An Internet Protocol address (IP address) is a numerical label assigned to each device (e.g., computer, printer) participating in a computer network that uses the Internet Protocol for communication. [1] An IP address serves two principal functions: host or network interface identification and location addressing . Its role has been characterized as follows: "A name indicates what we seek. An address indicates where it is. A route indicates how to get there." [2] The designers of the Internet Protocol defined an IP address as a 32-bit number [1] and this system, known as Internet Protocol Version 4 (IPv4), is still in use today. However, because of the growth of the Internet and the predicted depletion of available addresses , a new version of IP ( IPv6 ), using 128 bits for the address, was developed in 1995. [3] IPv6 was standardized as RFC 2460 in 1998, [4] and its deployment has been ongoing since the mid-2000s. IP addresses are usually written and displ...

What is application software? A program or group of programs designed for end users. Application software can be divided into two general classes: systems software and applications software. Systems software consists of low-level programs that interact with the computer at a very basic level. This includes operating systems compilers , and utilities for managing computer resources. In contrast, applications software (also called end-user programs) includes database programs, word processors, and spreadsheets. Figuratively speaking, applications software sits on top of systems software because it is unable to run without the operating system and system utilities. There are a lot of terms can be found over the internet related to computer. All type of computer have processor, Memory, keyboard, mouse and screen to display output. But their is a significant differenc...

Memory is the best essential element of a computer because computer can’t perform simple tasks. The performance of computer mainly based on memory and CPU. Memory is internal storage media of computer that has several names such as majorly categorized into two types, Main memory and Secondary memory. 1. Primary Memory / Volatile Memory. 2. Secondary Memory / Non Volatile Memory. 1. Primary Memory / Volatile Memory: Primary Memory also called as volatile memory because the memory can’t store the data permanently. Primary memory select any part of memory when user want to save the data in memory but that may not be store permanently on that location. It also has another name i.e. RAM. Random Access Memory (RAM): The primary storage is referred to as random access memory (RAM) due to the random selection of memory locations. It performs both read and write operations on memory. If power failures happened in systems during memory access then you will lose your dat...

Why files are needed? When a program is terminated, the entire data is lost. Storing in a file will preserve your data even if the program terminates. If you have to enter a large number of data, it will take a lot of time to enter them all. However, if you have a file containing all the data, you can easily access the contents of the file using few commands in C. You can easily move your data from one computer to another without any changes. Types of Files When dealing with files, there are two types of files you should know about: Text files Binary files 1. Text files Text files are the normal .txt files that you can easily create using Notepad or any simple text editors. When you open those files, you'll see all the contents within the file as plain text. You can easily edit or delete the contents. They take minimum effort to maintain, are easily readable, and provide least security and takes bigger storage space. 2. Binary files...

call by value call by reference In call by value , a copy of actual arguments is passed to formal arguments of the called function and any change made to the formal arguments in the called function have no effect on the values of actual arguments in the calling function. In call by reference , the location (address) of actual arguments is passed to formal arguments of the called function. This means by accessing the addresses of actual arguments we can alter them within from the called function. In call by value, actual arguments will remain safe, they cannot be modified accidentally. Example using Call by Value The classic example of wanting to modify the caller's memory is a swapByValue() function which exchanges two values. For C uses call by value, the following version of swap swapByValue() will not work... #include <stdio.h>   void swapByValue ( int , int ) ; /* Prototy...

First of all: not all books are the same. The best advice is to contact with your printing service before to start, in order to know the size of the page, the amount of pages, margins, colors and more. ie if you make a full-color book is more expensive than a book with only black pages.  When you start, create a new document, setup the page (double click on the page border) and choose twice the real size. ie if the book is 14x20cm , choose 28x20 cm Then, go to "Layout" and choose "Booklet" and "facing pages". That's all. The first page will be alone, same for the last one, and the other page will be in the same order that you will read the book (2-3. 4-5) etc.  Before to place the content, choose margins, columns and Text styles (Ctrl+F5) for a fst and secure edition. The rest of the job will be easy and simple For print the book, you can use the imposition features in the Print preview, but the best solution is to go to FI...

Computer viruses are small software programs that are designed to spread from one computer to another and to interfere with computer operation. A virus might corrupt or delete data on your computer, use your e-mail program to spread itself to other computers, or even erase everything on your hard disk. Computer viruses are often spread by attachments in e-mail messages or instant messaging messages. That is why it is essential that you never open e-mail attachments unless you know who it's from and you are expecting it How Computer Viruses Work? Here is the general way that viruses work: An infected program is run. This is either a program file (in the case of a file-infecting virus) or a boot sector program at boot time . In the case of a Microsoft Word document the virus can be activated as soon as the document that contains it is opened for reading within Microsoft Word. If the "NORMAL.DOT" document template is inf...

A network switch is a small hardware device that centralizes communications among multiple connected devices within one local area network (LAN) . Standalone  Ethernet switch devices were commonly used on home networks many years ago before home  broadband routers became popular. Modern home routers integrate Ethernet switches directly into the unit as one of their core functions. High-performance network switches are still widely used in corporate networks and data centers. Network Switch Technology While switching capabilities exist for several kinds of networks including ATM and Token Ring , Ethernet switches are the most common type. Mainstream Ethernet switches like those inside broadband routers support Gigabit Ethernet (1 Gbps ) speeds per individual link (switch port), but high-performance switches like those in data centers generally support 10 Gbps per link. Different models of network switches support varying numbers of connected devices...

www.google.com A router [a] is a networking device that forwards data packets between computer networks . Routers perform the traffic directing functions on the Internet . A data packet is typically forwarded from one router to another through the networks that constitute the internetwork until it reaches its destination node. [2] A router is connected to two or more data lines from different networks. [b] When a data packet comes in on one of the lines, the router reads the address information in the packet to determine the ultimate destination. Then, using information in its routing table or routing policy , it directs the packet to the next network on its journey. This creates an overlay internetwork. The most familiar type of routers are home and small office routers that simply pass IP packets between the home computers and the Internet. An example of a router would be the owner's cable or DSL router, which connects to the Internet through an Internet serv...
