Convert the following numbers. (Please show all steps; no marks will be awarded if no steps are shown) [1.5 x 4 = 6 marks]

katen-ka-za [31]

Answer:

i. 10210212

ii. 100 101 001 in BASE 2

iii. 46.4631

iv. 12.453125

Explanation:

i. Converting to base 10 we get

= 10 x 162 + 13 x 161 + 9 x 160 = 2777

Converting to base 10 we get =

2777/3 = 925 with remainder 2

925/3 = 308 with remainder 1

308/3 = 102 with remainder 2

102/3 = 34 with remainder 0

34/3 = 11 with remainder 1

11/3 = 3 with remainder 2

3/3 = 1 with remainder 0

1/3 = 0 with remainder 1

Hence the Answer is 10210212

ii. = Octal is taken in pair of 3 bits , Writing binary of each number in 3 bits we get = 100 101 001 in BASE 2

iii. = 1 x 52 + 2 x 51 + 3 x 50 + 3 x 5-1 = 38.6 in decimal

Converting to Octal we get

38 /8 = 4 with remainder 6

4 /8 = 0 with remainder 4

.6 x 8 = 4.8

.8 x 8 = 6.4

46.4631

iv. = 1x 81 + 4 x 80 + 3 x 8-1 + 5 x 8-2 = 12.453125

_____ transparency exists when the end user or programmer must specify the database fragment names but does not need to specify

madam [21]

Answer:

The correct answer to the following question will be "Local mapping".

Explanation:

A data independence standard in global DBMSs where questions can be constructed without understanding the local formats. Knowledge of quotas of pieces and components is however important.
With the transparency of local mapping, the user wants to determine both fragment location and name of data items, keeping in mind any replication that may occur.
This is clearly a more complicated and time-consuming question for all the users to answer than the first. A program that only offers it the amount of transparency would be unlikely to be satisfactory to later part-users.

Therefore, "Local mapping" is the right answer.

Write the correct word to complete the sentence:

spayn [35]

Answer:

Legend

Explanation:

In English language, a legend can be defined as a traditional narrative or story that is written about a particular person or past events and it's likely to either be a myth or historical facts. Thus, a legend is sometimes an unrealistic story or narration that describe a particular person or an extraordinary event that occured in the past. Also, it's a story about a particular figure, past human events or actions whose origin is unknown, unproven and undocumented in real history

Additionally, the word "legend" was derived from the Latin word "legendus" which simply means something which should be read.

Hence, the most appropriate word to complete the sentence is a legend because there are no proven and documented or written records about how Bolster the Giant terrorised the people of Cornwall. Thus, the complete mythical sentence is then written as;

"According to legend, Bolster the Giant terrorised the people of Cornwall."
