Answer:
sed '/march/{d;}' birthdays.txt > result .txt
Explanation:
sed syntax is basically:
sed '/expression/{command;command;...;}' inputfile > outputfile
First, for the expression part, we use /march/ to match all lines containing that string. Then for the command part, we only use {d} command to delete every matching line found.The third part contains the input file to process, I have named it birthdays.txt, but it could have been any other file needed.Finally "> result .txt" makes the script output to be saved into a file named result.txtdifferences between formula and function as used in spreadsheet

Write a program that asks the user for the name of a text file. The program should display the first 10 lines of the file on the screen. If the file has fewer than 10 lines, the entire file should be displayed along with a message indicating the entire file has been displayed.
Answer:
Written in Python
filenm = input("File name: ")
myfile = open(filenm+".txt")
for i in range(10):
line = myfile.readline()
print(line)
print("End of file")
Explanation:
This line prompts user for file name
filenm = input("File name: ")
This line creates an instance of the file
myfile = open(filenm+".txt")
This line iterates through the 10 lines
for i in range(10):
This line reads the line
line = myfile.readline()
This line prints each line
print(line)
This line prints a message indicating that all possible lines have been printed
print("End of file")

A boundary marks the inside and outside of a system and sets the system apart from its environment.
A. True
B. False
Answer:
True
Explanation:
The system boundary can be regarded as a conceptual line that demacate
the system that is under study from 'everything else'. which is the environment. The environment consist of things that can influence the system but not part of the system. when the system is small , its boundary will be sharper. Some Large systems usually have multiple boundaries.boundary can as well be regarded as the point of contact which gives room for meeting between a system its environment , it is also point subsystems meet each other. It should be noted that boundary marks the inside and outside of a system and sets the system apart from its environment.

Convert the following by showing all the steps necessary
a) (1001111) 2 = ( ) 10
b) (11000001) 2 = ( ) 16
c) (E16) 16 = ( ) 10
d) (56) 10 = ( ) 16
e) (63) 10 = ( ) 2
Answer:
The answers are:
[tex]a) (1001111)_2 = (79 )_{10}\\b) (11000001)_2 = (C1 )_{16}\\c) (E16)_{16} = ( 3606)_{10}\\d) (56)_{10} = (38 )_{16}\\e) (63)_{10}= (111111 )_2[/tex]
Explanation:
a. (1001111) 2 = ( ) 10
In order to convert a base 2 number to base 10 number system the place values are used.
the procedure is as follows:
[tex](1001111)_2\\=(1*2^6)+(0*2^5)+(0*2^4)+(1*2^3)+(1*2^2)+(1*2^1)+(1*2^0)\\=(1*64)+(0*32)+(0*16)+(1*8)+(1*4)+(1*2)+(1*1)\\=64+0+0+8+4+2+1\\=79[/tex]
b) (11000001) 2 = ( ) 16
In order to convert a base 2 number into base 16, group of 4-bits are made starting from right to left
The groups from the given number are:
1100 0001
Then the groups are changed in to decimal/hexa
So,
[tex](1100)_2 = (1*2^3)+(1*2^2)+(0*2^1)+(0*2^0)\\=(1*8)+(1*4)+(0*2)+(0*1)\\=8+4+0+0=12=C\\\\0001=1[/tex]
Writing in the same order in which groups were:
[tex](C1)_{16}[/tex]
c) (E16) 16 = ( ) 10
[tex](E16)_{16}\\=(E*16^2)+(1*16^1)+(6*16^0)\\=(E*256)+(1*16)+(6*1)\\=3584+16+6\\=3606[/tex]
d) (56) 10 = ( ) 16
Dividing by 16 and noting remainders
16 56
3 - 8
So,
The number in base 16 is 38
e) (63) 10 = ( ) 2
Dividing by 2
2 63
2 31 - 1
2 15 - 1
2 7 - 1
2 3 - 1
1 - 1
So the number after converting in base 2 is:
111111
Hence,
The answers are:
[tex]a) (1001111)_2 = (79 )_{10}\\b) (11000001)_2 = (C1 )_{16}\\c) (E16)_{16} = ( 3606)_{10}\\d) (56)_{10} = (38 )_{16}\\e) (63)_{10}= (111111 )_2[/tex]

