A)
Microprocessor: The chip that holds the Central Processing Unit (CPU). The CPU is the brain on the computer. The microprocessor is also responsible for containing the necessary hardware such as pins, or contacts to connect itself to the motherboard or socket/slot/etc.

Hardware: Anything physical that can be touched in regards to computer systems. Things such as motherboards, RAM, HDDs, etc. Computer devices with exposed capacitors, pins, wires, contacts are hardware.

BUS: The interconnectivity of wires between various components that the computer needs to send information to and from. The BUS is the main bottle neck of ANY computer. Eliminate the need for a bus and processing speeds will increase exponentially.

Resource: The measurement or percentage of the system being utilized versus the amount of system that can be used to do other and or more tasks. Each task dictated to the computer requires a certain percentage of the system’s resources. The more memory, the faster the CPU(s), the quicker the BUS, the more resources you will have to do more tasks or “multi-task”.

Storage: Storage usually comes in two flavors: Network Storage and Local Storage. Either way you look at it, storage is the amount of memory you have to retain data (non volatile). For the most part this includes HDDs, some sort of Flash Memory, and SSDs (my absolute favorite). Remember to be redundant; don’t learn about redundancy the hard way… (

I/O Device: Technically speaking, any device that can both give and receive data from/to a computer. A cd/dvd/blu-ray-burner drive is an I/O device because you can write to it, and obtain data from it. A mouse is an input device only; you can only give the computer coordinates to where to move the pointer. A flash drive is an I/O Device because you can move data to and from it.

RAM: Random Access Memory, a major component in any computer, server, or high load printer. RAM is volatile, so it will lose any data stored there when the computer or printer is reset or powered off. There are many different types of RAM chips. There are tons of different factors, speeds, module sizes, timings, etc. RAM works very closely in aiding the CPU with the communication of all the devices associated with the computer. Every instruction or task the CPU has to do needs to be stored somewhere. Since RAM access is extremely fast, we use RAM instead of the HDD, although sometimes the HDD is used when the amount of RAM is lacking. IE: “Virtual Memory”.

System Software: Software that enables the OS to work affectively. All “Behind the scenes” type software that enables the user to have a happy, friendly GUI to use. System Software includes compilers, loaders, linkers, and debuggers.

Application: Applications are end-user programs. Pretty much anything the user wants to install and use is an application with the exception of plugins: (Flash/Shockwave/Java). Microsoft Office, Nero Burning-Rom, PowerISO, Sound Forge, Adobe Photoshop CS4, and Acrobat are all examples of applications.

Microcomputer: A broad category that includes the most popular form factors used today. Microcomputers are laptops, notebooks, PCs, and now even servers. Since computing has expanded so vastly, even microcomputers make fantastic servers that can support hundreds of users at once. Even rack mount servers are considered microcomputers. Microcomputers are in contrast to mainframes which are now severely outdated. The term “Microcomputer” is certainly dated, and we have since then dropped the “micro” part.

b)
OLED Technology: Organic Light Emitting Diode. This is the display of the future. Each diode is individually lit! This is absolutely amazing. OLED displays offer the brightest, most saturated and color correct, widest viewing angle, lowest latency, and highest contrast picture ever. Not to mention that displays are 3 millimeters thick and the screen can actually bend! LCD screens, plasma screens, and LED-LCD screens are already outdated. The limiting factor right now is the cost, but in retrospect, one has to keep in mind when plasma screens first came out, they were fifteen thousand dollars; the first OLED display to come out is a mere three thousand… OLED technology is so groundbreaking that the “armed forces” has been conducting research and development for quite some time. What they have been working on is on the border of science fiction; it’s absolutely incredible. (If we are doing a paper for this class I’d love the opportunity to do it on this topic, I know I’d do a good job because I am sincerely excited about it.)

