Fundamentals of hardware and software components

Review all options available. The central processing unit, or CPU, is that part of a computer which executes software program instructions.

Computer - Hardware

System cooling is required to remove the waste heat produced by computer components, to keep components within permissible operating temperature limits. The motherboard, also referred to as system board or main board, is the primary circuit board within a personal computer, and other major system components plug directly onto or cable into the motherboard.

Using one of the vendor options available, test your system to determine how much RAM and what type is installed in your system. Click on a question to see the answer.

Audio cards are internal computer expansion cards that facilitate economical input and output of audio signals to and from a computer under control of computer programs, also known as a sound card. Convert the values to decimal to check your work. Solid state drives SSD are data storage devices using integrated circuit assemblies as memory to store data persistently.

Mass storage devices such as hard drives store programs and data even when the power is off; they do require power to perform read and write functions during usage. A modem modulator-demodulator is a device that modulates signals to encode digital information and demodulates signals to decode the transmitted information, initially used for telephone line data transmission, but also used with DSL and cable high speed connections.

How recent is your hardware? Experiment with converting decimal values to hexadecimal and binary, and then back to decimal again. Lesson Summary[ edit ] The central processing unit, or CPU, is that part of a computer which executes software program instructions.

The power supply unit, or PSU, converts general purpose electric current from the mains to direct current for the other components of the computer. Search the Internet for how to run the lshw List Hardware utility on your Linux distribution.

Optical drives, including CD, DVD, and Blu-ray Disc, are data storage devices using rapidly rotating discs coated with reflective material and read using a laser diode. Review Linux Man Page: What is System Information?

Liquid cooling uses a liquid rather than air as the heat conductor, with the most common heat transfer fluid in desktop PCs being de-ionized water. Hard disk drives HDD are data storage devices used for storing and retrieving digital information using rapidly rotating disks platters coated with magnetic material.

Restart your system and access the BIOS configuration screen.Different software applications can be loaded on a hardware to run different jobs. A software acts as an interface between the user and the hardware.

If the hardware is the 'heart' of a computer system, then the software is its 'soul'. Software - Computer programs and related data that provide the instructions for telling computer hardware what to do and how to do it Hardware and Software have a symbiotic relationship, this means that without software hardware is very limited; and without hardware, software wouldn't be able to run.

Section 1-Fundamentals of Hardware and Software Lesson 2- Hardware Components explain the four basic operations of a computer system after analysing a mini case. Computer Fundamentals: Introduction to Computer, Uses of Computer, Main Components of Computer, Input Devices, Output Devices, Hardware, Software, Operating System, and Internet [Steven Bright] on *FREE* shipping on qualifying offers.

Productivity in work place in many professions now requires the know 3/5(1). Without software most hardware are useless. Backing Store: Storage external to the computer used for large quantities of data or large programs.

Backing store is also known as secondary store, auxiliary store or external store. Hardware refers to the physical parts or components of a computer. Hardware includes components such as the monitor, keyboard, hard drive disk, mouse, printers, graphic cards, sound cards, memory, motherboard and chips, etc.

This lesson covers internal computer components.
