Core Graphic Design Concepts and Terminology

Vector Graphics and File Types

• Vector allows for resizing without loss in quality.
• Vector graphics are smaller in file size.

• PNG file type (Portable Network Graphics).
• SVG (Scalable Vector Graphics).

Digital Asset Sourcing

• He found the images online, but they were in the public domain.
• The team member created the images himself.

The whole is greater than the sum of the parts.

Typography and Text Handling

• Kerning: The spacing between specific pairs of characters.
• Leading: The distance between each line of text.

Font Classifications

• Script
• Decorative
• Serif
• Sans Serif

Text Overflow

Even though it's not visible, the excess text is still in the bounding area, and a small plus (+) symbol is displayed at the bottom of the...

Bit stuffing and destuffing are crucial techniques used in data link layer protocols to ensure reliable data transmission. They prevent sequences of data bits from being misinterpreted as control characters or flags, especially when the data itself contains patterns identical to these control sequences.

What is Bit Stuffing?

Bit stuffing is the process of adding one or more extra bits into a data stream to break up a sequence of identical bits that might otherwise be misinterpreted as a control signal. For example, in protocols like HDLC, a flag sequence (01111110) is used to mark the beginning and end of a frame. To prevent the actual data from containing this sequence, a '0' bit is stuffed after every five consecutive '1's in the data stream....

1. Half-Adder Truth Table and Circuit

For a two single-bit input, draw the truth table and corresponding circuit for the half-adder.

Truth Table

Where A and B are the input values, C is the output carry, and Σ is the sum.

(The question also requires a circuit diagram, which typically consists of an XOR gate for the Sum and an AND gate for the Carry.)

2. MIPS Overflow Handling Options

MIPS provides the following instruction options to handle overflow:

• add, addi, sub: These instructions cause an exception on overflow.
• addu, addui, subu: These instructions do not cause an exception on overflow.

3. MIPS Signed Addition Overflow Check

To avoid exceptions when performing signed addition, one can use addu and check for overflow...

Pascal Movie Database Management

This document details several procedures written in Pascal for managing a movie database. The database is stored in a file of records, where each record represents a movie.

Data Structure

The code defines a pelicula (movie) record with the following fields:

• codigo: integer (Movie ID)
• genero: string (Genre)
• nombre: string (Title)
• duracion: integer (Duration)
• director: string (Director)
• copias: integer (Number of Copies)
• precio: real (Price)

A constant valoralto is defined as 9999, used as a sentinel value.

And the file is defined as:

maestro= file of pelicula ;

Procedures

leerp(var p: pelicula)

Reads movie data from the input (keyboard) and stores it in the pelicula record p. It reads the codigo first. If it's not equal to...

Structural Design Patterns

Decorator - Adds additional functionality to a class

Adapter - 'adapts' one interface for a class into one that the client expects

Façade - creates a simplified interface from an existing one

Flyweight - A high quantity of objects share common properties to save space.

Bridge - decouples an abstraction from its implementation so that the two can vary independently.

Behavioral Design Patterns

Chain of Responsibility - Linked list of handlers

Command - Enables all the info for a request to be contained within a single object.

Interpreter - Developing domain specific languages

Iterator - Sequentially access elements of an aggregate object.

Mediator - Removes the need for classes to communicate with each other directly.

Tarea 1: Registrar Kilometraje por Práctica Insertada

Requisito: Crear un TRIGGER donde, cada vez que se inserta una práctica a un alumno, se deben sumar 50 KMS al vehículo que tiene asignado el alumno.

Definición del Trigger PRAC (Inserción de Práctica)

CREATE TRIGGER PRAC

    SELECT @CODAL = A.CodMon#
    FROM ALUMNO A
    INNER JOIN INSERTED I ON A.CodAl# = I.CodAl#;

    -- Nota: La siguiente selección es redundante o lógicamente incorrecta en este contexto:
