  • 3. Activity Experience (5 minutes)Introduce yourselves briefly by sharing the type of farm activities that you are engaged inand whether you have used a computer before.Basic Computer Hardware and Software SystemsMany farmers shun using ICT because they believe it is complicated and overly expensivebut in reality, there are many benefits to be derived from using such systems. Let usinvestigate..What is a computer?A computer is a tool for processing data. Processed data is called information. Thus acomputer is a tool that enables us to input agricultural data such as farm records orfinancial records and it outputs relevant information such as yield information or profits tosupport us in our business and daily lives.A computer can also be viewed as an automatic electronic device, that process and storesdata. Figure 1 shows the components that make up a typical personal computer (PC) ordesktop system.. Figure1: A desktop computer or PCWhat is a System? Page 136A system is a set of interrelated functional parts working together for a commongoal/purpose.. Module 4: ICT in Support of Farming Lesson 1:Introduction to Computers
  • 4. What is a Computer System? Yes, because it consists of functional parts that work together to produce vital information. In simple terms we could say that it consists of only three components, hardware, software and org-ware. Let us look at hardware first. Below is a diagram that shows you some of the most common hardware components.. Figure 2: examples of computer equipment Computer hardware consists of input devices, output devices and a central processing unit (CPU) .

  • 5. Software SystemsThese are computer programs that instruct the computer how and when to perform certainfunctions or achieve a desired result. The Software System consists mainly of SystemSoftware and Application Software..Software SystemsThese are the programs that control and coordinate the operations of a computer. Theyconsist of operating systems like Windows XP, Vista or Windows 7, Linux, AppleMacintosh etc. and include utility programs like an antivirus program Figure 4: Illustration of how operating systems control and coordinate other computer resources Page 138 Module 4: ICT in Support of Farming Lesson 1:Introduction to Computers
  • 6. Application SoftwareThese are programs designed to accomplish a given task. Examples include wordprocessors for producing documents like letters, memos and reports, spreadsheets fortabulation (an automatic worksheet), and database programs for advanced data storageand analysis.
