• 1939 Hewlett-Packard is founded. David Packard and Bill Hewlett found Hewlett-Packard in a Palo Alto, California. Their first product was the HP 200A Audio Oscillator, which rapidly becomes a popular piece of test equipment for engineers.
• 1940 The Complex Number Calculator (CNC) is completed. George Stibitz demonstrated the CNC at an American Mathematical Society conference at Dartmouth College. Stibitz performed calculations remotely on the CNC using a Teletype connected via special telephone lines. This is the first demonstration of remote access computing.
• 1941 Konrad Zuse finishes the Z3 computer. Using 2,300 relays, the Z3 used floating point binary arithmetic and had a 22-bit word length.
• 1942 The Atanasoff-Berry Computer (ABC) is completed. The ABC was designed and built by Professor John Vincent Atanasoff and graduate student Cliff Berry between 1939 and 1942.
• 1944 Harvard Mark-1 is completed. Created by Howard Aiken, and designed and built by IBM, the Harvard Mark-1 was a room-sized relay-based calculator. This machine had a fifty-foot long camshaft that synchronized the machine’s thousands of component parts.
• 1946 The first glimpse of the ENIAC, a machine built by John Mauchly and J. Presper Eckert that improved by 1,000 times on the speed of its contemporaries.
• 1949 Maurice Wilkes assembled the EDSAC, the first practical stored-program computer, at Cambridge University. For programming the EDSAC, Wilkes established a library of short programs called subroutines stored on punched paper tapes.

...is to first know that 1 byte is equal to 8 bits as well as what each component is exactly. A bit is defined as:” a single basic unit of information, used in connection with computers and electronic communication”. (Quote, n.d.) A byte is “pronounced ‘bite’, is the next size up basic unit of measurement for information storage, usually consisting of 8 bits”. (Quote, n.d.) The next set of terms that are used is: Kilo (kilobytes) equal to 1,000 bits stated in decimal form or 1,024 bytes stated in binary form. Then we have Mega (megabytes) equal to 1,000,000 decimal bits or 1,048,576 binary bits. Next is one of the bigger bytes and that is Giga (gigabytes) which is equal to 1,000,000,000 decimal bits or 1,073,741,824 binary bits. After figuring out the numbers to these complex bits of information, the next step is to understand the speed of transferring data. This is simply downloading information and what speed is required to effectively transfer the data. This unit of measure is ‘bits per second’ (bps) and is usually measured in thousands of bits per second or kilobits per second (kbps). The prefixes for the above data are: Kilobits per second, 1,024 (Kbps), Megabit per second, 1,048,576 (Mbps) and Gigabit per second, 1,073,741,824 (Gbps). But how does this all come together to form our computers and the internet the way it is today? First of all the data that can be transferred and the rate in which it can transfer is called bandwidth (speed) and broadband “is a......

The union of Upper and Lower Egypt was important the development of Western Civilization because it was where the essential and remembered elements of the Egyptian civilization were established and finalized as well as when the pyramids where built that thousands of people visit every year. The union of Upper and Lower Egypt was accomplished when Narmer, or Menes, conquered the Nile Delta and Lower Egypt. Doing this centralized Menes’ rule and began construction of the great pyramids; during the times of the construction of the pyramids. The pyramids were giant tombs for Egypt’s pharaohs who were ,at that time, considered to be both man and god, who was the absolute ruler of the land and decided whether Egypt would flourish or not. In the pyramids “pyramid text” or hieroglyphics, which were an early form of writing using pictures represented words or sounds, was written on the walls of the tombs. Under Menes’ rule the first Egyptian dynasty was formed, and Egyptian cities became the center of religion and government. The union of Lower and Upper Egypt or Old Kingdom is what the later Egyptians looked to for their future decisions believing the ways of the Old Kingdom, or their ancestors, were best.

...Description and Significance of the People/Event(s) to American History

 1) Describe three different American Indian cultures prior to colonization.( Approx. 1200- 1900 C.E.) The Anasazi inhabited the Southwest including Colorado, Arizona, Utah and New Mexico. They were artisans in stonework, cotton fabrics, and basketmaking. They were agriculturalists and astronomers, and built elaborate dwellings and road networks for trade. The Iroquois were one of the largest tribes, dividing into a League of several nations with diverse languages and traditions and were best known as the People of the Longhouse for their multigenerational dwellings. Algonkian tribes were located in the Northeast and were the first to encounter Europeans. The Algonkians subsisted on both hunting and agriculture.

 2) The effects of British colonization on the Native Americans. (1600’s)

The British began by building houses in an unobtrusive way which led the indigenous people to believe they could co-habitate, but as the English spread, the natives were forced to move or fight for their land. Eventually interactions with the British led to domination of Native Americans not only by taking their land, but through spreading devastating diseases for which Native tribes had no immunity and through religious subjugation.

 3) The evolution of the socio-political milieu during the colonial period, including Protestant Christianity's impact on colonial social life. (1600-1700’s)

Nt-1110 Unit 6 Research Paper

...Matt Bristow NT-1110 Unit 6 Research Paper NAS Devices NAS is an acronym for Network-Attached Storage. It is basically a file-level computer built for data storage connected to a computer network providing data access to any computer connected to that network. The speed for any particular NAS device varies from 1 gigabit all the way up to 10 gigabits depending on what upgrades a pc has such as an upgraded network cards. The capacity range for NAS devices also depend solely on the budget set forth. It can be a low range system with 500 gigabytes, all the way up to a wallet-busting 16 terabytes. The fault tolerances when set at RAID 10 are the most stable since more devices can fail while protecting against any potential data loss. The advantages of an NAS device are that since it is a dedicated file storage device, accessing said data is a lot faster than typical in-pc hard drives. Another advantage would be the amount of storage you're capable of having. It far outpaces pc's in storage capabilities because all it is built for is storage. For a family with a lot of pictures or videos, the advantages are that any computer connected to the NAS device can access them. It's a library for any media/documents/or anything else you can think of that can be accessed at any time by any pc connected to it. They might be pricey for a casual pc user but when dealing with multiple pc's connected to a single network, an NAS device would be the perfect option when space becomes an issue...

Windows vista had problems sometimes with the start menu not always working properly. The fourth feature that has changed a little is the taskbar. They have had the taskbar around since almost the beginning. On the taskbar it includes the start menu button, quick launch buttons, any open programs, icons for running programs, and the clock. The taskbar is a huge part that helps you with whatever you are trying to do on windows 7. The final feature that has changed is windows explorer. Now in windows explorer they added libraries. In the older versions you just saw, for instance, documents, videos, and music. Now with the libraries it helps searching for certain types of files or folders easier, even if they are spread all around your computer.

History of Computers

...History of Computers 1. History of Computers This chapter is a brief summary of the history of Computers. It is supplemented by the two PBS documentaries video tapes "Inventing the Future" And "The Paperback Computer". The chapter highlights some of the advances to look for in the documentaries. In particular, when viewing the movies you should look for two things: * The progression in hardware representation of a bit of data: 1. Vacuum Tubes (1950s) - one bit on the size of a thumb; 2. Transistors (1950s and 1960s) - one bit on the size of a fingernail; 3. Integrated Circuits (1960s and 70s) - thousands of bits on the size of a hand 4. Silicon computer chips (1970s and on) - millions of bits on the size of a finger nail. * The progression of the ease of use of computers: 5. Almost impossible to use except by very patient geniuses (1950s); 6. Programmable by highly trained people only (1960s and 1970s); 7. Useable by just about anyone (1980s and on). to see how computers got smaller, cheaper, and easier to use.
