Introduction to ICTIntroduction to ICTWhat is Information Technology (IT)?
An Information Technology (IT) system processes, stores, and/or transfers (communicates) information
Information can take many different forms such as text, numbers, pictures, sound, video, and multimedia
To transfer information, IT systems use computers, telecommunications networks, and other electronic devices
Because of the importance of communications in IT, the term Information and Communication Technology (ICT) is often preferred to IT
Since IT involves many different and often highly specialized areas, it is often seen as a very daunting subject
However, the basis of IT is simply to help us to improve the way we deal with information in all areas of our lives
What is IT used for?IT is used in business, academia, industry, government, heath care, etc.It is also an important in part of our everyday activities

Introduction to ICT (2)Introduction to ICT (2)Computers enable us to process information and perform specific
tasks much more quickly than we could do ourselvesIT systems are very Flexible and can be made to perform a variety
of different tasksIT networks (e.g., Internet) allow us to distribute and share
information quickly, and over a very long distanceMany developments in IT are designed to make our lives easier
But people expectations of what they (and others) can achieve are often leading to unrealistic demands being placed on people and the technology around them
We live in an "Information Society“ The effective use of information is regarded as the defying
element of the 20th – 21st centuries, as important as the industrial revolution before it

Computer Components (1)Computer Components (1) The main components used to build a personal computer and
other types of microcomputers are: Computers are made up of many components Internal Components
that is, they are located inside the computer case External Components
Some are connected externally, using portsA port is a kind of plug, usually located at the back of the computer
Components located outside the computer's case are referred to as peripheral devices
Because they use components, PCs are customizable

Computer Components (2)Computer Components (2) You can add internal or external components for specific tasks, such
as playing sound, and choose mare powerful components to make a high performance PC
Or you can specify less powerful, less expensive components for a basic office computer
This means that PCs vary quite widely in terms of performance (the speed at which a computer performs different tasks), cost, and the sort of applications (software) that they can run.
Computer components can be divided into the following categories:Microprocessors process instructions and perform calculations.Storage devices (memory and disks) hold data.Input devices (mouse and keyboard) let the user enter data.Output devices (monitor, speakers, and printer) (display data).Network devices (network card, modem) allow computers to
transfer data to and from other computers.

Computer Devices (4)Computer Devices (4)Mouse
Computers are usually operated through a graphical user interface (GU[). This means that the user selects a command from the computer's screen display by moving a pointer and clicking an icon.
A mouse is the device usually used to control the movement of the pointer on the screen
A mouse is used by moving it across a mouse mat or other flat surface. This moves a ball on the bottom of the mouse, The movement of the ball sends a signal to the computer. Software interprets this signal and performs an operation, such as moving a cursor or drawing a line.
A mouse has two or more buttons on top of it, the function of which depend upon the software being used.

Storage Components (1)Storage Components (1)Memory and disks are the components used to store data for
processingUnits of measure (i.e., capacity of storage) are bits, Bytes,
megabytes, and gigabytesA bit
a binary or logical 1 or 0, which is the lowest unit of measure of information
A Byteis a chunk of bits (combination of bits) used to represent a
information (e.g., character)There are usually eight bits in a byteE.g., 01000001 is used to represent the letter A in binary codeBytes are commonly abbreviated with a capital B and bits are
abbreviated with lower-case b, but not alwaysMore often, hardware and software are described as being a
certain number of bits

Storage Components (2)Storage Components (2) This refers to how much information the hardware or software can
process at any one time E.g., if a CPU is a 32-bit processor, it means that the CPU can
process 32 bits of data in each clock cycle Popular Measures
1. Kilobyte (denoted as KB) A kilobyte (KB) Is 1024 bytes, The size of a data file is often measured in kilobytes Why is kilobyte not “1000” bytes?
2. Megabyte (denoted as MB) A megabyte is 1,048,576 bytes (1024 kilobytes) A megabyte (MB) is often used to measure the amount of main
memory or the size of a collection of files within a Folder A megabyte is about as much data as 500 pages of double-
spaced text Why is Megabyte not “1,000,000” bytes?

Types of Storage (1)Types of Storage (1) Memory is one of the most essential parts of the computer From the moment you turn your computer on until the time you shut
it clown, your CPU is constantly using memory There are 3 types of storage used by the computer when storing
data
1. Read-only Memory (ROM) ROM stores the data necessary to start the computer and
identify its component ROM is non-volatile or persistent memory that holds permanent
information, such as the BIOS software that enables the components in the computer to communicate with each other
Data stored In ROM is not deleted when the computer is switched off
It cannot usually be deleted or overwritten in the course of normal computer operations

Types of Storage (2)Types of Storage (2)2. Random Access Memory (RAM)
RAM stores data while it is being processed. E.g., RAM is required to run software while the computer is powered
RAM, is volatile or non-persistent memory, is a temporary memory store
Data held in RAM is only stored while the computer is switched on E.g., when you create a document (such as a letter), the
document is stored in your computer's RAM, until you save it to disk
RAM holds data required by the CPU, which cannot store large amounts of data itself
RAM is important because it enables the CPU to get data quickly E.g., when a software application is started, the data needed to
run the program is copied from the main disk into RAM, where the CPU can access it

Types of Storage (3)Types of Storage (3)
3. Storage Disks or Drives Disk dives invented in the 1950s, are used to store and
transfer data files Magnetic disks or drives are used to preserve data when the
computer is turned off and to move and backup data When data is entered into a computer, it must be saved as a
file to preserve it when the computer is switched off Also, software applications need to install files on the main
disk drive in the computer in order to run The most important type of long term storage component in
the desktop computer is the hard disk, which is used to store the software and data on which the computer runs

Types of Storage (4)Types of Storage (4)Hard disks have a hard platter that holds the
magnetic medium, as opposed to the flexible plastic film found in tapes and floppies
The magnetic disk can be easily erased and rewritten, and it will "remember" the magnetic flux patterns stored for many years.
Many computers will also have removable disk drives to install software and backup data files

Disk capacity is principally a question of capacity: how much data can be stored an the disk?
Disk performance is determined by other factors including the seek time (the time it takes to find data on the drive) and the transfer rate (the speed at which data can be moved to and from a disk)

Types of Storage (4)Types of Storage (4) Other Magnetic Media
Other magnetic disk devices, such as Iomega Zip and Jaz clicks, are also available
These disks tend to offer much less capacity than a hard disk (although much more than a floppy disk)
The main advantage is that the disks can be removed and transferred elsewhere.
One of the most popular external magnetic storage options available today is the Universal Serial Bus (USB) flash drive
These can store hundreds of times the information found on a standard floppy, and don't need a special reader
Instead, USB drives pop into a standard USB port on the desktop or laptop computer
