Types of Computer
On the idea of knowledge handling capabilities, the computer is of 3 types:
Analog pc
Digital pc
Hybrid pc
1) Analog Computer
Analog computers are designed to method analog knowledge. Analog knowledge is continuous knowledge that changes unceasingly and can't have separate values. {we can|we will|we are able to} say that analog computers are used wherever we do not want precise values perpetually like speed, temperature, pressure, and current.
Analog computers directly settle for the info from the instrument while not 1st changing it into numbers and codes. They live the continual changes in the physical amount and usually render output as a reading on a dial or scale. meter and thermometer are samples of analog computers.

Advantages of exploitation analog computers:
- It permits a period of time operations and computation at an equivalent time and continuous illustration of all information among the fad of the analog machine.
- In some applications, it permits activity calculations while not taking the assistance of transducers for changing the inputs or outputs to digital electronic kind and contrariwise.
- The coder will scale the matter for the dynamic vary of the analog computer. It provides insight into the matter and helps perceive the errors and their effects.
Types of Analog computers:
Slide Rules: It's one of the only styles of mechanical analog computers. it absolutely was developed to perform basic mathematical calculations. it's a product of 2 rods. To perform the calculation, the hashed rod is softened to line up with the markings on another rod.
Differential Analysers: It absolutely was developed to perform differential calculations. It performs integration mistreatment wheel-and-disc mechanisms to resolve differential calculations.
Castle Clock: it absolutely was fabricated by Al-Jara. it absolutely was ready to save programming directions. Its height was around eleven feet and it absolutely was supplied with the show of your time, the zodiac, and also the star and satellite orbits. This device conjointly may enable users to line the length of the day as per the present season.
Electronic Analogue Computer: During this style of the electronic computer, electrical signals flow through capacitors and resistors to simulate physical phenomena. Here, the mechanical interaction of parts doesn't happen. The voltage of the electrical signal generates suitable displays.
2) Digital Computer
A digital computer is meant to perform calculations and logical operations at high speed. It accepts the data as input within a variety of digits or binary numbers (0 and 1) and processes it with programs keep in its memory to supply the output. All trendy computers like laptops, desktops as {well as|together with} smartphones that we use reception or workplace square measure digital computers.

Advantages of digital computers:
- It permits you to store an outsized quantity of knowledge and to retrieve it simply whenever you wish it.
- You can simply add new options to digital systems additional simply.
- Different applications will be employed in digital systems simply by dynamical the program while not creating any changes in hardware
- The cost of hardware is a smaller amount thanks to the advancement within the IC technology.
- It offers high speed because the knowledge is processed digitally.
- It is extremely reliable because it uses error correction codes.
- Reproducibility of results is higher because the output isn't tormented by noise, temperature, humidity, and alternative properties of its elements.
3) Hybrid Computer
Hybrid pc has options for each analog and computing machine. it's quick like associate analog computer and has memory and accuracy like digital computers. It will method each continuous and separate information. It accepts analog signals and converts them into digital types before the process. So, it's wide utilized in specialized applications wherever analog and digital information is processed. as an example, a processor is employed in fuel pumps that converts the measurements of fuel flow into amount and value.

Advantages of exploitation hybrid computers:
- Its computing speed is incredibly high thanks to the all-parallel configuration of the analog system.
- It produces precise and fast results that are additional correct and helpful.
- It has the power to unravel and manage huge equations in the time period.
- It helps within the online processing.
On the Basis of Size Computer Types:
1) Super computer
Supercomputers are the largest and quickest computers. they're designed to method large quantity of knowledge. A mainframe will method trillions of directions during a second. it's thousands of interconnected processors.

Characteristics or applications of supercomputers:
It has the flexibility to decode your word to boost protection for security reasons.
It produces wonderful leads to animations.
It is used for virtual testing of nuclear weapons and important medical tests.
It will study and perceive climate patterns and forecast climate. It will run in NOAA's system (National Oceanic and atmospherical Administration) which will execute any kind of straightforward and logical knowledge.
It helps in planning the flight simulators for pilots at the beginner level for his or her coaching.
It helps in extracting helpful data from knowledge storage centers or cloud systems. for example, in insurance firms.
2) Mainframe computer
Mainframe computers are designed to support tons of or thousands of users at the same time. they'll support multiple programs at an equivalent time. It suggests that they'll execute completely different processes at the same time. These options of mainframe computers create them ideal for giant organizations like banking and medium sectors, which require managing and method high volume of knowledge.

Characteristics of Mainframe Computers:
It will method large quantity of knowledge, e.g. innumerable transactions in an exceedingly second within the banking sector.
It has a really long life. It will run swimmingly for up to fifty years when correctly installed.
It provides wonderful performance with giant-scale memory management.
It has the flexibility to share or distribute its employment among different processors and input/output terminals.
There area unit fewer possibilities of error or bugs throughout the process in mainframe computers. If any error happens it will fix it quickly while not poignant the performance.
