Principles Of Software Development
Principles Of Software Development Gagandeep Singh (a) Different types of number system:- 1 binary The binary number system can be represented by 2 digits (0 and 1) . all the data of our computer is in the form of binary numbers. Binary number is mostly used in electronic circuit to check there voltages (i.e., on/off switch) where 0 consider when switch is off and 1 when switch is on. Moreover the base of binary number is 2 because it has only 2 digits and each binary digit is known as bit. Examples-a (010101)2                      B (1010.101)2 Decimal:- decimal number system can be represented by 10 types of digits from 0 to 9, so the base of decimal number system is 10. This is one of the most simple and familiar with everyone. Examples-A (456374)10                     B (143.345)10 Octal:- it can be represented by 8 different types from 0 to 7, so the base of octal is 8. The group of 3 binary digit is equal to 1 octal number. For example- 000 binary number is equal to 0, 001 binary number is equal to 1 and so on. Moreover in this octal number system any digit is always less than 8 because 8 has not a valid digit. For example-a (6342)8                                                               B (2473.564)8 Hexadecimal:- hexadecimal can be represented by 16 digits from 0 to 15 but 0 to 9 can be in digits but 10 to 15 in alphabets like 10 =A, 11=B, 12=C, 13=D, 14=E, 15=F. Only complex or wide numbers are used in this system. For example-A (CD45)16                          B (D77.4A6)16. (codesand tutorials) (b) convert 10310 to binary Answer = binary 1100111 Hexadecimal is 67 Octal is 147  (c) Convert (1011010)2 to decimal and hexadecimal. Answer = Decimal (1011010)2 (1011010)2 = 126 + 0x25 + 124 + 123 + 0x22 + 121 + 0x20 = 164 + 0x32 + 116 + 18 + 0x4 + 12 + 0x1 = 64 + 0 + 16 + 8 + 0 + 2 + 0 = (90)10 Hexadecimal is 5A.  Integer it consist whole number that can be positive or negative like 12, 0, -12 or 1344. But integers cant be in decimals. It is used to search the items in the computer with the help of array. It occupy 2 and 4 bytes. And the range for signed integers is -32,468 to 32767 or -2,147,483,648 to 2,147,483,647. For unsigned the range value is 0 to 65,535 or 0 to 4,294,967,295. Example:-     Int id; (Techterm) Character a character may be any letter, number or symbol than can be typed on computer. There are two types of the character data types. Signed and unsigned. Each character occupy 1 byte of storage. Range of signed char is -128 to 127 and for unsignedis 0 to 255. Example:- Char name; (techterm) Float when we want to store a decimal values in the variable than we can say this is float. It is also known as real number data type and the storage size of float is 4 bytes. The range is 1.2E-38 to 3.4E+38. Float avg; Double when we have to use data type on big eateries that type of data is double data type. Moreover storage size of double data type is 8 bytes. Boolean-when we have only two option like yes/no or true/false then we can say this type of data is known as Boolean data. Different types of coding system 1. BCD Code The full form of BCD is binary coded system. It has represented by 4 binary digits because it has 4 bit code. This code is mostly used in the past. 2. EBCDIC Code EBCDIC means extended binary coded decimal interchange code which can be represented by 256 characters and it has 8 bit code. 3. ASCII ASCII stands for American standard code for information interchange. The founder of this is ANSI (American National Standard Institute) in 1968 and mostly prefers to use on personal computer. It has 7 bit code which can be represented by 128 characters. This code is not enough to represent the graphics character on computer screen. As 8 bit character represent 256 character and the extended 128 character has unique code represent graphic symbols. 4. Unicode Unicode has a 16 bit code and it can be representing by 65536 characters. The main purpose of this is to replace ASCII code because it can represent all the characters of all languages in the world. (Ameen, 2011) 5 Barcode A barcode is just like a image of small lines which shows the retails and identify the particular items. The code of the product is entered in the computer before to put on the shells. Moreover it has five main parts : a quiet zone, a start character, data character, a stop character, and another quiet zone. (manufacturingERP)

The Importance
The Importance Paulo Coelho explained, â€Å"Why is patience so important? †â€Å"Because it makes us pay attention. †Being patient and attention to detail are few of many characteristics that are essential to being a proficient healthcare provider. Healthcare providers have a very important job and these characteristics correspond to one another in everyday actions. I always thought of myself as a very patient person and while working at a daycare realized that along with patience came the importance of attention to detail.Patience is very easy to describe when telling one how to do things, but putting it into practice and living in such manner takes one’s self-control. I have always enjoyed interacting with kids and when I had to get a job in high school, I decided that a daycare would be a great opportunity. The majority of my time was spent caring for toddlers. Patience is essential when working with toddlers.I had to juggle chasing around squeamish, playfu l, emotional kids who were going through their first year of life and preparing to move on to their terrible twos. There were many times when three or four kids were screaming and crying, and, at times I felt overwhelmed but had to keep my composure, so that I could calm them down. Attention to detail is important as it points out and makes one realize how to do things right. While working with toddlers, I had to learn that when chaos was going on somebody needed attention.Daily I practiced observing details, such as when a toddler got whiny and upset; I had to remain patient throughout their crying and see whether they were in need of a diaper change or had gotten hurt. Patience and attention to detail for a healthcare provider can determine the outcome of a patient’s health. As I cared for toddlers my interest and desire for working with children grew. I reconfirmed that I had the characteristics of knowing how to take important issues with time and preciseness to assure th at nothing of importance is left out.

Marriage in 18th Century Europe Essay - 1004 Words
Marriage in 18th Century Europe The major movement regarding marriage in the eighteenth century was from church to state. Marital laws and customs, once administered and governed by the church, increasingly came to be controlled by legislators who passed many laws restricting the circumstances and legality of marriages. These restrictions tended to represent the interests of the wealthy and uphold patriarchal tradition. Backlash to these restrictions produced a number of undesirable practices, including promiscuity, wife-sale, and divorce. Before the eighteenth century, marriage was far less complicated. Verbal consent and consumation constituted legal marriage: once the knot was tied by such verbal exchanges it could not be†¦show more content†¦shall incur the penalty of the law now enforced against witchcraft and like misdemeanors, and that the marriage upon conviction shall stand null and void. (Murstein 227) In 1753, Lord Hardwickes Marriage Act was passed in an attempt to do away with unlicensed marriages and protect the rights of the wealthy. It voided premarital contracts and prohibited marriages of those under 21 without parental consent. The act also required a license for marriage and a public announcement thereof. Anyone who disobeyed these laws would find their marriage voided and themselves banished for fourteen years (Outhwaite 78-9). This act was principally designed to restrict unlicensed and undesirable marriages between social classes. By requiring parental consent the act gave parents the right to invalidate any marrriage they considered undesirable. English legislators expressed relief at having done away with foolish notions of romantic love in favor of more practical statutes governing the institution. According to Murstein, among the wealthy, marriage was primarily a business arrangement (206).
