Spread the love

All around us, we see different kinds of computers. Like Desktop, Laptop, Server Computer, etc. In this article, i Explain  Classifications of computers by type and size.

The computer can be classified into two categories:

  • According to Type

  • According to size

Classification according to Type


  • Analog Computers

In this Classification of computers by type and size, These Computers recognize data as continuous measurement of a physical property. Their output is usually in the form of readings on dials or graphs. Voltage, pressure, speed, and temperature are some physical properties that can be measured in this way.

Analog Computers

 

Example:-

  1. A Service Station gasoline pump contains an analog processor that connects fuel flow measurements into quantity and price values.
  2. Automobile speed meter, etc.
  • Digital Computers


These are High speed programmable electronic devices that perform mathematical calculations, compare values, and store the results. They recognize data by counting discrete signals representing either a high ‘on’ or low ‘off’ voltage state of electricity. Numbers, alphabets, and special symbols can all reduced to representation by 1s and 0s.

Personal Cpmputer

Example:-

  1. Personal Computer.
  2. The scoreboard directly counts discrete values such as the time left to play and the score of each team.

  • Hybrid Computers


In this Classification of computers, Hybrid computers combine the best features of analog and digital computers. The computer accepts data both from the sensors within the production area and from conventional input/output(I/O)devices.

Using the production data, the computer plans for future manufacturing and distributes existing inventories, activities which require the computer to compute digital data and produce a report for management. So the Hybrid computer is perfectly suited to this application. For instance, the computer can act as a digital computer, processing stored data for management.

Classification of computers by size

Classification according to Size


  • Super Computer

In this Classification of computers by type and size, A supercomputer is generally characterized as being the fastest, most powerful, and most expensive computer. After that, the supercomputer has large memories and high processing speeds: they can process up to billion instructions per second. So They are used for processing very large files and performing large-scale mathematical calculations.

  • Mainframe Computer

In this Classification of computers, A mainframe computer is usually slower, less powerful, and less expensive than a supercomputer. For instance, Mainframes Computer processes a million instructions per second, This kind of computer use in many businesses to update inventory, etc.Classification of computers by size

 

  • Mini Computer

Minicomputer is smaller than mainframe, general-purpose computer and gives computing power without adding the prohibitive expenses associated with large systems. Minicomputer is well adapted for functions such as accounting, word processing, database management, statistical packages for social sciences. Computer-aided design and Numerical Analysis etc.

  • Micro Computer

A Microcomputer is the smallest least expensive of all the computers. The prefix ‘micro’ refers mainly to the physical size of the computer and its circuitry, rather than its capabilities. this kind of computer has the smallest memory and less power is physically smaller and permits fewer peripherals to be attached. An example of a microcomputer is Raspberry PI.Classification of computers by size

  • Laptops and notebook

Laptops and notebooks provide mobile computing technology with, In other words, the same power as personal computers The Laptop battery-operated and you can use it any time anywhere. In this type of computer, you can connect with various input and output devices.

Classification of computers by type

  • Hand-Held Computers

Handheld computers s are even smaller than notebooks. Each handheld computer holds more than 1,200 records and provides police officers with timely and sometimes life-saving information.

 

Classification of computers by type

  • Pen-Based Computing

The pen-based computer is one type of computer which uses an electronic touch writing pad. you can use it with an electronic pen or your finger. When the user writes something on the pad, the Pen-based computer gets all the information as digital input and then stored in a file on the computer.

Explain Lookup function in Excel
Spread the love

Lookup is one of the most used full functions in Microsoft Excel. It’s used to categorize under Excel Lookup and reference functions. In this article, I explain What is the Lookup function in Excel | Explain V and H lookup Function

Explain Lookup function in Excel

The LOOKUP Function is categorized under Excel Lookup and reference functions. This section discusses various techniques that you can use to look UP a value in a range of data Excel has three functions(LookUP, V LookUP, H LookUP) designed for this task.

A Look-UP formula essentially returns a value from a table by looking up another related value. A common telephone directory provides a good analogy. If you want to find a person’s telephone number, You first locate the name and then retrieve the corresponding number.

Example of LookUp Function in Excel :

In Worksheet that uses Several look UP formulas. This Worksheet Contains a table of employee data, beginning in row 7. This range name is EmpData. When you enter the last name into cell C2, lookup formulas in D2:G2 retrieve the matching information from the table. If the last name does not appear in column C, the formulas return.

Explain Lookup function in Excel

The following lookup formulas use the Vlookup function:

  • D2 = VLOOKUP (C2, EmpData,2,FALSE)
  • E2 = VLOOKUP (C2, EmpData,3,FALSE)
  • F2 = VLOOKUP (C2, EmpData,4,FALSE)
  • G2 = VLOOKUP (C2, EmpData,5,FALSE)

 

Explain V-Lookup Function in Excel


The VLookup function looks up the value in the first column of the lookup table and returns the corresponding value in a specified table column. So, the lookup table arranges vertically.

The syntax  for the VLookUp Function is: VLOOKUP(lookup_value,table_array,col_index_num,range_lookup)

The VLookup Function’s arguments are as follows:

  • lookup_value: The value is to be in the first column of the lookup table.
  • table_array: The range that contains the lookup table.
  • col_index_num: The column number within the table from which the matching value is in return.
  • range_lookup: Optional. If TRUE or omitted, an approximate match is returned. However, If FALSE, Vlookup will search for an exact match and, if Vlookup can’t find an exact match, the function returns #/NA.

Explain H-Lookup Function in Excel


The HLookup function works just like the VLookup function except that the lookup table is arranged horizontally instead of vertically. The HLookup function looks up the value in the first row of the lookup table and returns the corresponding value in a specified table row.

The syntax  for the HLookUp Function is: HLOOKUP(lookup_value,table_array,row_index_num,range_lookup)

The HLookup function’s arguments are as follows:

  • lookup_value: The value is to be in the first row of the lookup table.
  • table_array: The range that contains the lookup table.
  • row_index_num: The row number within the table from which the matching value is in return.
  • range_lookup: Optional. If TRUE or omitted, an approximate match is returned. However, If FALSE, Vlookup will search for an exact match and, if Vlookup can’t find an exact match, the function returns #/NA.

Graphics help us to see the photo, video, Animation Popularly, and Vector Graphics are sharp and detailed than Raster Graphics. In this article, I Explain the Difference between Vector and Raster graphics with Examples.

What is the difference between Vector and Raster graphics?

Graphics are part of Multimedia. In Digital media like Photo, Video, Animation all these things are made by graphics. Graphics are two types Vector Graphics and Raster Graphics.

Vector Graphics

Raster Graphics

Vector Graphics are composed of paths. Raster graphics are composed of pixels.
Vector Graphics such as a.eps file or Adobe Illustrator file are composed of paths or lines, that are either straight or curved. Raster graphics Such as a .gif .jpeg is arranging of pixels of various colors, which together form an image.
The data file for a Vector image contains the points where the paths and ends how much the path curve, and the colors that either border or fill the paths. Raster graphics, on the other hand, become “blocky” since each pixel increases in size as the image is larger.
Vector Graphics is Capable of detailed editing. Raster graphics are Less detailed but offer precise paths.
