Protecting your Computer

Protecting your Computer

3 ways in which you can protect you computer



DATA Security

This protects the data on the network, ways in which you can don this is, antivirus, spyware or firewalls. I also suggest backing up and valuable information and adding a spam filter.

Access Security

This controls who is able to access the information through out the network, ways in which you can do this is, having multiple passwords and also by setting the networks access rights.

Physical Security

This mean to take actually action in the real world to protect you network, ways in which you can do this is, having locks on server rooms. Also having surveillance in and around the room and having quality locks on the door or any other access points. Also I recommend having backups of the data.

LAN and WAN

What Is LAN and 

 WAN

 

LAN stands for Local Area Network
WAN stands for Wide Area Network

Examples of where you may find a 

LAN; schools, home and shops
WAN; chain of shops

WANs connects multiple LANs and other network types together. It its mostly used to link things together so that users and computers in one location can connet with other users in other locations. Most WANs are built by organisations and are usually private and has limited access.

3 Types of Servers

The 3 types of servers

There are 3 main computer servers; file servers, printer servers and email servers.

File servers: this is a server dedicated to storing files and documents, any user on the network can store files on the server. 

Network server: this is a server that manages network traffic on a single device.

Print Server: this is a server that connects printers to peoples computers over a network, it accepts print jobs from the computers and sends them to the appropriate printers.

The difference between The Internet and WWW

Many People wonder if and what the difference

Is between the internet and WWW

(world wide web) 

 

People commonly use the internet meaning web and vice versa. However this is a actually wrong, as the internet is the container of the information and the web is only how you access that information.

The internet; Is a massive network that connects everything together it is the infrastructure for the web.

The WWW; Is the space where all the information and document are stored, they are identified by URIs, interlinked by hypertext links to get to the correct page.

The massive difference is that with out the internet you would not have the web as the internet lets everyone (that is connected to WIFI) to access the information from the web.
