Explain what is the subnet id of host 86.212.118.145 given a subnet mask 255.0.0.0?
You must extract the first 8 bits of the host address (since the subnet mask has the first 8 bits equal to 1), and set all others to zero. The answer in this case is 86.0.0.0.

Who is connected to my wireless network?
You should be able to check how many computers are connected to your router, in the router settings. Most likely you can find it in "Status" for wireless network or for all networks. You check MAC addresses for all your computers connected to the router and compare it with those in the list. In that way you know if you have some "guests". You find out who connected to your router will be much harder and require special software and training.
PS: you can use MAC filter to block "guests".
Basic operation of collision detection in Ethernet?
The basic operation of collision detection in Ethernet is to allow any station to send a packet whenever it is ready. This transmission is known as unslotted ALOHA.

Does a computer network keep records of items sold?
A computer network can keep records of items sold if it includes software that has that as its function but that's not automatic. To take an analogy - a cash register can ring up the price of items sold but unless you have some paper tape in it (or have it connected to some software that is storing that information), you won't have any permanent record of the items sold.
These systems are referred to as EPOS (Electronic Points of Sale). Employed by retails more and more now they are a database system which is programmed to keep inventory and financial data and reports on either. The system employees a Back office computer connected to one of more "cash registers" or "Terminals". The use of bar-codes is also employed to allow unique data for each product line to have price, description tax and a range of other required data attached to that code. The terminal will collate the items sold. Subtotal the cost and accept payment when totalled off by the operator. When totalled off the systems communicates the financial data back to the office system (financial reporting) This is collated by terminal and per trading day/week/month and even year. The items sold are removed from the Inventory system (the virtual warehouse) and this is again collated for real time sales, end of day, week, month and can even be used to ascertain seasonal changes in sales patterns. Further to this the data can be reported on and used ti create an order to replace the sold stock. Such reports can be undertaken at the site or passed to a "buying department" where multiple stores will have their orders for replenishment undertaken by a "buyer". This type of report is vital to multi-national retailers who can use this to inform their buying power with a supplier and ultimately push for a lower cost price to that retailer.
When connecting a LAN cable to a tower case what connector do you place in it?
RJ-45 Black also known as the ethernet port
You sure didn't give much to go on here. OSD typically stands for on screen display. OSD timeout logically would mean that the information has been on the screen too long without any changes. You see this a lot in dealing with financial data.
What problems could eventuate if a network is not well managed?
Well for starters the network would be unusable if not well managed many bugs and glitches could arise as well, the speed of the network turn slow ect
Can computer monitors make eyes sore and itchy?
About 7 years ago I had problems with my eyes that had grown so big I was unable to work in front of a computer screen more than 10 minutes at a time. My eyes would simply explode and all the white in them would become red. Then that happened my eyes would also become sore. It had become a vicious circle and at the time many eyes doctors were clueless and had failed to read up on common symptoms among IT people who work many hours each day behind a computer. Luckily I finally found an eye doctor that was of some help, and managed through experimentation to get my red eyesproblem under control.
- Get your eyesight checked. Glasses can help reduce eyestrain "work stress" on eye muscles.
- Try massage and relax the muscles around your eyes once in a while.
- Get checked for obvious allergies. Whether it is pollen or something else.

What is the value of network addresses?
A network address is like a street address; if you want to receive your mail from the post office then the postal worker needs a way to identify where you live.
Networks are the same way; they need a way to identify each network and each device in a network to send and receive messages.
It is a digital communication network that groups all transmitted data irrespective of content, type or structure into suitable-sized blocks called packets.
The principal goal of packet switching is to optimize utilization of available link capacity, minimize response time, and increase robustness of communication.
