    cameras that also use the internet. d) Transportation, which saw 1.1 billion automobiles in 2010 These factors has led to a rapid decline in available addresses for IPv4. Several methods were implemented in order save the remaining addresses. One of them included the use of Network Address Translation. NAT provides a method of allowing several addresses to be connected to the internet through a public IP address. There are many problems associated with NAT which is not prevalent in IPv6. This has seen a drastic improvement in performance by using IPv6. External Data Representation IPv6 uses hexadecimal notation which includes colons for external data representation, instead of the dotted decimal notation by IPv4. (E.g. 2011:420:30::3 vs. 124.31.52.58) The representation of an IPv4 addresses externally has 4 fields which consists of 8 bits. These fields are separated by dots and the leading zeros are suppressed in each field. IPv6 on the other hand has an external representation which can have up to 8 fields consisting of 16 bits, using four hexadecimal digits in each field. Fields are separated by colons and leading zeroes can also be suppressed. If there are zeros that are repeated, it can be replaced by two colons “::” for one string. This helps to condense the string which will be easier to read and analyse rather than having a string which is 16 bits long. Packet Header The packet headers are attached at the beginning of all IP packets. A packet header contains both…

  • What Is The Evolution Of Zero Essay

    to introduce the Hindu-Arabic number system into Europe. It was the positional system that we currently use today based on ten digits with its decimal point and most importantly a symbol for zero. In the new system the order of the number mattered since for example, twenty-five is completely different than fifty-two. The position of each digit was significant, therefore zero was needed to get digits into their correct places. For example, writing two thousand and five required two zeroes in…

  • Compare And Contrast Ancient China And India

    60 was used for basic math and 360 was used for circles The Sumerians also gave us the decimal system. The Hindu’s gave us the Arabic Numeral System which gave mankind counting numbers. With the extension of numbers, math took off. The Hebrew’s gave us another numeral system but this one went into the hundreds. The Babylonians gave us the digit 0 and then we had a a completed number system for that time. Agriculture was a ginormous element when civilization was first coming together and it has…

  • Essay On Place Value Knowledge

    interesting, they said “I know how to work this out, you look at the first two numbers and then you look at the last numbers”. The child placed 2900 before 2092 when asked to place the numbers in order from smallest to largest. This misconception shows that the child’s understanding of place value, particularly with larger numbers is confused as they believed the ‘92’ was larger than the ‘00’ but they did not consider the numbers in the hundreds and thousands places. The child also wrote…

  • Personal Statement: My Interest In Computer Science

    This summer I built the classic puzzle game Bejeweled, and abstract strategy games English Draughts and Chess. I did this because I am a big fan of all three of these games, and I wanted to challenge myself by implementing the game logic. Also during the summer I started learning android. The app that I built that I am most proud of is a calculator that works in sixty different numeral systems from base 2 to base 62. I started the project making a calculator that uses hexadecimal instead of…

  • Nt1310 Unit 1 Computing Assessment Paper

    simplicity of the binary number system means it is ideal for a system that only requires two outputs, a negative or a positive. Logic gates are configured for example to produce results of either one or zero depending on the output. A voltage of less than three volts is considered as an output of zero while between zero and five the output is one. Performing operations with such few outputs enhances the ability of the computer to perform complex computations accurately, timely and without errors…

    Boris is confident in their 2’s, 3’s, 4’s and 5’s skip counting, however they are not experienced in anything above 5’s. The butterflies were different colours and not standard dots or squares, they were also misarranged, which caused some hesitation until I showed Boris how to mentally and physically (with a finger on each, or imagining groups of) reposition them or to regroup. Pony calls and Partitioning of numbers was another lesson firmly grounded in fun. Racing against a timer to…
