1) What is Computer? ▪ A computer is a very powerful and fast computing (calculating) machine. a COMPUTER can be defined as “a device that can perform both arithmetic and non-arithmetic operations accurately on any data or information at a very high speed”. ▪ The set of instructions given to the computer is called a program. ▪ A program can be defined as a set of instructions, which directs the computer to produce the desired results. 4

Computer components 5

2) Basic Applications of Computer ▪ Schools ▪ Multimedia and hospital administration ▪ Ticketing ▪ Banks and Insurance ▪ Scientific and engineering applications ▪ Business and administrative applications ▪ Avionics and space flights ▪ Humanities ▪ Police Work ▪ Meteorology ▪ Entertainment 6

3) Components of Computer System 7

The Central Processing Unit ▪ The Central Processing Unit (CPU) performs the actual computation inside any computer ▪ The CPU is a microprocessor made up of millions of microscopic transistors embedded in a circuit on a silicon wafer (or chip) ▪ The CPU and all components of a computer system process and store data using digital technology ▪ What is the unique characteristic of “digital” technology?

Digital Technology ▪ Today’s computers are based on integrated circuits (chips), each of which includes millions of subminiature transistors ▪ Each transistor can be in either an “on” or “off” position ▪ The “on-off” states of transistors are described using binary number system where each binary digit, or bit, has a value of either 1 or 0 ▪ This digital concept enables the storage and processing of characters, numbers, and various forms of multimedia

Computer Memory Capacity ▪ Kilobyte ▪ Approximately one thousand bytes ▪ A kilobyte is actually 1024 bytes (why?) ▪ Megabyte ▪ One million (106) bytes ▪ Gigabyte ▪ One billion (109) bytes ▪ Terabyte ▪ One trillion (1012) bytes ▪ Petabyte ▪ One quadrillion (1015) bytes ▪ Exabyte ▪ One quintillion (1018) bytes

4) Concepts of Hardware and Software 11

4) Concepts of Hardware and Software 12

5) Concept of Computing, Data and Information ▪ Computing ▪ The use or operation of computers, may involve computer hardware and/or software. ▪ Data ▪ The quantities, characters, or symbols on which operations are performed by a computer, which may be stored and transmitted in the form of electrical signals and recorded on magnetic, optical, or mechanical recording media. ▪ Information ▪ Facts provided or learned about something or someone. 13

Data and Information 14

System Software ▪ Handles the technical details ▪ Includes the operating system, utilities, device drivers, and language translators

6) Collaborative Learning (Google Docs, Google Drive, etc) ▪ Collaborative Learning ▪ an educational approach to teaching and learning that involves groups of students working together to solve a problem, complete a task, or create a product. ▪ Collaborative Learning tools ▪ Excellent collaborative tool. Students can work on the same document simultaneously with other students or teachers/lecturers to get feedback. 16

Features of collaborative learning/work ▪ Editing a document together ▪ Real time co-editing ▪ Groups/teams can work in parallel to learn/complete work/assignments faster 17

Features of collaborative learning/work ▪ Seeing changes in a document ▪ Review the changes since last viewed ▪ Version history – inspect past edits ▪ Restore versions 18

Features of collaborative learning/work ▪ Giving and receiving feedback ▪ Check other member’s task and give constructive feedback 19

Features of collaborative learning/work ▪ Assigning and completing tasks ▪ Separate the shared document into each member’s task ▪ Assign a group leader to facilitate the task 20

Features of collaborative learning/work ▪ Sharing with confidence ▪ Permission settings – can edit, can comment, can view 21

How would you use G Suite for collaborative learning ▪ If you were given a group project with 4 other members who does not have the same lecture schedule and who are living at different residential colleges, how would you use G Suite to complete your group project? ▪ Think (Think on your own) 2 minutes ▪ Pair (Find you partner, the student sitting next to you) ▪ Share (Share your solution with your partner and discuss your approaches) 22

7) What is an Operating System (OS) ▪ A collection of programs that handle technical tasks, including managing computer resources ▪ Every computer has an OS such as Windows 7 or Mac OS X ▪ The OS provides the interface between the user and computer, and is required to run applications

Functions of an OS ▪ Manages computer resources ▪ Coordinate memory, processing storage, and printers ▪ Monitor system performance ▪ Provide security ▪ Start-up the computer ▪ Provides user interface ▪ Character-based interface ▪ Graphical user interface (GUI) ▪ Runs applications ▪ Multitasking ▪ Foreground and background applications

Features of an Operating System ▪ Booting ▪ Features in common with application software ▪ Icons ▪ Pointers ▪ Windows ▪ Menus ▪ Dialog boxes ▪ Help

Categories of Operating Systems ▪ Hundreds of OS ▪ Three basic categories ▪ Embedded operating systems (handheld) ▪ Network operating systems (linked computers) ▪ Stand-alone operating systems (desktop)

8) Basics of Popular OS ▪ An OS is often called the software environment or platform ▪ Operating systems commonly used by individuals ▪ Windows – most widely used ▪ Mac OS – powerful and easy to use ▪ UNIX – network; originally designed for Web ▪ LINUX – non proprietary; free from the Web

Windows ▪ The most popular microcomputer operating system – over 90 percent of the market ▪ Comes in a variety of different versions ▪ Windows 7 provides several improvements over Windows Vista

Mac OS ▪ Mac OS X is designed to run on Apple computers ▪ One of the most innovative operating systems, but not used as widely as Windows ▪ Mac OS (Boot Camp) allows you to run both the Mac OS and Windows

UNIX and LINUX ▪ UNIX operating system ▪ Originally designed to run on networked minicomputers ▪ LINUX is a version of UNIX ▪ Open source ▪ Not proprietary

Virtualization ▪ Ability to support multiple operating systems on a single physical machine ▪ Virtualization software ▪ Physical machine can be logically separated into separate and independent virtual computers called virtual machines ▪ Host operating system ▪ Guest operating system

9) The User Interface ▪ The user interface (UI) is everything designed into an information device with which a person may interact. ▪ This can include: * display screens * keyboards * a mouse and * the appearance of a desktop. ▪ It is also the way through which a user interacts with an application or a website. 32
