PowerPoint Presentation

[Audio] Good morning everyone. Welcome to this workshop on computer networks. Today we will be exploring the various types of storage devices and computer memory as well as the peripheral devices used to connect to a computer. We will also discuss the different uses for each type of device and memory. So let's get started!.

[Audio] Let's take a comprehensive look at storage and peripheral devices as well as different types of computer memories. We'll start by studying and demonstrating storage devices like pen drives memory cards hard drives RAM ROM DVD's and CD's. Then we'll move on to peripherals like printers scanners webcams and speakers. Finally we'll examine primary and secondary computer memories..

[Audio] Storage devices are an essential part of any computing system or network. They are responsible for keeping and preserving data for both short-term and long-term. Storage devices can be either internal or external providing more options for data storage and retrieval. The right storage device can provide a trustworthy and safe system for storing your data..

[Audio] Pen drives or U-S-B flash drives are small removable storage devices which allow us to store large amounts of data and are compatible with many computers and portable devices. Memory cards are compact portable chips designed to store and transfer digital data often fitted to cameras smartphones and tablets to expand the device's storage capacity. Memory cards use different types of flash memory technology to store data even when the device is not connected to a power source..

[Audio] Hard disks also known as hard drives or fixed disks are non-volatile storage devices that contain platters and magnetic disks rotating at high speeds. This means that the data stored on them will remain even when the computer is shut down. They are installed within a drive unit on the computer's motherboard and typically consist of one or more platters encased in an air-tight casing..

[Audio] The term CD ROM stands for "Compact Disk Read-Only Memory" a type of disk that can be read by a computer with an optical drive. As the title implies the data on the disk is "read-only" meaning the user can only access and view the information but not modify or delete it. Its storage capacity and feature makes it a great choice for data storage and transfer in computer science and its applications. When it was first introduced it could store up to 600 megabytes of data but now it can store up to 700 megabytes. CD-ROMs use similar technology to audio CDs but are structured differently allowing them to store different kinds of data. Nonetheless it was thought of as a good idea at the beginning but in the end it turned out to be a mistake..

[Audio] D-V-D-s are a great way to store large amounts of data. They are particularly useful for backing up computer files or for storing videos and audio. D-V-D-s are much more durable reliable and secure than other types of media such as cassettes or CDs. They can be stored in a variety of ways such as in plastic cases in binders or in special storage racks. D-V-D-s are also more affordable than other forms of media making them an attractive option for many users." D-V-D-s are becoming an increasingly popular medium for storing digital data. Their larger storage capacity durability and affordability make them an attractive choice for storing anything from computer data to videos and audio. With a variety of types and storage options available D-V-D-s are becoming a go-to choice for anyone looking to store large amounts of digital data..

[Audio] Good afternoon everyone. Today I'd like to talk about peripheral devices and their components. Peripheral devices are those auxiliary computer devices that provide input and output functions to a computer. Examples of input devices include keyboards and mice; output devices include printers scanners and webcams; and storage devices include U-S-B-s and hard drives. As you can see peripheral devices are essential components of any computer. Without them computers simply wouldn't be as effective and efficient. That's why it's important to understand the details and functionality of peripheral devices and their components. Thank you for your attention..

[Audio] Scanners are an important piece of hardware for a current computer system. They give us the capacity to rapidly and effectively convert information from physical sources for example paper documents magazines and photos into digital structures. This digital data can then be kept altered and printed without difficulty. Scanners enable us to interface the physical and digital universes making it simpler to utilize complex data..

[Audio] Printers are essential parts of computer networks allowing us to print data on paper. There are various types of printers such as dot matrix character line laser and inkjet printers. Each type has a specific purpose with some being better suited for one task than another. For instance laser printers are great for producing high-quality text documents and dot matrix printers are ideal for generating multiple copies very quickly..

[Audio] Computer speakers are an integral part of the modern computing experience. They offer clear and convenient audio no matter what you're doing playing music watching a film or joining an online meeting. There are a variety of options available from the latest advances in technology such as wireless and Bluetooth capabilities. This allows for easy connection of audio to computers and other devices even if you're not in one place. Get ready to explore the world of sound with the perfect set of computer speakers..

[Audio] A web camera is a device that records video of the area in front of it making it a type of input device. It can be installed internally on a laptop or other computer or connected externally using a U-S-B connection. It may also be referred to as a computer-connected digital video camera. Web cameras allow users to take photos or HD recordings although the quality may not be as high as other devices such as mobile phones or cameras..

[Audio] We will discuss the various types of computer memories. Starting with the Primary Memory or Internal Memory consisting of Random Access Memory (R-A-M--) Read-Only Memory (R-O-M--) and Cache Memory. R-A-M is used to read and write memory that contains the instructions and data for processing. R-O-M programmed by the manufacturer has the essential instructions for computer start up. Cache Memory accelerates the computer by keeping the often used instructions and data. Then we have the Secondary Memory or External Memory which includes Solid State Drive (S-S-D--) Compact Disc (C-D---) Floppy-disk and Magnetic Tapes. S-S-D-s are non-volatile and quick while CDs are used to store and transport data and information. Floppy Disks are a storage medium with low capacity and Magnetic Tapes are used for archiving large amounts of data for long-term storage. We have now completed our discussion on the assorted types of computer memories..

[Audio] The two types of computer memory are primary memory and secondary memory. Primary memory also known as main memory is used by a computer system for the temporary storage of data while being used. Secondary memory stores information for later use. Primary memory is more expensive but faster while secondary memory is cheaper but slower. Primary memory holds data that is currently processed and is removed when the computer is turned off while secondary memory stores data even when the computer is turned off. The two types of memory work together to ensure faster computing by processing data..

[Audio] R-A-M is a type of hardware that stores data that is currently being used. It is also referred to as primary or main memory. There are two types of RAM Static R-A-M and Dynamic R-A-M which store data differently. Static R-A-M stores a bit of data using a six-transistor memory cell while Dynamic R-A-M stores a bit of data using a pair of transistors and capacitors which constitute a D-R-A-M memory cell. This type of memory is essential for the C-P-U to quickly and easily access data in real time..

[Audio] R-O-M or Read-Only Memory is a type of permanent and non-volatile memory which contains pre-recorded data which is essential for a computer's boot-up process. R-O-M is usually found in embedded parts where few programming changes are necessary. The R-O-M chip found on the motherboard contains a program called B-I-O-S or Basic Input Output Setup that checks the status of all connected devices and allows them to interact with the system..

[Audio] When it comes to storing large amounts of data there are many secondary memory options available. These include static devices such as hard drives CDs and D-V-D-s as well as removable devices like pen drives and blue ray discs. Each of these media have different storage capacities which enables us to pick the most suitable for our needs. Moreover with the more advanced technology used in blue ray discs users can store even more data in the same amount of space making it a great choice for those requiring greater storage..

[Audio] I'm sure this information will be useful to you in the future. I hope you enjoyed the presentation and learned something new. Thank you for listening and taking the time to learn about Computer Network and for your attention..
