FIRST PICTURE

In banks, computers store information about the money held by each customer

and enable staff to access large databases and to carry out financial transactions

at high speed. Computers are used to automate the accounts of customers

classified in savings, checking, loans and various investments. The computerkeeps track of customer account records through a record transaction history.

They also control the cashpoints, which dispense money to costumer by the use

of pin- protected card.

Computers are also vital in supporting the activities of the bank branches.

Internet Banking offers bank customers the option of online banking through a

licensed bank website.

SECOND PICTURE

In education, computers help students to perform mathematical operations and

improve their maths skill. They are used to access the internet, to do researchand to communicate with other students around the world. Teachers use

projectors and interactive whiteboards to give presentations and teach sciences,

history or language courses. PCs are also used for administrative purpose. A

school website allows teachers to publish exercise for students to complete

online. Students can also enroll for courses via the website and parents can

download official reports.

THIRD PICTURE

Some of the uses of computers in airports are:

1) Air traffic control, landing and takeoff of aircraft, radar systemmanagement, weather conditions from the Control Tower.

2) The control of the flight instruments on airplanes.3) Airport security.4) The baggage check.5) Communication between travel agencies and the airlines to book and

buy tickets flight, departures and arrivals, schedules, etc.6) Car rental.7) Management of parking spaces.8) Etc.

FOURTH PICTURE

1) Telephone, calculators, the cars electronic ignition, the timer in the microwave,or the programmer inside the VCR, etc.

2) Hardware and software.3) Letters, memos or legal document, customers lists, accounts, inventories,etc.4) Because with the computer we can communicate with other computers and other

people around the world and send and receive information.

The basic cycle of operation of computers is based primarily on the input, process and

output information .

Inputs:is the process of introducing computer data, instructions or information needed

from input devices such as mouse , keyboard, etc. .

Process:It is what transforms an input to the system output , the data must be

processed , reach the processor or central processing unit (CPU),which basically

consists of the following elements the ALU ( Arithmetic Logic Unit ) and the control

unit that data are obtained through the ram.

Storage ** : The information is stored on the hard drive

Outputs :It is a device by which the results of the programs implemented in thecomputer or in other words the results obtained are obtained by processing the inputs.

The devices why we can see the results are monitors , printers , Speaker , Headset ,Plotter , Projector , etc. .

Laptops mark is Dell and the model is the INSPIRON 9200.

It has an intel core duo processor speed of 2.4 gigahertz processing speed. The RAM

is 2048 megabytes expandable to 4 GB and hard drive capacity is 500 GB.

Comes with pre-installed Windows Vista Home Premium.

1) The microprocessor (or just processor) is the central and most complexintegrated circuit of a computer system. Is often called the "brain" of a computer.

It is an integrated circuit made up of millions of electronic components. It is the

central processing unit (CPU) of a PC.

It is responsible for implementing programs from the operating system to the

user applications, only running on programmed instructions low level language,

making simple things such as add, subtract, multiply, divide arithmetic and

logical operations, binary logic and accesses memory.

This central processing unit consists of registers, a control unit, arithmetic logic

unit (ALU) and a calculation unit floating point.

2) The speed of the CPU or processor in a computer is measured in number ofcycles per second cycles or frecuency, namely measures the number ofinstructions or operations that the processor can perform per second. This

number is too called clock speed (clock speed). Each cycle per second is one

hertz. Hertz few others have, the higher the speed of a computer processingorders, although this rate may be influenced by many other factors. Multiples of

hertz is used to measure the speed of the processor (1 megahertz (1000 Hz),

1gigahertzios 1000000 Hz)

3) The random access memory (RAM) is used as a working memory for theoperating system, programs, and most software. That's where all the instructions

the processor running and other computational units are loaded. They are called

"random access" because you can read or write to a memory location with a

timeout equal to any position, they need not follow an order to access theinformation as quickly as possible.

1) The CPU consists of control unit, registers (memory elements containinginformation on the program is running and control of the processor itself) and

the arithmetic and logic unit of a computer, that is, the block executes

instructions that are located in memory.

2) The arithmetic logic unit (ALU) performs mathematical calculations( +,-,etc.)and logical operations( AND, OR, NOT).

3) A system clock sends out signals at fixed intervals to measure an synchronizethe flow of data.

4) 1 GHz es one thousand million hertz, or cycles per second.5) RAM6) ROM7)

RAM capacity can be expanded by adding extra chips, usually contained insmall circuit boards called dual in-line memory modules( DIMMs)

8) Motherboard.9) Buses is electrical channels which allow devices inside the computer to

communicate with each other.

10) Expansion slots allow users to install expansion cards, adding features likesound, memory and network capabilities.

2) A laptop is likely moreexpensive than the equivalent desktop, but alaptop is less practical if you travel a lot( Comparing)

3) What'sthe storage capacity of the hard drive?(Asking for technicalspecs)

4) I'm looking fora desktop PC that has good graphics for games.( Explaining what you are looking for)

5) Do you need any help? ( Greeting and offering help)

6) And, how much does the PDA cost? ( Asking the price)

7) This workstation hasa Pentium processor with dual- core technology,
