What Is Cache?

Cache is memory that contains information recently accessed by a computer’s CPU. A CPU can access the cache very fast and frees up space that would otherwise be used on RAM. Images and web addresses are a good example of what the cache stores for faster access. A bottleneck exists between the CPU and RAM. This bottleneck is a reason cache is necessary for faster computing. There are 3 types of cache that are integrated in a computer.Learn More About Cache With Free Computer Maintenance

What is SMTP and POP3?

SMTP and POP3 are protocols used to facilitate email traffic between computers. Every time an email is sent it goes through a set of protocols that ensure security and allow conversation between the client and the host. SMTP is used along side of POP3 in a workplace environment.

“That Bytes!” Defining Megabyte, Gigabyte, Bits, and Bytes

What is a megabyte, gigabyte, bit, and byte?
Free Computer Maintenance byte

byte – a unit of measure for digital information equal to 8 bits.

i.e. “You have 200 gigabytes of free space on your hard drive.”
“Your photo is too large. Please upload a file under 4MB (megabytes).”

One of my computer science professors in college explained it this way:

Your computer stores information in cubby holes – lots of cubby holes. One cubby hole can hold one bit of information. One byte equals 8 bits of information. Computers only understand numbers, so each bit, or each cubby hole,
