How Does Pdf Manage Bitmap Images Information Technology Essay Primary storage is the main area in a computer in which data is stored for quick access, Primary memory storages are also temporary, were as secondary storage is permanent. For example RAM (Random Access Memory) is primary storage so when the computer is switched off or restarted the data that is being stored is wiped from the memory. Retrieved from the Computer Hope Web site: http://www.computerhope.com/jargon/p/primstor.htm. Secondary storage on the other hand has data written to it so the data is permanently stored there. Primary storage is closer to the CPU and is mostly integrated onto the motherboard there it is faster when performing tasks, compared to secondary which is connected through cables. Primary storage is the cache and random access memory is as it is part of the central processing unit, this is the only memory that is directly accessible to the central processing unit. Instructions are stored in the primary storage in which the CPU continuously reads and executes wh en required. Any data that is actively operated on is also stored in the primary storage in a uniform manner. Secondary storage differs from primary storage as it is not directly accessible by the CPU. Secondary storage is the hard drive of a computer in which all the information that needs to be saved is stored there.

In the architecture of computer hardware, systems software networking, 4th edition, 2010 there are 2 definitions of what virtualization is. These are; existing or resulting in essence or effect though not in actual fact, form or name and created, simulated, or carried on by means of a computer or computer network. (Englander, I. (2010). The Architecture of Computer Hardware, Systems Software Networking. Pg 20.) These two explanations mean that virtualization is when you create something on a computer and simulate it. An example of this is virtual pc which is used on windows 7, this allows a person to simulate running an operating system and it will behave exactly as it would if it was a computers own operating system. This virtualization allows people to test programs on virtual versions of operating systems but within another operating system, this allows people to test programs to be able to make sure that their current programs are compatible. Another example of this would also be when using servers. Virtualization allows a server to make virtual servers that run independently so there could be 20 servers but they are all virtual therefore they would only have to be on one or two real servers. This is used to cut costs and to make it easier to manage a server as it is entirely virtual therefore it does not cost anything to run can reach at its potential efficiency. Englander, I. (2010). The Architecture of Computer Hardware, Systems Software Networking (4th ed.).** London, United Kingdom: London University Press.** The inputs to the home cinema system would be the cables that power the system. An input to the television and home cinema system would be the DVD player as that is sending data to the television to show the film on the DVD. Other inputs in the system would be the input from the reliever to the television. This is used so the television receives a signal to provide a picture on the television. The remote also provides and output into which the DVD player and TV would receive an input from the remote to control the components. The user can then decide what they want to happen on the DVD player and the TV for example what channel is on the television or the volume or navigating through a menu on the DVD player. The plug socket is an output which it inputs power to the TV and cinema system. The Television itself would be an output as it is providing the visual part of the system, whilst the speaker components are outputs as they provide the audio. Remote Cloud computing is the method of which data and applications are stored and accessed over the World Wide Web. Cloud Computing Defined. (2010). Cloud Computing Defined. Retrieved from the Cloud Computing Defined site: http://www.cloudcomputingdefined.com/. The idea behind cloud computing is that your data is stored and backed up on a computer somewhere in the world that can be accessed at any time. But you will not know where your data is being stored. This means that the users are unaware and do not know of any of the details of the applications use, for example where the hardware that is being used to store it is located. A PDF is treated as a file format so with the right software any person can look at the file. PDF also contains its own bitmap formats, object image formats and text formats which are all optimized for creating and presenting pages quickly. So because a PDF has its own formats so when a program opens it will display the file in the way that any monitor can view it, including printers as a PDF is a standard therefore each printer and operating system must be accustomed to that standard therefore allowing it to be seen consistently. Describe the format for storing, laying out, and managing the objects on a page. Explain the advantages to the use of this format over other formats, such as that used by HTML. The advantage of using PDF format over other formats such as HTML for storing, laying out and managing objects on a page would be that there are many algorithms which are used for compression which enable a faster and smoother file transfer, Therefore the application is much more flexible The advantage of using the PDF format over other formats for storing, laying out and managing objects on a page would be that they have many algorithms for compression which enables smooth file transfer. The application therefore is more flexible. Due to the compression techniques it is also more portable due to the smaller sizes that PDFs can have compared with something like HTML. Jenny Hamper.

Difference Between PDF Vs HTML Retrieved from ezinearticles site: http://ezinearticles.com/?Difference-Between-PDF-Vs-HTMLid=3972193 A font in PDF is a description of a digital typeface which is a set of one or more fonts,. These descriptions can describe the characteristics of a typeface, but can also include an embedded font file. Font files that are embedded are based on commonly used digital font formats. A PDF will use character codes that are within text strings to map the current font using an encoding. There are predefined encodings that exist in a PDF which are universal and will work on any platform. A PDF can specify a predefined encoding to use which can be the fonts built in encoding. Any file which contains fonts are also collected when a document is saved as a PDF so all of the available fonts the user has are stored on a PDF which makes it easy for a PDF to show that particular font or show a font that is in the same family so there is some resemblance to the original font. How does PDF manage bitmap images? Object images? Describe at least three major limitations that PDF places on the end-user of a PDF document. One major limitation of PDF is that it cannot be edited once a file has been converted into a PDF then it cannot be edited as it is an image of a document. What are the criteria that define a Von Neumann architecture? How does the example of entering and adding two numbers illustrate each of the criteria? If the memory register for a computer is 32 bits wide then this computer can support 4gb of memory. This is because the memory can access 32 locations and each location has either a 0 or a 1 stored meaning there are 2 states at which the 32 bits can be accessed. Therefore 232 = (4 294 967 296) meaning that there are 4.3GB of memory available as there are that many different combinations. This means that a system with a 32 bit wide system can only have a maximum of 4GB as there is only a maximum of 4 294 967 296 different memory combinations. Volatile memory is computer memory that can only maintain memory if it is being powered by the computer. Non-volatile memory is the opposite of volatile memory in which it is computer memory that can retain information when it is not being powered. RAM would be an example of volatile memory because when a computer is turned off any information that hasnt been saved and is on the RAM is deleted. A hard drive (ROM) is non-volatile memory because when there is no power to the ROM the data that is being stored is kept even when there is no power as the data is written onto the OM so it is kept.

