Analog Computers vs. Digital Computers
Analog Computers vs. Digital Computers

There are two types of computers which are known as Analog and Digital Computers. Both these types of machines have their own uses and misuses, but digital computers have taken over analog computers. Analog computers were used a few years ago in abundance, but now their number has decreased thanks to the emergence of Digital computers.

Their differences will be discussed in detail in this article. Both these types of networks are used to transmit information with the help of electrical signal but differ in the way the information is transferred. In Analog computers, the data is forwarded with the support of continuous signals while in digital computers the data is transmitted with the aid of discrete signals which are usually in the form of binary numbers.

The difference can be further explained that Analog computers are less accurate as compared to digital computers. Results that are obtained by Analog computers can have some percentage of error while digital computer results can be up to 100% accurate. Analog computers are used for quantities for which the exact values are not always necessary such as temperature and speed. While Digital computers are used for numbers that require exact values, for example, the calculations which are carried out while constructing a bridge and other operations.

The best example of the analog device will be oscilloscope which is still used by engineers for taking measurements. While the best case of Digital devices will be a pedometer which gives the exact number of steps. Analog computers are slower in speed and are less reliable whereas Digital computers are fast speed devices that can be relied upon. Digital computers are being used all over the world while Analog computers have been restricted to specific fields such as medical and engineering. A further explanation of both these types of the PC is given in the paragraphs below.

Basis Analog Computer Digital Computer
Definition A computer that uses the continuous signal for its operation is called an Analog computer. A computer that uses the discontinuous signal for its operation is called a Digital computer.
Usage Vastly used in different companies and other places. Were mostly employed in the past and currently are only used for experimentation purposes.
Speed Are slower in speed because of their mechanism. Fast
Reliability Less reliable when it comes to obtaining values. More reliable in calculations.

What are Analog Computers?

Analog computers can be a vast field to define. In simple words, a computer that uses the continuous signal for its operation is called an Analog computer. Because of this type of indicator, they are able to receive input and produce output regularly, and this helps in solving complicated processes. However strong the signal may be and even if it is in the form of electrical or mechanical, analog computers are able to deal with it. The emphasis in this type of computer is on obtaining a solution, however, error-prone it may be. Analog computers started way back in the 19th century and have advanced over the years. Before the origin of digital computers, they were considered the best forms of devices. An example of the analog computer will be a mercury thermometer which calculates the temperature of the human body and then displays it as a range of mercury. Because it has noise in its system that affects the results as well while storage process in analog devices is complicated as they may hold values but that is only possible for a certain amount of time.

Analog Computer

What are Digital Computers?

Digital computers are defined as devices that use the discrete signal for their processes which are in the binary form. In Digital computers, the input is coded in the form of zeroes and ones to get a more accurate result. An example of a digital computer will be a calculator in which all the coding is already done, and you get a correct result which is not possible in the case of analog devices. This is also because of the reason that e is minimum noise in the system because the electrical noise coming is in the form of an analog signal. Calculations, in this case, take less time because all the coding is already done and the results which are displaced can be as accurate as possible. Digital devices have taken over the analog ones in recent times because of their Digital Computereffectiveness. It is more reliable, has greater space and can store data for a long time although its cost is higher. The factor that gives it more edge is that there are no observatory errors since all the calculations are done by the computer and values are displayed correctly.

Key Differences between Analog Computers and Digital Computers

The Key Differences between Analog Computers and Digital Computers bet Analog Computers vs. Digital Computers are described below:

  1. Digital computers work on signals which are not continuous while Analog computers work on signals which are continuous.

Conclusion

In the end, the article has explained both the terms with equal emphasis and it can be seen that there is very little difference between the two, which in simple words are already considered synonyms of each other and therefore, a clearer understanding should develop.

Dicot Stem vs Monocot Stem

Dicot Stem vs. Monocot Stem
Dicot Stem vs. Monocot Stem

As we know that plants are mainly divided into two types; flowering plants and non-flowering plants (angiosperms or gymnosperms). It should be kept mentioned that around 80% of all the existing green plants are flowering plants. These flowering plants are further divided into monocots and dicots. The monocot is the plant that has only one cotyledon in the embryo, whereas dicot is the plant that has two cotyledons in the embryo. Monocots and dicots differ from each other in four structures: leaves, stems, roots and flowers. Here we’ll be differentiating it between the stem of the monocot and dicot plant.

The main difference between stems of both the plants is due to the arrangement of the vascular bundle. In monocots stem, the vascular bundles are scattered across the stem without any definite arrangement. On the other hand, in dicots stem, the vascular bundles are arranged in the form of one or two broken rings, following that they have a definite shape.

