Cloud Computing

What is Cloud Computing?

Cloud computing is a general term for anything that involves storing data, accessing data and programs over the internet instead of your computer’s hard drive. It is usually classified on the basis of location or on the service that the cloud is offering. The name “cloud computing” that often used to represent the Internet in flowcharts and diagrams.

Cloud Computing Based on Service

The four categories of cloud computing based on service are such as Infrastructure as a service (IaaS), Platform as a service (PaaS), Software as a service (SaaS), and Function as a service (FaaS). These are also called the cloud computing stack because they on top of one another.

Cloud Computing Based on Location

The four types of cloud computing based on location are such as public cloud, private cloud, hybrid cloud, and community cloud. They are compare to provide different levels of security and management requirements, it will depend on which type of data you are working with.

Interconnecting Devices

Interconnecting Devices An Interconnecting devices is a network device. It used to transfer data from one computer to other computer with the help of network devices. There are five categories of interconnecting devices are such as. Router Hubs Switches/Bridge Repeater BRouter Repeater: Now I am going to tell you the repeater is an electronic device that used to receive and send a signal. It amplifies the signal and noise. It provides transmission of the signal. HUB (Hyper User Bus): In this, it used to link several computers in the same network. It based on broadcasting, and it sends the data to all computers and repeats the signal which receives a signal from one port and copies to other port and traffic are high. Bridge / Switch: In this, we can see the interconnecting devices which can divide a single network into two or more segment are called Bridge / Switch. It has multiple ports like 2, 4, 16, and 32. The Switch main...

Printer

What is Printer? Another widely used output device is a printer and it is a computer peripheral device. A printer produces a hard copy of a processed text or a result. A hard copy refers to a permanent human-readable text or graphics taken on physical print media such as paper or transparency. A printer will use toner to provide a quality print on paper, a toner is a replaceable material. Once the toner gets empty we can refill it and reuse it.

CMOS

What is CMOS? CMOS stands for Complimentary Metal Oxide Semi-Conductor and it stores roughly 64Kb of data. It is the part of the southbridge in most computers. The specification stored in Complimentary Metal Oxide Semi-Conductor must match hardware and it allows you to access the BIOS. When hardware is change or update, Complimentary Metal Oxide Semi-Conductor must be updated. CMOS Battery Accessing BIOS through CMOS setup Complimentary Metal Oxide Semi-Conductor can only be accessed when the PC is booting and key combination at start-up. The changes are stores on an NVRAM Complimentary Metal Oxide Semi-Conductor chip. The mouse doesn’t work in Complimentary Metal Oxide Semi-Conductor setup. AMI and AWARD BIOS – DEL key PHOENIX BIOS – CTRL, ALT and ESC keys or F2 CMOS Chip Complimentary Metal Oxide Semi-Conductor is stored in an SRAM chip called Non-Volatile Random Access Memory (NVRAM). It stores data that is uses by the BIOS and NVRAM is powered by Com...
