What is SSD

October 11, 2019 0





Solid State Drive (SSD)
SSD is also called Solid State Drive, SSD is a storage device. It is similar to a hard disk, but its storage capacity is much higher than a hard disk. It does not have a motor or a spinning disk like a hard disk. It uses the integrated circuit as a memory to store data. SSD is made of semiconductor just like RAM but it is a permanent storage. In which you can store data permanently. Just as the pen drive and memory card store the data, in the same way SSD also stores the data, in a way it can be said that SSD is a short form of pen drive. Is
An SSD does not have a mechanical arm, so an embedded processor (or brain), also called Controller, is used to read and write data, with the help of which a lot of work such as reading and writing of data is done.  The controller is used to find the speed of SSD. Whatever decision it takes to store, retrieve, cache and clean up the data, all these things determine the overall speed of the drive. A good controller is the real identity of a good SSD, SSD is plastic or else it is encased in a metal case, it looks like a battery.
The form factor of SSD is similar to that of a regular hard drive, its standard size is 1.8 ", 2.5", and 3.5 "size which easily fit into the housing and connectors.
Features of Solid State Drive (SSD)
1>Speed: The biggest feature of SSD is that it can read data at a much faster speed than HDD. Due to the high speed, its access time is also very short.

2>Shock resistant: It is resistant to physical shock. It does not deteriorate even if it gets jerked or falls down fast.

3>Low Power Consumption: It reduces power consumption very much compared to HDD. And it gives better performance in less power.

4>Long life: There is no moving part or mechanical part in it. This is why it has a long life.

Solid State Drive (SSD) functions
High price rate and low storage: The biggest drawback is that it is very expensive. As much as 1TB HDD can be purchased for that price, only 256 GB SSD will be available at that price. This is a new technology that is why it is not available in high storage right now.
Types of SSD:
There are many types of SSDs which have been divided according to their connectivity and speed, which is something like this.

1)      SATA SSD:
This type of SSD is similar in appearance to a laptop Hard Drive that supports simple SATA connectors in much the same way as a Hard Disk. This is the simplest form factor of SSD that you can identify by looking at it. Firstly similar SSDs came in the market and still runs. Such SSDs can be used in any PC running nowadays.

2) mSATA SSD:
 mSATA micro SATA SSD is different from normal SATA SSD both in connectivity and form factor. It is very small in size and quite different in appearance from normal SSD, it looks like a normal RAM stick. And speaking of its connectivity, it cannot be used in every PC. To use it, it is very important to have your PC mSATA port. Such SSDs are used in laptops.
3) M.2 SSD:
Such SSDs are similar in appearance to mSATA but this is its updated version which is faster than mSATA but despite being small, it supports both types of connectivity it You can also connect to a normal SATA cable and to mSATA, mSATA is just like a PCI-E express port, but it is a little smaller and specially used to connect such SSDs.
4) SSHD:
SSHD cannot be called a complete SSD because it is made up of both Solid State Drive and Hard Disk. It has some memory of SSD and some Hard Disk, it is the thing between both Hard Disk and SSD. Used in today's laptops.
How does SSD work?

As you know, there is a magnetic disk in the Hard Disk, with the help of rotation, the data transfer and access to the Hard Disk is known. But in SSD this does not happen, all the work is done by semiconductor, it takes many chips, just like RAM and because the semiconductor communicates better than the magnet, so it is so fast.

Difference between CD and DVD

Difference between CD and DVD
CDs and DVDs are versions of an optical disc that differ mainly in size and manufacturing method. Generally, a DVD can store more data than a CD, one of the reasons is that the CD has a polycarbonate substrate on only one side while the DVD has both sides present. CDs and DVDs operate on optical technology where data is exclusively retrieved using light. A laser beam is focused into a CD or DVD to read and write data stored in the disk as bits. In this post you will learn -
Definition of CD
CD (Compact Disc) was the first step towards the idea of ​​digital encoding of data. It uses a method of encoding in which a 14-bit code takes one byte and this encoding technique also helps in detecting the error. It was a suitable replacement for magnetic disks because it brought out a low-cost solution for storing significant amounts of data.

