Answers
Answer:
1. Even devices such as smartphones, tablet computers, and wearable deviceslike fitness trackers and smartwatches can be considered as peripherals, albeit ones that can function independently. Flash-memory drive with USB on a laptop computer. Various standards for connecting peripherals to computers exist.
2. A scanner is an input device that captures documents such as photographs and text.Scanners are of many types according to their design, scanning mechanisms etc. When a document is to be scanned, firstly a documents is converted into digital signal and then scanning is performed on this electronic version of document.
3.A monitor is an electronic visual computer display that includes a screen, circuitry and the case in which that circuitry is enclosed. Older computermonitors made use of cathode ray tubes (CRT), which made them large, heavy and inefficient.
In digital imaging, a pixel, pel, or picture element is a physical point in a raster image, or the smallest addressable element in an all points addressable display device; so it is the smallest controllable element of a picture represented on the screen.
4. A hard disk drive (sometimes abbreviated as a hard drive, HD, or HDD) is a non-volatile data storage device. It is usually installed internally in a computer, attached directly to the disk controller of the computer's motherboard. It contains one or more platters, housed inside of an air-sealed casing.

3.What do you understand by a Monitor? Define pixels.
The term "pixel" is actually short for "Picture Element." These small little dots are what make up the images on computer displays, whether they are flat-screen (LCD) or tube (CRT) monitors. The screen is divided up into a matrix of thousands or even millions of pixels.

4.What is HDD? Briefly explain its configuration.
A hard disk drive (sometimes abbreviated as a hard drive, HD, or HDD) is a non-volatile data storage device. ... Data is written to the platters using a magnetic head, which moves rapidly over them as they spin. Internal hard disks reside in a drive bay, connected to the motherboard using an ATA, SCSI, or SATA cable.
