You left out the options from the CompTIA Network plus exam.
The options are:
Deploy a basic firewall - this would only help increase security and not extend your network
Deploy a router - this would allow you to have a second network with a different subnet, but would not help you extend the network
Deploy a bridge - this would help you join two dissimilar network technologies for the same subnet, but since you cannot run new cable in the area you would not be able to connect more devices
Deploy a wireless access point - this option would allow you to extend your office network without running new cables and address the devices in the existing subnet.
Simply upgrade your network hardware to 100baseT compatible devices and components, eg: Hubs, switches,routers, cables and computers(network cards)
A lower speed network such as a 10BaseT network can handle 1024 devices per segment; that is not the limitation on the entire network.
The Network Layer
100 meters
It is a Network Interface Card that connects 10BaseT Networks together A 10BaseT Cable is an Ethernet Cable consisting of 4 pairs of wires 2 for transmitting and 2 for receiving
RJ45 connectors are used in "ethernet cables". These cables connect network devices between computers and systems.
10BaseT is another name for co-axial cable. It has a maximum cable length of 185 meters or 607 ft.
10baseT networks cords do still exist in 2013. They are considered to be a cheaper alternative to create a LAN network. The flaw in the cord however, is that if there is a small malfunction in part of the cable, then the whole thing will not work.
Network Computing Devices was created in 1987.
10baseT network is based on twisted-pair cables, and is characterized by 10mbit/sec throuhput. Taking into account some overhead (additional control bits), it provides an actual data flow speed of around 0.5 to 1mByte/sec. The maximum distance between two active devices must be less then 100 metres, and it will run on standard Cat3 cabling, using two pairs (of four).
100 Meters per segment, a maximum of 5 segments equaling 500 Meters.
The problem is in the mechanism which is used to connect computers. If you use shared LAN (hubs) it means that if you have 10BaseT connection it will shared among all connected computers. Thus you have 10 Mbps available for all computers together. When you are using 10BaseT switched, it means that each computer in your network will have a separate connection of 10 Mbps.
