This diagram represents five contiguous memory regions which each hold a pointer and a data block. The List Head points to the 2nd element, which points to the 5th, which points to the 3rd, thereby forming a linked list of available memory regions. A free list (or freelist) is a data structure used in a scheme for dynamic memory allocation.
This is an example of a scaffold. Scaffolding is a technique used in bioinformatics.It is defined as follows: [1] Link together a non-contiguous series of genomic sequences into a scaffold, consisting of sequences separated by gaps of known length.
the stride of an array, or the amount of memory occupied by each element of the array. A program then can refer to the array (or other dope-vector-using object) by referring to the dope vector. This is commonly automatic in high-level languages. Getting to an element of the array costs a tiny bit more (commonly one instruction, which fetches ...
The memory cell is the fundamental building block of computer memory. The memory cell is an electronic circuit that stores one bit of binary information and it must be set to store a logic 1 (high voltage level) and reset to store a logic 0 (low voltage level). Its value is maintained/stored until it is changed by the set/reset process.
A page, memory page, or virtual page is a fixed-length contiguous block of virtual memory, described by a single entry in a page table.It is the smallest unit of data for memory management in an operating system that uses virtual memory.
With virtual memory, a contiguous range of virtual addresses can be mapped to several non-contiguous blocks of physical memory; this non-contiguous allocation is one of the benefits of paging. [8] [3] However, paged mapping causes another problem, internal fragmentation. This occurs when a program requests a block of memory that does not ...
A contig (from contiguous) is a set of overlapping DNA segments that together represent a consensus region of DNA. [1] In bottom-up sequencing projects, a contig refers to overlapping sequence data (); [2] in top-down sequencing projects, contig refers to the overlapping clones that form a physical map of the genome that is used to guide sequencing and assembly. [3]
Memory architecture describes the methods used to implement electronic computer data storage in a manner that is a combination of the fastest, most reliable, most durable, and least expensive way to store and retrieve information. Depending on the specific application, a compromise of one of these requirements may be necessary in order to ...
