1862 : the Parkésine (Alexander Parkes )
Answer: 19th century
Explanation:
Plastic was invented by Alexander Parkes in Birmingham, England, with the name "Parkesin", a mixture of nitrocellulose, camphor and alcohol. At that time, rubber was used for materials to be shaped with molds instead of plastic. Parkes showed his invention to the world in 1862 at the Great International Fair. His invention won a bronze medal. Due to the high cost of rubber, Alexander Parkes' invention attracted great attention.
Possibly the largest number of different polymeric materials come under the plastic classification. Plastics are materials that have some structural rigidity under load, and are used in general-purpose applications.Polyethylene, polypropylene, poly(vinyl chloride), polystyrene, and the fluorocarbons, epoxies, phenolics, and polyesters may all be classified as plastics. They have a wide variety of combinations of properties.
Some plastics are very rigid and brittle (Figure 15.1, curve A). Others are flexible, exhibiting both elastic and plastic deformations when stressed, and sometimes experiencing considerable deformation before fractureThere are many different polymeric materials that are familiar to us and find a wide variety of applications; in fact, one way of classifying them is according to their enduse.
IT technicians are setting up a new file server for a school. Describe the benefits and
drawbacks of using a command line interface (CLI) rather than a graphical user interface
(GUI) to set up a new file server.
Answer:
The benefits of using the command line interface for setting up a file server are;
1) The command line interface (CLI) is faster than other interfaces and can easily handle tasks which are repeating such as creating folders for users on the server
2) The CLI requires less time for processing with the CPU, and it takes up less memory such that the file Server is not slowed down during the file setup process
3) The system resources required are few
The drawbacks are;
1) The CLI is confusing to those who are not exposed to programming as the commands the user needs to learn to before they can setup setup the new file server
2) The users needs to be very accurate in terms of spelling errors as that will lead to failure of the program, there are no spell check, and a mistype can lead to the entire coding process being restarted from the beginning

>What is the output of the following code:
list1 = [ 'cyber', 786 , 2.23, 'square', 70.2 ]
print (list1[1] )
Answer:
Given code output is "786".
Explanation:
Code:
list1 = [ 'cyber', 786 , 2.23, 'square', 70.2 ]#defining a list list1 that holds value in parameter
print (list1[1] )#use a print method that prints list index value
In the given code a list "list1" is declared that holds value in it and in the next step a print method is declared that prints the first index value of the list.

Write a structured algorithm that prompts the
user to input two numbers. The algorithm should
multiply both numbers and then prompt the
user to enter the answer. The algorithm should
compare the answer entered with that calculated
and output "correct answer" or "incorrect answer"
accordingly. At the start, input how many sums
will be done.
Answer:
Step 1 : Start
Step2 : Input first number, num1
Step3 : Input second number, num2
Step4 : product - - > num1 * num2 (product of num1 and num2)
Step5 : Input product, myanswer
Step6 : comparison - - - > correct or incorrect based on myanswer and product
Step6: print(comparison)
Step7: End
Explanation:
Algorithm is a sequence of instructions a computer is expected to follow to solve a particular problem.
Required :
Two inputs ; num1 and num2
Expected output
Algorithm :
Step 1 : Start
Step2 : Input first number, num1
Step3 : Input second number, num2
Step4 : product - - > num1 * num2 (product of num1 and num2)
Step5 : Input product, myanswer
Step6 : comparison - - - > correct or incorrect based on myanswer and product
Step6: print(comparison)
Step7: End
The two numbers to multiply are entered ; the product is calculated by the program ; the the user inputs his or her own expecteted product ;
Both are compared and the output of the comparison is displayed (either correct oe incorrect)

A _______ spans a geographic area like a city,is larger than a LAN and smaller than WAN
Answer:
metropolitan area network (MAN)
Explanation:
A local area network (LAN) refers to a group of personal computers (PCs) or terminals that are located within the same general area and connected by a common network cable (communication circuit), so that they can exchange information from one node of the network to another. A local area network (LAN) is typically used in small or limited areas such as a set of rooms, a single building, school, hospital, or a set of well-connected buildings.
On the other hand, a metropolitan area network (MAN) spans a geographic area like a city, is larger than a local area network (LAN) and smaller than wide area network (WAN).
Basically, a metropolitan area network (MAN) is formed by an aggregation of multiple local area network (LAN) that are interconnected using backbone provided by an internet service provider (ISP). A metropolitan area network (MAN) spans for about 5 kilometers to 50 kilometers in size.
