Active Directory (AD)
Explanation:
The centralized directory database that contains user account information and security for the entire group of computers in a network.
The service that manages the process of allowing a user to sign on to the network from any computer and access resources is authentication, involving account policies and possibly VPNs.
In a domain, the process of allowing a user to sign on to the network from any computer on the network and get access to resources is managed by authentication, account policies, and often involves the use of a Virtual Private Network (VPN).
These services ensure that users are authenticated first and then given access to the organizational resources which they are authorized to access, while maintaining the security of their devices and credentials.
In the context of Microsoft Windows, the account policies can include Password Policies, Account Lockout Policies, and Kerberos Policies, which are a subset of the domain's security policy stored in the Active Directory.

I hope it will help you!Discuss the textbook's recommendations for improving business-IT communication. Provide examples from your own experience to support your ideas.
Answer:
Make the importance of effective communicationWork with HR to develop new Skills expectations and rolesMaking Oral ReportsUsing the TelephoneGive Direction and FeedbackExplanation:
Good communication skill is the most important skill for having a good relationship with business and that is why nowadays companies are making it must-have skill for every IT employee. They are also including it into performance appraisals so that way employees are giving it a topmost priorityCompanies are creating the jobs having titles such as "technology relationship manager", "IT Business Analyst" and "business technology specialist" where the titles suggest that the main focus of such titles is IT-Business relationship. One another way companies are trying to adopt is moving IT employees temporary for some time in business so that they can learn the business and enhance the relationship with them. You will need to make oral reports to other staff, such as the executive chef or restaurant manager. For example, you might have to report on the condition of some equipment or explain your actions regarding a problem with a restaurant supplier. You will also need to make oral reports to people who work under you, such as apprentices or salad preparation staff. For example, you might have to explain the preparation of a new menu item. An effective oral report has the same parts as an effective written report, namely an introduction, a body (or explanation), and a conclusion. Communicating on the telephone can be more difficult than speaking in person because many of the non-verbal cues are missing. When dealing with guests and other outsiders, it is particularly important to create a good first impression of your business. This first impression is created almost solely by your voice. For example, if you pick up the phone and bark “Yo” into the receiver, the caller is likely to be put off by your offhand manner and tone of voice. The caller may wonder whether he or she has reached the right number.A form of oral report that you will have to make if you supervise other people feedback on others’ performance. Feedback can be constructive or destructive. As these words imply, only constructive feedback serves any useful purpose. Take an example where the apprentice under your supervision is making pastries. Destructive feedback would be, “Are you stupid or something? The oven needs to be preheated before you put the pastries in to bake!” Do not use blaming words or indulge in name calling (“You are so…”). When people feel blamed, they often tune out of the discussion and do not hear your positive suggestions for improvement.Question 8 :You are currently editing a Web document in a GUI HTML editor.

