Network-Attached Storage (NAS)
Network-attached storage (NAS) is a type of dedicated file storage device that provides local-area network local area network (LAN) nodes with file-based shared storagethrough a standard Ethernet connection.
NAS devices, which typically do not have a keyboard or display, are configured and managed with a browser-based utility program. Each NAS resides on the LAN as an independent network node and has its own IP address.

What is wireless broadband (WiBB)?
wireless broadband (WiBB): Wireless broadband is high-speed Internet and data service delivered through a wireless local area network (WLAN) or wide area network (WWAN).
As with other wireless service, wireless broadband may be either fixed or mobile. A fixed wireless service provides wireless Internet for devices in relatively permanent locations, such as homes and offices. Fixed wireless broadband technologies include LMDS...

4G (fourth-generation wireless)
4G is the short name for fourth-generation wireless, the stage of broadband mobile communications that will supercede the third generation (3G ).
Carriers that use orthogonal frequency-division multiplexing (OFDM) instead of time division multiple access (TDMA) or code division multiple access (CDMA) are increasingly marketing their services as being 4G, even when their data speeds are not as fast as the International Telecommunication Union (ITU) specifies....

5G Definintion
5G is the coming fifth-generation wireless broadband technology based on the IEEE802.11ac standard.
5G will provide better speeds and coverage than the current 4G. 5G operates with a 5Ghz signal and is set to offer speeds of up to 1 Gb/s for tens of connections or tens of Mb/s for tens of thousands of connections. Huawei, a major player in the Chinese mobile market, believes 5G will provide speeds 100x faster than 4G LTE offers. 5G also increases network expandability up ...

What’s the Difference Between a CPU and a GPU?
What’s the Difference Between a CPU and a GPU?
The CPU (central processing unit) has often been called the brains of the PC. But increasingly, that brain is being enhanced by another part of the PC – the GPU (graphics processing unit), which is its soul.
All PCs have chips that render the display images to monitors. But not all these chips are created equal. Intel’s integrated graphics controller provides basic graphics that can display only productivity applications like Microsoft PowerPoin...

GPU Definition
GPU Definition
Stands for "Graphics Processing Unit." A GPU is a processor designed to handle graphics operations. This includes both 2D and 3D calculations, though GPUs primarily excel at rendering 3D graphics.
History
Early PCs did not include GPUs, which meant the CPU had to handle all standard calculations and graphics operations. As software demands increased and graphics became more important (especially in video games), a need arose for a separate processor to render graphics. On A...

FTP (File Transfer Protocol)
FTP (File Transfer Protocol)
FTP (File Transfer Protocol): FTP is an acronym for File Transfer Protocol. As the name suggests, FTP is used to transfer files between computers on a network. You can use FTP to exchange files between computer accounts, transfer files between an account and a desktop computer, or access online software archives. Keep in mind, however, that many FTP sites are heavily used and require several attempts before connecting.

DSL (Digital Subscriber Line)
DSL (Digital Subscriber Line)
DSL (Digital Subscriber Line) is a technology for bringing high- bandwidth information to homes and small businesses over ordinary copper telephone lines. xDSL refers to different variations of DSL, such as ADSL, HDSL, and RADSL. Assuming your home or small business is close enough to a telephone company central office that offers DSL service, you may be able to receive data at rates up to 6.1 megabits (millions of bits) per second (of a theoretical 8.448 megabit...

Video On Demand (VoD)
Video On Demand (VoD)
Video on demand (VoD) is an interactive TV technology that allows subscribers to view programming in real time or download programs and view them later. A VoD system at the consumer level can consist of a standard TV receiver along with a set-top box. Alternatively, the service can be delivered over the Internet to home computers, portable computers, high-end cellular telephone sets and advanced digital media devices.
VoD has historically suffered from a lack of avail...

Recovery Time Objective (RTO)
Recovery Time Objective (RTO)
The recovery time objective (RTO) is the maximum tolerable length of time that a computer, system, network, or application can be down after a failure or disaster occurs.
The RTO is a function of the extent to which the interruption disrupts normal operations and the amount of revenue lost per unit time as a result of the disaster. These factors in turn depend on the affected equipment and application(s). An RTO is measured in seconds, minutes, hours, or days ...
