Cache Memory use to improve your experience in computers and Phones. Cache memory faster than ram and SSD, HDD. In this article, I Explain What is Cache Memory in computers, Mobile Phones, Cache Latency, and Type of Cache Memory, etc.

What is Cache Memory in Computer?

Cache Memory is Faster than Ram, ROM but Cache memory size is limited. It is the fastest memory that provides high-speed data access to a computer microprocessor. Cache Memory holds mostly requested or used Information and instructions because When the user needs to use that, it will Immediately Available.

Cache Memory makes copies of the data from frequently used main memory locations. The Cache memory works according to various algorithms, which decide what information it has to store. These algorithms work on the possibility of deciding which data will be most needed.

For example, You read a book on your desk Everyday, Here your books are a program file. you need to highlight some points in your book, which means you need to customize your file. So you need a highlighter, And Highlighter has in your desk drawer, Here the drawer is your cache Memory. Where holds mostly requested or used Information and instructions When the user needs to use that, it will Immediately Available.

Type of Cache Memory:

Mainly Cache Memory is three types

  1. Lavel1(L1)
  2. Lavel2(L2)
  3. Lavel3(L3)
  • Lavel1 Or Primary Cache Memory

L1 is a primary cache memory. This type of cache memory is included in the processer. The size of the Lavel1 cache is very small compared to other cache memory. However, L1memory ranges between 2KB to 64KB, it depending on the computer processor. Instructions required by the CPU are first discovered in the L1 Cache.

  • Lavel2 or Secondary Cache Memory

L2 used as secondary Cache memory. In some processors, L2 may be out of CPU, it’s connected with the high-speed bus. The size of the L2 cache is more capacious than L1 which is between 256KB to 512KB. After searching the instructions in L1 Cache, if it is not found, then the computer microprocessor is searched in the L2 cache Memory.

  • Level 3 or Main cache Memory

The L3 cache is large in size. L3 Memory lives outside of the processor. but it’s connected with the high-speed bus. L3 is slower in speed than L1 and L2. Its size is between 1MB to 8MB. In multi-core processors, each core can have L1 and L2, but all cores share a common L3 cache.

What is Cache Latency?

Cache Latency is part of the process of your data. Sometimes when the computer sends a request for some unstored cache files. That time process is a delay for some time, This delay called Cache Latency.

What is Cache Memory For Mobile Phones?

In the Mobile Phone Cache Memory, Apps sorted some temporary files. the Apps more you use, these apps store your temporary data. for when you use it next time, it will start quickly and enhance your experience. However, you can clear cache memory on the mobile phone, to increase your storage.

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.

Example of Vector Graphics Software with Format:

  1. Adobe Illustrator.
  2. CorelDraw.

Vector Graphics typically saved as EPS, AI, SVG, PDF Format.

Example of Raster graphics Software with Format:

  1. Adobe Photoshop.
  2. Gimp.

Raster Graphics saved as JPG, GIF, PNG, TIF, BMP Format.
