Computer Monitors

  Computer Monitors There are several types of computer monitors available, each with its own advantages and disadvantages. The main types include CRT, LCD, LED, OLED, and specialized monitors like curved, touch, and gaming monitors.  Here's a breakdown of the different monitor types: 1. CRT (Cathode Ray Tube) Monitors: ·          These are the older, bulkier monitors that use a cathode ray tube to project images.  ·          They are less common now due to their size and energy consumption.          2. LCD (Liquid Crystal Display) Monitors: ·          LCD monitors are the most widely used type, known for their relatively thin profile and lower power consumption compared to CRTs.  ·          They use liquid crystals to block or transmit light, creating...

Plotter

  Plotter A plotter is a specialized type of printer that produces vector graphics drawings by moving a pen, knife, or other drawing tool across the surface of paper or other materials. Unlike standard printers that create images from dots, plotters draw continuous lines, making them suitable for large-format output like architectural plans, engineering schematics, and detailed maps.  Key Characteristics of Plotters: ·          Vector-based Output: Plotters generate images by drawing lines based on vector graphics data, which allows for precise and scalable drawings.  ·          Large Format Printing: They are commonly used for large-format printing, such as architectural and engineering drawings, and can handle various media sizes.  ·          Drawing Tools: Plotters utilize different tools like pens, pencils, markers, or ...

Printers Impact Printers: Non-Impact Printers:

    Printers Printers are categorized into two main types: impact and non-impact. Impact printers create an image by physically striking an inked ribbon against the paper, while non-impact printers use various methods like ink sprays, lasers, or heat to transfer the image without direct contact.  Impact Printers: ·          Mechanism: Impact printers use a print head that strikes an inked ribbon, pressing the ribbon against the paper to create the desired characters or images.  ·          Examples:  Dot matrix printers are a common type of impact printer.  ·          Pros:  Can create carbon copies, relatively inexpensive.  ·          Cons:  Noisier, lower print quality, limited graphics capabilities.  Non-Impact Printers: ·     ...

Storage hardware

  Storage hardware refers to  the physical components within a computer system or external device that are used to store data , such as hard drives, solid-state drives, and USB flash drives.  These devices allow users to save and retrieve digital information like documents, images, videos, and software application Hard Disk Drives (HDDs): ·          HDDs are a type of magnetic storage device that store data on rotating platters. ·          They are a common and cost-effective solution for storing large amounts of data.  Solid State Drives (SSDs): ·          SSDs utilize flash memory to store data, offering faster read and write speeds compared to HDDs.  ·          They are also more durable and consume less power than HDDs.      USB Flash Drives: ·     ...
