Difference between Basic Disk and Dynamic Disk
Both basic disk and dynamic disk are disk configurations available in the Windows Operating System. A basic disk has been available since the early days of DOS and Windows. Dynamic disk was introduced with Windows 2000 and offers more flexible storage management. Basic Disk Basic Disk configuration works on the concept of partitions, partition tables, and logical drives. A disk can have up to four primary partitions, or three primary partitions and one extended partition containing multiple logical drives. The following operations can be performed − Create/Delete primary or extended partitions Create/Delete logical drives within an ...
Read MoreDifferences between Data paths.
A CPU has two main sections: the data section (data path) and the control section. The data path consists of registers, ALU, and interconnection buses that carry out the actual data processing. Data paths are classified into three types based on how instructions are executed − Single Cycle, Multiple Cycle, and Pipeline. Single Cycle Data Path In a single cycle data path, each instruction completes in exactly one clock cycle. The clock cycle must be long enough to accommodate the slowest instruction, which wastes time for simpler instructions. Multiple Cycle Data Path In a multiple cycle ...
Read MoreOperating System Based Virtualization
There are several benefits to using operating system-based virtualization. You can run multiple operating systems on the same physical hardware. This can be useful for testing different operating systems, running legacy applications, or saving space on your computer. Another advantage is that it can improve performance. By isolating each operating system from others, virtualization software can prevent conflicts and improve overall system performance. It creates a layer of abstraction between the hardware and the operating systems. The virtualization software is installed on the host operating system. It manages this layer of abstraction and allows guest operating systems to access ...
Read MoreWhat is the Industrial Internet of Things (IIoT)?
Industry uses computers, such as production and power management. This integrates with embedded devices, gauges, and other equipment in the IIoT. The ability to gather, trade, and analyze data is possible through networking. This may also affect the economy. The IIoT is an improvement on a distributed control system (DCS). It enables more mechanization by streamlining and enhancing process capability by utilizing cloud computing. Industrial Internet of Things (IIoT)- What Is It? IIoT entails creating and deploying the Internet of things (IoT). It is in engineering settings and domains. The IIoT helps businesses and industries. You can operate more with ...
Read MoreOverview of Arduino IoT boards
Arduino has come up with a number of boards specifically for Internet of Things (IoT) applications. If you go to the Products page on Arduino website, you will find a separate section for IoT boards. Their prices range from $18 to $69.The main feature that differentiates these boards from other Arduino boards (like Uno) is the presence of some connectivity onboard. For instance, The Arduino Nano 33 IOT board has WiFi and Bluetooth connectivity.The MKR Fox 1200 board (available in Europe only) supports the Sigfox architecture.The MKR GSM 1400 board supports GSM.The MKR NB 1500 supports the recently developed NBIoT ...
Read MoreWhat are process states?
A process is a program in execution and it is more than a program code called as text section and this concept works under all the operating system because all the task perform by the operating system needs a process to perform the taskThe process executes when it changes the state. The state of a process is defined by the current activity of the process.Each process may be in any one of the following states −New − The process is being created.Running − In this state the instructions are being executed.Waiting − The process is in waiting state until an ...
Read MoreHow does the operating system act as a resource manager and extended machine?
An operating system is the interface between the user and the machine which controls and coordinates the use of the hardware among the various application programs for the various users. Operating System as Extended Machine Let us understand how the operating system works as an Extended Machine. At the Machine level the structure of a computer’s system is complicated to program, mainly for input or output. Programmers do not deal with hardware. They will always mainly focus on implementing software. Therefore, a level of abstraction is supposed ...
Read MoreWhat is computer architecture?
Computer architecture can be defined as a set of rules and methods that describe the functionality, management and implementation of computers. To be precise, it is nothing but rules by which a system performs and operates.Sub-divisionsComputer Architecture can be divided into mainly three categories, which are as follows −Instruction set Architecture or ISA − Whenever an instruction is given to processor, its role is to read and act accordingly. It allocates memory to instructions and also acts upon memory address mode (Direct Addressing mode or Indirect Addressing mode).Micro Architecture − It describes how a particular processor will handle and implement ...
Read MoreWhat is memory hierarchy?
The Computer memory hierarchy looks like a pyramid structure which is used to describe the differences among memory types. It separates the computer storage based on hierarchy.Level 0: CPU registersLevel 1: Cache memoryLevel 2: Main memory or primary memoryLevel 3: Magnetic disks or secondary memoryLevel 4: Optical disks or magnetic types or tertiary MemoryIn Memory Hierarchy the cost of memory, capacity is inversely proportional to speed. Here the devices are arranged in a manner Fast to slow, that is form register to Tertiary memory.Let us discuss each level in detail:Level-0 − RegistersThe registers are present inside the CPU. As they ...
Read MoreWhat is operating system design and implementation?
The operating system is needed to design and implement because without proper design and implementation any system cannot work properly, for every aspect or for any development a proper design and implementation should be necessary so that it can work in good manner and we can easily debug if any failures occur.So, design and implementation is a necessary part of an operating system and this technique can be used by every user who uses a computer.There are different types of techniques to design and implement the operating system.Design goalsMechanismImplementationLet us discuss each technique in detail.Design goalsLet us understand the features ...
