![]() ![]() The sound card has a dual purpose of converting the input audio data into analog audio that can be played by the speakers, can convert the analog audio from microphones into digital data. Microphones are the input device that receives the audio signals, and speakers or headphones are the output devices to send audio data. The sound cards operate with the help of a software application and a device driver. The sound card, also known as an audio adapter is the expansion card or integrated circuit to receive and produce sound. GPS is nowadays used in smartphones, vehicles, and many other tracking devices. The GPS and satellite interact using microwave signals to give information regarding location, vehicle speed, etc. It comprises 24 satellites, expanded in space about 12000 miles above the earth’s surface. The GPS is composed of a sender and a receiver computer. ![]() Projectors are used in classrooms, offices, auditoriums, and also at places of worship, as it enables a group of people to watch videos, presentations, or pictures generated from a single computer.Ī global Positioning System or GPS is a network of satellites to know the exact location of an object on earth. The projectors can produce still images or moving images. The projectors used nowadays are known as video projectors. The older versions of the projectors used to create the image by shinning the light through a small transparent lens while the newer version projectors can project the image directly by using a laser. ProjectorĪ projector is an output device that can take images produced by a computer and project them onto a screen or surface. Most computer speakers have internal amplifiers which can increase the volume or the amplitude of the sound based on users’ requirements.Įxternal speakers are connected to a computer only if a user requires louder sounds, more bass, or surround sound. The speakers receive audio as input from the computer or a sound card then this input may be either in analog or digital form. Light is passed through liquid crystals to form pixels.Ĭomputer speakers are the most common output devices used with a computer. This technology uses liquid crystals or plasma to produce output. These screens are much lighter and thinner, which can be carried from one place to another. These monitors use a thin panel design instead of CRT technology. CRT monitor screens are large and consume more power. This technology uses phosphorescent dots to generate pixels that form displayed images. They are as follows:-Ĭathode Ray Tube monitors use CRT technology similar to television. The user can view the processed data on the screen. It includes a screen, circuitry, and the box, in which the circuit is enclosed. ![]() More the pixels, the better is the picture clarity and sharpness. It displays information in a pictorial form or commonly referred to as pixels. The monitor is the most common output device. ![]()
