 ## [DAY-0] The Computer
 
 All modern computers(laptops, phones, pc master race rgb monsters, etc) have somewhat similar components: Processor, Memory, Video Card, Disk and USB controller, WiFi card etc. Some of them are in one single chip and you cant even see them anymore, but they are there. For example there are chips that have Processor and Video Card together. The term for processor is actually CPU - Central processing unit, but we called it processors when we were kids and it kind of make sense, since it processes stuff.

+> the last 1-2 weeks we were doing ad-hoc small json programs, just serializing and deserializing some state, those are just some of the programs she made

+
+make user.json file
+
+```
+{
+    "name": "Jackie",
+    "favoriteNumber": 14,
+    "IsProgrammer": true,
+    "hobbies": ["learning","volleybal"],
+    "objects": [{"name": "Defalco"},{"idol": "Defalco"}]
+
+}
+```
+
+load it and get some data from the inside objects
+
+```
+import json
+f=open("user.json","r")
+r = f.read()
+#print(r)
+f.close()
+
+data = json.loads(r)
+
+print(data["objects"][1]["idol"])
+```
+
+save some input state:
+```
+import json
+# questions = []
+
+# for i in range(3):
+#     q = input("q> ")
+#     a = input("a> ")
+
+#     questions.append({"question":q, "answer":a })

+# f.close()
+
+f = open("questions.txt",'r')
+data = json.loads(f.read()) # deserialize
+f.close()
+print(data)

+
+some other examples

+
+> we made few other small programs on the way, but I didnt write them down. Also we spent fair amount of time going through the network tab in the chrome inspector and looking at various json payloads
