It will describe and explain what a system bus is, and why it is needed in the computer system. A summary of the Boolean operators and the use in computers calculations will be included as well. Finally, a short list of various types of computer storage and memory will be included, and a definition of computer storage. Keywords: Neumann, Boolean, Memory, Storage, System, Bus John Von Neumann was born in 1903 in Budapest. He studied mathematics and graduated from the Pázmány Péter University in Budapest with a Ph.D. In 1930 he was invited to the University of Princeton to teach mathematics in the Institute for Advance Study of Princeton. Von Neumann possessed an extraordinary memory, he was a gifted man that made multiple contributions to the math world, and the computer world, but perhaps his biggest contribution is the creation of the Von Neumann Architecture. The Von Neumann architecture stated that a computer was able to have an uncomplicated, established structure, able to execute any calculation when given the proper command. The Model of this architecture is comprised of the following components, the memory, the control unit, the arithmetic logic unit (ALU). The memory was used to store the information from the ALU or processing unit. This...

...Unit 1 Assignment Dan SItkowski 1. Cell phones uses both voice and data networks. It uses data to get information and to also be allowed to access the internet. It also uses voice when you make a call. 2. Land phones use both networks. It uses data for caller ID and to send the information to find out where the call will be going. It also uses voice to transmit back and forth so that you can have a convocation. 3. SMS/Text messaging uses data networks. It only uses data networks because you are sending a message to another person. And in that message you can have files attached to the message as well. 4. Fax machines uses a data network. It uses this network because you put a document or photo threw the machine and it takes the image of that and creates a file. It then takes that file and sends it to another location. Then that location opens and prints or views the file. 5. Pagers use only data networks. It only uses data networks because when you send a file containing only text and then send it to a pager. The pager then takes that file and opens it showing the text for that person to read. 6. VOIP (voice over IP) uses data networks. VOIP uses data networks only because It uses the internet to talk to people instead of the traditional voice network. This allows someone to bypass the phone company. It works by taking the conversation and converts it to a file that is sent to the other location where it is opened. The problem with this is that if the...

...Assignment 1: Computer Memory Hacking Professor Carl Brown CIS 106 Technology continues to evolve exponentially. However these technological advancements continue to pose a threat to both individuals and information resources of companies and governments. There is therefore the need to protect one’s data and information due to the emerging threats and risks. Hacking is where third parties create a backdoor version of a hardware and software so as to manipulate or unlock hidden functionalities on a machine. Most of these hacks are open source and free soft wares. These hacks manipulate the firmware update option on many devices to run and install themselves. Many researchers have found out that breaking into a computer’s encrypted hard drive is very easy with the help of the right tools. A research by Princeton University revealed how low tech hackers access even the most well protected computers (Jordan Robertson 2008). This paper details how encryption was coveted for a long time as a vital shield against hackers, but can be manipulated by altering the operations of the memory chips. This paper outlines just how vulnerable the data we store on our computers and laptops is to possible hacking. Through freezing the Dynamic Random Access Memory (DRAM) chip, which is the most frequently used memory chip in personal gadgets. Freezing DRAM makes it retain data for many hours way after the machine loses its power. This data includes the keys used to unlock encryptions. If the...

...Unit 1 - Assignment 1 - Home Computer Analysis Fortunately my home computer is already running Windows 7 ultimate x64 edition so there isn’t anything for me to upgrade to yet, unless windows 8 gets released soon but even then I won’t probably upgrade. My computer is home built and has an Intel E8400 3.0 Gig Dual Core processor with 4 gigs of DDR3 and 2 Terabytes of hard drive space. I’m also running an NVidia GTX 560 TI overclocked video card and hooked up to a 50 Mbps cable modem. I built this computer a few years ago and I built it for gaming so it’s not top of the line anymore but more than supports any operating system you can throw at it. Let’s suppose I had windows 7 Home Premium and wished to upgrade. Luckily my computer can easily support any version of windows 7 so all I would have to do is run the Windows Anytime Upgrade and upgrade to which version I wished. Since each version is a superset of the higher version you can easily upgrade to higher versions. Also since windows 7 places the entire OS on the hard disk it isn’t an upgrade in the traditional since, it’s just a matter of activating features that are already there. If I had a 32 bit version and wished to go to a 64 bit version I wouldn’t however be able to do an anytime upgrade. When your going from different bit versions you need to do a clean install to install the whole 32 or 64 bit version. This is the only time I would need to do a clean install, if I wanted to go back to x32 for some strange reason...

