Instructor: Ellis Hodgdon
Introduction: First off to start the assignment only requires writing about four different types of failures that can happen on a distributed system, however there are many more than just four types of failures that can happen and they are all important to learn about if you are going to work with a distributed system so that you know how to deal with and handle each one of them. Failures are important to know about that way if they do happen you know the steps to take to resolve and fix them in a timely manner. The more you know about failures, the less likely they are to cause severe problems to your computer or network. It is also important to know that failures can happen on both a centralized system and a distributed system.
Definition of a Centralized System: A centralized system is a computer that is by itself. An example of a centralized system would be a home computer that is not part of a network. These days many homes have multiple computers that are connected to a home network which is a distributed system. However I myself have only 1 computer in my house and this is a centralized system as it isn’t connected to a network.
Definition of a Distributed System: A distributed system is basically two or more computers that have their own processors and memory that are linked together through a network such as a WAN or LAN. These computers can communicate with each other through the network and are able to share resources such as the ability to use the same printer to print documents. The computers in a distributed system can also communicate with each other and share files and do quite a bit of other things as well.
Definition of Failures: A failure happens when a piece of equipment such as the hardware or software on a computer aren’t working properly. When the computer isn’t working properly, it can cause problems such as data loss, reduced
