an operating system controls the allocation of resources and services such as memory, processors, devices and information. They'll give your presentations a professional, memorable appearance - the kind of sophisticated look that today's audiences expect. Activity Procedure 1. While the term computer can apply to almost any device that has a microprocessor in it, most people think of a computer as a device that receives input from the user through a mouse or keyboard, processes it in some fashion and displays the result on a screen. Electronic Analogue Computer: In this type of analogue computer, electrical signals flow through capacitors and resistors to simulate physical phenomena. common types of printers are ink jet (left), which are typically used in homes and small businesses, and laser printers (right), which are used in schools and large businesses. LAN is the smallest network compared to other two networks. Since hair evidence ls generally small in nature, care should be taken to protect evidence from loss or contamination.

CBSE Class 2 Computer Science Worksheet for students has been used by teachers & students to develop logical, … The fastest and most powerful type of computer Supercomputers are very expensive and are employed for specialized applications that require immense amounts of mathematical calculations. I/P Devices. Computer contains wires, transistors, circuits, hardware parts and etc. USB 1.0, 2.0, and 3.0 – These are the versions of USB, and every later version of the USB simply supports a better data transfer rate. 2. picking, scraping, combing, or vacuuming. 4. Every computer system requires at least one chassis to house the circuit boards and wiring. LAN is operated within a limited physical area such as at home, school, a single building or several buildings. On the basis of Size: Type of Computer. 3. 2. 5. 2) Digital Computer 2. Actual personal computers can be generally classified by size and chassis / case. An operating system (os) is an intermediary between users and computer hardware. The voltage of the electrical signal generates the appropriate displays. CBSE Worksheets for Class 2 Computer Science: One of the best teaching strategies employed in most classrooms today is Worksheets. General computers made with following types of components in hardware. As a class, discuss the material presented in the worksheet. Computer designs with both software and hardware. A hybrid computer system setup offers a cost effective method of performing complex simulations. The chassis or case is the metal frame that serves as the structural support for electronic components. 2. Here, the mechanical interaction of components does not take place. Super Computer .
