Microprocessor Systems: Architecture and Components
Microprocessor System
A microprocessor system is the core of a computer. It is formed by a microprocessor: an integrated circuit that contains all the elements of the Central Processing Unit (CPU). Its functions are:
- Executes arithmetic instructions contained in the programs.
- Performs arithmetic and logical operations necessary for data processing.
- Centralizes control of the machine and exchanges data with main memory.
There are 4 different models of Microprocessors: Intelligence, ANP, and AIM.

Types of Communications
If a link between two nodes can be selected for communication in both directions (but alternatively), the link is bidirectional. If it is set in one direction and under the terms of a node, it will be one-way (incoming or outgoing).
- If a user node wants to communicate with another user and it also belongs to the node, the switching system has to make the connection of both. This communication is called local communication.
- If the user wishes to establish communication with another

Python Programming: Examples and Tips for INFO2000 Midterm
General Python Tips:
- Loops: Use
for i in range(start, stop, step):for iteration. - Lists:
my_list = [1, 2, 3], access elements withmy_list[index]. - Dictionaries:
my_dict = {'key': 'value'}, access withmy_dict['key']. - Functions: Use
def function_name(parameters): return valueto define. - Importing Libraries: Use
import random,import math. - Printing Debugging Info: Use
print(variable). - String Manipulation:
.upper(),.lower(),.strip(),.split(),.join(). - File Handling:
open('filename.txt', 'r')to read,open(
Understanding Computer Hardware and Software Components
Understanding Computer Hardware and Software
Data is the set of scientific and technical knowledge that enables the automatic processing of information. The term comes from the union of two words, referring to computers and their components:
Hardware and Software
A computer is composed of two separate, but closely related, parts:
- Hardware: Consists of the physical elements of the computer. It’s essentially made of electronic components that provide the necessary support for the interpretation and execution