Book Report on Freedomnomics by John Lott Essay

The effective management of the economic aspect of the country is always valuable and necessary to guarantee the financial stability of the nation and its people. As such, it is empirically significant that the economy is free from any manifestation of restriction for it to efficiently operate. Such condition is the underlying principle and practice behind what is called a free market. Economic freedom is attributed to the flexibility and most importantly, immunity of the economic field from limitations. In carrying-out such ideal situation, the reality that free economy works most to the advantages of both the people and nation is established. With such clear indications, it is therefore essential that the concept of free market is supported because it definitely works best for the population and the country in general. The said main thesis concerning the principle and practices of free market was what efficiently exemplified by the book â€Å"Freedomnomics† written by Economist and acclaimed author John Lott. In the said book, Lott (2007) opened the minds and hearts of the public about the necessity of a free market condition due to its many relevant advantages both for the people and societies. In doing so, the book not only provided its readers with a glimpse about the nature and components of free market but also allowed the public to realize its benefits. To support the book’s thesis, Lott based his premise from several case studies which all pointed to the significance of free market thus he called for and emphasized the need for economic freedom (Lott, 2007). In supporting his main theory on free market, Lott stressed major points that showed how free market or liberated economy paved the way for the eventual successful handling of the other aspects of the society such as the political system and the structure of the criminal justice as well as even the ethical or moral features of a country like the United States. It is in this position therefore that the book ultimately succeeded because it was able to make way for the public’s recognition that free market encompassed not only the economic aspect of the country but its other social components as well. Hence, there is indeed a need to adhere to and uphold the free market principle in order to achieve the nation’s improvement. The Free Market Premise In â€Å"Freedomnomics,† Lott effectively explored on the premise of free market-its nature, components, practices and most of all, its significance to people and the society. Citing the notion imparted by Adam Smith, the author outrightly presented that from such principle, where a nation’s economy just like the U. S. is free from any form of restriction, â€Å"the free market works† (Lott, 2007, p. 1). Taking into consideration the results of a number of economic-related case studies which he did on his whole career, the relevance of the principle of free market was highlighted by the author through the book. Additionally, the book’s point of view evolved around and was analyzed according to the philosophy that a restricted kind of economy, such as the one manifested by communism, is undeniably harmful. This is supposedly because of the fact that economic restrictions also result to portrayals of limitation that detriment other aspects of the society (Lott, 2007). As a support to his free market theory, Lott gave the public major points that all signified the benefits of such concept. In doing so, it became apparent for the book to prove the harms when the economy is subjected to any kind of restriction. The points that supported the free market perspective were bravely presented by the book like its opposition to the book â€Å"Freakonomics† by Steve Levitt and Stephen Dubner. The Lott book stressed the advantages to be derived from free market or economic freedom when it challenged its counterpart’s philosophy that the American economy is a swindling business because both the corporations and their people are cheating the public (Lott, 2007). In correcting the wrong notion brought about by â€Å"Freakonomics,† Lott’s â€Å"Freedomnomics,† in turn, clarified that the American economy, due to its free market principle, truly operates according to rules. This is because the field, as represented by many corporations, exerts earnest efforts â€Å"to make a profit by supplying people with something they want† (Lott, 2007, p. 3). It is in this condition that the effective operation of free market is exhibited due to its remarkable advantage of encouraging the economy and people behind it to act honestly and accordingly (Lott, 2007). The book further perceived that treating the public honestly made the free economy maintain its good reputation. Notwithstanding the supposed penalties and legal liabilities, the best motivation for the economy and corporations is to preserve their honesty and honor. Most importantly, it is not only the economy which benefited from free market as such principle likewise paved the way for proper operation of the other aspects of the society or the the sincere actions of other members of the society such as political leaders, professionals, members of the criminal justice system, all of which ensured adherence to moral standards. As a proof, Lott cited his experiences which confirmed that economy, politics and religion were connected. This was recorded by his opinion-editorial materials in the July 13, 1986 issues of the Great Falls Tribune and the Montana Standard (Lott, 2007, p. 7). Conclusion Regardless of the disputes against the free market principle, â€Å"Freedomnomics† effectively justified such and even emphasized its undisputed benefits which made the book commendable. Ultimately, it is only through continued observance of free market or liberated economy that Lott prescribed the country to become better and stable. Reference Lott, J. R. (2007).
