1 What is the role of computers in business and in science and engineering? Explain.
Answer: Role of computers in business
In an age of booming technology, running a business without computers is like trying to breathe without lungs. Like it or not, technology has become an integral part of the way business is done.
Retail and wholesale business have increasingly come to rely on computers’ advanced ability to keep track of inventory and assist in ordering more when stocks get low. In fact, one of the central approaches to the success of retail giant WalMart was real time ordering in which WalMart’s computer systems place orders for goods as they are needed. This allowed them not to carry too much or too little of any particular item as well as to save on the manpower required to manage much of the supply chain.
A business not involved in electronic communications — particularly email — closes off one of the largest communication channels today. Customers,
Q.2 Differentiate between primary memory and secondary memory.
–
Primary memory:-
- Primary storage, also known as main storage or memory, is the area in a computer in which data is stored for quick access by the computer’s processor. The terms random access memory (RAM) and memory are often as synonyms for primary or main storage. Primary storage is volatile and can be contrasted with non-volatile secondary storage, also known as auxiliary storage. The terms main storage and auxiliary storage originated in the days of the mainframe computer to distinguish the more immediately accessible data storage from data stored on punch cards that required input/output (I/O) operations. In the days when mainframe data storage contained ferrite cores, the term core storage was often used in
Q.3 what is cache memory? Explain the importance of cache computer memory.
Answer: – cache memory:- A CPU cache is a cache used by the central processing unit (CPU) of a computer to reduce the average time to access data from the main memory. The cache is a smaller, faster memory which stores copies of the data from frequently used main memory locations. Most CPUs have different independent caches, including instruction and data caches, where the data cache is usually organized as a hierarchy of more cache levels.
Overview:- When the processor needs to read from or write to a location in main memory, it first checks whether a copy of that data is in the cache. If so, th
Q.4 Write the steps to insert one or more columns and one or more cells in MS Excel.
Answer: – steps to insert one or more columns and one or more cells in MS Excel:-
Step 1:-
Insert Cells into an Excel Worksheet
Having to insert extra cells to an Excel worksheet from time to time is a common practice: data gets forgotten and must be added, space must be made for new data, or existing data gets moved about when the sheet is reorganized.
5 What do you mean by animations? Explain web animation.
Answer: Animation is the process of creating motion and shape change[Note 1] illusion by means of the rapid display of a sequence of static images that minimally differ from each other. The illusion—as in motion pictures in general—is thought to rely on the phi phenomenon.
Animations can be recorded on either analogue media, such as a flip book, motion picture film, video tape, or on digital media, including formats such as animated GIF, Flash animation or digital video. To display it, a digital camera, computer, or projector are used.
Uses of Animation on a Web Page
Q.6 What is Internet? What is the use of it Internet in the modern world.
Answer: – Internet:- The Internet is a global system of interconnected computer networks that use the standard Internet protocol suite (TCP/IP) to link several billion devices worldwide. It is an international network of networks that consists of millions of private, public, academic, business, and government packet switched networks, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries an extensive range of information resources and services, such as the inter-linked hypertext documents and applications
