Hardware are the part of a computer and to find out about hardware, we need to know what is computer? The word computer came from Latin word “compute”, which means, “to calculate” and its invented by Charles Babbage in 1822 which called Analytical Engine but if we go back to the 1940s and one of the first computers was the ENIAC which was based on vacuum tubes with over 17,00 of them weighing 30 tons altogether and taking up as much space as a large house. A computer is an electronic device that manipulates information, or “data” mean accept data and instruction as input, process data programs according to the given instruction and produce information as output. A program is a set of instructions that a computer can use to process data. Programs …show more content…

The CPU directs coordinates and communicates with the other components and performs all of the thinking, it is not really thinking what a CPU actually does is perform mathematical calculations, sends and receives information, completes tasks and puts the software to work.

Motherboard

The motherboard is the heart of the computer. It is the largest and most fundamental component of a PC and every other component is attached to it in some way. This is because all the different components use the motherboard to communicate and work each other. The motherboard has a series of slots, sockets and connectors for attaching the components of a PC. In most cases, the memory, accessory cards and CPU are installed directly onto the motherboard. The drives and peripherals communicate with motherboard through wired connections or directly.

Bios (Basic Input/output System)

Bios is an acronym for basic input/output system which help the computer to start up and load programmes. It is little chip that sit on the motherboard. The Bias’s primary function is to handle the system setup process including driver loading and operating system booting and it test the system, recognize the hardware devices. It is also contains a diagnostic program called power on self-test(Post) where its make sure all the different hardware components in system are working

    The Hefty Hardware case study presents multiple critical issues that will impact both short-term and long-term growth and development of the company. The first issue is the communication gap and lack of integration between stakeholders in business and the Information Technology division. The second critical issue is the lack of shared knowledge and each department working on projects in essentially silos. The third critical issue is internal company politics driving the executive-level decision making process. Solutions to the above issues will need to be addressed with utmost urgency to ensure Hefty Hardware’s foothold in the marketplace.

    Softwares are instructions, commands, or data that direct the operation of computer systems. Hardware is the physical aspect of computers, telecommunications, and other devices. Hardware such as electronic circuitry and other components of a computer use software or programs to make technology do things. Hardware is permanent and not flexible, while software or programming can easily be varied and modified. You can put an entirely new program in the hardware and make it create an entirely new experience for the user. People can change the modular configurations that most computers come with by adding new adapters or cards that extend the computer's capabilities.

  • The motherboard is the main circuit board of a microcomputer

    469 Words  | 1 Pages

    The motherboard is the main circuit board of a microcomputer. The motherboard contains the connectors for attaching additional boards. Typically, the motherboard contains the CPU, BIOS, memory, mass storage interfaces, serial and parallel ports, expansion slots, and all the controllers required to control standard peripheral devices, such as the display screen, keyboard, and disk drive. Collectively, all these chips that reside on the motherboard are known as the motherboard's chipset. On most PCs, it is possible to add memory chips directly to the motherboard. You may also be able to upgrade to a faster CP by replacing the CPU chip. To add additional core features, you may need to replace the motherboard entirely. (Glossary)

    In designing a computer system, architects consider five major elements that make up the system's hardware: the arithmetic/logic unit, control unit, memory, input, and output. The arithmetic/logic unit performs arithmetic and compares numerical values. The control unit directs the operation of the computer by taking the user instructions and transforming them into electrical signals that the computer's circuitry can understand. The combination of the arithmetic/logic unit and the control unit is called the central processing unit (CPU). The memory stores instructions and data.