Each device with a NIC contains a unique identifier, known as a(n) ___ address, which distinguishes it from any other network-connected device in the world.
Answer:
Media Access Control (MAC)
Explanation:
Every device that has a network interface card (NIC) contains a unique identifier called MAC address which differentiates it from other networking devices all over the world. It is also called a physical or hardware address. MAC addresses are integrated into the NIC of networking devices.
MAC addresses are a 12-digit hexadecimal number usually separated by a colon.
Note that a 12-digit hexadecimal implies also that it is a 6-byte (or 48-bit) number.
An example of a MAC address (in hexadecimal) is as follows;
00:0A:D8:12:E5:13
Final answer:
Each device with a NIC has a unique MAC address which is a hardware identifier that ensures correct data packet delivery. It is distinct from other identifiers such as IP addresses, which can change; the MAC address usually remains constant.
Explanation:
Each device with a Network Interface Card (NIC) contains a unique identifier, known as a MAC address, which distinguishes it from any other network-connected device in the world. The MAC address, which stands for Media Access Control address, is a hardware identifier that uniquely identifies each device on a network. MAC addresses are used for various network technologies, including Ethernet and WiFi.
When a device, such as a computer, smartphone, or printer, attempts to connect to a network, its NIC provides the MAC address to the network to establish the connection. The unicity of the MAC address ensures that each device's data packets are delivered correctly in the midst of network traffic. Internet Protocol (IP) addresses are often discussed in conjunction with MAC addresses, but while IP addresses can change, for example when a device moves between networks, the MAC address typically remains the same unless it is spoofed or altered by the user.
What problem can occur when a programmer fails to specify the base case or to reduce the size of the problem in a way that terminates the recursive process?
Answer:
Inifinite loop will occur.
Explanation:
For instance the code block below will result in an infinite loop:
int prev (x){
Return prev (x-1);
}
The base case is what determine when the function should stop calling itself; if it is absent, infinite loop will occur.
In the above code, a base case of when x = 0 or x = 1 should have been added to avoid the infinite loop.
For wired network cards that get their IP addresses through DHCP, what can be set manually?
APIPA
Default gateway
DHCP server
DNS server
For wired network cards using DHCP for IP addresses, you can manually set the Option B) Default Gateway and Option D) DNS Server.
For wired network cards that get their IP addresses through DHCP, certain settings can still be configured manually. These include the Default Gateway and the DNS Server. These options allow you to ensure the network card can correctly route traffic and resolve domain names even if it is obtaining its IP address automatically.
Default Gateway: This is the IP address of the router or gateway that connects the local network to other networks, most often the internet. By setting this manually, you ensure that the network card knows where to send requests that are outside the local network.
DNS Server: This is the IP address of the server that resolves domain names (like www.example.com) into IP addresses. Setting this manually can be useful if you prefer to use a specific DNS server, such as Goo-gle's Public DNS or another trusted DNS provider.
Other options mentioned, like DHCP Server and APIPA (Automatic Private IP Addressing), typically do not require manual configuration in this context. APIPA is a fallback for when DHCP is unavailable, automatically assigning an IP address from a specific range.

If an unsorted list of numbers is to be searched for a particular number only once, which of the following is more efficient (faster)? Group of answer choices Do not sort the list. Do a bisection search. Sort the list first, then do a bisection search. Do not sort the list. Do a linear search. Sort the list first, then do a linear search.
Answer:
Sort the list first, then do a bisection search
Explanation:
In bisection search method, we divide the array of numbers in two equal parts. Then we check that the number is exist in first half or second half. It is necessary to perform this operation that array should sorted. This is the fast searching algorithm as compared to Linear search. In linear search Algorithm we have to check every element in the array until we find the required number. The bisection search method is faster as compare to linear search. This follows following steps top complete the operation of searching.
Sort the arrayDivide the total array in two equal partsCheck that the required number that we want to search is in first half or second halfIf the number is found in first half then second half of array will be discarded.Then repeat step 2 and 3 until not found the required element.ListenListen with ReadSpeakerAn administrator working on a Windows Server 2016 Server Core installation needs to disable DHCP on all interfaces on the server.

Answer:
its was B,C,E
Explanation:
i know becase i took it
An HTML element is characterized by its start and end tags, the contents it surrounds, the ability to contain nested elements, and the use of attributes which include a keyword and additional information in quotes. Attributes can sometimes be required for the element's proper functionality and accessibility.
Explanation:The characteristics that represent an HTML element include start tag, end tag, and the contents they surround. HTML elements can also include nested elements within themselves to create complex structures. Additionally, elements feature attributes, which are used to provide additional information about the element. An attribute in HTML consists of a keyword followed by an equals sign and additional information enclosed in quotes. Some HTML elements may have certain required attributes that need to be included for the element to function correctly or convey the desired property.
For example, the <a> tag for creating links requires the 'href' attribute to specify the URL, like <a href="https://example.com">Visit Example</a>. The 'alt' attribute for <img> tags, which provides alternative text for an image, is another example of a required attribute. Such attributes play a crucial role in accessibility and proper functionality of web content.
Between which zones and a DMZ should firewalls be placed? Choose two answers.
Remote
Segregated
Internal
External
Answer:
DMZ is placed between Internal and External separated by firewalls.
Explanation:
DMZ is demilitarized Zone, that is used to enhance the security feature of the local area network of the organization of firm from other networks exist on the internet. Few organizations need more security from the users that tries to access the resources and information from outside the organization. These users may steal some confidential information or tries to hack the network.
There are three major zones in these types of network, Internal, DMZ and External zones. Internal Zones is separated by DMZ with the help of firewall. The traffic that tries to access the internal network from DMZ checked through this security firewall. The external zone is also separated through a firewall from DMZ, used to monitor the external traffic tries to access the the network.
