Computer networking refers to interconnected computing devices that can exchange data and share resources with each other. These networked devices use a system of rules, called communications protocols, to transmit information over physical or wireless technologies.
Modern networking services connect physically distributed computer networks. These services can optimize network functions through automation and monitoring to create one large-scale, high-performance network. Network services can be scaled up or down based on demand.
All networking solutions come with in-built security features like encryption and access control. Third-party solutions like antivirus software, firewalls, and antimalware can be integrated to make the network more secure.
These services offer solutions for Virtual Private Clouds (VPCs) and for linking on-premise networks with VPCs. Amazon VPC, AWS transit gateway, and AWS private link provide optimized solutions to meet your networking requirements.

Although some employers require a postsecondary certificate or an associate's degree, most require network and computer systems administrators to have a bachelor's degree in a related field, such as computer and information technology. There are degree programs that focus on computer network and system administration. However, because administrators work with computer hardware and equipment, a degree in computer engineering or electrical engineering usually is acceptable as well. Programs in these fields frequently include classes in computer programming, networking, or systems design.

SAN96B-5 leverages proven enterprise-class Gen 5 Fibre Channel technology to deliver outstanding reliability to support nonstop operations for mission-critical workloads. SAN96B-5 utilizes Fabric Vision technology,1 which leverages hardware, FOS and IBM Network Advisor integration to provide advanced functions. It features advanced monitoring, diagnostics, and reliability, availability, and serviceability capabilities to minimize downtime, optimize performance and simplify administration. Moreover, the enterprise-class capabilities of this switch yield a higher performance when compared to 10 Gigabit Ethernet (GbE) storage networking alternatives at a similar cost.
Hyperscale is the ability of an architecture to scale appropriately, as increased demand is added to the system. This solution includes rapid deployment and scaling up or down to meet changes in network security demands. By tightly integrating networking and compute resources in a software-defined system, it is possible to fully utilize all hardware resources available in a clustering solution.
Computer networking is the branch of computer science that deals with the ideation, architecture, creation, maintenance, and security of computer networks. It is a combination of computer science, computer engineering, and telecommunication.
Advancements in the technology of digital telecommunications have led to the development of embedded networking, a practice that expands the range of potential applications for embedded systems in a variety of contexts. The field of embedded networking deals with the network design and topology, hardware devices, and communication/data exchange protocols needed to connect and exchange information between embedded systems.
Embedded systems engineers today have access to a range of wired and wireless communication options for implementing networking capabilities into their embedded systems. Effective design of an embedded networking product requires the selection of a protocol stack that enables the desired networking features and communication patterns while managing design constraints such as memory and power consumption. Embedded systems form the basis for the Internet of Things (IoT), networks of devices whose capabilities depend on internet connectivity.
For engineers that may be new to building networked embedded systems, we offer this basic embedded networking introduction. We'll look at several implementation models for embedded networks and show you how the most common embedded systems have implemented networking to support critical functions and applications in real-world settings.
Our discussion of embedded networking begins with an overview of computer networking systems and how they function. The earliest conceptual model of computer networks was developed by the International Organization for Standardization (ISO) in 1984 and is known as the Open System Interconnection (OSI) model.
The OSI model itself is conceptual in nature - it does not include any actual specifications for network implementation. However, the OSI model does provide a framework for understanding the components of a complete network communication system. As we will see, many of today's most commonly implemented networking technologies use features and protocols that reflect parts of the OSI model.
With the OSI model as a basis, embedded systems engineers have several options for how to implement networking for their embedded devices. Networked systems are designed based on specific application needs and constraints such as cost, power consumption, and memory. Not all embedded systems require all of the functionalities that are expressed in the OSI - it is up to embedded engineers to determine which features are required and to implement suitable protocols from the required layers.
The specifications for the CAN bus protocol are described in the international standard ISO 11898:2003. The specification includes requirements for the physical layer and data link layers of the network, leaving individual engineers or manufacturers to implement other high-level protocols of their choosing to satisfy additional networking requirements.
Embedded networking presents a unique challenge for engineers, whether the application entails networking microcontrollers with each other in a closed system or implementing a physical ethernet connection to support LAN, WAN, or internet connectivity. To succeed, developers must be familiar with the basic functioning of computer networks and effectively adapt this knowledge to account for the application-specific device requirements and limitations associated with their embedded system. 041b061a72
