Fig: functions of the operating systems 1 1- Hardware Hardware consists of physical equipment of the computer. We distinguish equipment within the Case such as: Power supply: it is the equipment that receives electricity from a DC current and converts it to a alternative current AC for the needs of the computer.

The power supply may depends on the motherboard…. Current trends in hardware and software include the increasing use of reduced instruction-set computing, movement to the UNIX operating system which is the development of large software libraries, microprocessor-based smart terminals that allow remote validation of data, speech synthesis and recognition, application generators, now in fourth-generation languages, computer-aided software engineering, object-oriented technologies, and artificial intelligence.

The computer industry and its products…. The Basic Computer Hardware Central Processing Unit: The central unit is the basic part of the computer and includes all the main computer parts. It is the heart of the computer system. All rights reserved. Computer science Hardware vs software components.

Nov 18, - 7 min read. Today, we will learn: Hardware vs. Software Hardware components Software components How do you design software? What to learn next Take the first step to becoming a computer scientist This course is the ideal place to start you computer science journey.

Hardware vs. Software Software describes a collection of programs and procedures that perform tasks on a computer. There are three general types of software: System software Programming software Application software When you think of computer science, software is probably what comes to mind.

Hardware Software Physical devices that store and run software Collection of coded instructions that all us to interact with a computer Works as the delivery system Performs specific tasks Monitor, printer, scanners , label makers, routers and hard drive Adobe, Google Chrome, Microsoft Excel, Spotify Hardware begins functioning when software is loaded.

It is comprised of two sub-units: The control unit CU : controls data flow from and into the main memory The arithmetic and logic unit ALU : processes the data Von Neumann architecture This computer architecture design, created by John von Neumann in , is still used in most computers produced today. The Von Neumann Architecture. Input and output units The input unit takes inputs from the real world or an input device and converts that data into streams of bytes. Storage Units After the data is retrieved and converted, it must be stored in the memory.

Storage Unit example. Keep the learning going. Machine language A computer can only process binary: a stream of ones and zeros. Assembly language Assembly language is a human-readable instruction mode that translates binary opcode into assembly instruction.

Assembler An assembler translates an assembly language program into machine language. Example of "Hello World" in Python. How do you design software?

Software design includes three levels: Architectural Design: an abstract version of the program or system that outlines how components interact with each other.

High-level Design: this part breaks the design into sub-systems and modules. High-level design focuses on how the system should be implemented. Detailed Design: this part deals with the implementation. Cabinet A cabinet is nothing but the case, either plastic or metallic enclosure that capsules almost all the other hardware.

Motherboard Motherboard is a large IC board that connects the other small hardware with the other peripherals. These cards are useful when the computer is to be connected to any other peripheral devices or another computer through a network. Data Storage Devices- Hard Disks are magnetic discs that store data in the digital format. This is a secondary storage device and fundamental component of a computer.

Peripheral Devices Any device that is connected to the computer and does not serve the primary purpose is called a peripheral device. Few examples of peripheral devices are.
