[Audio] HI Computer a programmable electronic device designed to accept data, perform prescribed mathematical and logical operations at high speed, and display the results of these operations. Mainframes, desktop and laptop computers, tablets, and smartphones are some of the different types of computers. BASIC OPERATIONS OF THE COMPUTER.

[Audio] COMPUTER HARDWARE WHAT IS IT? COME ON LETS ANSWER THIS QUESTION?..

[Audio] COMPUTER HARDWARE Hardware refers to the physical, tangible computer equipment and devices, which provide support for major functions such as input, processing (internal storage, computation and control), output, secondary storage (for data and programs), and communication..

[Audio] There are 6 components of computer hardware these are Input devices Output devices Central processing unit Memory Storage devices Communications devices.

[Audio] Main Personal Computer Hardware Parts Motherboard CPU RAM Memory Expansion card Optical disk Drive Hard Disk Power Supply Keyboard Monitor Mouse.

[Audio] Computers are composed of the many different hardware types Internal External Storage Communication.

[Audio] Internal Hardware are hardware found inside the system unit. Motherboard is the central circuit board found inside in the system unit. All other hardware is plugged into the motherboard. Central Processing unit ( CPU)- performs most of the calculations that enable the computer to function. It is referred to as the " brain" of the computer. Since it does most of the " thinking", it is usually cooled by a heat sink and fan. RAM or Random Access Memory- stores all running processes including the applications the operating systems. It is a computer primary memory. ROM or Random Access Memory is a type of primary storage medium that permanently store data on Pcs and other electronic device..

[Audio] Power supply- sends the power through cables to the motherboard and other components. Sound card- enables the computer to output sound to audio devices and accept input from a microphone. Graphics card is plugged into the mother board and makes the computer to display images on the monitor. Fan – act as a heat sink it keeps the CPU cool and stops from overheating. Expansion Slots- is the slots on a motherboard it can hold an expansion card like video card network card or sound card to expand the computer's functionality. Drives Hard disk drive, Floppy disk, Optical disk drive are connected to the mother board. Note: the hardware, will not work without BIOS or Basic Input/ Output System which includes boot instructions and power management. Its tasks are handles by operating system drives..

[Audio] EXTERNAL DRIVE Are hardware found outside the system unit and they are connected to the system unit. They are 3 categories Input devices Output devices Storage devices External hardware's components are so called peripherals They perform three main functions. Receive data from user. Convert data into binary form (the language of 0and 1 also called machine language. Machine Language is the only language of the computer that can understand directly. Provide converted data to computer memory for processing..

[Audio] Input devices Keyboards- it is the most familiar input device. it allows the computer to input letters, numbers and other symbols into a computer. Typing keys Alphabet keys ( A_Z, a-z) and number keys ( 0- 9) 12 function keys, used for specific purposes Cursor and screen control keys, Ex. Arrow keys, page-up , Page Down control ( ctrl) Alternate( ALT), escape( esc), Home , End , insert , delete. Operator and special characters' keys Special Purpose keys enter, Backspace, Numlock, Caps-lock, Shift, Space Bar, tab, Scroll Lock, Sleep & print screen Number keypad. Types of keyboards Standard Keyboards Ergonomic keyboard Wireless keyboard Compact keyboard Internet keyboard Gaming Keyboard Virtual Keyboard.

[Audio] Monitors- are the most popular output devices used today for producing soft copy output. They display the generated output on a television like screen. Basic types of monitors used today are: Cathode Ray Tube ( CRT) Liquid Crystal Display (LCD) Plasma Touch Screen OLED( Organic Light Emitting Display Cathode Ray Tube (CRT)- this is the most common computer monitors until flat panel screens became affordable. It is similar to older TVs, CRT monitors still typically have much better contrast ratios and viewing angels than other computer monitor alternatives. Liquid Crystal Display ( LCD)- this saves a lot space and can even be mounted on walls. It provides a wide angle and come in sizes typically ranging from 17-inches to 60 inches. Plasma- this is commonly used with computers due to their high operating temperatures, high power consumption, and fixed resolution. Touch Screen-this provides a new way of interacting with your computer with a touch sensitive screen. This allows a user to interact directly with the application on screen without need for a mouse or keyboard. OLED(Organic Light Emitting Display) This is much thinner and lighter than LCD or Plasma screens. OLED monitor can also be placed on transparent surfaces, such as glass, allowing the user to see through them when not active..

[Audio] MOUSE Mouse- is another important tool for communicating with computers. Commonly known as a pointing device, it lets you point to objects on the screen, click on them, and move them. There are two main mouse types: Optical and Mechanical The optical mouse uses an electronic eye to detect movement and is easier to clean The mechanical mouse uses a rolling ball to detect movement and requires regular cleaning to work properly..

[Audio] OUTPUT DEVICES Output devices - is a piece of hardware that is used receiving information from a computer. hear, see, or otherwise recognize the results of information-processing requests. They can broadly have classified into the following categories: Monitors Printers Plotters Screen image projector Voice response systems Output devices generate computer output that can be broadly classified into following two types: Soft copy output- A soft copy output is not produced on a paper or some material that can be touched and carried for being shown to others. Hard copy output – is produced on a paper or some material that can be touched and carried for being shown to others..

