During the past two decades, cutting-edge technologies such as artificial intelligence, machine learning, and computer vision have made the transition from the realm of research and development into the commercial and mainstream spheres. The commercial use has resulted in automated robot industrial assembly lines, automated vehicle navigation systems, and the analysis of remotely collected imagery to support automated visual inspection procedures.Applications of computer vision and machine learning are some of the most enticing and exciting areas of study in the field of technology in the modern day. In addition, the majority of current tech sector corporations as well as ambitious ... Read More

The human eye has six and seven million cone cells, each of which contains one of three different types of opsins, which are proteins that are sensitive to color. When photons of light strike these opsins, they transform, setting off a cascade that produces electrical signals, which then send the messages to the brain so that they can be interpreted.Making a machine that can read this on a level that is understandable to humans has always been a difficult task because the process as a whole is so complicated. Emulating human vision in terms of recognizing patterns and faces, as ... Read More

Before discussing the above categories, let's define computer memory. The data is kept as 0s and 1s so the user can save and retrieve it. Memory is like a person's brain. Computer memory allows speedy data access. The CPU may talk to the application faster. Without computer memory, the user couldn't save anything.Computer memory stores data either temporarily or permanently, based on which it is classified as either primary (internal memory) or secondary (external memory).There are two types of memory −External Memory − Most of the time, external memory means storing files on an external hard drive or on the ...

Although interrupt and exception are two distinct ideas, they are related in the sense that they both force the central processing unit (CPU) to halt the normal flow of execution of instructions and instead begin executing another programme in the kernel space in order to deal with the issue at hand. This is true even though interrupt and exception are distinct ideas. The primary distinction lies in the manner in which they deal with unforeseen occurrences that may take place anywhere in the system, the processor, or even within the programme itself.What is an Interrupt?An interruption is a signal that ...

Text is composed of individual characters, which are combined to form words and sentences. Characters that are needed for a specific purpose are grouped into a character set. Each individual character is assigned a number, which is referred to as a code point, so that there is no room for ambiguity when referring the characters.The computer saves each character as one or more bytes, depending on the size of the character. You can get a general idea of how this works if you assume that every character in a computer is represented by a unique code, similar to the cyphers ... Read More

Let us understand the concepts of Fastag, Bar code, QR code and Near Field Communication (NFC).FastagFASTag is an electronic scanner system used for toll collection in India, which is operated by the National Highway Authority of India. It is based on radio frequency identification (RFID) technology. FASTag is fixed on the windscreen of vehicles. FASTags does not have any expiry date. They can be recharged at any time.Working of FASTag systemVehicles with FASTag enabled do not have to stop at toll gates where charges are deducted from the prepaid or bank account when the vehicle is moving. The drivers do ... Read More

Let us understand the concept of barcode and Quick Response (QR) code.Bar CodeA bar code reader decodes the data contained in the barcode and sends it to the computer. It produces a beam of light or a laser beam to read barcodes which is reflected by the bar code image. A light sensitive detector which is present in the reader identifies the bar code by recognizing special bars on both ends of the image. With the help of these special bar’s reader is able to identify whether the bar code has been read right side up or upside down.Once a ... Read More

The full form of ARPANET is Advanced Research Projects Agency NET was developed under the direction of the US Advanced Research Projects Agency and was based on a concept first published in 1967. With the interconnection of four university computers in 1969, the concept became a modest reality.It was the first network to implement the TCP/IP protocol. It was a very early packet switch network. This network became the foundation for the modern day internet.The protocols used in Arpanet were later developed for joining multiple networks, which gave rise to the modern day internet. It helps in grouping the data ... Read More
