Six phases/security concerns
Recruitment: The organization checks the applicant’s qualifications, references, and background before hiring. The security concern is reducing insider threats and hiring trustworthy employees.
Onboarding: The employee is officially added to company systems such as payroll and benefits. The security concern is making sure organizational policies and agreements are properly completed.
User provisioning: The employee receives accounts, devices, badges, and system access
A pro forma invoice is a sales document that is issued by the seller, or exporter, before the goods are delivered. It has no fiscal value and the buyer isn't required to pay the amount listed. It is only used as a quotation which the buyer needs for a customs declaration in international shipping or to obtain an import licence - a governmental document that allows the importer to bring the goods into their country. A commercial invoice is a legal document issued by the seller after the goods have

Ethereum is a decentralized, open-source blockchain platform used for executing smart contracts and developing decentralized applications (DApps). It was proposed by Vitalik Buterin in 2013. Ethereum extends blockchain functionality beyond cryptocurrency by providing a programmable platform. Architecture of Ethereum 1. Blockchain Layer: Ethereum maintains a distributed ledger where all transactions and smart contract data are stored in blocks connected cryptographically. Every node maintains a copy

Heat exchange and networking 1. Heat exchanger is a device used to transfer heat from one fluid to another without direct mixing of fluids. 2. In a heat exchanger, hot fluid loses heat while cold fluid gains heat. 3. Heat exchangers are widely used in chemical, petroleum, food and power industries. 4. Common types of heat exchangers are shell and tube, double pipe and plate heat exchangers. 5. Heat exchangers help in heating, cooling, condensation and evaporation processes. 6. Heat exchangers improve

Q.1&2. Brief about the physical deterioration of concrete. Ans:- 1)Physical deterioration of concrete refers to the damage or reduction in strength of concrete due to physical actions such as temperature changes, abrasion, erosion, and moisture variation. It affects the durability and service life of structures.2)Freeze-thaw action is one of the major causes of deterioration in cold regions. Water inside concrete pores freezes and expands, causing cracks and surface scaling.3)Abrasion
MULTITASKING: Performance decreases when doing multiple tasks simultaneously. Practice can improve but doesn't eliminate costs. Task switching has costs (time to reconfigure mental set). Multiple demand system: network of brain regions activated during diverse cognitive tasks. FEATURE INTEGRATION THEORY:Early processing: features (color, shape) detected automatically in parallel. Later processing: features must be bound together by attention (serial). Explains binding problem - how brain combines