[Audio] PRINTERS Printer Are the most popular output devices used today for producing hard copy Impact Printers It works by direct contact of an ink ribbon with paper output. Different types of printers are described below: Dot-Matrix Printers Are character printers that print one character that print one character at a time. A Dot matrix printer has a print head that moves horizontally (left to right and right to left) across the paper. Normally slow with printing speeds ranging 30 to 600 characters per second. Daisy Wheel A daisy wheel printer is a specific type of mechanical impact printer popular in the 1970s that used individual letter, number and symbol keys to imprint text on paper. Non- Impact printer Inkjet Printers Are characters' printers that form characters and all kinds of images by spraying small drops of ink on paper. Inkjet printers produce higher quality output than dot- matrix printers do because they form characters by very tiny ink dots. Thermal Printers A thermal printer is a type of printer that uses a heated thermal print head pressed against a medium to produce black text or images Laser Printers Are page printers that print one page at a time. Laser printers are non-impact printers Produce very high quality output because they form characters by very tiny ink particles. Drum Printers Are line printers that print an entire line at a time. They can use to produce, multiple copies by using carbon paper or its equivalent Chain/ Band Printers Are line printers that print one line at a time. It consists of a metallic chain/ band on which all characters of the character set supported by the printer are embossed. Chain/ band printers are impact printers because they print by hammering on a paper and inked.

[Audio] Headset This is a combination of speakers and microphone. It is mostly used by gamers, video conference, online meeting etc. Projector this device a computer created image into another surface, usually whiteboard or wall. It is most widely used for presentations or for viewing videos. Speakers Are to facilitate the output sound of digital sound.

[Audio] Difference of Input Devices and Output Devices as you can see there some devices that can be input device and also it can be a output device. Note: It is important that some devices work as both input and output devices. They can accept input as well as produce output..

[Audio] Storage Devices There is hardware that keeps data inside the computer for later use and remains persistent even when the computer has no power. Hard Disk for medium-term storage data Solid state drives a device similar to hard disk but containing no moving parts and stores data in a digital format. Raid Array Controller a device to manage a several internal or external hard disks and optionally some peripherals in order to achieve performance or reliability improvement in what is called a RAID array.

[Audio] Removable Media is any type of storage device that can be removed from a computer while the system is running. Example of removable media includes CDs, DVD, s and Blu-ray disks, as well as diskettes and USB drives. Removable media makes it easy for a user to move data from one computer to another. Types of Removable Storage Devices CD ( compact disc) CD- ROM Drive CD Writer DVD ( Digital Versatile Disc) DVD- ROM Drive DVD Writer DVD-RAM Drive Blu-ray Disc- BD- ROM Drive BD writer CompactFlash ( CF) card Smart Media ( SM) card Memory Stick Media card Floppy disk Flash memory device Iomega Zip Drive USB Flash Drive Tape drive xD-Picture ( xD) card Secure Digital ( SD) card and Multimedia Card ( MMC) HD DVD.

[Audio] Communication Device Modems A modems is what allows a computer to communicate with the outside world. It is most commonly used to connect computers to the internet , but can also be used to communicate directly with another computer. The word " modem" is a contraction of the words modulator-demodulator. It is a communication device which allows your computer to communicate with other computers over a communication link. Modem Function Modulation / Demodulation Error connection Compression / Decompression Modem types Standard Analog ( phone/ voice/ fax) ISDN modems Digital cables modems Xdsl Modem Satellite.

[Audio] Cable or DSL modem – The installer will in all like hood provide the user with the necessary modem. This usually an external modem that hooks up to either the network card or the USB port. The user must have cable or DSL service in order for the cable or DDSL modem to work on the system. Types of modems that are currently used: Dial –up Modems- these are modems which connect computers via a phone line; it also connects Broadband modes which have a high-speed connections to the internet. Router- A router is a significant network communication device. Its task is to send network traffic to its correct destination. It works by reading the destination network address within each pocket and transmit it along its way. There can be more than one router on a large network. Hub- a hub is the most basic networking device that links multiple computers or other network devices together. Unlike the switch and routers, a hub has no intellect on where to send information and broadcast all data across connection..

[Audio] Using the process of elimination If you're having an issue with your computer, you may be able to find out what's wrong using the process of elimination. This means you'll make a list of things that could be causing the problem and then test them out one by one to eliminate them. Once you've identified the source of your computer issue, it will be easier to find a solution..

[Audio] Have you experience this the printer won't print..

[Audio] Let me help you. Business <strong>Woman</strong> by Shipahn on DeviantArt.

[Audio] First, you check the printer to see that it's turned on and plugged in to the surge protector You check the printer's USB cord and find that it's not plugged in. You must have unplugged it accidentally when you plugged something else into the computer earlier. Once you plug in the USB cord, the printer starts working again. It looks like this printer issue is solved! Now you want to make sure the printer and computer are communicating correctly. If you recently downloaded an update to your operating system, it might interfere with the printer. But you know there haven't been any recent updates and the printer was working yesterday, so you'll have to look elsewhere. Next, you check to make sure the printer's ink cartridge still has ink and that there is paper loaded in the paper tray. Things look good in both cases, so you know the issue has nothing to do with ink or paper.

