They are usually located in a LAN like a home or on the internet. Lab 2.1 Review 1. A network device is equipment used to connect two or more computers together, such as a router, network cable, and network cards. A peripheral device is any external device on a computer such as a mouse, keyboard, or a monitor. 2.
Voice or data computers, network interfaces, and transmission medium C. Modems, transmission links, and wireless access points D. TCP/IP software, modems, and transmission links Correct! The correct answer is: B. âA network consists of two or more connected computersâ (Laudon & Laudon, 2011, p. 194). âBasic network components include computers, network interfaces, a connection medium, network operating system software, and either a hub or a switchâ (p. 225). Networking and telecommunications technology, consisting of both physical devices and software, links the various pieces of hardware and transfers data from one physical location to another. 2.
A local application is a program such as a word processor or a spread sheet that is stored on a local computer and runs only on that local computer. A network application is one that is designed to run over a network such as the internet, or a small or large network of connected computers, it has two components one that runs on the local computer and one that runs on a network computer such as email. 4. [pic] 5. List the six common types of computers available.
IIS 7 provides the basic Web server functionality that enables you to publish a standard Website on the Internet or on a private network. 2. The activities performed for network clients by a Windows Server 2008 are known as __________. A. services B. roles C. domains D. functions
Client server Client server is when there is more than one computer is in a network with a server where all information comes through from. For example if there are 2 computers, computer number 1 and computer number 2. Let say computer number 1 is the client who requests service from the computer
NT1210 Research Paper From what I gathered about “Layer 2 switches” is that the Layer 2 switches use a MAC address from a host NIC card. This makes it to decide where to “forward frames”. Also Layer 2 is a hardware-based control. It uses “application-specific integrated circuits”, which provides “wire speed, high speed, low latency”. OIS layer 7 packets are called “layer 4-7 switches” these are like content switches, content service switches and web switches or application switches… Content switches are normally used for “load balancing” among server groups like on TCP/IP.
This link is above the Physical layer it is responsible for end-to-end validity of what is being transmitted. Datalink layer is divided into; two sub-layer which is Media Access Control (MAC) that determines the physical addressing of the host. The MAC addresses (physical device addresses) that communicate with other devices within the network. Then there is the Logical Link Control (LLC) sub layer. What it is responsible for is the synchronizing frames, error checking, and the flow control.
The relationships that must be considered are: • Objects – This can be files, printers, computers, and other resources. • Access Tokens – the access token is used to verify access to the ACE for the object. Access Tokens are recreated at each log-on. • Access Control List (ACL) /Access Control Entries (ACE) – ACL is a table that indicates the access rights a user has access to as it relates to a particular object. ACE are each input of the ACL.

Computer Class IFSM 201 1. Design a wireless network for your home network. A. What is network? “A network consists of two or more computers that are linked together to share resources (such as printers and CDs), exchange files, or allow electronic communications.
