How much ram memory can you put on a dell OptiPlex gx520?
You can upgrade your Dell OptiPlex GX620 SFF upto a maximum of 4.0 GB, with maximum of 1GB per slot in 4 (2 banks of 2) memory slots. The Dell OptiPlex GX620 SFF takes the PC2-4200 DDR2 SDRAM DIMMs. Supports Dual Channel DDR. Memory Type.
What are memory sockets or slots and how are these divided into bank?
Memory Sockets or Slots are the place where memory RAM modules are inserted in the motherboard. The Dell OptiPlex GX620 SFF has 4 (2 banks of 2) memory expansion slots. A memory bank is a group of memory expansion sockets, a bank must be completely filled with memory modules of the same size and type in order for the system to recognize and address the memory. i.e. :
2 sockets (2 banks of 1) This indicates that there are 2 memory slots. These are divided into 2 banks, and each bank consists of one memory slot. So you can add memory one piece at a time for the system to use.
3 sockets (3 banks of 1) This indicates that there are 3 memory slots. These are divided into 3 banks, and each bank consists of one memory slot. So you can add memory one piece at a time for the system to use.
4 sockets (2 banks of 2) This indicates that there are 4 memory slots. These are divided into 2 banks, and each bank consists of two memory slots. So you must add memory two pieces at a time (they must be the same size and type of memory) in order for the system to benefit from the upgrade.
8 sockets (4 banks of 2) This indicates that there are 8 memory slots. These are divided into 4 banks, and each bank consists of two memory slots. So you must add memory two pieces at a time (they must be the same size and type of memory) in order for the system to benefit from the upgrade.
12 sockets (3 banks of 4) This indicates that there are 12 memory slots. These are divided into 3 banks, and each bank consists of four memory slots. So you must add memory four pieces at a time (and they must be the same size and type of memory) in order for the system to benefit from the upgrade.

Can you replace an AC Adapter of 19.5 V and 3.34 A with a 19.5 V and 4.62 A?
It sounds like you are referring to a universal adapter. A universal ac adaptor has several tips, which adjust the voltage and amperage, and the higher the voltage, the lower the amperage. Therefore, if your adapter is 4.3 amps at 15 volts, it will be significantly lower amperage at 19 volts.
2 KB is 2 kilobytes. A byte is a group of 8 binary digits giving 256 possible combinations of on/off states. Normally kilo means 1000 but in computers it means 1024 because 1024 is a power of 2 that is 210 = 1024. Everything in computers is based on the number 2 because switches, which is what a computer actually is, can only have 2 states, on and off. 2KB is therefore 2048 bytes (characters) This is about an A4 page of ordinary text.
What expansion slots has the potential for the highest speed?
Any expansion slot will only go as fast as it is designed to do. The faster the board is designed to go the more potential for more speed
Why CPU and memory are not connected directly with peripheral devices?
If they were, the devices would all have to have a separate interpreter for the processor and in order to communicate amongst themselves they'd have to go through the processor, which would slow the computer down. If everything is connected to the motherboard and the motherboard interprets everything for the processor, it's cheaper and faster.
What are disadvantages of slide projector?
Some advantages of using a slide presentation is the ease of use and the ability to maintain eye contact due to the lack of needed handouts. Disadvantages are that slide can oversimplify complex topics and the cost of the equipment needed to run a slide presentation.
Why does my computer make a grinding noise when it turns on?
If you have this problem, you probably have a 1 year old or more computer.
It makes the "grindstone" sound because it is using the fans to cool down the system. However, the fans are worn out, so they make noise. The plastic wore away the inside part of the fan (attached to what spins it) and it bumps around where it's trapped. Simple as that.
What is an internal peripheral?
Some examples of internal peripheral devices are cd/dvd drives, internal modems, and e-card readers.
How can we replace CMOS battery in a PC?
Most PC motherboards use a coin cell battery as a CMOS battery backup for BIOS settings. Most common battery used for this application is CR3032 and can be easily replaced. You can turn off the computer, remove power cables, open the machine and locate this coin cell on the motherboard and remove old battery from the socket with a plastic tool or your finger nails and then insert a new one in the socket. If using a metal tool/screw driver be careful that you do not short upper and lower side of the coin cell (which can cause a short circuit, can create a spark and will damage the battery).
What are the main functions of the main board?
The purpose of a computer board is to act as a main frame between all the computers working components. Without it, the computer would simply not run.

Which port has the fastest data transfer rate?
Short answer: Just use USB 3.0
Long Answer:
Depends what you mean by "port." As an external port, you would probably want to go with USB 3.0. However, if you want the fastest data transfer rate, you can buy an internal SSD and connect it to the motherboard with Serial ATA. Be careful, because many parts on the inside of a computer are very delicate. Hope this helps.
What is the input device used for rapidly reading large quantities of information?
You could get a microphone and a program like speech to text to convert it, or, if you already have a file typed up on a different computer, you could transfer it using a flash drive.
