CASE

Reading : Case
Full spelling : Computer Aided Software Engineering
Field :
Programming enviroment for software development CASE

Abbreviationof "computersupport software engineering". Integration of the system software development tools and development methodology and improvement of efficiency of system development job are designated as purpose. It is possibleto automate manyaspectsof software development making use of the software which is called the CASE tool. There is a high-level CASE tool which supports, the early stage of software development such as plan design and a down stream CASE tool which supports program compilation test maintenance and the like in the CASE tool,the seprocess lumps together entirely and it calls those which correspond the integrated CASE tool.

CASL II
Field :
IT industry qualification national qualification CASL II

Assembly language forthe computer "COMET II " which is designed formaking questionstheNational Examination for Information Processing Technicianshypothetically. It was newly founded in 2001 with at oneof the programming languages which are made questions "basicinformation technician" test, CASL II andC language,frommidstof the four of Java and COBOL selecting one, you answer.

Anythingother than the inside CASL II of four programming languages because public standard and the common specification which corresponds to that exist, is made questions in the language specification which conforms to that. But,assembly language(andmachine language) because the product of individual enterprise (every series) it is specific, the information processing propulsion mechanism which is the making questions person (IPA) defining the specificationof COMET II whichisthe hypothetical computer, it decides the specification of CASL II on that. ... The continuation is read

This way, CASL II is assembly language of the computer whichreally does not exist, but the examinee in order to be able to train CASL II programming,when there isalsoan enterprise whichdevelops the emulator of COMET II, purchases this starting COMET IIhypothetically onthe personal computer, it is possible to execute the program which describes with CASL II.

Furthermore,it is predecessorof the basic information technician, with"second kindinformation processing technician " test, virtual machine "COMET" and the assembly language "CASL" which operateson that was used.Becauseprogress of the technology regarding the basic design of the computer the eye it is apparent,the COMET II which undertakessuccession attendant upon the movement to the basic informationtechnician, CASL II was defined anew.

CAS latency

Full spelling : Column Address Strobe latency
Alias :
CL
Field :
Semiconductor memory RAM CAS

Oneof the efficiency indicesof SDRAM which is used in main memory of the personal computer.The semiconductor storage cell has lined up into lattice condition in memory, the case where reading and writing of the data is done, line of the element which becomes the object (row) with the line (column) it is necessary to appoint. The signal which appoints the line CAS (column address strobe) is called the signal, but after this signal being issued, until reading and writing of the data is really done, thing of the delay time which catches is called CAS As for the unit of time,frequencyof issue of the clock pulse which is usedinsame period of each circuit inside the computer (the number of clocks) it is used.There is the inscription "of CL=2" "CL=3" and so on in the specification chart of memory, but this has shown the fact that CAS catches 2 clocks and 3 clocks respectively. The extent operating speed where this value is small generally is fast.
