what is the difference between random access and dynamic access in cobol?
237264
random access mean you randomly locate the record using RBA for ESDS , RRN for RRDS and Primary key for KSDS and your search goes record by record. dynamic access means you dynamically locate a record and from there you perform sequential operation.

A variable is a named memory location which temporarily stores data that can change while the program is running. A constant is a named memory location which temporarily stores data that remains the same throughout the execution of the program. The type of a variable indicates what kind of value it will store.

Answer: In an array, you have a list of elements and you can access any of them at any time. But in a stack, there's no random-access operation; there are only Push, Peek and Pop, all of which deal exclusively with the element on the top of the stack. A stack is data-structure which has a last in first out policy.

Arrays allow random access and require less memory per element (do not need space for pointers) while lacking efficiency for insertion/deletion operations and memory allocation. On the contrary, linked lists are dynamic and have faster insertion/deletion time complexities.

Dynamic RAM has to be dynamically refreshed all of the time or it forgets what it is holding. ... So static RAM is fast and expensive, and dynamic RAM is less expensive and slower. Therefore static RAM is used to create the CPU's speed-sensitive cache, while dynamic RAM forms the larger system RAM space.

malloc is not a system call. It is implemented in libc and uses brk()/sbrk() and mmap() system call. Refer to Advanced Memory Allocation for more details.

Static arrays are allocated memory at compile-time and the memory is allocated on the stack. Whereas, the dynamic arrays are allocated memory at the runtime and the memory is allocated from the heap. ... ... What is the difference between an array of pointers and a pointer to an array using suitable example?

The EXTERNAL and GLOBAL clauses allow you to share data and files between different COBOL subprograms. EXTERNAL is used to access globally declared data, including data declared EXTERNAL by other COBOL programs. GLOBAL is only applicable when sharing data among nested programs in an ANSI85 dialect.

DIMM and SIMM are two major types of random-access memory standards for personal computers. DIMM is an acronym for “dual in-line memory module,” while SIMM stands for “single in-line memory module." The naming of each type of RAM refers to the specific way in which the memory is packaged.

The default access modifier in Apex is private, while in Java it is default. public in Java is not same as public in apex. public in Apex means the method or variable can be used by any Apex in this application or namespace. if you want to make something public like it is in Java, you need to use the global.

It is imperative, procedural and, since 2002, object-oriented. COBOL is primarily used in business, finance, and administrative systems for companies and governments. COBOL is still widely used in legacy applications deployed on mainframe computers, such as large-scale batch and transaction processing jobs.

The main difference between static and dynamic hashing is that, in static hashing, the resultant data bucket address is always the same while, in dynamic hashing, the data buckets grow or shrink according to the increase and decrease of records. ... There are two types of hashing called static and dynamic hashing.

Static arrays, sometimes simply called arrays, are allocated with a fixed size while dynamic arrays increase their size when an insertion occurs and the array currently has no space for the new value.

Sequential access means given an element, I can access the next one, or maybe the previous one, just as easily as accessing the given element. Eg: linked list. Random/direct access means given an element, I can access any other element in the structure just as easily.

That's MIPS Assembly, one that I am not so experienced with, due to lack of hardware. But as far as I know, the ADD is adding a value, which can be an immediate, while the ADDI is explicitly adding an immediate. The difference should be, as you can see, that the immediate value in the first one is limited to 5 bits.
