Firewall is considered the first line of defense in protecting private 
information. For better security, data can be encrypted. A system 
designed to prevent unauthorized access to or from a private 
network. Firewalls are frequently used to prevent unauthorized 
Internet users from accessing private networks connected to the 
Internet, especially Intranets all messages entering or leaving the 
intranet pass through the firewall, which examines each message 
and blocks those that do not meet the specified security criteria.  

 

 

 

A gateway links computers that use different data formats 
together. 

 

Groups consist of several user machines that have similar 
characteristics such as being in the same department. 

 

 

 

Short for hexadecimal refers to the base-16 number system, which 
consists of 16 unique symbols: the numbers 0 to 9 and the letters 
A to F. For example, the decimal number 15 is represented as F in 
the hexadecimal numbering system. The hexadecimal system is 
useful because it can represent every byte (8 bits) as two 
consecutive hexadecimal digits. It is easier for humans to read 
hexadecimal numbers than binary numbers.

This is a private network, inside an organization or company, that 
uses the same software you will find on the public Internet.  The

only difference is that an Intranet is used for internal usage only.   

 

The Internet is a globally linked system of computers that are 
logically connected based on the Internet Protocol (IP).  The 
Internet provides different ways to access private and public 
information worldwide. 

 

To participate in Internet communications and on Internet 
Protocol-based networks, a node must have an Internet address 
that identifies it to the other nodes. All Internet addresses are IP 
addresses 

 

Internet Protocol is the standard that describes the layout of the 
basic unit of information on the Internet (the packet) and also 
details the numerical addressing format used to route the 
information. Your Internet service provider controls the IP address 
of any device it connects to the Internet. The IP addresses in your 
network must conform to IP addressing rules.  In smaller LANs, 
most people will allow the DHCP function of a router or gateway 
to assign the IP addresses on internal networks. 

 

IP address is a 32-binary digit number that identifies each sender 
or receiver of information that is sent in packets across the 
Internet.  For example 80.80.80.69 is an IP address, it is the closet 
thing the Internet has to telephone numbers. When you “call” that 
number, using any connection methods, you get connected to the 
computer that “owns” that IP address. 

 

Internet Service Provider, is a company that maintains a network 
that is linked to the Internet by way of a dedicated communication 
line.  An ISP offers the use of its dedicated communication lines 
to companies or individuals who can’t afford the high monthly 
cost for a direct connection.
