it is a multidisciplinary field of study focusing on the design of computer technology and, in particular, the interaction between humans (the users) and computers. While initially concerned with computers, HCI has since expanded to cover almost all forms of information technology design.

human-computer interaction

is quite a complex and abstract system.

human brain

A human brain has a capability to

encode,retain, and store information

it is where the brain store all information

memory

these are the living cells that used as the storage unit

neurons

these are made up of synapses

neurons

they are responsible for transmitting the electric neural impulses from one neuron to another.

synapses

it is an electronic device that can perform a task based on instructions of the user.

computer

computer is built up of several electronic components like

transistors, logic gates, capacitors, diodes

The main things that comprise a computer are

motherboard, cpu, gpu, ram, hard disk drives

it is a circuit board through which all the different components of a computer communications and it keeps everything together.

motherboard

Computers respond to commands given to them in the form of numbers, alphabets, images etc. through input units or devices like – keyboard, joystick etc. These inputs are then processed and converted to computer language and then the response is the output in the language that we understand or the one we have programmed the computer with.

input unit

The result of the command we provide the computer with through the input device is called the output. The most used is the monitor since we give commands using the keyboard and after the processing, the result or outcome is displayed on the monitor Central Processing Unit (CPU)

output units

it is called the brain of the computer since no action can take place without its permission and execution as the main processing uni

central processing unit

write components of the cpu

memory unit, control unit, arithmetic and logical unit, graphics processing unit, random access memory, storage unit

The information entered through the input devices is saved in the memory of the BLANK

central processing unit

This unit controls the functioning component of the computer. It collects the data entered, leads it on for processing after the processing is done, receives the output and provides it to the user.

control unit

This unit does mathematical calculations, arithmetic operations, comparison of data and decision making. It has circuits that are built for addition, subtraction, multiplication, division and other calculations.

arithmetic and logical unit

it helps generate high-end visuals like the ones in video games. Good graphics like these are also helpful for people who have to execute their work through images like 3D modellers and others who use resource-intensive software. It generally communicates directly with the monitor

graphics processing unit

it is the most commonly referred component in a computer. it is also known as the volatile memory since it gets erased every time the computer restarts. It stores the data regarding the programs which are frequently accessed programs and processes. It helps programs to start up and close quickly. It being slower has made it more obsolete these days.

random access memory

these are disks that store data and this data is read by a mechanical arm

hard disk drives

write types of computers

mini computers, micro computers, personal computers, super computers, laptop, tablet
