Computer Networking
Computer networks are collections of computers which are connected together in order to communicate and transfer information. Questions about computer networks, networking protocols, and how to set them up belong here.

Local area networks allow computers to be connected together to share services, peripherals and to allow control of groups of machines.
Where are firewalls commonly placed in private network?
Between the server / router and the internet router.

What does AYD mean in ping ayd?
Ping has many models and styles of putters one of the models encompass the use of the word "DAY" their is the" Day" / "My Day" / and the "AYD" just a variation to distinguish the 3 different models with a play on the words hence AYD is a DAY respelled to name the putter with the unique design with the subtle difference in that series. Hope this helps.
ya if they are on both side then.. if one side then not..
Which one of the following provides the foundation for DoD's Green Procurement Program?
Resource Conservation and Recovery Act
Which of these options are characteristics of the Ethernet data transmission standard?
Data transmissions is via frames, each having a single MAC address.
The CSMA/CD access method is used to detect collisions.
What is the pupose of the command ping 127.0.0.1?
The purpose of the command is to send a ping request to the IP address 127.0.0.1. The IP should respond with a "pong" if it accessible. As the address 127.0.0.1 is the originator of the ping request, it should always respond unless something is wrong with the TCP/IP stack.
What information does the tracert command give that the ping commands does not?
Tracert lists the places that a message passes from source to destination. Ping only says the computer destination is answering "yes, I'm here."
A digital multimedia receiver (DMR) or digital media adapter (DMA) is a home entertainment device that can connect to a home network to retrieve digital media files (such as music, pictures, or video) from a personal computer ( or other media server and play it back on home theater system or TV.
What is attached inside the computer so that it can participate in the network?
A Network Interface Card (NIC) is a hardware device that handles an interface to a computer network and allows a network-capable device to access that network. It is a computer hardware component designed to allow computers to communicate over a computer network.
What are the loopback addresses in IPv4 and IPv6?
In IPv4, the loopback address is 127.0.0.1. In IPv6 it is ::1.
A link test just confirms that there is voltage on wires 1,2,3, and 6. The active wires in the cable.
Is a game controller an input or output device?
It's an input device. The Computer Monitors the activity on the controller - and, depending on what the player does with it - moves a character on the screen etc.
What type of cable would you use to connect a pc nic to an rj45 Ethernet port of a cisco router?
cat 5 Ethernet cable
OLE DB (Object Linking and Embedding, Database, sometimes written as OLEDB or OLE-DB) is an API designed by Microsoft for accessing data from a variety of sources in a uniform manner. It is a set of interfaces implemented using the Component Object Model (COM); it is otherwise unrelated to OLE. It was designed as a higher-level replacement for, and successor to, ODBC, extending its feature set to support a wider variety of non-relational databases, such as object databases and spreadsheets that do not necessarily implement SQL.
OLE DB separates the data store from the application that needs access to it through a set of abstractions that include the datasource, session, command and rowsets. This was done because different applications need access to different types and sources of data and do not necessarily want to know how to access functionality with technology-specific methods. OLE DB is conceptually divided into consumers and providers. The consumers are the applications that need access to the data, and the provider is the software component that implements the interface and therefore provides the data to the consumer. OLE DB is part of the Microsoft Data Access Components (MDAC) stack. MDAC is a group of Microsoft technologies that interact together as a framework that allows programmers a uniform and comprehensive way of developing applications for accessing almost any data store. OLE DB providers can be created to access such simple data stores as a text file and spreadsheet, through to such complex databases as Oracle, SQL Server and Sybase ASE. It can also provide access to hierarchical datastores such as email systems.
However, because different data store technologies can have different capabilities, OLE DB providers may not implement every possible interface available to OLE DB. The capabilities that are available are implemented through the use of COM objects - an OLE DB provider will map the data store technologies functionality to a particular COM interface. Microsoft describes the availability of an interface as "provider-specific," as it may not be applicable depending on the database technology involved. Note also that providers may augment the capabilities of a data store - these capabilities are known as services in Microsoft parlance.
Network topology can be defined as the way in which different computers are interconnected with the help of some specific media.
