embedded system
An embedded system is a programmed controlling
and operating system with a dedicated function within a larger mechanical or electrical system, often with real-time computing constraints. It is embedded as part of a complete device often including hardware and mechanical parts.
What are examples of dedicated computers?
Dedicated [special purpose] computer – is built to handle a specific task, it can perform that task only and no other. Thus we can find a variety of dedicated computers performing a wide variety of tasks For example an ATM, digital camera, mobile phone, washing machine, video games, autopilots etc.
What is a dedicated computer to provide service for client?
A server is a physical computer dedicated to run services to serve the needs of other computers. Depending on the service that is running, it could be a file server, database server, home media server, print server, or web server.
What is the difference between multi purpose computers and dedicated computers?
A dedicated computer would be something like a server. For example if you have a file server, its purpose is to store and share files across the network. A general purpose computer would be something like your personal computer. , an aircraft’s automatic pilot is an example for dedicated computer.
Is an ATM an example of a dedicated device?
A Brief History, Overview & Definition Common examples are ATMs, POS terminals, and airport ticket vending machines. A dedicated device by definition is an enterprise hardware unit built for a single purpose.
What is the main difference between a dedicated device and a computer?
Computers are an example of machines that can do a variety of procedures, or algorithms. They are an example of a programmable device. A dedicated device is something that is built or programmed to do only a specific procedure, or algorithm.
What is a multi purpose computer?
A personal computer [PC] is a multi-purpose computer whose size, capabilities, and price make it feasible for individual use. Software for personal computers is typically developed and distributed independently from the hardware or operating system manufacturers.
Which device is used for single purpose?
Single purpose devices were earlier manufactured specifically for certain business purposes. Historically, an electric drill or a crane are also classic examples of single-purpose devices. With the advent of computational operations, computers and single-purpose devices were always manufactured and used separately.
Whats Does client mean?
noun. a person or group that uses the professional advice or services of a lawyer, accountant, advertising agency, architect, etc. a person who is receiving the benefits, services, etc., of a social welfare agency, a government bureau, etc. a customer. anyone under the patronage of another; a dependent.
What are the three steps in any computer system?
The three stages of computing are input, processing and output. A computer works through these stages by ‘running’ a program.
What is purpose of device?
A device is a unit of physical hardware or equipment that provides one or more computing functions within a computer system. It can provide input to the computer, accept output or both. A device can be any electronic element with some computing ability that supports the installation of firmware or third-party software.
Is a smartphone a dedicated device?
Core Characteristics. Dedicated devices are not like smartphones, which we use for multiple tasks at any given time. Instead, dedicated devices have a very specific set of functions; these are described below: Used for a single use case.
What is an example of client?
The definition of a client means a customer or a person who uses services. An example of a client is a student being tutored at a college writing center. One that depends on the protection of another. See also architecture, client/server, and server.
A network consists of two or more computers that are linked in order to share resources [such as printers and CDs], exchange files, or allow electronic communications. The computers on a network may be linked through cables, telephone lines, radio waves, satellites, or infrared light beams.
Two very common types of networks include:
- Local Area Network [LAN]
- Wide Area Network [WAN]
You may also see references to a Metropolitan Area Networks [MAN], a Wireless LAN [WLAN], or a Wireless WAN [WWAN].
Local Area Network
A Local Area Network [LAN] is a network that is confined to a relatively small area. It is generally limited to a geographic area such as a writing lab, school, or building.
Computers connected to a network are broadly categorized as servers or workstations. Servers are generally not used by humans directly, but rather run continuously to provide "services" to the other computers [and their human users] on the network. Services provided can include printing and faxing, software hosting, file storage and sharing, messaging, data storage and retrieval, complete access control [security] for the network's resources, and many others.
Workstations are called such because they typically do have a human user which interacts with the network through them. Workstations were traditionally considered a desktop, consisting of a computer, keyboard, display, and mouse, or a laptop, with with integrated keyboard, display, and touchpad. With the advent of the tablet computer, and the touch screen devices such as iPad and iPhone, our definition of workstation is quickly evolving to include those devices, because of their ability to interact with the network and utilize network services.
Servers tend to be more powerful than workstations, although configurations are guided by needs. For example, a group of servers might be located in a secure area, away from humans, and only accessed through the network. In such cases, it would be common for the servers to operate without a dedicated display or keyboard. However, the size and speed of the server's processor[s], hard drive, and main memory might add dramatically to the cost of the system. On the other hand, a workstation might not need as much storage or working memory, but might require an expensive display to accommodate the needs of its user. Every computer on a network should be appropriately configured for its use.
On a single LAN, computers and servers may be connected by cables or wirelessly. Wireless access to a wired network is made possible by wireless access points [WAPs]. These WAP devices provide a bridge between computers and networks. A typical WAP might have the theoretical capacity to connect hundreds or even thousands of wireless users to a network, although practical capacity might be far less.
Nearly always servers will be connected by cables to the network, because the cable connections remain the fastest. Workstations which are stationary [desktops] are also usually connected by a cable to the network, although the cost of wireless adapters has dropped to the point that, when installing workstations in an existing facility with inadequate wiring, it can be easier and less expensive to use wireless for a desktop.
See the Topology, Cabling, and Hardware sections of this tutorial for more information on the configuration of a LAN.
Wide Area Network
Wide Area Networks [WANs] connect networks in larger geographic areas, such as Florida, the United States, or the world. Dedicated transoceanic cabling or satellite uplinks may be used to connect this type of global network.
Using a WAN, schools in Florida can communicate with places like Tokyo in a matter of seconds, without paying enormous phone bills. Two users a half-world apart with workstations equipped with microphones and a webcams might teleconference in real time. A WAN is complicated. It uses multiplexers, bridges, and routers to connect local and metropolitan networks to global communications networks like the Internet. To users, however, a WAN will not appear to be much different than a LAN.
