HTML Full Form, What is HTML?

 

HTML full form Hyper text markup language

HTML is a low level programming language that is used for creating web pages and websites. The all websites we see today on internet are created using HTML, CSS, and JavaScript. HTML is used for writing text, Image, Video and adds tags and all visible content on the Web. By using HTML we can simply create a responsive webpage.

CSS is used for styling and making up the content on the web. Using CSS, we can add different effects on our webpage. And we can make our site even more beautiful. If the CSS of site is correct and also HTML codes, then the page will be responsive and attractive.

Another is JavaScript, by using JavaScript you can create working search button you can also add the commands on the webpage using JavaScript. Eg: If person visited your site, then after specific time, that person will receive this message or this text. Such that, the site looks too good and easier

These three languages (HTML, CSS, and JavaScript) are the easiest languages to learn at start coding. Even 7–8 years child can start learning this language and can start web development at 10th or 11th year.

Various web companies are today hiring the people with the professional skills of HTML.

USB Full Form, What is USB?

USB full form Universal Serial Bus.

The “Universal” means that the bus itself, and controllers for the bus don’t really care about what the data is, and only concern themselves with transmission of the data, and capabilities of hardware on both ends of transmission. RS-232 and LP both tended to bog down hardware on having to do VERY specific things with their data and how it is communicated, whereas USB is designed to abstract that through controllers that just want to know what’s going in and going out, simplifying the addressing and signaling requirements of hardware and driver designers significantly as they can just ignore signal implementation details.

The “Serial” is because the data is transmitted one piece at a time. This may seem like it would be slower than a parallel bus, and in theory it would be, but one of the biggest flaws in a parallel bus is that hardware has to be designed to input and output each bit on its own line, making it more complicated to design and more expensive in the end. Serial interfaces, especially USB, are very fast now despite having to shift bytes one bit at a time, normally.

The “Bus” is, well, because it’s a bus. It’s a common signal interconnect between hardware used to send and receive data. What’s nice about USB is that it’s a bus that extends itself externally from the computer in an addressable, tree-like manner, meaning multiple devices can connect via one physical port on the machine, and there should be no conflict. Arguably the old serial or parallel connections are not buses, as they weren’t really addressable beyond what port on the computer is used, though in theory a device and device driver could be written for those to make a sort of bus-like protocol. Typically the old standards were designed with the idea that ONE device used that connection and thus every signal going in and out was meant for that one device, which to me means they weren’t bus standards.

ROM Full Form, What is ROM?

ROM full form Read Only Memory.

The memory from which we can only read but cannot write on it, this type of memory is non-volatile. The information is stored permanently in such memories during manufacture. A ROM stores such instructions that are required to start a computer. This operation is referred to as bootstrap. ROM chips are not only used in the computer but also in other electronic items like washing machine and microwave oven.

Types of ROMs and their characteristics

MROM (Masked ROM)

The very first ROMs were hard-wired devices that contained a pre-programmed set of data or instructions. These kinds of ROMs are known as masked ROMs, which are inexpensive.

PROM (Programmable Read Only Memory)

PROM is read-only memory that can be modified only once by a user. The user buys a blank PROM and enters the desired contents using a PROM program. Inside the PROM chip, there are small fuses which are burnt open during programming. It can be programmed only once and is not erasable.

EPROM (Erasable and Programmable Read Only Memory)

EPROM can be erased by exposing it to ultra-violet light for duration of up to 40 minutes. Usually, an EPROM eraser achieves this function. During programming, an electrical charge is trapped in an insulated gate region. The charge is retained for more than 10 years because the charge has no leakage path. For erasing this charge, ultra-violet light is passed through a quartz crystal window (lid). This exposure to ultra-violet light dissipates the charge. During normal use, the quartz lid is sealed with a sticker.

EEPROM (Electrically Erasable and Programmable Read Only Memory)

EEPROM is programmed and erased electrically. It can be erased and reprogrammed about ten thousand times. Both erasing and programming take about 4 to 10 ms (millisecond). In EEPROM, any location can be selectively erased and programmed. EEPROMs can be erased one byte at a time, rather than erasing the entire chip. Hence, the process of reprogramming is flexible but slow.

The advantages of ROM are as follows −

·         Non-volatile in nature

·         Cannot be accidentally changed

·         Cheaper than RAMs

·         Easy to test

·         More reliable than RAMs

·         Static and do not require refreshing

·         Contents are always known and can be verified

OTP Full Form, What is OTP?

OTP full form One-Time Password

A one-time password (OTP), also known as one-time pin or dynamic password is a password that is valid for only one login session or transaction, on a computer system or other digital device. OTPs avoid a number of shortcomings that are associated with traditional (static) password-based authentication; a number of implementations also incorporate two-factor authentication by ensuring that the one-time password requires access to something a person has (such as a small keyring fob device with the OTP calculator built into it, or a smartcard or specific cellphone) as well as something a person knows (such as a PIN).