** http://www.oled-display.net/how-works-the-oled-technology **

SSD Technology: Solid-State Disk: It’s about damn time… Finally a disk that is not prone to rapid break down. Solid state is basically a flash drive on steroids. Not only are the read and write times blazing fast, but you can drop it and smack it around and it will 9 times out of 10 be unscathed. Stripe (RAID-0) a few SSDs and you are booting within seconds. The power consumption is much less than a conventional HDD, so in laptop you can expect much better battery life. The limiting factor is the cost.

...Accountability and Ethics Computer Addiction and Cyber Crime Nick Nykodym The University of Toledo Sonny Ariss The University of Toledo Katarina Kurtz The University of Toledo This research explores the relationship between computer addiction and cyber crime. There is evidence of computer addiction in medical settings, scholarly journals and legal proceedings. Reviewing the history of computer addiction has shown that computer addiction can be related to cyber crime. This paper will define computer addiction, show how various cyber crimes, especially those against businesses and organizations, can be motivated by computer addiction and propose further research on how managers can deal with cyber crime in a business, by recognizing addictive behaviors and computer addiction in their employees. HISTORY OF COMPUTER ADDICTION Computer addiction is an idea that has been in existence for years. Since the 1970s, avid computer programmers and hackers have been called “addicts” by both psychologists and the general public (Reed, 2002, p. 135). In 1976, Weizenbaum wrote about computer programmers who could sit and work at their computer terminals for twenty or thirty hours at a time. This behavior however, was viewed at the time as useful to technology and society. Computers, once seen as huge government machines that only very knowledgeable people could use, transformed into user-friendly tools that could be used by the everyday person. It became more common to see computers in......

...Computers types I, Computer: Definition A computer is a machine that can be programmed to manipulate symbols. Its principal characteristics are: § It responds to a specific set of instructions in a well-defined manner. § It can execute a prerecorded list of instructions (a program). § It can quickly store and retrieve large amounts of data. Therefore computers can perform complex and repetitive procedures quickly, precisely and reliably. Modern computers are electronic and digital. The actual machinery (wires, transistors, and circuits) is called hardware; the instructions and data are called software. All general-purpose computers require the following hardware components: § Central processing unit (CPU): The heart of the computer, this is the component that actually executes instructions organized in programs ("software") which tell the computer what to do. § Memory (fast, expensive, short-term memory): Enables a computer to store, at least temporarily, data, programs, and intermediate results. § Mass storage device (slower, cheaper, long-term memory): Allows a computer to permanently retain large amounts of data and programs between jobs. Common mass storage devices include disk drives and tape drives. § Input device: Usually a keyboard and mouse, the input device is the conduit through which data and instructions enter a computer. § Output device: A display screen, printer, or other device that lets you see what the computer has accomplished.

A tablet computer may be connected to a keyboard with a wireless link or a USB port. Convertible notebook computers have an integrated keyboard that can be hidden by a swivel joint or slide joint, exposing only the screen for touch operation. Hybrids have a detachable keyboard so that the touch screen can be used as a stand-alone tablet. Booklets include dual-touchscreens, and can be used as a notebook by displaying a virtual keyboard in one of them. An early information tablet concept, named the Dynabook, was described by a Xerox scientist Alan C Kay, in his Aug 1972 paper: A Personal Computer for children of all Ages, the paper proposes a touch screen as a possible alternative means of input for the device. The first commercial portable electronic tablets appeared at the end of the 20th century. In 2010, Apple Inc. released the iPad which became the first mobile computer tablet to achieve worldwide commercial......

