Ans. In the IBPS PO Mains 2016 exam, candidates were often asked questions related to computer awareness. Some frequently asked questions include: 1. What is the difference between RAM and ROM? Ans. RAM (Random Access Memory) is a type of computer memory that can be both read and written to, allowing for quick data access. On the other hand, ROM (Read-Only Memory) is a type of memory that is only readable and cannot be modified. It stores permanent instructions that are essential for the computer system to boot up. 2. What is the purpose of a firewall? Ans. A firewall is a network security device that monitors and controls incoming and outgoing network traffic based on predetermined security rules. Its main purpose is to prevent unauthorized access to or from a private network, while still allowing legitimate communication. 3. What is the difference between hardware and software? Ans. Hardware refers to the physical components of a computer system, such as the processor, memory, hard drive, and input/output devices. Software, on the other hand, refers to the programs and data that run on the hardware. It includes the operating system, applications, and other digital instructions that tell the hardware what to do. 4. What is a computer virus? Ans. A computer virus is a malicious software program that replicates itself by modifying other computer programs and inserting its own code. It can spread from one computer to another, causing damage to files, system crashes, and unauthorized access to personal information. Antivirus software is used to detect and remove viruses from a computer system. 5. What is cloud computing? Ans. Cloud computing is a model for delivering computing services over the internet. It allows users to access a shared pool of computing resources, such as servers, storage, and applications, on-demand and over a network. This eliminates the need for users to have their own physical infrastructure and enables flexible and scalable computing resources.
