Computer Science Questions and Answers

Cold booting is when you start a computer from a powered-down, or off, state. This is often referred to as a system restart or a system reset. Warm booting, on the other hand, is restarting the computer while it's powered on. Rebooting and soft booting are general terms for restarting a computer and can refer to either cold or warm booting

An OR gate is a digital logic gate that implements logical disjunction - it behaves according to the truth table to the right. A HIGH output (1) results if one or more of the inputs to the gate is HIGH (1). If neither input is high, a LOW output (0) results. In another sense, the function of OR effectively finds the maximum between two binary digits, just as the complementary AND function finds the minimum

A peer-to-peer (P2P) network is a decentralized network where each computer (peer) acts as both a client and a server. This means that there are no dedicated servers and no hierarchy among the computers. However, P2P networks are generally not known for having a strong security system. This is because each peer has equal access to the resources, which can lead to potential security risks

In the CRUD acronym, R stands for 'Read'. CRUD stands for Create, Read, Update, and Delete. These are the four basic functions of persistent storage in databases

The Control Unit of the Central Processing Unit (CPU) coordinates other units and manages the computer resources. It directs the operation of the processor, and interacts with the other hardware components in the system to carry out the instructions of a program. It is responsible for fetching, decoding, and executing instructions from the memory unit and performing arithmetic and logical operations
