3. Advantages of the hard disk over a floppy disk
4. Limitations of the hard disk over a floppy disk

Types of floppy disk

A floppy disk is basically a computer component that has designed to read as well as write to the floppy disk that was used for removable storage. The most popular type of floppy disk drive is the 3 and 1/2 inch drive which nowadays limited use for today. The first floppy disk that came in the market were in 8 inches in diameter. This disk was protected by a flexible plastic jacket. An 8-inch disk back in the late 1970s could store data in 1 MB. In 1980 the 3.5-inch floppy or called micro floppy came on the market and this type became the dominant storage medium for personal computers for many years. 

Floppy disk was quite vulnerable. This disk is medium was very sensitive to dust, heat, and moisture. As we know that the flexible plastic carrier was also not very sturdy. The hard plastic case of the 3.5-inch floppy disk was presented a substantial improvement in this respect. The most common format of this floppy became the double-sided and high density 1.44 MB disk drive.

Nowadays floppy disk drive has been replaced by other types of such that DVD drives, CD drives as well as USB flash drives. They are many different types of floppy disk drives that have come and gone over the years.


Conclusions:

According to the size, the floppy disk is generally called into two:

  • 3.5-inch diskette
  • 5.25-inch diskette
  • A normal 3 and 1/2-inch disk can store 1.44 megabytes of data.
  • Zip data - The part of  Zip drives were introduced by the Iomega corporation in the mid-year of -the 1990s. A zip disk was capable of storing 100 megabytes, 250 megabytes, 250 megabytes and even 750 megabytes on a single disk. Zip drives were mainly available as a peripheral that could be added to an existing system.

Difference Between LVDS and TTL

LVDS stands for low voltage differential signalling while in TTL stands for Transistor-transistor logic. Both of them are signalling types used as the most common data transmission. Conversion between TTL to LVDS and LVDS to TTL is possible though they have incompatible interfaces. Here this page gives the LVDS vs TTL also gives the main key difference between LVDS and TTL are listed below.

Difference between LVDS and TTL :

  • LVDS stands for low voltage differential signalling while in TTL stands for Transistor -transistor logic.
  • LVDS uses two wires voltage difference between the two which determines whether the data is zero or one while in TTL is uses the presence or absence of voltage with reference to the ground which determines binary 1 or 0.
  • LVDS can uses lower voltage levels than TTL.
  • LVDS is a lot more resistant to interference than the TTL logic device. So TTL support less resistance,
  • Power consumption is less in LVDS but in TTL power consumption is more.
  • LVDS support higher transmission distance, TTL support lower transmission distance.
  • LVDS does not use the ground as a reference signal while TTL uses the ground as a reference signal.
  • Devices that use LVDS can have uses longer wires than devices that use of TTL logic devices.
  • LVDS and TTL are not compatible but they can be converted.
  • TTL uses the ground as a reference while LVDS doesn't.
  • LVDS  support serial mode transmission, TTL mode uses parellel mode tramsmission.
  • LVDS uses twisted pairs that form tight EM field coupling. Hence differential voltage due to voltage spikes will remain the same and will not be affected during transmission due to o any EMI. These are the major benefits of LVDS. TTL based data transmission, a binary zero may become binary one when it reaches the receiver due to voltage spike. Thus it is the demerits of TTL over LVDS signalling.

Difference Between SMS and IM

In today's digital world, people are using high-speed communications, getting instant information, Instant message to get there are two common ways of getting your messages across quickly vis using short message services and IM called as an instant message service. SMS has been around much longer than instant message apps like facebook, WhatsApp, skype, etc. The main difference between the SMS and IM is that in SMS you can leave a short message even if the person does not answer his phone while in IM is predominantly used in personal computers thus IMs utilize the internet for passing its message.  Here this page gave the basic comparison between SMS and IM to understand this topic clearly.

Difference between SMS and IM :

  • SMS  stands for short message service while IMs stand for Instant messages.
  • Both methods are popular for communication, both allow to message to send across to another person.
  • As we know that the SMS goes through the telephone company's network while an IM goes through the internet.
  • As in some cities will be decided on SMS that SMS is limited 160 characters while IM will not be decided character criteria.
  • There are many companies are available and they provide a different plan for SMS so they provide limited or unlimited access to the message but in IM are generally free, as long as you have a connection to the internet, IM is generally free, but as long as you have a connection to the internet.
  • In today's world, SMS costs money while IM is virtually free.
  • An SMS is typically limited by country, and some extra charge for pother country to send SMS while in IM is limited by software.
  • SMS will are so useful as well as also some drawbacks because unlike SMS there IMs need to the internet connection to the function, this is a drawback to their services but you can send an SMS anywhere, anytime to anyone without the internet connection. Also, the receiver need not be pre-install the app. IN all mobile companies provide the SMS feature but there some costs involved to send out the SMS if you don't have some special packages.