Answer: what?
Explanation:
The type of wireless access that uses a modem to connect to cell towers is called ___
broadband.
Answer:
What are the Wireless Broadband Technologies?
What are the Wireless Broadband Technologies?
Wireless broadband services are similar to wired broadband in that they connect to an internet backbone usually a fiber-optic trunk; however they don’t use cables to connect to the last mile or business/residences. Instead they use Wireless Fidelity (Wi-Fi) connections or radio waves. A computer or mobile device has a wireless adapter that translates data into a radio signal and transmits the signal using an antenna. A wireless router receives the signal, decodes it and then sends it to the Internet through a wired Ethernet connection.
Fixed wireless is a type of high-speed Internet access where connections to service providers use radio signals rather than cables. Fixed wireless offers connections speeds between 1 and 10 mbps and use transmission towers similar to cell phone towers that communicate to a resident’s transceiver equipment that, as the name implies is fixed at the premise. The transceiver equipment communicates with the providers’ ground stations.
Wireless fidelity (Wi-Fi) is a fixed, short-range technology that is often used in combination with DSL, fixed wireless, fiber, or cable modem service to connect devices within a home or business to the Internet using a radio link between the location and the service provider’s facility. Wi-Fi service can be available in your home or at community locations (airports, coffee shops, schools, businesses, etc.) and are often called “hotspots.” A Wi-Fi network uses radio waves, similar to two-way radio communications. A computer has a wireless adapter that translates data into a radio signal and transmits it using an antenna. A router receives the signal, decodes it, and then sends the information to the Internet using a physical connection, usually via an Ethernet cable, a cable that carries the broadband signal between the modem, router, computer, and other wired Internet capable devices.
Mobile Wireless (3G, 4G)
Mobile wireless is high-speed wireless broadband connection that is accessible from random locations. The locations depend on the provider’s cellular towers and monthly service plans. Many technologies make up wireless networks, but no matter the technology or acronyms you read or hear, mobile wireless networks are radio systems.
Mobile wireless services are continually being upgraded to provide data transmission speeds considered to be broadband. The faster mobile wireless networks are referred to as 3G or 4G.The “G” stands for “generation,” meaning 3rd and 4th generation or the evolution of broadband cellular networks; supposedly, each generation provides a faster more secure wireless network. A mobile wireless service requires a base station that is connected to a high capacity landline data transmission network to reach the Internet. In other words, it’s never wired OR wireless; ultimately, it has to be both. Wireless broadband in common usage means that the so-called “last mile” connection to the user is done via radio signals from a tower to a cell phone or other wireless devices (e.g., a tablet).
Long Term Evolution (LTE)
LTE is a 4G technology provides increased peak data rates, reduced latency, scalable bandwidth capacity than 4G predecessors. LTE can manage multi-cast and broadcast streams and handle quick-moving mobile phones. It uses an IP-based network architecture that allows for seamless handovers for voice and data to older model cell towers.
Satellite
Satellite broadband is sometimes the only option available to users in very rural or sparsely populated areas. Like telephone and television services, satellites orbiting the earth provide necessary links for broadband. With satellite service, you must have a clear view of the southern sky. Satellite service can be disrupted by weather conditions and changes in line of sight to the orbiting satellite. Satellite may have a higher monthly service charge than other broadband options and the need to purchase more home or business equipment compared to the other options. Because satellites are located a significant distance from customers, there are issues of “latency” and therefore a noticeable time lag between sending and receiving data by the end customer.
Downstream and upstream speeds for satellite broadband depend on several factors, including the provider and service package purchased the consumer’s line of sight to the orbiting satellite, and the weather. Satellite speeds may be slower than DSL and cable modem, but they can be about 10 times faster than the download speed with dial-up Internet access. Service can be disrupted in extreme weather conditions.

Explanation:
Memory compression is a useful alternative to paging:_______.
a. when the compression algorithm is can achieve the best possible compression ratio.
b. when the system has slow magnetic disks but not faster SSDs.
c. when the speed of the compression algorithm fastest.
d. even when the system has faster SSDs.
Answer:
d. even when the system has faster SSDs.
Explanation:
Given that Memory compression and Paging are both means of performing memory management in different ways.
However, Memory compression is a useful alternative to paging "even when the system has faster SSDs."
This is because Memory compression enhances the productivity of Radom Access Memory, RAM, which in turn increases the performance level of a computer.
Also, paging requires consistent writing on Disks, which has been found to degrade disks most especially solid-state drives, SSDs.

When you read in data from a file using the read() method the data is supplied to Python in the form of:
A. A list of Strings
B. A String
C. A list of lists
D. Raw ASCII values
Answer:
B. A String
Explanation:
Remember, there are other methods or ways to read data from a file such as readlines(), and the for ... in loop method.
However, if you read in data from a file using the read () method the data would be supplied to Python in the form of a String (or single String). This is the case because a String supports only characters, unlike lists that could contain all the data types.
Using the read() method in python is used to read in files such as text files, csv and other file types. The read() method will render the read in data as as a string.
In general, the read in data from the file is supplied in the form of a string, however, depending on the version of python which is being used, the string type may vary. When using python 2, the data is supplied as a bytestring while the data is supplied a unicode string in python 3.Hence, the read() method renders data as a string.
