Both MAC Address and IP Address are used to uniquely identify a machine on the internet. MAC address is provided by the chip maker while IP Address is provided by the Internet Service Provider. Mac Address Media Access Control (MAC) address is a physical address that works at the data link layer of the OSI model. A MAC address is a 48 or 64-bit address associated with a network adapter. MAC addresses are linked to the hardware of the network adapters, hence they are also known as the "hardware address" or "physical address." MAC addresses uniquely identify the adapter ... Read More

Connection-oriented and Connection-less Services are used to establish connections between two or more devices. Connection-oriented Services A connection-oriented service is one that establishes a dedicated connection between the communicating entities before data communication commences. It is modeled after the telephone system. To use a connection-oriented service, the user first establishes a connection, uses it and then releases it. In connection-oriented services, the data streams/packets are delivered to the receiver in the same order in which they have been sent by the sender. Connection-oriented services may be done in either of the following ways − Circuit-switched connection: In circuit ... Read More

MMU and MPU are memory management hardware used by the CPU. The set of all the logical addresses generated by a program is referred to as a "logical address space". The set of all the physical addresses corresponding to these logical addresses is referred to as a "physical address space". The user program deals with virtual addresses; it never sees the real physical addresses. Read this article to learn more about MMU and MPU and how they are different from each other. What is MMU? MMU (Memory Management Unit) is used for virtual memory and memory protection operations. The runtime ... Read More

When several computers are connected together and are able to communicate with one another, it is called a computer network. Computer networks are designed to share data and information among the computers of the network. Depending on the operating geographical area, computer networks are of the three major types, namely LAN, MAN, and WAN. All the three computer networks are designed for the same purpose, i.e., for sharing information among the computers. But, they are different in many ways, which we are going to highlight in this article. Let's start with some basics of LAN, MAN, and WAN. What ... Read More

A WAN in general is a network of local area networks (LANs) that link to other LANs via telephone lines and radio waves. WAN connections can include both wired and wireless technologies. Wired WAN services include carrier Ethernet, commercial broadband Internet links, etc., whereas wireless WAN technologies include cellular data networks like 4G LTE, public Wi-Fi, satellite networks.LANs are privately owned and span a smaller geographical area (restricted to a few kilometers). It can be used in various settings, including offices, residences, hospitals, and schools. The setup and management of a LAN is quite straightforward.Go through this article to find ... Read More

It is the operating systems that play the most important role of creating interfaces between the machine and the user. There are two type of interface that the operating systems can create which are Graphical User Interface (GUI) and Character User Interface (CUI). The fundamental difference between GUI and CUI is that the GUI uses graphics to create the interface, while CUI uses text to create interface between the machine and user. Read this article to find out more about GUI and CUI based systems and how they are different from each other. What is GUI? GUI stands for ... Read More

Both Blue-Ray Disk and DVD are the optical type secondary storage devices used in computer systems. We are all familiar with DVDs, but Bluray discs are relatively new data storage devices. Blue ray discs give a better visual experience with high video resolution. In this article, we will discuss the important differences between Blue-Ray Disc and DVD. But before going into the differences, let's start with some basic concepts of these two storage devices. What is Blu-Ray? BluRay Disk (BD) is an optical storage media used to store high definition (HD) video and other multimedia filed. BD uses shorter wavelength ... Read More

CRT and LCD are both display devices. CRT is an old technology whereas LCD is modern one. One major difference between CRT and LCD is in the technology used for image formation. The CRT display produces an image by using an electron beam, while LCD display produces an image on the screen using liquid crystal display. What is a CRT? CRT stands for Cathode Ray Tube. CRT displays produce an image on the screen by using a sharp beam of electrons that is highly focused to hit a phosphor screen present in front of the tube. The important components of ... Read More

After the launch of the first generation mobile network in the early 1980s, the mobile wireless communication system has gone through numerous stages of evolution in the last several decades. Because there was such a high demand for new connections throughout the world, mobile communication standards progressed quickly to accommodate more users. In this brief article, let's have a look at the features offered by the early generation mobile standards.1G ProtocolThe first generation of wireless cellular technology is referred to as 1G. These are analog telecommunications standards that were launched in the 1980s and lasted until 2G digital telecommunications superseded ... Read More

In computer programming, the concept of reusable code refers to the utilisation of previously developed software in the construction of new software. Reusability of code is recognised as an essential component of productive functionality. Establishing associations between classes is one method that object-oriented programming uses to encourage this.In object-oriented programming, there are two primary ways to construct these relationships: inheritance and composition.In object-oriented programming (OOP), inheritance refers to the process through which an object can take on the properties of one or more other objects. In OOP, it is one of the most powerful concepts for establishing code reusability. When ... Read More
