===Purpose of Having a Matrix AccountRedirection===
While attending Seneca College, you will be using many different computer systems to perform various operations.Some of these servers include:x

This requires that you practice issuing Linux commands on a frequent basis to become more comfortable when working the Unix and '''Linux command-line environments'''. Just like with other operating systems like MS Windows, it is important to learn how to '''open a command prompt in order to issue commands to perform common tasks'''. In Unix/Linux, a '''shell''' is simply an interface / interpreter to allow a user to communicate with the Linux computer system (server). Linux shells have evolved (improved) over a period of time. You will be using the '''Bash Shell''' which is considered to be user-friendly. By understanding how to issue Linux commands, you can create a file consisting of Linux commands and programming techniques called a '''shell script''' Grouping Commands (learned later in this course) to automate tasks to make you a more productive user and administrator. ===Layout of the Matrix Server===[[Image:matrix-layout.png|thumb|right|350px|The Matrix server consists of several Virtual Computers all connected together to form a '''cluster'''. A cluster is a '''cost effective''' alternative to larger servers. ]] The Matrix server consists of '''several Virtual Computers connected together''' to form a '''cluster'''. A cluster is a '''cost effective''' alternative to buying larger servers. All registered students in this course should have an account on the Matrix server.You will be using this account for the following reasons: :* Issuing '''Linux commands''':* Becoming productive using the Linux '''command prompt''' ('''shell'''):* Performing '''Linux Practice Tutorials''':* Performing '''Linux Assignments''' ('''3'''):* Practice Issuing '''Linux Command Review Questions'''

In the next investigation, you will learn how to '''connect''' to and '''login''' to your Matrix server account both at a '''college lab workstation''' and from a remote computer such as your '''home computer''' or your '''laptop computer'''...<br><br>
