Switches are used within individual networks. To communicate with another network, the network would use a device called a router. A router is a special communications processor used to route packets of data through different networks, ensuring that the message sent gets to the correct address.

Basic Network Hardware

• Routers. A router is a connecting device that transfers data packets between different computer networks. ...
• Repeaters, Hubs, and Switches. Repeaters, hubs and switches connect network devices together so that they can function as a single segment. ...
• Bridges. A bridge connects two separate Ethernet network segments. ...
• Gateways.

Local Area Network (LAN): A LAN is a system of interlinked personal computers in a localized area, typically under 1 km across. LANs normally operate within a compact area such as an office building or a campus owned by the using organization. The configuration of a LAN can be a star, a ring or; simple devices attached along a length of cable. In LAN, transmission channels used are coaxial or fibre optic cable and special interface units rather than telephone lines and modems. Thus, the transmission speed is very high. The attached computers may be of different types and performing a variety of functions such as data processing, word processing and electronic mail.

Advantages of non-verbal communication:

Complementary: Non-verbal cues complement a verbal message by adding to its meaning. You can pat someone you offended at the back as you say sorry to him or her.

Easy presentation: Information can be easily presented in non-verbal communication through using visual, audio-visual and silent means of non-verbal communication.

Substituting: Non-verbal message may substitute for the verbal message especially if it is blocked by noise, interruption, long distance etc. for example; gestures-finger to lips to indicate need for quite, facial expressions- a nod instead of a yes.

Accenting: Often used to accent a verbal message. Verbal tone indicates the actual meaning of the specific words.

Repeat: Used to repeat the verbal message (e.g. point in a direction while stating directions.)

Disadvantages or limitations of non-verbal communication:

Despite of advantages of non-verbal communication, it is not free from its limitations or disadvantages which are:

Vague and imprecise: Non-verbal communication is quite vague and imprecise. Since in this communication, there is no use of words or language which expresses clear meaning to the receiver. No dictionary can accurately classify them. Their meaning varies not only by culture and context but by the degree of intention.

Continuous: It is possible to stop talking in verbal communication, but it is generally not possible to stop nonverbal cues. Also, spoken language has a structure that makes it easier to tell when a subject has changed, for instance, or to analyze its grammar. Nonverbal does not lend itself to this kind of analysis.

Multi-channel: while watching someone’s eyes, you may miss something significant in a hand gesture. Everything is happening at once and therefore it may be confusing to try to keep up with everything. Most of us simply do not do so, at least not consciously.

A Web application builds on and extends a Web system to add business functionality. In its simplest terms, a Web application is a Web system that allows its users to execute business logic with a Web browser. This is not a very precise definition, but most people’s conception of a Web application is not, either. There is a subtle distinction between a Web application and a Web site.

Malware, or “Malicious Software”, are types of adware or spyware programmed by attackers trying to infect your computer, steal your data, or even gain access to your network. A total of 91.9 million URLs serving malicious code were detected <a href="http://www.securelist.com/en/analysis/204792250/">in the fall of 2012</a>. Malware is a generic term for many different types of “infections” that may be downloaded to your computer.

Phishing is a scam where an attacker uses fake or partial information to try to trick someone into revealing passwords and other confidential information, typically via email or social media. LastPass helps protect you against fake-website phishing attacks by not filling your credentials when it does not see a URL or field match.

Viruses are programs that infect software on your computer. When you run this software, it causes the virus to spread throughout your computer. Basically, the virus can replicate itself and continue spreading to other computers (much like a biological virus), causing hardware and software issues.

Worms are programs that replicate and spread through a network, infecting multiple devices. Unlike a virus, a worm does not need to attach itself to an existing software. Worms cause harm to a network, while viruses cause harm to a targeted computer.

Trojans are software that “appear” genuine, and invites the user to run it, but instead, it releases a malicious load that deletes your files and harms your computer.

A backdoor is a method of bypassing normal authentication to illegally gain remote access to the machine and the data on it. It can be installed to computers by Trojans or worms.
Spyware is a software that gathers a users information without their knowledge, and sends this data to third parties.

KeyLogger software captures the keystrokes entered on your computer keyboard. The keylogger software is then able to transmit these keystrokes where they can be viewed. As a prevention against keyloggers, when using a public or “untrusted” computer, LastPass offers the option to input your master password with a ‘Virtual Keyboard’, allowing you to login without using the keyboard to type your master password.

A database object is any defined object in a database that is used to store or reference data. Some examples of database objects include tables, views, clusters, sequences, indexes, and synonyms. The table is this hour's focus because it is the primary and simplest form of data storage in a relational database. In the Administration Explorer, find and expand the database that you want to create the object in. Right-click a data object type folder and click Create Object . Alternatively, you can right-click a data object folder in the Data Source Explorer and then click Create Object .

An operating system is the most important software that runs on a computer. It manages the computer's memory and processes, as well as all of its software and hardware.
