An Internet Protocol address (IP address) is a numerical label assigned to each device participating in a computer network that uses the internet protocol for communication. An IP address serves two principal functions: host or network interface identification and location addressing. The designers of the Internet Protocol defined an IP address as a 32-bit number 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 the address, a new version of IP, IPv6 using 128 bits for the address, was developed in

The frame is then examined by each successive device, and if the frame address matches a given device, it takes a copy of the data and sets the token to 0. The frame is then sent back around the ring to the sending device as an acknowledgment, which then clears the frame. ii. Bus Topology uses a common backbone to connect all devices. A single cable which is the backbone functions as a shared communication medium that devices attach or tap into with an interface connector. Bus topology iii. Star or Mesh Topology is one of the most common network setups where each of the devices and computers on a network connect to a central hub. A major disadvantage of this network topology is that if the central hub fails, all computers connected to that hub would lose connectivity. Star topology Wide Area Network (WAN), spans a large geographical area, often a country or continent. WANs utilize public communication links. The largest and most well-known example of a WAN is the Internet. WANs often connect multiple smaller networks such as LANs or MANs. A WAN can have a distance of 100 to 10,000 km around a continent, transmission rates are typically 2 Mbps, 34 Mbps or more. WAN network topology Fiber Optic Technology Fiber optic cable uses optical fibers that carry digital signal in form of modulated pulses of light. It consists of an extremely thin cylinder of glass called the core surrounded by a concentric layer of glass called the ‘cladding’. There are two fibers in each cable, one for transmitting and the other for receiving data. To reduce signal loss, the core can also be an optical-quality clear plastic, and the cladding can be made up of gel that reflects signals back into the fiber. Fiber-optic cables have signal strength over long distances and are highly secure from outside interference and electrical noise. However, they are too expensive. There are two types of fiber-optic cables: Single-mode fiber (SMF) Multi-mode fiber (MMF) Single-mode uses a single ray of light known as mode to carry transmission over long distances of about 2km, while Multi-mode uses multiple ray of light simultaneously to carry transmission over short distances. Hub and Switch and Router ROUTERS: A router is a networking device that forwards data packets between computer networks. Routers perform traffic directing functions on the internet. A data packet is typically forwarded from one router to another through the networks that constitute the internet until it reaches the destination node. SWITCHES: In networks, a device that filters and forwards packets between LAN segments is termed switch. LANs that use switch to join segments are called switched LANs. HUBS: A common connection point for devices in a network is termed a Hub. Hubs are commonly used to connect segments of a LAN. A Hub contains multiple ports and it floods the host system. It doesn’t filter messages rather it floods the different host on the network with the message and the one who owns the message regards it while the others disregard it. A HUB AND A SWITCH Network interface Card (NIC) A NIC (pronounced 'nick') is also known as a network card. It connects the computer to the cabling, which in turn links all of the computers on the network together. Each computer on a network must have a network card. Most modern network cards are 10/100 NICs and can operate at either 10Mbps or 100Mbps. Only NICs supporting a minimum of 100 Mbps should be used in new installations students. Computers with a wireless connection to a network also use a network card. NIC CARD OPEN SYSTEM INTERCONNECTION LAYER (OSI LAYERS) The OSI model defines internetworking in terms of a vertical stack of seven layers. The upper 3 layers of the OSI model represent software that implements network services like encryption and connection management. The lower 4 layers of the OSI model implement more primitive, hardware-oriented functions like routing, addressing, and flow control. Internet protocol address The Internet Protocol (IP) is the method or protocol by which data is sent from one computer to another on the Internet. Each computer (known as a host) on the Internet has at least one IP address that uniquely identifies it from all other computers on the Internet. 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. An IP address serves two principal functions: host or network interface identification and location addressing. The designers of the Internet Protocol defined an IP address as a 32-bit number 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 the address, a new version of IP, IPv6 using 128 bits for the address, was developed in
