IP Addresses And Subnet Masks

Addressing for intranets (and the Internet) explained TCP/IP is the networking protocol of the Internet, and by extension of intranets. For TCP/IP to work, your network interfaces need to be assigned IP addresses. Note that we said network interfaces and not computers. The IP addresses are assigned to interfaces and not to computers. So, one computer can have more than one IP address. For example, if you have two network cards on your computer, then each of them can have a different IP address either static or dynamic (more about that in a minute). Similarly, if you have a proxy server running, then the machine on which it is installed should have a static IP address. Now, the same machine has to establish a dial-up link to the Internet through, say VSNL. Then the dial-up adapter would be assigned a different dynamic address. What's an IP address? An IP address is a number that represents a device like a network card uniquely on the Internet or on your company's int...

Computer Memory

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...

IP address

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...
