You need to update your router settings, so you log into the administration panel, whose Internet Protocol (IP) address is 192.168.0.1. Which IP version is this
Answer:
IPv4
Explanation:
An IP address is an acronym for internet protocol address and it can be defined as a unique number assigned to a computer or other network devices, so as to differentiate each device from one another in an active network system. Thus, an IP address is typically used to uniquely identify each computer or network devices connected to the internet or network.
In Computer networking, IP address are classified into two (2) main categories and these are;
1. Local (internal) IP address.
2. Global (external) IP address.
Also, the internet protocol (IP) address comprises of two (2) versions and these are;
I. Internet protocol version 4 (IPv4): this is the first and original version of the internet protocol which was introduced in 1983 using the Advanced Research Projects Agency Network (ARPANET). An example of an IPv4 address is 192.168.1.0.
II. Internet protocol version 6 (IPv6): it is the modified (latest) version of the IPv4 address system and as such can accommodate more addresses or nodes. An example of an IPv6 is 2001:db8:1234:1:0:567:8:1.
Hence, Internet protocol version 6 (IPv6) was developed and introduced to replace the previous version (IPv4); Internet protocol version 4. The best statement which describes a benefit of IPv6 over IPv4 is that, Internet protocol version 6 (IPv6) eliminates the use of hierarchy in addressing, making addresses easier to use because the size of the routing table is smaller (reduced) and as such making routing with IPv6 to be more efficient.
In this scenario, you need to update your router settings, so you log into the administration panel, whose Internet Protocol (IP) address is 192.168.0.1. Thus, this is the IPv4 IP version.

7. Which cipher is based on the clues of the physical factors, rather than the hardware or a software cryptosystem
Answer:
The concealment cipher.
Explanation:
A concealment cipher also known as null cipher can be defined as an obsolete encryption format that typically involves the mixture of plaintext with non-cipher elements. This ultimately implies that, the plaintext is hidden in another message through encryption.
The concealment cipher is based on the clues of the physical factors, rather than the hardware or a software cryptosystem.
Basically, the concealment cipher is solely dependent on the clues of the physical factors that mainly affects the sender and receiver in a communication system.
What the five types of initiatives that are necessary when putting together and implementing an IT strategy
Answer:
Pre-implementation
Planning
Execution
Completion
Control
Explanation:
The pre-implementation stage speaks volumes on the breakdown of the implementation stages and how it is being formulated. It shows a stepwise identification of important implementation carriers and the responsibility of the IT organization. Their focus is to determine the content and human resources that are required to implement the strategy being formulated.
The purpose of the planning implementation stage is to plan and agree on specific goals by considering all stakeholders. There is also a need to set deadlines, time-to-time evaluation, and effective coordination of the stakeholders.
The execution phase enforces the implementation plan. As the name implies, it builds a comprehensive plan by focusing on the target group to maintain and ensure a structural and systematically conducted work environment.
The completion phase includes all actions necessary to bring out the results within the organizzation. Initially, there is a need to agree on the dimension of the IT strategy, the time dimension, and the detailed dimension.
The last phase which is the control deals with the logic of setting appropriate quantitative and qualitative control measures so as to allows continuous implementation control and navigation implementation control.
Jim wants to enlarge a black-and-white photograph with a warm-black tone. What type of black-and-white paper emulsion should Jim use for this
process?
A chlorobromide
B. bromide
C. chloride
D platinum
Answer:
A. Chlorobromide
Explanation:
I took the test and got it right. (Plato)
The type of black-and-white paper emulsion should be used by Jim is chlorobromide. Thus, option (A) is correct.
What is emulsion?A sort of colloid called an emulsion is created by mixing two liquids that wouldn't typically mix. A dispersion of the other liquid is present in one liquid in an emulsion.
Emulsions frequently occur in foods like egg yolk, butter, and mayonnaise. Emulsification is the process of combining liquids to create an emulsion.
According to the above scenario, Jim wishes to expand a warm-toned black-and-white photograph. For this purpose, he should use chlorobromide for black-and-white paper emulsion.
Paper covered with a chemical compound that is light-sensitive, which is inferred as photographic paper. When exposed to light, it captures the latent image.

If a folder exists on an NTFS partition, which permission is needed by a user who needs to set security permissions on the folder?
Answer:
Full control.
Explanation:
An access control can be defined as a security technique use for determining whether an individual has the minimum requirements or credentials to access or view resources on a computer by ensuring that they are who they claim to be.
Simply stated, access control is the process of verifying the identity of an individual or electronic device. Authentication work based on the principle (framework) of matching an incoming request from a user or electronic device to a set of uniquely defined credentials.
Basically, authentication and authorization is used in access control, to ensure a user is truly who he or she claims to be, as well as confirm that an electronic device is valid through the process of verification
Hence, an access control list primarily is composed of a set of permissions and operations associated with a NTFS file such as full control, read only, write, read and execute and modify.
Hence, if a folder exists on a new technology file system (NTFS) partition, the permission which is needed by a user who needs to set security permissions on the folder is full control.
Define the summary function, which takes as arguments a database (dict) and a dict of current stock prices. It returns a dictionary (dict or defaultdict) whose keys are client names (str) whose associated values are 2-tuples: the first index is a dictionary (dict or defaultdict) whose keys are stock names (str) and values are the number of shares (int) the client owns. The second index is the amount of money (int) the portfolio is worth (the sum of the number of shares of each stock multiplied by its current price). Assume each client starts with no shares of any stocks, and if a client owns 0 shares of a stock, the stock should not appear in the client’s dictionary. Recall positive numbers are a purchase of the stock and negative numbers a sale of the stock. E.g., if db is the database above, calling summary(db, {'IBM':65, 'Intel':60, 'Dell':55, 'Apple':70}) would return

How would you pause a program for 5 seconds?
pause(3)
time.pause(5)
time.sleep(5)
sleep(3)
Answer:
time.sleep(5)
Explanation:
For Python, not sure what program your teacher is asking about.
The Python time sleep function is used to delay a program's execution. To stop the running of the program for a certain amount of time in seconds, we can use the sleep function in Python. Thus, option C is correct.
What time sleep () in Python?Python comes with built-in functionality for sleeping your program. The sleep() function in the time module allows you to pause the caller thread's execution for however long you choose.
The current thread's execution can be paused for a given amount of time in milliseconds by using the sleep() function. The millisecond argument value cannot be negative. If not, it raises an Illegal Argument Exception.
The current thread is put on hold for a set amount of time via sleep. This is an effective way to give other threads of an application or other apps that could be executing on a computer system access to processor time.
Therefore, time.sleep(5) pause a program for 5 seconds.
