I can detail you on the basics but the really detailed things you might want to take classes for those.

A computer is usually composed of (From most to least important):
1) Motherboard (The biggest board you see when you open up a computer)
2) Microprocessor (CPU)
3) Memory (RAM-Random Access Memory)
4) Video Card
5) Hard Drive
6) Sound Card
7) Optical Drives (CD/DVD)
8) Floppy Drives

1) Motherboard is the biggest circuit board you will find in any computer available in today's markets. Everything you have in your computer plugs into the motherboard. The motherboard contains 2 important elements: the north and south bridge controllers. North Bridge is represented usually by a big aluminum type heatsink in the middle of the motherboard, it controlls the interactions between the CPU, RAM, and the Video card. South Bridge is another controller that sits to the lower right of the North Bridge and is also represented by a smaller aluminum heatsink and it controlls everything else in the computer.

2) Microprocessor is the brain your computer, everything that is excuted goes through the CPU. You can identify the CPU on the motherboard by locating a baseball size heatsink, under the big heatsink is the processor chip itself.

3) RAM is the "paper sticks" that sits close to the edge of the motherboard and is the workload behind the computer. The amount of RAM tells you how much programs can the computer run simuteanously.

4) A video card is like the eyes of the computer, it displays everything you see on a monitor. Video cards comes in 2 ways, integrated and stand alone cards. Integrated video means the video chip itself is integrated or built into the motherboard and therefore using up a portion of system resources. Stand alone video cards are sold in stores everywhere, you plug them in horizontally in a AGP or PCI-Express slot.

5)Hard drive is where everything is kept, your operating system (Windows XP), all your settings, files, etc. The hard drive IS the slowest element in a typical computer.

6) Sound card is of course responsible for producing sound. It comes in 2 ways like a video card does, integrated and stand alone.

7) An optical drive is your Cd or DVD drive, it loads removable media discs. A typical CD holds about 700MB, and a DVD holds about 4.7GB.

8) Floppy drive is a type of removable storage device that holds about 1.44Mb. It is not reliable and should not be depended on.

While the technologies used in computers have changed dramatically since the first electronic, general-purpose computers of the 1940s, most still use the stored program architecture (sometimes called the von Neumann architecture). The design made the universal computer a practical reality.

The architecture describes a computer with four main sections: the arithmetic and logic unit (ALU), the control circuitry, the memory, and the input and output devices (collectively termed I/O). These parts are interconnected by bundles of wires (called "buses" when the same bundle supports more than one data path) and are usually driven by a timer or clock (although other events could drive the control circuitry).

Conceptually, a computer's memory can be viewed as a list of cells. Each cell has a numbered "address" and can store a small, fixed amount of information. This information can either be an instruction, telling the computer what to do, or data, the information which the computer is to process using the instructions that have been placed in the memory. In principle, any cell can be used to store either instructions or data.

The ALU is in many senses the heart of the computer. It is capable of performing two classes of basic operations. The first is arithmetic operations; for instance, adding or subtracting two numbers together. The set of arithmetic operations may be very limited; indeed, some designs do not directly support multiplication and division operations (instead, users support multiplication and division through programs that perform multiple additions, subtractions, and other digit manipulations). The second class of ALU operations involves comparison operations: given two numbers, determining if they are equal, or if not equal which is larger.

The I/O systems are the means by which the computer receives information from the outside world, and reports its results back to that world. On a typical personal computer, input devices include objects like the keyboard and mouse, and output devices include computer monitors, printers and the like, but as will be discussed later a huge variety of devices can be connected to a computer and serve as I/O devices.

The control system ties this all together. Its job is to read instructions and data from memory or the I/O devices, decode the instructions, providing the ALU with the correct inputs according to the instructions, "tell" the ALU what operation to perform on those inputs, and send the results back to the memory or to the I/O devices. One key component of the control system is a counter that keeps track of what the address of the current instruction is; typically, this is incremented each time an instruction is executed, unless the instruction itself indicates that the next instruction should be at some other location (allowing the computer to repeatedly execute the same instructions).

Since the 1980s the ALU and control unit (collectively called a central processing unit or CPU) have typically been located on a single integrated circuit called a microprocessor.

The functioning of such a computer is in principle quite straightforward. Typically, on each clock cycle, the computer fetches instructions and data from its memory. The instructions are executed, the results are stored, and the next instruction is fetched. This procedure repeats until a halt instruction is encountered.

The set of instructions interpreted by the control unit, and executed by the ALU, are limited in number, precisely defined, and very simple operations. Broadly, they fit into one or more of of four categories: 1) moving data from one location to another (an example might be an instruction that "tells" the CPU to "copy the contents of memory cell 5 and place the copy in cell 10"; 2) executing arithmetic and logical processes on data (for instance, "add the contents of cell 7 to the contents of cell 13 and place the result in cell 20" 3) testing the condition of data ("if the contents of cell 999 are 0, the next instruction is at cell 30") 4) altering the sequence of operations (the previous example alters the sequence of operations, but instructions such as "the next instruction is at cell 100" are also standard).

Instructions, like data, are represented within the computer as binary code — a base two system of counting. For example, the code for one kind of "copy" operation in the Intel x86 line of microprocessors is 10110000 [4]. The particular instruction set that a specific computer supports is known as that computer's machine language. Using an already-popular machine language makes it much easier to run existing software on a new machine; consequently, in markets where commercial software availability is important suppliers have converged on one or a very small number of distinct machine languages.

Larger computers, such as some minicomputers, mainframe computers, servers, differ from the model above in one significant aspect; rather than one CPU they often have a number of them. Supercomputers often have highly unusual architectures significantly different from the basic stored-program architecture, sometimes featuring thousands of CPUs, but such designs tend to be useful only for specialized tasks.

Answer 6

Your workstation doesnt seems lots probs.. Its just about corresponding to mines. yet I somewhat have extra RAM than yours. i'm additionally making use of McAfee antivirus. that is between the desirable. regardless of the undeniable fact that it make the workstation runs slow. Startup will take it slow. I many times disable antivirus many of the time. I activate it as quickly as I open downloaded classes from internet or whilst get entry to exterior storages like floppy,cd,.. you may wish a stable firewall. i'm making use of McAfee firewall. some viruses are unfold without delay, so firewall is could to guard workstation. in case you like extra overall performance, u can improve ur workstation.. get extra beneficial cpu,ram and all.
