What Type Of Memory Is Used As Cache Memory And Can Be Much Faster Than DRAM ?
- A.
DRAM
- B.
RAM
- C.
SRAM
- D.
SDRAM
- E.
DDR SDRAM
Correct Answer
C. SRAMExplanation
SRAM (Static Random Access Memory) is the correct answer. SRAM is a type of memory that is commonly used as cache memory. It is faster than DRAM (Dynamic Random Access Memory) because it does not require constant refreshing like DRAM does. SRAM is also faster because it uses flip-flops to store each bit of data, while DRAM uses capacitors. This makes SRAM more expensive and less dense than DRAM, but it provides faster access times, making it ideal for cache memory.Rate this question:

Pick The Correct Statement, What Is a Brownout ?
- A.
Loss of ac power, blown fuse, downed power
- B.
Reduced voltage level of ac power that lasts a period of time
- C.
Interference from generators and lighting, results in unclear power
- D.
Sudden increase in voltage that lasts for a short period of time
- E.
Dramatic increase in voltage lasts for a few nanoseconds
Correct Answer
A. Loss of ac power, blown fuse, downed powerExplanation
A brownout refers to a reduced voltage level of AC power that lasts for a period of time. This can occur due to various factors such as high demand, faulty equipment, or problems with the power grid. Unlike a complete loss of power, a brownout typically results in a decrease in the voltage supplied to electrical devices, which can cause them to operate less efficiently or even malfunction. It is different from a blown fuse or downed power, as it specifically refers to a decrease in voltage rather than a complete loss of power.Rate this question:

Which Type of TCP/IP Attack randomly opens TCP ports?
- A.
SYN Flood
- B.
DDOS
- C.
DOS
- D.
VPN
Correct Answer
A. SYN FloodExplanation
A SYN flood is a type of TCP/IP attack that randomly opens TCP ports. In this attack, the attacker sends a flood of SYN packets to the target server, but never completes the connection by sending the final ACK packet. This causes the server to keep waiting for the ACK packet and leaves the TCP ports open, eventually exhausting the server's resources and making it unable to handle legitimate requests. This attack can lead to denial of service (DoS) as the server becomes overwhelmed with half-open connections.Rate this question:
