 Computer Memory

When a computer processes any operation, it needs to store the data and instructions temporarily.The computer stores this data and information in the memory. The memory chips on the motherboard in the computer CPU perform this function. This memory which is stored temporarily is called Primary Storage.



A BYTE is a basic storage unit of a memory. The data and instructions all exist as Bytes. 1 BYTE consist of 8 BITS. A Bit is the smallest unit of information a computer can possess. For example: 

11001100 = 1 Byte

00001000 = 1 Byte

011000001010101011111111 = 3 Byte

1010111100000011100001110001111010101111 = 5 Byte

One Byte can store one character of information. A character can be a numbe, an alphabet or a symbol. For example '5', 'U', '+' each of the 3 characters are made of 1byte  each. Any name like, say [MANOJ KUMAR] consists of 11 characters (10 letters and 1 space) and so occupies memory space of 11 bytes inside a computer.

Since computers need to store a large amount of information, various unis have been assigned to measure memory.

1 nipple= 4bit

8 bites = 1bytes

KiloByte(KB): 1 Kilobyte = 1024 Bytes

MegaByte(MB): 1 Megabyte = 1024 Kilobytes = 1048576 Bytes

GigaByte(GB): 1 Gigabyte = 1024 Megabytes = 1048576 Kilobytes = 1073741824 Bytes

TeraByte(TB): 1 Terabyte = 1024 Gigabytes = 1048576 Megabytes = 1073741824 Kilobytes = 1099511627776 Bytes!!!.

  Understanding How Hydraulics Work Hydraulics is a branch of engineering and physics that uses the mechanical properties of fluids, typically liquids, to perform work. From heavy machinery like excavators to car brakes, hydraulics is the driving force behind numerous industrial, automotive, and everyday systems. The principle that governs hydraulics is simple yet powerful: liquids are incompressible and can transmit force efficiently in a confined space. In this essay, we will delve into the fundamental principles, components, and applications of hydraulics, highlighting the science behind their operation and their significance in modern engineering. Fundamental Principles of Hydraulics The operation of hydraulics is based on two fundamental concepts: Pascal's Law and the properties of fluids. 1. Pascal's Law Discovered by Blaise Pascal, this law states that pressure exerted on a confined fluid is transmitted undiminished in all directions throughout the fluid . This principle...

How does Refrigerator cool?

A refrigerator operates on the principles of thermodynamics, utilizing a combination of components and processes to maintain a cool temperature inside. The fundamental concept behind refrigeration is the removal of heat from the interior of the refrigerator, thus lowering the temperature and preserving the contents. Let's delve into the intricate workings of a refrigerator, exploring its key components and the science behind its cooling mechanism. 1. Refrigeration Cycle: It the heart of every refrigerator is the refrigeration cycle, a continuous process that involves the circulation of a refrigerant through various components. The cycle begins with the compression of the refrigerant, typically a gas, in the compressor unit of the refrigerator. 2. Compressor: The compressor plays a pivotal role in the refrigeration cycle. It pressurizes the low-pressure, low-temperature gas refrigerant, causing it to become a high-pressure, high-temperature gas. T...

  HTML Overview HTML ( HyperText Markup Language ) is the standard language used to create webpages. It structures the content by defining elements like text, images, links, and forms. HTML is made up of tags , which are enclosed in angle brackets ( < . > ) Most tags come in pairs: an opening tag ( <tag> ) and a closing tag ( </tag> ) , with content placed between the two. Some tags, however, are self-closing. Basic Structure of an HTML Document html < !DOCTYPE html > < html lang = "en" > < head > < meta charset = "UTF-8" > < meta name = "viewport" content = "width=device-width, initial-scale=1.0" > < title > Document Title </ title > </ head > < body > < h1 > Hello, World! </ h1 > < p > This is a paragraph. </ p > </ body > </ html > <!DOCTYPE html> : Declares the document type and versi...
