Answer:
Modern (i.e 386 and beyond) x86 processors have eight 32-bit general purpose registers, as depicted in Figure 1. The register names are mostly historical. For example, EAX used to be called the accumulator since it was used by a number of arithmetic operations, and ECX was known as the counter since it was used to hold a loop index. Whereas most of the registers have lost their special purposes in the modern instruction set, by convention, two are reserved for special purposes — the stack pointer (ESP) and the base pointer (EBP).
For the EAX, EBX, ECX, and EDX registers, subsections may be used. For example, the least significant 2 bytes of EAX can be treated as a 16-bit register called AX. The least significant byte of AX can be used as a single 8-bit register called AL, while the most significant byte of AX can be used as a single 8-bit register called AH. These names refer to the same physical register. When a two-byte quantity is placed into DX, the update affects the value of DH, DL, and EDX. These sub-registers are mainly hold-overs from older, 16-bit versions of the instruction set. However, they are sometimes convenient when dealing with data that are smaller than 32-bits (e.g. 1-byte ASCII characters).
When referring to registers in assembly language, the names are not case-sensitive. For example, the names EAX and eax refer to the same register.

Answer:
mobility and broad reach
Explanation:
The two major characteristics of mobile computing are:
Mobility: It basically refers to the portability. Mobility means that users can carry their mobile device wherever they go. This facilitates real-time communication with other devices. Users can take a mobile device anywhere and can contact with other devices and systems via a wireless network for example a user, wherever he happens to be, can log in to his email account to check his emails using his mobile phone.
Broad Reach: It basically means that the mobile device users can be reached at any time. This means that the users of an open mobile device can be instantaneously contacted. Having an open mobile device means that it can be reached by or connected to other mobile networks. However mobile users also have options to restrict specific messages or calls.
Answer:
I will write the code in C++ and JAVA
Explanation:
<h2>
JAVA CODE</h2>
public class Main
{ public static void main(String[] args) {
// displays Gershwin,George
System.out.println("Gershwin,George"); } }
<h2>
C++ Code:</h2>
#include <iostream>
using namespace std;
int main()
{ cout<<"Gershwin,George";
}
// displays last name Gershwin followed by , followed by first name George
//displays Gershwin,George as output.
Explanation:
Exterior gateway protocol are the routing protocols that are used on the internet for exchanging routing information among the autonomous system. These autonomous systems can be gateway protocol, vector routing protocol.
Answer:
Motivation? The search problem.
Sorting algorithms: insertion sort, shellsort, heapsort, mergesort, quicksort, bubblesort
At the very least, "general purpose" sorting algorithms require O(n log n) comparisons
