Answer: Parallel Array

Explanation:

Multiple arrays can be grouped together within a structure which is known as parallel array. Here the arrays are related by a common entry such as ith element in a arrays is related to the ith element  of the other array.

The answer is a Parallel Array. Because Parallel Arrays use the same subscript to connect entries between arrays.

<h2>Further Explanation </h2>

Computing is all activities that use computers to manage, process, and communicate information. Computing also includes the development of hardware and software. Computing is an important and integral component of modern industrial technology. The main computing disciplines include computer engineering, software engineering, computer science, information systems, and information technology.

In computing, Array of Structures (AoS), Structure Array (SoA) and Array of Structures of Array (AoSoA) refer to various ways to arrange the order of records in memory, related to interleaving, and that is interesting in SIMD and SIMT programming.

Array structure s (or SoA) is a layout that separates elements from records (or 'structs' in the C programming language) into one parallel array per field.

The array s (or AoS) structure is the opposite (and more conventional) layout, where data for different fields are interrelated. This is often more intuitive and is supported directly by most programming languages.

Array of Structures of Array s (or AoSoA) is a hybrid approach between previous layouts, where data for different fields are entered using tiles or blocks of the same size as the SIMD vector size. This is often less intuitive but can achieve memory throughput from the SoA approach while being more friendly to locality cache and loading the modern processor port architecture.

Artist 52 [7]

Answer:

The LC-3 (Little Computer 3) is an ISA definition for a 16-bit computer. Its architecture includes physical memory mapped I/O via a keyboard and display; TRAPs to the operating system for handling service calls; conditional branches on N, Z, and P condition codes; a subroutine call/return mechanism; a minimal set of operation instructions (ADD, AND, and NOT); and various addressing modes for loads and stores (direct, indirect, Base+offset, PC-relative, and an immediate mode for loading effective addresses). Programs written in LC-3 assembler execute out of a 65536 word memory space. All references to memory, from loading instructions to loading and storing register values, pass through the get Mem Adr() function. The hardware/software function of Project 5 is to translate virtual addresses to physical addresses in a restricted memory space. The following is the default, pass-through, MMU code for all memory references by the LC-3 simulator.

unsigned short int get Mem Adr(int va, int rwFlg)

{

unsigned short int pa;

// Warning: Use of system calls that can cause context switches may result in address translation failure

// You should only need to use gittid() once which has already been called for you below. No other syscalls

// are necessary.

TCB* tcb = get TCB();

int task RPT = tcb [gettid()].RPT;

pa = va;

// turn off virtual addressing for system RAM

if (va < 0x3000) return &memory[va];

return &memory[pa];

} // end get MemAdr

Simple OS, Tasks, and the LC-3 Simulator

We introduce into our simple-os a new task that is an lc3 Task. An lc3 Task is a running LC-3 simulator that executes an LC-3 program loaded into the LC-3 memory. The memory for the LC-3 simulator, however, is a single global array. This single global array for memory means that alllc3 Tasks created by the shell use the same memory for their programs. As all LC-3 programs start at address 0x3000 in LC-3, each task overwrites another tasks LC-3 program when the scheduler swaps task. The LC-3 simulator (lc3 Task) invokes the SWAP command every several LC-3 instruction cycles. This swap invocation means the scheduler is going to be swapping LC-3 tasks before the tasks actually complete execution so over writing another LC-3 task's memory in the LC-3 simulator is not a good thing.

You are going to implement virtual memory for the LC-3 simulator so up to 32 LC-3 tasks can be active in the LC-3 simulator memory without corrupting each others data. To implement the virtual memory, we have routed all accesses to LC-3 memory through a get Mem Adr function that is the MMU for the LC-3 simulator. In essence, we now have a single LC-3 simulator with a single unified global memory array yet we provide multi-tasking in the simulator for up to 32 LC-3 programs running in their own private address space using virtual memory.

We are implementing a two level page table for the virtual memory in this programming task. A two level table relies on referring to two page tables both indexed by separate page numbers to complete an address translation from a virtual to a physical address. The first table is referred to as the root page table or RPT for short. The root page table is a fixed static table that always resides in memory. There is exactly one RPT per LC-3 task. Always.

The memory layout for the LC=3 simulator including the system (kernel) area that is always resident and non-paged (i.e., no virtual address translation).

The two figures try to illustrate the situation. The lower figure below demonstrates the use of the two level page table. The RPT resident in non-virtual memory is first referenced to get the address of the second level user page table or (UPT) for short. The right figure in purple and green illustrates the memory layout more precisely. Anything below the address 0x3000 is considered non-virtual. The address space is not paged. The memory in the region 0x2400 through 0x3000 is reserved for the RPTs for up to thirty-two LC-3 tasks. These tables are again always present in memory and are not paged. Accessing any RPT does not require any type of address translation.

The addresses that reside above 0x3000 require an address translation. The memory area is in the virtual address space of the program. This virtual address space means that a UPT belonging to any given task is accessed using a virtual address. You must use the RPT in the system memory to keep track of the correct physical address for the UPT location. Once you have the physical address of the UPT you can complete the address translation by finding the data frame and combining it with the page offset to arrive at your final absolute physical address.

In a school 50% of the students are younger than 10, 1/20 are 10 years old and 1/10 are older than 10 but younger than 12, the r
Zielflug [23.3K]

Answer: 10 students

Explanation:

Students younger than 10 = 50%

Students that are 10years old = 1/20 = 1/20 × 100 = 5%

Students that are older than 10 but younger than 12 = 1/10= 1/10 × 100 = 10%

Students that are 12 years or older

= 100% - (50% + 5% + 10%)

= 100% - 65%

= 35%

This means that 35% of the students are 12 years or older and we've been given the number as 70.

Let's say the total number of students is x. Therefore,

35% of x = 70

0.35 × x = 70

0.35x = 70

x = 70/0.35

x = 200

The total number of students is 200.

Therefore, the number of students that are 10years will be:

= 1/20 × 200

= 10 students

Therefore, 10 students are 10 years.

Consider the following code:
Phoenix [80]

Answer:

customers += newCustomer;

Explanation:

The operator += expands into + and assignment. The assignment is not overloaded so the required code is

customers += newCustomer;

This expands into

customers = customers + newCustomer;

The overloaded + operator is called for the right expression. This returns a `CustomerList`, which is then assigned through the = operator to `customers`.
