Explanation:
Sites like Zillow get input about house prices from a database and provide nice summaries for readers. Write a program with two inputs, current price and last month's price (both integers). Then, output a summary listing the price, the change since last month, and the estimated monthly mortgage computed as (currentPrice * 0.051) / 12 (Note: Output directly. Do not store in a variable.). Ex: If the input is: 200000 210000 the output is:
This house is $200000.
The change is $-10000 since last month.
The estimated monthly mortgage is $850.0.
Answer:
The program in Python is as follows:
currentPrice = int(input("Current: "))
lastMonth = int(input("Last Month: "))
print("The house is $",currentPrice)
print("The change is $",(currentPrice-lastMonth),"since last month")
print("The estimated monthly mortgage is $",(currentPrice * 0.051) / 12)
Explanation:
Get input for current price
currentPrice = int(input("Current: "))
Get input for last month price
lastMonth = int(input("Last Month: "))
Print current price
print("The house is $",currentPrice)
Print change since last month
print("The change is $",(currentPrice-lastMonth),"since last month")
Print mortgage
print("The estimated monthly mortgage is $",(currentPrice * 0.051) / 12)
A hard disk drive has 10 surfaces, 10240 tracks per surface, and 512 sectors per track. Sector size is 4 KB. The drive head traverses 1280 track/ms and the spindle spins at 5400 r.p.m.
(a) What is the total capacity of hard disk drive (in GB)?
(b) What is the physical address of the sector whose logical block address (LBA) is 2312349 ?
(c) What is the longest time needed to read an arbitrary sector located anywhere on the disk?
(a) The total capacity of the hard disk drive is 10 surfaces * 10240 tracks/surface * 512 sectors/track * 4 KB/sector = 204800 MB = 200 GB.
What is the physical address of the sector?(b) The physical address of the sector with LBA 2312349 is calculated as: surface = LBA/(trackssectors) = 2312349/(10240512) = 4; track = (LBA%(trackssectors))/sectors = (2312349%(10240512))/512 = 2512; sector = LBA%sectors = 2312349%512 = 85.
So, it's (4, 2512, 85).
(c) The longest time to read an arbitrary sector is from the outermost track to the innermost track (10240 tracks) at 1280 track/ms speed, plus one full rotation at 5400 RPM: (10240/1280) ms + (60/5400) s = 8 ms + 11.11 ms = 19.11 ms.

What characteristics are common among operating systems
The characteristics are common among operating systems are User Interface,Memory Management,File System,Process Management,Device Management,Security and Networking.
Operating systems share several common characteristics regardless of their specific implementation or purpose. These characteristics are fundamental to their functionality and enable them to manage computer hardware and software effectively.
1. User Interface: Operating systems provide a user interface that allows users to interact with the computer system. This can be in the form of a command line interface (CLI) or a graphical user interface (GUI).
2. Memory Management: Operating systems handle memory allocation and deallocation to ensure efficient utilization of system resources. They manage virtual memory, cache, and provide memory protection to prevent unauthorized access.
3. File System: Operating systems organize and manage files and directories on storage devices. They provide methods for file creation, deletion, and manipulation, as well as file access control and security.
4. Process Management: Operating systems handle the execution and scheduling of processes or tasks. They allocate system resources, such as CPU time and memory, and ensure fair and efficient utilization among different processes.
5. Device Management: Operating systems control and manage peripheral devices such as printers, keyboards, and network interfaces. They provide device drivers and protocols for communication between the hardware and software.
6. Security: Operating systems implement security measures to protect the system and user data from unauthorized access, viruses, and other threats.
This includes user authentication, access control mechanisms, and encryption.
7. Networking: Operating systems facilitate network communication by providing networking protocols and services. They enable applications to connect and exchange data over local and wide-area networks.
These characteristics form the foundation of operating systems and enable them to provide a stable and efficient environment for users and applications to run on a computer system.

What is the output of the following code snippet if the variable named cost contains 100? if cost < 70 or cost > 150 : discount = 0.8 * cost else : discount = cost print("Your cost is ", discount)
Answer:
The output is: Your cost is 100
Explanation:
Given
The above code snippet
and
\(cost = 100\)
Required
Determine the output of the code
if cost < 70 or cost > 150
The above condition checks if cost is less than 70 or cost is greater than 150
This condition is false because 100 is neither less than 70 nor is it greater than 150
So, the else statement will be executed.
discount = cost
Which means
discount = 100
So, the print instruction will print: Your cost is 100
