The Intel 8279 is a keyboard/display controller that interfaces keyboard and display devices with the microprocessor-based system. Through the use of this controller, processor utilization reduces in correspondence to time-consuming tasks such as keyboard scanning and display refreshing. Basically, it is a general-purpose controller that performs the function of driving the display unit as well …
RISC is an acronym for Reduced Instruction Set Computer. The RISC processor is a type of microprocessor that operates on small but very optimized instruction sets in order to perform various tasks. It is based on one instruction per cycle approach. RISC is considered to be an alternative to CISC (Complex Instruction Set Computer) which …
Pentium Microprocessor is one of the powerful family members of Intel’s Χ86 microprocessor. It is an advanced superscalar 32-bit microprocessor, introduced in the year 1993 that contains around 3.1 million transistors. It has a 64-bit data bus and a 32-bit address bus that offers 4 Gb of physical memory space. While the maximum clock rating …
In ARM Processors, ARM is an acronym used for Advanced RISC Machines as these are a family member of those CPUs which are based on RISC architecture. More simply, Advanced RISC machines have created the architecture of ARM processors thus called so. These processors offer architectural simplicity due to which it exists in small size, …
RFID Technology is an abbreviation used for Radio Frequency IDentification technology. RFID technology is a unique mode that offers automatic identification and tracking of objects or entities by making use of radio-frequency waves. This technology is known to be a combination of radio broadcast technology and radar. In the 1980s, it has gained immense popularity …
Remote Sensing is defined as an art or science of observing and gathering information about any object, scene, or phenomenon which exists at a remote location from the point of observation. The word ‘remote’ is used in reference to the existence of something (object of interest) at a distant location or the one which is …
Satellite Internet is regarded as a network of networks that uses satellites to interconnect the various segments of the network so as to enable communication between devices present at distant locations. Through satellite internet nationwide coverage can be obtained. Basically, there is no physical structure of the internet on its own rather, it uses satellite …
Satellite Networks are defined as the orientation of various elements that establish communication through various nodes from one point of the earth to another point. Any satellite network can provide both types of transmission technologies i.e., point to point as well as broadcasting connections. When we talk about a network through which data is transmitted …
Satellite Communication is defined as a type of communication where the exchange of information takes place between different stations present on the surface of the earth using artificial satellites in space. And this communication occurs within the electromagnetic spectrum. So, in simplest terms we can say when communication between two or more ground-based units is …
Radio Wave Propagation deals with the behaviour of radio waves when the waves travel from one end to another. It is sometimes known as simply wave propagation or propagation of electromagnetic waves. Radio wave transmission is a quite prominent method by which information can be transferred from one end to another. Radio wave propagation is …
