11 | 9 | 2015 I played six water polo games last weekend! I was at the pool from seven o’clock in the morning till seven thirty at night‚ and I never got the chance to leave the pool deck. I didn’t even get the chance to eat really. I was the first game in the morning‚ and that last game at night. It was really fun though; I scored two goals. I played in two different age divisions‚ and we won three out of six games. This weekend I have another big tournament here in Coronado. At least

” I asked. “Why?” […] “We could be the first then (120-121).” > Dana is excited and very confident that she is going to be able to get off the streets. It gives all three of them something to look forward to and it teaches each of them a little bit of responsibility. Given these points it obviously shows that Dana has learned to be optimistic throughout her tough journey. Another quality Dana learns is trust. Before the supreme ordeal Dana is very closed off and untrusting‚ but afterwards she

My Nine Lives. Over the course of my long life (or lives depending on how you look at it) I have been known by many names. And not all of them translate exactly. My latest and last one is Gracen. I do not know how old I am‚ nor do I really care. All that matters is that I get two square meals a day and a warm bed at night. An occasional pet behind the ears is nice too. It’s times like this‚ late at night in my bed‚ when I reminisce back to where it all began. It began 17 years ago‚ on a crisp fall

Base-2 digits [Straight Binary] BCD [Binary-Coded Decimal] binary-coded decimal (BCD) - class of binary encodings of decimal numbers In byte-oriented systems (i.e. most modern computers)‚ the term uncompressed BCD usually implies a full byte for each digit (often including a sign)‚ whereas packed BCD

and Correction 1. Types of Errors Whenever bits flow from one point to another‚ they are subject to unpredictable changes because of interference. This interference can change the shape of the signal. In a single-bit error‚ a 0 is changed to a 1 or a 1 to a 0. The term single-bit error means that only 1 bit of a given data unit (such as a byte‚ character‚ or packet) is changed from 1 to 0 or from 0 to 1. The term burst error means that 2 or more bits in the data unit have changed from 1 to 0 or

DCN VIVA QUESTIONS 1. What do you mean by data communication? Ans: It is the exchange of data between two devices via some form of transmission medium such as wire cable. The communicating system must be part of a communication system made up of a combination of hardware and software. The effectiveness of a data communication system depends on three fundamental characteristics: delivery‚ accuracy and timeliness. 2. What is simplex? Ans: It is the mode of communication between two devices in which

errors through interference by changing one or more bits. There are two types of errors‚ in single bit errors‚ a 0 may be turned into a 1 or vice versa. In real world conditions‚ most interference introduce burst errors where two or more bits are switched from a 0 to a 1 and vice versa. Types of Errors 1. Single-Bit Error – a single bit is switched from a 0 to a 1 or a 1 to a 0 2. Burst Error – one or more bits are flipped. Single Bit Error 0 | 0 | 0 | 0 | 0 | 0 | 1 | 0 | 0 | 0 |
