1. KADA SU SE POJAVILI PRVI MIKROKONTROLERI I KO SU BILI PROIZVODJACI Prvi mikrokontroleri su se pojavili 70-ih godina dvadesetog veka a proizvodile su ih kompanije Intel i Motorola. Nastali su kako rezultat razvoja računarskih arhitektura i tehnologije izrade integrisanih kola 2. KOJA JE RAZLIKA IZMEDJU MIKROPROCESORA I MIKROKONTROLERA Mikroprocesori su pre svega optimizovani za brzinu i performanse kod računarskih programa, dok su mikrokontroleri otimizovani u pravcu integracije većeg broja

Describe Cohen Sutherland algorithm for line clipping with suitable example. Give its limitations.
Cohen–Sutherland Line Clipping Algorithm
Definition:
The Cohen–Sutherland algorithm is a line clipping method used to clip a line segment against a rectangular clipping window. It divides the area around the window into regions and assigns a 4-bit region code (Outcode) to each endpoint of the line.
Assign 4-bit codes to each endpoint — each bit represents a position

Cost refers to the total monetary value of resources expended to produce a good or provide a service. It is the financial sacrifice made to achieve a specific objective. For example, the cost of manufacturing a product includes the expenses for materials, the wages paid to workers, and other expenditures incurred during its creation.
Costing is the practical process and technique used to determine the total cost of a product, service, or business operation. It is the systematic procedure
Attention is the most valuable resource we have, though it is weightless, invisible, and unmeasurable by any instrument. Like energy, it cannot be created from nothing; it must be drawn from somewhere. Every choice to focus on one thing is a quiet act of neglect toward everything else. Modern life has made this trade-off more violent than ever. We live inside an ecosystem designed to fracture concentration into packets of dopamine. Notifications, feeds, and algorithms are...
