Lesson 4 Pt. 2 Flashcards
A group of interconnected computer systems
Computer Network
Two or more computers are linked together with a medium and data communication devices
Computer Network
A computer network used for communication among “computer devices close to one person”, such as the computer system’s is hospital departments
Personal Area Network (PAN)
What type of network for hospital departments
Personal Area Network
A small computer network covering a “small physical area” such as hospitals and inter department
Local Area Network (Lan)
Current wired LANs are most likely to be based on ______
Ethernet Technology
A network that connects “two or more local area networks” but does not extend beyond the boundaries of immediate town/city
Metropolitan Area Network
Computer networks that cover a broad area
Wide Area Network (WAN)
A network that uses routers and public communication skills
WAN / Wide Area Networks
The largest and most well known example of WAN is the _____
Interneg
It is a data communication network that covers a relatively broad geographic area
WAN
The context of a communication network that refers to “the way the computers or workstations in the network are linked together”
Network Topology
3 Type of Network Topology
Star Topology
Bus Topology
Ring Topology
A topology: all work stations are connected to a single communication line
Bus Topology
A topology: a number of workstations are directly linked to a central station called node
Star Topology
Responsible for controlling all the activities of the substations
Central workstations
The advantage of this topology is that any signal transmitted on the network passes through all the LAN stations
Ring Topology
This topology is transmitted in one direction only
Ring Topology
Any software that is available to use free
Freeware
This software can be downloaded and installed over the Internet without any cost
Freeware
Software applications that are paid programs, but are made available for free for a limited time of period
Shareware
This software allows you to test drive the software before you actually invest to purchasing it
Shareware
This is a type of software that has an open source code that is available to use for all
Open Source Software
Types of software that are non-free for programmers
Close Source Software