Cortex & SteleThe vascular system in dicots comprises of the two distinct regions, cortex and stele.The vascular bundles are scattered, they lack the distinct cortex and stele.

What is Dicot Stem?

The dicot stem has single layered epidermis along with the thick cuticle. Mainly the difference in arrangement of the vascular bundles make the difference between them and the monocot stem. As the dicots are more complex as compared to the monocots, they may or may not have the epidermal hairs, which are essential for the insulation, warmth and absorption in plants. Their vascular bundles are arranged in the form of one or two broken rings.

These bundles are definite in shape and size and are smaller in size as compared to the bundles in the monocots.

The hypodermis in the dicot stem is made up of the collenchyma. The main function of the hypodermis is to secrete the chitinous cuticle; it is present in the epidermal layer of cells in plants. In dicot stem, the epidermis is the outermost layer along with the multicellular epidermal stem hairs. The other important regions of the dicot stem are cortex, medullary rays, pericycle and pith. The vascular system in dicots comprises of the two distinct regions cortex and stele, which are absent in the monocot stems. The bundle sheaths, which have the main function to regulate the substances between the parenchyma and vascular tissues, are absent in the dicots.

What is Monocot Stem?

The monocot stem also has the single layered epidermis along with the thick cuticle, although the epidermal hairs are absent in the case. Due to the presence of the lateral branches, circular stems are absent in monocots. As we know that the main difference between dicot and monocot stem is due to the arrangement of the vascular bundles.

Dicot Stem vs Monocot Stem

In monocot stems, the vascular bundles are scattered and are arranged indefinitely in such a way that they are spread throughout the steam area. Although the bundle sheath is present in this case, which surrounds these scattered bundles. The hypodermis in the monocot stem is made up of the sclerenchyma. As the vascular bundles are scattered, they also lack the distinct cortex and stele.

Dicot root vs Monocot Root

Both, Monocot and Dicot roots belong to plants. Monocot and Dicot differ from each other in four structures: leavesstems, roots and flowers. The difference between dicot and monocot root is, dicot root contains xylem in the middle and phloem surrounding it. While, monocot root contains xylem and phloem in another manner, forming a circle. The monocot roots are fibrous while that of dicot is tap roots.

As we all know that plants are mainly divided into two kinds, First, flowering plants and second non-flowering plants (angiosperms or gymnosperms). Moreover, It needs to be kept mentioned that approximately 80% of all of the present green plants are flowering plants. That flowering plants are further divided into monocots and dicots.

The monocot is the plant that has just a single cotyledon in the embryo, whereas dicot is the plant that has two cotyledons from the embryo. Monocots and dicots differ from one another in four structures: leaves, stems, flowers and roots. Here we will discuss the difference between the roots of the monocot and dicot plant. In monocot roots, the pericycle present just produces the roots, whereas, in dicot roots, the pericycle gives rise to roots, cork cambium, and the component of the vascular cambium. The difference between the monocot roots and dicot roots is that the existence of xylem and phloem. moreover, In Monocot, the xylem and phloem are numerous in numbers. while, In dicot, the xylem and phloem are restricted in numbers.

Pericycle In dicot roots, the pericycle gives rise to lateral roots, cork cambium, and the part of the vascular cambium. In monocot roots, the pericycle present only produces the lateral roots.
Pith The Pith is absent in the dicot root. In monocot root, Pith is large and well developed.
Xylem & Phloem In dicot roots, the xylem and phloem are limited in numbers. In monocot roots, the xylem and phloem are numerous in numbers.
Secondary Growth The secondary growth occurs in the dicot root. Absent

What is Dicot Root?

Dicot root has xylem in the form of ‘X’ that is surrounded by phloem. and, it has got tap roots. In a dicot root, the amount of xylem and phloem is continuous. Vessels of xylem are angular or polygonal shape when we cut it in the transverse section. Conjunctive tissue at a dicot root is parenchymatous, which creates vascular cambium. Anatomy of the dicot root can be studied through a cross section (CS).

What is Monocot Root?

Monocot Root has xylem and phloem within an alternating manner. What’s more, it has fibrous roots. Xylem and phloem are presents numerous in number in a monocot root. The vessels of xylem are rounded or oval shape. Conjunctive tissue at a monocot root is mostly sclerenchymatous, at times it could be parenchymatous also.

Key Differences between Dicot Root and Monocot Root

  1. In a dicot root, the number of xylem and phloem is continuous while in a monocot, they are numerous.
  2. Pith is absent or very small at a dicot root, on the other hand, it is Big and well developed at monocot root.
  3. Xylem vessels are curved in a monocot root whereas angular at a dicot root.
  4. The cortex of a Monocot root is broad while that of a dicot root is narrow.
  5. Secondary growth occurs in a dicot root but not in a monocot root.
