What is RAM : Computer Science

What is RAM ? RAM - Random Access Memory RAM is a hardware device that allows information to be stored and retrieved on a computer. Random Access Memory is a form of computer memory that can be read and changed in any order , typically used to store working data and machine code . Usually more than 1 bit of storage is accessed by the same address and RAM devices ofter have multiple data lines and are said to be 8 bit etc devices . Today RAM takes the form of integrated circuit ( IC) chips with MOS ( Metal oxide semiconductor) memory cell . Types of RAM : 1. Static RAM (SRAM) 2. Dynamic RAM (DRAM) RAM is found in server ,PCs , tablets , smartphones , and other devices such as printer . DRAM : DRAM is typically used for the main memory in computer devices . Dynamic indicates that memory must be constantly refreshed or it will lose its content . DRAM - Or SDRAM In general the more RAM a device has the faster it will perform . SRAM : SRAM is said to be static because it doesn't need ...

Engineering Material and Their Properties: Machine Design

Engineering Material and Their Properties: The knowledge of materials and their properties is of great significance for a design engineer. A Design engineer must be familiar with the effects which the manufacturing processes and heat treatment have on the properties of the materials . Classification of Engineering Materials : 1. Metals and their alloys 2. Non - metals Metals may be further classified as - (a) ferrous metals (b) non -ferrous metals Ferrous metals are those which have the iron as their main constituent . Example : cost iron , wrought iron , steel etc. Non - ferrous metals are those which have a metal other than iron as their main constituent. Example : Copper, Aluminium , Broad , Zinc etc. Selection of Materials for Engineering Purpose : The selection of a proper material , for engineering purposes , is one of the most difficult problem for the designer . The following factors should be considered while selecting the material - 1. Availability of the materials 2. S...

What is Core in computer

What is Core in computer ? A Core is a small CPU or processor build into a big CPU or CPU socket. A Core or CPU core is the brain of a CPU. It receives instruction and performs calculations or operations to satisfy those instruction . A CPU can have multiple cores - 1. Two cores - dual core processor 2. Four cores - quad core ,, 3. Six cores - hexa core ,, 4. Eight cores - octa core ,, CPU - Central Processing Unit - also known as processor,Central processor , or microprocessor. Types of CPU: In past, computer processors used numbers to identify the processor and help identify faster processor. For example : Intel 80486(486) processor is faster than 80386(386) processor. Today processor are different architecture 32 bit and 64 bit . Component of CPU : There are two primary component. 1. ALU ( Arithmetic Logic Unit ) 2. CU ( Control Unit ) What is Core i3, i5 , i7 , i9 ? Core i3 : core i3 is a dual - core computer...

Introduction of I.C.Engine

Definition of Engine : An engine is a device which transforms one form of energy into another form . Normally ,most of the engines convert thermal energy into mechanical work and therefore they are called heat engines Definition of Heat Engine: Heat engine is a device which transforms chemical energy of fuel into thermal energy and utilizes this thermal energy to perform useful work. Thus thermal energy is converted to mechanical energy in a heat engine. Heat engines can be classified into two categories : 1. I.C.Engines 2. E.C.Engines I.C. - Internal combustion E.C. - External combustion I.C. or E.C. are of two types : 1. Rotary engines 2. Reciprocating engines External combustion engines are those in which combustion takes place out- side the engine whereas in internal combustion engines combustion take place within the engine. There are two types of engines : 1. Spark ignition (SI) 2. Compression ignition (CI) Engine Components : 1. Cylinder Block 2. Cylinder...

The Solid State Part -1

Chemistry The Solid State The solid state is the solid state of matter in which the constituent particles are closely packed in the lattice and are unable to move. They can only vibrate along their axes. Classification of solids : 1. Crystalline solids 2. Amorphous solids Classification of crystalline solids: 1. Molecular solids 2. Ionic solids 3. Covalent solids 4. Metallic solids X - ray Differation by Crystal: Bragg Equation : Space Lattice and Unit Cell : Space Lattice or crystal lattice or lattice --- Three dimension arrangement Unit Cell : Unit cell is the smallest three dimensional group of lattice point which, when repeated in three dimentions in space, gives the whole lattice of the crystal.