Advantages:

The most important advantage that is addressed by OTPs is that, in contrast to static passwords, they are not vulnerable to replay attacks. This means that a potential intruder who manages to record an OTP that was already used to log into a service or to conduct a transaction will not be able to abuse it, since it will no longer be valid. A second major advantage is that a user, who uses the same (or similar) password for multiple systems, is not made vulnerable on all of them, if the password for one of these is gained by an attacker. A number of OTP systems also aim to ensure that a session cannot easily be intercepted or impersonated without knowledge of unpredictable data created during the previous session, thus reducing the attack surface further.

OTPs have been discussed as a possible replacement for, as well as enhancer to, traditional passwords. On the downside, OTPs are difficult for human beings to manipulate. Therefore, they require additional technology to work.

PIN Full Form, What is PIN?

PIN full form POSTAL INDEX NUMBER

PIN - Postal Index Number (In case of Indian Post which is used generally in address)

There are many types of PIN but basically we use frequently two pin our daily life first is for indicating someone's address which is known as POSTAL INDEX NUMBER and secondly we use in ATM to identify some person in banking process which is known as PERSONAL IDENTIFICATION NUMBER.

Personal Identification Number (PIN) is a secret numerical code allocated to a user that can be used to authenticate the user to a secured system. A PIN is used to validate electronic transactions across multiple sectors, including banking, payment processing, and communications.

It is used as a password in several entities including ATM Card, Debit Card, Credit Card, Mobile SIM card etc. It is the number which is hidden from the manufacturer or provider of a card and is known only to the user.

SIM Full Form, What is SIM?

SIM full form Subscriber Identification Module.

The account holder is the subscriber. The cellular network uses the ID provided by the SIM to identify what phone number will be connected to a phone carrying that SIM card. The SIM card also identifies its issuing network, and when roaming in different countries, the foreign networks will use this identification to establish whether they will support the card or not. When roaming, the SIM will retain the phone number that is linked to it and will act as though it is in the country for its home network.

Move the SIM card to another phone, and that other phone will take over the phone number. This is subject to the new phone being compatible physically (there are different sizes of SIM card), and the phone is not blocked from working with the network used by the SIM.

How to port SIM:

If the subscriber moves to a different network, the new network will issue a replacement SIM. The phone number may be ported from the old SIM to the new one. Note: the old account must not be closed down before the number is transferred or the number may be lost. You should also note that the phone may be blocked from accepting a SIM from a different network. If necessary, the block can normally be removed although a charge may be payable for this service.

DSLR Full Form, What is DSLR?

DSLR full form Digital Single-Lens Reflex

A digital single-lens reflex camera is a digital camera that combines the optics and the mechanisms of a single-lens reflex camera with a digital imaging sensor, as opposed to photographic film.

DSLR is an abbreviation of digital single-lens reflex.

During the 2000s, DSLRs highly replaced film-based SLRs, and in the early 2010s, regardless of the rising acceptance of mirrorless system cameras, DSLRs persists the most general type of interchangeable lens camera in use.

In 1975, Steven Sasson the Kodak engineer developed the first digital still camera, which used a Fairchild 100×100 pixel Charge-Coupled Device.

Components of DSLR Camera

Following are the main components of a DSLR camera,

·         Lens

·         Reflex mirror

·         Shutter

·         Image sensor

·         Matte focusing screen

·         Condenser Lens

·         Pentaprism

·         Eyepiece/Viewfinder

Working of DSLR

·         Through a medium of lens, light enters the camera and collides with the reflex mirror.

·         The reflex mirror throws back the light to the focusing screen in the vertically upward direction.

·         The passing of light happens through focusing screen and it enters the block of a glass which is a Pentaprism.

·         Pentaprism directs the light towards different direction through two discrete mirrors then redirects it towards viewfinder.

·         The viewfinder provides a user the live preview of the image.

·         The reflex mirror overturns upward and obstructs the vertical path of light to keep it directed towards image sensor, when a user clicks the button to take an image.

·         The light reaches the image sensor, when the shutter opens up.

Advantages of DSLR

·         Speed and picture Quality will be good

·         Interchangeable lenses

·         Optical Viewfinder

·         Large ISO range

·         Easy editing and low noise

·         Faster focusing and high quality in low light

·         Ability to use filters

·         Dust removal system

Disadvantages

·         Size is large and weight is heavy

·         Strenuous in accomplishing simple tasks

·         Hard to carry during shoot

·         Complicated in settings

·         Cost is higher
