...a consumer you have to appreciate the variety. The American consumer enjoys having choices. However, from the technical perspective the advantages and disadvantages of the numerous types have to be considered. Operating Systems are designed to have different applications pertaining to how they will be used. Many can do the same thing but some are just better than others at what they do. The UNIX operating system allows a number of users to log on at the same time. It is said to be a multitasking/multiprogramming OS, meaning it can run several task at the same time. Also being a multiprocessing system, it can also run several programs at the same time. UNIX is very versatile and it can be set up to support Windows systems and a variety of other systems. It also supports a variety of programming languages, e.g. HTML, C, C++, Java and Java Script, just to name a few. UNIX would be classified as an Enterprise Corporate level OS, and can be run on a mainframe computer (Dean, 2006). UNIX uses a command prompt to interface and communicate with the user and has no GUI. 2. Although Dos is the original foundation for Windows it was a difficult language to use, requiring the user to learn and memorize at least 200 commands. It is also a very limited OS in that it is a single-user, single-task system. Windows is actually a layer over Dos, and is not a true Operating System itself. However, it’s creation was instrumental in building the huge computer consumer market...

...Apple Inc, in 2010. 1. Apple is one of the most known brands in the world. It has been the leading producer of computers, phones and mp3 players for years. Apple had one of the first PC’s built and used for the general public. This has since evolved into a very competitive PC market. The difference between Apple and others is the operating system in which it functions, and the functionality of that operating system. Apple has evolved it’s computers from the big desktop, to the iMac, to smaller laptop style computers that can now weigh a few pounds. They have been on the leading edge of changing technology in order to set the pace for the PC world for all others to mimic. Apples’ PC industry has evolved to that of specilaztion and to be the leader in innovation. Apple products only work with other Apple products, therefore if you have an Apple PC, you’ll need an Apple iPhone or MP3 player if you decide to use those products as well; can’t use a droid or other type of competition. This has developed a culture of Apple only products and having the “latest and greatest” is what is being marketed to the consumer. 2. While Apple’s position on the MP3 and Smart Phone market used to be total dominance, that is no longer the case. Apple was the leader in this technology when it came out with the iPod, then the iPhone. It completely revolutionized these industries. For the first few years, it was the only company that was selling this technology, however others...

...every American family owns at least one personal computer. The personal computer technology has grown greatly improving the personal computer industry. Each year more and more improvements are made. Personal computers today are by far superior to personal computers of 40 years ago. Dimension One The operation of personal computers made today has grown tremendously from personal computers of 40 years ago. In the late 1970s into the 1980s, computers were developed for household use, offering personal productivity, programming and games. Personal computers were made much larger and more expensive systems were aimed for office and small business use. They were difficult to set-up, difficult to operate, and only had 4k bytes of memory. You would need to run several cords, and wires to set-up all the components, it would only operate in basic formats and was costly to upgrade to an expansion memory adapter. It was less expensive to just by the newest model. Dimension Two Nowadays, personal computers are in the workplace, schools, shopping facilities, and almost every household has at least one personal computer in the home. They are a lot more affordable which allows it to be a lot easier to own one. Today’s personal computers are more advanced then they were years ago. They can operate with multiple media for entering programs, for example compact disks, zip disks, and/or a floppy disk. On the other hand, personal computers years ago used cassettes for entering programs...

...Movies have changed over time and there is no doubt about that. Movies used to be very plain with no color or sound. The change in movies today is that we now have sound and color to make movies more vibrant and alive than they used to be. Movies are an evolution. Boring old black and white, soundless movies are a thing of the past! Before our current technology, movies were made with no color. Sound had also not evolved yet. In the passage, “How Have Movies Changed Over Time?” it states “there was a time when “going to the movies” meant watching a moving picture on a large screen without any sound.” Movies of the past, also known as old-fashioned movies, were just pictures put together to make it look like motion, but in reality it was just...

