Answer:
def extract_title(file):
import re
a =''
with open(file,'r') as file:
for line in file:
a += line
m = re.search("^(TITLE)(.*?)(JOURNAL)", a, re.M + re.S)
print(m.groups()[1])
extract_title('new.txt')
Explanation:
The programming language used is python 3.
The function is first defined and the regular expression module is imported.
A variable is initialized to an empty string that will hold the content of the GenBank formatted file.
The file is opened and every line in the file is assigned to the string variable. The WITH statement allows files to be closed automatically.
Regular expression is used to capture all the files between TITLE and JOURNAL in a group.
The group is printed and the function is called.
I have attached a picture of the code in action.
Answer:
Explanation:
The arithmetic logic unit (ALU) performs mathematical, logical, and decision operations. It can be divided into the arithmetic unit (responsible for addition, subtraction, multiplication and division). And logic unit (responsible for comparing, selecting, matching and merging different data or information). The power and efficiency of the CPU depends on the design of the ALU.
Next up is the control unit (CU) which directs all the processor’s operations. It’s where the CPU reads and interprets requests from memory and transforms them into a series of signals (binary). Then it sends the operation to various parts of the laptop as instructed. The CU calls the ALU to perform the necessary calculations. It also coordinates all input/output devices to transfer or receive instructions.
The main job of the memory unit is to store data or instructions and intermediate results. It’s divided into primary memory and secondary memory to supply data to other units of the CPU. It allows the CPU to perform functions requested by programs like the operating system without having to ask RAM.
Another element of the CPU not depicted in the diagram is transistors. To carry out calculations, binary information (ones and zeros) is stored in these microscopic switches. They control the flow of electricity depending on whether the switch is ON or OFF. Signals turn off and on different combinations of transistors to perform calculations. A very thin silicon chip can contain several hundred million transistors.
The stage that precedes the implementation stage of SDLC is <u>testing</u> and it involves checking the functionality of the system.
System design involves the process of determining an overall system architecture, which typically comprises the following:
- Physical processing components.
Generally, there are seven (7) main stages in the systems development life cycle (SDLC) model and these include:
1. Planning.
2. Analysis.
3. Design.
4. Development.
5. Testing.
6. Implementation.
7. Maintenance.
From the above, we can deduce that the stage which precedes the implementation stage of SDLC is testing.
During the testing stage of SDLC, a quality assurance (QA) expert checks the system to determine whether or not it is functioning properly before it is deployed for operation, which is where the system can be used.

Data sharing, maintaining security
<u>Explanation:</u>
Kristian is a cybersecurity professional. She is writing a book called The Door Toward Cybersecurity. Organizations should avoid any data <u>sharing or exchange</u> while servers are transmitting information. This will help organizations keep the information intact and maintain <u>security.</u> If any info or data shared when the servers are transmitting the info, then it may lead to the loss of security, and the information gets leaked. So it must be avoided to share while transmission of info using the servers.
