It maintains two subarrays - the sorted subarray and the unsorted subarray. In each iteration, it selects the minimum element from the unsorted subarray and inserts it into the sorted subarray. This process continues until the entire array is sorted.
The document describes the binary search algorithm for searching a sorted array. It has a time complexity of O(Logn) compared to linear search which is O(n). Binary search works by comparing the target value to the middle element of the array and recursively searching either the left or right half depending on if the target is less than or greater than the middle element. Implementations of both recursive and iterative binary search in C are provided.
The document provides an overview of JSON (JavaScript Object Notation) including its syntax, structure, and common uses. JSON is a lightweight data-interchange format that is easy for humans to read and write and easy for machines to parse and generate. It is built on two structures: a collection of name/value pairs and an ordered list of values. JSON is primarily used to transmit data between a web server and web application.
A stemming algorithm reduces inflected words to their word stem or root form. It works by removing suffixes and endings while trying to leave the stem in a familiar form. Developing a good stemming algorithm requires understanding the language's grammar, morphology, and common word forms. The algorithm is built incrementally and rules are evaluated based on whether they improve or degrade search performance across a test vocabulary. Irregular forms and stopwords also need to be handled.
To configure a DHCP server role in Windows Server, an administrator must first log into the server, open the Server Manager, add the DHCP Server role via the Add Roles Wizard, configure the network interfaces, DNS and WINS settings, and add DHCP scopes defining the IP range, subnet mask, default gateway and lease time; once installed, the DHCP server interface can be accessed from the Administrative Tools menu.
The document provides an overview of networking concepts including:
1) A network consists of devices that exchange data over media, with hosts having logical addresses. Common host types include workstations, servers, and routers.
2) Protocols establish rules for network functions, while bandwidth refers to the amount of data that can be transmitted in a given time period.
3) Network topologies determine how devices are physically connected, with common types being bus, star, and ring configurations.
4) Networks are generally local area networks (LANs) or wide area networks (WANs) connecting multiple LANs across a wide geographic region.
A network connects devices that exchange data over media. A host has a logical network address and can be devices like workstations, servers, printers. Protocols are agreed upon rules for network functions. The network topology refers to the physical layout, such as bus, star, or ring. Networks are LANs for small areas or WANs connecting multiple LANs over wide areas. Devices include routers, switches, bridges, firewalls, and more.
A network consists of systems and devices that exchange data over media like cables. Hosts have logical addresses and can be devices like workstations, servers, printers. Data is transmitted in bits, which are 1s and 0s. Protocols are agreed upon rules for network functions. Bandwidth is the amount of data transmitted per second. Network topologies include bus, star, and ring shapes. LANs serve small areas while WANs connect LANs over wide areas using leased lines. The OSI model splits communication into 7 layers with each layer performing a specific function independently. Physical layer devices connect wiring, data link devices include bridges and switches, and network layer devices route between logical addresses.
A network is a collection of systems and devices exchanging data over some form of media. Hosts can be workstations, servers, printers, connection devices, or routers. Data is transmitted in bits, which are 1s and 0s, and protocols define rules for network functions. Common network topologies include bus, ring, star, and token passing ring. Networks can be LANs, covering a small area, or WANs connecting multiple LANs over a wide geographic area using leased lines. The OSI model organizes network communication into seven layers, with each layer adding a header and the data link layer adding a trailer for encapsulation.

The document is intended to teach the basics of shell scripting through explanations and code samples.
Perl can be obtained from various sources including downloading the source code from perl.com or getting binary packages from ActiveState for Linux, Solaris, and Windows. Installing Perl on Linux/UNIX involves checking the version with the perl -v command and installing RPM packages with rpm or building from source which involves extracting, configuring, making, testing, and installing. Installing on Windows is straightforward using the ActiveState Perl installer and optionally configuring support for IIS or PWS web servers.
2. Apache is the most popular Web server on the Internet.
Apache is a server that responds to requests from Web browsers, or clients,
such as Firefox, Netscape, lynx, elinks, and Inter net Explorer
3. Apache and httpd
Apache is the name of a server that serves HTTP and other content.
