumption, and delivery model for IT services based on the Internet, and it typically involves over-the-Internet provision of dynamically scalable and often virtualized resources
