Answer:
PC3 12800
Explanation:
The RAM which should Jessica purchase so that she can use a quad channel on her motherboard is the PC3 12800 because it supports 1600 MHz modules while the other RAMs such as PC4 24000, PC3 1600 and PC3 10600 does not support 1600 MHz modules so that's why Jessica shouldn't purchase any of these RAMs and prefer PC3 12800 over the others.
PC3 12800 is recommended as she has a motherboard can hold 16GB of RAM and has four slots. Moreover She also has two DDR3 DIMM modules that are labeled 1600 MHz.
A user calls to report that she is experiencing intermittent problems while accessing the wireless network form her laptop computer. While talking to her, you discover that she is trying to work form the break room two floors above the floor where she normally works.
Which of the following is the MOST likely cause of her connectivity problem?
• The user has not yet rebooted her laptop computer while at her new location.
• The user needs a new IP address because she is working on a different floor.
• The wireless network access point on the user's normal floor has failed.
• The user is out of the effective range of the wireless access point on her floor.
• The user has not yet logged off and back on to the network while at her new location.
Answer:
The user is out of the effective range of the wireless access point on her floor.
Explanation:
This user is obviously not close to the access point. As help desk, if a user ever calls to complain about slow speeds or intermittent connectivity while trying to access the network, the first question that you should ask them is how far out are they from the modem or the Access Point. The location between her and the access point might affect the performance of the wireless network. Since she is working from the break room that is two floors above the floor where she normally works, then this means that the walls and ceilings will act as an obstruction to the Wi-Fi signal. The number of Walls and other obstacles will obviously affect the range of the Wi-Fi and will limit the signal’s effectiveness. I will advise the user to go back to her initial working area or be within range to the access point.

Which of the following is not a component of the programming phase of facility construction? deciding what to build examining space, cost, and other criteria designing the facility with architects deciding what events will be held at the facility and addressing capacity and amenities issues deciding the number and location of food and beverage preparation and sales areas
The programming phase focuses on fundamental design and planning aspects of facility construction but does not typically include deciding which events will be held at the facility. It lays out foundational design elements like capacity and amenities, while event scheduling pertains to operational planning.
The component that is not a part of the programming phase in facility construction is 'deciding what events will be held at the facility'. Programming, as a part of the design process, focuses on gathering information about the project, such as site inventory, analysis, and understanding user needs, environmental conditions, and economic considerations. This phase includes activities like deciding what to build, examining space, cost and other criteria, and integrating findings into the design with architects. It specifically deals with the fundamental aspects of designing the facility, ensuring the design maintains a focus on elements like capacity and amenities to meet users' needs. However, decisions related to events pertain to operational planning, which is distinct from the initial construction programming.
Programming provides the critical foundation for later stages such as schematic design, design development, construction documentation, and construction administration. This early stage of planning helps lay out the essential frameworks and supports potential adaptability in design—not detailed operational planning such as event scheduling.

Use two variables k and total to write a for loop to compute the sum of the squares of the first 50 counting numbers, and store this value in total. Thus, your code should put 1*1 + 2*2 + 3*3 +... + 49*49 + 50*50 into total. Use no variables other than k and total.
Answer:
Following are the statement in the C++ Language
int total=0; // variable declaration
int k;// variable declaration
for(k=0;k<50;k++) // iterating the for loop
{
total=total+k*k;// perform operation and calculating square of 50 number
}
Explanation:
Following is the description of the statement
Declared a variable "total" and "k" of the "int" type initialized the total variable with the value 0. Iterating the for loop for calculating the squares of the first 50 counting numbers. So we will execute the loop less then 50 . In this loop, we counted the square of 50 number in the "total" variable.Give a recursive implementation for the function: def is_sorted(lst, low, high) This function is given a list of numbers, lst, as well as two indices: low and high (low ≤ high), which indicate the range of the indices for the elements that should to be considered. When called, the function should determine if the elements that are placed at the low, low+1, …, high positions, are in an (ascending) sorted order. That is, it should return True if-and-only-if lst[low] ≤ lst[low+1] ≤ … ≤ lst[high] For example, if lst = [1, 3, 6, 8, 12, 15, 31], the call is_sorted(lst, 0, 6), will return True. Implementation requirements: Your function should run in worst case linear time. That is, if n is the size of the range low, low+1, …, high, calling is_sorted(lst, low, high) will run in �(�). Note: Write your implementation.
Answer:
# recursive method to find if list is in ascending order
def is_sorted(list, low, high):
if low >= high: # if reached end of list
return True
if list[low] > list[low+1]: # if item at low is greater than low+1
return False # return false
return True and is_sorted(list, low+1, high) # or return True and recursion call to low+1
Explanation:
