Types of Computer Systems

What is a Computer?

An electronic device that can perform a variety of computational functions is called a computer. Thus, to sum up, a computer is essentially a multipurpose electronic device that can be used for a wide range of tasks, such as sophisticated data analysis and scientific simulations, as well as standard word processing and web browsing....

Features of Computer System

User Interaction: Computer structures provide user interfaces, which include graphical consumer interfaces (GUIs) or command-line interfaces (CLIs), through which users can engage with and manage the system. Multitasking: Computer structures guide multitasking, allowing multiple applications or tactics to run concurrently and percentage device resources including CPU time, reminiscence, and storage. Versatility: Computer systems are flexible and might carry out a huge variety of responsibilities, from basic arithmetic calculations to complex information processing and multimedia programs. General Purpose: Several Computer systems are designed to be fashionable-motive, meaning they could run several designing software program packages and adapt to distinct personal wishes and requirements. High Performance: Modern laptop structures are geared up with effective processors, sufficient reminiscence, and rapid storage devices, letting them deal with annoying computational tasks correctly. Connectivity: Computer systems are ready with networking competencies, enabling communique and information to alternate with other systems and gadgets over neighborhood vicinity networks (LANs) or the net. Expandability: Computer systems are designed with expandability in thoughts, allowing customers to add or upgrade hardware components which include reminiscence, garage, and peripheral devices to decorate device talents. Operating System: Computer structures depend upon working systems (e.g., Windows, macOS, Linux) to manage hardware sources, offer a consumer-pleasant interface, and help the execution of software applications....

What is an Embedded System?

An embedded device is a part of an integrated system that is formed as a combination of computer hardware and software for a specific function and which can operate without human interaction.  An embedded system is a type of specialized computer system that is intended to carry out one or more particular functions. An embedded system is utilized in huge electronic or mechanical systems to carry out tasks with limits on real-time computing. The fact that embedded systems are typically a component of larger systems is the most crucial thing to remember about them. As such, the end users are not intended to use the embedded system as a stand-alone device....

Features of Embedded System

Dedicated Functionality: Embedded systems are designed for precise tasks or capabilities within a larger system or tool, such as controlling equipment, monitoring sensors, or processing facts in real time. Real-Time Operation: Many embedded systems require a real-time operation, in which tasks need to be completed inside strict timing constraints to ensure well-timed responses and deterministic conduct. Resource Constraints: Embedded systems generally have restrained resources, consisting of processing energy, memory, energy, and garage, to satisfy length, price, and electricity consumption requirements. Compact Form Factor: Embedded systems are often compact and included in the tool they control or monitor, minimizing physical footprint and external dependencies. Low Power Consumption: Embedded structures are designed to function efficiently within power-restricted environments, and regularly the usage of low-strength processors and optimized algorithms to minimize strength intake. Reliability and Stability: Embedded structures prioritize reliability and stability, as they’ll be deployed in challenge-important programs in which downtime or failures will have critical consequences....

Difference Between Computer and Embedded System

Category Computer Embedded device Description A computer is a combination of hardware and software resources that integrate and provide various functionalities to the user. An embedded device is part of an integrated system that is formed as a combination of computer hardware and software for a specific function and which can operate without human interaction. Human Interaction A computer needs Human Interaction to perform tasks. Embedded devices do not need Human Interaction to perform tasks. Types based on architecture Analog computer, Digital computer, Hybrid computer, Harvard architecture, Von Neumann architecture, Reduced instruction set computer Small Scale Embedded Systems, Medium Scale Embedded Systems, Sophisticated or Complex Embedded Systems Parts It has 2 parts: Hardware and Software. It has 3 parts: Hardware, Firmware, and Software. Tasks It can perform many tasks. It performs limited tasks. Cost to user The user has to pay more for a computer. The user incurs a lesser cost for an embedded system. Peripherals Computers have peripherals such as keyboards and mice, displays, printers, Hard disk drives, floppy disk drives, optical disc drives, etc. Embedded Devices have peripherals such as Serial Communication Interfaces (SCI), Synchronous Serial Communication Interfaces, Universal Serial Bus (USB), Multi Media Cards (SD cards, Compact Flash), etc. Purpose Computers can be reprogrammed for a new purpose. Embedded Devices are made only for a specific set of purposes. Power Consumption The computer needs more operational power than Embedded Devices. An embedded Device needs lesser operational power than a Computer. Complexity Computers are more complex devices than Embedded Devices. Embedded Devices are less complex devices than Computers. Need of another device Computers may be installed in other devices but are self-sufficient to exist. Embedded Devices only exist inside other Systems. Usage Difficulty Computers are more Difficult when used, compared to an Embedded System. Embedded are easier to use than Computers. User Interfaces It requires more user interface than Embedded Devices. It requires less to no user interface than Computers. Time Specificity Computers are not time-specific. They may need to perform tasks that are not time-bound and take days to perform as well. Embedded Devices are time-specific. The tasks assigned to them need to be performed within a specific time frame. Size Computers are usually bigger with larger hardware and input-output devices attached to them. Embedded Devices are smaller in size than Computers, with limited hardware. Developed in 1833 A.D. 1965 A.D. Developer Charles Babbage Charles Stark Draper Memory Requirement Computers have larger memory requirements due to a lot of storage of data. Embedded Devices need less Memory....
