5. Personal Computer (PC):

Personal Computers are also known as microcomputers. It is a general-purpose computer that is designed for personal use. It is comprised of a microprocessor that functions as a central processing unit(CPU) and a memory input and output unit. This type of model of the machine works properly for personal tasks like making assignments watching a movie or in the office for work in the office or other work. Examples include Laptops as well as desktop computers.

Characteristics of Personal Computer (PC):

• There are a small number of software programs that can be used
• This is one of the smaller dimensions.
• It is developed for personal use.

6. Server Computer:

Server Computers are computer systems that merge data and software. Electronic data and programs are stored and shared with server computers. The principle of servers is that they can not solve the same problem as supercomputers but solve several smaller issues. Examples of a server computer are like Wikipedia for instance, when users enter a request for any page, it determines what the user is searching for and forwards the information back to them.

Characteristics of Server Computers:

• Capable of storing and managing large amounts of data.
• Manages multiple devices and users connected to the same network.
• Enhanced security features to protect sensitive data and regulate access.
• Quickly processes user requests and delivers the required data.

7.  Analog Computer:

Analog Computers are specifically built to deal with analog data. Continuous data that change continuously and do not have discrete values are also called analog data. Thus an analog computer can be used when we do not require exact numbers or numbers like temperature, speed, pressure, or pressure. It can directly receive data from the device that measures without first converting it into codes and numbers. It can measure the constant physical changes. It outputs an indication on a scale or dial. For example, a speedometer, a mercury thermometer, etc.

Characteristics of Analog Computers:

• Can directly receive and process data from measuring devices
• Simpler in design compared to digital computers.
• Uses physical quantities rather than numerical codes for processing data.

8. Digital Computer:

Digital computers are designed to perform calculations and logical operations at high speeds. They take data that is raw data as input and then process it using programs that are kept in memory to create the output. It only recognizes binary input of 0 and 1, therefore the input data is converted into zero and one by the computer. Then the program is run by it to create the output or result. Modern computers like desktops, laptops, and phones can be described as digital computers.

Characteristics of Digital Computers:

• Capable of performing complex calculations and logical operations rapidly.
• Utilize stored programs to process data and generate results.
• can be used for a wide range of tasks, from simple calculations to complex simulations.

9. Hybrid Computer:

As the name implies, the word “hybrid” means created by combining two things. In the same way, a hybrid computing device is a blend that combines analog as well as digital computers. Hybrid computers are as fast as analog computers and feature speed and accuracy similar to digital computers. 

Therefore, they can process both discrete and continuous data. It works when it takes analog signals as input, it converts them to digital form before taking care of the input data. It is used in applications that require both analog as well as digital data to be processed. A processor that is utilized in petrol pumps to convert the fuel flow measurements into price and quantity is an illustration of a hybrid computer.
