It depends on the specific make and model of your car and phone, as well as the settings and capabilities of the specific applications you are using.
Explanation in Detail:
In general, if you have an Android phone and you are using Assistant Drive mode, you may be able to use your car's display screen to view maps and navigation information. However, this will depend on whether your car's display screen is compatible with your phone and whether the navigation app you are using is compatible with your car's display screen.
For example, some newer models of cars have built-in Android Auto functionality, which allows you to use your car's display screen to access certain apps and features on your Android phone. If your car has this capability and you are using an Android Auto-compatible navigation app, you may be able to view maps and navigation information on your car's display screen.
Similarly, if you are using a navigation app that is compatible with Ap*ple CarPlay (such as Go*ogle Maps or Waze), you may be able to view maps and navigation information on your car's display screen if your car has Apple CarPlay functionality.
It is also worth noting that some cars have their own built-in navigation systems that can be used independently of your phone. In this case, you may not need to use your phone's navigation app at all.

(d) [1] How many bits are needed for the Physical Page Number (PPN)? (Hint: use part (c)) (e) [1] How big in bytes does a page table entry (PTE) need to be to hold a single PPN plus a valid bit? (f) [1] How big would a flat page table be for a single process, assuming PTEs are the size computed in part (e)? (g) [10] Why does the answer above suggest that a "flat page table" isn't going to work for a 64-bit system like this? Research the concept of a multi-level page table, and briefly define it here. Why could such a data structure be much smaller than a flat page table? (h) [4] Does a TLB miss always lead to a page fault? Why or why not?
We have 2^48 pages per person. The number of physical pages is 2^16.. 48 bits of VPN are mapped to 16 bits of PPN. The PTE size is 2B. The page table size is 2^49 B.
What are the steps to calculate pages per person, physical pages, VPN ,PTE size and the table size?We know that;
Virtual Address = 64bits
Virtual Address Space = 2^Virtual Address = 2^64B
Physical Address Space = 4GB = 4 X 2^30 B = 2^32 B
Physical Address = log_2(Physical Address Space ) = log_2(2^32)
= 32 * log_2(2) = 32 bits.
Page size = 64KB =2^16 B
a) No of Virtual Pages = Virutal Address Space/PageSize
= 2^64B / 2^16 B = 2^48
b) NoOfPhysicalPages = PhysicalAddressSpace/PageSize
= 2^32 B / 2^16 B = 2^16
c) VPN (in Bits) = log_2(NoOfVirtual Pages) = log_2(2^48) = 48
PPN(inBits)=log_2(NoOfPhysicalPages)= log_2(2^16) = 16
Thus 48 bits of VPN are mapped to 16 bits of PPN.
d) PTE( Page Table Entry) holds the Physical Page Number of given Virtual Page along with many information about the page.
PTEsize = PPN(inBits) = 16 bits = 2B
e) Flat page table is single level page table. A page table contains the Physical Page number for a given page number. It helps in the translation of Vitual Address to Physical Address.
PageTableSize = NoOfVirtualPages*PTEsize = 2^{48}*2B = 2^49
