Fragmentation  – 

Breaking a packet into smaller units when transmitting 

over a network medium that cannot support the

 

original size of the packet. 

 

Hardware  – 

Hardware is the physical aspect of computers, 

telecommunications, and other information technology devices.  The term 

arose as a way to distinguish the “box” and the electronic circuitry and 

components of a computer from the program you put in it to make it do things.  

The program came to be known as the software.

 

 

Hub – 

The device that serves as the central location for attaching wires from 

workstations.  Can be passive, where there is no amplification of the signals; 

or active, where the hubs are used like repeaters to provide an extension of 

the cable that connects to a workstation.

 

 

IEEE  – 

The Institute of Electrical and Electronics Engineers.  The  IEEE 

fosters the development of standards that often become national and 

international standards.  The organization publishes a number of journals, 

has many local chapters, and has several large societies in special areas, 

such as the IEEE Computer Society.

 

 

IEEE 802.11 – 

Industry standard that enables wireless LAN hardware from 

different manufacturers to communicate.

 

 

Infrastructure Mode  – 

Allows all computers on a wired and wireless 

network to share a peripheral, such as a printer or

 

high speed Internet

 

Access.

IP Address – 

In the most widely installed level of the Internet Protocol (IP) 

today, and IP address is a 32-binary digit number that identifies each sender 

or receiver of information that is sent in packets across the Internet.  When 

you request an HTML page or send e-mail, the Internet Protocol part of 

TCP/IP includes your IP address in the message (actually, in each of the 

packets if more than one is required) and sends it to the IP address that is 

obtained by looking up the domain name in the Uniform Resource Locator you 

requested or in the e-mail address you’re sending a note to.  At the other end, 

the recipient can see the IP address of the Web page requestor or the e-mail 

sender and can respond by sending another message using the IP address it 

received. 

 

IPCONFIG – 

A utility that provides for querying, defining and managing IP 

addresses within a network.  This utility is commonly used under Windows 

NT and 2000, for configuring networks with a static IP address. 

 

IPSec  – 

IPSec (Internet  Protocol  Security) is a developing standard for 

security at the network or packet-processing layer of network communication.  

A big advantage of IPSec is that security arrangements can be handled 

without requiring changes to individual user computers.

 

 

IRQ 

(Interrupt ReQuest) – A hardware interrupt on a PC.  There are 16 IRQ 

lines used to signal the CPU that a peripheral event has started or terminated.  

Except for PCI devices, two devices cannot use the same line.
