Starting Point Chapter 15:
Local Area Network is well connected. It is created to share related Resources. Some examples of "Nodes" are : computer, router, printer, sensing device, video camera, and controller. This can connect to External Networks. It has a central server that everyone is communicating with. It is local. You log onto a security base. 2 major catagories pere to pere, (# of computers lives on each of computers). They have been around awhile. Another is Client server network. With Peer-to-peer each user has to have a valid user ID and password. It is approved by the client operating system. The local user acount exists only on a single computer. One user may have many accounts on differnt server. Security principle is somthing that gains control. Without user accounts there are no problems. Accessing Shares- My network places, map network drive, internet explorer, run menue. Client/ Server Model- Server mangages security for LAN. for example User accounts, printers, and file sharing. There is Single network user ID and password. Authenticate against the NOS too. It's the domain model and the Adminstrator assigns permissions. The server stores info in the database as well. One chooses the user name, password and the network you wish to work on. The authentication is done on the server. domain means everyone is logging onto teh same server. In order for a client to participate they have to have a network client. The machine needs a domain. One has to tell it which network to join. One has to install a protocall in a network card. The point of the protocall is to connect to novel servers. Net booy is unroutable. Can't get on internet. TCPIP is what most people use. UTP and STP has Ethernet nework. UTP-Unsheieded twsited pair. STP-Shielded twisted pair.

1.5 starting point chp 14.
Getting Windows Version one goes to Command Line: VER.Or one can go to start and then run and type in Winver. Task Manager shows what software is running on the machine. Or what is taking up the most amount of memory. Control, alt, delete takes one there automatically. Or one can right click on the task bar. The 1st it does is show all the running applications. When running windows, alot of prperties are already running. If we don't see columns your looking for, look at the different processes. The performance tab shows page file usage and CPU usage. If the machine is running slow it means we're experienceing some type of overload. If the machine has users that are able to be logged on at the same time thn one uses the ussers tab. It is informative because we can know what they're doing. Services is a control pannel outlet. It allows necessary services and running unneeded services. It consumes resources and adds overhead. It adds a security risk. In windows there is a group called "start-up". It happens when you reboot your computer. Norton Anto-Virus sometimes runs automatically. If one wants info on their Microsoft
Installed Software its in your Help and Support center. error reporting is microsofts way of knowing the memory address and come up with a way of fixing it. Even Viewer is the best place to go for any amount of trouble shooting. Info of the error or if it effected a user or not. It gives warning. Mrs.Happy then told us a story... my selective hearing then kicked in ;).
Under Event Viewer is categories and event info along with event types and Remote Adm can connect to teh PC via network. Once the log file is being overwrite u can manually clear a log or make a different choice. Event Viewer is a good trouble shooter. In most machines there are usually 3 logs in event viewer. The warning is a huge message. The registry all stystems info. Hacking is getting in there and making something else different. The registry has Keys. It is devided into sections. Values are types of data. Exporting th Resistry you 1st Open Regedit. Choose file, export, save the file with a suitable name in a secure location.
