What is a circuit board?
A printed circuit board (PCB) mechanically supports and electrically connects electronic components using conductive tracks, pads, and other features etched from copper sheets laminated onto a non-conductive substrate. A printed circuit board has pre-designed copper tracks on a conducting sheet. The pre-defined tracks reduce the wiring, thereby reducing the faults arising due to loosen connections. One simply needs to place the components on the PCB and solder them.

MOTHERBOARD : known as the mainboard, system board etc is the main printed circuit board found in computers and other systems. It holds and allows communication between many of the crucial electronic components of a system, such as the central processing unit and memory, and provides connectors for other peripherals.
MICROPROCESSOR: is a computer processor that incorporates the functions of a computer’s central processing unit on a single integrated circuit, The microprocessor is a multipurpose,

1.PLASTIC MATERIALS: In general, plastic materials are a normal part of everyday life. They also play important roles in sectors such packaging, telecommunications, transport, construction, medicine, agriculture and information technology. Plastics consist of long chains of molecules, mostly made of the element “carbon”. These chains of macromolecules are called polymers, which is another name for plastics. Polymers are composed of smaller molecules called monomers. 1.1 THE ORIGIN OF PLASTICS:

Exam Cheat Sheet
Memory
Stack & heap:
C programs use the stack for local variables, function parameters and return addresses.
C programs use the heap for explicitly requested dynamically allocated data (with malloc).
In general, data is put on the stack unless we use malloc then its on heap
Malloc & Free:
Used in C as type of manual memory management
Always free malloc! Else lose point
Modern Languages like Java, Erlang etc. use Automatic Memory Management. The system allocates data structures

In Linux, there are a few different partitioning command line tools we can use. One that supports both MBR and GPT partitioning is the parted tool. Parted can be used in two modes. The first is interactive, meaning we’re launched into a separate program, like when we use the less command. The second is command line, meaning you just run commands while still in your shell. We’re going to be using the interactive mode for most of this lesson. Before we do that let’s run a command to show what disks Read More
