HOW TO SHARE FILE AND PRINTER IN A COMPUTER NETWORK?

- March 06, 2019

How to Share File and Printer in a Computer Network? IP Address or Internet Protocol address is a numerical label assigned to each device connected to 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. There are four preliminary steps to share a file and printer in a computer network : 1. Create an IP address 2. Configure the IP address 3. Set Windows firewall settings 4. Set up a home or small office network For the past lessons we have already been discussed about creating and configuring IP address. Set Windows firewall settings Turn off firewall Firewall - is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. Set up a home or small office network Network Setup Wizard Network Setup Wizard - is a built

WHAT IS A NETWORK OR IP ADDRESS?

- January 16, 2019

NETWORK ADDRESS It is more commonly known as IP address. It is the numeric address of a computer connected to the network. Is an asset of numbers called as 'octets' or 'dotted decimal' notation that identifies any network device. most common IP address: 192.168.1.1 IP VERSIONS IPv4 or IPversion4 - is the standard version IPv6 or IPversion6 - is the advanced version Internet Protocol Version 4 (IPv4) I Pv4 addresses are canonically represented in dotted notation, which consists of four decimal numbers, each ranging from 0 to 255, separated by dots. Each pair represents a group of 8 bits (octet) of the address. picture is from: https://www.comms-express.com/infozone/article/ipv4/ Classes of IP Address Class A - 1 to 126 Class B - 128 to 191 Class C - 191 to 223 Class D - 224 to 239 Class E - 240 to 255 Note: function value: 127 for mu

TYPES OF CABLE

HERE ARE THE TYPES OF CABLE: 1. Twisted Pair Cable a .STP-Shielded Twisted Pair b. UTP-Unshielded Twisted Pair 2. Coaxial Cable 3. Fiber-optic Cable 1. Twisted-Pair-Cable It is the most common type of cable and have eight individual copper wires bundled together and covered with an insulating material. a. Shielded Twisted Pair (STP) picture source: https://5.imimg.com/data5/BS/UQ/MY-35673791/shielded-twisted-pair-cable-500x500.jpg Often used in 'noisy' environments where a shield of metallic foil is wrapped around each of the wire pairs, with an additional overall shielding to protect against excessive electromagnetic interference. b. Unshielded Twisted Pair (UTP) picture source: https://s3-us-west-1.amazonaws.com/foscoshopify/graphics/uploads/2011/01/UTP-Cable-Picture.jpg - Is the most common type form of twisted pair wiring and less expen

WHAT ARE THE TYPES OF NETWORK TOPOLOGY?

- September 01, 2018

LINEAR BUS TOPOLOGY Linear bus topology is a type of network topology which each device is connected one after the other in a sequential chain (shown right). In this case, the bus is the network connection between the devices, and if any link in the network chain is severed, all network transmission is halted. It works well for small networks because it is simple to set up and utilizes shorter cables since each device is connected to the next. It is a poor solution for larger networks, however since the entire network relies on each connection, and network speed is reduced as more devices are added. source: https://www.computerhope.com/jargon/l/linear-bus-topology.htm STAR TOPOLOGY Alternatively referred to as a star network , star topology is one of the most common network setups. In this configuration, every node connects to a central network device, like a hub, switch, or computer. The central network device acts as a server and the peripheral device
