As you all know–AKA Mr. McDonald AKA my Advanced Computers teacher AKA my only viewer (heyyyy)–this school year is the year of blogging! Students were taught to create their own blog site with the help of WordPress.com. Blogs are due throughout the year and lucky for me this first mandatory one is already one-thirds complete. The main focus of this blog is the motherboard, the CPU, memory, and binary. To those who don’t know me I am no computer geek or genius, but I do know a thing or two.
The motherboard holds all the good stuff. You know like the CPU (we’ll get to that), internal and external buses, expansion slots, memory slots, chipset, BIOS chip, ports and connectors,
external cache, etc. In short, the motherboard contains all the components that is essential to the functioning of a computer. Now when you hear the term “form factor” do not be afraid. Motherboards come in various shapes and sizes. Some form factors are the AT, Baby AT, ATX, Mirco ATX, NLX, and BTX. These are all motherboards, however, the components are arranged differently.
The motherboard may be where the components live, but let us raise our hats to the brain of the computer: The CPU also known as the Central Processing Unit. The CPU is made up of the Control Unit (CU), Arithmetic Logic Unit (ALU), and cache memory (pronounced cash $$$ not cashee). A heatsink or fan is needed in cooling down the CPU, without a cooling device the CPU would overheat. After all it is doing a lot of work, of course it would break a sweat!
The two basic types of PC memory is read-only memory (ROM) and random access memory (RAM). The difference between ROM and RAM is that ROM is used for the CPU cache and BIOS chip while RAM is used for system memory and CPU registers. ROM is also non-volatile storage meaning that is does not need power in order to save or store data. RAM, on the other hand, is volatile meaning that it requires power to preserve data.
0011! 0010!! 0001!!! Go! Yes, I did just count down in binary. Binary code is simply the computer’s language. Computers communicate using the base 2 system that breaks everything down into basic 0’s and 1’s.
