NETWORK ADDRESS It is more commonly known as IP address. It is the numeric address of a computer connected to the network. Is a set of numbers, called ass "octets" or "dotted decimal" notation, that identifies any network device. Example: 172 . 16. 254. 1 IP Version 1. IPv4 - IP version 4 is the standard version. 2. IPv6 - IP version 6 is the advance version. IPv4 - Internet Protocol version 4 IPv4 address are canonically represented in dotted-decimal notation, which consists of four decimal numbers, each ranging from 0 to 255, separated by dots, eg., 172.16.254.1. Each part represents a group of 8 bits (octets) of the address. Binary Digit of 172 128     64     32     16     8     4     2     1    1        0        1       0      1      1...

TYPES OF CABLE  CABLE It is a medium that connects computer in a network. A. Twisted Pair Cable It is the most common type of cable. Have eight individual copper wires bundled together and covered with an insulating material. The copper is always color-coded with a plastic insulators and they are twisted in pairs for a total of four pairs.       a. STP (Shielded Twisted Pair)           often used in "noisy" environments where a shielded of metallic foil is wrapped around each of the wire pairs, with an additional overall shielding to protect against excessive electromagnetic interference.       b. UTP (Unshielded Twisted Pair)           is the most common form of twisted pair wiring.           it is less expensive and easier to work with then STP. B. Coaxial Cable The standard media used by cable TV operators. It consists of a plastic insu...

TYPES OF NETWORK TOPOLOGY NETWORK TOPOLOGY Network Topology is the schematic description of a network arrangement, connecting various nodes (sender and receiver) through lines of connection. BUS TOPOLOGY Bus topology is a network type in which every computer and network device is connected to single cable. When it has exactly two endpoints, then it is called Linear Bus topology . RING TOPOLOGY It is called ring topology because it forms a ring as each computer is connected to another computer, with the last one connected to the first. Exactly two neighbors for each device. STAR TOPOLOGY In this type of topology all the computers are connected to a single hub through a cable. This hub is the central node and all others nodes are connected to the central node. MESH TOPOLOGY It is a point-to-point connection to other nodes or devices. All the network nodes are connected to each other. HYBRID TOPOLOGY It is two different types of topologies...

TYPES OF NETWORK NETWORK A computer network, or data network, is digital telecommunications network which allows nodes to share resources. In computer networks, computing devices exchange data with each other using connections (data links) between nodes. These data links are established over cable media such as wires or optic cables, or wireless media such as WiFi. source: Wikipedia PERSONAL AREA NETWORK (PAN) A personal area network (PAN) is a computer network organized around an individual person, and that's set up for personal use only. They typically involve a computer, phone, printer, tablet and/or some other personal device like a PDA. source: Lifewire LOCAL AREA NETWORK (LAN) A local area network (LAN) supplies networking capability to a group of computers in close proximity to each other, like in an office building, school, or home. LANs are usually built to enable the sharing of resources and services like files, printers, games, applications, emai...
