Nslookup
The software systems which manage the interaction between users and hardware.
Operating system
A configuration and management option which is either connected to a test network or no network at all in order to ensure secure configuration.
Out-of-Band Management
An error detection procedure used in redundancy solutions
Parity
A terminator which and a connection in SCSI’s.
Passive Terminator
A piece of software designed to update or fix problems with a computer program or its supporting data.
Patch Management
A computer bus for attaching hardware devices in a computer.
PCI (Peripheral Component Interconnect)
A function which includes a single performance chart accompanied by an interpretation of the results, based on an environment.
Performance Baseline
a function which provides information as to how well the operating system or and application, service, or driver is performing.
Performance Counters
A set of actions or items which a user or computer is allowed to access or control.
Permissions
Measures taken to prevent physical access to equipment or data.
Physical Security
An activity which occurs when the processor is so busy that it cannot respond to a request for a time.
Processor Bottlenecks
A technology which allows high levels of storage reliability through various implementations of mirroring, striping, and parity.
RAID (Redundant Array of Independent Disks)
also known as a stipe set, is a technology which splits data evenly across two or more disks.
RAID 0
Also known as mirroring, is a technology which creates a copy of a set of data to be placed on two or more disks in order to increase reliability.
RAID 1
A technology which allows storage reliability using block-level striping with parity.
RAID 5
An availability solution which entails the distribution of data to multiple locations.
