Today we learned about OS's or (operating system) using videos on you tube. We watched videos about how to partition a computers internal hard drive and how to boot windows xp from a floppy and a cd-rom. Then how to install windows 7, downloaded from the internet and then installed from a virtual drive/ image. And the we read the second chapter from the cisco academy course; Operating Systems. Chapter 2 was about many things including: The purpose of the operating system is so that all the parts in the computer can work together. It also works as a translator between user applications and system hardware. There are system requirements for a OS:
 * __Monday 28th 2011:__**
 * - Amount of RAM**
 * - Hard disk space required**
 * - Processor type and speed**
 * - Video resolution**

There are many installation methods that can be used to install a OS or to upgrade a OS such as: - **Clean Install** = A clean install is done on a new system or in cases where no upgrade path exists between the current OS and the one being installed. - **Upgrade** = It simply replaces the old OS files with the new OS files. - **Multi boot =** It is possible to install more than one OS on a computer to create a multi-boot system. Only one OS can run at a time and it has full control of the hardware.
 * - Virtualization =** Virtualization is a technique that is often deployed on servers. It enables multiple copies of an OS to be run on a single set of hardware, thus creating many virtual machines.

To configure a computer for the network, three components must exist to function: - **IP address** - identifies the computer on the network. - **Subnet mask** - is used to identify the network on which the computer is connected. - **Default gateway** - identifies the device that the computer uses to access the Internet or another network.

A computer IP address can be configured to a manual IP configuration which means; the required values are entered into the computer via the keyboard, typically by a network administrator. And through the dynamic IP configuration which means; This allows a computer to request an address from a pool of addresses assigned by another device within the network.

There are __**three ways**__ to apply OS patches to fix hardware problems related with the OS and also a patch is a piece of program code that can correct a problem or enhance the functionality of an application program or OS.
 * - Automatic Installation**
 * - Prompt for permission**
 * - Manual**



Today I read the rest of chapter 2 and completed the chapter 2 test. But however, I did poorly on that test and therefore I will be doing the test again next week to get a better mark. Chapter 2 was about operating systems and how they work within a network. All of the general material that I read within this chapter is described above, in on the Monday of march 28th 2011.

Today I started reading chapter 3 on networks and how they work with computers. The following is the genera/relevant information I read in chapter 3 on **Wednesday march 30th 2011.**

A network provides the ability to connect people and equipment no matter where they are in the world. The benefits of a network is that you can access many different types of information from around the world or from a home or business network that involves many computers and a server to store and provide information to the users. Small networks are called SOHO. Here are other uses of a network and the Internet:
 * Sharing music and video files**
 * Research and on-line learning**
 * Chatting with friends**
 * Planning vacations**
 * Purchasing gifts and supplies**

- Hosts - Hosts are devices that send and receive messages directly across the network. - Shared peripherals -Shared peripherals are not directly connected to the network, but instead are connected to hosts. The host is then responsible for sharing the peripheral across the network. - Networking devices - interconnection of hosts. - Networking media - Printer (for example)
 * Components of a network ( Some are not needed to make a functioning network):**

All computers connected to a network that participate directly in network communication are classified as hosts. Hosts can send and receive messages on the network. Servers are hosts that have software installed that enable them to provide information, like email or web pages, to other hosts on the network. Clients are computer hosts that have software installed that enable them to request and display the information obtained from the server.
 * Computer Roles in a Network:**

In small businesses and homes, many computers function as the servers and clients on the network. This type of network is called a peer-to-peer network. The simplest peer-to-peer network consists of two directly connected computers using a wired or wireless connection.
 * Peer to Peer Networks:**

Map of the physical and logical map of the network to find cables and wires and ro find all the computers that are connected to that network and all the servers ans other network bases hardware.
 * Network Topologies:**





Today is is the following general and most revelant information I read to today within chapter 3: Source, channel and destination: Message then transmiitter then transmission medium and then reciver and finally message destination.
 * __Thursday March 31st 2011:__**

Today I contined to read chapter 3 and read about switches, hubs, broadcasting messaging and the functions of all of them.
