What are the sub components of the computer?
Basically a computer is made up of 6 major components:
PSU - "Power supply unit", which supplies power to the rest of the components.
Motherboard - The connection between all the other major components and where the RAM, GPU and CPU are located.
RAM - "Random access memory", which stores temporary data
GPU - "Graphical processing unit", which feeds your monitor with graphical data
CPU - "Central processing unit", which computes the necessary calculations and is essentially the brain of the computer.
HDD - "Hard-disk drive", is where data is stored more permanently than in the RAM.
How many type of networking cable?
Mainly 5 types of cables are used in computer networking.
1. Twisted pair cable - Twisted pair cabling is a form of wiring in which two conductors (the forward and return conductors of a single circuit) are twisted together for the purposes of canceling out electromagnetic interference (EMI) from external sources; for instance, electromagnetic radiation from unshielded twisted pair (UTP) cables, and crosstalk between neighboring pairs.
2. Optical fiber cable - An optical fiber cable is a cable containing one or more optical fibers. The optical fiber elements are typically individually coated with plastic layers and contained in a protective tube suitable for the environment where the cable will be deployed.
3. Coaxial cable - Coaxial lines confine the electromagnetic wave to the area inside the cable, between the center conductor and the shield. The transmission of energy in the line occurs totally through the dielectric inside the cable between the conductors. Coaxial lines can therefore be bent and twisted (subject to limits) without negative effects, and they can be strapped to conductive supports without inducing unwanted currents in them.
4. Patch cable - A patch cable is an electrical or optical cable, used to connect one electronic or optical device to another for signal routing. Devices of different types (ie: a switch connected to a computer, or switch to router) are connected with patch cords. It is a very fast connection speed. Patch cords are usually produced in many different colors so as to be easily distinguishable, and are relatively short, perhaps no longer than two metres.
5. Ethernet crossover cable - An Ethernet crossover cable is a type of Ethernet cable used to connect computing devices together directly where they would normally be connected via a network switch, hub or router, such as directly connecting two personal computers via their network adapters.

Is windows a good laptop company?
It depends because there are drawbacks to both operating systems. I use both Mac and Windows, so I know about them both. Macs are naturally resilient to viruses, has a very graphical user interface, and although expensive, it will last longer and DOES NOT REQUIRE A WHOLE IT CREW FOR MAINTENANCE. However, YOU CAN'T DO ANYTHING FUN ON A MAC, unless you're playing blizzard games. Windows starts out cheap, and you don't have to hire an IT crew if you don't go to places like malicious porn sites. But you still will have to spend time and money looking for good anti-virus software. So if you plan do only do school stuff, do it on a Mac! If you wanna game or do something else fun, do it on Windows!

Two factors when choosing a computer case?
Size and cooling.
First, don't pick a computer case that is too large for you. Otherwise you'll just take up a lot of space and never use it and it will be harder to move and get around with.
Second, Cooling = Air flow. Make sure there is a good arrangement of fans and air flow in the system. No large ribbon cables obstructing. This also means good construction. Plastic cases insulate heat more then metal cases, bad screws and stamped metal edged are a cut hand away from frustrating you.
As with many things in life, you usually get what you pay for. A good case will cost you a little more but can be used again and again..
Think about it.
