A laptop gets recycled by an e-waste recycling company once it can't be used anymore. Which stage of the hardware lifecycle does this scenario belong to
Answer:
Retirement.
Explanation:
When a laptop gets recycled by an e-waste recycling company once it can't be used anymore. This belongs to the retirement stage of the hardware lifecycle.
Hardware lifecycle can be defined as the management of the total or overall useful life of an equipment or device, so as to maximize or enhance the benefits to be derived from its use.
The retirement stage of a hardware represents the stage where the hardware has reached the end of its life-cycle and as such can not be used to perform the task for which it was designed. It is at the retirement stage, that hardwares are written off as scraps and are to be replaced by another because they can't be used anymore, as well as disposal for recycling purposes.
If you were doing a regular expression inside a Linux command line, which special character on the keyboard would give you two possible matches using the example below: car ____ truck
Answer: car | truck
Explanation: The pipe (|) symbol used can be used in regular expression to simply imply OR. This means when used in between expression, can be used to search for all matches of the strings in which it stands in between. In the scenario above, If the pipe symbol is located in between the two strings, such as [ cars | trucks], the expression returns possible occurrence of the strings cars and trucks. It may also be used to locate and return the occurrences of more than 2 strings, such as; string1 | string2 | string3
Memory operations currently take 30% of execution time of program A. A new widget called a "cache" speeds up 80% of memory operations by a factor of 4. A second new widget called a "L2 cache" speeds up half of the remaining 20% by a factor of 2. What is the total speed up?
Answer:
The answer is "1.24"
Explanation:
Formula:
[tex]\bold {Speedup= \frac{1}{(1 - non-speedup-portion) +(Speed up portion 1)}+\frac{(speed up-portion \ 2)}{ speedup\ 2}+ ....}\\\\[/tex]Given value:
Operations in the memory = 30%
= 0.3
80% Memory [tex]= 0.3 \times 80\%[/tex]
[tex]=[/tex] [tex]\frac{(0.3 \times 80) }{100}[/tex]
[tex]= 0.24[/tex]
Now it takes 0.06 seconds, saved 0.18 seconds.
20% of the memory operations:
[tex]= 0.3 \times 20\% \\\\= \frac{(0.3 \times 20)}{100} \\\\= 0.06[/tex]
Half of the other 20% = 0.03
It takes 0.015 seconds now, saved 0.015 seconds, saved 0.195 seconds.
It takes 0.805 seconds in the 1 second.
[tex]Speedup = \frac{1} {0.7 + 0.3\times \frac{0.8}{4}} + 0.3\times0.2\times\frac{0.5}{2} + 0.3\times0.2\times0.5[/tex]
[tex]Speedup = 1.2422[/tex]

Proper pagination is required for the overall good performance of a domain in search results Pagination is extremely important in e-commerce and editorial websites It is important to have all sub-pages of a category being indexed rel=next and rel=prev attributes explain to Google which page in the chain comes next or appeared before it
Answer:
The wrong statement in this question is "It's important to have all sub-pages of a category being indexed".
Explanation:
In the given-question, the above choice is incorrect because all subpages in such a segment are not important to also be indexed, and the other correct choice can be defined as follows:
For both the total good performance of even an area in search engine results, acceptable pagination is required. rel = next and prev, values are an attribute, that describes its page throughout the chain next to it and originally shown by Google.

A computer retail store has 15 personal computers in stock. A buyer wants to purchase 3 of them. Unknown to either the retail store or the buyer, 3 of the computers in stock have defective hard drives. Assume that the computers are selected at random.
(a) In how many different ways can the 4 computers be chosen?
(b) What is the probability that exactly one of the computers will be defective?
(c) What is the probability that at least one of the computers selected is defective?
Answer:
a. 1365 ways
b. Probability = 0.4096
c. Probability = 0.5904
Explanation:
Given
PCs = 15
Purchase = 3
Solving (a): Ways to select 4 computers out of 15, we make use of Combination formula as follows;
[tex]^nC_r = \frac{n!}{(n-r)!r!}[/tex]
Where [tex]n = 15\ and\ r = 4[/tex]
[tex]^{15}C_4 = \frac{15!}{(15-4)!4!}[/tex]
[tex]^{15}C_4 = \frac{15!}{11!4!}[/tex]
[tex]^{15}C_4 = \frac{15 * 14 * 13 * 12 * 11!}{11! * 4 * 3 * 2 * 1}[/tex]
[tex]^{15}C_4 = \frac{15 * 14 * 13 * 12}{4 * 3 * 2 * 1}[/tex]
[tex]^{15}C_4 = \frac{32760}{24}[/tex]
[tex]^{15}C_4 = 1365[/tex]
Hence, there are 1365 ways
Solving (b): The probability that exactly 1 will be defective (from the selected 4)
First, we calculate the probability of a PC being defective (p) and probability of a PC not being defective (q)
From the given parameters; 3 out of 15 is detective;
So;
[tex]p = 3/15[/tex]
[tex]p = 0.2[/tex]
[tex]q = 1 - p[/tex]
[tex]q = 1 - 0.2[/tex]
[tex]q = 0.8[/tex]
Solving further using binomial;
[tex](p + q)^n = p^n + ^nC_1p^{n-1}q + ^nC_2p^{n-2}q^2 + .....+q^n[/tex]
Where n = 4
For the probability that exactly 1 out of 4 will be defective, we make use of
[tex]Probability = ^nC_3pq^3[/tex]
Substitute 4 for n, 0.2 for p and 0.8 for q
[tex]Probability = ^4C_3 * 0.2 * 0.8^3[/tex]
[tex]Probability = \frac{4!}{3!1!} * 0.2 * 0.8^3[/tex]
[tex]Probability = 4 * 0.2 * 0.8^3[/tex]
[tex]Probability = 0.4096[/tex]
Solving (c): Probability that at least one is defective;
In probability, opposite probability sums to 1;
Hence;
Probability that at least one is defective + Probability that at none is defective = 1
Probability that none is defective is calculated as thus;
[tex]Probability = q^n[/tex]
Substitute 4 for n and 0.8 for q
[tex]Probability = 0.8^4[/tex]
[tex]Probability = 0.4096[/tex]
Substitute 0.4096 for Probability that at none is defective
Probability that at least one is defective + 0.4096= 1
Collect Like Terms
Probability = 1 - 0.4096
Probability = 0.5904

A Transmission Control Protocol (TCP) connection is established and two devices ensure that they're speaking the same protocol. What has occured?
A. Three-way handshake
B. Two-way handshake
C. Handshake
D. Four-way handshake
Answer:
The correct option is;
A. Three-way handshake
Explanation:
For establishment of connection within Transmission Control Protocol, (T. C. P.), involves a three-way way handshake. Prior to attempting a server connection, the server to which connection is sought passively opens a port by listening at the port. Upon establishment of passive open, active open by the client can then be initiated by the client. A connection establishment requires a three-way handshake as follows;
1. The client sends a SYN to the server
2. The server responds by sending a SYN-ACK
3. The client further responds sending ACK back to the server.
