The use of the computer has had a dramatic impact on everything we as individuals and businesses do since its inception. Computers have gone from being the size of an entire room to something that can be held in your hand. They have also become a main source of storage. The need for storage has grown by leaps and bounds as more types and amounts of data are transferred and stored. Words, images, streaming video are all types of storage that are being housed on networks today. One of the earliest forms of data storage was the punch card. Punch cards were perforated paper that stored patterns that were used on cloth to make designs. They were then able to store data, but could not hold much. Their primary use was to store computer settings for different machines making for easier programming. Then came punched tape, magnetic tape and compact cassettes, all of which were used to store data on PCs. Then the floppy disk arrived on the storage scene. Originally they were designed to replace the tape drives on computer systems. Tape drives are still used today for the back-up of data. Floppy disk started out almost the size of a piece of paper, eight inches (Watson, 2010). They were quite large. Over time, the floppy disk reduced in time. They went from eight inches to 5.25 inches then finally down to 3.5 inches. The amount of data stored on a floppy disk was small compared to today’s standards. At that time, most data being stored was simply words and pictures. Floppy disks were sufficient space. Users had to physically carry the disks from user to user within a company. Luckily, they were within close proximity as networks were still fairly young. Storage Technology has changed the way businesses performed their da... ... middle of paper ... ... Norall, S. (2007).

Hard Disk Drive (HDD) - Hard drives can store very large amounts of data ranging from 200GB – 1TB. A hard drive is made up of a magnetic disk that consists of a number of platters/disks that are coated in a magnetic material that rotate at 7200 RPM. The data is encoded into bits and written into the disks as a series of changes in the direction of the magnetic pull, and then the data is read by detecting the changes in direction on the
DataClear had also recorded very impressive sales growth in its first two years and, given the projections, were looking at 300 percent average revenue growth thru '02. The case analysis available shows that DataClear has a $600 million annual domestic market for its current product and $1.2 billion when you add in the global market in telecommunications and financial services. With product expansion, there was a potential annual $2.7 billion market ($1.5billion domestic/$1.26 billion abroad) to target in the telecommunications, financial services, chemical, petrochemical, and pharmaceutical industries combined.
The memory capacity of that time was rather limited. “There were not many external drives, the only external drives of that time were I/O cards, I cards and O cards”
In an attempt to increase the market share with in the digital memory division (DMD) of Hewlett-Packard, management decided to analyze the potential profitability of developing a 1.3” drive that would surpass the current technology within this continually growing market. Teams comprised of the best and brightest employees, within the organization, were tasked with developing this new product from the ground up. After successfully delivering on their goals, the new drive was ready for the customer. Initial sales were one tenth of the prescribed figures and the 1.3” drive was scraped, even though it was a far superior product to the current technology available at the time of introduction. Throughout this case study I will outline the reasons this project ultimately failed and discuss how some of the mistakes that lead to the drives demise were actually rational decisions.
As examined earlier, TCS specializes in storage and organization solutions to help customers simplify their lives. Although, TCS is in a very niche market, they maintain several key advantages that help to fight off competition and draw customers back time after time.
Nowadays, people are living in the data world. It’s not easy to measure the total volume of data stored electronically, but an IDC estimate put the size of the “digital universe” at 0.18 zettabytes in 2006, and is forecasting a tenfold growth by 2011 to 1.8 zettabytes. A zettabyte is 〖10〗^21 bytes, or equivalently one thousand exabytes, one million petabytes, or one billion terabytes. That’s roughly the same order of magnitude as one disk drive for every person in the world [1].

Storage devices are used to record or retrieve data in technological devices. A device that only records information is called a recording medium; it does not allow for processing of the information. They allow for ease of access for the user to retrieve any data from the device that had been previously stored. They help run programs, view page content, and even allow for interaction on some web pages. There are two types of storage in computers; a primary storage, like RAM, or Random Access Memory, and a secondary storage, like a hard drive. Without storage devices, computers would not function as efficiently as they do.
With the evolution of Cloud and Mobile computing, the Moore’s law and Law of Mass Digital Storage are effected by a significantly.
The author discusses while relational databases will be around for quite a while, their overall peak may be on the decline due to non-relational databases. The age of relational databases is starting to show because of they require specific memory and disk requirements; however, as computer technology advances for memory and disks, the requirements are lessening. Non-relational databases, such as NoSQL, are “horizontally scalable, distributed, and open source”. They offer backups for web servers, content management systems, and document storage just to name a few. This article serves those interested in how relational databases are changing because of non-relational databases and gives the reader enough technical information to research more on the specific impacts. This article is unique that it directly discusses technical details between the two types of databases. Overall, the tone appears to show a realistic sense of where things are heading within databases and that companies need to be ready and flexible to the pending changes ahead.
...text files and spreadsheets, cloud storage will be very beneficial. Using it as backup for these types of files is a major plus. Internet connection speed is not an issue and almost anyone has easy access to the files.
Computers; they are a part of or in millions of homes; they are an intricate part of just about every if not all successful businesses, the government, and the military. Computers have become common place in today’s society and the lives of the people who live in it. They have crossed every national, racial, cultural, educational, and financial barrier, which consequently ushered in the information age. A computer is a programmable electronic device that can store, retrieve and process data, and they come in all shapes, and sizes. They can be used for and in just about anything. As stated before, they are used in just about every aspect of modern society. They are so fundamental to modern society that it would be disastrous to society without them. As stated before, there are many areas in modern society that are run by computers. They play an intricate part of millions of homes in the world. Office workers in business, government and the military may use them to write letters, keep rosters, create budgets, find information, manage projects, communicate with workers, and so on. They are used in education, medicine, music, law enforcement, and unfortunately crime. Because computers have become such a part of the world and how it operates, there is a tremendous responsibility for those who are in control of these computers and the vital information that they carry, to manage and protect them properly. This is management and protection is vital because any loss or damage could be disastrous for the affected entity. For example, a mistake or intentional alteration of a personal credit file could affect ones ability to buy a car or home, or can lead to legal actions against the affected person until the mistake or intentional alteration has been corrected. Therefore, with the advent of computers in the information age, and all of the intentional and unintentional violations against them, comes the need to safeguard them and the information they carry with strong systems and policies of computer security.
Some historians are interested in the preservation of video games, but are wary, as data storage deteriorates rapidly over the years. Floppy disks are particularly challenging as they have a lifespan of only ten to thirty years. More modern video games that use cartridges, such
One of the fundamental and core functions of computers is data storage. The computer has components that retain digital data and record media used for computation. The data stored is in form of bits and bytes. Fast but temporary storage in the computer are often referred to as memory while storage can refer to the storage devices that are not directly accessible, by the Central Processing Unit. Computers use several memory types organized in a storage hierarchy, in the Central Processing Unit. The memory hierarchy consists of CPU registers, SRAM caches, external caches, DRAM, paging systems and virtual memory on the hard drive of the computer. Initially, storage devices were referred to as memory, but nowadays memory refers to a Random Access Memory (RAM) that is a semiconductor storage device. The first manufactured computers used magnetic drums and William tubes for data storage, which had low access rates (Parsons & Oja, 2011, p 76).
