Von Neumann computer architecture
Background
John von Neumann 1903-1957 was a child-prodigy; he received his Ph.D. in mathematics from Pázmány Péter University in Budapest at the age of 22, while also earning a diploma in chemical engineering from the ETH Zurich in Switzerland.
During his work on the Manhattan Project he happened upon a chance meeting with Lieutenant Herman Goldstine, who he himself was working on a military project that evolved creating a computer system that could help calculate the trajectories of the army’s heavy gun’s shells, this project was known as Electronic Discrete Variable Computer (EDVAC). Von Neumann wrote an incomplete set of notes, titled the First Draft of a Report on the EDVAC. This widely distributed paper

• Accumulator (AC) and multiplier quotient (MQ): Employed to hold temporarily operands and results of ALU operations. For example, the result of multiplying two 40-bit numbers is an 80-bit number; the most significant 40 bits are stored in the AC and the least significant in the MQ.
What are Machine instructions and how do they get processed in the CPU
A machine instruction asks the processor to perform a certain operation. It is made up of two types of code, operation code (op code) operand. The op code is the action, all though modern processors are limited at the machine level to instructions with no more than two operands the operands can be one or more type of instructions and are commonly grouped by the following headings;
• Data transfer: Move data between memory and ALU registers or between two ALU registers.
• Unconditional branch: Normally, the control unit executes instructions in sequence from memory. This sequence can be changed by a branch instruction, which facilitates repetitive operations.
• Conditional branch: The branch can be made dependent on a condition, thus allowing decision

It might have been Aiken’s idea but he needed the money and resources to build this project, this brought doubt into who actually built the computer? Although like said before it was Aiken’s paper inspired the project, it was IBM who had to provide the required components to build this computer and in some instances develop specialised components in order to finish. The finished computer was built using electromagnetic components instead of the more traditional methods such as an electrical system. The Mark 1 was built between 1939 and 1944 and was primarily used in World War II by the US Navy, to help protect of ships from being destroyed by magnetic mines in the sea, and also help manage radar system’s not to forget but also further design of these radar

Syntax : # , MOVEx #5D0B,(ARx0)+ //here, 5D0B is stored in Address specified in ARx0 Register and value in ARx0 is incremented
In this it contains sequence of elements and new elements are added at top 2. In this removing elements is also performed from only top. 3. To remove the first inserted element we have to remove all elements from it Queue: It uses FIFO method means First in First Out 1.

Carey describes in his book “ PV Ventura/Harpoon Units of WW II”, “Night fighting was a complicated undertaking which involved not only the aircraft and crew, but a ground controller (Ground Control Intercept (GCI), using a mobile scr-527A radar) whose task it was to guide the aeroplane to the interception point, where the PV-1 radar operator took over locating the “bogey” (enemy aircraft)”. Staff Sgt. Ralph W. Emerson of Minot, Maine was one of the first marines to be trained and assigned as a PV-1 radar operator. Ssgt. Emerson joined the Marine Corps in September, 1941, and after basic training at Parris Island, he was sent to aviation and radar school.
There are similarities between Chris McCandless and Henry David Thoreau, but there is also many differences. Chris and David’s thoughts on the following ideas are just some of the many similarities they have: transcendentalism, materialism, individualism, and nature. One difference between McCandless and Thoreau is that Thoreau studied and enjoyed technology, while McCandless did not. The two characters may have extensive similarities, but their differences characterize their personalities.
The USS Yorktown contained twenty-seven different computers. Each and every one of these computers had 200 MHz
This was a major advancement because no other navy had such technology and World War 1 marked the beginning of submarine and underwater warfare.
Moore School of Electrical Engineering in secret. The ENIAC was finally completed in November 1945 and tested (used to test—zs) the feasibility of the hydrogen bomb, which was deemed successful. It was introduced to the public in February of 1946 as a “thinking machine.” After the creation and completion of the ENIAC, Mauchly and Eckert thought about creating a potential commercial use of a computer, similar to today’s laptops and desktops, which was visionary at the moment.
One of the biggest challenges was crossing no-man’s land. The space, between the trenches, provided an easy target for enemy soldiers and was cover in barbed wire, which entangled soldiers. As a solution, the tank was invented. In 1916, the first tank, known as Mark I, was taken into battle. The machine could run over the barbed wire with ease and could protect soldiers with its shield of durable metal.
Innovation assumed a critical part in World War II. A portion of the innovations utilized amid the war were created amid the interwar years of the 1920s and 1930s, much was produced in light of necessities and lessons learned amid the war, while others were starting to be produced as the war finished. Numerous wars effectsly affected the advancements that we use in our day by day lives. Notwithstanding, contrasted with past wars, World War II had the best impact on the innovation and gadgets that are utilized today. Innovation likewise assumed a more noteworthy part in the behavior of WWII than in whatever other war ever, and had a basic part in its last result.
Turing himself unknown to him, created a great race to make a better and more complex artificial intelligence with this paper. The article since 1950 has been cited over 10,000 times. The way this article revolutionized has not been matched by any other paper in the computing world. Turing himself wore many hats in his life. He was mathematician, code breaker and computer scientist.
The human race has got to see some of the top best inventions during the 20th century, for example- the radio, the airplane, nuclear power, automobile, and the one that has by far made human life easy and efficient is the computer. The invention of the computer has led to some of the most significant concepts, ideas, and inventions that eventually led to the evolution of human life. And the major ones are, the internet, long distance communication, easy and safe research and much more! The computer was invented by Charles Babbage, an English mechanical engineer, and polymath who is also titled as the “father of computers”.
Pranav Patil Computer Science STATEMENT OF PURPOSE INTRO I believe that the ability to invent, innovate and discover is what has propelled man to the echelons of success. Throughout my life, I have been driven by the desire to “create”, a capability that transcends the passive acquisition of knowledge. It is always the unknown path that has enthralled me more than known terrain. In a world where everything from fighter jets to elevators, interactive graphic displays to digital watches, is driven by computers, I found it difficult not to get fascinated by the technology involved.
The origins and roots of computers started out as many other inventions and technologies have in the past. They evolved from a relatively simple idea or plan designed to help perform functions easier and quicker. According to Gary Masters “the first basic type of computers were designed to do just that to compute”. They
