Computer Parts Presentation
This document lists and defines common computer hardware components including the monitor, CPU, keyboard, mouse, disk drive, flash drive, headphones, printer, speakers, document camera, smartboard, webcam, iPad, laptop, and encourages identifying each component and playing a matching game to learn the names.
Slide Show 2 2
The document discusses the main components that make up a computer workstation:
The power supply provides power to the computer and components when plugged into an electrical outlet. The keyboard allows users to type, search, and write documents. Computer monitors usually use LCD or CRT display technologies, with LCD becoming more common in desktops due to its slimmer design and lower energy use. The mouse is a pointing device used to control the cursor on the screen and includes buttons. Speakers connect via audio jack to play sound from the computer. A webcam and microphone allow for video chatting. A flash drive uses solid-state memory for portable data storage.
Computer presentation.
This multimedia presentation summarizes the latest configurations of modern desktop computers, laptops, tablets, and smartphones. It includes details on the specifications of a MacBook Pro, iPhone 5s, Asus laptop, and Samsung Galaxy tablet. The presentation is divided into sections covering operating systems, processors, motherboards, hard disks, RAM, and specific device configurations.

This document presents the key components of electronic data processing (EDP) systems, including hardware, software, and peopleware. It outlines the main input devices like keyboards and mice, output devices like monitors and printers, processing devices like the central processing unit, storage devices like hard disks, and communication devices like routers. It also lists some other hardware components and provides operating systems as an example of software. The presentation was prepared by Joe Capiral for his instructor Mr. Christopher Seno.
Disassembling Of the old working pc (part-1)
Disassembling Of the old working pc
In this Instruction, I will give a full documentation of how to disassemble a desktop PC, for parts. The specific computer that I will demonstrate with is an HP Media Center PC m7640n with a dead motherboard. Every computer is different, but this is a general guide.
If you don't fully grasp what I mean when I am describing something, please refer to the pictures!
Step 1.
Selection the required tools and equipment:
1. Screw Driver.
2. Multimeter.
3. Soldering iron.
4. Contract cleaner.
5. Brush.
Step 2.
To turn off the power:
If the PC being running, must shut down the pc before disassembling.
There are many ways to shut down your PC—you can turn the PC off completely.
Turn your PC off completely
To shut down:
For Windows 10 Select the Start button and then select Power > Shut down.
For Windows 8.1 / Windows RT 8.1
Move your mouse to the lower left-hand corner of the screen and right-click the Start button or press Windows logo key + X on your keyboard. Tap or click Shut down or sign out and choose Shut down.
For Windows 7 Click the Start button and then click the Shut down button. Click the Start button and then click the Shut down button.
Step 3: Unplugging
The first thing you do, is unplug every cable that's plugged in to your computer. That includes the following cables:
________________________________________
• Power
• USB
• Firewire
• Mouse
• Keyboard
• Internet
• Ethernet
• Modem
• AM\FM Antenna
• Cable TV
• etc...
So pretty much just unplug every cable from your computer.
Step 2: Outer Shell/Casing
Now that your computer is fully unplugged, move your PC to a clean work space, preferably a carpet. The carpet is better than tile, because screws and other small parts will roll around.
NOTICE:
If you are working on a carpet, about every five minutes touch something that is grounded (Sink faucet\pipe, wire coming from the ground part of a wall outlet). This is so you don't shock your motherboard or other parts.
First off, unscrew the four screws on the back of the computer. On most computer cases, there will be large knobs that you can unscrew by hand or by screw driver on the back-right side of the computer. The left side has small screws because on that side you can't access much on the inside.
Once the screws are removed, you can remove the side panels. On most computers, they just slide off. Start with the left side panel (the side that once had the knobs), slide it towards the back of the computer. Now you can remove the left panel. Just like the other one, slide it towards the back of the computer.
Please refer to the pictures if you are confused!
Step 3: Outer Shell/Casing (cont.)
In the last step I removed both side panels. In this step, I will be removing the front and top panels.

Computer 10 Other Parts of the Internal System Unit
The document provides instructions for assembling a computer system. It begins by listing the objectives of understanding the other internal parts of a computer and the assembly process. It then describes the various internal components like the RAM, ROM, storage devices, buses, video card, sound card, and cooling system. The last part provides a step-by-step guide to assembling the computer, including preparing the workspace, gathering tools and components, and connecting the motherboard, processor, memory and other parts inside the case.
Motherboard
A motherboard connects the main components inside a computer including the CPU, RAM, expansion cards, and ports. It has sockets for these parts and connects them through cables and wires. The CPU performs most processing and relies on the motherboard, memory, storage, and buses. A heat sink and fan are attached to keep the CPU from overheating as it works. The motherboard also contains the BIOS that performs startup checks and allows access to system settings.
Yadu computer internals final-2
A computer is a device that calculates and processes data. It consists of both hardware and software. The hardware are the physical parts like the keyboard, monitor, CPU etc. The software are programs like Word, Excel etc. The CPU is the brain of the computer and processes instructions. Memory temporarily stores data and instructions for processing. Different types of computers include PCs, servers, supercomputers and more.

- 1. Computer Peripherals This blog mainly consist of COMPUTER HARDWARE,NETWORKING as well as SOFTWARE Troubleshooting. Keep your laptop cool Keeping your laptop cool is critical for extending its life. Laptops can overheat for a variety of reasons, the most common of which is that they are dirty or that the fan has failed. Overheating frequently can cause internal damage to your laptop's motherboard, preventing the computer from functioning properly or at all. Use these techniques to keep your laptop cool. Steps to Follow (Computer Peripherals) Place your laptop on a towel on a solid surface when it is on. Alternatively, clean out any dust inside. Start by carefully removing the screws from the bottom of the laptop and setting them aside. Do not lose or drop them. Remove the face cover from the unit's CPU . Set aside. Using your pressurized computer air duster (or hair dryer), clean and blow out all of the dust inside the laptop. Make sure you get in between the blades of the fan and other hard-to-reach places. Screw the bottom of the laptop back on. A third option is turning your computer on and setting a desktop fan next to the side of the computer with the vents and the internal computer fan. This helps keep the entire system cool. Components of the Computer System MAJOR HARDWARE COMPONENTS OF A COMPUTER SYSTEM SYSTEM UNIT It is also called the computer case, computer chassis, or computer tower. Cases are typically made of steel or aluminum, but plastic can also be used. While most computer cases are rather dull, black, metal boxes, some manufacturers try to give the unit some flair with color and special design elements. MOTHER BOARD / SYSTEM BOARD A motherboard is one of the most essential parts of a computer system. It holds together many of the crucial components of a computer, including the central processing unit (CPU), memory and connectors for input and output devices
