FireWire and Thunderbolt are two types of high-speed data transmission interfaces used to connect various electronic devices to computers, such as cameras, hard drives, and other peripherals. Thunderbolt provides faster data transfer rates, power delivery, and a shorter cableĀ length than FireWire, but it is more expensive and not as widely available. Read this article to find out more about Firewire and Thunderbolt and how they are different from each other. What is Firewire? FireWire uses a serial bus architecture, which means data is transmitted one bit at a time through a single cable. This allows for rapid and effective ... Read More

In digital electronic systems, a register is a basic memory element used to store and manipulate data in binary form. A register is basically a group of flip-flops, where a flip-flop is a one-bit storage device. The storage capacity of a register depends on the number of flip-flops used within the register. Registers are commonly used in different parts of a digital electronic system like processor, arithmetic unit, memory unit, etc. Based on the application and functionality, registers are classified into various types, such as data registers, shift registers, memory registers, etc. In this article, we will explore ...

Cache memory is an important component in a modern computing system that compensates for the difference between the speeds of the CPU and the main memory. The main function of cache memory is to store the most frequently and recently used data and instructions. This reduces the time required by the CPU in retrieving data and instructions that are frequently required for processing. In this article, we will explore cache memory and its performance, and also how it enhances the efficiency of a computing system. Cache Memory Basics Cache memory is the small and fastest memory used in a computer ... Read More

Cache memory is small and fast computer memory used in computer systems to enhance their performance by increasing processing speed. It is a small memory component provided between the main memory (RAM) and the CPU (Central Processing Unit) of the computer system. It acts as a buffer between the RAM and CPU, and it stores recently and frequently used data and instructions. Cache memory has a speed typically equal to the speed of the processor, reducing the time required to access data. Therefore, by providing data and instruction at faster speed, it helps to speed up the data processing ... Read More

Memory protection is a crucial component of operating systems which permits them to avert one method's storage from being utilized by another. Memory safeguarding is vital in contemporary operating systems since it enables various programs to run in tandem lacking tampering with their respective storage space The primary goal of safeguarding memory is to avert an application from accessing RAM without permission. Whenever an approach attempts to use memory that it does not have permission to enter, the computer's operating system will stop and end the process. This hinders the program from obtaining memory that it should not. Memory backup ... Read More

Overlay memory management technique allows multiple programs to be loaded into memory simultaneously, but only a portion of each program is resident in memory at any given time. This is used to increase the overall memory utilization and efficiency of the computer system. The technique swaps different parts of the programs in and out of memory as required. The overlay memory management technique is commonly used in situations where the memory requirements of the programs exceed the available physical memory. In such cases, the operating system can load the program into the memory in smaller sections, known as overlays. Each ... Read More

In an operating system, segmentation is termed a memory management technique where the memory is divided into segments that can be allocated to a process. These segments may not be in fixed length and not stored in a contagious manner. This approach has been developed after the paging process which takes multiple pages for a process to get loaded into main memory, whereas segmentation divided the code into segments as its relative code can be merged to form a single block. The segment table holds all the details relating to the segments and the processes. Generating a logical address which ... Read More

In the operating system, segmented paging provides better performance and utilization of the CPU as it combines the process of segmentation and paging. Segmentation is termed a memory management technique where the memory is divided into segments that can be allocated to a process. These segments may not be in fixed length and not stored in a contagious manner. The segment table holds all the details relating to the segments and the processes. Generating a logical address which is converted to a physical address by the CPU by refereeing to the segment table. This table contains two fields about the ... Read More

Resource Allocation

When each process request for the resources available in the system, the operating system allocates the needed resources for its execution purpose. The resources allocated can be either a hard drive, scanner, any files in memory, or even a printer. Any program that enters into a ready or execution state is termed a process. This program requires resources from one or other processes to complete its assigned task. In a multiprogramming environment, a process may request multiple resources at the same time, so those processes have to be waiting until it receives all the resources. A resource allocator present in ... Read More

A routine is said to be a computer program with a set of instructions that is used for the execution of the system program. They allocate or deallocate the memory used after completion of its execution as per instructions given as routine-routine or even functions. The process is termed as the programs that are currently in execution state and utilizes the resources of CPU. Each process undergoes different states like active, new, ready, block, and wait, suspended during its life cycle. Multiprogramming environment is done to the processes which require it, where each process is classified into preemption and non-preemption ... Read More
