Before we get to the offset printing machine let's first understand what is offset printing all about. In offset printing, the image or text that is to be printed needs to be transferred from a metal plate to a rubber blanket which is mounted on heavy iron rollers. This roller is one of the most important parts of the offset printing machine as it is that component of the machine which does the printing. "Offset" is a technical term which is meant to convey the process by which the image is transferred from the metal plate to the rubber blanket ... Read More

Proper security involves all-around surveillance or observation of people, their behavior and actions, immovable property like land and building as well as movable property stationed there. Surveillance is generally conducted with the help of methods that either have limited mobility or are stationary like, CCTV cameras, GPS tracking dependent on satellite connectivity and not helpful in close observation, stake-outs, which are time-consuming, data-based profiling and biometrics and some other methods.Drone Has Turned the TableAll these methods have their own level of advantages and limitations but when it comes to drone technology, the efficiency, and effectiveness of any security operation increase ...

Career prospects in the VFX (Visual Effects) industry are enormous, especially in a country like India which not only has a huge domestic market for VFX-enriched content in its mass media entertainment programs but is also a massive base for VFX job work for the global entertainment industry.The Right SoilIndia has the right eco-system to provide high-quality VFX output at an affordable cost and at scale. VFX requires the animators to be creative, imaginative, skilled in application software and willing to work long hours and at wages that very few other countries can match. So, yes, the opportunities in VFX ... Read More

After machine level language, the next level of development in the evolution of computer languages was the Assembly Language. Machine level language uses only the binary language. But on the other hand, assembly language uses mnemonics or symbolic instructions in place of a sequence of 0s and 1s. As example, we can consider that, to add register A and B in a particular computer, assembly language uses the mnemonic ‘ADD B’ in place of 10001111. In assembly language, we use symbolic names to denote addresses and data. A number of such examples are dealt with in the successive chapters. Thus ... Read More

A Microcontroller is a small and low-cost microcomputer, which is designed to perform the specific tasks of embedded systems like displaying microwave’s information, receiving remote signals etc.The general microcontroller consists of the processor, the memory (RAM, ROM, EPROM), Serial ports, peripherals (timers, counters) etc.Types of MicrocontrollersMicrocontrollers are divided into various categories based on memory, architecture, bits and instruction sets. Following is the list of their typesBit − Based on bit configuration, the microcontroller is further divided into three categories.8-bit microcontroller  − This type of microcontroller is used to execute arithmetic and logical operations like addition, subtraction, multiplication division, etc. For ...

The processor on a single chip is called a Microprocessor which can process micro-instructions. Instructions in the form of 0s and 1s are called micro-instructions. The microprocessor is the CPU part of a microcomputer, and it is also available as a single integrated circuit. Thus as main components, the microprocessor will have the Control Unit (CU) and the Arithmetic Logic Unit (ALU) of a microcomputer. An example is Intel 8085 microprocessor. In addition to the microprocessor features, a microcomputer will have the following additional features −ROM / PROM / EPROM / EEPROM for storing programRAM for storing data, intermediate results, ...

A microcomputer can be defined as a small sized, inexpensive, and limited capability computer. It has the same architectural block structure that is present in a computer. Present-day microcomputers are having smaller sizes. Nowadays, they are of the size of a notebook. But in coming days also their sizes will get more reduced as well. Due to their lower costs, individuals can possess them as their personal computers. Because of mass production they are becoming still cheaper. Initially in the earlier days they were not very much powerful. Their internal operations and instructions were very much limited and restricted. But ... Read More

CPU and the main memory are having speed faster compared to the electromechanical input or output devices like printers, mouse etc. In such a case it is essential that the data lines of the computer should not kept engaged for a long time during communication with input/output (I/O) devices. Otherwise as an effect, the overall speed of the computer system comes down drastically. So I/O devices are connected to a computer through I/O ports.For example, to get a document printed by the printer, phase wise printer will get required information from the CPU to carry out the printing process. After ... Read More

Whenever a program executes inside a computer then at first the program has to be loaded on to the computer’s primary memory. And also when a does not execute then also the program must remain loaded in computers secondary memory. This memory unit works as an extra block. In a program in memory, the entire set of performed operations is written using the keyboard as a sequence of instructions. This collection of instruction is called a program. Also, the data on which the program is to operate is entered with the help of the keyboard and can be stored in memory. ... Read More

Output devices are used for displaying or recording the results computed by the computer. Most common output devices are the CRT display,  printer, and plotter.Following are some of the important output devices used in a computer.MonitorsGraphics PlotterPrinterMonitorsMonitors, commonly called a Visual Display Unit (VDU), are the main output device of a computer. It forms images from tiny dots, called pixels that are arranged in a rectangular form. The sharpness of the image depends upon the number of pixels.There are two kinds of viewing screen used for monitors.Cathode-Ray Tube (CRT)Flat-Panel DisplayCathode-Ray Tube (CRT) MonitorThe CRT display is made up of small picture elements ...
