Answer:
B. TCP ensures messages can be reliably transmitted across the Internet.
D. TCP must account for the fact that packets may not arrive at a destination computer in the intended order
Explanation:
TCP or transmission control protocol is a connection oriented protocol that divides a packet to segments, and reliably sends them to their destination.
TCP is a layer 4 (transport layer) protocol in the OSI network model. Its packets data unit, PDU, is called segment.
For TCP connection to be successful, a three way handshake must be established between the client and server.
When a connection is established, tcp sends the packets in sequenced segments to the destination through various routes, the source receives acknowledgement for segments received by the destination and the source resend segment that were lost. In the destination, the TCP arranges the segments to its proper sequence.
Identify an attribute selector used to select an element based on its class value.
Answer:
elem.class is the correct answer for the above question.
Explanation:
In CSS(cascading style sheet), When a user wants to use any property for any attribute and if there are multiple attributes on which he wants to apply the same property then he needs to use the attribute selector based on class.
Just, for example, suppose there is a two image in an HTML document and both need to fill the green color then the user needs to give the same class to both div and use that class property in a CSS to define the green color which can be applied on the image.To use the class property in a CSS, a user needs to define like---
elem.class (where 'elem' is the name of the tag ('img' tag in the above example) and class is the name of the defined class(which is same on the bothe 'img' tag)).The Question asked about the attribute selector of class in CSS and the answer is elem.class, which is defined above.You need to place a wireless access point in your two-story building.

Suppose that you purchase a wireless router and connect it to your cable modem. Also, suppose that your ISP dynamically assigns your connected device (your wireless router) one IP address. Also suppose that you have six PCs at home that use 802.11 to wirelessly connect to your wireless router. How are IP addresses assigned to the six PCs? Does your wireless router use NAT? Why or why not?
Answer:
The six PCs are assigned private IP addresses via Dynamic Host Configuration Protocol (DHCP)
Yes, the wireless router uses Network Address Translation.(NAT)
Explanation:
Network Address Translation. (NAT) allows a private unregistered network to connect to the internet using one IP address. It is the role of DHCP to assign the private IP addresses to all 6 PCs in the wireless LAN. NAT allows communication between these two different networks by translating the private IP address into a registered public IP address for internet access.
A data mart differs from a data warehouse in that: Group of answer choices it deals with a particular component or functional area of the business. data mart users do not have the data management expertise of data warehouse employees. Both it has a smaller database and it deals with a particular component or functional area of the business All of these it has a smaller database.
Answer:
A Data Warehouse is a corporate database that integrates purified information from the various sources in the organization. This information must be homogeneous and reliable, it is stored in a way that allows its analysis from many different perspectives, and that it is in turn of the optimal response times. For this, the information is highly denormalized and modeled in a way quite different from transactional systems, mainly the star models (star scheme) and snowflake (snowflake scheme) that we will study later.
A Data Warehouse is much more than what we have commented so far. According to Bill Inmon it is characterized by being:
Theme-oriented: data is organized by topics to facilitate user understanding, so that all data related to the same element of real life is linked together. For example, all customer data can be consolidated in the same table, all product data in another, and so on.
Integrated: the data must be integrated into a consistent structure, eliminating the inconsistencies involved between the various operational systems. The information is structured in various levels of detail to suit the needs of users. Some of the most common inconsistencies that we usually find are: in nomenclature, in units of measure, in date formats, multiple tables with similar information (for example, having several applications in the company, each with customer tables) .
Historical (time variant): the data, which may vary over time, must remain reflected in such a way that these changes are consulted and the reality that was at the time they were stored is not altered, thus avoiding the problem that occurs in the operational systems, that specifically only the state of the present business activity. A Data Warehouse must save the different values that take a variable over time. For example, if a client has lived in three different cities, he must specify the period he lived in each of them and associate the facts (sales, returns, incidents, etc.) that occurred at any time to the city in which He lived when they occurred, and did not associate all historical facts with the city in which he currently lives. If a customer, during all the time we have been selling has gone through three civil states (single, married and divorced) we must know what marital status he had at the time we made each of the sales.

