Difficult
User face difficulty to use CLI, because that is not familiar with command
Control
Users have a bit control over OS. We can copy several files with one command.
Resources
CLI provide less resources then GUI.
Multitasking
In command line interface, multitasking is possible for user but do not provide efficiency like GUI.
Graphical user interface

In the 1980, today mostly people use graphical user interface. People click any icon instead of typing command. People can use easily. It can provide effective feedback. The example of GUI is window. In GUI the user interact with devices instead of typing command.
Ease
Mostly all beginners use GUI because it is faster than CLI.
Control
GUI provide lot of access to files, and software feature
Resources
GUI require resources such as loading, icon font video
Multitasking
Windows enable the user to control and perform multiple task at the same time.

Evolution of Hardware Interfaces
First Generation of computer
The first computer was developed in1942, the first generation computers used vacuum tube everyone cannot purchase these computers because the material is expensive.
• User given input through punch card
• Magnetic tape is a storage media
Disadvantage
• The computers of this generation require air condition room because the vacuum tubes get hot and burn out.
• Maintenance problem

These are the example of first generation computers is are
• ENIAC
• UNIVAC-1
Second generation of computer

Second generation computers are introduced in 1947, . These are used in second generation computer.
The big change is replacing vacuum tube in transistor. These computers less expensive and smaller then first generation. Second generation had a high processing speed these computer use symbolic language and high level language. Such as COBOL, FORTRAN. Example of
• IBM 7094
• IBM 1400
Disadvantage
• The problem in these computers is maintenance.
Third generation of computer
Third generation was made by JAK in 1958.First computer of this generation used in 1961. IC used in these computers. Types of these computers UNIVAC1108, IBM370
• These are smaller in size
• High level language use in this computer
• User given input via disk, tap
• Used for business and storage is magnetic core memory
Advantage
• This generation of computer increased performance
• Reliable and fast computer
Disadvantage
• ICs are worldly-wise

Fourth generation computer
The concept of microprocessor was developed in 1971. Fourth generation computers started with the invention of microprocessors it revolutionized the computer world. New micro processors are less than one square inch. There are few types of Apple, Dell
Advantage
• Main components are integrated circuit.
• Fourth generation computer production is less expensive.
• User given input and output through devices. These are used in digital weight machines
Disadvantage
These computers are not artificial intelligence
Now present computer
These computers are based on artificial intelligence, are still in advanced stage.
Today we use different types
• Laptop , Smartphone , tablet , notebook
• These computers much smaller and handy while traveling
Features
• User given input touch and devices
• These computer are very fast and cheaper
• Silicon chip

Disadvantage
• None
