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:
O(n^2)
Explanation:
The number of elements in the array X is proportional to the algorithm E runs time:
For one element (i=1) -> O(1)
For two elements (i=2) -> O(2)
.
.
.
For n elements (i=n) -> O(n)
If the array has n elements the algorithm D will call the algorithm E n times, so we have a maximum time of n times n, therefore the worst-case running time of D is O(n^2)
Answer:
B) ERP systems
Explanation:
ERP which means Enterprise Resource Planning is a software that uses a centralized database, it helps to hasten business processes thereby reducing the use of manual labour. Some of the integrated software modules which it provides are:
*Finance, Accounting.
*Human resource.
*Manufacturing and production.
*Sales and marketing.
The ERP system does not really need the total involvement of a human because it has a database where information stored is used in the daily execution of tasks, it can also be used to measure the productivity and profitability of the business.
Answer:
painter = {'name' : "Vincent van Gogh", 'artworks': ["The Starry Night","Irises","The Potato Eaters"],'bornDate': "March 30, 1853", 'eyeColor': "July 29, 1890", 'diedDate': "July 29, 1890"} #this is a code which holds the questions defined value in a painter variable.
Explanation:
- The above question wants to declare a variable that is in the form of a key and value pair.
- The above question states to define name, artworks,eyeColor, and dieddate as a key and the other is defined as a value.
- when a user wants to access the whole dictionary then he can do with the help of the painter variable.
- But when he wants to access the value of any particular key, then he can do it with the help of the key name as "painter[keyname]".
