CIOS

Specialty Definition: Ios

(From Wikipedia, the free Encyclopedia)

Ios (locally Nios) is an island in the Cyclades group in the Aegean Sea. It is a part of Greece.

Ios is a hilly island with cliffs down to the sea on most sides, situated halfway between Paros and Santorini. It is about 18 km (11 mi) long, 10 km (6 mi) wide, with an area of about 105 sq km (41 sq mi). Population was 1,100 in 1992 (down from 3,500 in the 19th century).

The main town is Ios, at the head of the Ormos harbor in the northwest.

Ios has left little impression on history. Ancient tradition said that Homer's mother was from Ios, and that he himself was buried there--and indeed the locals will show visitors the site of the ancient town of Plakatos at the northernmost end of the island, where the rocky entrance to a tomb may be seen. There is no physical evidence connecting this with Homer however. There are signs of Mycenaean settlement.

The north end of Ios also has a ruined Venetian castle from the 15th century. The island is said to have 150 churches and chapels.

Ios attracts very large numbers of young tourists, many of whom sleep on the beaches after partying through of the night. (A typical slogan, as seen at www.magicaljourneys.com: "Ios: Where Spring Break Lasts All Summer") Milopotamos (or Milopota) is the most popular of the beaches.

IOS

(From Wikipedia, the free Encyclopedia)

The IOS stands for Internetwork Operating System. It provides the command line interface to many Cisco Systems brand routers, and being an operating system, also contains command execution and actual routing software. It is very similar in structure to MS-DOS and Linux, as well as other router operating systems.

Command prompt output:

• User Mode: Router>
• Priveledged Exec Mode: Router#

command format:

Commands are single words. Arguments are interpreted when a space seperates the argument from the command. Cisco calls arguments subcommands. Command-line arguments may contain dashes.

• Example: show running-config. (shows the active configuration.)

Autocomplete

Unlike most operating systems, the CIOS has so few commands that it will interpret truncated commands without requiring the user to autocomplete the command. Entering a command that requires an argument without an argument will produce:

%Incomplete Command.

To display arguments use the "?" argument. ("?" is also the help command.)

Command History

Like most operating systems, the CIOS has a command history. It can be accessed using the up and down arrow keys (like other operating systems.)

Mode(s)

Commands will not be shown to users that or do not have sufficient privilege to access them. Commands will fail to execute as if they don't exist. The highest priveledge mode for a user is the "Priveleged Exec" mode. (accessible using the Enable command).

Administrators should also be familiar with the following modes:

• Global Configuration Mode.
• config-mode
• Rxboot mode
