Difference between Stack, Heap, and Queue
Stack, heap, and queue are ways that elements are stored in memory. Stack elements are added to the top of the stack, and removed from the top of the stack. The mnemonic LIFO is used to describe a stack (Last-In-First-Out). With a queue, the first one in is the first one out. The mnemonic FIFO is used to describe a queue. A heap is an area of memory where elements can be stored and removed in any order. More ...
Multiuser Operating System Functions
Some operating system functions like resource allocation, accounting, protection and security exist not for helping the user, but rather for ensuring the efficient operation of the system itself. More ...
Multi-Processor Scheduling
Here, we discuss several concerns in multiprocessor scheduling in the context of Multicore, Multithreaded core, NUMA (Non-uniform memory access), and Heterogeneous multiprocessing architectures. More ...
CPU Process Memory Address Binding
For a program to run on a CPU it must be brought from files in long-term, non-volatile storage to main memory. Addresses in the source program must be mapped to addresses in main memory. More ...
Processor Affinity in Symmetric Multiprocessing
Processor Affinity refers to a process's tendency to continue running on the processor on which it is currently running. When a process executes on a CPU, that process's cache is populated with its most recently accessed data, if a process is moved to a different CPU, that second processor's cache must be populated with that data. More ...
Operating System Boot
The procedure of starting a computer by loading the kernel is known as booting the system. On most computer systems, a small piece of code known as the bootstrap program or bootstrap loader locates the kernel loads it into main memory, and starts its execution. More ...
Multithreaded Programming Process' and Threads
A process generally has a complete, set of private resources, each process has its own memory space. Threads exist within a process, every process has at least one. Threads share the process's resources, including memory and open files. More ...
Binary Floating-Point Numbers
Floating-point numbers allow you to use the very large, and very small, numbers commonly found in scientific calculations. A binary floating-point number consists of three parts, the sign bit, the mantissa and the exponent. More ...
The Evolution of Hard Disk Bit Recording
Hard drive technology has continuously improved over the decades, that includes higher storage capacity performance. Part of this improvement has been higher access speeds, but most of the higher storage capacity has been the result of changes in the bit recording methods. More ...
AMD Sempron Processor
The Sempron replaced the Duron as AMD's budget processor. The socket A Sempron is basically an Athlon XP with half the cache. The socket 754 Sempron is a cut down version of the Athlon 64 processor with half the cache. More ...
Oscilloscope Required for Serious Digital Electronics Work
The oscilloscope is an instrument that displays digital signals on a line graph with time on the horizontal axis and voltage on the vertical axis. It will be difficult to do digital logic design without the use of an oscilloscope. More ...
CPU Process Scheduling
CPU scheduling is the basis of multiprogrammed operating systems. By switching the CPU among processes, the operating system can make the computer more productive. More ...
