The 3 most common network operating systems are MS Windows Server, Novell Netware, and Unix.
Define TOPOLOGY.
Topology is the DESIGN and LAYOUT of network devices and the CABLING that connects the devices.
What is "Client for NFS"?
Client for NFS is the GENERIC TERM FOR A UNIX CLIENT.
What is LDAP?
LDAP is LIGHTWEIGHT DIRECTORY ACCESS PROTOCOL, a vendor neutral directory service.
A _____ topology is a single cable with computers attached to it.
A BUS topology is a single cable with computers attached to it.
A central hub with cables radiating out to computers is a _____ topology.
A central hub with cables radiating out to computers is a STAR topology.
A _____ topology has redundant connections to all computers.
A MESH topology has redundant connections to all computers.
An outer loop connecting all computers is a _____ topology.
An outer loop connecting all computers is a RING topology.
A bus topology must have a _____ or _____ at each end.
TERMINATOR or REPEATER
The main communication cable for a network.
BACKBONE
An electricaly powered device that allows multiple cable-connected nodes to comunicates with each other.
HUB
A device that communicates via a network interface card and is attached to the network.
NODE
(commonly a computer or printer)
A device that reenerates an electrical signal when the maximum length of a cable has been reached.
REPEATER
A subdivision of a larger network
SEGMENT
The process of logging onto a network and having your identity verified by a username and password.
AUTHENTICATE
Software that allows a workstation to properly communicate to a specific network operating system and servers.
CLIENT
The system by which directories are shared between computers in Unix.
NFS (Network File System)
Unix servers that maintain a network based file of usernames, groups and passwords.
NIS and NIS+ (Network Information Service)
Maintains the master database of usernames, passwords and groups. At least one is required by every domain.
PDC (Primary Domain Controller)
Used in Microsoft Windows networks to offload user authentications from the PDC. A single domain can have more than one of these.
BDC (Backup Domain Controller)
Computer that provides services such as network authentication, file sharing, printer sharing, e-mail, Web services and database access.
SERVER
The basis for Novell's global directory services.
TREE
Command-line based network operating system that originated in scientific and academic circles.
UNIX
A loose collection of computers that are single-server based and, as such, have separate, unrelated databases of users, groups and passwords.
WORKGROUP
High-end desktop computer with a lot of RAM and a fast CPU to support sophisticated business apps.
WORKSTATION
Specifications created by the International Telecommunications Union (*ITU) to define global standards for directory services.
X.500
When two hard drives have separate controllers and contain duplicate information.
DUPLEXING
Multiple drives grouped together and seen by the operating system as a single drive
LOGICAL DRIVE
_____ is where a duplicate image of a primary hard drive is kept on a second disk and a single controller manages both drives.
MIRRORING
Hard drives that have data spread across them for fault tolerance or speed enhancements.
RAID (REDUNDANT ARRAY OF INDEPENDENT DISKS)
Data spread across multiple disks in small portions. Parity info is also spread out and is used to rebuild data that is lost if a drive fails.
STRIPING (WITH PARITY)
Data is spread across multiple disks in small portions. Parity information is NOT recorded. All drives read and write at the same time. Fastest type of system storage. No fault tolerance to handle a drive failure.
STRIPING (WTHOUT PARITY)
Data copied to tape cartridges for disaster recovery.
TAPE BACKUP
A logical division, such as a drive letter.
VOLUME
What are the directory services used by NetWare?
NDS (Novell Directory Services)
Microsoft uses what naming convention to designate a collection of standalone systems?
Workgroup. A loose collection of computers with separate user databases.
A tree is used to represent the directory services of which operating system?
Novell Netware.
None
What technology does Unix use to share directories on servers?
The network File System (NFS) mounts share server directories to a local workstation.
What is the maximum number of repeaters that can be used in a single bus network?
FOUR repeaters can connect up to five sections.
What kind of number is applied to a source IP address to determine whether destination addresses are within or outside of the same network.
SUBNET MASK
What is the common name for RAID level 1?
MIRRORS
What is the hard disk configuration that has the fastest reads and writes?
Striping without parity
Which RAID level has a dedicated parity drive?
RAID 3
What method of preserving data will allow you to sustain damage to an entire site?
Tape backup
Which layer of the OSI model provides a reliable, connection-oriented datastream?
Transport
Which layer of the OSI manages dialog between two network nodes?
Session
Which layer of the OSI contains both the Logical LInk Control sublayer and the Media Access Control sublayer?
Data Link
Which layer of the OSI provides routing functionality?
Network
Which layer of the OSI is responsible for services such as electronic messaging?
Application
OSI layer that handles data-format issues such as encryption and compression
Presentation
OSI layer that places data on the wire and manages signaling
Physical
Two devices that operate at the Network layer
Router and brouter
Topology that consists of a central device with end nodes connected in point to point links
Star
Topology that is a multipoint connection where all computers access the same single cable
bus
Topology consisting of multiple, redundant, point to point links
Mesh
Topology that uses a tremendous amount of cabling, raising costs
mesh
One disadvantage of this topology is that cable faults are difficult to locate and disable the entire segment
bus
Device which requires ring-in ports to be connected to ring-out ports for two to be connected
MAU
Best option to connect to a backbone
Segment
Security level based on knowing the password to a resource (file,printer, etc.)
