Introduction In this era, people own various types of electronics which contain hard disk drives. Among these HDD (Hard Disk Drive) industries, Seagate is one of the worldwide leaders in manufacturing and marketing of hard disk drives. Seagate’s corporate office is located in Scotts Valley, California and employs nearly 52,000 people around the world. As one of employees in Seagate Company, I will explain in detail the nature of the HDD industry and its products. 2. History of HDD Industry Behind the HDD (Hard Disk Drive) industry is an interesting and challenging history. In 24 years it progressed from a monstrosity with fifty two-foot diameter disks holding five Mbytes of data to today's drives measuring 3.5 inches wide and holding 2 Tera-Bytes. The HDD market has expanded into consumer applications such as camcorders, cell phones, audio players, video players, video recorders, personal assistants and video game consoles. Before the disk drive was created, there were magnetic drums. In the 1950s, Engineering Research Associates of Minneapolis built the first commercial magnetic drum storage unit for the U.S. Navy, called ERA 110, which could store up to a million bits of data. In 1956, IBM invented the first computer disk storage, the 305 RAMAC (Random Access Method of Accounting and...

...Hard drives store data in the magnetic polarization of small patches of the surface coating on a (normally) metal disk. The maximum areal density is defined by the size of the magnetic particles in the surface, as well as the size of the "head" used to read and write the data. The areal density of disk storage devices has increased dramatically since IBM introduced the RAMAC, the first hard disk in 1956. RAMAC had an areal density of 2,000 bit/in². Commercial hard drives in 2005 typically offer densities between 100 and 150 Gbit/in², an increase of about 75 million times over the RAMAC. In 2005 Toshiba introduced a new hard drive using perpendicular recording, which features a density of 179 Gbit/in².[1] Toshiba's experimental systems have demonstrated 277 Gbit/in², and in 2006 Seagate Technology demonstrated a drive with a 421 Gbit/in² density.[2] It is expected that perpendicular recording technology can scale to about 1 Tbit/in² at its maximum. [3] Compact Discs (CDs), another common storage media of the early 2000s, stores data in small pits in plastic surface that is then covered with a thin layer of reflective metal. The standard defines pits that are 0.83 micrometers long and 0.5 micrometers wide, arranged in tracks spaced 1.6 micrometers apart, offering a density of about 0.90 Gbit/in². DVD disks are essentially a "product improved" CD, using more of the disk surface, smaller pits (0.64 micrometers), and tighter tracks (0.74 micrometers), offering a density of about...

...replaced. These three computers all have internal hard disks with 50GB of storage capacity or less, have processors running at speeds of less than 2GHz, have less than 2GB of RAM, have CD drives, and n more than 2 USB ports. I want each to have at least 100GB of storage capacity, run at speeds of more than 2GHz, have at least 3GB of RAM, have at least one of the laptops with a DVD drive, and at least 3 USB ports each. I would also like our new computers to all have a Windows 7 operating system and to have some sort of built-in memory card reader. There have been several instances where it would have been helpful if these clerical workers were onsite with clients so I recommend replacing these three desktops with laptops. These three laptops will still be connected to our local network but done so wirelessly. I have done some research and here are my purchase recommendations: • Windows 7 Home Premium Operating System • 2.4GHz Intel i3 Dual-Core CPU • 6GB of RAM • 500GB Hard Drive • 8x DVDRW Drive • N 2230 WLAN • 3 USB 2.0 Ports • 8-in-1 Memory Card Reader 1 – Dell Inspiron 15R with 15.6” screen - $469.99 - This laptop meets all of the require criteria. Its specifications are considered fairly basic these days but I think the price can’t be beat. 2 – HP ProBook 4540x with 15.6” Screen - $549.99 • Windows 7 Professional Operating System • 2.4GHz Intel i3 Dual-Core CPU • 8 GB of RAM • 750GB Hard Drive • SuperMulti DVDRW Drive • Gigabit Wireless LAN Adapter • 2 USB 2...

