SOFTWARE Flashcards
It is distinguished from hardware by its conceptual rather than physical nature.
SOFTWARE
consists of physical components
HARDWARE
needed to translate instructions created in human language
into machine language.
SOFTWARE
needed to make the computer
an economical work tool.
PACKAGED OR STORED SOFTWARE
It is much more practical and economical for one highly skilled person or programming team to develop programs that many
other people can buy and use to do common tasks.
PROGRAMMING
supplied as organized instruction sets called programs, or more typically as a set of related programs called a
package.
SOFTWARE
translate operations the user needs into language and instructions that the computer can understand. By itself,
computer hardware is merely a collection of printed circuits, plastic, metal, and wires.
PROGRAMS
3 Basic types of software
-SYSTEM SOFTWARE
-UTILITY PROGRAMS
-APPLICATIONS SOFTWARE
consists of a variety of programs that control the individual computer and make the user’s
application programs work well with the hardware.
SYSTEM SOFTWARE
consists of a set of instructions permanently burned onto a computer chip, it is truly a
combination of hardware and software.
BASIC INPUT/OUTPUT SYSTEM (BIOS)
straddle the line between hardware and
software.
FIMWARE
first level of system software.
OPERATING SYSTEM (OS)
overall controller of the work of the computer.
OPERATING SYSTEM (OS)
software loaded from the
hard drive into RAM as soon as the computer is turned on.
OPERATING SYSTEM (OS)
handle the connection between the CPU and peripherals.
OPERATING SYSTEM (OS)
connection between the CPU
and a peripheral or a user
INTERFACE
include programs designed to keep the computer system operating efficiently.
UTILITY SOFTWARE/PROGRAMS
including primarily anti-virus, firewall, and encryption programs, protect the
computer and its data from attacks that can destroy programs and data.
SECURITY SOFTWARE
serve primarily to guard against malicious programs inadvertently accessed,
usually through e-mail or downloads from the Internet.
ANTI-VIRUS UTILITIES
type of security program that makes it much harder for unauthorized persons or systems to enter the computer and hijack or damage programs or data on the computer.
FIREWALLS
encodes the data so that it cannot be read until it is decoded.
ENCRYPTION SOFTWARE
letters on a Web page address indicate that the site encrypts data sent through that site.
HTTPS
sufficiently high level that it cannot be decoded without a program at the receiver site.
ENCRYPTION
designed to help the user keep hard disk space clean and efficient.
DISK MANAGEMENT UTILITIES
moves data around on the disk so that small empty spaces are eliminated and
data and programs are relocated to better use the available space.
DEFRAGMENTER
These programs can also compress data to free up disk space, partition a disk so that the user has more control over where different types of information are stored, and clean up disks by eliminating unnecessary data and information.
DISK MANAGEMENT UTILITIES
serve to help the users back up their data.
BACKUP UTILITIES
The computer owner may not have a backup
copy of illegally downloaded programs.
ILLEGAL OR PIRATE PROGRAMS
A better choice is to back up one’s data
EXTERNAL (REMOVABLE) HARD DRIVE
ONLINE BACKUP LOCATION
computer programs that either blank the monitor screen or fill it with constantly
moving images when the user is away from the computer but does not turn it (and the monitor) completely off.
SCREEN SAVERS
CRT
CATHODE RAY TUBE
sometimes do require users to log back into their computer to turn off the screen saver, and those do have a security function.
SCREEN SAVERS
activate automatically if the computer does not receive any input from the user for a preset time period.
SCREEN SAVERS
