What equipment must your computer have in order to connect to the Internet explain its function?
To connect to the Internet and other computers on a network, a computer must have a NIC (network interface card) installed. A network cable plugged into the NIC on one end and plugged into a cable modem, DSL modem, router, or switch can allow a computer to access the Internet and connect to other computers.
What device is used to test the validity and accuracy of a network cable?
A cable tester is an electronic device used to verify the electrical connections in a signal cable or other wired assembly. Basic cable testers are continuity testers that verify the existence of a conductive path between ends of the cable, and verify the correct wiring of connectors on the cable.
Which statement is not a good practice when working inside a computer?
Immediately after you unplug the computer from the power outlet, you’re safe to begin working inside the case. The motherboard sits on elevated screw holes or spacers to keep it from touching the case. A system always needs the 4-pin auxiliary power connector, and sometimes needs the P1 connector as well.
What are the importance of creating modular jack cable?

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?
Ethernet cable is very low voltage in nature, but the voltage is still present, and the twists in the conductor pairs protect the cable from itself. The twists reverse the polarity of the conductors at each and every twist, and this cancels out differences in their individual electromagnetic fields.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?

How do network connections work?
[1] A computer network is simply a collection of computer equipment that’s connected with wires, optical fibers, or wireless links so the various separate devices (known as nodes) can “talk” to one another and swap data (computerized information).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?
The primary piece of hardware you need is a modem. The type of Internet access you choose will determine the type of modem you need. Dial-up access uses a telephone modem, DSL service uses a DSL modem, cable access uses a cable modem, and satellite service uses a satellite adapter.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.
