In the SDLC's third phase, the way in which a proposed information system will deliver the general abilities described in the pr

kifflom [539]

Answer: Detailed

Explanation:

SDLC consist of 7 phases. They are:

1. Planning.

2. System analysis and requirement

3. Design:

4. Coding:

5. Testing:

6. Installation

7. Maintenance

Here we are talking of the third phase. In this phase it is the design phase which consist of high and low level design. Here the preliminary design is included in high level design where it describes the required hardware, software, network capabilities and the modelling of the interface. However the detailed design in low level design will implement the coding and will finding of any errors in the implemented design as described by the preliminary design.

Simora [160]

Answer:

The answer is " $\bold{Brand \ A \ (35, 350, 18.7) \ \ Brand \ B \ (35, 50, 7.07)}$ "

Explanation:

Calculating the mean for brand A:

$\to \bar{X_{A}}=\frac{10+60+50+30+40+20}{6} =\frac{210}{6}=35$

Calculating the Variance for brand A:

$\sigma_{A}^{2}=\frac{\left ( 10-35 \right )^{2}+\left ( 60-35 \right )^{2}+\left ( 50-35 \right )^{2}+\left ( 30-35 \right )^{2}+\left ( 40-35 \right )^{2}+\left ( 20-35 \right )^{2}}{5} \\\\$

$=\frac{\left ( -25 \right )^{2}+\left ( 25 \right )^{2}+\left ( 15\right )^{2}+\left ( -5 \right )^{2}+\left ( 5 \right )^{2}+\left ( 15 \right )^{2}}{5} \\\\ =\frac{625+ 625+225+25+25+225}{5} \\\\ =\frac{1750}{50}\\\\=350$

Calculating the Standard deviation:

$\sigma _{A}=\sqrt{\sigma _{A}^{2}}=18.7$

Calculating the Mean for brand B:

$\bar{X_{B}}=\frac{35+45+30+35+40+25}{6}=\frac{210}{6}=35$

Calculating the Variance for brand B:

$\sigma_{B} ^{2}=\frac{\left ( 35-35 \right )^{2}+\left ( 45-35 \right )^{2}+\left ( 30-35 \right )^{2}+\left ( 35-35 \right )^{2}+\left ( 40-35 \right )^{2}+\left ( 25-35 \right )^{2}}{5}$

$=\frac{\left ( 0 \right )^{2}+\left ( 10 \right )^{2}+\left ( -5 \right )^{2}+\left (0 \right )^{2}+\left ( 5 \right )^{2}+\left ( -10 \right )^{2}}{5}\\\\=\frac{0+100+25+0+25+100}{5}\\\\=\frac{100+25+25+100}{5}\\\\=\frac{250}{5}\\\\=50$

Calculating the Standard deviation:

$\sigma _{B}=\sqrt{\sigma _{B}^{2}}=7.07$

Mark each statement as true or false: a. PATA hard drives are older and slower than SATA hard drives. b. SATA1 is about 10 times

deff fn [24]

Answer:

The answer to this question can be described as follows:

a) True

b) False

c) False

d) False

e) False

f) True

Explanation:

In option a, PATA device is used to connect the hard drives into systems. Its title suggests, depends on parallel transmitting technology, contrasted to the compulsive-signaling tools.

In option b, SATA1 is a first-generation device, and SATA3 third generation, that's why it is wrong.

In option c and option d, both were wrong because RAID 0 and RAID 5 are Cloud computing software for storing data.

In option e, An internal SATA data cable with an eSATA port can not be used as an additional connection is provided by the eSATA port.

In option f, It is true because there are 7 pins in internal SATA.