...How Speed of a Computer Is Affected By Different Storage Devices Traci Benge CIS/201 May 7, 2012 Charles Jacks 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...

...How Technology Changes Jazz Music Throughout history, jazz has been a crucial block in the establishment of music. Generations of artists found inspiration in each other’s work, and a variety of collection was thus created. Despite the varying styles in different artists’ work, the core of the music always belonged to the jazz genre. The genre of Jazz has evolved throughout the ages and a lot of that change wouldn’t be possible without the development and integration of new technology. Technological advances within Jazz music have allowed new instruments and computer equipment to emerge in Jazz music. This new knowledge has changed the genre in ways people never could have imagined. Things such as the radio and new recording methods were also apart of this new technology that allowed jazz music to change and improve. The phase of music that we are experiencing more of now is involving computers that allow the musicians to create synthesizers that weren’t possible before this new technology. “MARSALIS: Well, I'm not gonna put that on his head because he can do stuff Hendrix never thought of doing.” What Marsalis is talking about is the musical icon Prince and how you can’t compare him to Jimi Hendrix because technology was so different between their times. Jimi Hendrix came from a time where live music was the main way people could listen to their favorite artist. As the electric microphone made advances in its technology, it changed the development within the recording session...

...Chapter 2 1. How many generations of computer hardware have evolved? What is one characteristic of each generation? There are five generations. First-generation used vacuum tube technology and they are bulky and unreliable. They generated too much heat. It is too hard to program. For the second generation, it used transistors. Compared to first-generation, they are faster, more reliable, and easier to program. Third generation combined integrated circuits. Their characteristic is small and fast. As developing to fourth generation, the computer became smaller by using VLSI circuits. Personal computer appeared. Finally, the computer we use now is fifth generation. It is much faster because of parallel processing CPUs. It spends less power. 2. How many generations of computer software have evolved? What is one characteristic of each generation? There are five generations and it has been listed blow: Generation | Major attribute | First | Machine language | Second | Assembly language | Third | High-level language | Fourth | Fourth-generation language | Fifth | Natural language processing (NLP) | First, the machine language is time consuming. Second, assembly language is much easier to program and higher level. Third, high-level language is more like English. So, it is easier to learn and code. Forth, fourth-generation language also called nonprocedural language. It means that people don’t need to follow the rigorous command syntax to...

...undergone throughout centuries of its existence and development. To a large extent these changes were caused by technological progress: new inventions often transformed the way of people’s lives and respectively, the norms by which societies lived. Airplanes, cars, computers, mobile communication devices, as well as other technological wonders have reformed the way we think and live. But, what is even more curious, technologies have also metamorphisized the way we communicate. Englishmen have a tradition to talk about the weather when they met an unfamiliar (or even a familiar) person. Japanese people have multiple complex ways to start a conversation politely. Many other nations also had their own rules of etiquette; these rules allowed people to enter the communication process smoothly. However, nowadays we can see that etiquette is rather often neglected in favor of the efficiency of communication. The pace of everyday life has increased dramatically compared even to the middle of the 20th century, and today people have to sacrifice courtesy in favor of productiveness and efficiency (IFResearch). Perhaps, from the viewpoint of a person from the 1950s, we would most likely look like rude and straightforward people, as we have become less concerned about our culture of communication, considering it to be archaic. The time we live in is interesting in terms of the existence of at least two levels of language usage; basically, they are the real world and virtual reality (IDFS). The...

Write few lines to describe this diagram. Computer hardware is the physical parts or components of a computer, such as the monitor, mouse, keyboard, computer data storage, hard disk drive (HDD), graphic cards, sound cards, memory, motherboard, and so on. The OS and other software can’t be used without hardware. Operating System is a software program that acts as an interface between the user and the computer. The operating system plays the role of host for all applications running on the equipment (hardware) Application software is a program or group of programs designed for end users. These programs are divided into two classes: system software and application software. Application software resides above system software and includes database programs, word processors, spreadsheets, etc. Application software may be grouped along with system software or published alone.
