What can a MAC address tell you?
MAC Address or media access control address is a unique ID assigned to network interface cards (NICs). It is also known as a physical or hardware address. It identifies the hardware manufacturer and is used for network communication between devices in a network segment.
Why do we need both IP and MAC address?
So again IP Addresses are logical and routeable addresses. … And that’s why computers have both MAC Addresses and IP Addresses. MAC Addresses handle the physical connection from computer to computer while IP Addresses handle the logical routeable connection from both computer to computer AND network to network.
What is the purpose of MAC address?
MAC address is a unique number which is used to track a device in a network. MAC address provides a secure way to find senders or receivers in the network and helps prevent unwanted network access. Mac address is also used in Wi-Fi networks at the airport for a specific device in order to identify it.
What are the major limitations of twisted pair wire explain?
Disadvantages of Twisted Pair Cable
It is incapable carrying a signal over long distances without the use of repeaters only because of high attenuation. It is not suitable for broadband applications only because of its low bandwidth capabilities.
Why more twists are beneficial for LAN cable?
What are some major limitations of twisted pair wire?
What are some major limitations of twisted-pair wire? Twisted pair wire is subject to interference limited in distance bandwidth and data rate.
What are the benefits of getting connected to a network?
Advantages and disadvantages of networks
Files can easily be shared between users. Network users can communicate by email and instant messenger . Security is good – users cannot see other users’ files unlike on stand-alone machines. Data is easy to backup as all the data is stored on the file server .
What are the three types of connections?
About this Strategy Guide

How do network connections work?
Why would you want to connect your computer to a network?
Computer networks help users on the network to share the resources and in communication. … File sharing: Networking of computers helps the network users to share data files. Hardware sharing: Users can share devices such as printers scanners CD-ROM drives hard drives etc.
What are the basic requirements for an Internet connection?
How information is located on the Internet explain?
Most information is found on the Internet by utilizing search engines. A search engine is a web service that uses web robots to query millions of pages on the Internet and creates an index of those web pages. Internet users can then use these services to find information on the Internet.

What is the very first step that should be taken when performing work with a computer?
What is the very first step that should be taken when performing work with a computer? You should power down the system and unplug it.
What connector has 4 pins?
4-pin Fan. The 4-pin Fan power connector is found on motherboards within a computer case. This connector provides power to cooling fans and is typically used on the fan that cools the CPU.
What connector controls the power light?
Types of system panel cables
PLED (Power LED) – The LED power light which indicates when the computer is on off or in Standby. PWRSW (Power SW) – Controls the power button that allows you to turn on and off the computer.
Why are crossover cables important?
Crossover cable enables one to establish a direct connection between two computing devices using Ethernet ports. It Connects two computers directly. You can connect two hubs/switches by using the normal port in both switches and hubs.
What does RJ means in RJ45 connector?
What are modular plugs used for?
The most common uses of modular connectors are for plugging a telephone into the wall outlet (RJ-11) as well as the cable that connects the handset with the phone. They are also the plugs and sockets of RJ-45 Ethernet cables.
Can someone track you by your MAC address?
There isn’t a way to find a stolen computer from the MAC address or to find the identity behind one of these addresses. Much like IP addresses MAC addresses are assigned to network devices and are easy to determine with tools like Command Prompt.
What can hackers do MAC addresses?
Spoofing your MAC address
Each computer and device contains a unique MAC address thus the network administrator can create a black and white list of addresses he or she wants to block or to allow onto the network. This can be used with or without wireless encryption or the hidden network technique.
Can you tell what a device is by its MAC address?
MAC addresses can sometimes be used to identify the maker and potentially model of the device even without the device in hand. This is called the OUI (organizationally unique identifier).
What would happen if two computers had the same IP address and were on the same network and a packet arrived from the Internet?
So what’s going on? For a system to communicate via a network it must have a unique IP address. Conflicts arise when two devices are on the same network trying to use the same IP address. When this occurs both computers end up not being able to connect to network resources or perform other network operations.