When a policy setting in Computer Configuration and User Configuration in the same GPO conflict, the Computer Configuration policy setting takes precedence. True or False?
Answer:
True
Explanation:
Computer Configuration policy applied first. This happens when the Computer system boots up. Then the user policy is applied when the user logs on. This takes place when the user object is in the same organizational unit.
So Computer Config policy setting takes precedence. User configurations is applied to local users only while computer configuration is applied to the machine itself. First the Computer GPO is applied and then the User GPO. Loopback processing in replace mode enforces the Computer GPO over the user GPO.
One of the advantages of off-the-shelf software is that ________________. a. the software contains important features, thus eliminating the need for future modification and customization b. b. an organization does not have to pay for features that are not required and never used
Answer:
One of the advantages of off-the-shelf software is that the initial cost is lower because the software firm can spread the development costs over many customers.

Since off-the self software can be used by multiple customers, its initial cost is lower.
Example of off-the-shelf software are Salesforce CRM, Linux operating system, MySQL database, Microsoft Office, anti-virus programs.
Which type of drawer has three dispensing modes: single-dose, multi-dose, and matrix?
A. Matrix Half-height smart
B. CUBIE Full-height smart
C. CUBIE MiniDrawer Bin
Answer:
CUBIE MiniDrawer Bin
Explanation:
MiniDrawers comes in two configurations, and each fitting comes in one drawerslot. The MiniDrawer (1-6) comes with the most primary pocket dimensions. And we have the 18-tray MiniDrawer (1-8) comes with another dimensions in its basic form. You will in fact find various pocket dimensions like 1,2,3,4,6,12, and these comes within the 18-tray and 6-tray MiniDrawers. And they come in all the dispensing modes mentioned in the question. Hence, the above answer. The answer is clear from the options as well, and since it has the matrix mode as well apart from single dose mode and multi dose mode.
The drawer with three dispensing modes: single-dose, multi-dose, and matrix, is the CUBIE MiniDrawer Bin (option C). These modes provide flexibility in dispensing medications efficiently.
If you're looking for a drawer with three dispensing modes: single-dose, multi-dose, and matrix, the correct type is the CUBIE MiniDrawer Bin.(option C)These dispensing modes allow for various ways to manage and dispense medications in a medical setting with flexibility and efficiency. For example, the single-dose mode dispenses one unit at a time, the multi-dose mode allows multiple units, and the matrix mode provides a grid structure to dispense items from specific locations within the drawer.A 'array palindrome' is an array which, when its elements are reversed, remains the same (i.e., the elements of the array are same when scanned forward or backward) Write a recursive, bool-valued function, isPalindrome, that accepts an integer -valued array , and the number of elements and returns whether the array is a palindrome.
An array is a palindrome if:
the array is empty (0 elements ) or contains only one element (which therefore is the same when reversed), or
the first and last elements of the array are the same, and the rest of the array (i.e., the second through next-to-last elements ) form a palindrome.
Answer:
This code is written in MATLAB.
function [result] = isPalindrome(array,length)
if length == 0 || length == 1 %if the array is empty or contains only one element, the array is a palindrome
result = 1;
else
for i = 1:length/2 %check all the elements forward and backward until the middle is reached
if array(i) ~= array(end+1-i)
result = 0;
return
end
end
result = 1;
end
Explanation: Please read the comments in the code. In MATLAB, Boolean values are 1 or 0 instead of True or False.

James, a system administrator, is tasked to update the BIOS and firmware of the computer in his organization. What are the reasons to update them?
Answer:
One reason to update BIOS and firmware is to ensure they support new hardware like CPU model or graphic card. In some cases, the updates can also resolve overheating issue or motherboard issue.
However, this is not always the case that we must update the BIOS every time there is a new release because the latest update may cause problem to existing system as well.
As a general rule, only when there are some problems with the existing BIOS and firmware, we are only required to update them.
Updating the BIOS and firmware of computers ensures enhanced security, improved compatibility with new hardware and software, and increased stability and performance, all of which are essential for maintaining an efficient and secure computing environment.
Explanation:James, a system administrator, is tasked with updating the BIOS and firmware of computers in his organization. There are several reasons to perform these updates:
Enhanced Security: Updates can include patches to protect against new vulnerabilities, helping to keep the organization's data safe.Improved Compatibility: Firmware updates may enable hardware to work better with new devices or software, ensuring smooth operations.Increased Stability and Performance: Bug fixes and improvements in the updates can lead to a more stable and efficient computing environment, which is crucial for productivity.Just as an operating system is essential for a computer's operations, keeping system firmware up-to-date ensures the infrastructure of the computers remains reliable, efficient, and sustainable, avoiding the costly disruptions that come with outdated or malfunctioning systems.
