Section 1 “History of Computers”

ENIAC was the first general-purpose electronic computer. It was capable of being re-programmed to colve a full range of computer problems. It was designed for the purpose of calculating artillary firing tables for the U.S. army reasearch laboratory. It was heralded as a “Giant Brain” in 1946. It contained 17468 vaccum tubes as well as 70,00 resistors and many other important parts. The ENIAC could aslo be programmed to perform complex sequences of operations including loops, branches, and subroutines.

Vaccum tubes size are larger sized and have a heavier weight than a transistor.

A transistor is a semi-conductor device commonly used to amplify or switch electronic signals. It is made mostly of strong piece of semiconductor paper. It can be referred to as a fundamental buiding block for modern day technology such as radios, telephones and computers. The first patent for the field-effect transistor was filed here in Canada by a physicist by the name of Julius Edgar Lilienfield. Many consider the transistor to be the greatest invention of the 20th century. Due to its low cost, felxibility and reliaility, the transistor an extremely significant device. They are commonly used as electronic switches for high power applications as well as low power applications.

IC (integrated circuit) is a miniaturized electronic circuit consisting mainly of semiconductor devices. The integrated ciruit was first brought about by a radar scientist who went by the name of Geoffrey W.A. Dummer. However, it would later go on to be re-inevtned by Jack Kilby and Robert Noyce.

The Timex Sinclair was a joint venture in an attempt by the Sinclair Research company and Timex corporation to launch one of the first home computers in the early 1980s. Timex Sinclair was later succesful in producing 4 computersbased on Sinclair Research’s existing machines (TS1000, TS 1500, TS2068, TS2048).

The First Home computer was finished in 1942when its creator, was called up for a war effort. For quite some time, the ENIAC goliath took credit for bring the first home computer. Clifford Berry was the man who built this fascintating machine and felt the hardships due to his non-recognition of building the computer. He was upset with not getting the credit he so well deserved.

ICT Assignment

This year is said to be one of the hardest years in our academic journey for success. This year I would like to strive to achieve my best in all my subjects. In order to make this goal a reality, I need to accomplish certain tasks. These taks being completing all my courses with an 86% or higher grade, not becoming involved in any sort of trouble and be the best I can be.

I would say at this point in age I enjoy technologies such as computers, tv’s, game consoles and cell phones. Like any boy my age these are few of the many technologies I am interested in today. I find these technologies interesting because they help you to  better observe the world around you in many shapes an forms. I also like the idea of how everyday our technolgies change and become more efficient such as hybrid cars these days and computers. Eveything is becoming more size-efficient or suitable for all ages or needs.

One piece of technology I could not live without would have to be my computer. This would be because my computer holds everything I enjoy. It also gives me the opportunity to see the differnece and what goes on in the world around me. Such as what is new in the world and just simple things such as local news. So if I had to choose a technology in which I could not live without it would have to be my computer!

This year in this particular course I would like to learn more about all sorts of technologies and their proper use and how to operate them in the correct manner. I would like to learn about how they are made and all new advanced forms of technology and how they originated. Thsi course seems like a very interesting course and I am glad to be participating in it!

Definitions

Hard drive:   A disk drive that reads data stored on hard disks.

CPU: Central Processing Unit; a central computer unit that controls the activities of other units connected to it.

Motherboard: The main board of a computer, usually containing the circuitry for the central processing unit, keyboard, and monitor and often having slots for accepting additional circuitry.

Power supply: A device that provides power to electric machines, generators, etc.

PCI: Peripheral Component Interconnect

PCI expresss: Peripheral Component Interconnect express (faster).

USB: Universal Serial Bus

Firewire: Apple’s name for IEEE 1394 interphase

IEEE-1394: a serial bus interface standard for high-speed communications and isochronous real-time data transfer, frequently used in a personal computer

LCD: liquid-crystal display: a method of displaying readings continuously, as on digital watches, portable computers, and calculators, using a liquid-crystal film, sealed between glass plates, that changes its optical properties when a voltage is applied.

Plasma (screen):  a type of flat panel display now commonly used for large TV displays (typically above 37-inch or 940 mm).

HDMI: a compact audio/video connector interface for transmitting uncompressed digital streams.

RAM: a type of computer data storage. Today it takes the form of integrated circuits that allow the stored data to be accessed in any pie order, i.e. at random. The word random thus refers to the fact that any piece of data can be returned in a constant time, regardless of its physical location and whether or not it is related to the previous piece of data.^[1]

^{Flash Memory:} non-volatile computer memory that can be electrically erased and reprogrammed. It is a technology that is primarily used in memory cards and USB flash drives for general storage and transfer of data between computers and other digital products

AGP: a high-speed point-to-point channel for attaching a graphics card to a computer’s motherboard, primarily to assist in the acceleration of 3D computer graphics.

DVD: a popular optical disc storage media format. Its main uses are video and data storage. Most DVDs are of the same dimensions as compact discs (CDs) but store more than six times as much data.
