INDEX. Study and Demonstration of Storage Devices: Pen drive, Memory Card, Hard Disk, RAM, ROM, DVD,CD. Study and Demonstration of Peripheral Devices: Printer, Scanner, Web Cam, Speakers. Study Practical of Types of Computer Memories: Primary Memory, Secondary Memory ..

Introduction. What is Storage Device A storage device is also known as the “Storage Medium, Storage Media or Digital Storage“. Definition: Storage device is a computer hardware component that helps to store, porting or retrieving data files and objects. Storage devices are capable to store information in both natures like as temporarily and permanently. These devices may be used for internal or external to a computer, server or computing device..

Hard disk:. [image]. A hard disk is also known as a hard drive or fixed disk. It is said to be rigid magnetic disc that stores data. It is located within a drive unit. Hard disk is a non-volatile storage device that contains platters and magnetic disks rotating at high speeds. Non-volatile means the data retains when the computer shuts down. It is installed internally in our computer systems. Hard disk is located within a drive unit on the computer's motherboard and comprises one or more platters packed in an air-sealed casing..

[image] CD. The term CD ROM implies "Compact Disk Read-Only Memory." A CD-ROM may be a CD which is perused by a computer framework with an optical drive. "ROM", as its title implies the information on the disk is within the frame of "read-only," which implies the client can examine the information as it were; they cannot delete or adjust it. Due to this include and its capacity capacity, CD-ROMs are an astonishing media plan to information capacity and change within the world of computer science and its application. At the time of propelling CD-ROMs, it might store around 600 MB of data/data, in any case presently they can store up to 700 MB. Compact circle ROMs share a comparable innovation as sound/audio CDs, be that as it may, they are shaped in an unexpected way, allowing them to store distinctive sorts of information..

DVD:. The term DVD means "Digital Versatile Disk" A DVD is a kind of optical media used to keep digital data. It is a similar size as a CD, yet has a large storage capacity. A few DVDs are organized explicitly for video playback, while others may contain various kinds of data, for example, software projects and computer data backup. The first "DVD-Video" design was established in 1995 by a consortium of electronics organizations like Sony, Philips, Panasonic, Toshiba, etc..

Study and Demonstration of Peripheral Devices: Printer, Scanner, Web Cam, Speakers. Course Module Guidelines.

Scanner : A scanner is an input gadget that capacities so also to a printer. It’s utilized when there's data on paper that should be exchanged to the computer's difficult circle for consequent control. The scanner collects pictures from the source and changes over them to a computerized arrange which will be spared on a circle. Some time recently they are printed, these pictures can be altered..

Printer:. Printers are yield gadgets that permit you to print data on paper. There are certain sorts of printers which are depicted underneath. Affect Printers Character Printers Line Printers Non-Impact Printers Laser Printers Inkjet Printers.

Speakers. Computer speakers are the foremost well known yield gadgets utilized with a computer to tune in to sound. These speakers get sound as input either in analogy or advanced frame and create sound as an yield. With the headway of innovation, speakers are presently accessible with remote and Bluetooth offices as well. Speakers are gadgets that create sound after getting a command from a computer. These days, speakers come with remote innovation moreover like Bluetooth speakers..

Web Camera:. Since a web camera records a video picture of the scene before it, a webcam is an input gadget. It is either built interior the computer (for case,a portable workstation) or joined through a USB association. A webcam may be a computer-associated modest advanced video camera. It's too known as a web camera since it can take pictures and record video. These cameras come with program that must be introduced on the computer in arrange to broadcast video in real-time over the Web. It can shoot pictures and HD recordings, be that as it may, the video quality isn't as great as other cameras (In Mobiles or other gadgets or typical cameras)..

Study Practical of Types of Computer Memories: Primary Memory, Secondary Memory ..

Memory. Memory is one of the basic and critical parts of the computer. We cannot say that there's as it were one sort of memory in our framework that's working. There are layers of memory accessible within the computer that can make together and increment the execution of the computer. So what are distinctive sorts of recollections? What are the uses of those recollections and how they work collectively? We are going examine this in our article. Computer memory is partitioned into two sorts: Primary memory Secondary memory.

Random Access Memory Programs and data needed by the CPU in real time are stored in Random Access Memory (RAM). Random access memory allows for unlimited reading, writing, and erasing of data. RAM is a type of hardware that stores data that is being used right now. Its memory is erratic. It is also referred to as primary or main memory. The user's memory is this. When the application or those files are opened, the data files and software (program) are kept on the hard drive. RAM is used to expand them. It is a user's area wherein the user saves temporary data into secondary storage devices or lets it be automatically stored. Types of RAM Static RAM: Static RAM or SRAM stores a bit of data using the state of a six-transistor memory cell. Dynamic RAM: Dynamic RAM or DRAM stores a bit of data using a pair of transistors and capacitors which constitute a DRAM memory cell..

Read-Only Memory: Pre Recorded data is stored in a type of memory called read-only memory (ROM). Non-volatile data is kept in RAM long after the machine has been powered down. It is typically utilized in embedded parts, where there aren't many programming adjustments needed. Another name for it is secondary memory. This permanent CNO4 erasable memory is activated when the computer is powered on. A RAM chip installed on the motherboard at the time of manufacture is called ROM. A program known as BIOS (Basic Input Output Setup) is stored there. Every device connected to the computer has its status checked by this software..

Secondary memories: External memory serves as the auxiliary memory. Secondary memory operates at a slower speed than primary memory. However, the secondary memory has a larger storage capacity than the primary memory. We can upgrade the secondary RAM to meet our needs. Possible secondary memory types include: Fixed device: Hard disk CD / DVD drive Removable device: Pen drive blue ray disc It is an optical storage media that is used to store high-definition video and multimedia files. It uses shorter wavelength lasers as compared to CDs and DVDs that means it is again using optical Ray’s to store data because it uses shorter wavelength optical Ray’s that means more and more data can be written into the same amount of space so this enables writing arm to focus more tightly on the disc and hands back in more data more data as compared to CDs and DVDs it can usually store up to 128 GB of data so this was all about different types of secondary memory devices that we can use to store our data instructions..
