Cache Memory

cache memory diagram

 

Hello Readers,

Today I will discuss Cache Memory and its importance.

Importance

• It Is Small faster Memory which stores copies of the data from the most frequently used by main memory location

• Actually it is placed between Microprocessor & RAM.

• It stored the address of memory location by which the microprocessor doesn’t need to cache its address again and again. Once Cache Memory Cached That Address then RAM and Microprocessor Directly Operate it rapidly.

Uses

• Due to cache memory, average latency memory is increases

• and also It gives faster access to currently needed data

• It also reduces the average time of accessing memory for RAM and Microprocessor

• It is a special type of memory which is used to fast access to microprocessor

Types:

1. Level 1 (L1) cache or Primary Cache – L1 is the primary type cache memory. The Size of the L1 cache very small compared to others that are between 2 KB to 64 KB.

2. Level 2 (L2) cache or Secondary Cache – L2 is a secondary type cache memory. The Size of the L2 cache is more than L1 that is between 256 KB to 512 KB. It resides on the computer microprocessor.

 
3. Level 3 (L3) cache or Main Memory – The L3 cache is larger in size but also slower in speed than L1 and L2, it’s size ranges between 1 MB to 8 MB.

 

If you have any questions regarding this article. Then please do let me know. I would be happy to help you. 

Thanks For reading

Automation - Update Naukri Profile Using Selenium

Recently one of my friend came to me with a problem. He is looking out for new job but he feels quite boring to update  his profile on daily basis. As some people says updating profile in the morning gives you more calls as it keeps the newly updated profile on top (Although i don’t know whether naukri works this way or not 😀 ). As i was more interested to solve his problem.  After listening his problem i came to solution that instead of updating it manually lets make this job automatic. And it is quite interesting how we can automate our daily boring task with automation. Another day i came with the solution . And the solution was to make it automatic using selenium (Those who are not aware about selenium do check this link) In short, Selenium is a Testing automation Framework. And it is for automating web applications for testing purposes, but is certainly not limited to just that. Boring web-based administration tasks can (and should) also be automated as well....

OpenCV - Drawing a Circle with python

In this tutorial, I will show you how to draw a circle in OpenCV. OpenCV comes with lots of built-in functions that make our life easier especially when we are working on image processing .  And there is a function called circle in OpenCV which is used to draw a circle. This function takes following parameters: 1. Image : Takes an image object 2. Center : Center point coordinates 3. Radius : Radius of the circle 4. Color : Takes color in BGR format 5. Thickness : By default set to 1 (optional) 6. Line Type : By default set to 8-connected.It can also be  LINE_AA  or  4-connected  (Optional) 7. Shift:  Shifts fractional bits in the point coordinates of center and radius (Optional) Especially when we are creating closed shapes. Thickness plays an important role. Here if the negative thickness is passed in this function or any other function which creates a closed shape(rectangle, polygon, etc). Then it creates a filled shape (filled with color). Negative Thickness Filled Circle Positive ...

Basic BIOS password crack

This is a password hack but it clears the BIOS such that the next time you start the PC, the CMOS does not ask for any password. Now if you are able to bring the DOS prompt up, then you will be able to change the BIOS setting to the default. To clear the CMOS do the following: Get DOS prompt and type: DEBUG hit enter -o 70 2e hit enter -o 71 ff hit enter -q hit enter exit hit enter Restart the computer