An Apache server is the same thing as an Apache process.
An Apache server normally uses TCP port 80; a secure server uses TCP port 443.
If the Apache server system is running a firewall or is behind a firewall, you must
open one or both of these ports.
To get started, open port 80 (HTTP). Using systemconfig-firewall, select WWW
(HTTPD) and/or Secure WWW (HTTPS).
4. Because Apache serves content on privileged ports, you must start it
running with root privileges.
The root of the directory hierarchy that Apache serves content from is
called the document root and is controlled by the DocumentRoot
directive. This directive defines a directory on the server that maps to /.
This directory appears to users who are browsing a Web site as the root
directory. As distributed by Fedora/RHEL, the document root is
/var/www/html.
5. The last command adds username to the webwork group; you must repeat this command for
each user you want to add to the group.
# groupadd webwork
# chmod g+rws /var/www/html
# chown: webwork /var/www/html
# usermod -aG webwork username
6. Running an Apache Web Server
Install the following packages:
httpd
apr (Apache portable runtime; installed with httpd)
apr-util (installed with httpd)
7. httpd init script
Run chkconfig to cause httpd to start when the system enters multiuser mode:
chkconfig httpd on
After you configure Apache, use service to start httpd:
service httpd start
8. After changing the Apache configuration, restart httpd with the following
command, which will not disturb clients connected to the server:
Getting Apache Up and Running
To get Apache up and running, modify the /etc/httpd/conf/httpd.conf
configuration file as described in this section.
9. Modifying the httpd.conf Configuration File.
Apache runs as installed, but it is a good idea to add/modify the three lines of
the /etc/httpd/conf/httpd.conf configuration file described in this section
before starting Apache. If you do not add/modify these lines, Apache will
assign values that might not work on the server.
10. Testing Apache
Once you start the httpd daemon, you can confirm that Apache is
working correctly by pointing a browser on the local (server) system to
http://localhost/.
11. Putting Content in Place
Place the content you want Apache to serve in /var/www/html. Apache
automatically displays the file named index.html in this directory. Working
with root privileges (or as a member of the group you set up for this
purpose [e.g., webwork]), create such a page:
# cat /var/www/html/index.html
<html><body><p>This is <i>my</i> test page.</p></body></html>
12. Configuration Directives
Configuration directives, or simply directives, are lines in a configuration file
that control some aspect of how Apache functions. A configuration
directive is composed of a keyword followed by one or more arguments
separated by SPACEs. For example, the following configuration directive
sets Timeout to 300 (seconds):
Timeout 300
13. DocumentRoot Points to the root of the directory hierarchy that holds the server’s content.
where dirname is the absolute pathname of the directory at the root of the directory
hierarchy that holds the content Apache serves. Do not use a trailing slash.
You can put the document root wherever you like, as long as the user apache has read
access to the ordinary files and execute access to the directory files in the directory
hierarchy. Access control includes both discretionary access controls (chmod, including
ACLs for the user apache) and mandatory access controls (selinux for httpd). The following
directive puts the document root at /srv/www:
15. Global Environment
When queried, to return the name of the operating system and the
complete version number of Apache:
ServerTokens OS
/etc/httpd, which is the pathname that Apache prepends to relative
pathnames in httpd.conf:
16. Apache executes the directives in an <IfModule> container only if the
specified module is loaded. The httpd.conf file holds two <IfModule>
containers that configure Apache differently, depending on which
module—prefork or worker—is loaded. Fedora/RHEL ships with the prefork
module loaded; this section does not discuss the <IfModule> container
for the worker module. (The worker module does not work with PHP. See
the comments in the /etc/sysconfig/httpd file if you want to load the
worker module.)
17. DefaultType The DefaultType directive specifies the content-type Apache
sends if it cannot determine a type.
