ANSWERS:
Q1: What is a peripheral device and how are they connected to a computer?
A1: Peripheral devices are elements or components connected to a computer apart from the system unit. They include devices like printers, scanners, and keyboards. These devices are connected to the CPU using special cables called data interface cables, which carry data, information, and programs to and from the devices.
Q2: How is the find and replace feature used in word processors?
A2: The find and replace feature in word processors is used to search for specific words or phrases within a document and replace them with alternative words or phrases. It allows users to quickly locate and modify text throughout the document, saving time and effort compared to manually editing each occurrence.
Q3: What are three important factors to consider when purchasing a microcomputer?
A3: When purchasing a microcomputer, three important factors to consider are the type of processor, processing speed, and amount of main memory (RAM). Additionally, factors such as storage capacity of the hard disk, cost of the computer, speed of output devices, and the number of users who can access the computer simultaneously should also be taken into account.
Q4: What are two proper sitting postures while using a computer?
A4: Two proper sitting postures while using a computer are adopting a relaxed and straight back position to avoid bending forward or leaning far backwards, and ensuring that the feet are firmly placed flat on the floor. Additionally, the seat should be at a height that allows the eyes to be level with the top of the screen and have a straight backrest to promote upright sitting. It is important that the chair or working surface is at a suitable height, allowing the forearms to be parallel to the floor and the wrists to be straight, and that the seat is positioned at a height relative to the table that enables comfortable use of peripheral devices.
Q5: What is the difference between cold booting and warm booting?
A5: Cold booting occurs when a computer that was originally off is switched on by pressing the power button on the system unit. On the other hand, warm booting happens when a computer that was originally on is forced to restart by pressing the restart button on the system unit or by using a specific key combination like Ctrl+Alt+Del on the keyboard.
