Hard Disk  The 1950s saw the development of hard drives. They first appeared as huge discs with a 20-inch circumference that could only store a few megabytes. Initially known as "fixed discs" or "Winchesters" (a code name used for a popular IBM product). To distinguish them from "floppy discs," they later adopted the name "hard discs." Instead of the flexible plastic film seen in tapes and floppies, the magnetic media is stored on a hard platter in hard discs. Definition of Hard disk A fixed disc or hard drive is another name for a hard disc. It is said to be a data-storing rigid magnetic disc. It can be found inside a drive unit. A hard disc is a non-volatile storage device that has magnetic discs and platters that spin quickly. Non-volatile data is data that survives the shutdown of the computer. Internally, our computer systems have it installed. The hard disc, which is made up of one or more platters packed in an airtight shell, is housed ins

Why Android phones are better off without a Dynamic Island of their own The pill-shaped cut-out that Apple has incorporated in its new iPhone 14 Pro series is more recognizable than the 48-megapixel main camera or the A16 chipset. The Dynamic Island feature, which has been making the rounds in the tech community for weeks, appears to have the potential to 'inspire' Android phone manufacturers to implement their own notch-based indicator + multitasking feature. But is that actually required? Both Xiaomi and Realme, two well-known smartphone manufacturers that primarily target the entry-level and mid-range markets, may be thinking of integrating a variation of Apple's Dynamic Island on their own devices. A Realme blog post urges readers to "Can you picture what if Realme UI incorporated a software technique to turn the camera cutout into a multifunctional feature?" implying the feature is possibly in the works. In the meantime, Xiaomi President Lu Weibing reportedly

Ltspice transformer LTspice is an amazing SPICE reproduction device with an incorporated schematic catch. In contrast to numerous other free test systems, LTSpice is a broadly useful apparatus and not constrained. LTspice incorporates models for a large portion of Linear Technology's switch-mode DC/DC converters just as a library of gadgets for general simple circuit reenactment including operation amps, comparators, direct controllers, and discrete. In the event that you wish to think about the conduct of transformers and inductors, and investigate their secrets, maybe, at that point, LTspice is the perfect learning apparatus for this reason. LTspice will loyally demonstrate both perfect and genuine attractive gadgets, however, and  I would alert you, when initially exploring different avenues regarding something you don't completely comprehend, to make sure to incorporate sensibly practical parasitic protections (both arrangement and parallel) straightforwardly into every ind

Wilson's theory of Lightning Wilson's theory of Lightning assumes that many ions are present in the atmosphere which get themselves attached to tiny dust and water particles. It further assumes the presence of an electric field in the earth's atmosphere during fair weather directed towards the Earth. Wilson's theory of Lightning assumes that many ions are present in the atmosphere which get themselves attached to tiny dust and water particles. It further assumes the presence of an electric field in the earth's atmosphere during fair weather directed towards the earth. The field intensity is roughly 1 V/cm at the earth's surface and progressively decreases with height so that at 10,000 m it is only about 0.02 V/cm. Because of the atmospheric electric field, raindrops become polarized, the upper side gets a negative charge and the lower side a positive charge Later, the lower part of the drops attracts negative ions from the atmosphere, acquiring an overall negati

Magnetic Circuit A magnetic circuit shut way to which a magnetic field, spoke to as lines of magnetic motion, is kept. Rather than an electric circuit through which electric charge streams, nothing really streams in a magnetic circuit. In a ring-molded electromagnet with a little air hole, the magnetic field or motion is altogether bound to the metal center and the air hole, which together shape the magnetic circuit. In an electric engine, the magnetic field is to a great extent restricted to the magnetic post pieces, the rotor, the air holes between the rotor and the shaft pieces, and the metal casing.  Each magnetic field line makes an entire unbroken circle. Every one of the lines together constitutes the aggregate transition. On the off chance that the transition is separated, with the e goal that piece of it is limited to a segment of the gadget and part to another, the magnetic circuit is called parallel. On the off chance that all the motion is limited to a solitary shut circle,

Network Layer Basic Requirement of Network Layer The network layer is used to route data between different nodes on the network. It uses addresses to be able to tell which pc to send data to. This layer can also break apart larger messages into smaller chunks to be reassembled on the opposite end. Network Layer Services Guaranteed delivery Guaranteed delivery with bounded delay In-order packet delivery Guaranteed minimal bandwidth Guaranteed maximum jitter Security services 1. Guaranteed Delivery This service guarantees that the packet will eventually arrive at its destination. 2. Guaranteed Delivery with Bounded Delay This service not only guarantees delivery of the packet but delivery inside a mere host-to-host delay sure (for example, inside a hundred msec). Furthermore, the following services could be provided to a How of products between a given source and destination. 3. ln-order Packet Delivery This service guarantees that packets arrive at the destination in
