EXPERIMENT-1.a Aim: Study of following Network Types. • PAN • LAN • MAN • WAN Apparatus (Software): No software or hardware needed. Procedure: Following should be studied to understand this practical. Types of Networks There are several different types of computer networks. Computer networks can be characterized by their size as well as their purpose. The size of a network can be expressed by the geographic area they occupy and the number of computers that are part of the network. Networks can cover anything from a handful of devices within a single room to millions of devices spread across the entire globe. Some of the different networks based on size are: Personal area network, or PAN Local area network, or LAN Metropolitan area network, or MAN Wide area network, or WAN In terms of purpose, many networks can be considered general purpose, which means they are used for everything from sending files to a prin...

IPv4 Classes and Subnetting

Image
Aim: Write a program to find out class of a given IP address, subnet mask & first & last IP address of that block. Apparatus (Software): Eclipse/ Netbeans Procedure: Following should be studied to understand this practical. IPv4 Addressing and Subnetting Hardware Addressing A hardware address is used to uniquely identify a host within a local network. Hardware addressing is a function of the Data-Link layer of the OSI model (Layer-2). Ethernet utilizes the 48-bit MAC address as its hardware address. MAC address is most often represented in hexadecimal, using one of two accepted formats: 00:43:AB:F2:32:13 The first six hexadecimal digits of a MAC address identify the manufacturer of the physical network interface. This is referred to as the OUI (Organizational Unique Identifier). The last six digits uniquely identify the host itself, and are referred to as the host ID. The MAC address has one shortcoming – it contains no hie...
