Introduction about I.C.T.
Introduction about I.C.T.
I C T simply means information communication technology. It deals with
Various ways the computer works, together with other telecommunication equipment which are needed in data processing and information transmission to solve problems in different aspects of human endeavour. it is the acquisition,
Processing, storage of vocal, textual, numerical and pictorial information by a micro-electronic based combination of computer and other tele- communications. information technology is important because it brings about the fussion of several important industries dealing with computers, telephone, fax machine, television, internet and various hard held devices.
Components of ICT.
Computer, fax machine, mobile cell phones, internet, telephone are all components of ICT.
WHAT IS COMPUTER.
A computer is any machine or device which under the control of a stored program can accept data in a prescribed form, process the data, and supplied the result as information in a specific form. It can not produce good output from bad one.it gives you what you put in. A computer takes in data through the input unit and after porcessing it at the central processing unit, it gives out result at the output unit. Computer is not a simple machine but a machine comprising different component parts that work together harmoniously at a fantastic speed to give an accurate desired result.
Types of computer.
Computers are classified in many ways. in term of mode of operation, there are three types of computer. e.g. Analog, Digital and hybrid.l
ANALOG COMPUTER : - this
includes thermometers, dispensers at the petrol stations. they are mostly used in industrial operation. in it, result of processing a solution to an equation is produced through the operation of calibrated moving parts of electrical signals. the outputs may be in wave or readout formats.
DIGITAL CoMPUTERS: - this is the type of computes seen in schools or offices. it functions with actual. it accepts inputs; transforms, before processing the information. Hybrid computers combine the properties of both digital and Analog. it is not too common. However, computers can further be classified based on size and other considerations. we have micro (small), Mini (medium), mainframe (big) and super (very big) computers.
MOBILE CELL PHONE: this is of different types. it has been among us. we have Analog or digital mobile cellular phones.
FIG. 22. 1 MOBILE CELL PHONE PHONES
Are designed primarily for communicating by voice through a system of ground area cell is hexagonal in shape usually 8 served by a transmitting receiving tower. Digital mobile cellular phone turn your voice message into digital bits which are sent through the airwaves, then decoded back into your voice by the cellular handset unlike analog.
FAX MACHINES: A fax machine
Or facsimile transmission machine scans an image on paper and scans an image on machine scans an image on paper and sends it as electronic signals over telephone lines to a receiving fax machine, which recreates the image on paper. see fig facsimile means ("an exact copy). It can also scan and send na image to a fax modern inside a remote computer. This fax can be displayed on the screen. stored or printed out by computers printer.
USES OF ICT IN DIFFERENT ORGNIZATIOS.c
government: - the government use ICT for:
Banks and financial institutions, hospitals, educational institutions business licence system politics such as voters registration during election
Census
Vehicle registration system and trafficINDUSTRIES USE ICT TO:
Monitor and control all machines involved in the transformation of raw materials to finished products known as process control. In a chemical plant for instance, computer when connected to different meters, thermometers, flow meter, pressure gauges, etc of the plant can monitor and control the temperature pressure of flow rate and since this control is automated, the production process is more efficient, less burdensome and more economical than the manual process.
E. Cost and budget
management

HEAlth INSTITUTIONS:
ICT is used in the health section like hospitals:
Hospital information system like collection date and histories for patients, accounting, etc which are then made available to doctors, nurses and other health workers for applications.
Diagnosis and drug a d m i n i s t r a t i o n : - computers can be used to maintain updated information pattern of existing illness, new illness and new findings.
With computers, physicians can diagnoses specific illness and even recommend treatment.
IMPORTANCE OF ICT
ICT networks or components enhance the ability of data collection and analysis, ease of communication, assists genetic coding, and exchange sharing, preserve and protect information. The networks can also make it easier to share expensive hard wares and soft ware.
