2. An electronic, programmable, multiuse machine that
accepts, processes, stores data and sends output as a
useful result.
A device capable of performing a series of arithmetic or
logical operations.
A computer is distinguished from a calculating
machine, such as an electronic calculator or calculating
machine, device for performing numerical
computations; it may be
mechanical, electromechanical, or electronic. The
electronic computer is also a calculator but performs
other functions as well and by being able to store a
computer program.
3. Input
Accepts data, through input devices like
keyboard, mouse, scanner and the like.
Process
Manipulate input
Output
Produces output, through monitor, printer and the
like.
Stores
keep data for future needs
4. Hardware, physical components of computer that you
can actually touch such as keyboard, monitor, system
unit, mouse, printer and the like.
Software, sets of instructions use to direct the hardware
on how to run data into useful information for people use.
These are programs used by the user to interact with the
computer.
People ware, they are most important factor in a
computer. The y manipulate and program the computer
system to make it useful.
5.
6. The name analog came from the word
analogous meaning similar. These are computers
used for scientific, engineering and process-control
purposes. It deals with quantities that continuously
variable, they give only approximate result.
Is the machine specializes in counting. These
machines are used for both business an scientific
purposes.
These are computers that combine the
measuring the capabilities of the analog and control
capabilities of the digital computer.
7. CAPACITY
The term refers to the volume of work of the
data processing capability computer.
8. 1. Amount of data that can be stored in memory.
2. Speed of internal operation of the computer.
3. Number and types of peripheral devices.
4. Amount and type of software available for the
computer.
9. Also known as the personal
computer (PC).these are typically
found in homes and small
offices, business and etc.
It includes the
Laptop, Notebook, Personal Digital
Assistant (PDA)
10. These computer small but powerful than a
microcomputer.
It can carry out the processing tasks for several
people working and terminals that are
connected to the minicomputer.
Terminal- is an input and output device
that resembles a microcomputer because it has
keyboard and screen but does not have
processing capacity.
11. It is large, fast and fairy expensive computer.
Generally used by business or government to
provide centralized storage, processing and
management for large amount of data.
They are actually the bigger version of
minicomputers such that handles more amount
of data and bigger number of users.
12. The fastest and most expensive type of
computer designed for “ computer-intensive”
tasks such as molecular modeling, code
breaking and weather prediction.
It can process more than one trillion
instructions per second. Making it possible to
perform complex tasks such as modeling the
movement of thousands of particle sin tornado
or creating realistic animations.
13. Ability to perform certain logic operations.
Ability to provide new time dimensions.
Ability to control error.
Ability to check itself.
14. Dependence on prepared instructions.
Inability to provide meaning from
objects.
Inability to generate information.
It cannot correct wrong instructions.
15. Input errors.
Errors in instructing a computer.
Communication gap.
Improper controls.
Lack of standards.
Lack of adequate manufacture
support.
