                           video --- Whether you work in a wired network office or a wireless one, one thing is common for both environments: It takes both network software and hardware (cables, routers, etc.) to transfer data from your computer to another—or from a computer thousands of miles away to yours. And in the end, to get the data you want right to YOU, it comes down to addresses. So not surprisingly, along with an IP address (which is networks software), there's also a hardware address. Typically it is tied to a key connection device in your computer called the network interface card, or NIC. The NIC is essentially a computer circuit card that makes it possible for your computer to connect to a network. An NIC turns data into an electrical signal that can be transmitted over the network. Hey Nick. Meet Mac. Every NIC has a hardware address that's known as a MAC, for Media Access Control. Where IP addresses are associated with TCP/IP (networking sof

video -------                                         A network  host  may offer information resources, services, and applications to users or other nodes on the network. A network  host  is a network node that is assigned a network  address . Computers participating in networks that use the Internet protocol suite may also be called  IP hosts . How do I find my host address? To find your Host Name and Physical Address using the Windows Command Prompt: Open the Command Prompt window by clicking on Start > (All) Programs > Accessories > Command Prompt. ... Type ipconfig /all and press the Enter key. What is the host machine? A hypervisor or virtual  machine  monitor (VMM) is computer software, firmware or hardware that creates and runs virtual  machines . A computer on which a hypervisor runs one or more virtual  machines  is called a  host machine , and each virtual machine  is called a guest  machine . What is the difference between a network a

                   video ---- No doubt you've heard the term "IP address." Unless you're a techie, though, you may not have more than a shadowy notion of what an IP address actually is or how it works. Let's explore the concept. An IP address is a fascinating product of modern computer technology designed to allow one computer (or other digital device) to communicate with another via the Internet. IP addresses allow the location of literally billions of digital devices that are connected to the Internet to be pinpointed and differentiated from other devices. In the same sense that someone needs your mailing address to send you a letter, a remote computer needs your IP address to communicate with your computer. "IP" stands for Internet Protocol, so an IP address is an Internet Protocol address. What does that mean? An Internet Protocol is a set of rules that govern Internet activity and facilitate completion of a variety of actions on the

                                     video --- The Domain Name System (DNS) is one of the foundations of the internet, yet most people outside of networking probably don’t realize they use it every day to do their jobs, check their email or waste time on their smartphones. At its most basic, DNS is a directory of names that match with numbers. The numbers, in this case are IP addresses, which computers use to communicate with each other. Most descriptions of DNS use the analogy of a phone book, which is fine for people over the age of 30 who know what a phone book is. If you’re under 30, think of DNS like your smartphone’s contact list, which matches people’s names with their phone numbers and email addresses. Then multiply that contact list by everyone else on the planet. When the internet was very, very small, it was easier for people to correspond specific IP addresses with specific computers, but that didn’t last for long as more devices and people joined the gro

VIDEO--- Hypertext Transfer Protocol (HTTP)  is a method for encoding and transporting information between a client (such as a web browser) and a web server. HTTP is the primary protocol for transmission of information across the Internet. Information is exchanged between clients and servers in the form of Hypertext documents, from which HTTP gets its name. Hypertext is structured text that uses logical links, or  hyperlinks , between nodes containing text. Hypertext documents can be manipulated using the Hypertext Markup Language (HTML). Using HTTP and HTML, clients can request different kinds of content (such as text, images, video, and application data) from web and application servers that host the content. HTTP follows a request-response paradigm in which the client makes a request and the server issues a response that includes not only the requested content, but also relevant status information about the request. This self-contained design allows for the distributed

System software  is software on a computer that is designed to control and work with computer  hardware . The two main types of system software are the  operating system  and the software installed with the operating system, often called  utility  software. The operating system and utility software typically depend on each other to function properly. Some system software is used directly by users and other system software works in the background. System software can allow users to interact directly with hardware functionality, like the  Device Manager  and many of the utilities found in the  Control Panel . Software that allows users to create documents (e.g.,  Microsoft Word) , edit pictures (e.g.,  Adobe Photoshop) , browse the Internet (e.g.,  Microsoft Internet Explorer ), or check their e-mail (e.g.,  Microsoft Outlook ) are considered  application software . System software does not involve direct interaction with computer hardware or operating system functionality, but

Key Difference:   Software refers to a set of programs which is capable of performing some specific tasks on a computer system. They can be broadly classified into two categories - System software and Application software. Software refers to computer programs which perform specific functions as instructed.  It can be a single program or may refer to a number of programs collectively. These instructions are defined in proper step by step manner. It is important to mention that hardware becomes incapable for extending its capabilities without support of the software. These software programs assist computer systems and network to start and work. Software are broadly classified into two categories – System Software  – This software is usually engaged in background processes. This software sync the work of hardware and other types of programs. It acts as a middle layer between hardware and user applications. System software includes programs like – Operating system  –

Definition:  Software engineering is a detailed study of engineering to the design, development and maintenance of software. Software engineering was introduced to address the issues of low-quality software projects. Problems arise when a software generally exceeds timelines, budgets, and reduced levels of quality. It ensures that the application is built consistently, correctly, on time and on budget and within requirements. The demand of software engineering also emerged to cater to the immense rate of change in user requirements and environment on which application is supposed to be working. Description:  A software product is judged by how easily it can be used by the end-user and the features it offers to the user. An application must score in the following areas:- 1) Operational: -This tells how good a software works on operations like budget , usability, efficiency, correctness ,functionality , dependability , security and safety. 2) Transitional: - Transitional

Sometimes abbreviated as  SW  and  S/W ,  software is a collection of  instructions  that enable the user to interact with a computer, its hardware, or perform tasks. Without software, most computers would be useless. For example, without your Internet  browser  software, you could not surf the Internet or read this page. Without an  operating system , the browser could not run on your computer.  The picture to the right shows a Microsoft Excel box, an example of a spreadsheet software program.