...Assignment 1: Computer Forensics Overview CIS 417 Computer Forensics Computer forensics is the process of investigating and analyzing techniques to gather and preserve information and evidence from a particular computing device in a way it can be presented in a court of law. The main role of computer analyst is to recover data including photos, files/documents, and e-mails from computer storage devices that were deleted, damaged and otherwise manipulated. The forensics expert’s work on cases involving crimes associated with internet based concerns and the investigations of other potential possibilities on other computer systems that may have been related or involved in the crime to find enough evidence of illegal activities. Computer experts can also use their professional knowledge to protect corporate computers/servers from infiltration, determine how the computer was broken into, and recover lost files in the company. Processes are used to obtain this information and some of the processes are as follows; * Investigation process: Computer forensics investigations will typically be done as part of a crime that allegedly occurred. The first step of the investigation should be to verify that a crime took place. Understand what occurred of the incident, assess the case, and see if the crime leads back to the individual. * System Description: Next step, once you verified the crime did occur, you then begin gathering as much information and data about the specific...

...Computer Structure and Logic Lab 1 12/17/2015 The computer I am working on right now has Windows 7 Installed on it. Windows 7 is not perfect. Some features are underdeveloped. For example when typing the cursor will move through the document. And some annoyances remain intact. But overall, the final version appears to be a worthy replacement to Windows XP. In window 7 you can take the Screen and split it into two. This is a great feature when you are writing a paper and doing research at the same time. To do this just click on the middle of the tab bar and drag left or right, then take your other screen and go the opposite way. In windows 7 you can now pin Icons to the task bar. For example you can pin chrome to your task bar, to do so open chrome, it will appear in the task bar when it does right click on it. Click on pin to task bar, now you have easy access to chrome. Windows 7 started the “Peak”. You can take your mouse and hover your mouse over an icon on the task bar that is active, when you do this a small screen pops up and you can see what is in that tab. Desktop Gadgets can be added to windows 7. You can add the Weather or even a picture slideshow to the desktop, just right click on your desktop and click on gadgets. Double click on the gadget you want and it will appear on your desktop. The desktop I am using has an Intel Core Processor the CPU is running at 3.30 GHz. It has 8 GB of RAM wish it had at least 16.

...Harrison Jackson Excerpt comparing laptop and desktop computers: A laptop and desktop computer differ in both size and functionality. A laptop is much smaller and therefore often more convenient to use. A desktop computer is much larger, and tends to last much longer than a laptop before it needs to be repaired or replaced. A laptop is often a self-contained unit, and no additional parts are needed to run it. Users often have to purchase monitors and other accessories to operate a desktop computer. There is little to no difference in the types of software that can be run on each type of computer. The size is the most noticeable difference between a laptop and desktop computer. A laptop is a single machine with the hard drive, disk drive, monitor, wireless modem, keyboard and mouse contained within it, and it easily folds to be stored in a carrying case. The only additional accessory that is often needed is a power cable with an adapter attached to it. A desktop computer consists of a tower, which is a large rectangular box. The hardware for the computer system is contained in the box. An external monitor, keyboard, mouse and wireless router often need to be attached to a PC in order to fully operate it. The way in which a laptop and desktop computer system are powered is another difference. A laptop runs on a rechargeable battery. The user often has to plug the laptop into a power source in order to recharge the battery. The laptop can only be used until the battery runs...