The first layer of CDS is constructed by polycarbonate plastic which stores the data in an indent pit. This layer also provides a clear glass base. A flat or non-irrigated area is known as a land. Thin aluminum material covers program discs. In the back section, the disk is stamped with a label. Pivots are arranged in a spiral track from the middle to the outside of the disk, although storing index information at the beginning of the disk reduces the risk of damage. The pits are arranged in a spiral track, out of the middle of the disk, although minimizing the risk of damage by storing index information at the beginning of the disc and the length and width of the pits are 0.8 - 3 and 0.5 μm, respectively.

Definition of DVD
The advent of DVD (Digital Versatile Disk) has provided an option for videotapes used in VCRs (video cassette recorders) and CD-ROMs, as DVDs can store 7 times larger amounts of data than CDs. It provides videos with excellent picture quality and random access. The way the material used to make CDs is also used to make material DVDs but both process and layers are different, it is used on both sides like two CDs together. Are sticking It applies various techniques for error correction, RS-PC and recording code EFM Plus. What causes DVDs to exceed CDs - dense packing of bits, use of short wavelength lasers and generation of two-sided discs (data can be drawn from both sides). A short wavelength laser is used to convert a short distance of about 0.74 μm between the spiral track and a minimum distance of 0.4 μm between the pits. Like CDs, DVDs also have variants such as DVD-R, DVD-RW. Significant differences between CD and DVD
A compact disk can store data up to 700 MB while a digital versatile disk can store a maximum of 17 GB of data.
As DVDs can acquire a larger size, it is more prevalent than a CD.
The metal layer used for recording is placed under the label on the CD. In contrast, in DVD it is located at the center of the metal layer disc.
A CD can have only one layer of pits and land, whereas in a DVD it is of two types.
A CD has a distance of 1.6 micrometers between the spiral track and 0.834 micrometers between the pits on the disk. On the other hand, the DVD has a spiral loop of 0.74 micrometers and the distance between the pits is 0.4 micrometers.
CIRC and EFMP codes are used to correct the error in the CD. Against this, special techniques are used for error correction in DVDs, including RS-PC and EFM Plus.
Difference between CD and DVD
There is no main difference between CDs and DVDs, just the difference between the two is found based on their capacity.
Difference between CD and DVD:

The CD uses only one layer. DVD 2 uses the same layer. Due to which the capacity of DVD is high.
DVDs have 6 times more memory capacity than CDs.
DVDs are used for movies and software. CDs are mostly used for music albums and commercial data.
The DVD Higher Density uses a laser-sorted web for recording and reading. CD is only single side, it uses data storage using only one layer.
Both CD and DVD can be played in a DVD player. There only CDs are played in CD player.
The conclusion
CDs and DVDs are a means of optical recording where CDs were produced as audio storage formats, while DVDs are used as universal storage formats. In later technology, DVDs can store about 7 times more data than CDs and its format efficiency is also 32% higher than CDs.

What is Compact Disc?
A Compact Disc is an optical disk or a computer storage disk that stores data digitally, in computers, Compact Disc is a portable and secondary storage device commonly used as a CD.
History of CD-ROM
Compact disks are all used to protect digital data.
If we talk about its history, it was first developed in 1982 in partnership with Philips and Sony Company. When it was created, it was used only to preserve Audio Recording Data and later it was used in the Digital Data Store, at the same time it was upgraded in two forms -
1-CD-R
2-CD-RW
1-CD-R Compact Disc Readable
In this type of CD, we can only read the recorded data only once.
2- CD - RW Compact Disc Read / Write
In these types of CDs, we can both read / write the data.

