...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 precision...

...“The Virtual PC Build” When building a performance PC the first step is to carefully pick the power supply and case it is of upmost importance in a build. It is the very foundation of the computer itself. Without these components you cannot have a functional PC. The Power Supply is very important itself as it delivers 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...

...Computer Information Systems Paper Charles E. Jones Jr. CIS/319 Version 8 April 29, 2012 Ike Shia Abstract This paper is to focus on the accuracy, convenience, different types of storage methods, and the roles they play as far as the speed of the systems. Throughout the paper it discusses the best input and output methods for various hardware and software. Accuracy of Data Accuracy of data input is important. What method of data input would be best for each of the following situations and why: As far for printed questionnaires the best method for data input would be a keyboard, because it permits one to produce the required test that formulates the questionnaires. The best method for a telephone survey would be voice recognition and recording system because a voice input device can be programmed to distinguish and record answers spoken into the receiver allowing it to all be computed. Bank checks would best be used in a scanning method that recognizes bar codes. To be more specific a magnetic scanning input device would be the exact system to use. This system reads the numbers at the bottom of the checks and will mechanically make modifications to the correct accounts. It will input the codes in a system will magnetize the information at the bottom of the check for simple interpretation. For retail tags the best data input for would be a bar code scanner as well. This specific scanner is called an optical scanning input device. By using a bar code scanner it...

...Computer-delivered electronic system that allows the user to control, combine, and manipulate different types of media, such as text, audio, video, graphic and animation. The most common multimedia machine consists of a personal computer with a sound card, modem, digital speaker unit, and CD-ROM. Long time as the future revolution in computing, multimedia applications were, until the mid-90s, uncommon due to the expensive hardware required. With increases in performance and decreases in price, however, multimedia is now commonplace. Nearly all PCs are capable of displaying video, though the resolution available depends on the power of the computer's video adapter and CPU. One of the multimedia elements is audio. Audio include music, speech ,or any other sound. Audio and digital music are different from other multimedia elements. This is because the audio and digital music is not related to visual .Audio cannot be seen but can only be heard with the ears only. Computer will result in vibration of air through the speakers or sound box, while our ears detect vibrations in the air. As the sound wave moves away from the vibrating object, the individual molecules do not advance with the wave, they vibrate at what is termed their average resting place until their motion still or they are set in motion are the component that make up a sound wave, frequency, amplitude, velocity, wavelenght, and phrase. Before the continuous wave analog audio can be stored in a computer...

...market was failing to recognize the value of Seagate’s stake in VERITAS, as evident from a 200% increase in VERITAS stock versus only a 25% increase in Seagate’s stock. The board felt that the market was incredibly under pricing Seagate’s stock. After two failed attempts to increase Seagate’s stock price and unlock its value from VERITAS, the company turned to Morgan Stanley for help. In early November of 1999, Morgan Stanley arranged a meeting between Seagate executives and representatives of Silver Lake Partners. After several months of discussion, Silver Lake delivered a proposal and potential solution to Seagate’s problem. This proposal involved a complicated two-step transaction. The first step would involve Seagate selling off its disk drive business, including about $765 million in cash, to a newly-formed company controlled by Silver Lake. The purchase would be financed through a LBO in which Silver Lake and other private equity investors would provide a portion of the selling price through equity, and the rest would be financed through debt The second step, would involve merging the remaining Seagate shell corporation with VERITAS through a tax-free stock swap. Each share of Seagate stock outstanding would be exchanged for a combination of cash and VERITAS shares. VERITAS would then acquire the Seagate shell corporation and its 128 million shares of VERITAS stock. In exchange, Seagate would receive 109 million new VERITAS shares. No...

...Unit 8 Analysis 1: System Performance Disk fragmentation is what causes low performance and other issues. It takes memory computer sources to handle large files like video clips, music files, graphics, etc. Thus, even a system with lots of RAM and a high-end processor can have performance issues. When you format a hard disk, the formatting process divides the disk into sectors, each of which contains space for of data in bytes. The file system then combines groups of sectors into the smallest unit of space available which are known as clusters. Process load and the number of running processes affect system performance. The CPU and the memory are used up by every process running on the computer. The Task Manager is a very good indicator that shows when a process is taking too much of the CPU. It also gives the user the ability to monitor and control the running processes that are affecting the system. With the use of the Task Manager the user can end a process that is taking too many resources. In addition to ending a process, Task Manager also allows users to end a process tree killing all threads associated with the selected process, set a process's priority to reduce or increase its CPU consumption. Adding more motherboard RAM improves virtual memory performance because the OS will use the hard drive as a "swap file" or virtual memory if the computer runs out of RAM. Hard Drives are slower than RAM so you must have enough memory. Today, with a computer and a modern OS, you...

...the first computer was made in the late fifties, technology has developed extremely. Computers which took the place of a living-room then, are now being made in credit card- formats. More and more areas are being taken over by the computer. As computers are capable of handling large amounts of data in a very short time, they are well suited for word-processing. I guess that it won't be long till all the paper-archives are replaced by magnetic tapes and diskettes. A diskette can contain much more data than a written page, and it takes less place! It is possible to get the Norwegian telephone book on just one diskette. In near future, a new area will be taken over by computers, namely maps. Different routes are stored on one single compact-disk. Imagine, simply insert the CD into the CD-driver in your car, and tell the computer where to go. The rest will be done automatically. This will be a safer, faster, and more comfortable way to travel. Another new area, called "virtual reality" is currently being tested. This is a way to simulate reality on a monitor. in order to feel this so-called reality you have to wear special electronic glasses and an electronic suit. Fastened to the suit are sensors, which send information to the main computer. This computer works with the data and displays them on the electronic spectacles. This is a technique which use three-dimensional views, therefore the scenery seems incredibly realistic. If you want to be a boxer, simply change the scenery...