DefaultType text/plain
Listen 80
Include an IP address in this directive to prevent Apache from listening on
all network interfaces:
Listen 192.0.32.10:80
18. includes the files that match *.conf in the /etc/httpd/conf.d directory, as
though they were part of httpd.conf:
Include conf.d/*.conf
19. When you install Apache, there is no index.html file in /var/www/html;
when you point a browser at the local Web server, Apache generates
error 403 (Forbidden), which returns the Fedora/RHEL test page. The
mechanism by which this page is returned is convoluted: The Fedora/RHEL
httpd.conf file holds an Include directive that includes all files with a
filename extension of .conf that reside in the conf.d directory that is in
the ServerRoot directory (/etc/httpd
20. Main Server Configuration
ServerName As Fedora/RHEL Apache is installed, ServerAdmin is set to
root@localhost and the ServerName directive is commented out. Uncomment
ServerName and change both to useful values as suggested in the
ServerAdmin
The DocumentRoot directive
DocumentRoot "/var/www/html”
Modify this directive only if you want to put content somewhere other than in
the /var/www/html directory.
21. <Directory> The following <Directory> container
sets up a restrictive environment for the entire local filesystem (specified by
/): <Directory />
Options FollowSymLinks
AllowOverride None
</Directory>
22. Next, another <Directory> container sets up less restrictive options for the
DocumentRoot (/var/www/html). The code in httpd.conf is interspersed with
many comments.
Without the comments it looks like this:
<Directory "/var/www/html">
Options Indexes FollowSymLinks
AllowOverride None
Order allow,deny
Allow from all
</Directory>
23. Virtual Hosts
Apache can respond to a request for a URI by asking the client to request a different URI.
This response is called a redirect. A redirect works because redirection is part of the HTTP
implementation: Apache sends the appropriate response code and the new URI, and a
compliant browser requests the new location.
The Redirect directive can establish an explicit redirect that sends a client to a different
page when a Web site is moved. Or, when a user enters the URI of a directory in a browser
but leaves off the trailing slash, Apache can automatically redirect the client to the same
URI terminated with a slash.
24. assume the server with the name zach.example.com and the alias
www.example.com has ServerName set to www.example.com.
When UseCanonicalName is set to On, Apache uses the value of
ServerName and returns www.example.com/dir/. With
UseCanonicalName set to Off, Apache uses the name from the incoming
request and returns zach.example.com/dir/.
25. Content Negotiation
Negotiation Apache can serve multiple versions of the same page, using a
client’s preference to determine which version to send. The process
Apache uses to determine which version of a page (file) to send is called
content negotiation. Apache supports two methods of content
negotiation: type maps and MultiViews search, which can work together.
26. Type Maps
The following AddHandler directive from httpd.conf tells Apache to use any filename
ending in .var as a type map:
AddHandler type-map var
To see how type maps work, create the following files in /var/www/html:
$ cat /var/www/html/index.html.en
<html><body><h1>Hello</h1></body></html>
$ cat /var/www/html/index.html.fr
<html><body><h1>Bonjour</h1><body></html>
$ cat /var/www/html/index.html.var
URI: index.html.en
Content-Language: en
Content-type: text/html; charset=ISO-8859-1
URI: index.html.fr
Content-Language: fr
Content-type: text/html; charset=ISO-8859-1
27. Virtual Hosts
Apache supports virtual hosts, which means that one instance of Apache can respond to
requests directed to multiple IP addresses or hostnames as though it were multiple servers. Each
IP address or hostname can then provide different content and be configured differently.
There are two types of virtual hosts: host-by-name (also called host-based) and host-by-IP. Host-
by-name relies on the FQDN the client uses in its request to Apache—for example,
www.example.com versus www2.example.com. Host-by-IP examines the IP address the host
resolves as and responds according to that match.
28. Host-by-name is handy if there is only one IP address, but Apache must support
multiple FQDNs. Although you can use host-by-IP if a given Web server has aliases,
Apache should serve the same content regardless of which name is used.
The NameVirtualHost directive specifies which IP address supports host-byname
virtual hosting; the ServerName (or ServerAlias) directive must match the
client request to match that virtual host. Without a NameVirtualHost directive,
the virtual host is a host-by-IP virtual host; the ServerName directive specifies
the name the server uses to identify itself.