If we talk about its structure and technology -

Media Type - Optical Disc
Encoding - Various Type
Storage Capacity - 700MB
Reading Capacity - 1200Kb (1x)
Writing Capacity - 1200Kb (1x)
How much data can be stored in CD?
By the way, Compact Disc comes in many sizes but the size of a normal CD is 4.7 in Capacity is 700 MB but it can store data up to 737 MB.
How to store data in CD
You know, the computer only understands the binary language. Optical disc CD ROM uses high intensity and low intensity laser beam to read the data to store the data in binary form.CD Writer is used to store data in a compact disc. High intensity laser rays when it falls on the CD make you pit on the CD and nowhere else where the pits are made, it represents 1 in the binary. And where the crater is not built, it is called land. It represents 0 in the binary. In this way the data is written to the CD. This data is now low intensity laser rays are used to read. The CD rotates on its track and the laser light comes in the pits and land in the CD. Reflects and comes back in this way, the light is converted into an electric signal and the data is read.
Important facts about CD
Prior to Compact Disc, a floppy disk was used as a secondary storage device, which was a Magnetic Storage. The storage capacity of a floppy disk was only between 1.44 megabytes to 2.8 megabytes whereas compact discs. The storage capacity is 700mb which can store around 800 floppy data.
Compact Disc is more popular than other magnetic devices because one could store more data in it and at the same time it was not easily damaged, they are very light and political and they can be used for long time Can be broken and kept once the CD is written, it can be used many times and even if light scratches are applied, your data is not T does not

Uses of Pen drive

October 05, 2019 0





Pen Drive Definition:-
A USB flash drive, also known as a thumb drive, pen drive, flash drive, memory stick, USB stick, or USB memory, is a data storage device that includes flash memory with an integrated USB interface.
 What is Pen Drive:-
It is usually removable, re-writable
and much smaller than optical discs. Most weigh less than 30 grams. Based on the Universal Serial Bus mass storage standard, USB flash drives are supported by all operating systems and BIOS. Compared to optical disk drives and floppy disks, USB flash drives can store more data and transfer it to fast speed.
The pen drive is nothing but a portable storage space device capable of taking care of your storage needs. Of course, in the earlier days, these devices were not able to store more than a hundred megabytes, but now, as technology has grown and is getting more and more complex, a pen drive can easily reach 120 GB and even more can store data.
The most impressive thing is that you will not need to carry a large external hard drive - you can store this information on a piece of plastic that is as big as your thumb nail.
Now, it is also notable that most pen drives are going to use flash technology. What is a flash pen drive? It is a USB storage device that takes advantage of a non-volatile device that is capable of storing your data even when it is not power sourced. However, it is also worth noting that the majority of currently produced pen drives are taking advantage of flash storage technology. Today specialized technology companies are working to improve pen drives and are trying to eliminate issues limiting its use. Many improvements have been made to the basic USB drive. We can use USB 3.0 pen drives nowadays, although USB 2.0's previous compatibility remains, and theoretically has a data transfer rate of up to 640 Mbps which is ten times faster than USB 2.0. Practically USB 3.0 pen drives with speeds up to 120 Mbps are readily available in the market. However for small files, this is limited to its actual speed of 10%.

USES OF PEN DRIVE:-
What are the uses of a pen drive?
USB flash drives are often used for the same purposes for which floppy disks or CDs were used; That is, storage, data back up and transfer of computer files. They are smaller, faster, have thousands of times more capacity, and are more durable and reliable because they have no moving parts.

Usage of USB pen drive
1) TRANSPORT:-
The most common use of USB pen drives is to transport or store personal files such as documents, pictures and videos.
2) COMPUTER REPAIR:-
USB pen drives are heavily used in the PC repair sector, such as installing antivirus software on PCs, Windows recovery, troubleshooting etc.
3) CARRY APPLICATIONS:-
USB pen drives are used to carry applications running on the host computer without the need for installation. Along with this, many applications of education are distributed from the pen drive itself.
4) AS AUDIO PLAYERS:-
Many companies make solid state digital audio players in a small form factor. The MP3 playback function is the most popular for USB pen drives. Some of them also have an LCD display and audio input jack and a rechargeable battery for browsing the track.
5) BOOT OPERATING SYSTEMS:-
Today most PC firmware allows booting from a USB drive, allowing you to boot PUSI from your pen drive. You can also perform OS recovery by creating recovery media.
6) OPERATING SYSTEM INSTALLATION:-
Many operating systems can be installed from Pen drive. You can install Windows 7, Windows 8, Linux, Mac OS etc. from a pen drive.
 7) BACKUP:-
Today pen drives are also used as backup.
A pen drive usually consists of a printed circuit board with a USB connector, power circuitry, and several integrated circuits (IC). One of these ICs on the PCB provides an interface between the memory and the USB connector.

The IC is next to a NAND flash memory where all files are stored. Pen drives or USB flash drives use PCBs as a means of transferring data and power from USB. The controller chip is considered the brain of the pen drive. The picture below shows the internal structure of the USB flash drive.

