Define the term 'simulation' and explain why simulation is important in education.Computer simulation is the generation of a computer model which emulates/mimics a real world situation.
In education, such models are used to enable the learner have a picture of what happens in a real life setup with regard to the simulated concept. For example, when learning about the blood circulatory system, the computer can present the learner with a virtual model showing how blood flows through the entire body. Discuss the importance of ICT in e-learning.Electronic learning is the effective use of computers to present educational knowledge to a targeted audience. It is a learner centered approach where content is prepared and presented to the learner via the computer.
The content may be stored in an interactive compact disk (CD), a server or a website. The content may also have relevant questions to evaluate the learner's understanding of the content presented. Differentiate between computer aided instruction (CAI) and computer aided learning (CAL).30/11/2022 Differentiate between computer aided instruction (CAI) and computer aided learning (CAL).CAI presents the learner with drills on concepts as a means of enabling them to quickly learn them. CAL, on the other hand, presents educational materials for the learner to read and answer a few questions at the end of each topic to test his/her understanding.
Identify four types of computer based learning. Computer aided instruction (CAI)
Highlight three advantages of computerised reservation systems.
Using relevant examples, discuss computer based reservation systems.A computer based reservation system is an automated system used to store information about customer booking and to schedule the use of resources in an organised sequential manner to avoid double booking or underbooking. Examples of such systems include airline and hotel reservation systems.
State four advantages of using EPOS systems in retail stores.
Dani, a customer in one of the local supermarkets, noticed that when the cashier passed a wand over some straight lines printed on the side of an item, the description and price of the item appeared on the screen. Explain this observation.The products in the store are labelled using bar codes. The bar code gives each stock item a unique identity. The bar code reader (wand) interprets the bar code into the product unique identification number and uses it to search and retrieve the product information including its price from the database in the look up files.
The EPOS terminal then computes the bill totals for the customer to pay and automatically updates the stock control files. Identify the main components that make up an electronic point of sale (EPOS) terminal.
Highlight the advantages of computerised inventory control systems.
State three advantages and two disadvantages of using automated teller machines.Advantages
Disadvantages
Define the term 'automated teller machine (ATM)'.An automated teller machine is a computerised device that enables clients of a financial institution to perform basic financial transactions like cash withdrawal, checking account balance and statements without the need for a bank teller.
Using an example, describe how money is transmitted using electronic funds transfer (EFT).30/11/2022 Using an example, describe how money is transmitted using electronic funds transfer (EFT).Electronic funds transfer is the use, movement or exchange of money digitally from one entity to another. An EFT system transfers money from one account to another electronically either within the same or
different financial institutions. Examples of EFT systems in Kenya include Visa electron, credit card, debit card, Mpesa, M-Kesho, Zap, yu Cash, Orange Money, PayPal, MasterCard, among others. Explain the importance of financial systems in budgeting, Counting, banking and auditing.30/11/2022 Explain the importance of financial systems in budgeting, Counting, banking and auditing.Computer based budgeting systems automate some aspects of financial planning and provide relevant information to the budget preparation personnel in an organisation.
Such systems not only provide historical data but also combine many variables together like inflation, future growth and current constraints that enable planners to prepare well balanced budgets. Accounting is the process of capturing data on how money has been spent and preparing relevant reports. Computer based financial systems are highly suited to perform repetitive tasks like recording transactions, tracking expenditure, enforcing controls and generating accounting reports. Computerised banking systems provide connectivity within. banks. This allows customers to access their accounts from various branches that are in different geographical locations and from automated teller machines. Such banking systems are also able to provide e-banking and m-banking services. Good computerised financial systems provide clear audit trails that are used to track transactions and the flow of money. State four types of financial systems that can be automated using ICT.