 Both the SMS and IM while different but have the use the same purpose. Both are used to provide a method for people to connect to each other via using SMS or IM. today digital world both teenagers as well as young adults some might even say misused. 

 We hope that you have got a better understanding of this concept. Furthermore, any quires regarding this concept or some electrical and electronics projects give your feedback in the comment section below.

Difference between Circuit Switching and Packet Switching

The main difference between circuit switching and packet switching is that the circuit is connection-oriented whereas packet switching is that connectionless. Circuit switching and packet switching are two switching methods that are used to connect the multiple communicating devices with one another. Circuit switching was particularly designed for voice communication technology and also it was less suitable for data transmission path. Let us learn some more comparison between circuit switching and packet switching with the help of comparison are given below.

Difference between circuit switching and packet switching


  • In-circuit switching there are 3 phases: 1 is called connection establishment 2nd is data transfer and third is connection released while in packet switching directly data transfer takes place.
  • Circuit switching is connection-oriented while in packet switching is connectionless. 
  • In-circuit switching a single connection which also leads to a single path for establishing a connection between two points while in packet switching a packet is simply data that has been divided into some smaller units along with a header, for ease of transfer containing signal information. 
  • In-circuit switching each data unit knows the entire path address which is provided y the source while in packet switching in each data unit just know the final destination address intermediate path is decided by the routers.
  • A circuit needs to be established to make sure that the data transmission takes place while in packet switching each packet containing the information that needs to be processed goes through the dynamic route.
  • While we have to use circuit switch a uniform path is followed throughout the session while in packet switching there is no uniform path that is followed end to end through the session.
  • Circuit switching is most ideal for voice communication while also keeping the delay uniform but in packet switching mainly used for data transmission as the delay is not uniform.
  • In-circuit switching, without a connection it can't exist as the connection needs to be present on a physical layer, but the packet switching is not necessary, as it can exist without one too. It needs to be present on a network layer. So in Circuit switching is implemented by the physical layer while in packet switching is implemented by the network layer.
  • Packet switching is store and forward technique while in circuit switching is not store and forward technique
  • Circuit switching is more reliable but packet switching is less reliable.
  • In packet switching less wastage of resources as compared to circuit switching so in circuit switching wasted resources are more.
  • Congestion can occur during the connection is establishment time there might be a case will requesting for the channel is already occupied while in packet switching congestion can occur during the data transfer phase, a large number of packet comes in no time.
  • Circuit switching can be achieved using two technologies either the space division or time division switching while in packet switching has two approaches datagram approach and virtual circuit approach.

Differences Between LED Bulbs and LED Fixtures

What are the LED bulbs?


 LED stands for light-emitting diode, this is a light source is similar to fluorescent, incandescent, and CFL lighting. The LED lamp is energy saving which is typically in the range of 25% to 85%, depending on which type of lamp that is replaced.

What are LED fixtures?


 LED fixtures are similar in design to traditional lighting fixtures.  They are specially designed to work with LED light bulbs,  whereas some traditional fixtures are incompatible with LEDs.

 The basic key difference between led BULB and LED fixtures are given below. 

Physical Design


The LED bulb looks similar to traditional fluorescent, incandescent, and CFL bulbs, they are a variety of sizes available mow days and it usually interchangeable with traditional light bulbs. The LED has much more common which is to say a fair number of businesses and a handful of households are using them. 

While LED fixtures come in a wide array of sizes, shapes, and styles. They are as varied as traditional lighting fixtures and it can be used both indoors and outdoors depending on the materials making up the fixtures. Fixtures may come with LED bulbs in place or the bulbs may need to be bought separately.

Average lifetime 


The average life span of an LED bulb is around 20000hours. This is significantly longer than the life span of traditional bulbs. The light bulb that has lit up our homes since the 1800s is officially on its way out. 

While in LED fixtures is should be last for many years. as long as it is kept safe from any weather or wear and tear it is not designed to withstand. 

Cost 


The cost of an LED bulb is typically more expensive than comparable to the incandescent bulbs. 

While in LED fixtures are much more expensive than simply buying replacement bulbs. It may be cost for installation and supporting hardware along with the expense of the fixture itself. 

Size


The LED bulb's size is to be small.

While in LED fixtures size must be varied, it may vary larger than bulbs.

Ease of installation


Most of the LED bulbs are interchangeable with some traditional light bulbs, so they can simply be swapped into an existing lamp or fixture. The LED bulb is also easy to uninstall and replaces as they only need to be unscrewed by hand from the connections. 

LED fixtures should be thought of as physical updates to a home or building. Unless the fixture is a standalone lamp, it will most likely need to be properly attached to a ceiling or wall using hardware and tools. When installing some new fixtures is much more complex than replacing an old light bulb with LED one but this method allows for greater design customization and lighting options.
