Abstract Today’s computers have different ways to store data. Some examples of these ways are devices as the hard disk (aka magnetic disk), floppy disk, RAM, CD ROM, tape, and the flash (aka jump drive, USB memory stick, and thumb drive). Storage devices come in two different sources; primary or secondary. Each of these devices causes the computer to process data at different speeds. This paper will show how each of these devices store data and how they affect the speed of the computer.

How Speed of a Computer Is Affected By Different Storage Devices The hard disk of a computer is a secondary type of storage. It can be either an external or internal source of storage for a computer. It is primarily to store a mass amount of data. The data remains stored on the hard disk indefinitely until permanently deleted. The hard disk stores the operating systems and application instructions. Without the hard disk the computer would not know how to open any of its operating systems or any of the other applications for the user. In this RAM (Random Access Memory) works with the hard disk. RAM is part of the primary storage; it contains a software program with small amounts of data for processing. When the computer boots up, it loads the whole program from the hard disk through RAM. Its storage capabilities get larger the farther away it is from the CPU. Saved data gets written onto the hard disk because RAM does not retain any data once the computer turns off. The computer needs to have a balance between the hard disk and RAM for the speed of the computer to be efficient. To avoid a sluggish system the computer should have at least twice as much hard disk space compared to the amount of RAM installed (Dunn & Li-Ron, 1996).…...

Computer Storage

...COMPUTER STORAGE The device, which is used to store data, is called computer storage. We can divide computer storage into following categories. Computer Storage Permanent Secondary Temporary ROM Optical Disk Magnetic Disk Magnetic Tape RAM Cache C.D DVD H.D F.D ZIP Secondary Storage It is not possible to store large amount of data for future use in primary memory of computer because its size is small and it cannot store data on permanent basis. So it is necessary to use some extra media to store large amount of data. That kind of memory is called secondary storage, auxiliary storage, additional storage, external storage or semi-permanent storage. This memory is cheaper that primary memory due to different storage mechanism. Its speed is also slower than RAM. There are two types of secondary memory. Sequential Access Storage: Sequential Access Memory is one in which data is retrieved is in the same sequence in which it is stored. Direct/Random Access Storage: Direct Access Storage is one in which data is retrieved directly/randomly without any sequence. MAGNETIC TAPE Magnetic tape is one of the oldest & popular devices used for storing data permanently. As its name suggest, this device stores information on a magnetic tape that is made of plastic (Mylar) that is the form of magnetic spots. Size The tape ribbon itself is stored in reels of 50 to 2400 feet or small cartridge or cassette. Quality It is similar to the tape used on......

Secondary Storage Devices

...Access Methods of Secondary Storage Devices Secondary Storage Device is storage medium which is used to store large amount of data permanently until it is changed by user. Though it stores information, it cannot be accessed directly by the CPU. The data stored in Secondary Storage Device can be accessed depending upon how it is stored on the device. Mainly there are two methods of accessing data from the Secondary Storage Device. 1) Sequential Access Method 2) Direct Access Method Sequential Access Method – This means the computer system must search the storage device from the beginning until the desired data is found. The most common sequential access device is magnetic tape where data is stored and processed sequentially. For example, a tape contains information regarding students of a school, to look student’s number 100’s information, the computer will have to start with student number 1 and then go pass 2, 3, 4 and so on until it comes to 100. This method is quite simple than other methods, but it is very slow (more time for searching data) & very suitable for bills & payroll applications. Direct Access Method – This is also known as random access, it means the computer can go directly to the location where the data is stored that the user wants. The most common direct access devices are magnetic disc & optical disc. In these devices, the data is stored as sequentially numbered blocks. Thus one can access block 12, then block 78, then block 5......

It280 Week 8 Mass Storage Devices

...Dear Management, I am writing this letter to inform you of the advantages of using external mass storage versus DVD-ROM dual layer drives. First point external mass storage devices such as external hard drives allow more data to be stored onto one medium versus a DVD-ROM. External hard drives come in all sizes from 128GB drives to 3TB in size, while the DVD-ROM dual layer discs max storage capacity is only 8.5GB. Another reason to go with a mass storage device would be for ease of access to data, with DVD-ROM’s one would have to physically search for different media and figure out what data is needed which is time consuming and tedious. On the other hand, with a mass storage device such as an external hard drive one could simply browse or do a quick search on the device and within minutes locate the information or data needed. External mass storage is the future, storage mediums such as CD’s and DVD’s are becoming outdated, technologies such as USB flash drives, SD cards, and external hard drives to name a few have been taking over the market. A factor to consider for justifying the use of mass storage versus DVD-ROM’s is data storage and retention. With DVD-ROM disc with time, they may get scratch unintentionally over time, and the material will deteriorate depending on storage conditions, external hard drives on the other hand are less prone to these types of faults and can last for many years. Another advantage of using external hard drives would be data transfer...

How Technology Has Affected Our Lives

...How Technology has Affected Our Lives Technology has certainly changed the lives of many people in today’s world. According to several reviews, as well as several books written by Nicholas Carr tend to point us in the direction of the technology not being such a good thing. While there are many forms of technology that are used for many different things such as: digital TV, social networking, cellular phones, notebooks, laptops, personal computers and the list goes on are they taking us away from the realities of life? Many sources or authors have their versions of how the different technology has made improvements in our lives; as well as how they are making us think and do a lot less than we used to. The internet makes getting information on any subject so easy for us that sometimes we tend not to do the work, or research that is needed to fully understand what we are doing; instead we follow the instructions and if we need it again we go through the same process without ever learning how to complete the task. This is just the beginning of how technology changes our lives and perhaps we get things done, but are we really learning? This is the question that we hope to answer along the way. There are many ways in which technology has in fact changed lives; the first concern that will be addressed is the way in which technology mainly electronic media has caused changes to occur. When we think of electronic media for this purpose we will focus on television,......

