•Where do we use computer 

We are use computer in the homes, business, educational institutions, research organizations, medical field, government offices, entertainment,etc.

•Identify with specific components of computer where mostly used 

Motherboard

A complete computer components list always starts with the motherboard, the primary circuit board that holds all the hardware in place. Every PC has one, from dedicated workstations to personal notebooks.

Central Processing Unit (CPU)

The central processing unit (CPU) - commonly referred to as the processor - is the ‘brain’ of your computer. The CPU solves all the sophisticated algorithms and programming your computer does while running programs or applications.

Graphical Processing Unit (GPU)

When handling graphical operations and advanced imagery, the graphical processing unit (GPU) is the computer hardware responsible for it. A GPU is required for your computer to read and reproduce graphical representations and effects, which are almost present in every form of media today.

Random Access Memory (RAM)

Computers have different forms of memory that store information and data, and the more prominently discussed is random-access memory (RAM). A RAM device keeps important currently-used data and codes on standby, loading them instantly when respective programs or apps are opened.

Storage device

A storage device provides the memory for installing programs and saving files. Unlike RAM, a storage device’s content is secured in non-volatile memory, meaning that data is saved permanently inside its memory bank, preserving them even after you turn off the PC (unless manually deleted or uninstalled)

Power supply

A power supply provides electricity to all components of a computer system. Typically, it's a power cord connected from the back of a PC tower into an electricity socket. A technician may troubleshoot the power supply by turning off the computer, unplugging and detaching the power supply cord or trying a new cord or outlet.

Hard drive

Hard drives are data storage devices used to store files, programs or other information on a computer system. They use magnetically coated discs called hard disks that store digital representations of information. If a hard drive fails, a computer technician may suspect a corrupt hard drive. They may use data recovery software to repair the computer or may replace the hard drive.

•Illustrate hoe the computer works using the hardware entities

Hardware refers to the computer's tangible components or delivery systems that store and run the written instructions provided by the software. The software is the intangible part of the device that lets the user interact with the hardware and command it to perform specific tasks.

On mobile devices and laptop computers, virtual keyboards are also considered software because they're not physical.

Since the software and hardware depend on each other to enable a computer to produce useful output, the software must be designed to work properly with the hardware.

The presence of malicious software, or malware, such as viruses, Trojan horses, spyware and worms, can have a huge effect on computer programs and a system's OS. Hardware is not affected by malware, though.

However, malware can affect the system in other ways. For example, it can consume a large portion of the computer's memory or even replicate itself to fill the device's hard drive. This slows down the computer and may also prevent legitimate programs from running. Malware can also prevent users from accessing the files in the computer's hardware storage.
