Computer Analysis Chap 14

Front 1

MRP-Material requirements planning

Back 1

- Approach to information management in a manufacturing enviroment that uses software to help monitor and control processes realted to production. Focuses on invetory parts.

Front 2

OIS-Office information system

Back 2

-info that enables employees to perform tasks using computers and other elcetronic devices, instead of manually. Also called office automation.

Front 3

TPS-Transaction processing system

Back 3

-Info system that captures and processes data from day to day business activities. Transaction referring to individual business activity

Front 4

MIS-Management information system

Back 4

-Info system that generates accuarate, timely, and organized information, so managers and other users can make decisions, solve problems, sepervise activities, and track progress.

Front 5

DSS-Decision support system

Back 5

-information system that helps users analyze data and make decisions. Uses data from internal and external sources as needed

Front 6

AI

Back 6

-application of human intelligence on a comp

Front 7

Expert system

Back 7

information system that captures and stores the knowledge of human experts and then imitates human reasoning and decision making

Front 8

RAID

Back 8

redundant array of independent disks group of two or more intefrated hard disks that acts like a single large hard disk, more reliable than traditional hard disks

Front 9

Mirroring-

Back 9

RAID storage design that writes data on two disks at the same time to duplicate the data. Also called level 1. Enhances reliablility

Front 10

Stripping

Back 10

RAID storage technique that splits data, instructions, and information across multiple disks in the array. Improves access time.

Front 11

RAID 0

Back 11

Stripping without parity, no fault no tolerance, high performance, extremely difficuly recovering in case of disk failure. RECOMMENDED USES: non critical data or data that changes infrequently and is backed up regularly) requiring high speed, particularly write speed, and low cost implementation. Audio and video streaming and editing;web servers;graphic design; high end gaming or hobbyist systems; temporary or "scratch" disks on larger machines

Front 12

Indexing

Back 12

the process of arranging content so that it can later be searched

Front 13

RAID 1

Back 13

Mirroring or Duplexing-complete redundancy, hurts write performance, improves some read performance. RECOMMENDED USE:Applications requiring high fault tolerance at a low cost, without heavy emphasis on large amounts of storage capacity or top performance. Is popular for accounting and other finacial data. It is also commonly used for small database systems, enterprise servers

Front 14

RAID 5

Back 14

Block level stripping with Distributed parity, good performance, good fauly tolerance, high capacity storage efficiency, best suited for TPS and ERP systems, performance degrades in high write situations. RECOMMENDED USE: seen by many as the ideal combination of good performance, good fault tolerance and high capacity and storage efficiency. it is best suited for trnasaction processing and it is often used for "general purpose" service, as well as for relational database applications

Front 15

Blade Server

Back 15

Complete computer server, such as a Web server or network server, packed on a single card. Also called ultradense servers. Saves space, requires less maintenance, uses less energy, generates less heat, and is easily replaced or upgraded

Front 16

Scalability

Back 16

measure of how well computer hardware system, software application, or info. system can grow to meet increasing needs. adding hardware is often the easiet method to grow.

Front 17

Backups

Back 17

four different kinds: Full, differential, incremental, selective
