Technology Infrastructure - Essay Example

Technology Infrastructure of the of Technology Infrastructure Media Access Card (MAC) Address: MAC address is the address referring a 32 bits unique identifier code that is burned on the Network Interface Cards (NIC) at the time of manufacturing (Fuller & Ouellet, 2002, p. 398-399). MAC Address is also terms as a hardware address or physical address. The MAC addresses for Internet Port and LAN Port are different as the router on requires two different ports for communication between local network (through LAN port) and public network (through WAN port or Internet port)Internet Protocol (IP) Address:In a TCP/IP network an IP address is a 32 bit logical identifier for the systems and networking devices.

An IP address; however, can be assigned either statically (permanent) or dynamically (temporary). In the given router scenario configuration, there are two IP addresses from two different classes i.e. 70.115.23.137 of class A (on Internet Port) and 192.168.1.1 of class C (on LAN Port). The two are different as like MAC Addresses (above). Commonly, a router owns two separate IP addresses one for the local network (LAN) and other one for accessing public network (WAN).IP Address Range:After reviewing the given scenario, the DHCP service is turned off which means that IP addresses would not assigned dynamically to the devices within the LAN structure.

Each networking device in the scenario should be assigned a unique (static) IP address within the range of given IP i.e. 192.168.1.1. As mentioned above that this is a “class C” address, and can support up-to 254 hosts. As 192.168.1.1 is configured on the router’s LAN port, broadcast address for this range is 192.168.1.255; useable range of IP addresses is 192.168.1.2- 192.168.1.254.Gateway and Subnet Mask SettingIP address of the router’s LAN port is 192.168.1.1; thus the default gateway address for every device in the LAN shall be configured as 192.168.1.1. Configured device would identify router as the “door” pointing out of the local network (LAN) towards the public network (WAN).

The subnet mask of router is configured to 255.255.255.0 which also categorized as the network segment for the given scenario, so the subnet mask of the IP address assigned to the device should also be set 255.255.255.0, as device is configured to appear in the network segment. Four Services that are Part of InternetWorld Wide Web (www):It is a system of accessing document through internet by applying standard protocols. In another words it is a transparent, easy to use, user interface for accessing internet servers regardless of knowing actual position of that server.

Domain Name Service (DNS):It is a mechanism that links the hostname with the corresponding IP address over web (Blank, 2004, p. 174-175). In other words in is a translation of human readable names into machine readable IP addresses. Every URL has a corresponding IP address in the DNS database. Whenever a website is accessed from a system it is automatically resolved in DNS database and points the query towards a static IP hosting that website. File Transfer Protocol (FTP):Transferring of file to the remote location can be achieved by FTP, an internet stand for this purpose (Behrens, 2005, p. 187-188). It is simplest and secure method for transferring of files over the World Wide Web.

Actions like edit, renaming, moving of file from one location to another can also be performed using FTP.Telecommunication Network (Telnet):It is standard protocol that helps in making connection with the remote host using internet. It enables the user to manage the connected device remotely. The most important thing about telnet is that it is an unsecure protocol which sends data in a clear text form that can be easily sniffed.ReferencesFuller, R., & Ouellet, E. (2002).
