Answer:

While the Internet was evolving and creating a way for organizations to connect to each other and the world, another revolution was taking place inside organizations. The proliferation of personal computers inside organizations led to the need to share resources such as printers, scanners, and data. Organizations solved this problem through the creation of local area networks (LANs), which allowed computers to connect to each other and to peripherals. These same networks also allowed personal computers to hook up to legacy mainframe computers.

An LAN is (by definition) a local network, usually operating in the same building or on the same campus. When an organization needed to provide a network over a wider area (with locations in different cities or states, for example), they would build a wide area network (WAN).

CLIENT-SERVER

The personal computer originally was used as a stand-alone computing device. A program was installed on the computer and then used to do word processing or number crunching. However, with the advent of networking and local area networks, computers could work together to solve problems. Higher-end computers were installed as servers, and users on the local network could run applications and share information among departments and organizations. This is called client-server computing.

INTRANET

Just as organizations set up web sites to provide global access to information about their business, they also set up internal web pages to provide information about the organization to the employees. This internal set of web pages is called an intranet. Web pages on the intranet are not accessible to those outside the company; in fact, those pages would come up as “not found” if an employee tried to access them from outside the company’s network.

EXTRANET

Sometimes an organization wants to be able to collaborate with its customers or suppliers while at the same time maintaining the security of being inside its own network. In cases like this a company may want to create an extranet, which is a part of the company’s network that can be made available securely to those outside of the company. Extranets can be used to allow customers to log in and check the status of their orders, or for suppliers to check their customers’ inventory levels.

Sometimes, an organization will need to allow someone who is not located physically within its internal network to gain access. This access can be provided by a virtual private network (VPN). VPNs will be discussed further in the chapter 6 (on information security).

Convert the following hexadecimal numbers to decimal: (a) FF (b) F0A2 (c) 0F100 (d) 100
Hatshy [7]

Answer:

a) 255

b) 61602

c)

d)

Explanation:

You need to understand the decimal equivalent of hexadecimal numbers, <em>from 0 to 9 numbers are represented the same way, from 10 to 15 we use the alphabet, meaning 10 equals A in hexadecimal base, 11-B, 12-C, 13-D, 14-E, and 15-F.</em>

For your first exercise you'll enumerate the number's positions fromright to lef begining with 0:

a.               F   F

position    1    0

Now you'll multiply your hexadecimal number (using the decimal equivalent for your letters) for the base (16) elevated to the number of the position:

F*16^{0}=15*1=15\\F*16^{1}=15*16=240

Finally, you'll add your results:

240+15=255

FF=255

b.             F  0  A  2

position   3  2  1   0

2*16^{0}=2*1=2\\A*16^{1}=10*16=160\\0*16^{2}=0*256=0\\F*16^{3}=16*4096=61440\\\\2+160+0+61440=61602\\

F0A2=61602

c.             F  1  0  0

position   3  2  1   0

0*16^{0}=0*1=0\\0*16^{1}=0*16=0\\1*16^{2}=1*256=256\\F*16^{3}=16*4096=61440\\0+0+256+61440=61696\\

0F100=61696

d.              1  0  0

position  2  1   0

0*16^{0}=0*1=0\\0*16^{1}=0*16=0\\1*16^{2}=1*256=256\\\\0+0+256=256\\

100=256

I hope you find this information useful! Good luck!

Otrada [13]

Answer:

no_of_shares = int(input("Enter the number of shares: "))

purchase_price = float(input("Enter the purchase price of the stock: "))

sale_price = float(input("Enter the sale price of the stock: "))

total_stock_price = purchase_price*no_of_shares

total_spend_on_buying = total_stock_price + (0.03*total_stock_price)

total_sale_price = sale_price*no_of_shares

commission_while_selling = total_sale_price*0.03

net_gain_or_loss = total_sale_price - (total_spend_on_buying + commission_while_selling)

if(net_gain_or_loss<0):

print("After the transaction, you lost {} dollars".format(abs(net_gain_or_loss)))

else:

print("After the transaction, you made {} dollars".format(abs(net_gain_or_loss)))