[Audio] Power button won't start Let me help you.

[Audio] Problem: Power button will not start computer Solution 1: If your computer does not start, begin by checking the power cord to confirm that it is plugged securely into the back of the computer case and the power outlet. Solution 2: If it is plugged into an outlet, make sure it is a working outlet. To check your outlet, you can plug in another electrical device, such as a lamp. Solution 3: If the computer is plugged in to a surge protector, verify that it is turned on. You may have to reset the surge protector by turning it off and then back on. You can also plug a lamp or other device into the surge protector to verify that it's working correctly. Solution 4: If you are using a laptop, the battery may not be charged. Plug the AC adapter into the wall, then try to turn on the laptop. If it still doesn't start up, you may need to wait a few minutes and try again..

[Audio] The mouse or keyboard has stopped working The mouse and keyboard has stopped working I need to my exam!!! The mouse and keyboard has stopped working I Will rest. The mouse and keyboard has stopped working. I'm in hurry ah!!! Let me help you.

[Audio] The mouse or keyboard has stopped working Solution 1: If you're using a wired mouse or keyboard, make sure it's correctly plugged into the computer. Solution 2: If you're using a wireless mouse or keyboard, make sure it's turned on and that its batteries are charged..

[Audio] Problem: The sound isn't working Let me help you.

[Audio] Problem: The sound isn't working Solution 1: Check the volume level. Click the audio button in the top-right or bottom-right corner of the screen to make sure the sound is turned on and that the volume is up. Solution 2: Check the audio player controls. Many audio and video players will have their own separate audio controls. Make sure the sound is turned on and that the volume is turned up in the player. Solution 3: Check the cables. Make sure external speakers are plugged in, turned on, and connected to the correct audio port or a USB port. If your computer has color-coded ports, the audio output port will usually be green. Solution 4: Connect headphones to the computer to find out if you can hear sound through the headphones.

[Audio] The screen is blank!!!!. OMETHIN WENT WRONG.

[Audio] Problem: The screen is blank Solution 1: The computer may be in Sleep mode. Click the mouse or press any key on the keyboard to wake it. Solution 2: Make sure the monitor is plugged in and turned on. Solution 3: Make sure the computer is plugged in and turned on. Solution 4: If you're using a desktop, make sure the monitor cable is properly connected to the computer tower and the monitor..

[Audio] Solving more difficult problems If you still haven't found a solution to your problem, you may need to ask someone else for help As an easy starting point, we'd recommend searching the Web. It's possible that other users have had similar problems, and solutions to these problems are often posted online. Also, if you have a friend or family member who knows a lot about computers, they may be able to help you..

[Audio] Keep in mind that most computer problems have simple solutions, although it may take some time to find them. For difficult problems, a more drastic solution may be required, like reformatting your hard drive or reinstalling your operating system. If you think you might need a solution like this, we recommend consulting a professional first. If you're not a computer expert, it's possible that attempting these solutions could make the situation worse..

[Audio] A peripherals is a piece computer hardware that is added to a computer in order to expand its abilities. As opposed to hardware that is either demanded or always required in principle, peripherals are those devices that are optional in nature.

[Audio] Other Peripherals Pointing Input Devices- Is an input device which is used to control the movement of the pointer to select items on a display screen. TOUCH PAD TRACK BALL JOYSTICK POINTING STICK GRAPHIC TABLET LIGHT PEN TOUCH SCREEN.

[Audio] Plotter Plotter- are ideal output device for architectures, engineers, city planners, and others who need to routinely generate high-precision, hard copy, graphic output of widely varying sizes. Two commonly used types of plotters are drum plotter and flatbed plotter. Drum Plotter The paper on which the design is to be made is placed over a drum that can rotate in both clockwise and anti-clockwise directions to produce vertical motion. The plotter can also annotate the designs and graphs so drawn by using the pen to draw characters of various sizes. Flatbed Plotter A flatbed plotter plots a design or graph on a sheet of paper spread and fixed over a rectangular flatbed table. The plotter can also annotate the designs and graphs so drawn by using the pen to draw characters of various sizes..

[Audio] SPECIAL PURPOSE OUTPUT EQUIPMENTS Document Printers (Multi-Functional Devices) An MFP (Multi- Functional Product/ Printer/ Peripheral), multifunctional, all-in-one ( AIO), or Multifunction device ( MFD) is an office machine which incorporates the functionality of multiple devices in one or to provide centralized document management/ distribution / production in a large office setting. A typical MFP may act as a combination of some or all of the following devices: Printer Scanner Photocopier Fax Email Computer Output Microfilm ( COM) is a process for copying data from electronic computer media onto microfiche or 16mm roll microfilm. COM provides an inexpensive way to preserve records from variety of electronic sources, including records that might need to be stored indefinitely but referenced only occasionally..
