Process Management
A process is an instance of a program in execution. The operating system (OS) provides essential resources and abstractions for each process, including:
- Logical Flows of Control:
- Single-threaded programs have one flow of control.
- Multi-threaded programs have multiple flows of control.
- Private, Protected Address Space: Each process has its own isolated memory space for security and stability.
- Abstracted Resources: The OS provides a layer of
Common Polymers: Types, Trade Names, and Applications
Phenolic Resins
Phenolic resins are formed by combining phenol (carbolic acid) with formaldehyde. They are known for their electrical insulation properties and are used in power supplies, handles, switches, plugs, housings, and various boxes. Trade names include Bakelite, Durito, and Resiform.
Urea Resins
Urea resins are synthetic materials made from urea and formaldehyde. They are commonly used in electrical equipment (switches, plugs), insulation boards, and kitchen items. Trade names include Pollopas,

Drilling and Plugging
The drilling and plugging method is suitable for repairing cracks that run in reasonably straight lines and are accessible at one end. This involves drilling along the length of the crack and grouting it to form a key using precast concrete or mortar plugs set in bitumen. The bitumen serves to break the bond between the plugs and the hole, preventing the plugs from cracking due to subsequent movement of the opening. For an enhanced seal, a second hole
