Devices for Network Connection
3G/4G -
3G generation mobile communications is a generation of standards for mobile phones and mobile communication services can be used over the whole world with international mobile communications.
4G -
Is the fourth generation. It is a successor to the 3G and 2G. A 4G system is expected to provide a secure IP based mobile broadband laptop computer wireless modems, smart phones, and other mobile devices.
Wireless/Bluetooth -
Bluetooth is a open wireless technology standard for exchanging data over short distances.
Wireless -
Wireless is the transfer of information between two or more points that are physically not connected. Distances can be short, as a few meters or long ranging from thousands to millions of kilometres.
Network Interface Cards (NIC) -

Network Interface Cards (NIC) -
A network interface card is a computer hardware component that connects a computer to a computer network. Most Network interface cards are designed for a particular type of network, media, although some can serve multiple networks.
Different Types of Computer Systems
PC -
A personal computer (PC) is any general-purpose computer. Size, capabilities, it useful for individuals,expensive mainframe systems to be used by many people, usually at the same time. Large data processing systems.
Laptop -
A laptop, is a portable computer most of the typical components of a desktop computer, are included in a laptop including a display, a keyboard, a pointing device and speakers. A laptop is powered by mains electricity via an AC adapter, and can be used away from an outlet using a rechargeable battery.
Netbook -
Netbooks are a category of small, lightweight, and inexpensive laptop computers.Netbooks are smaller and more portable - the screen size ranges from 7 inches to 10 inches - they tend to use lower power such as the Intel Atom in order to maximize battery life. They don't have a cd/dvd player they are intended for light computer work such as browsing the web, cloud computing checking email,word processing - they aren't that good at doing heavy video editing or photographic work.
PDA (Personal digital assistant) -
A personal digital assistant (PDA), also known as a personal data assistant, is a mobile device that functions as a personal information manager. Current PDAs often have the ability to connect to the Internet. A PDA has an electronic visual display, enabling it to include a web browser, but some newer models also have audio, enabling them to be used as mobile phones or portable media players. Many PDAs can access the Internet, or via Wi-Fi or Wireless Networks. Also Many PDAs use touchscreen technology.
Mobile phone -
A mobile phone also known as a cell phone allows phone calls to another mobile phone or text messages wherever they are. Early mobile phones were usually bulky they provided limited service because only a few networks were available. Modern mobile phones make use of the network, where networks are re-used repeatedly.
A video game console is an interactive entertainment computer system that produces a video display which can be used with a display device (a television, monitor, etc.)
To display the video game.
Tablet -
A tablet personal computer or tablet PC is a tablet-sized computer it also has key features of a full-size personal computer has. A tablet PC is essentially a small laptop computer, equipped with a rotatable touchscreen aan additional input device, and also has a standard PC operating system like Windows or Linux.
Server -
A server is a computer program running to serve the requests of other programs,the server performs .The clients either run on the same computer or connect through the network. In most common use, server is a physical computer hardware system dedicated to running one or more such services to serve the needs of users of the other computers on the network.

Keyboard (Input) -
In computing, a keyboard is a typewriter-style keyboard, which uses an arrangement of buttons or keys, It very mechanical with all it letters and numbers on it with also all it command buttons as well at spaced in one place.
Scanner (Input) -
In computing, an image scanner—often abbreviated to just scanner—is a device that optically scans images, printed text, and converts it to a digital image. In computing, an image scanner—often abbreviated to just scanner—is a device that optically scans images, and converts it to a digital image.
Microphone (Input) -
A microphone called a mic is very common to people nowadays. Especially singer’s and also for computer’s too because it an input device. For example Skype is very common with microphone’s because people can hear and talk to each other.

Storage Devices
A data storage device is a device for storing information (data). A storage device may hold information, process information, or both. USB devices, floppy discs all are portable devices.
Zip Disk -
Flash Drive -
A Flash Drive is a small, portable flash memory card that plugs into a computer USB port and functions as a portable hard drive. USB flash drives have less storage capacity than an external hard drive, but they are smaller and more durable.
Floppy Disk -
A floppy disk is a soft magnetic disk.Unlike most hard disks, floppy disks are portable, because you can remove them from a disk drive. Disk drives for floppy disks are called floppy drives. Floppy disks are slower to access than hard disks and have less storage capacity and they are much less expensive.
A high-capacity floppy disk drive. Zip disks are slightly larger than conventional floppy disks, and about twice as thick. They can hold 100 or 250 MB of data. Because they're relatively inexpensive and durable, they have become a popular media for backing up hard disks and for transporting large files.
Cd -
Cd is a type of CD disk that enables you to write onto it in multiple sessions. One of the problems with CD-R disks is that you can only write to them once. With CD-RW drives and disks, you can treat the optical disk just like a floppy or hard disk, writing data onto it multiple times.
Removable Hardware drive -
Is a type of disk drive system. Removable disk drives combine the best aspects of hard and floppy disks. They are nearly as capacious and fast as hard disks and have the portability of floppy disks. Their biggest drawback is that they're relatively expensive.
Memory Stick -
The Memory Stick digital data storage is designed to become a standard storage and transfer media. The 8MB Memory Stick has a minimum of five times the storage capacity of a standard 3.5 inch floppy disk. It is available in 4MB, 8MB, 16MB, 32MB, 64MB, and 128MB storage sizes. 
Micro Drive -
A microdrive is an extremely small hard disk that can fit in a CompactCard memory slot, enabling digital cameras designed to use CompactFlash memory cards to gain larger storage.
Hardware Components
Processor -
The central processing unit (CPU) is the part of a computer system that carries out the instructions of a computer program. The CPU plays a role that is very important to the brain in the computer.
Memory -
In computing, memory refers to the physical devices used to store programs, data on a temporary or permanent basis for use in a computer or other digital electronic device. The term primary memory is used for the information in physical systems which are fast.
