A collection of computers and devices connected by communications channels that facilitates communication among users.
Internet Service Provider (ISP)
Internet access providers connect users to the Internet and are commonly referred to as ISPs, or Internet service providers. They are organized as local, regional, and national providers. Local providers connect to regional providers. Local providers may only work in a limited number of cities or even perhaps one city.
A small hardware device that connects computers together within one LAN. Uses MAC addressing. Forwards traffic within a network.
All Internet communication utilizes IP addressing. The IP address tells you the exact address of a host. The subnet mask reveals the network in which the host resides through use of a process called ANDing. ANDing involves binary mathematics and is beyond the scope of this unit.
Net work IP Addressing
192.168.10.1 thru 192.168.10.254 are all part of the same network. (numbers 0-255 are used) 10.0 and 10.255 are reserved for routing.
Dynamic IP Address
On the Internet, all devices possess and are assigned public IP addresses. ISPs generally provide you with a public IP address that may change from day to day. This is known as a dynamic IP address.
Private IP Address
An IP address is generally defined as public or private. Private IP addresses have no 'real world' meaning and are indeed invalid outside of their network, Your cable modem router has both a public and a private IP address. A private IP address is used to communicate with your home computers and printer. All of these devices are configured with private IP addresses. Private IP addressing is used on home networks and office intranets. The public IP address, on the other hand, is used to communicate with devices that are on the Internet.
Public IP Address
The public IP address is used to communicate with devices that are on the Internet.
Media Access Control address, is stamped, usually on a sticker, on each installed NIC of a device. The MAC address on your NIC has no meaning outside of the network in which you are currently connected.
Institute of Electrical and Electronic Engineers
Creates and publishes networking and other standards. Standardization enables products from various vendors to work together.
Maps an IP address to what is referred to as a domain name. DNS, which is a method that allows people to use names in conjunction with IP addressing. A domain name is an identification label, that defines a realm of administrative autonomy, authority, or control of the Internet based on the domain name system or DNS.
Is a computer with special operating system software installed and is able to create and manage a domain.
3 Factor Authentication
Password includes, something it knows, something it has, and something it is.
Intrusion Protection Systems
An IPS is similar to a firewall but provides much more protection. The IPS monitors all network traffic, in real time, for malicious activity.
A collection of people, processes and technology that generates and uses information in an organization.