...Kevin Wingate November 10, 2014 NT1110 – Computer Structure and Logic Research Project – Network Attached Storage A Network Attached Storage (NAS) device is a device connected to a network of two or more computer with the purposes of providing “community storage” of files and other data. As our society moves closer towards greater mobility the need to have mobile storage has increased. There are many types of storage devices, with various advantages and disadvantages to each of them; including Direct Attached Storage (DAS) and Network Attached Storage Devices. NAS devices are useful if all the computers on the network need access to the same files, DAS can only be accessed by the computer they are attached to (unless the computer grants access to another user. Most NAS devices contain multiple hard drives, which are connected by an internal server. There are many features of NAS devices. The speed of the network is dependent on the service available to the network and the number of users on the network. The capacity range of the network is depend on the hard drives contained in the device and the way it is setup. As with most servers or combination of two or more hard drives (Redundant Array of Independent Disks) RAID can be set up to maximize the use of the server and to protect the data. Also most NAS devices have software, which can be installed on client computers which allows the user to manage the device. The device has an IP address which also allows you...

...the power needed to run all the computer’s components and also provides all the power cables I will need to supply the expansion components that will be installed later in this build. Different devices in the computer and on the motherboard all need different levels of power so to speak so the power supply also reduces and converts the raw electricity into the exact amounts needed by each component by using capacitors and resistors etc. built within the power supply itself. The Case is also very important in this build as I will need a case that can support the motherboard form factor and power supply design I have chosen. The case must also have the needed expansion slots built in and the correct amount of expansion bays for my optical drives. For the power supply I have chosen the OCZ ModXStream Pro 700W Modular High Performance Power Supply, this power supply has everything I need to power all the devices and expansions I will be adding to the computer its specifications are as follow: “Model number OCZ700MXSP, Type ATX12V V2.2 / EPS12V, Maximum Power 700W, 1 x 135mm Fan, Main Connector 20+4Pin, PCI-Express Connector 1 x 6-Pin, 1 x 6+2-Pin, SATA Power Connector x6, SLI Certified, CrossFire Ready, Input Voltage 100 - 240 V, Input Frequency Range 50/60 Hz, Dimensions 5.9" x 3.4" x 6.3" Features, 1 x Main connector (20+4Pin), 1 x 12V(P4) 1 x 12V(8Pin )4 x Peripheral 6 x SATA2 x Floppy 2 x PCI-E(Cooler2011).” I have chosen this specific power supply for a few reasons one of...

What correct turns and what wrong turns did they make? d. What do you think are the root causes of the failure of the Kittyhawk program? e. Is there any way HP could have avoided its fate by addressing these root causes? In June 1992, Hewlett-Packard (referred to HP hereafter) introduced smallest hard disk drive in the world named as the Kittyhawk. It was the first ever commercially produced hard drive in a 1.3 inch form factor. The idea was conceptualized in early 1991 by HP’s management when it was eagerly trying to explore strategies for transforming their Disk Memory Division (DMD) as a market leader. Kittyhawk project team was led by Rick Seymour under the supervision of Bruce Spenner. From the inception of Kittyhawk, Spenner had been keen that the new technologies that had an enormous potential to cause new-market disruptions. He intended to create a disk drive feasible with any product that had microprocessor. Kittyhawk offered a smaller, light weight and highly reliable solution for customers as the trade-off for reduced performance. But believing they had a chance to enter new markets, HP channelized their organization efforts on these new technologies. Some people from top management of HP got involved, creating separate, financially autonomous divisions and providing limitless access to necessary...

...an entire home network, but it also comes down to what the needs of everyone in the household are. If you have gamers or those with workstations, then you’ll definitely need to take into consideration that you’ll need better than average hardware. But some family members may only need a simple notebook, tablet, or even their smart phone to connect to the internet. Most people enjoy streaming applications such as Hulu, Netflix, and Crunchyroll. Before you start, you need to figure out what the network will be used for and tailor it to the needs of everyone who uses it. For this example, I’m going to use my own family’s network. It’s a simple network that will most likely be sufficient for the average family. Starting out, you need to research the internet service providers (ISPs) in your area. These can range from large companies to small local companies. If you do a lot of video streaming and gaming, then you’ll want a fairly good connection speed. I’d recommend going with at least 20Mbps download and 5Mbps upload. The company we use is a local company called Forsyth CableNet. Hardware: You’re ISP can provide you with rental modems. I believe this to be a great option because modems can be costly to replace if they’re damaged. It usually means adding a little extra to your monthly bill, but the ISP will be responsible for replacing it if damaged. Also, they’ll most likely provide the coaxial cables and Cat5 cables necessary for connecting to the modem. For our network,...

