what is solidworks ? SolidWorks is a popular 3D computer-aided design (CAD) software that is used for creating and designing complex models and assemblies in mechanical engineering, product design, and other industries. It is developed by Dassault Systèmes, a French software company that also owns other popular software such as CATIA and SIMULIA. SolidWorks provides a range of tools and features for creating 3D models, such as sketching, surface modeling, solid modeling, sheet metal design, and assembly modeling. It allows users to simulate and analyze the performance of their designs before manufacturing, including motion analysis, finite element analysis (FEA), and computational fluid dynamics (CFD). It also supports collaboration and sharing of designs with other users through various formats such as STEP, IGES, and STL. SolidWorks is known for its user-friendly interface and intuitive design, which makes it easy for beginners to learn and use. It is widely used in industries such a...
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 to refreshed , unlike DRAM .
SRAM is faster than DRAM.
Both types of RAM are volatile , meaning that they lose their contents which the power turn off.
1MB = 1024 KB
1GB = 1024 MB
1TB =1024 GB
1PB = 1024 TB
KB - kilobytes
MB - Megabytes
GB - Gigabytes
TB - Terabytes
PB - Petabytes
Why 1 MB = 1024 KB ,not 1000 KB ?
Answer , computers are based on the binary system.that means hard devices and memory are measured in power of 2 .
What is RAM Latency ?
A delay in transmitting data between a computer's RAM and it's processor .
Since RAM is not necessary fast compoted to the processor .
