HPC computing:

•  It stands for high performance cloud computing which improves the performance by computing by increasing the speed.
• The main motivation behind such computing is improvement in various fields such as engineering and scientific etc..,  which made the speed measure over p-flops and g-flops.
• Modern computing involve desktops or pc connected over LANs and WANs where computing must provide efficient ways to make servers transparent along with faster access.

HTC computing:

• It stands for high throughput computing which focuses on providing concurrent access to the data present over the internet over millions of devices.
• It can be defined as the rate at which the task is carried out.
• Rate can be increased with respect to the number of tasks while decreasing the time. Apart from speeding up the processing it also has the feature to capture the issues associated with cost, security and reliability .
