Traveling Through a Network

-


    A computer communicates via the Internet by dividing data into chunks which are called packets and contains information such as an address for a destination computer, the data size, and the data itself. Packets have a maximum of 30 hops to a local Internet Service Provider (ISP).  

    The three sites that I decided to use were google.com, yahoo.co.jp, and abc.net.au and out of all three websites, google.com was the fastest with traveling through the network. The ping and traceroute results for abc.net.au shows that the host is unreachable across an IP network as the packets that were sent were lost during the ping activity and as for the traceroute it reached its maximum 30 hops providing no results as it kept timing out. Also, I have noticed that for yahoo.co.jp it was unreachable around hop 4 and 5 but it then started traveling through the network just fine. It did take a little longer than google.com for the other websites.  

The ping command could be used to troubleshoot Internet connection problems by testing whether the network is reachable. Ping commands could be used to determine whether a certain host is “alive” or not. Traceroute command could be used to troubleshoot Internet connections problems by tracing the path between the sender and the destination host. A ping request or traceroute command might time out or return with an error response because when ping is blocked then the server does not respond at all. This results in “Request timed out” messages in the command prompt. With these messages, it prevents the traceroute from being able to map the path to the final destination.

       The use of computers is essential in the insurance industry.  The  main purpose of insurance is to protect our assets and  in the event  of a loss, we report a claim. Insurance companies must have a database that includes auto claims,  home claims, catastrophe claims and more.  Technology is used in insurance to assist policyholders with filing a claim and for adjusters to handle them as well  quickly and efficiently .        The functions of computers in the insurance industry are to store data or information and processing data/information.  The   employees that are handling claims have their own personal computer. They are required to keep their computers locked when they are away from their desk as there are customer’s personal information stored in a claims database that associates have access too. In order for the data to be processed or stored, the employees will input the data using their...

     The type of attack that can be executed using pings commands is commonly known as the ping of death. The ping of death is a form of denial-of-service attack, and this is when attackers crashes or freezes a computer by sending a ping larger than the Internet Protocol packet which is formed of 65,535 bytes. Most legacy computers cannot handle larger packets. When attackers violates the IP rule, it overwhelms the computers memory and causes it to crash, destabilize, or freeze. In order for organizations to avoid this type of attack, they will need to avoid using legacy equipment's and constantly update their software as they are the most vulnerable.  Computers systems are vulnerable to phishing threats because hackers gain access to sensitive data such as passwords or credit card details. Hackers achieve this by pretending to be someone else like a well-known company or authoritative figure via email, text message, or telephone and manipulate user's into giving up ...

What is Database Management? "Information technology (IT) is the  use of any computers, storage, networking and other physical devices, infrastructure and processes to create, process, store, secure and exchange all forms of electronic data   (Castagna & Bigelow, 2021) ".      Data has become an asset for organizations and it is important for the data that is being stored remain private, secure, and organized - especially when an organization is dealing with very large data. Data is collected using modern software applications and databases are a common way to store and manage data using such applications. Organizations uses database applications to  create and administer databases. Database Management Systems (DBMS) are desktop applications that users use for business purpose. The purpose of database management systems is to store and transform data into information to support businesses decision making.  Database management systems are in re...
