Computer Application: Spreadsheet

Spreadsheet

Alternatively referred to as a worksheet, a spreadsheet is a data file made up of rows and columns that are used to sort data and allow a user to manipulate and arrange data easily, commonly numerical data. What makes a spreadsheet software program most unique is its ability to calculate values using mathematical formulars and the data in the cell. A good example of how a spreadsheet may be used is creating an overview of your bank's balance. Below is a basic example of what a Microsoft  spreadsheet looks like as well as all the major portions of a spreadsheet highlighted.

hello Kids, Today we are discussing on the types of popular application packages that we have; 1. word processor packages 2. spread sheet packages 3. presentation packages 4. desktop publishing packages 5. database management packages 6. banking packages 7. accounting packages 8. entertainment packages 9. education packages 10.web application packages etc 1. Word Processor Packages : A Word Processing package is an application software that allows the user of a computer to; check for spelling errors, import texts and graphics, create tables, insert diagrams and also has macro languages that are useful for complex applications. it is use to type most of how reports, letters, documents, etc. Functions of word processor packages 1. Creating Documents 2. Editing 3. Sharing 4. Comparing 5. web pages Advantages of word processor packages 1. corrections can be made easily to your work 2. you can save the work and come back later to edit it as many time as you can. 3. you can add features such as page borders, colour, page numbers, text layout etc. 4. you can make use of the tools such as spellchecks, grammar checks to improve your work 5. there are large number of different template available for use. 6. you can create import data from database and spreadsheet packages and it is use to create mail merge. Disadvantages 1. you need to have access to a computer installed with a word processor before you can use it 2. it takes time to learn it effectively 3. so times pen and paper are faster 4, it makes people lazy in proof reading their work and to check for grammatically errors. Examples of word processor 1. Open Office 2. Corel WordPerfect 3. Microsoft Word 4. Word Pad 5. Pages 6. Google Docs (word)

Welcome Back,
I will discuss about the Humanware but pay more emphasis on careers in the Computer Field.

The Humanware are the people that uses the computer, they are the end users who uses the computer for productivity in their different fields. The are the computer operators, secretaries, doctors, lawyers, clerks, programmers etc. In fact all the people that computers are involved in one way or the other in the area of their work.

There is an important part of the computer humanware that I want to talk about, the computer  specialists and this will brings us to career in the computer field.

As we learn all these I believe it will help you kids in the choice of your career in future in the IT field.

Welcome back kids,
Today we will be discussing about computer software in details.

A computer software is a collection of instructions that enables an end user to interact with the computer or have the computer perform specific tasks for them. Without software, the computer would be useless. For example, without your Internet browser software you would be unable to browse the Internet or read this page and without a software operating system the browser would not be able to run on your computer.

Software can be purchased at a local retail computer store and online in form of  disks  such as floppy diskette, CD, DVD, or Blu-ray required to install the program onto the computer, manuals, warranty, and other important documentation.

Software can also be downloaded to the computer over the Internet. Once downloaded the setup file can be run to start the installation of the program on your computer.

 

The computer software is divided into two types

1. System software

2. Application software

 

1. System Software

System software is a type of computer program that is designed to run a computer’s hardware and application programs. it is the interface between the hardware and user applications. The operating system  is the best-known example of system software. The OS manages all the other programs in a computer. other examples are utility programs, translators, compliers, etc

2. Application Software
Application software is a program or group of programs designed for end users. it is sometimes called app.  it also allows us to perform specific tasks. Applications for desktop or laptop computers are sometimes called desktop applications, and those for mobile devices are called mobile apps. When you open an application, it runs inside the operating system which is a system software until you close it. Examples of application software are word processors such as MS word, Spread sheet such as  MS Excel, Accounting Packages such as Peachtree etc.

 

Hello kids,
welcome to another lesson of computer for kids by CompuTeach Education Consult.
In the Last lesson, we discuss about the 3 groups of computer which are the hardware, software and humanware.
Today we will be discussing about the Hardware in details.

The computer Hardware is broadly divided into 4 groups;
1. The Input devicess
2. The Output devices
3. The Storage devices
4. The Processing Device

The Input Device

these are the devices or peripheral  (piece of computer hardware equipment) used to provide data and control signals to  a computer. Examples of input devices include keyboard, mouse, scanner, digital camera and joystick.

the output devices

Any peripheral or device that receives or displays output from a computer. An inkjet printer is an a good example of an output device that can make a hard copy of anything on a computer. other are

 monitor

plotter

projector

speaker

the storage devices

also known as storage media, or storage medium, a storage device is a device capable of holding information. There are two storage devices used in computers; a primary storage  device such as computer RAM and a secondary storage  device such as a computer hardware. The secondary storage could be a removable, internal or external storage.

 

processing device 

Processing devices in a computer are responsible for controlling the storage, processing and retrieval of information. The information is processed by the computer processor Central Processing Unit, which performs data calculations, data comparisons, and data copying with the information from the processing devices. The CPU then saves that information to the computer memory RAM.

 

in our next lesson, we will discuss about Software in details

In our last lesson, we discussed about the 3 groups of computer system which were;
- the hardware
- the software
- the humanware

today we will be discussing in details, the hardware, the software, the humanware.

HARDWARE

The hardware is the physical part of the computer we can see, touch and feel.
It is divided into 4 groups;

- Input devices: These are the devices that we use to put in meaningless raw data into the computer. Examples are Keyboard, Mouse, Joystick, Lightpen, digital camera, scanner, microphone,  Track ball etc.

- Output devices: These are devices that we us to bring out meaningful information out of the computer.  examples are monitor, printer, headphone, plotter, projector,  speakers, etc.

- Processing device: This is the device that processes the meaningless raw data into meaningful information. example system unit.

- Storage devices: These are the devices  or medias that store already processed information for future use. examples are hard disk, floppy disk, Optical Disk, Magnetic tapes, etc.

SOFTWARE

Software is the part of computer we can see but cannot not touch nor feel. It is the instructions or programme that run in the system.

The software is broadly divided into 2 groups;

- System Software: These refers to the software that reside permanently within the computer system that activities other software and enable them to run. They provide the infrastructure over which other programs can operate, which means that they manage and control computer hardware so that the application software can perform. It basically makes system to work. examples are operating system, data communication software, device drivers, language translators, utility software etc.

- Application Software: These are programmes developed and packages together for a specific purpose. examples are word processing packages, spread sheet, education package, desktop publishing, database management software, web applications packages, Presentation package etc.

HUMANWARE

Humanware  are the users that operates or use the computer systems. They are found in the offices, our home, schools etc. examples are computer operators, computer programmers, system analysts, network administrators, database administrator etc.

A computer is an electronic machine that accepts meaningless raw data as input, processes it and bring out meaningful information as output.

A computer system comprises of three main parts which are;

1. Hardware - These are the physical part of the computer we can touch and feel example; mouse, keyboard, monitor, system unit, speakers etc.
2. Software - These are the parts we can only see but cannot touch  or feel examples, system software, application software etc.
3. Humanware- These are the users who use the computer examples; computer specialist, doctors, secretaries etc.

Note: in our next lesson, we will be discussing about the main different parts of the computer in details. feel free to add your comments.