Punch cards Early computers often used punch cards for input both of programs and data. Punch cards were in common use until the mid-1970s. It should be noted that the use of punch cards predates computers. They were used as early as 1725 in the textile industry (for controlling mechanized textile looms). Above: Card from a Fortran program: Z(1) = Y + W(1) Above left: Punch card reader. Above right: Punch card writer. Punched tape Same as with punch cards, punched tape was originally pioneered by the textile industry for use with mechanized looms. For computers, punch tape could be used for data input but also as a medium to output data. Each row on the tape represented one character. Above: 8-level punch tape (8 holes per row). Magnetic drum memory Invented all the way back in 1932 (in Austria), it was widely used in the 1950s and 60s as the main working memory of computers.

Different Computer Users Today Lavon Hawkins Analyzing 6 different types of computer users and the needs of their profession. Abstract  Most computer users fit into one of these basic categories. The Internet & Email user, home users, small or home business, computer graphics, and gaming users. Based upon the profession, and the needs within said profession, would determine what is needed to perform daily duties Different Types of Computer Users    I would identify the “stay at home” Mom or Dad as the more basic user. Basically he or she would be a basic internet user. Most of the time just for checking his or her email, processing letters, tracking bills and finances. It may also be used for saving photos or listening to music. Browsing web sites like Facebook, MySpace or maybe a dating website (if he or she is single) may also be an option. Processing speeds probably wouldn’t be a concern because of the low priority for internet purposes. Because of this, I believe an AMD processor computer would be better because less space would be needed and it wouldn’t require much hard drive space and/or RAM.      Home business owners may need more reliability.

How Electricity Prices Are Affected by Inflation

...How Electricity Prices are affected by Inflation (A case study of Bangladesh) Introduction: Electricity prices are affected by inflation to increase day by day. Electricity price high is one of the greatest parts of our economic condition in our country. Raising electricity prices tend affect to overall consumer price index. If electricity price high it is also affected our household increase, companies usually chose to pass a those costs to their customers. Inflation: In simple language, inflation means rising prices and it shows the increase in cost of living. In economics, inflation is explained as rise in the general level of prices of goods and services in an economy over a period of time. With the rise in price levels a unit of currency will buy fewer goods and services. As a result, the purchasing power of money will be reduced with inflation. In other words the real value of money will be lost day by day along with inflation. Inflation is measured by the Rate of Inflation or Inflation Rate which is the percentage change in a general price index calculated as an annualized figure. Inflation Negative effects: • Decrease in the real value of money. • Unpredictable inflation rates. • Discourage investment and savings. • Add inefficiencies in the market. • Difficulties with budget and long-term planning for companies. • Hidden tax increase. • Demand of rapid wage increase • Causes Hyperinflations.

How Computer Technology Ties Into Information Technology

...How computer technology ties 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......

How the Internet Has Affected Society

...decisive technology of the Information Age, as the electrical engine was the vector of technological transformation of the Industrial Age. This global network of computer networks, largely based nowadays on platforms of wireless communication, provides ubiquitous capacity of multimodal, interactive communication in chosen time, transcending space. The Internet is not really a new technology: its ancestor, the Arpanet, was fist deployed in 1969 (Abbate 1999). But it was in the 1990s when it was privatized and released from the control of the U.S. Department of Commerce that it diffused around the world at extraordinary speed: in 1996 the first survey of Internet users counted about 40 million; in 2013 they are over 2.5 billion, with China accounting for the largest number of Internet users. Furthermore, for some time the spread of the Internet was limited by the difficulty to lay out land-based telecommunications infrastructure in the emerging countries. This has changed with the explosion of wireless communication in the early twenty-fist century. Indeed, in 1991, there were about 16 million subscribers of wireless devices in the world, in 2013 they are close to 7 billion (in a planet of 7.7 billion human beings). Counting on the family and village uses of mobile phones, and taking into consideration the limited use of these devices among children under five years of age, we can say that humankind is now almost entirely connected, albeit with great levels of inequality in the......

How Computers Have Evolved

...How Computers Have Evolved Computers have drastically changed throughout the years. Comparing the first computers to computers of today would probably give you a good laugh. When computers were invented, the average person didn't use them. In fact, the average person would have had a very difficult time understanding how one operates. When computers were first invented you had to know very complex commands to operate them. The internet wasn't what it is today. Most of the information found on the internet today like shopping, games, and facebook wasn't around when it first came out. In the following paragraphs I will explain how computers have evolved. User interfaces have made some of the biggest changes. The very first computers were command driven. You had to know commands in order to do what you wanted it to. That is no longer true today. Today's computers use a graphical user interface called a GUI. You simply point and click. This makes it so people who don't know much about the way a computer operates can still use it. Using DOS commands was a very difficult process to learn. The invention of GUI interfaces such as Windows and Mac OS has made DOS commands obsolete. The size of computers have changed greatly over the years. Some bigger computer systems still exist but most computers are smaller and easier to handle. What once filled a room is now found in small cell phones. This is made possible by the discovery of new technologies and higher......