Types of printer

September 26, 2019 0

A printer is an online output device that prints the information received from the computer on paper. This copy of the output on the paper is called hard copy. The output of the information from the computer is very fast. And the printer could not work so fast, so the need was felt that the information can be stored in the printer itself, so the printer also has a memory from where it prints the results slowly.
"A printer is an output device that converts soft copy into hard copy."

 TYPES OF PRINTER
Printing Method: - The method of printing is a very important factor in printing. Printing method has two types of Impact Printing and Non-Impact Printing.

IMPACT PRINTING
Impact Printers are printers that leave their Impact, such as this method of typewriter printing, similar to the typewriter method that has a metal hammer or print head. This collides with paper and ribbon. In Impact Printing, characters or characters emerge on paper using the Solid Font or Dot Matrix method. There are several methods of Impact Printer. Like-

Dot Matrix Printer, Daisy Wheel Printer, Line Printer, Chain Printer, Drum Printer.
DOT MATRIX PRINTER
It is an Impact Printer so it makes a lot of noise while printing. The print head of this printer has a Matrix of several pins and each pin has a ribbon and a dot on the paper is printed by a dot. Several dots form a character together. The print head has a vertical group of 7, 9, 14, 18 or 24 pins. Horizontal group) Is the pin of one column at a time exits the print head Prints Dots so that a character is formed in several steps and the print head moves in the direction of the line Printing speed of Dot Matrix Printer 30 to 600 characters per second (CPS-Character Per Second) Dot Matrix Printer does not have pre-built currency characters, so it can print different size-type and character graphics (Graphics) etc. P With the help of a print head, we create characters which are obtained from memory in the form of codes (0 and 1). The print head contains an electronic circuit that decodes the character. Let's say that the print quality of this printer is not good.

DAISY WHEEL PRINTER
It is an Impact Printer with Solid Font, it is named Daisy Wheel because its print head shape resembles a Daisy Wheel Printer with a floral cauldron (Daisy).  Is a slow printer but the clarity of its output is high, so it is used for printing letters etc. and it is called Letter Quality Printer in its print head. A wheel is a wheel, in which a character's solid font is embossed in each spoke, the wheel moves in the horizontal direction of the paper and the printable character's spoke rotates in the wheel. A small hemmer arrives at the print position from the spoke ribbon and collides on the paper so that the letter is printed on the paper. These types of printers are now very little used.

LINE PRINTER
It is also an Impact Printer. Large computers require high speed printers. High speed printers can print one line page at a time instead of printing one character at a time. Speeds range from 300 to 3000 lines per minute. These printers are used for large tasks in mini and mainframe computers. Line printers are of three types.
Drum Printer, Chain Printer, Band Printer
DRUM PRINTER
A Drum Printer consists of a fast moving drum (Drum) on whose surface the characters emerge, a band (Band) is a set of all the letters (Set), many such bands on the entire drum Are so that the characters can be printed in each position of the line on the paper. The drums rotate rapidly and print a line in a rotation. A fast Hammer tuck against the paper on the appropriate character of each band. The expertise and are splash a line on a full rotation.
LAGER PRINTER
Laser printers are non-impact page printers. Laser printers have been in use in computer systems since the 1970s. They were first used in Mainframe Computer. In the 1980s, laser printers were worth about $ 3000. These printers are nowadays more are popular because they are capable of printing text and graphics in relatively fast and high quality. Most laser printers have an extra micro Processor (Ram) and ROM (Rom) are used, this printer also prints on paper only through dots, but these dots are very small and Due to the close proximity there are very clear prints. Cartridge is used in this printer, inside which the ink (ink) is filled in. The method of working of laser printer is basically like a photocopy machine. But in photocopying High light is used in the sheen. Laser Printer prints resolutions from 300 to 600 DPI (Dot per Inch) or even higher. Color laser printers provide high quality color output and have special toner in which particles of different colors are available, these printers are very expensive because their printing speed is high and it can print the output on the plastic seat or other seat.
PHOTO PRINTER
A photo printer is a color printer that prints on the quality photo paper of the photo lab. It can be used for printing documents. These printers have a large number of nozzles, which are very good inks for very good quality images. Prints drops.
