100
This works with firewalls to allow only authorized access to corporate systems and information. They are also known as a list of rules that defines who can access operational systems.
What are ACL’s (Access Control Lists)?
100
A standard from Motorola, Ericsson and Nokia for providing cellular phones, pagers and other such handheld devices with secure access to e-mail and text-based Web pages.
What is WAP (Wireless Application Protocol)?
100
Enables IP traffic to travel securely over a public TCP/IP network by encrypting all traffic from one network to another.
What is VPN (Virtual Private Network)?
100
Connection point between the server and the workstation in a LAN. In an Ethernet network, a device to which all clients and servers are wired.
What is a hub?
100
Contains the information in a Data Packet
What is a Data Area?
200
The software and/or hardware used to block certain kinds of traffic to corporate information systems from the Internet and corporate online systems. Used to keep out hackers and any unauthorized access.
What is a Firewall?
200
A version of HDML, and WMLScript, a compact JavaScript-like language that runs in limited memory.
What is Wireless Markup Language (WML)?
200
A high-speed packet switching protocol used in wide area networks where packets are known as frames.
What is Frame Relay?
200
A protocol introduced by Xerox Corp. in 1975. It was developed as an inexpensive way of sending information quickly between office machines connected together in a single room or building, but it rapidly became a standard computer interconnection method.
What is Ethernet?
200
The speed at which data is transmitted in a Packet Switched Network.
What is Bit Rate?
300
A dedicated computer or device running security software
What is firewall appliance?
300
A consortium of computer and telecommunications companies founded in 1998 by Ericsson, IBM, Intel, Nokia and Toshiba. It supports an open specification for wireless, short-range transmission between mobile PCs, mobile phones and other portable devices.
What is Bluetooth?
300
A cell relay, packet-switching network protocol which encodes data traffic into small fixed-sized cells (53 bytes).
What is ATM (Asynchronous Transfer Mode) ?
300
A network of circuits that directly connect two, and only two locations. WANs are often created by this method.
What is Point-to-Point?
300
That which slows down the speed of data transmission in a Packet Switched Network.
What is latency?
400
It is widely used to do two things: to validate the identity of a Web site and to create an encrypted connection for sending credit card and other personal data.
What is SSL (Secure Sockets Layer)?
400
This wireless technology is also known as IEEE 802.11.
What is wi-fi?
400
A standard for including routing information in the packets of an IP network. It can deliver the quality of service (QoS) required to support real-time voice and video as well as service level agreements (SLAs) that guarantee bandwidth.
What is MPLS (Multiple Protocol Label Switching)?
400
A technology deployed by telephone companies. It consists of a ring of fiber optic cable which can connect one business, several businesses, multiple business locations (network nodes) to carrier termination. It can be local or long distance carrier. It is commonly used as local access (last mile) technology because it allows faster, cleaner and more reliable data transmission. It is deployed as a ring. It can be shared or dedicated.
What is SONET (Synchronous Optical Network)?
400
This marks the beginning of a Data Packet
What is a Header?
500
This is the number assigned to the SSL application on the server.
What is Port 443?
500
They act as a central transmitter and receiver of Wireless Local Area Network signals.
What is an Access Point?
500
An interconnected group of networks that appears as one large network to the user. Defined by Banyan Systems as “the ability for users to transparently communicate locally and remotely across similar and dissimilar networks through a simple and consistent user interface.”
What is a virtual network?
500
Long, thin strands of very pure glass about the diameter of a human hair. They are arranged in bundles called optical cables and used to transmit light signals over long distances.
What are fiber optics?
500
This marks the end of a Data Packet