...Input and Output Devices The devices which are used to input the data and the programs in the computer are known as "Input Devices". or  Input device can read data and convert them to a form that a computer can use. Output Device can produce the final product of machine processing into a form usable by humans. It provides man to machine communication. Before a computer can process your data, you need some method to input the data into the machine. The device you use will depend on what form this data takes (be it text, sound, artwork, etc.). Similarly, after the computer has processed your data, you often need to produce output of the results. This output could be a display on the computer screen, hardcopy on printed pages, or even the audio playback of music you composed on the computer. The terms “input” and “output” are used both as verbs to describe the process of entering or displaying the data, and as nouns referring to the data itself entered into or displayed by the computer. Below we discuss the variety of peripheral devices used for computer input and output. Input Devices Keyboard: The computer keyboard is used to enter text information into the computer, as when you type the contents of a report. The keyboard can also be used to type commands directing the computer to perform certain actions. Commands are typically chosen from an on-screen menu using a mouse, but there are often keyboard shortcuts for giving these same commands. In......

Term Paper About Computer History

...History of Computers Computer history can be traced back since the 1880s from the advent typewriting and mechanical counting prototype and also companies such as the National Cash Register which made the atm machines we use today to withdraw cash. John Vincent Atanasoff was a physicist who invented the electronic digital computer. The first electronic digital computer was an idea whose time had come; several groups working more or less independently arrived at almost the same place at the same time. Atanasoff was simply a bit ahead of the pack and for him being ahead had a cost. Atanasoff was required to work alone in a place far removed from the mainstream of computer development. He had trouble finding anyone who recognized the significance of his work. Iowa State supported Atanasoff's work, but none of the university officials fully appreciated what he was up to. Computers have been around since World War II used by the military against the enemy. The Germans used the enigma code machine during the war to secretly send code messages. The enigma code machine was one of their secret weapons they used against the allies. The Enigma offered 150 quintillion possible combinations. Computers have changed since then and now have better versions. Then came the Xerox Parc Alto personal computer developed in 1973, which was a breakthrough then with its built-in mouse and the use of windows. The CHM described it as the Macintosh 10 years before it hit the market. In 1976 apple......

...ROLE OF COMPUTERS About two hundred years before, the word "computer" started to appear in the dictionary. Some people even didn't know what is a computer? However, most of the people today not just knowing what is a computer, but understand how to use a computer. Therefore, computer becomes more and more popular and important to our society. We can use computer everywhere and they are very useful and helpful to our life. Computers have brought about a tremendous revolution in every walk of life and are expected to open more vast fields due to the dexterity of those who design software and those who develop application programs. In a very short period, scientists have been able to extirpate all the defects, the limitations and the shortcoming of computer and much is expected from their ingenuity, acumen and acquisitiveness. The fields of application of computers are various and new applications are being searched out. The scientists applied it to prediction of weather earthquakes, and storms, controlling of satellites and controlling of atomic reactions in reactors and else where. Engineers have not lagged behind. They use computers in designing cars aeroplanes, ships, buildings, bridges and tools etc. In the business world, computers are playing great parts. They are used to word processing, record keeping, inventory controlling, patrol processing, account keeping and auditing, stock marketing and ticket reservations. They are now used to keep personal telephone and......

...A computer is a programmable machine designed to sequentially and automatically carry out a sequence of arithmetic or logical operations. The particular sequence of operations can be changed readily, allowing the computer to solve more than one kind of problem. An important class of computer operations on some computing platforms is the accepting of input from human operators and the output of results formatted for human consumption. The interface between the computer and the human operator is known as the user interface. A computer is like a brain which can think, calculate, retrieve and organize information for its human master. This brain is supplied with parts that provide allow for input to it and allow it produce output for presentation to the one using it. Central Processing Unit The thinking part of the brain of the computer is the CPU or Central Processing Unit. This component provides all the control and manages calculations and manipulation of data. Computer manufacturers are always trying to squeeze more speed and multiprocessing capability (doing multiple things at the same time) out of it. This has led to the dual core or multiple core CPU which is popular today. A core is basically a computer so that a dual core computer is really 2 computers in one. Computer speed is usually measured in GHz which means Gigahertz which in turn mean billions of cycles per second. The basic idea is that the higher the number of cycles, the faster the computer is.
