Section 29 8.5.14
Today we have an ICT exam in the lab..and had discussion for our mid exam
everyone had past in this mid exam except one,44 sound bad for me =( But at least I had improve ..next term add oil bah..
Recall back ...
- Plotter is not an input device.
- System software controls, integrate and manages the individual component of a computer system
- Example of spreadsheet software
* Lotus 1-2-3
* Microsoft Excel
* OpenOffice Cale
* Borland Quattro Pro
- A control unit fetches instruction from the memory and then decodes and executes them.
- In a computer,1 KB is equal to 1024 bytes
- Computer use binary codes to communicate.
- Jean- Maurine-Emile Bardout(1845-1903) created the teleprinter which used the 5-digit Bardout code
- The clock speed unit in a microprocessor is measured in hertz
- A connector is used to join a cable to a device.
- Camcorders and other video equipments use a FireWire Port to transmit data onto a computer
- MIDI port is designed to connect the system unit to a musical instrument
- IrDA port is for wireless devices to transmit infrared light wave signals to a computer
- SCSI port is a special highspeed parallel port used to attach peripheral devices such as disk drives and printers.

Internet relay Chat - IRC
A multiuser chat system, where people meet of "channel" to talk in group, or privately to exchange comments and information about the topics addressed on the site
3G - Third generation
It is the third generation of mobile phones standards and technology. It promises increased bandwidth, up to 384kbps
HSDPA - High Speed Download Packet Access
A new protocol for the mobile telephone data transmission and also known as a 3.5G technology. It provides a downlink with data transmission up to 8.10 Mbps.
Mailing List
A system that allow people to send e-mail to one address, where upon their messages is copied and send to all of the other subscribes to the list

Section 24 22.4.14
Today, we were learning the definition and the function of operating system. An operating system (OS) is a collection of software that manages computer hardware resources and provides common services for computer programs. The operating system is an essential component of the system software in a computer system. Application programs usually require an operating system to function.
- Function
The basic functions of an operating system are:
Today, we were learning the definition and the function of operating system. An operating system (OS) is a collection of software that manages computer hardware resources and provides common services for computer programs. The operating system is an essential component of the system software in a computer system. Application programs usually require an operating system to function.
- Function
The basic functions of an operating system are:
- Booting the computer
- Performs basic computer tasks eg managing the various peripheral devices eg mouse, keyboard
- Provides a user interface, e.g. command line, graphical user interface (GUI)
- Handles system resources such as computer's memory and sharing of the central processing unit (CPU) time by various applications or peripheral devices
- Provides file management which refers to the way that the operating system manipulates, stores, retrieves and saves data.
Different Types of Application Software
Word Processing Software: This software enables users to create and edit documents. The most popular examples of this type of software are MS-Word, Word Pad and Notepad among other text editors.

Presentation Software: The software that is used to display
information in the form of a slide show is known as presentation
software. This type of software includes three functions, namely,
editing that allows insertion and formatting of text, methods to include
graphics in the text and a functionality of executing slide shows.
Microsoft PowerPoint is the best example of presentation software.
Spreadsheet Software: Excel, Lotus 1-2-3 and Apple Numbers are some
examples of spreadsheet software. Spreadsheet software allows users to
perform calculations using spreadsheets. They simulate paper worksheets
by displaying multiple cells that make up a grid.
Database Software: Database is a structured collection of data. A
computer database relies on database software to organize data and
enable database users to perform database operations. Database software
allows users to store and retrieve data from databases. Examples are
Oracle, MSAccess, etc.
Multimedia Software: They allow users to create and play audio and
video files. They are capable of playing media files. Audio converters,
audio players, burners, video encoders and decoders are some forms of
multimedia software. Examples of this type of software include Real
Player and Media Player.
*Application software utilizes the capacities of a computer directly
for a dedicated task. Application software is able to manipulate text,
numbers and graphics. It can be in the form of software focused on a
certain single task like word processing, spreadsheet or playing of
audio and video files. Here we look at the application software types
along with some examples of application software
Describe the two types of software
Two types of software are application software and system software. Application software consists of programs that perform specific tasks for users, such as a word processing program, e-mail program, or Web browser. System software consists of the programs that control the operations of a computer and its devices. The two types of system software are operating systems and utility programs. An operating system (OS) is a set of programs containing instructions that coordinate all the activities among computer hardware devices. A utility program performs a specific task, usually related to managing a computer, its devices, or its programs.
Cross-platform computing is becoming increasingly important as local-area networks become better at linking machines of different types.
In computing, booting (or booting up) is the initialization of a computerized system. The system can be a computer or a computer appliance. The booting process can be "hard", after electrical power to the CPU is switched from off to on (in order to diagnose particular hardware errors), or "soft", when those power-on self-tests (POST) can be avoided. Soft booting can be initiated by hardware such as a button press, or by software command. Booting is complete when the normal, operative, runtime environment is attained.