...into information technology David Carlson CIS/319 May 1, 2011 Bob Sanders How Computer Technology Ties into Information Technology This paper will show how computer systems are an integral part of information technology. We will look at: the best methods of data input for given situations, in given situations what are the best methods of output, the different types of storage and their optimal use, and how certain components affect computer speed. Accuracy of Data Input is Important Now we will look at five different scenarios and what would be the best way to input data and why. Printed questionnaires or surveys are often part of research studies so the method used to input their data into the system needs to be as accurate as can be. Human data-entry devices (HDED) would not be a very reliable form of data-entry because most research studies put out hundreds if not thousands of surveys and for people to try to input all that data accurately would be almost impossible. Since almost all surveys are multiple choice the best choice for the input method is the optical mark reader. The optical mark reader is a source-data automation input device (SDAID) that scans the survey detecting marks on the answer grid. Telephone surveys are another changing part of society, in the past phone surveys were handles by multitudes of phone operators asking questions and typing the responses into the computer. Times have changed and companies are seeing that the time of the human phone operator...

...I’m not sure if this means I am a bad person, but the first thing I thought of in regards to disposing of old computers, was making sure all of your personal data was wiped, not about recycling. I think one of the most important things you can do when getting ready to dispose of a computer is to make sure you properly delete all personal information that may be left over on your hard drive. People have computers that “die” or are not able to work anymore, so they might think just throwing them away is safe. But someone who has even a little knowledge about computers can easily open up your laptop or desktop and take out your hard drive. Hooked up to another computer, it would be very easy for them to scan it for personal information. t’s odd to think about replacing a motherboard, because I have actually considered this on personal computers I have owned in the past. But when I talk with some friends who are not as comfortable with changing out hardware, they often times feel so lost because they are not really sure what to look for when purchasing components, such as a motherboard. I think the first thing you need to decide on when shopping for a motherboard, is what is it going to be used for? Are you using your computer for just checking emails and Facebook? Or will you be doing some heavy processing, such as gaming or video editing? I would assume that someone who is actually shopping for a motherboard is doing so...

...Research Paper – Cloud Computing Cloud computing in its simplest terms, means storing and accessing data and programs over the internet instead of on a computer’s hard drive (http://www.pcmag.com/article2/0,2817,2372163,00.asp). The cloud is a metaphor for the internet, and the name cloud computing was inspired by the cloud symbol that’s often used to represent the internet in flowcharts and diagrams (http://www.searchcloudcomputing.techtarget.com/definition/cloud-computing). Essentially, this eliminates the need for large storage hard drives. Computers now come with storage sizes between 320 GB-1tb which seems like a lot, but as time goes by and the amount of programs and files you gather, that storage space decreases. Then, before you know it, your computer has only a few gigabytes of storage left, and runs slowly due to too much stored data. When data is written to the computer’s hard drive, it is stored on any available spot on the hard drive. Large programs like video games that take up massive amounts of gigabytes, are written all over the hard drive, hence causing the software to load slowly and even glitch sometimes. People upgrade the size of their computer’s storage all the time, whether it is via external hard drives, the addition of multiple hard drives, or the replacement of the hard drive with a new one. Although prices have dropped for storage devices, it is still a decent amount of money spent and consumes time. With cloud computing, all of this can be eliminated...

SNHUConsulting, a leader in information technology, has been retained to implement information technology on the expansion and to connect the network in the new facility to the main network that is located at their headquarters. I have been asked to make recommendations on the computer hardware components for the expansion. Widget Wonders has provided SNHUConsulting with the pertinent information about each of the departments in order to implement the best hardware. The following is the information provided by Widget Wonders and the recommendations of SNHUConsulting. The sales department consists of 50 employees which require mobility to access company resources while visiting customers and presenting at sales meetings and conferences. My recommendation for this department is notebooks, smartphones, and tablets as they would work best for mobility when visiting with customers as they are small and lightweight computers that can easily be carried around, along with docking stations to charge the devices. For those times when the sales team is presenting to larger groups I would recommend a digital projector that can be plugged into the notebook or tablet, portable speakers, and laser pointers. They should also have a supply of USB 3.0 flash drives for a convenient way to store their...
