The troubleshooting process

The troubleshooting process - POST - Firmware Configuration (Post, Bios, Cmos and Uefl) - System boot process - Electrical Power Issues - CPU Architectures and Enhancement - RAID - Cables and External Connectors - Monitors - Hardware Upgrades - Specialized configuration - Responsibilities of a computer tech (most to least often) * Daily Troubleshooting * Periodic Hardware and Software Maintenance 1. Application 2. Operating System Upgrades and Patches Hardware Upgrades Design and Build A good troubleshooter - Understand the computer architecture so that it can identify what subsystem is causing the issue. - Can work with a person to identify the problem at hand. - Is patient and kind regardless of the Pibcac or ID 10T issues. - Can develop the problem solving the strategy and can under promises andover delivers How can the CPU know how to communicate with the devices that surround it? * BIOS/UEFI * CMOS * Option ROM * Device Drivers The early motherboard had multiple controllers, the gradual controllers were incorporated into the chipset the more controls were incorporated into the CPU package so that the numbers of the chips in the chipset have been reduced. The Intel's current chip that incorporates the controls and that works with the CPU to communicate with the peripherals that is called the Platform Controller Hub.

Operators in C language

Image
Operators One of the most important features of C is that it has a very rich set of built in operators including arithmetic, relational, logical, and bitwise operators. An operator can be any symbol like + - * / that specifies what operation need to be performed on the data. For ex: + indicates addition operation * indicates multiplication operation Operand VS Operator • An operand can be a constant or a variable. • An expression is a combination of operands and operators that reduces to a single value. For example: Consider the following expression: a+ b Here 'a' and 'b' are operand while 't' is an operator Operators & Expression are 1) Arithmetic Operators and Expressions 2) Assignment and Compound Assignment Operators 3) Increment and Decrement Operators 4) Relational Operators and Expressions 5) Logical Operators and Expressions 6) Bitwise Operators and Expressions Arithmetic Operators An arithmetic operator performs mathematical operators such

3D printers

3D  printers  A 3D printing or additive manufacturing is a process of making three dimensional solid objects from a digital file. The creation of a 3D printed object is achieved using additive processes. In an additive process of an object that is being created by laying down successive layers of material until the object is created. Each of these layers can be seen as a thinly sliced cross-section of the object. 3D printing is the opposite of subtractive manufacturing which is cutting out / hollowing out a piece of metal or plastic with for instance a milling machine. 3D printing enables you to produce complex shapes using less material than traditional manufacturing methods. Slicing: From printable file to 3D Printer Slicing basically means slicing up a 3D model into hundreds or thousands of layers and that is done with slicing software. When your file is sliced, it’s ready for your 3D printer. Feeding the file to your printer can be done via USB, SD or Wi-Fi. Your sliced file is now
