side signals the sending side to stop until the buffer has space

 

again. Between hardware (such as your modem and your

 

computer), hardware flow control is used; between modems,

 

software flow control is used.

Hot-Swap

Ability to remove and add hardware to a computer system

 

without powering off the system.

ICMP

Internet Control Message Protocol is an Internet protocol

 

sent in response to errors in TCP/IP messages. It is an error

 

reporting protocol between a host and a gateway. ICMP uses

 

Internet Protocol (IP) datagrams (or packets), but the

 

messages are processed by the IP software and are not

 

directly apparent to the application user.

In-band Network

In a computer network, when the management data is

Management

accessed using the same network that carries the data, this is

 

called “in-band management.”

IP Address

A 32-bit address assigned to hosts using TCP/IP. It belongs to

 

one of five classes (A-E) and is expressed as 4 octets

 

separated by periods formatted as dotted decimals.

 

Each address has a network number, an optional sub network

 

number and a host number. The first two numbers are used

 

for routing, while the host number addresses an individual

 

host within the network or sub network. A subnet mask is

 

used to extract network and sub network information from

 

the IP address.

ISDN

A set of communications standards allowing a single wire or

 

optical fibre to carry voice, digital network services and

 

video. ISDN is intended to eventually replace the plain old

 

telephone system.

Kerberos

Kerberos was created by MIT as a solution to network

 

security problems. The Kerberos protocol uses strong

 

cryptography so that a client can prove its identity to a server

 

(and vice versa) across an insecure network connection.
