Lesson 5 php operators
Download as pptx, pdf0 likes398 views
Operators in PHP are used to perform operations on variables and values. They are divided into arithmetic, assignment, comparison, increment/decrement, logical, string, array, and conditional assignment operators. PHP arithmetic operators perform common math operations, assignment operators write values to variables, and comparison operators compare two values.

The basic arithmetic operators are addition, subtraction, multiplication, and division. Comparison operators compare values, including equal, not equal, greater than, and less than. Assignment operators assign values to variables. Logical operators perform logical AND, OR, and NOT operations. Bitwise operators manipulate bits within a binary number. Membership operators test if a value is present within a sequence. Identity operators check if two values are the same type or object.

Common LAN topologies include bus, star, ring, switched, daisy chain, and hierarchical topologies. Bus topology is easy to implement but has limited cable length. Star topology is easy to manage and scale but a failure of the central device takes down the whole network. Ring topology provides better performance than bus but a single failure affects the whole network. WAN topologies include peer-to-peer, ring, star, full mesh, partial mesh, multi-tiered, and hybrid configurations with different tradeoffs around cost, performance, redundancy, and scalability.

It defines data, information, and databases. A database management system (DBMS) is introduced as a collection of programs that enables users to create and maintain a database by defining, constructing, manipulating, and sharing the data. A DBMS also protects the database and maintains it over time. Examples of database systems that store student and course information are provided to illustrate database concepts. Characteristics of the DBMS approach are compared to the traditional file system approach.
Lesson 3.2
Lesson 3.2MLG College of Learning, Inc A flowchart is a graphical representation of a process or system. This document provides flowcharts for troubleshooting various hardware issues, including hard drive boot problems, CPU/RAM/motherboard performance issues, video adapter/GPU/monitor problems, peripheral device failures, SCSI/SAS drive errors, and DVD/CD/Blu-ray recording issues. The flowcharts help diagnose common problems and their potential solutions.
Lesson 3.1
Lesson 3.1MLG College of Learning, Inc This document discusses common computer errors, including hardware errors like blank monitors, hard drive failures, and faulty keyboards or mice. It also covers software errors such as access denied, file not found, and out of memory issues. Specific error types like disk read errors, boot failures, freezing, and the blue screen of death are explained in more detail. The document emphasizes the importance of properly diagnosing errors to identify whether the issue is hardware or software related.
Lesson 1.6
Lesson 1.6MLG College of Learning, Inc Bootable media contains software that allows a computer to boot from a removable device like a USB flash drive. When booting, the computer performs self-checks, loads the BIOS which finds the boot loader on the hard drive, and then loads the operating system along with hardware drivers and any startup programs. Bootable USB flash drives provide an easy way to install operating systems without discs by creating a portable boot device.
Lesson 3.2
Lesson 3.2MLG College of Learning, Inc Computer troubleshooting is a systematic process used to locate the cause of faults in computer systems and resolve hardware and software issues. It involves following a logical process with steps like identifying the problem, establishing a probable cause, testing theories to determine the cause, developing a solution plan, verifying the system works, and documenting findings. Troubleshooting skills are developed over time through experience solving different problems. Common computer issues include failures of storage devices, motherboards, power supplies, CPUs, memory, displays, and more. Solutions may involve checking connections, updating drivers or BIOS, replacing faulty components, and ensuring proper cooling and power.

Diptera: The Two-Winged Wonders, The Fly Squad: Order Diptera.pptxArshad Shaikh Diptera, commonly known as flies, is a large and diverse order of insects that includes mosquitoes, midges, gnats, and horseflies. Characterized by a single pair of wings (hindwings are modified into balancing organs called halteres), Diptera are found in almost every environment and play important roles in ecosystems as pollinators, decomposers, and food sources. Some species, however, are significant pests and disease vectors, transmitting diseases like malaria, dengue, and Zika virus.

Hemiptera, commonly known as true bugs, is a large and diverse order of insects that includes cicadas, aphids, leafhoppers, and shield bugs. Characterized by their piercing-sucking mouthparts, Hemiptera feed on plant sap, other insects, or small animals. Many species are significant pests, while others are beneficial predators.
*Order Neuroptera:*
Neuroptera, also known as net-winged insects, is an order of insects that includes lacewings, antlions, and owlflies. Characterized by their delicate, net-like wing venation and large, often prominent eyes, Neuroptera are predators that feed on other insects, playing an important role in biological control. Many species have aquatic larvae, adding to their ecological diversity.

Lesson 5 php operators
- 1. Welcome to Computer Programmer 2 PHP Language – Lesson 5 Prepared By: Analyn G. Regaton
- 2. PHP Operators Operators are used to perform operations on variables and values. PHP divides the operators in the following groups: •Arithmetic operators •Assignment operators •Comparison operators •Increment/Decrement operators •Logical operators •String operators •Array operators •Conditional assignment operators
- 3. PHP Arithmetic Operators The PHP arithmetic operators are used with numeric values to perform common arithmetical operations, such as addition, subtraction, multiplication etc.
- 4. PHP Assignment Operators The PHP assignment operators are used with numeric values to write a value to a variable. The basic assignment operator in PHP is "=". It means that the left operand gets set to the value of the assignment expression on the right.
- 5. PHP Comparison Operators The PHP comparison operators are used to compare two values (number or string):
- 6. PHP Increment / Decrement Operators The PHP increment operators are used to increment a variable's value. The PHP decrement operators are used to decrement a variable's value.
- 7. PHP Logical Operators The PHP logical operators are used to combine conditional statements.
- 8. PHP String Operators PHP has two operators that are specially designed for strings.
- 9. PHP Array Operators The PHP array operators are used to compare arrays.
- 10. PHP Conditional Assignment Operators The PHP conditional assignment operators are used to set a value depending on conditions:
- 11. PHP Constants The end !
