Penetration test is a method of evaluating the security of a computer system or network by simulating an attack from a malicious source.

• Penetration test involves identifying vulnerabilities in a system or network.

• It includes attempting to exploit these vulnerabilities to determine the potential impact of a real attack.

• The goal of a penetration test is to strengthen the security defenses of the system or network.

• Common ...read more

Waterproofing is a process of making a structure or material resistant to the penetration of water.

• Waterproofing involves applying materials or coatings to prevent water from seeping through surfaces.

• It is commonly used in construction to protect buildings from water damage.

• Examples of waterproofing materials include bituminous coatings, cementitious waterproofing, and liquid membrane systems.

Types of foundation include shallow, deep, and pile foundations.

• Shallow foundations are used when the soil is strong enough to support the structure's weight, such as spread footings and mat foundations.

• Deep foundations are used when the soil is weak and unable to support the structure's weight, such as pile foundations and drilled piers.

• Pile foundations are deep foundations that consist of long, slender columns driven...read more

M25 and M20 are concrete grades with specific mix ratios for strength and durability in construction.

• M20 concrete mix ratio is 1:1.5:3 (Cement: Sand: Aggregate).

• M25 concrete mix ratio is 1:1:2 (Cement: Sand: Aggregate).

• M20 is suitable for moderate strength applications like residential buildings.

• M25 is used for structures requiring higher strength, such as beams and columns.

• The numbers (20 and 25) represent the charact...read more

The steel weight calculation formula helps determine the weight of steel based on its dimensions and density.

• The formula to calculate the weight of steel is: Weight (kg) = Volume (m³) × Density (kg/m³).

• For example, for a steel bar with a diameter of 10 mm and a length of 1 m, the volume is π × (0.005 m)² × 1 m.

• Density of steel is typically around 7850 kg/m³, so using the volume calculated, you can find the weight.

• For a...read more
