Title: CIS 105 Survey of Computer Information Systems


1
CIS 105 Survey of Computer Information Systems
  • Essential Concepts and Terminology
  • Study Unit 5

2
UNIX.
  • A multi-user, multi-tasking server operating
    system designed to work in a secure, centrally
    administered computer network.

3
Client/Server Architecture.
  • A network architecture in which processing is
    split between workstations (clients) and the
    server.

4
DOS (MS-DOS).
  • DOS (disk operating system) was the operating
    system software developed for 16-bit Intel
    processors and shipped with the first IBM PCs,
    and until the introduction of Microsoft Windows.
    DOS uses a command-line user interface.

5
Macintosh Computer (Mac).
  • A microcomputer platform manufactured primarily
    by Apple Computer Inc. and based on a proprietary
    architecture. Mac OS introduced the graphical
    user interface in 1984.

6
Protected Mode.
  • The processing mode introduced with Windows 3.0
    that allows users to access virtually unlimited
    amounts of memory.

7
Windows 3.x.
  • MS-DOS applications that switch Intel processors
    into protected mode. The work with only 16 bits
    and use cooperative multitasking.

8
Windows 95.
  • A true operating system supporting 32-bit
    processing and featuring preemptive multitasking.

9
Windows 98.
  • An improved version of Windows 95 offering better
    stability, improved Internet connectivity and
    updated drivers for improved peripherals,
    including DVD-ROM and USB connections.

10
Linux.
  • An operating system for Intel-based and other PCs
    that is a derivative of Unix and available as
    freeware.

11
File Manager.
  • Utility software, such as Windows Explorer, that
    helps users locate, rename, move, copy, and
    delete files.

12
File.
  • A named collection of data (such as a computer
    program, document, or graphic) that exists on a
    storage medium.

13
Extension.
  • The part of a filename indicating the type of
    data in a file. The extension follows the
    file-name and is separated from the filename by a
    period.

14
File Finder.
  • An operating system utility that enables
    searching a computer for files using a variety of
    criteria.

15
Backup Utility.
  • Programming that copies data from the hard disk
    to backup media, often incrementally at specified
    intervals.

16
Antivirus software.
  • A computer program used to scan a computer's
    memory and disks to identify, isolate, and
    eliminate viruses.

17
File Compression.
  • A type of data compression that shrinks one or
    more files into a single file that occupies less
    storage space than the files did separately.
