Introduction to the world of computers

allowed you to carry multiple devices safely

design computer systems

a very small devices with some type of built in computing or internet capability

raw and unorganized facts that can be forms of text, audio, video, graphics

the first page displayed when the browser is opened

one resource (a vast collection of web pages) available through the internet

fastest, expensive and powerful

performing operations on the data (processing)

a medium sized computer used to host programs and data for a small network

secure computers and networks against hackers

presenting the result (compute for the result)

may compact disk and reader kaya may moving parts sila

performs specific task or applications

Inexpensive personal computers. Computers use increased dramatically

collection of hardware and other devices that are connected together

Most students today have access to computers at school. some schools integrate ebooks into the curriculum

Programs used to tell the computer hardware what to do

Allow users to communicate with each others and to electronically access each other. MODEM(Modulator-Demodulator)

students participate from location other than traditional classroom setting using computers and internet access

Computer Professionals includes programmers, system analyst, computer operations personnel, security specialist

Computers were large and expensive. Computers were run by vacuum tubes. Were mostly used for high volume process task

data that has been processed into a meaningful form

Looking up information, Exchange email, Shopping, Watching Tv, Download music and movies, etc...

saving data, programs or output for future use(storing data)

Household tasks are monitored and controlled by a main computer in the house

used to perform large processing task for business

usually use a digital pen/stylus or touch screen

present results to the user like monitors, printer, speakers, projectors etc...

can look like a USB flash drive or small circuit board

entering data into the computer (we enter raw data)

colleges and universities are even more integrated. some have computer requirements for enrollment

used transistors. Were small, powerfull,cheaper and more energy efficiency and more reliable. Punch card and magnetic

smaller and have more limited features than conventional notebooks

Enormous and powered by vacuum tubes. used a great deal of electricity and generated a lot of heat. ENIAC and UNIVAC

username, @symbol. Domain name for the computer that will be handling the person's email (Mail server)

sending or receiving data

walang moving parts and purely ISIS. non volatile

designed to be carried around easily.
