| UML | |
| Unified Modeling Language (UML) is a standardized specification language for object modeling. UML is a general-purpose modeling language that includes a graphical notation used to create an abstract model of a system, referred to as a UML model. |  |
| UML is officially defined at the Object Management Group (OMG) by the UML metamodel, a Meta-Object Facility metamodel (MOF). Like other MOF-based specifications, the UML metamodel and UML models may be serialized in XMI. UML was designed to specify, visualize, construct, and document software-intensive systems. | |
| UML is not restricted to modeling software. UML is also used for business process modeling, systems engineering modeling, and representing organizational structures. The Systems Modeling Language (SysML) is a Domain-Specific Modeling language for systems engineering that is defined as aUML 2.0 profile. | |

| TCP/IP | |
| TCP/IP is a communications protocol used to transfer digital data around the internet. |  |
| TCP and IP were developed by a Department of Defense (DOD) research project to connect different networks designed by different vendors into a network of networks (the "Internet").TCP/IP is often referred to as the 'internet protocol'. | |
| TCP/IP stands for Transmission Control Protocol/Internet Protocol. If this leads you to think that it is not just one protocol, you’re right. In fact, it is not just two protocols, either. TCP/IP is a suite of protocols. | |
| IP is the bedrock protocol of TCP/ IP. Every message and every piece of data sent over any TCP/ IP network is sent as an IP packet. | |
| IP’s job is to enable data to be transmitted across and between networks. Hence the name: inter- net protocol. | |

| Inside BIOS | |
| Basic Input/Output System also incorrectly known as Basic Integrated Operating System and occasionally Built In Operating System. |  |
| BIOS refers to the firmware code run by an IBM compatible PC when first powered on. | |
| The primary function of the BIOS is to prepare the machine so other software programs stored on various media (such as hard drives, floppies, and CDs) can load, execute, and assume control of the PC. | |
| This process is known as booting up. | |
| BIOS The set of routines stored in read-only memory that enable a computer to start the operating system and to communicate with the various devices in the system, such as disk drives, keyboard, monitor, printer, and communications ports. | |
| Inside Operating System | |
| An Operating System is the software that controls the operation of a computer, directs the input and output of data, keeps track of files, and controls the processing of computer programs. |  |
| Its roles include managing the functioning of the computerhardware, running the applications programs, serving as an interface between the computer and the user, and allocating computer resources to various functions. Through a process called time-sharing, a large computer can handle interaction with hundreds of users simultaneously, giving each the perception of being the sole user. | |
| When several jobs reside in the computer simultaneously and share resources (multitasking), the OS allocates fixed amounts of CPU time and memory in turn or allows one job to read data while another writes to a printer and still another performs computations. | |
| Operating systems offer a number of services to application programs and users. Applications access these services through application programming interfaces (APIs) or system calls. By invoking these interfaces, the application can request a service from the operating system, pass parameters, and receive the results of the operation. | |
| For hand-held and desktop computers, the GUI is generally considered part of the operating system. For large multiuser systems, the GUI is generally implemented as an application program that runs outside the operating system. | |
| Working With PHP | |
| This Manual is for developing a web application starting fromScratch , we here discuss every thing from the Beginning and giving you a step by step knowledge , expecting you don’t know about the web development, how can you start web development, what is the requirements & tools, what is theeditors to be used etc.In spite of these we here give a step by step help section, print screens, Interview Questionsand appendix to actually visualize you to grasp the Logic as well as presentation of actual web development. |  |
| This manual, teaches you all flavors of development phases starting from Learning the concept, explaining with examples, basic requirement for a software development, tools software’s, leaning materials and giving the idea of how a software development process going on with providing DFD, flowchart E-R diagram, and suitable screen shots and of course project documentation. | |
| And as soon as you follow this, at the last you must feel that the fear of the evil of development will go, and now you have capability to develop software. | |
